The development of agoraphobia is associated with the symptoms and location of a patient's first panic attack

PubMed Central

2012-01-01

Background The place where a patient experiences his/her first panic attack (FPA) may be related to their agoraphobia later in life. However, no investigations have been done into the clinical features according to the place where the FPA was experienced. In particular, there is an absence of detailed research examining patients who experienced their FPA at home. In this study, patients were classified by the location of their FPA and the differences in their clinical features were explored (e.g., symptoms of FPA, frequency of agoraphobia, and severity of FPA). Methods The subjects comprised 830 panic disorder patients who were classified into 5 groups based on the place of their FPA (home, school/office, driving a car, in a public transportation vehicle, outside of home), The clinical features of these patients were investigated. Additionally, for panic disorder patients with agoraphobia at their initial clinic visit, the clinical features of patients who experienced their FPA at home were compared to those who experienced their attack elsewhere. Results In comparison of the FPAs of the 5 groups, significant differences were seen among the 7 descriptors (sex ratio, drinking status, smoking status, severity of the panic attack, depression score, ratio of agoraphobia, and degree of avoidance behavior) and 4 symptoms (sweating, chest pain, feeling dizzy, and fear of dying). The driving and public transportation group patients showed a higher incidence of co-morbid agoraphobia than did the other groups. Additionally, for panic disorder patients with co-morbid agoraphobia, the at-home group had a higher frequency of fear of dying compared to the patients in the outside-of-home group and felt more severe distress elicited by their FPA. Conclusion The results of this study suggest that the clinical features of panic disorder patients vary according to the place of their FPA. The at-home group patients experienced "fear of dying" more frequently and felt more distress during their FPA than did the subjects in the other groups. These results indicate that patients experiencing their FPA at home should be treated with a focus on the fear and distress elicited by the attack. PMID:22494552

Among 148 patients presenting Panic Disorder (DSM-III-R), 18.9% have an alcohol disorder, 8.8% present abuse and 10.1% dependence. Mean age of onset of alcoholism was much earlier than panic disorder. Patients with alcoholism: a) are males more frequently (0.001); b) present more alcoholism in first grade relatives (0.05); c) use more often other drugs like: tobacco (0.01), coffee (p < 0.01), cocaine (p < 0.01) and cannabis (p < 0.001), d) patients with alcoholism refer a greater severity of their panic attacks when drinking large amounts of alcohol (25%) than the group without these problems (2.5%) (x2:14.8) (p < 0.001) e) according to the GAS the overall level of performance is lower in alcoholics (p < 0.005); f) present more anxiety measured by the HARS (p < 0.01), and therefore have more comorbid anxiety disorders according to DSM-III-R (p < 0.01). The clinical significance of these findings is discussed.

Recent evidence suggests that there may be more than one Gilles de la Tourette syndrome (GTS)/tic disorder phenotype. However, little is known about the common patterns of these GTS/tic disorder-related comorbidities. In addition, sex-specific phenomenological data of GTS/tic disorder-affected adults are rare. Therefore, this community-based study used latent class analyses (LCA) to investigate sex-related and non-sex-related subtypes of GTS/tic disorders and their most common comorbidities. The data were drawn from the PsyCoLaus study (n = 3691), a population-based survey conducted in Lausanne, Switzerland. LCA were performed on the data of 80 subjects manifesting motor/vocal tics during their childhood/adolescence. Comorbid attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder, depressive, phobia and panic symptoms/syndromes comprised the selected indicators. The resultant classes were characterized by psychosocial correlates. In LCA, four latent classes provided the best fit to the data. We identified two male-related classes. The first class exhibited both ADHD and depression. The second class comprised males with only depression. Class three was a female-related class depicting obsessive thoughts/compulsive acts, phobias and panic attacks. This class manifested high psychosocial impairment. Class four had a balanced sex proportion and comorbid symptoms/syndromes such as phobias and panic attacks. The complementary occurrence of comorbid obsessive thoughts/compulsive acts and ADHD impulsivity was remarkable. To the best of our knowledge, this is the first study applying LCA to community data of GTS symptoms/tic disorder-affected persons. Our findings support the utility of differentiating GTS/tic disorder subphenotypes on the basis of comorbid syndromes. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

Test of the role of nicotine dependence in the relation between posttraumatic stress disorder and panic spectrum problems.

Posttraumatic stress disorder (PTSD) frequently co-occurs with panic spectrum problems. Relatively little empirical work has tested possible mechanisms accounting for this association. Nicotine dependence often ensues subsequent to PTSD onset and research suggests smoking high numbers of cigarettes daily may lead to panic problems. The current study tested the hypotheses that nicotine dependence partially mediates the relations between PTSD and both panic attacks and panic disorder within a nationally representative sample of 5,692 (3,020 women; M(Age) = 45, SD = 18) adults from the National Comorbidity Survey-Replication. Results were consistent with hypotheses. These findings support the theory suggesting smoking among people with PTSD may be involved in the development of panic problems.

Examining the Panic Attack Specifier in Social Anxiety Disorder.

Allan, Nicholas P; Oglesby, Mary E; Short, Nicole A; Schmidt, Norman B

Panic attacks (PAs) are characterized by overwhelming surges of fear and discomfort and are one of the most frequently occurring symptoms in psychiatric populations. The most recent version of the Diagnostic and Statistical Manual of Mental Disorders (i.e. DSM-5) allows for a panic attack (PA) specifier for all disorders, including social anxiety disorder (SAD). However, there is little research examining differences between individuals diagnosed with SAD with the PA specifier versus individuals diagnosed with SAD without the PA specifier. The current study examined social anxiety, mood, anxiety, and anxiety sensitivity social concerns, a risk factor for social anxiety in SAD-diagnosed individuals without (N = 52) and with (N = 14) the PA specifier. The groups differed only in somatic symptoms of anxiety. Result of the current study provides preliminary evidence that the presence of the PA specifier in social anxiety does not result in elevated levels of comorbidity or a more severe presentation of social anxiety.

Carbon dioxide induces erratic respiratory responses in bipolar disorder.

CO(2) respiration stimulates both anxiety and dyspnea ("air hunger") and has long been used to study panic vulnerability and respiratory control. High comorbidity with panic attacks suggests individuals with bipolar disorder may also mount a heightened anxiety response to CO(2). Moreover, problems in the arousal and modulation of appetites are central to the clinical syndromes of mania and depression; hence CO(2) may arouse an abnormal respiratory response to "air hunger". 72 individuals (34 bipolar I, 25 depressive and bipolar spectrum, 13 with no major affective diagnosis) breathed air and air with 5% CO(2) via facemask for up to 15 min each; subjective and respiratory responses were recorded. Nearly half the subjects diverged from the typical response to a fixed, mildly hypercapneic environment, which is to increase breathing acutely, and then maintain a hyperpneic plateau. The best predictors of an abnormal pattern were bipolar diagnosis and anxiety from air alone. 25 individuals had a panic response; panic responses from CO(2) were more likely in subjects with bipolar I compared to other subjects, however the best predictors of a panic response overall were anxiety from air alone and prior history of panic attacks. Heterogeneous sample, liberal definition of panic attack. Carbon dioxide produces abnormal respiratory and heightened anxiety responses among individuals with bipolar and depressive disorders. These may be due to deficits in emotional conditioning related to fear and appetite. Although preliminary, this work suggests a potentially useful test of a specific functional deficit in bipolar disorder.

Panic disorder affects 2-5% of the general population. In Argentina, one million people would be affected with a 91% rate of psychiatric comorbidity. AIM; To compare efficacy parameters between sublingual (ALP-SL) and conventional (ALP-CT) tablets of alprazolam in the treatment of acute phase of panic disorder with and without agoraphobia. A comparative, multicenter (6 sites), double blind, randomized study was carried out. A total of 190 outpatients with (n=117) and without (n=73) agoraphobia were treated with ALP-SL or ALP-CT for 12 weeks. Outcome was assessed with the Clinical Global Impressions (CGI-S/CGI-I), Hamilton Rating Scale for Anxiety (HAM-A), Arizona Sexual Experiences Scale (ASEX), Patient Global Impression (PGI), Psychological General Well-Being Index (PGWBI), Panic Disorder Severity Scale (PDSS) also by the number of panic attacks and extension and intensity of panic attacks and anticipatory anxiety. RESULTS. Both treatments resulted in statistically significant clinical improvement in all measures. ASEX presented no changes during the study. The average dose of alprazolam for 12 weeks was 1.36 ± 0.70 mg/day (1.39 ± 0.77 ALP-CT and 1.33 ± 0.64 ALP-SL). With ALP-SL, panic attacks were shorter (p < 0.05) with shorter extension (p=0.16) and intensity of anticipatory anxiety (p=0.14). The treatment was well tolerated, there being no differences between both groups. Alprazolam has been demonstrated to have efficacy, safety and good tolerability in the treatment of the acute phase of panic disorder, the sublingual tablets showing some comparative advantages.

We have previously reported that 35% CO2 challenge induced myocardial ischemia in 81% of coronary artery disease (CAD) patients with comorbid panic disorder (PD) and previous positive nuclear exercise stress tests. However, it is yet unclear whether this is the case among CAD patients with PD and normal nuclear exercise stress test results. We hypothesized that a potent mental stressor such as a panic challenge among CAD patients with PD would also induce ischemia in patients with normal exercise stress tests. Forty-one coronary artery disease patients with normal nuclear exercise stress tests (21 patients with PD and 20 without PD) were submitted to a well-established panic challenge test (with 1 vital capacity inhalation of a gas mixture containing 35% CO2 and 65% O2) and injected with Tc-99m-tetrofosmin (Myoview), upon inhalation. Single photon emission computed tomography imaging was used to assess per-panic challenge reversible myocardial ischemia and HR, BP, and a 12 lead ECG was continuously measured during the procedure. Fifty-eight percent of panic disorder patients (12/21) had a panic attack during the panic challenge vs 15% (3/20) of controls (p=0.005). Only 10% of patients in each group displayed myocardial ischemia per panic challenge. These findings suggest that panic attacks among panic disorder patients with lower-risk coronary artery disease may not confer a risk for myocardial ischemia. © 2013.

An 18-year-old man with Arnold-Chiari malformation (ACM) type I developed sudden panic attacks. He also manifested sleep disorder, cannabis abuse, and psychosis-risk syndrome (PRS). Although with average-superior intelligence, he had executive dysfunction. This prompted us to explore the relation between ACM, cannabis abuse, PRS and panic disorder. We report the case and briefly review the literature focusing on ACM and psychiatric disorders. Behavior therapy led to gradual abstinence from cannabis with disappearance of anxiety symptoms. The patient is currently well and maintained on omega-3 polyunsaturated fatty acids. Locus coeruleus compression and cannabis abuse may have triggered the symptoms, and the latter might also be PRS-related. PRS and anxiety symptoms should be explored in ACM patients to allow better prevention of psychosis and anxiety disorders. Copyright © 2012 Elsevier Inc. All rights reserved.

Panic attacks occurring outside of Panic Disorder are not well-understood despite their inclusion as a diagnostic specifier in the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). This study compares panic attacks in the context of Panic Disorder compared to social anxiety in terms of their symptom frequency, severity, and clinical correlates. Participants (n=404) were interviewed using the Anxiety Disorders Interview Schedule (ADIS-IV-L; Brown et al., 1994), from which we analyzed interviewer ratings of panic attacks and panic attack symptoms, as well as other demographic and clinical characteristics. Panic attacks in the context of Panic Disorder were characterized by a greater number and severity of symptoms compared to panic attacks in the context of Social Anxiety Disorder, and were associated with a history of traumatization, inpatient psychiatric treatment, and benzodiazepine use. Social anxiety panic attacks were associated with reduced physical health concerns. Cognitive panic attack symptoms were more prevalent in Panic Disorder and were associated with a variety of poor clinical correlates. Panic attacks in the context of Panic Disorder are more severe than those in social anxiety, and this may be driven by cognitive disturbances during those attacks.

Especially in the presence of agoraphobia and comorbid conditions, panic disorder causes significant impairment in life quality. Although there are several studies about epidemiology and clinical features, subthreshold symptoms and courses of comorbidity have not been studied sufficiently in panic disorder. The current study assessed the courses of panic disorder and subthreshold panic symptoms in consideration of the major and subthreshold comorbid conditions. Patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-diagnosed panic disorder were assessed using the panic disorder follow-up questionnaire, Panic and Agoraphobia Scale, Hamilton Depression Rating Scale, and State-Trait Anxiety Inventory. Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders was used to determine comorbidity, and all participants were received to 1-year follow-up. Comorbidity assessment showed that the threshold comorbidity decreased, while the subthreshold comorbidity increased at 1-year follow-up. Panic disorder symptom severity was decreased, but subthreshold panic symptoms continued to be present within the course of the illness. Presence of agoraphobia and duration of disease were significantly related with higher Panic and Agoraphobia Scale scores in the second assessment, and these relationships were independent from the treatment process. Even if the comorbidity and the severity of panic decrease with treatment, subthreshold panic and comorbid symptoms may still resist in panic disorder. Copyright © 2012 Elsevier Inc.

2004-01-01

There is currently no way of knowing whether a patient who has recently had a single panic attack has incipient panic disorder. Sensitivity to carbon dioxide (CO2) is lower in healthy volunteers than in panic disorder patients. If this is also true of people who experience a single lifetime panic attack, it could be used as a prognostic test. Subjects with a single lifetime panic attack and subjects with panic disorder received an inhalation of 35% CO2. Subjects completed the panic symptoms scale (PSS), and also stated whether they considered that they had experienced an attack. None of 14 subjects with a single lifetime panic attack, compared to 7 of 17 subjects with panic disorder (P=.009), had an attack. The PSS also distinguished between the groups. The 35% CO2 challenge warrants further investigation as a predictive test after a first panic attack.

Panic attacks are frequently perceived as life threatening. Panic disorder (PD) patients may therefore experience symptoms of posttraumatic stress disorder (PTSD). The authors explored this in 28 healthy controls, 17 PTSD patients, and 24 PD patients with agoraphobia who completed electronic diaries 36 times during 1 week. Patient groups frequently reported dissociation as well as thoughts, memories, and reliving of their trauma or panic attacks. PTSD patients reported more trauma/panic attack thoughts (incidence rate ratio [IRR] = 2.9) and memories (IRR = 2.8) than PD patients. Patient groups relived their trauma or panic attacks equally frequently, and reported comparable bodily reactions and distress associated with trauma or panic attack memories. Clinical groups avoided trauma or panic attack reminders more often than healthy controls (avoidance of trauma- or panic attack-related thoughts (IRR = 8.0); avoidance of things associated with the trauma or panic attack (IRR = 40.7). PD patients avoided trauma or panic attack reminders less often than PTSD patients (avoidance of trauma- or panic attack-related thoughts [IRR = 2.5]; avoidance of things associated with the trauma or panic attack [IRR = 4.1]), yet these differences were nonsignificant when controlling for functional impairment. In conclusion, trauma-like symptoms are common in PD with agoraphobia and panic attacks may be processed similarly as trauma in PTSD.

Phenomenology of panic attacks: a descriptive study of panic disorder patients' self-reports.

PubMed

Aronson, T A; Logue, C M

1988-01-01

The phenomenology of panic disorder and panic attacks was systematically assessed in 46 consecutive patients. The results suggest that DSM-III criteria include several symptoms that are not frequently present during a panic attack and that DSM-III's characterization of a panic attack is imprecise and misleading. Panic attacks were found to vary in intensity, frequency, spontaneity, and associated symptoms. A panic attack typically presents as a unified symptom complex of psychic anxiety and multiple somatic symptoms in multiple body systems. It occurs in a crescendolike pattern, is self-limited, and often leaves the subject weak or shaken. The temporal course as much as the symptomatic presentation defines a panic attack.

Since its development in the mid-1980s, the Panic Attack Questionnaire (PAQ) has been one of the more, if not the most, commonly used self-report tools for assessing panic attacks. The usage of the instrument, however, has come amid potential concerns that instructions and descriptions may lead to an over-estimate of the prevalence of panic attacks. Furthermore, the instrument has not been revised since 1992, despite changes in DSM-IV criteria and more recent developments in the understanding of panic attacks. As a result, this paper describes a revision of the PAQ to improve the instruction and descriptive set, and to fully assess features of panic derived from recent conceptualizations. Students meeting DSM-IV panic attack criteria and those endorsing panic attacks, but not meeting criteria, showed few differences with the exception that those not meeting DSM-IV criteria typically reported a longer onset-to-peak intensity time than did Panickers. Results were cross-validated and extended using an independent Community Sample. A full descriptive phenomenology of panic attacks is described, and future directions for studying panic attacks using the PAQ are presented.

The factors contributing to psychiatric problems among military personnel, particularly for panic, are unclear. The objective of this study was to examine the prevalence and correlates of panic disorder and panic attacks in the Canadian military. Statistics Canada and the Department of National Defense conducted the Canadian Community Health Survey-Canadian Forces Supplement in 2002 (May to December) with a representative sample of active Canadian military personnel (aged 16-54 years; N = 8,441; response rate, 81.5%). Comparisons were made between respondents with no past-year panic attacks, panic attacks without panic disorder, and panic disorder on measures of DSM-IV mental disorders, as well as validated measures of disability, distress, suicidal ideation, perceived need for mental health treatment, and mental health service use. Lifetime exposure to combat operations, witnessing of atrocities, and deployments were also assessed. Panic disorder and panic attacks were common in the military population, with past-year prevalence estimates of 1.8% and 7.0%, respectively. Both panic disorder and panic attacks were associated with increased odds of all mental disorders assessed, suicidal ideation, 2-week disability, and distress. Perceived need for mental health treatment and service use were common in individuals with panic attacks and panic disorder (perceived need: 46.3% for panic attacks, 89.6% for panic disorder; service use: 32.5% for panic attacks, 74.5% for panic disorder). Panic attacks and panic disorder in the military are associated with outcomes that could be detrimental to well-being and work performance, and early detection of panic in this population could help reduce these negative outcomes. © Copyright 2011 Physicians Postgraduate Press, Inc.

2009-01-01

The current study investigates race-ethnic differences in rates of panic disorder, panic attacks and certain panic attack symptoms by jointly combining three major national epidemiological databases. The compared groups were White, African American, Latino and Asian. The White group had significantly higher rates of panic disorder, and of many panic symptoms, including palpitations, as compared to the African American, Asian and Latino groups. Several expected race-ethnic differences were not found. An explanation for these findings are adduced, and suggestions are given for future studies so that possible ethnic-racial differences in panic disorder, panic attacks and panic attack symptoms can be investigated in a more rigorous manner.

The present study is the first to attempt to determine rates of panic attacks, especially ‘somatically focused’ panic attacks, panic disorder, symptoms of post-traumatic stress disorder (PTSD), and depression levels in a population of Rwandans traumatized by the 1994 genocide. The following measures were utilized: the Rwandan Panic-Disorder Survey (RPDS); the Beck Depression Inventory (BDI); the Harvard Trauma Questionnaire (HTQ); and the PTSD Checklist (PCL). Forty of 100 Rwandan widows suffered somatically focused panic attacks during the previous 4 weeks. Thirty-five (87%) of those having panic attacks suffered panic disorder, making the rate of panic disorder for the entire sample 35%. Rwandan widows with panic attacks had greater psychopathology on all measures. Somatically focused panic-attack subtypes seem to constitute a key response to trauma in the Rwandan population. Future studies of traumatized non-Western populations should carefully assess not only somatoform disorder but also somatically focused panic attacks. PMID:12581815

Panic disorder respiratory subtype: psychopathology, laboratory challenge tests, and response to treatment.

Our objective is to summarize the new findings concerning the respiratory subtype (RS) of panic disorder (PD) since its first description. Two searches were made in the Institute for Scientific Information Web of Science: with the keywords "panic disorder" and "respiratory symptoms," and all articles that cited Briggs and colleagues' 1993 article "Subtyping of Panic Disorder by Symptom Profile" (Br J Psychiatry 1993;163:201-9). Altogether, 133 articles were reviewed. We describe and discuss RS epidemiology, genetics, psychopathology, demographic features, clinical features, correlations with the respiratory system, traumatic suffocation history, provocative tests, and nocturnal panic. Compared to patients with the nonrespiratory subtype (non-RS), the RS patients had higher familial history of PD, lower comorbidity with depression, longer duration of illness, lower neuroticism scores, and higher scores in severity scales, such as the Panic and Agoraphobia Scale, Panic-Agoraphobia Spectrum scale and the Clinical Global Impression scale. Tests to induce panic attacks, such as those with CO(2), hyperventilation, and caffeine, produce panic attacks in a higher proportion of RS patients than non-RS patients. Differences in the subtypes' improvement with the pharmacologic treatment were found. There are also some controversial findings regarding the RS, including the age of onset of PD, and alcohol and tobacco use in RS patients. Some characteristics, such as the increased sensitivity to CO(2) and the higher familial history of PD, clearly distinguish the RS from the non-RS. Nevertheless, there are also controversial findings. More studies are needed to determine the validity of the RS subtype.

Panic attacks are a source of individual suffering and are an independent risk factor for later psychopathology. However, much less is known about risk factors for the development of panic attacks, particularly during adolescence when the incidence of panic attacks increases dramatically. We examined whether internalizing and externalizing problems in childhood predict the onset of panic attacks in adolescence. This study is part of the TRacking Adolescents' Individual Lives Survey (TRAILS), a Dutch longitudinal population cohort study (N = 1,584). Internalizing and Externalizing Problems were collected using the Youth Self-Report (YSR) and the parent-report Child Behavior Checklist (CBCL) at baseline (age 10-12). At age 18-20, DSM-IV defined panic attacks since baseline were assessed with the Composite International Diagnostic Interview (CIDI). We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10-20 years, using survival analysis in univariate and multivariate models. There were N = 314 (19.8%) cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2%) who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset. In multivariate analyses, CBCL Social Problems (HR 1.19, p<.05), and YSR Thought Problems (HR 1.15, p<.05) and Social Problems (HR 1.26, p<.01) predicted panic attack onset. Risk indicators of panic attack include the wide range of internalizing and externalizing problems. Yet, when adjusted for co-occurring problem behaviors, Social Problems were the most consistent risk factor for panic attack onsets in adolescence.

Individuals with anxiety often report greater smoking and drinking behaviors relative to those without a history of anxiety. In particular, smoking and alcohol use have been directly implicated among individuals experiencing panic attacks, diagnosed with panic disorder, or high on panic-relevant risk factors such as anxiety sensitivity. Less is known, however, about specific features of panic that may differentiate among those who do or do not use cigarettes or alcohol. The purpose of the current study was to replicate previous research findings of an association between panic symptomatology, cigarette smoking, and alcohol consumption, as well as extend findings by examining whether specific symptoms of panic attacks differentiated among those who do or do not use cigarettes or alcohol. Participants (n = 489) completed the Panic Attack Questionnaire-IV, a highly detailed assessment of panic attacks and symptoms, as well as self-report measures of smoking history and alcohol use. Consistent with previous research, participants who reported a history of panic attacks (n = 107) were significantly more likely to report current daily or lifetime daily cigarette smoking, and significantly greater hazardous or harmful alcohol use than participants with no panic history (n = 382). Although smoking and hazardous alcohol use were highly associated regardless of panic status, participants with panic attacks showed elevated hazardous alcohol use after controlling for daily or lifetime smoking. Surprisingly, although participants who reported having had at least one panic attack were more likely to smoke, panic attack symptoms, intensity, or frequency did not differentiate panickers who did or did not smoke. Furthermore, panic-related variables were not shown to differentially relate to problematic drinking among panickers. Implications for understanding the complex relationship between panic attacks and smoking and drinking behaviors are discussed. PMID:21915160

Previous studies of the dimensional structure of panic attack symptoms have mostly identified a respiratory and a vestibular/mixed somatic dimension. Evidence for additional dimensions such as a cardiac dimension and the allocation of several of the panic attack symptom criteria is less consistent. Clarifying the dimensional structure of the panic attack symptoms should help to specify the relationship of potential risk factors like anxiety sensitivity and fear of suffocation to the experience of panic attacks and the development of panic disorder. In an outpatient multicentre study 350 panic patients with agoraphobia rated the intensity of each of the ten DSM-IV bodily symptoms during a typical panic attack. The factor structure of these data was investigated with nonlinear confirmatory factor analysis (CFA). The identified bodily symptom dimensions were related to panic cognitions, anxiety sensitivity and fear of suffocation by means of nonlinear structural equation modelling (SEM). CFA indicated a respiratory, a vestibular/mixed somatic and a cardiac dimension of the bodily symptom criteria. These three factors were differentially associated with specific panic cognitions, different anxiety sensitivity facets and suffocation fear. Taking into account the dimensional structure of panic attack symptoms may help to increase the specificity of the associations between the experience of panic attack symptoms and various panic related constructs.

We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10–20 years, using survival analysis in univariate and multivariate models. Results There were N = 314 (19.8%) cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2%) who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset. In multivariate analyses, CBCL Social Problems (HR 1.19, p<.05), and YSR Thought Problems (HR 1.15, p<.05) and Social Problems (HR 1.26, p<.01) predicted panic attack onset. Conclusion Risk indicators of panic attack include the wide range of internalizing and externalizing problems. Yet, when adjusted for co-occurring problem behaviors, Social Problems were the most consistent risk factor for panic attack onsets in adolescence. PMID:23251576

Among one hundred patients with alcohol dependence (DSM-III-R) studied in a drug abuse center in the "Bajo Llobregat" area (Barcelona industrial belt it was detected that 27% had life time rate of panic disorder. The age of onset of alcoholism was earlier than the one for panic disorder. In 78.8% of these patients alcoholismo appeared first. 70.4% refer worsening of the panic attacks when drinking large amounts of alcohol. Patients with Panic Disorder: a) are younger (p < 0.05); b) have attended school longer and have higher education (p < 0.01); c) have more alcoholism family history (p < 0.05); d) have more major depressive disorders (0.05) and dysthimic disorder (p < 0.01); e) Worse social functioning according to the GAS (p < 0.01); f) higher score for the Psychological disorders Scale (p < 0.001) and a lower performance at work (p < 0.001) measured by the ASI. The clinical significance of these findings is discussed.

Anxiety has been linked to onset of cardiovascular disease. This study examines the differential impact of types of anxiety (panic, phobia and worry) on 3-year onset of non-fatal cardiovascular disease (CVD). By investigating anxiety disorders as opposed to anxiety symptoms and by using a reliable diagnostic instrument to assess anxiety, limitations of previous studies are considered. 5149 persons at risk for CVD were interviewed using the Composite International Diagnostic Interview. The panic-type included panic disorder and panic attacks; the phobic-type included agoraphobia and social phobia, and the worry-type included generalized anxiety disorder. CVD was self-reported and required treatment or monitoring by a doctor. Analyses were adjusted for sociodemographics, behavioral variables, and comorbid somatic and psychiatric disorders. During follow-up, 62 persons (1.2%) developed CVD. Baseline generalized anxiety disorder was strongly associated with onset of CVD (adjusted OR: 3.39). Further research should replicate findings and focus on biological underpinnings of this association. Copyright © 2014 Elsevier Ltd. All rights reserved.

Cued Panic Attacks in Body Dysmorphic Disorder

Background Body dysmorphic disorder (BDD) is a common and often severe disorder. Clinical observations suggest that panic attacks triggered by BDD symptoms may be common. However, to our knowledge, no study has examined such panic attacks in BDD. We investigated the prevalence, clinical features, and correlates of BDD-triggered panic attacks in individuals with this disorder. Methods Panic attacks and other variables were assessed using reliable and valid measures in 76 individuals with lifetime DSM-IV BDD. Results 28.9% (95% CI, 18.5%–39.4%) of participants reported lifetime panic attacks triggered by BDD symptoms. The most common triggers of such attacks were feeling that others were looking at or scrutinizing the perceived appearance defects (61.9%), looking in the mirror at perceived defects (38.1%), and being in bright light where perceived defects would be more visible (23.8%). The most common panic attack symptoms were palpitations (86.4%), sweating (66.7%), shortness of breath (63.6%), trembling or shaking (63.6%), and fear of losing control or going crazy (63.6%). Compared to participants without such panic attacks, those with BDD-triggered panic attacks had more severe lifetime BDD, social anxiety, and depressive symptoms, as well as poorer functioning and quality of life on a number of measures. They were also less likely to be employed and more likely to have been psychiatrically hospitalized and to have had suicidal ideation due to BDD. Conclusions Panic attacks triggered by BDD-related situations appear common in individuals with this disorder. BDD-triggered panic attacks were associated with greater symptom severity and morbidity.

Previous studies on neuronal activation correlates of panic attacks were mostly based on challenge tests, sensory-related stimulation or fear conditioning in healthy subjects. In the present study, we report on a female patient with panic disorder experiencing a spontaneous panic attack under an auditory habituation paradigm in the last stimulation block with sine tones captured with fMRI at 3T. The panic attack was associated with a significantly increased activity in the right amygdala. This is the first report on neuronal activation correlates of a spontaneous panic attack in a patient with panic disorder as measured by fMRI, which lends further support to a pivotal role of the amygdala in the pathogenesis of the disease.

This study examined the prevalence of emergency department visits prompted by panic attacks in patients with non-cardiac chest pain. A validated structured telephone interview was used to assess panic attacks and their association with the emergency department consultation in 1327 emergency department patients with non-cardiac chest pain. Patients reported at least one panic attack in the past 6 months in 34.5 per cent (95% confidence interval: 32.0%-37.1%) of cases, and 77.1 per cent (95% confidence interval: 73.0%-80.7%) of patients who reported panic attacks had visited the emergency department with non-cardiac chest pain following a panic attack. These results indicate that panic attacks may explain a significant proportion of emergency department visits for non-cardiac chest pain.

Objective Although 70–80% of panic disorder patients use primary care to obtain mental health services, relatively few studies have examined panic patients in this setting. This study aimed to examine both the lifetime and current comorbid psychiatric disorders associated with panic disorder in primary care, the duration and severity of the disorder, and the sociodemographic factors associated with it. Design Patients were screened for panic disorder. Panic disorder and the comorbid disorders were determined using the Structured Clinical Interview for DSM-IV Axis I and II. Setting Eight different health care centers in primary care in the city of Espoo. Subjects Finnish-speaking, between 18 and 65 years of age. Main outcome measures Comorbid psychiatric disorders, the duration and severity of the disorder, and the sociodemographic factors. Results A sample of 49 panic disorder patients and 44 patients with no current psychiatric diagnosis were identified; 98% of panic disorder patients had at least one comorbid lifetime DSM-IV Axis I disorder. Major depressive disorder and other anxiety disorders were most common comorbid disorders. Lifetime alcohol use disorders also showed marked frequency. Interestingly, the remission rates of alcohol use disorders were notable. The panic symptoms appeared to persist for years. Panic disorder was associated with low education and relatively low probability of working full time. Conclusions Also in primary care panic disorder is comorbid, chronic, and disabling. It is important to recognize the comorbid disorders. High remission rates of comorbid alcohol use disorders encourage active treatment of patients also suffering from these disorders. PMID:23113695

In cognitive theory it is hypothesized that panic attacks are provoked by catastrophic misinterpretations of bodily sensations. The aim of the present study was to investigate the ability of associated word pairs referring to catastrophic thinking (e.g. palpitations-heart attack) in producing panic attacks. Patients with PD (n = 20), patients with mixed anxiety disorders (n = 20), and a healthy control group (n = 30) participated in the present study. To enhance ecological validity we first conducted a stimulus validation experiment. Subsequently, nine suitable panic and neutral word pairs were presented in block to the participants. Anxiety levels were assessed before and after the presentation. PD patients were more anxious when reading these word pairs, compared to neutral word pairs. However, none of the participants experienced a panic attack upon reading the word pairs. From the present results it seems that catastrophic thinking is rather related to the anticipatory anxiety for panic attacks, but not necessarily with the occurrence of the panic attacks themselves.

The purpose of the present study was to elucidate a longitudinal matrix of the etiology for first-episode panic attack among white-collar workers. A path model was designed for this purpose. A 5-year, open-cohort study was carried out in a Japanese company. To evaluate the risk factors associated with the onset of a first episode of panic attack, the odds ratios of a new episode of panic attack were calculated by logistic regression. The path model contained five predictor variables: gender difference, overprotection, neuroticism, lifetime history of major depression, and recent stressful life events. The logistic regression analysis indicated that a person with a lifetime history of major depression and recent stressful life events had a fivefold and a threefold higher risk of panic attacks at follow up, respectively. The path model for the prediction of a first episode of panic attack fitted the data well. However, this model presented low accountability for the variance in the ultimate dependent variables, the first episode of panic attack. Three predictors (neuroticism, lifetime history of major depression, and recent stressful life events) had a direct effect on the risk for a first episode of panic attack, whereas gender difference and overprotection had no direct effect. The present model could not fully predict first episodes of panic attack in white-collar workers. To make a path model for the prediction of the first episode of panic attack, other strong predictor variables, which were not surveyed in the present study, are needed. It is suggested that genetic variables are among the other strong predictor variables. A new path model containing genetic variables (e.g. family history etc.) will be needed to predict the first episode of panic attack.

Panic attacks are sudden debilitating attacks of intense distress often accompanied by physical symptoms such as shortness of breath and heart palpitations. Numerous brain regions, hormones, and neurotransmitter systems are putatively involved, but the etiology and neurocircuitry of panic attacks is far from established. One particular brain region of interest is the ventromedial hypothalamus (VMH). In cats and rats, electrical stimulation delivered to the VMH has been shown to evoke an emotional "panic attack-like" escape behavior, and in humans, stimulation targeting nuclei just posterior or anterior to the VMH has reportedly induced panic attacks. The authors report findings obtained in an awake patient undergoing bilateral implantation of deep brain stimulation electrodes into the hypothalamus that strongly implicates the VMH as being critically involved in the genesis of panic attacks. First, as the stimulating electrode progressed deeper into the VMH, the intensity of stimulation required to evoke an attack systematically decreased; second, while stimulation of the VMH in either hemisphere evoked panic, stimulation that appeared to be in the center of the VMH was more potent. Thus, this evidence supports the role of the VMH in the induction of panic attacks purported by animal studies.

The association between trauma exposure and panic attacks has received increased attention over the past decade, with mounting evidence suggesting an overlapping etiologic pathway. This study examined the incidence of new onset panic attacks in 775 Vietnamese individuals in the 2–3 months following Typhoon Xangsane. Pre-typhoon (Wave 1) and post-typhoon (Wave 2) assessments were conducted, allowing for consideration of factors occurring prior to the typhoon in addition to typhoon-relevant responding. Of the 775 participants, 11.6% (n=90) met criteria for lifetime panic attack pre-typhoon and 2.8% (n=22) met post-typhoon panic attack criteria. Individuals with pre-typhoon panic were significantly older and reported less education compared to the no-panic group. Individuals in both panic groups were more likely to screen positive on a Wave1 psychiatric screening measure, endorse greater typhoon exposure and prior traumatic event exposure and were significantly more likely to meet DSM-IV criteria for posttraumatic stress disorder (PTSD) and major depression (MDD) post-typhoon compared with persons reporting no history of panic attacks. Pre and post-typhoon panic exhibited similar patterns across variables and both panic conditions were associated with the development of PTSD and MDD, suggesting that persons experiencing panic attacks may represent a vulnerable population in need of early intervention services.

Introduction. Cerebral blood flow has been well studied in patients with panic disorder, but only few studies analyzed the mechanisms underlying the onset of a panic attack. The aim of the present study was to monitor the cerebral hemodynamics modifications during a panic attack. Materials and Methods. 10 panic disorder patients with recent onset, fully drug naïve, were compared to 13 patients with panic disorder with a previous history of treatment and to 14 controls. A continuous bilateral monitoring of mean flow velocities in right and left middle cerebral arteries was performed by transcranial Doppler. Clomipramine was chosen as challenge. Results. Eight out of 10 patients drug naïve and 6 control subjects out of 13 had a full blown panic attack during the test, whereas none of the patients with a history of treatment panicked. The occurrence of a panic attack was accompanied by a rapid decrease of flow velocities in both right and left middle cerebral arteries. Discussion. The bilateral acute decrease of mean flow velocity during a panic attack suggests the vasoconstriction of the microcirculation of deep brain structures perfused by middle cerebral arteries and involved in the so-called "fear circuitry," thus suggesting that cerebral homeostatic dysfunctions seem to have a key role in the onset of a panic attack.

Chest pain is often seen alongside with panic attacks. Moreover, panic disorder has been suggested as a risk factor for cardiovascular disease and even a trigger for acute coronary syndrome. Patients with coronary artery disease may have myocardial ischemia in response to mental stress, in which panic attack is a strong component, by an increase in coronary vasomotor tone or sympathetic hyperactivity setting off an increase in myocardial oxygen consumption. Indeed, coronary artery spasm was presumed to be present in cases of cardiac ischemia linked to panic disorder. These findings correlating panic disorder with coronary artery disease lead us to raise questions about the favorable prognosis of chest pain in panic attack. To investigate whether myocardial ischemia is the genesis of chest pain in panic attacks, we developed a myocardial perfusion study through research by myocardial scintigraphy in patients with panic attacks induced in the laboratory by inhalation of 35% carbon dioxide. In conclusion, from the data obtained, some hypotheses are discussed from the viewpoint of endothelial dysfunction and microvascular disease present in mental stress response.

Human influenza is a contagious respiratory illness caused by the influenza virus. The influenza vaccination is recommended annually, but several adverse effects related to allergic reactions have been reported. Panic attacks are also known to occur, but no case of a panic attack adverse effect has been reported in South Korea. We present two cases of panic disorder patients whose symptoms were aggravated by the influenza vaccination. We assumed that dysregulation of T-lymphocytes in panic disorder patients could have a role in activating various kinds of cytokines and chemokines, which then can lead to panic attack aggravation.

Evaluating emotional sensitivity and tolerance factors in the prediction of panic-relevant responding to a biological challenge.

2010-01-01

The current study investigated anxiety sensitivity, distress tolerance (Simons & Gaher, 2005), and discomfort intolerance (Schmidt, Richey, Cromer, & Buckner, 2007) in relation to panic-relevant responding (i.e., panic attack symptoms and panic-relevant cognitions) to a 10% carbon dioxide enriched air challenge. Participants were 216 adults (52.6% female; M(age)=22.4, SD=9.0). A series of hierarchical multiple regressions was conducted with covariates of negative affectivity and past year panic attack history in step one of the model, and anxiety sensitivity, discomfort intolerance, and distress tolerance entered simultaneously into step two. Results indicated that anxiety sensitivity, but not distress tolerance or discomfort intolerance, was significantly incrementally predictive of physical panic attack symptoms and cognitive panic attack symptoms. Additionally, anxiety sensitivity was significantly predictive of variance in panic attack status during the challenge. These findings emphasize the important, unique role of anxiety sensitivity in predicting risk for panic psychopathology, even when considered in the context of other theoretically relevant emotion vulnerability variables.

Panic Attack History and Smoking Topography

Background Little is known about panic attacks and puffing topography, a behavioral index of the value of smoking reinforcement. This study examined smoking style during the course of smoking of a single cigarette among adult daily smokers with and without a history of panic attacks. Method Participants (n = 124, Mage = 43.9, SD = 9.7; 44.4% female) were non-treatment seeking daily smokers. Lifetime panic attack history was assessed via diagnostic assessment; 28.2% (n = 35) of the sample had a panic attack history. Participants smoked one cigarette during an ad libitum smoking trial. Puff volume, duration, and inter-puff interval were measured using the Clinical Research Support System (CReSS) pocket device. Results Regression analyses revealed that panic attack status was not associated with significant differences in average puff volume, duration, or inter-puff interval. Multi-level modeling was used to examine puffing trajectories. Puff-level data revealed that there was a significant quadratic time x panic effect for puff volume and duration. Those with a panic attack history demonstrated relatively sustained levels of both puff volume and duration over time, whereas those without a history of panic attacks demonstrated an increase followed by a decrease in volume and duration over time. These effects were not accounted for by the presence of general psychopathology. Discussion Smokers with a panic attack history demonstrate more persistent efforts to self-regulate the delivery of nicotine, and thus may be at risk for continued smoking and dependence. Tailored treatment may be needed to address unique vulnerabilities among this group. PMID:28033542

To study phenomenology of attacks of atrial fibrillation (AF) and to compare it with phenomenology of panic attacks for elucidation of pathogenesis of atrial fibrillation and for elaboration of rational therapeutic intervention including those aimed at correction of psychovegetative abnormalities. Patients with nonrheumatic paroxysmal AF (n=105) and 100 patients with panic attacks (n=100). Clinical, cardiological and neurological examination, analysis of patients complaints during attacks of AF, and comparison them with diagnostic criteria for panic attack. It was found that clinical picture of attacks of AF comprised vegetative, emotional and functional neurological phenomena similar to those characteristic for panic attacks. This similarity as well as positive therapeutic effect of clonazepam allowed to propose a novel pathogenic mechanism of AF attacks. Severity of psychovegetative disorders during paroxysm of AF could be evaluated by calculation of psychovegetative iudex: Psychovegetative index should be used for detection of panic attack-like component in clinical picture of AF paroxysm and thus for determination of indications for inclusion of vegetotropic drugs, e. g. clonazepam, in complex preventive therapy.

The aim of this naturalistic study was to evaluate the impact of the duration of untreated illness (DUI) on the outcome and treatment response of panic disorder (PD). Ninety-six outpatients with PD who underwent an 8-week open-label treatment with serotonergic antidepressants were subdivided into two subgroups: those with DUI 1 year. The main baseline demographic and clinical variables were calculated and compared between the two subgroups of patients (chi-square test or t-test for independent samples). The effect of the antipanic medication was evaluated by analysis of variance with repeated measures considering Hamilton Rating Scale for Anxiety, Clinical Global Impression rating scores, and the number of panic attacks/week as the dependent variables (outcome measures), while the subgroups were the independent ones. Comorbidity with onset later than PD was also considered. There were no differences between patients with DUI 1 year with respect to the outcome measures considered. However, patients with DUI > 1 year (N = 64) had a higher frequency of comorbid major depressive disorder (MDD) with onset later than PD (p = 0.006). Results from this study suggest that the DUI may be a predictor of the development of comorbid MDD in PD. Further investigations on larger samples and with longer follow-up are warranted.

Although comorbid panic disorder is associated with more severe symptoms and poorer therapeutic response in depressive patients, the relationship between panic disorder and risk of suicide attempt has not been confirmed. This study aimed to examine the relationship between comorbid panic disorder and clinical characteristics associated with suicidal risk as well as the likelihood of suicide attempt. A total of 223 outpatients with current major depressive disorder participated in the study. Both subjects with panic disorder (33%) and those without panic disorder (67%) were compared based on history of suicide attempts, current psychopathologies, and traits of impulsivity and anger. Subjects with panic disorder had higher levels of impulsivity, depression, and hopelessness and were more likely to report a history of suicide attempts. Subjects with panic disorder were younger at the time of first suicide attempt than those without panic disorder. Logistic regression analyses indicated that comorbid panic disorder was significantly associated with a history of suicide attempts after adjusting for other clinical correlates (odds ratio = 2.8; p < 0.01). These findings suggest that comorbid panic disorder in patients with major depressive disorder may be associated with a more severe burden of illness and may independently increase the likelihood of suicide attempt.

The longitudinal course and outcome of panic disorder.

PubMed

Pollack, M H; Smoller, J W

1995-12-01

Converging lines of evidence from a variety of methods of inquiry support a developmental model for panic disorder that includes a constitutional predisposition for anxiety influenced by genetic, familial, cognitive-behavioral and psychosocial factors, early expression during childhood, and variable manifestations during the life-cycle. Studies of patients followed up after acute pharmacotherapy trials and those treated naturalistically are consistent with this model and portray panic disorder as a generally chronic condition with a longitudinal course marked by relatively brief intervals of remission and high rates of recurrence and relapse. Longitudinal and follow-up studies suggest that panic attack frequency responds more readily and rapidly to pharmacotherapy than do other aspects of panic disorder such as agoraphobia and generalized anxiety. In general, the presence of agoraphobia is associated with more severe symptoms, greater chronicity, and more limited response to treatment. Other variables associated with chronicity and treatment resistance include patient-related factors (psychiatric and medical comorbidity, anxiety sensitivity) and pharmacologic factors (adequacy of dose, duration, and compliance). Although it is currently difficult to predict the duration of treatment needed for an individual patient, available evidence suggests that a substantial proportion of patients may require chronic treatment for panic disorder.

Panic attacks and hoarding disorder: an initial investigation.

2014-08-01

Panic attacks (PAs) defined as a discrete period of intense fear or discomfort, occur in the context of numerous anxiety and mood related disorders. Research has suggested that PAs serve as a significant indicator and prognostic factor for overall symptom severity, course, and comorbidity within various conditions. Consequently, a PA specifier is now applicable to all DSM-5 disorders. Despite these clinical and nosological implications, no research to date has examined associations between PAs and hoarding disorder. The current investigation evaluated relationships between PA endorsement and hoarding severity within a sample of 32 patients with hoarding disorder. Findings suggested a high rate of panic history among those with hoarding disorder (56%). Hoarders with co-occurring PAs, compared to those without PAs, evidenced significantly higher symptom severity. Moreover, PAs continued to significantly predict hoarding severity even after controlling for relevant covariates. When examining the specific relationships among PAs and hoarding symptoms (i.e., acquiring, difficulty discarding, and clutter), the endorsement of PAs was associated with increased acquiring and difficulty discarding symptoms. These findings add considerably to a growing body of literature on hoarding disorder. Implications for the assessment and treatment of PAs that co-occur with hoarding disorder are discussed.

This article examines a clinical sample of 66 Dominican and Puerto Rican subjects who reported ataques de nervios and also psychiatric disorder, and disentangles the phenomenological experiences of ataque de nervios, panic attacks, and panic disorder. In-depth cultural interviews assessed the symptomatic phenomenology of ataque episodes from the local perspective as well as in terms of key panic features, such as recurrence, rapid peaking of symptoms, and lack of provocation. Independent diagnostic assessments of panic attacks and disorder were also used to establish the phenomenological overlap between ataque and panic. Our findings indicate that 36 percent of ataques de nervios fulfill criteria for panic attacks and between 17 percent and 33 percent for panic disorder, depending on the overlap method used. The main features distinguishing ataques that fulfill panic criteria from ataques that do not include whether the episodes were provoked by an upsetting event in the person's life and the rapidity of crescendo of the actual attack. A key finding is that ataques often share individual phenomenological features with panic episodes, but that these features usually do not "run together" during the ataque experience. This confirms previous findings that ataque is a more inclusive construct than panic disorder. The importance of these findings for the clinical diagnosis and treatment of persons with ataques is discussed.

Background Spontaneous or unexpected panic attacks, per definition, occur out-of-the blue, in absence of cues or triggers. Accordingly, physiological arousal or instability should occur at the onset of or during the attack, but not preceding it. To test this hypothesisweexaminedif points of significant autonomic changes preceded the onset of spontaneous panic attacks. Methods Forty-three panic disorder patients underwent repeated 24-hour ambulatory monitoring. Thirteen naturally panic attacks were recorded during 1,960 hours of monitoring. Minute-by-minute epochs beginning 60 minutes before, and continuing to 10 minutes after, the onset of individual attacks were examined for respiration, heart rate, and skin conductance level. Measures were controlled for physical activity and vocalization, and compared to time matched control periods within the same person. Results Significant patterns of instability across a numberof autonomic and respiratory variables were detected as early as 47 minutes before panic onset. The final minutes prior to onset were dominated by respiratory changes, with significant decreases in tidal volume followed by abrupt PCO2 increases. Panic attack onset was characterized by heart rate and tidal volume increases and a drop in PCO2. Symptom report was consistent with these changes. Skin conductance levels were generally elevated in the hour before and duringthe attacks. Changes in the matched control periods were largely absent. Conclusions Significant autonomic irregularities preceded the onset of attacks that were reported as abrupt and unexpected. The findings invite reconsideration of the current diagnostic distinction betweenuncuedand cued panic attacks. PMID:21783179

Development of mental health first aid guidelines for panic attacks: a Delphi study.

Panic attacks are common, and while they are not life-threatening events, they can lead to the development of panic disorder and agoraphobia. Appropriate help at the time that a panic attack occurs may decrease the fear associated with the attack and reduce the risk of developing an anxiety disorder. However, few people have the knowledge and skills required to assist. Simple first aid guidelines may help members of the public to offer help to people who experience panic attacks. The Delphi method was used to reach consensus in a panel of experts. Experts included 50 professionals and 6 people who had experience of panic attacks and were active in mental health advocacy. Statements about how to assist someone who is having a panic attack were sourced through a systematic search of both professional and lay literature. These statements were rated for importance as first aid guidelines by the expert and consumer panels and guidelines were written using the items most consistently endorsed. Of 144 statements presented to the panels, 27 were accepted. These statements were used to develop the guidelines appended to this paper. There are a number of actions which are considered to be useful for members of the public to do if they encounter someone who is having a panic attack. These guidelines will be useful in revision of curricula of mental health first aid programs. They can also be used by members of the public who want immediate information about how to assist someone who is experiencing panic attacks.

Olfactory-triggered panic attacks among Khmer refugees: a contextual approach.

PubMed

Hinton, Devon; Pich, Vuth; Chhean, Dara; Pollack, Mark

2004-06-01

One hundred Khmer refugees attending a psychiatric clinic were surveyed to determine the prevalence of olfactory-triggered panic attacks as well as certain characteristics of the episodes, including trigger (i.e. type of odor), frequency, length, somatic symptoms, and the rate of associated flashbacks and catastrophic cognitions. Forty-five of the 100 patients had experienced an olfactory-triggered panic attack in the last month. Trauma associations and catastrophic cognitions (e.g. fears of a 'wind attack', 'weakness', and 'weak heart') were common during events of olfactory panic. Several case examples are presented. A multifactorial model of the generation of olfactory panic is adduced. The therapeutic implications of this model for the treatment of olfactory panic are discussed.

Controversy surrounds the questions whether co-occurring depression has negative effects on cognitive-behavioral therapy (CBT) outcomes in patients with panic disorder (PD) and agoraphobia (AG) and whether treatment for PD and AG (PD/AG) also reduces depressive symptomatology. Post-hoc analyses of randomized clinical trial data of 369 outpatients with primary PD/AG (DSM-IV-TR criteria) treated with a 12-session manualized CBT (n = 301) and a waitlist control group (n = 68). Patients with comorbid depression (DSM-IV-TR major depression, dysthymia, or both: 43.2% CBT, 42.7% controls) were compared to patients without depression regarding anxiety and depression outcomes (Clinical Global Impression Scale [CGI], Hamilton Anxiety Rating Scale [HAM-A], number of panic attacks, Mobility Inventory [MI], Panic and Agoraphobia Scale, Beck Depression Inventory) at post-treatment and follow-up (categorical). Further, the role of severity of depressive symptoms on anxiety/depression outcome measures was examined (dimensional). Comorbid depression did not have a significant overall effect on anxiety outcomes at post-treatment and follow-up, except for slightly diminished post-treatment effect sizes for clinician-rated CGI (p = 0.03) and HAM-A (p = 0.008) when adjusting for baseline anxiety severity. In the dimensional model, higher baseline depression scores were associated with lower effect sizes at post-treatment (except for MI), but not at follow-up (except for HAM-A). Depressive symptoms improved irrespective of the presence of depression. Exposure-based CBT for primary PD/AG effectively reduces anxiety and depressive symptoms, irrespective of comorbid depression or depressive symptomatology. Copyright © 2012 S. Karger AG, Basel.

To study the effect of playing cell phone chess game on treating panic attack. The chess game on an android cell phone was played by the researcher who was affected by panic attack as a post-traumatic disorder immediately after or before feeling of the start of symptoms. The right level of difficulty, i.e., levels 2-4, was selected for optimal results. Playing chess game on the android cell phone prevented the manifestation of panic attack and led to the cure of this traumatic condition. Chess therapy with the right level of difficulty can be recommended as a very effective non-pharmaceutical method for the successful treatment of panic attacks. Copyright © 2017 Elsevier B.V.

The current study investigated the main and interactive effects of a nonclinical panic attack history and distress tolerance in relation to PTSD symptoms. The sample consisted of 91 adults (62.6% women; M(age)=23.45, SD=9.56) who met DSM-IV criteria for trauma exposure, 53.8% of whom met criteria for a recent (past 2 years) history of nonclinical panic attacks. Results indicated that distress tolerance, as measured by the Distress Tolerance Scale (Simons & Gaher, 2005), was significantly related to all PTSD symptom clusters, and a nonclinical panic attack history was significantly related to PTSD re-experiencing and hyperarousal symptoms. The interaction of a nonclinical panic attack history and distress tolerance significantly predicted unique variance in only PTSD hyperarousal symptoms. Implications and future directions are discussed for the role of nonclinical panic attacks and distress tolerance in PTSD symptom expression. Copyright © 2010 Elsevier Ltd. All rights reserved.

Panic disorder and subthreshold panic in the UK general population: epidemiology, comorbidity and functional limitation.

2011-09-01

The epidemiology of panic disorder has not been investigated in the past in the UK using a nationally representative sample of the population. The aim of the present paper was to examine the epidemiology, comorbidity and functional impairment of subthreshold panic and panic disorder with or without agoraphobia. We used data from the 2000 Office for National Statistics Psychiatric Morbidity survey (N=8580). Panic disorder and agoraphobia were assessed with the Revised Clinical Interview Schedule (CIS-R). The prevalence of panic disorder with or without agoraphobia was 1.70% (95% confidence interval: 1.41-2.03%). Subthreshold panic was more common. Economic inactivity was consistently associated with all syndromes. The comorbidity pattern of the panic syndromes and the associated functional impairment show that panic-related conditions are important public health problems, even in subthreshold status. The findings show that efforts to reduce the disability associated with psychiatric disorders should include detection and management of panic disorder. Copyright © 2010 Elsevier Masson SAS.

Translational approach to the pathophysiology of panic disorder: Focus on serotonin and endogenous opioids.

PubMed

Graeff, Frederico G

2017-05-01

Panic patients experience recurrent panic attacks. Two main neurochemical hypotheses have been proposed to explain this vulnerability. The first suggests that panic patients have deficient serotonergic inhibition of neurons localized in the dorsal periaqueductal gray matter of the midbrain that organizes defensive reactions to cope with proximal threats as well as of sympathomotor control areas of the rostral ventrolateral medulla that generate neurovegetative symptoms of the panic attack. The second proposes that endogenous opioids buffer panic attacks in normal subjects, and their deficit results in heightened sensitivity to suffocation and separation anxiety in panic patients. Experimental results obtained in rat models of panic indicate that serotonin interacts synergistically with endogenous opioids in the dorsal periaqueductal gray through 5-HT1A and μ-opioid receptors to inhibit proximal defense and, supposedly, panic attacks. These findings allow reconciliation of the serotonergic and opioidergic hypotheses of panic pathophysiology. They also indicate that endogenous opioids are likely to participate in the panicolytic action of antidepressants and suggest that exogenous opioids may be useful for treating panic patients resistant to conventional pharmacotherapy.

Objective Little is known about factors associated with smoking cessation in cancer patients. This study examined the impact of panic attacks on smoking abstinence likelihood among cancer patients receiving tobacco cessation treatment. Method The relationship of panic attacks to 7-day point-prevalence abstinence at mid-treatment, end of treatment, and 6-month post-end of treatment were examined among cancer patients (N = 2,255 patients; 50.1% female; Mage = 54.9, SD = 11.0) who received counseling and pharmacotherapy for smoking cessation. Panic attack history indexed by two questions from the Patient Health Questionnaire (PHQ). Post-prevalence abstinence was assessed via the Timeline Follow-Back. Results Cancer patients with a history of panic attacks, (n = 493, 21.9%) relative to those without, were less likely to be abstinent at mid-treatment (OR = 0.79, CI95% = 0.64–0.98) and end of treatment (OR = 0.72, CI95% = 0.58–0.89). After adjusting for significant covariates, panic attack history remained predictive of decreased abstinence likelihood at end of treatment (OR = 0.78, CI95% = 0.62–0.99). Conclusions Panic attacks may be related to poorer cessation outcome during smoking treatment among cancer patients, and may be usefully assessed and targeted for intervention. PMID:27235990

Our aim was to observe if patients with panic disorder (PD) and patients with major depression with panic attacks (MDP) (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) respond in a similar way to the induction of panic attacks by an oral caffeine challenge test. We randomly selected 29 patients with PD, 27 with MDP, 25 with major depression without panic attacks (MD), and 28 healthy volunteers. The patients had no psychotropic drug for at least a 4-week period. In a randomized double-blind experiment performed in 2 occasions 7 days apart, 480 mg caffeine and a caffeine-free (placebo) solution were administered in a coffee form and anxiety scales were applied before and after each test. A total of 58.6% (n = 17) of patients with PD, 44.4% (n = 12) of patients with MDP, 12.0% (n = 3) of patients with MD, and 7.1% (n= 2) of control subjects had a panic attack after the 480-mg caffeine challenge test (chi(2)(3) = 16.22, P = .001). The patients with PD and MDP were more sensitive to caffeine than were patients with MD and healthy volunteers. No panic attack was observed after the caffeine-free solution intake. The patients with MD had a lower heart rate response to the test than all the other groups (2-way analysis of variance, group by time interaction with Greenhouse-Geisser correction: F(3,762) = 2.85, P = .026). Our data suggest that there is an association between panic attacks, no matter if associated with PD or MDP, and hyperreactivity to an oral caffeine challenge test.

Panic disorder: a different perspective.

PubMed

Ranganathan, A; Beitman, B D

1998-02-01

Panic disorder is a chronic and debilitating illness. In this article, we present an algorithm of the diagnosis and treatment of the illness. We place much importance upon the patient variables associated with the treatment decisions. We emphasize strong patient involvement in treatment as a way to become panic free and improve level of functioning. Panic disorder is defined in DSM-IV1 as "The presence of recurrent panic attacks followed by at least one month of persistent concern about having another panic attack, worry about the possible implications or consequences of the panic attack, or a significant behavioral change related to the attacks." A panic attack is defined as "a discrete period of intense fear or discomfort, in which four or more of the following symptoms developed abruptly and reached a peak within 10 minutes." 1) Palpitations, pounding heart or accelerated heart rate; 2) sweating; 3) trembling or shaking; 4) sensations of shortness of breath or smothering; 5) feeling of choking; 6) chest pain or discomfort; 7) nausea or abdominal distress; 8) feeling dizzy, unsteady, light-headed or faint; 9) derealization or depersonalization; 10) fear of losing control or going crazy; 11) fear of dying; 12) paresthesias; 13) chills or hot flashes. The following hypotheses have been used to conceptualize panic disorder from a psychiatrist's perspective.

Panic disorder and agoraphobia: A direct comparison of their multivariate comorbidity patterns.

PubMed

Greene, Ashley L; Eaton, Nicholas R

2016-01-15

Scientific debate has long surrounded whether agoraphobia is a severe consequence of panic disorder or a frequently comorbid diagnosis. Multivariate comorbidity investigations typically treat these diagnoses as fungible in structural models, assuming both are manifestations of the fear-subfactor in the internalizing-externalizing model. No studies have directly compared these disorders' multivariate associations, which could clarify their conceptualization in classification and comorbidity research. In a nationally representative sample (N=43,093), we examined the multivariate comorbidity of panic disorder (1) without agoraphobia, (2) with agoraphobia, and (3) regardless of agoraphobia; and (4) agoraphobia without panic. We conducted exploratory and confirmatory factor analyses of these and 10 other lifetime DSM-IV diagnoses in a nationally representative sample (N=43,093). Differing bivariate and multivariate relations were found. Panic disorder without agoraphobia was largely a distress disorder, related to emotional disorders. Agoraphobia without panic was largely a fear disorder, related to phobias. When considered jointly, concomitant agoraphobia and panic was a fear disorder, and when panic was assessed without regard to agoraphobia (some individuals had agoraphobia while others did not) it was a mixed distress and fear disorder. Diagnoses were obtained from comprehensively trained lay interviewers, not clinicians and analyses used DSM-IV diagnoses (rather than DSM-5). These findings support the conceptualization of agoraphobia as a distinct diagnostic entity and the independent classification of both disorders in DSM-5, suggesting future multivariate comorbidity studies should not assume various panic/agoraphobia diagnoses are invariably fear disorders.

The current study examined the relationship between cigarette smoking (daily) and risk of onset and persistence of panic attacks over a 10-year period among adults in mid-adulthood in the United States and whether quitting smoking reduced the risk for panic attacks. Data were drawn from the Midlife Development in the United States Survey (N = 2,101), a nationally representative sample of adults aged 25 to 74 years at baseline (wave 1, 1994-1995) who were followed up 10 years later at wave 2 (2004-2006). Psychiatric diagnoses were based on the Composite International Diagnostic Interview Short-Form (CIDI-SF [based on DSM-III-R criteria]) scales. Logistic regressions were used to evaluate the associations between smoking status and the onset and persistence of panic attack after controlling for demographic characteristics and substance use problems. Daily smoking in 1994 (OR = 1.9 [95% CI, 1.1-3.3]) and persistent daily smoking in 1994 and 2005 (OR = 2.6 [95% CI, 1.4-4.8]) were associated with a significantly increased likelihood of panic attacks in 2005. Moreover, smoking abstinence significantly reduced the risk of new-onset panic attacks (OR = 0.6 [95% CI, 0.4-0.97]) and persistence of panic attacks (OR = 0.2 [95% CI, 0.1-0.5]). The present data provide novel evidence that smoking is associated with an increased risk of panic attacks and that quitting smoking helps reduce such risk. © Copyright 2016 Physicians Postgraduate Press, Inc.

Panic disorder among Vietnamese refugees attending a psychiatric clinic: Prevalence and subtypes

2009-01-01

This study surveys Vietnamese refugees attending two psychiatric clinics to determine both the prevalence of panic disorder (PD) as well as panic attack subtypes in those suffering PD. A culturally valid adaptation of the SCID-panic module (the Vietnamese Panic Disorder Survey or VPDS) was administered to 100 Vietnamese refugees attending two psychiatric clinics. Utilizing culturally sensitive panic probes, the VPDS provides information regarding both the presence of PD and panic attack subtypes during the month prior to interview. Of 100 patients surveyed, 50 (50%) currently suffered PD. Among the 50 patients suffering PD, the most common panic attack subtypes during the previous month were the following: “orthostatic dizziness” (74% of the 50 panic disorder patients [PDPs]), headache (50% of PDPs), wind-induced/temperature-shift-induced (24% of PDPs), effort-induced (18% of PDPs), gastro-intestinal (16% of PDPs), micturition-induced (8% of PDPs), out-of-the-blue palpitations (24% of PDPs), and out-of-the-blue shortness of breath (16% of PDPs). Five mechanisms are adduced to account for this high PD prevalence as well as the specific profile of subtypes: 1) a trauma-caused panic attack diathesis; 2) trauma-event cues; 3) ethnic differences in physiology; 4) catastrophic cognitions generated by cultural syndromes; and 5) a modification of Clark’s spiral of panic.

Factors influencing care seeking for a self-defined worst panic attack.

PubMed

Katerndahl, David A

2002-04-01

Only 60 percent of persons who experience panic attacks seek treatment for them, many at the emergency department. The author documented care-seeking behaviors among persons living in the community who had experienced panic attacks and studied determinants of care seeking. In-depth structured interviews were conducted with 97 randomly selected community-dwelling adults who met DSM-III-R criteria for panic attacks. Participants were asked whether they had contemplated using or had actually used medical, alternative, and family sources of care when they had experienced their worst attack. Seventy-seven participants (79 percent) had considered using a general medical or mental health site when they experienced their worst attack. Of these, 50 (52 percent) had actually used such a site. General medical sites were contemplated more often (72 percent of participants) than mental health sites (27 percent), particularly emergency departments (43 percent) and family physicians' offices (34 percent). Other sources, such as friends or family members, alternative sites, and self-treatment, were contemplated less often. Once contemplated, certain sources were readily used, such as ambulances, family members, and self-treatment. Several factors were significantly associated with whether a person contemplated seeking care: access or barriers to treatment, perception of symptoms and of the reasons for the panic attack, and family-related variables. Contemplation and use of a mental health site after a panic attack was rare among the participants in this study. Further study of determinants of care seeking may help explain why persons who experience panic attacks fail to seek treatment or seek treatment from non-mental health sources.

Acid–base dysregulation and chemosensory mechanisms in panic disorder: a translational update

PubMed Central

Vollmer, L L; Strawn, J R; Sah, R

2015-01-01

Panic disorder (PD), a complex anxiety disorder characterized by recurrent panic attacks, represents a poorly understood psychiatric condition which is associated with significant morbidity and an increased risk of suicide attempts and completed suicide. Recently however, neuroimaging and panic provocation challenge studies have provided insights into the pathoetiology of panic phenomena and have begun to elucidate potential neural mechanisms that may underlie panic attacks. In this regard, accumulating evidence suggests that acidosis may be a contributing factor in induction of panic. Challenge studies in patients with PD reveal that panic attacks may be reliably provoked by agents that lead to acid–base dysbalance such as CO2 inhalation and sodium lactate infusion. Chemosensory mechanisms that translate pH into panic-relevant fear, autonomic, and respiratory responses are therefore of high relevance to the understanding of panic pathophysiology. Herein, we provide a current update on clinical and preclinical studies supporting how acid–base imbalance and diverse chemosensory mechanisms may be associated with PD and discuss future implications of these findings.

Background. Esophagogastroduodenoscopy (EGD) and colonoscopy (CS) can evoke anxiety, embarrassment, and discomfort. These concerns can culminate in panic attacks, which may traumatize patients and significantly decrease their compliance to the procedure. The objective of this study was to evaluate the relationship between preendoscopic anxiety and the possibility of a panic attack during an elective gastrointestinal endoscopy (EGE). Methods. The study population comprised of 79 Greek outpatients. The examination was carried out without the use of conscious sedation. Patients' anxiety levels were assessed before the procedure using the Greek version of the Spielberger State-Trait Anxiety Inventory (STAI-Y). Results. Seventy-nine patients were enrolled: 45 EGD and 34 CS. Females had higher state and trait anxiety levels than males (48.14 ± 7.94 versus 44.17 ± 7.43, P < 0.05; and 43.68 ± 6.95 versus 39.86 ± 7.46, P < 0.05). Patients who experienced panic attack had significantly higher levels of both trait and state anxiety, compared to those who were panic-free. There was no significant relationship between panic attacks and sex or type of procedure. Conclusions. Patients who experience panic attacks during endoscopic procedures appear to have significantly higher anxiety levels before the procedure. Administering the STAI questionnaire prior to the endoscopy seems to be a useful screening method for vulnerable patients.

Our aim was to compare the demographic and psychopathological features of panic disorder (PD) patients who underwent hyperventilation and breath-holding challenge tests, and to describe the features of patients who had a panic attack after both tests versus those patients who did not experience panic after either test. Eighty-five PD patients were induced to hyperventilate (30 breaths/min) for 4 min, and a week later to hold their breath for as long as possible four times with a 2-min interval in between. Anxiety scales were applied before and after the tests. Patients who responded with a panic attack to both tests (BPA, n = 25) were compared with patients who experienced spontaneous panic attacks but did not panic in response to the two tests (NPA, n = 16). The BPA group had a significantly higher presence of respiratory symptoms during a panic attack. The criteria for the respiratory PD subtype were fulfilled in 18 (72.0%) BPA patients and in 6 (37.5%) NPA patients. The BPA patients had a later onset of panic disorder and a higher familial prevalence of PD. Our data suggest that there is a distinction between PD patients who were sensitive to both hyperventilation and breath-holding tests and PD patients who were not affected by the challenge tests. The panic attack may be a final common pathway for different types of stimuli, and respiratory tests may characterize different PD subgroups.

Assessing DSM-IV symptoms of panic attack in the general population: an item response analysis.

Unexpected panic attacks may represent a non-specific risk factor for future depression and anxiety disorders. The examination of panic symptoms and associated latent severity levels may lead to improvements in the identification, prevention, and treatment of panic attacks and subsequent psychopathology for 'at risk' individuals in the general population. The current study utilised item response theory to assess the DSM-IV symptoms of panic in relation to the latent severity level of the panic attack construct in a sample of 5913 respondents from the National Epidemiologic Survey on Alcohol and Related conditions. Additionally, differential item functioning (DIF) was assessed to determine if each symptom of panic targets the same level of latent severity between different sociodemographic groups (male/female, young/old). Symptoms indexing 'choking', 'fear of dying', and 'tingling/numbness' are some of the more severe symptoms of panic whilst 'heart racing', 'short of breath', 'tremble/shake', 'dizzy/faint', and 'perspire' are some of the least severe symptoms. Significant levels of DIF were detected in the 'perspire' symptom between males and females and the 'fear of dying' symptom between young and old respondents. The current study was limited to examining cross-sectional data from respondents who had experienced at least one panic attack across their lifetime. The findings of the current study provide additional information regarding panic symptoms in the general population that may enable researchers and clinicians to further refine the detection of 'at-risk' individuals who experience threshold and sub-threshold levels of panic.

Introduction Empirical work has documented a robust and consistent relation between panic attacks and smoking behavior. Theoretical models posit smokers with panic attacks may rely on smoking to help them manage chronically elevated negative affect due to uncomfortable bodily states, which may explain higher levels of nicotine dependence and quit problems. Methods The current study examined the effects of panic attack history on nicotine dependence, perceived barriers for quitting, smoking inflexibility when emotionally distressed, and expired carbon monoxide among 461 treatment-seeking smokers. A multiple mediator path model was evaluated to examine the indirect effects of negative affect and negative affect reduction motives as mediators of the panic attack-smoking relations. Results Panic attack history was indirectly related to greater levels of nicotine dependence (b=0.039, CI95%=0.008, 0.097), perceived barriers to smoking cessation (b=0.195, CI95%=0.043, 0.479), smoking inflexibility/avoidance when emotionally distressed (b=0.188, CI95%=0.041, 0.445), and higher levels of expired carbon monoxide (b=0.071, CI95%=0.010, 0.230) through the sequential effects of negative affect and negative affect smoking motives.

Empirical work has documented a robust and consistent relation between panic attacks and smoking behavior. Theoretical models posit smokers with panic attacks may rely on smoking to help them manage chronically elevated negative affect due to uncomfortable bodily states, which may explain higher levels of nicotine dependence and quit problems. The current study examined the effects of panic attack history on nicotine dependence, perceived barriers for quitting, smoking inflexibility when emotionally distressed, and expired carbon monoxide among 461 treatment-seeking smokers. A multiple mediator path model was evaluated to examine the indirect effects of negative affect and negative affect reduction motives as mediators of the panic attack-smoking relations. Panic attack history was indirectly related to greater levels of nicotine dependence (b = 0.039, CI95% = 0.008, 0.097), perceived barriers to smoking cessation (b = 0.195, CI95% = 0.043, 0.479), smoking inflexibility/avoidance when emotionally distressed (b = 0.188, CI95% = 0.041, 0.445), and higher levels of expired carbon monoxide (b = 0.071, CI95% = 0.010, 0.230) through the sequential effects of negative affect and negative affect smoking motives. The present results provide empirical support for the sequential mediating role of negative affect and smoking motives for negative affect reduction in the relation between panic attacks and a variety of smoking variables in treatment-seeking smokers. These mediating variables are likely important processes to address in smoking cessation treatment, especially in panic-vulnerable smokers.

The sympathetic nervous system has long been believed to be involved in the pathogenesis of panic disorder, but studies to date, most using peripheral venous catecholamine measurements, have yielded conflicting and equivocal results. We tested sympathetic nervous function in patients with panic disorder by using more sensitive methods. Sympathetic nervous and adrenal medullary function was measured by using direct nerve recording (clinical microneurography) and whole-body and cardiac catecholamine kinetics in 13 patients with panic disorder as defined by the DSM-IV, and 14 healthy control subjects. Measurements were made at rest, during laboratory stress (forced mental arithmetic), and, for 4 patients, during panic attacks occurring spontaneously in the laboratory setting. Muscle sympathetic activity, arterial plasma concentration of norepinephrine, and the total and cardiac norepinephrine spillover rates to plasma were similar in patients and control subjects at rest, as was whole-body epinephrine secretion. Epinephrine spillover from the heart was elevated in patients with panic disorder (P=.01). Responses to laboratory mental stress were almost identical in patient and control groups. During panic attacks, there were marked increases in epinephrine secretion and large increases in the sympathetic activity in muscle in 2 patients but smaller changes in the total norepinephrine spillover to plasma. Whole-body and regional sympathetic nervous activity are not elevated at rest in patients with panic disorder. Epinephrine is released from the heart at rest in patients with panic disorder, possibly due to loading of cardiac neuronal stores by uptake from plasma during surges of epinephrine secretion in panic attacks. Contrary to popular belief, the sympathetic nervous system is not globally activated during panic attacks.

Perievent panic attack and depression after the World Trade Center disaster: a structural equation model analysis.

Research suggests that perievent panic attacks--panic attacks in temporal proximity to traumatic events--are predictive of later mental health status, including the onset of depression. Using a community sample of New York City residents interviewed 1 year and 2 years after the World Trade Center Disaster, we estimated a structural equation model (SEM) using pre-disaster psychological status and post-disaster life events, together with psychosocial resources, to assess the relationship between perievent panic and later onset depression. Bivariate results revealed a significant association between perievent panic and both year-1 and year-2 depression. Results for the SEM, however showed that perievent panic was predictive of year-1 depression, but not year-2 depression, once potential confounders were controlled Year-2 stressors and year-2 psychosocial resources were the best predictors of year-2 depression onset. Pre-disaster psychological problems were directly implicated in year-1 depression, but not year-2 depression. We conclude that a conceptual model that includes pre- and post-disaster variables best explains the complex causal pathways between psychological status, stressor exposure, perievent panic attacks, and depression onset two years after the World Trade Center attacks.

Plenty of evidence suggests that childhood separation anxiety (CSA) predisposes the subject to adult-onset panic disorder (PD). As well, panic is frequently comorbid with both anxiety and depression. The brain mechanisms whereby CSA predisposes to PD are but completely unknown in spite of the increasing evidence that panic attacks are mediated at midbrain's dorsal periaqueductal gray matter (DPAG). Accordingly, here we examined whether the neonatal social isolation (NSI), a model of CSA, facilitates panic-like behaviors produced by electrical stimulations of DPAG of rats as adults. Eventual changes in anxiety and depression were also assessed in the elevated plus-maze (EPM) and forced-swimming test (FST) respectively. Male pups were subjected to 3-h daily isolations from post-natal day 2 (PN2) until weaning (PN21) allotting half of litters in individual boxes inside a sound-attenuated chamber (NSI, n = 26) whilst siblings (sham-isolated rats, SHAM, n = 27) and dam were moved to another box in a separate room. Non-handled controls (CTRL, n = 18) remained undisturbed with dams until weaning. As adults, rats were implanted with electrodes into the DPAG (PN60) and subjected to sessions of intracranial stimulation (PN65), EPM (PN66) and FST (PN67-PN68). Groups were compared by Fisher's exact test (stimulation sites), likelihood ratio chi-square tests (stimulus-response threshold curves) and Bonferroni's post hoc t-tests (EPM and FST), for P<0.05. Notably, DPAG-evoked panic-like responses of immobility, exophthalmus, trotting, galloping and jumping were markedly facilitated in NSI rats relative to both SHAM and CTRL groups. Conversely, anxiety and depression scores either did not change or were even reduced in neonatally-handled groups relative to CTRL, respectively. Data are the first behavioral evidence in animals that early-life separation stress produces the selective facilitation of panic-like behaviors in adulthood. Most importantly, results implicate the DPAG not only in panic attacks but also in separation-anxious children's predispositions to the late development of PD. PMID:24594924

Background Panic disorder is one of the anxiety disorders, and anxiety is associated with some locomotor activity changes such as "restlessness". However, there have been few studies on locomotor activity in panic disorder using actigraphy, although many studies on other psychiatric disorders have been reported using actigraphy. Therefore, the aim of the present study was to investigate the relationship between panic disorder and locomotor activity pattern using a wrist-worn activity monitor. In addition, an ecological momentary assessment technique was used to record panic attacks in natural settings. Methods Sixteen patients with panic disorder were asked to wear a watch-type computer as an electronic diary for recording panic attacks for two weeks. In addition, locomotor activity was measured and recorded continuously in an accelerometer equipped in the watch-type computer. Locomotor activity data were analyzed using double cosinor analysis to calculate mesor and the amplitude and acrophase of each of the circadian rhythm and 12-hour harmonic component. Correlations between panic disorder symptoms and locomotor activity were investigated. Results There were significant positive correlations between the frequency of panic attacks and mesor calculated from double cosinor analysis of locomotor activity (r = 0.55) and between HAM-A scores and mesor calculated from double cosinor analysis of locomotor activity (r = 0.62). Conclusion Panic disorder patients with more panic attacks and more anxiety have greater objectively assessed locomotor activity, which may reflect the "restlessness" of anxiety disorders.

Panic attacks are surprisingly common in the United States, costing our economy more than $100 million per year in disability benefits and health care expenses. However, diagnosis is difficult and consequently many patients are treated for other conditions. When an underlying disorder is determined to be present, treatment of that disorder may ameliorate attacks. If none is present, panic symptoms will respond to a variety of drugs. Behavioral therapy may be necessary in severe cases or as adjunctive therapy after attacks abate.

Indolent low-grade temporal lobe tumors may present with ictal panic that may be difficult to differentiate from psychogenic panic attacks. The current study aims to demonstrate the differences between the two disorders and help physicians generate a diagnostic paradigm. This was a retrospective study of 43 patients who underwent a temporal lobectomy between 1981 and 2008 for the treatment of intractable temporal lobe epilepsy secondary to low-grade neoplasms at Rush University Medical Center. A total of 10 patients in this group presented with ictal panic who were previously being treated for psychogenic panic attacks. Medical records were reviewed for age at seizure onset, duration of symptoms, lateralization of the epileptogenic zone, pathological diagnosis, and postsurgical seizure outcome according to the modified Engel classification. Neuropathologic findings of the 10 tumors were pleomorphic xanthoastrocytoma, ganglioglioma, oligodendroglioma, and dysembryoplastic neuroepithelial. The mean age of the patients undergoing surgery was 28 years (range, 15-49). The mean duration of panic symptoms prior to surgery was 9.8 years (range, 3-23). All patients had unprovoked ictal panic. None had symptoms suggestive of a brain tumor, such as signs of increased intracranial pressure or any focal neurologic deficit. In 5 of the patients, other symptoms associated with the ictal panic, including unusual sounds, nausea, automatism, uprising gastric sensation, and déjà vu were identified. Gross total resection of the lesion resulted in improved seizure outcome in all patients undergoing surgery. Patient follow-up was, on average, 7.4 years (range, 2-14) from time of surgery. Although similar, ictal panic from epilepsy and classic panic attacks are clinically distinguishable entities with different modalities of treatment. A careful history may help differentiate patients with ictal panic from those with psychogenic panic attacks and determine for which patients to obtain neuroimaging studies. © Copyright 2013 Physicians Postgraduate Press, Inc.

This naturalistic European multicenter study aimed to elucidate the association between major depressive disorder (MDD) and comorbid anxiety disorders. Demographic and clinical information of 1346 MDD patients were compared between those with and without concurrent anxiety disorders. The association between explanatory variables and the presence of comorbid anxiety disorders was examined using binary logistic regression analyses. 286 (21.2%) of the participants exhibited comorbid anxiety disorders, 10.8% generalized anxiety disorder (GAD), 8.3% panic disorder, 8.1% agoraphobia, and 3.3% social phobia. MDD patients with comorbid anxiety disorders were characterized by younger age (social phobia), outpatient status (agoraphobia), suicide risk (any anxiety disorder, panic disorder, agoraphobia, social phobia), higher depressive symptom severity (GAD), polypsychopharmacy (panic disorder, agoraphobia), and a higher proportion receiving augmentation treatment with benzodiazepines (any anxiety disorder, GAD, panic disorder, agoraphobia, social phobia) and pregabalin (any anxiety disorder, GAD, panic disorder). The results in terms of treatment response were conflicting (better response for panic disorder and poorer for GAD). The logistic regression analyses revealed younger age (any anxiety disorder, social phobia), outpatient status (agoraphobia), suicide risk (agoraphobia), severe depressive symptoms (any anxiety disorder, GAD, social phobia), poorer treatment response (GAD), and increased administration of benzodiazepines (any anxiety disorder, agoraphobia, social phobia) and pregabalin (any anxiety disorder, GAD, panic disorder) to be associated with comorbid anxiety disorders. Our findings suggest that the various anxiety disorders subtypes display divergent clinical characteristics and are associated with different variables. Especially comorbid GAD appears to be characterized by high symptom severity and poor treatment response. Copyright © 2017 Elsevier Ltd. All rights reserved.

Hemodynamic, ventilatory, and biochemical responses of panic patients and normal controls with sodium lactate infusion and spontaneous panic attacks.

Hemodynamic, ventilatory, and biochemical variables were measured in ten healthy adults and ten panic patients during infusion of 0.5 mol/L of sodium lactate. Physical activity, fitness level, and ambulatory electrocardiograms were also recorded. Lactate infusion doubled cardiac output, increased blood lactate levels by sixfold, and produced hypernatremia, hypocalcemia, and decreased serum bicarbonate levels in both groups but raised arterial pressure only in the patients. The patients hyperventilated before and during the infusion. Physiological responses and somatic complaints with the infusion differed little between the groups, but emotional complaints were six times more frequent among the panic patients. Eight patients but no control subjects interpreted their symptoms as a panic attack. Heart rate increased with only 14 of 31 recorded spontaneous outpatient panic attacks. Sodium lactate infusions appear to produce panic by mimicking the physiology of spontaneous panic. Treatment with cardioactive agents is not indicated in the absence of cardiopulmonary or autonomic nervous system abnormalities.

To explore the role of dorsolateral prefrontal cortex (DLPFC) stimulation in the treatment of panic disorder with comorbid depression. The present study reports findings from retrospective analysis of 13 treatment-resistant patients diagnosed with comorbid panic disorder and depression, given 20 sessions of high-frequency transcranial magnetic stimulation (rTMS) over left-DLPFC over a period of 1 month. There was a significant reduction in both the panic and depressive symptom severity, assessed by applying Panic Disorder Severity Scale (PDSS) and Hamilton Depression Rating Scale (HDRS) at baseline and after 20 sessions of rTMS. There was a 38% and 40% reduction of PDSS and HDRS scores, respectively, in the sample. The changes in PDSS and HDRS scores were not significantly correlated (ρ = -0.103, p = 0.737). High-frequency rTMS delivered at left-DLPFC may have a potential role in treatment of comorbid panic disorder and depression. Future studies done on a larger sample in a controlled environment are required to establish its role.

Hypochondriasis and panic disorder are both characterized by prevalent health anxieties and illness beliefs. Therefore, the question as to whether they represent distinct nosological entities has been raised. This study examines how clinical characteristics can be used to differentiate both disorders, taking the possibility of mixed symptomatologies (comorbidity) into account. We compared 46 patients with hypochondriasis, 45 with panic disorder, and 21 with comorbid hypochondriasis plus panic disorder. While panic patients had more comorbidity with agoraphobia, hypochondriasis was more closely associated with somatization. Patients with panic disorder were less pathological than hypochondriacal patients on all subscales of the Whiteley Index (WI) and the Illness Attitude Scales (IAS) except for illness behavior. These differences were independent of somatization. Patients with hypochondriasis plus panic had higher levels of anxiety, more somatization, more general psychopathology and a trend towards increased health care utilization. Clinicians were able to distinguish between patient groups based upon the tendency of hypochondriacal patients to demand unnecessary medical treatments. These results confirm that hypochondriasis and panic disorder are distinguishable clinical conditions, characterized by generally more psychopathology and distress in hypochondriasis.

The authors report the case of a patient arrived in psychiatric ambulatory with a panic-like symptomatology. The patient refers that the symptomatology appeared after taking sibutramine. She took it with the intent to lose weight. After the disturbance beginning, the patient interrupted the sibutramine treatment but the psychiatric symptomatology didn't regress completely. It is supposed, in the light of this new evidence and in conformity of DSM-IV criteria, the diagnosis of substance-induced anxiety disorder with panic attack. Paroxetine and alprazolam were administered to the patient, with the resolution of the anxious symptoms. After eight months the treatment was suspended, since the patient referred to be pregnant; in any case, during the pregnancy no other panic attacks occurred. After six months from the suspension of the drugs, the patient can no longer be classified as affected by panic attack according to the DSM-IV criteria.

2009-09-01

A bioterrorist attacks usually cause epidemics of panic in a targeted population. We have presented epidemiologic aspect of this phenomenon as a three-component model--host, information on an attack and social network. We have proposed a mathematical model of panic and counter-measures as the function of time in a population exposed to a bioterrorist attack. The model comprises ordinary differential equations and graphically presented combinations of the equations parameters. Clinically, we have presented a model through a sequence of psychic conditions and disorders initiated by an act of bioterrorism. This model might be helpful for an attacked community to timely and properly apply counter-measures and to minimize human mental suffering during a bioterrorist attack.

We performed a meta-analysis of all single- or double-blind, randomized controlled trials comparing alprazolam to another benzodiazepine in the treatment of adult patients meeting the Diagnostic and Statistical Manual of Mental Disorders, Third or Fourth Edition, criteria for panic disorder or agoraphobia with panic attacks. Eight studies met inclusion criteria, describing a total of at least 631 randomized patients. In the pooled results, there were no significant differences in efficacy between alprazolam and the comparator benzodiazepines on any of the prespecified outcomes: improvement in mean panic attack frequency (between-arm weighted mean difference of 0.6 panic attacks per week; 95% confidence interval [CI], -0.3 to 1.6), improvement in Hamilton Anxiety Rating Scale score (weighted mean difference of 0.8 points; 95% CI, -0.5 to 2.1), and proportion of patients free of panic attacks at the final evaluation (pooled relative risk, 1.1; 95% CI, 0.9-1.4). Statistical heterogeneity on prespecified outcomes was not eliminated by stratification on baseline anxiety level. The available evidence fails to demonstrate alprazolam as superior to other benzodiazepines for the treatment of panic disorder.

An animal model of panic vulnerability with chronic disinhibition of the dorsomedial/perifornical hypothalamus

PubMed Central

Johnson, Philip L.; Shekhar, Anantha

2013-01-01

Panic disorder (PD) is a severe anxiety disorder characterized by susceptibility to induction of panic attacks by subthreshold interoceptive stimuli such as sodium lactate infusions or hypercapnia induction. Here we review a model of panic vulnerability in rats involving chronic inhibition of GABAergic tone in the dorsomedial/ perifornical hypothalamic (DMH/PeF) region that produces enhanced anxiety and freezing responses in fearful situations, as well as a vulnerability to displaying acute panic-like increases in cardioexcitation, respiration activity and “flight” associated behavior following subthreshold interoceptive stimuli that do not elicit panic responses in control rats. This model of panic vulnerability was developed over 15 years ago and has provided an excellent preclinical model with robust face, predictive and construct validity. The model recapitulates many of the phenotypics features of panic attacks associated with human panic disorder (face validity) including greater sensitivity to panicogenic stimuli demonstrated by sudden onset of anxiety and autonomic activation following an administration of a sub-threshold (i.e., do not usually induce panic in healthy subjects) stimulus such as sodium lactate, CO2, or yohimbine. The construct validity is supported by several key findings; DMH/PeF neurons regulate behavioral and autonomic components of a normal adaptive panic response, as well as being implicated in eliciting panic-like responses in humans. Additionally, Patients with PD have deficits in central GABA activity and pharmacological restoration of central GABA activity prevents panic attacks, consistent with this model. The model’s predictive validity is demonstrated by not only showing panic responses to several panic-inducing agents that elicit panic in patients with PD, but also by the positive therapeutic responses to clinically used agents such as alprazolam and antidepressants that attenuate panic attacks in patients. More importantly, this model has been utilized to discover novel drugs such as group II metabotropic glutamate agonists and a new class of translocator protein enhancers of GABA, both of which subsequently showed anti-panic properties in clinical trials. All of these data suggest that this preparation provides a strong preclinical model of some forms of human panic disorders. PMID:22484112

The effect of ambient air pollution on panic disorder in the general population has not yet been thoroughly elucidated, although the occurrence of panic disorder in workers exposed to organic solvents has been reported previously. We investigated the association of ambient air pollution with the risk of panic attack-related emergency department visits. Using health insurance claims, we collected data from emergency department visits for panic attacks in Seoul, Republic of Korea (2005-2009). Daily air pollutant concentrations were obtained using automatic monitoring system data. We conducted a time-series study using a generalized additive model with Poisson distribution, which included spline variables (date of visit, daily mean temperature, and relative humidity) and parametric variables (daily mean air pollutant concentration, national holiday, and day of the week). In addition to single lag models (lag1 to lag3), cumulative lag models (lag0-1 to lag0-3) were constructed using moving-average concentrations on the days leading up to the visit. The risk was expressed as relative risk (RR) per one standard deviation of each air pollutant and its 95% confidence interval (95% CI). A total of 2320 emergency department visits for panic attacks were observed during the study period. The adjusted RR of panic attack-related emergency department visits was 1.051 (95% CI, 1.014-1.090) for same-day exposure to ozone. In cumulative models, adjusted RRs were 1.068 (1.029-1.107) in lag0-2 and 1.074 (1.035-1.114) in lag0-3. The ambient ozone concentration was significantly associated with emergency department visits for panic attacks. Copyright © 2015 Elsevier Ltd. All rights reserved.

Responses to false physiological feedback in individuals with panic attacks and elevated anxiety sensitivity.

Story, Tyler J; Craske, Michelle G

2008-09-01

Participants with elevated anxiety sensitivity and a history of panic attacks were compared to a low anxiety comparison group with respect to physiological and subjective reactivity to false heart-rate feedback and reactivity to a priming procedure. Whereas accurate heart-rate feedback elicited minimal responses, participants across groups showed significant physiological and subjective responses to false feedback. High risk and low risk participants did not differ in heart-rate responses to false feedback, though panic attack frequency did predict physiological and subjective reactions to false feedback in the high risk group. Self-reported nonspecific anxiety was significantly higher in high risk female participants than in low risk female participants, while males did not different in general subjective anxiety. However, high risk participants reported more panic-specific symptoms during the false feedback task than low risk participants, regardless of the sex of the participant. Therefore, although the experimental paradigm appeared to trigger nonspecific anxiety in high risk female participants, panic attack symptoms in reaction to the task were specific to risk group, not sex, and consistent with hypotheses. Surprisingly, the priming procedure did not influence physiological or subjective responses to false feedback in either group. These results raise additional questions regarding the process and impact of interception in individuals with panic attacks, and suggest that false perception of internal changes may contribute to risk for panic disorder when exposed to believable cues.

Existing literature on panic disorder (PD) yields no data regarding the differential rates of improvement during Cognitive Behavioral Therapy (CBT), Selective Serotonin Reuptake Inhibitor (SSRI) or both combined (CBT+SSRI). Patients were randomized to CBT, SSRI or CBT+SSRI which each lasted one year including three months of medication taper. Participating patients kept record of the frequency of panic attacks throughout the full year of treatment. Rate of improvement on panic frequency and the relationship between rate of improvement and baseline agoraphobia (AG) were examined. A significant decline in frequency of panic attacks was observed for each treatment modality. SSRI and CBT+SSRI were associated with a significant faster rate of improvement as compared to CBT. Gains were maintained after tapering medication. For patients with moderate or severe AG, CBT+SSRI was associated with a more rapid improvement on panic frequency as compared to patients receiving either mono-treatment. Frequency of panic attacks was not assessed beyond the full year of treatment. Second, only one process variable was used. Patients with PD respond well to each treatment as indicated by a significant decline in panic attacks. CBT is associated with a slower rate of improvement as compared to SSRI and CBT+SSRI. Discontinuation of SSRI treatment does not result in a revival of frequency of panic attacks. Our data suggest that for patients without or with only mild AG, SSRI-only will suffice. For patients with moderate or severe AG, the combined CBT+SSRI treatment is recommended. Copyright © 2013 Elsevier B.V. All rights reserved.

Ost, L G; Westling, B E

1995-02-01

The present study investigated the efficacy of a coping-technique, applied relaxation (AR) and cognitive behavior therapy (CBT), in the treatment of panic disorder. Thirty-eight outpatients fulfilling the DSM-III-R criteria for panic disorder with no (n = 30) or mild (n = 8) avoidance were assessed with independent assessor ratings, self-report scales and self-observation of panic attacks before and after treatment, and at a 1-yr follow-up. The patients were treated individually for 12 weekly sessions. The results showed that both treatments yielded very large improvements, which were maintained, or furthered at follow-up. There was no difference between AR and CBT on any measure. The proportion of panic-free patients were 65 and 74% at post-treatment, and 82 and 89% at follow-up, for AR and CBT, respectively. There were no relapses at follow-up, on the contrary 55% of the patients who still had panic attacks at post-treatment were panic-free at follow-up. Besides affecting panic attacks the treatments also yielded marked and lasting changes on generalized anxiety, depression and cognitive misinterpretations. The conclusion that can be drawn is that both AR and CBT are effective treatments for panic disorder without avoidance.

Effect of single doses of pindolol and d-fenfluramine on flumazenil-induced anxiety in panic disorder patients.

2017-11-04

The effects of the 5-HT 1A receptor blocker pindolol and the 5-HT releasing and uptake blocking agent d-fenfluramine, both used as indirect serotonin agonists, on flumazenil-induced acute anxiety reactions were studied in panic disorder patients to test the hypothesis that serotonin (5-HT) inhibits neural systems mediating panic attacks. Thirty never treated or drug free PD patients (16 females) aged 22-49 y (mean±SD, 32.9±8) received single doses of d-fenfluramine (n=10; 30mg, p.o.), pindolol (n=10; 5mg, p.o.), or placebo (n=10) 90 and 45min before a challenge test with flumazenil (1.5mg, i.v., in 10min), under double-blind conditions. Panic attacks occurred in 5 control subjects (placebo-flumazenil group), 5 subjects in the pindolol group and in 7 in the d-fenluramine pre-treated patients. Patients experiencing anxiety attacks following flumazenil reported higher increases in anxiety scores. Respiratory rate increases were not different between patients experiencing or not a panic attack. Despite sample size limitation, this study suggests that flumazenil induced anxiety reaction is not a good pharmacological model of panic attacks, considering the absence of serotonergic modulation of its effects.

To determine the nosological and phenomenological overlap and boundaries between panic disorder and hypochondriasis, we compared the symptoms, disability, comorbidity, and medical care of primary care patients with each diagnosis. Patients with DSM-III-R panic disorder were recruited by screening consecutive primary care clinic attenders and then administering a structured diagnostic interview for panic disorder. Patients also completed self-report questionnaires, and their primary care physicians completed questionnaires about them. They were then compared with patients with DSM-III-R hypochondriasis from the same setting who had been studied previously. One thousand six hundred thirty-four patients were screened; 135 (71.0% of the 190 eligible patients) completed the research battery; 100 met lifetime panic disorder criteria. Twenty-five of these had comorbid hypochondriasis. Those without comorbid hypochondriasis (n = 75) were then compared with patients with hypochondriasis without comorbid panic disorder (n = 51). Patients with panic disorder were less hypochondriacal (P < .001), somatized less (P < .05), were less disabled (P < .001), were more satisfied with their medical care (P < .001), and were rated by their physicians as less help rejecting (P < .05) and less demanding (P < .01). Major depression was more prevalent in the group with panic disorder (66.7% vs 45.1%; P < .05), as were phobias (76.0% vs 37.3%; P < .001), but somatization disorder symptoms (P < .0001) and generalized anxiety disorder were less prevalent (74.5% vs 16.0%; P < .001) in panic disorder than was hypochondriasis. While hypochondriasis and panic disorder co-occur to some extent in a primary care population, the overlap is by no means complete. These patients are phenomenologically and functionally differentiable and distinct and are viewed differently by their primary care physicians.

A hypnosis protocol for treating panic disorder is provided. The implementation of this protocol is demonstrated through a case example involving the successful treatment of a 28-year-old firefighter presenting with a 4-month history of near-daily panic attacks. Core principles associated with this protocol include: (1) Elementary education about the physiology of panic; (2) A review of primary factors contributing to the evolution and manifestation of panic; (3) Encouragement of physical activity; (4) Utilization of hypnosis applications; and (5) Monitoring and measuring progress evidenced by a reduction in the frequency and intensity of panic attacks. Six years after his last hypnosis session, "Jason," the once panicked firefighter returned to my office for concerns unrelated to panic, and reported that he remained panic-free, retained his job, and was twice promoted.

Introduction Panic-like anxiety (panic attacks with or without panic disorder), a highly treatable condition, is the most prevalent condition associated with unexplained chest pain in the emergency department. Panic-like anxiety may be responsible for a significant portion of the negative consequences of unexplained chest pain, such as functional limitations and chronicity. However, more than 92% of panic-like anxiety cases remain undiagnosed at the time of discharge from the emergency department. The 4-item Panic Screening Score (PSS) questionnaire was derived in order to increase the identification of panic-like anxiety in emergency department patients with unexplained chest pain. Methods and analysis The goals of this prospective cohort study were to (1) refine the PSS; (2) validate the revised version of the PSS; (3) measure the reliability of the revised version of the PSS and (4) assess the acceptability of the instrument among emergency physicians. Eligible and consenting patients will be administered the PSS in a large emergency department. Patients will be contacted by phone for administration of the criterion standard for panic attacks as well as by a standardised interview to collect information for other predictors of panic attacks. Multivariate analysis will be used to refine the PSS. The new version will be prospectively validated in an independent sample and inter-rater agreement will be assessed in 10% of cases. The screening instrument acceptability will be assessed with the Ottawa Acceptability of Decision Rules Instrument. Ethics and dissemination This study protocol has been reviewed and approved by the Alphonse-Desjardins research ethics committee. The results of the study will be presented in scientific conferences and published in peer-reviewed scientific journals. Further dissemination via workshops and a dedicated website is planned.

Hypochondriasis Differs From Panic Disorder and Social Phobia: Specific Processes Identified Within Patient Groups.

PubMed

Höfling, Volkmar; Weck, Florian

2017-03-01

Studies of the comorbidity of hypochondriasis have indicated high rates of cooccurrence with other anxiety disorders. In this study, the contrast among hypochondriasis, panic disorder, and social phobia was investigated using specific processes drawing on cognitive-perceptual models of hypochondriasis. Affective, behavioral, cognitive, and perceptual processes specific to hypochondriasis were assessed with 130 diagnosed participants based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria (66 with hypochondriasis, 32 with panic disorder, and 32 with social phobia). All processes specific to hypochondriasis were more intense for patients with hypochondriasis in contrast to those with panic disorder or social phobia (0.61 < d < 2.67). No differences were found between those with hypochondriasis with comorbid disorders and those without comorbid disorders. Perceptual processes were shown to best discriminate between patients with hypochondriasis and those with panic disorder.

The highly prevalent psychiatric disorders dysthymia and panic disorder have often a chronic or recurrent course with superimposed major depression. The prominent comorbidity between these diagnoses constitutes a confounding factor in the study of long-term outcome. We performed a 9-year follow-up of 38 patients with "pure" diagnoses, i.e. without comorbid dysthymia and panic disorder, selected from two 2-year naturalistic treatment studies with psychotherapy and antidepressant medication. The aims of the present study were to investigate 1) the stability of change, and 2) the impact of comorbid personality disorders (PDs) on long-term outcome. Patients were reassessed with SCID-I and SCID-II interviews, SCL-90/BSI and a detailed, modified life-charting interview, investigating course and treatment over time. About 50% of patients showed substantial improvement, of whom about half were in remission. Comorbid PD was a negative prognostic factor independently of Axis I diagnosis. Although patients with panic disorder had a lower frequency of comorbid PD, later onset, shorter duration of illness and better outcome after the original studies, there was no difference in the long-term outcome. The less stable outcome among panic patients suggests that standard treatments are not resulting in enduring remission. In order to achieve remission, it is necessary to 1) address comorbid PDs, 2) perform careful assessments of all comorbid diagnoses, and 3) build routines for the follow-up and augmentation of treatments.

Empirical research has found that panic attacks are related to increased risk of more severe nicotine withdrawal and poor cessation outcome. Anxiety sensitivity (AS; fear of anxiety and related sensations) has similarly been found to be related to an increased risk of acute nicotine withdrawal and poorer cessation outcome. However, research has yet to examine the relative contributions of panic attacks and AS in terms of cognitive-based smoking processes (e.g., negative reinforcement smoking expectancies, addictive and negative affect-based reduction smoking motives, barriers to cessation, problem symptoms experienced while quitting). Participants (n = 242; 57.4% male; M (age) = 38.1) were daily smokers recruited as a part of a larger randomized control trial for smoking cessation. It was hypothesized that both panic attacks and AS would uniquely and independently predict the studied cognitive-based smoking processes. As hypothesized, AS was uniquely and positively associated with all smoking processes after controlling for average number of cigarettes smoked per day, current Axis I diagnosis, and participant sex. However, panic attack history was only significantly related to problem symptoms experienced while quitting smoking. Although past research has demonstrated significant associations between panic attacks and certain aspects of cigarette smoking (e.g., severity of nicotine withdrawal; lower abstinence rates, and negative affect reduction motives), the present findings suggest that AS may be more relevant to understanding beliefs about and motives for smoking behavior as well as perceptions of cessation-related difficulties.

Blood B-type natriuretic peptide level increases in patients who complain shortness of breath and chest pain in the course of panic attack.

Blood pro-B-type natriuretic peptide (pro-BNP) level increases in case of myocardial ischemia and myocardial volume or pressure overload. The aim of this study is to measure changes in blood pro-BNP level during the course of panic attack with symptoms of chest pain and/or dyspnea. Patients who were admitted to the emergency room with panic attack have been regarded as the study group. Blood pro-BNP level has been measured during follow-up of the patients upon admission and 2h later. Systolic and diastolic blood pressure and pulse rate were significantly decreased (p<0.0001) during follow-up of the patients (ages between 18 and 43 years; mean 26+/-6.13 years). Paradoxically, blood pro-BNP level of patients was significantly increased during the same period (52.86+/-59.73 versus 50.97+/-57.42 U/L; p<0.0001). Blood pro-BNP level has increased among patients who have complained chest pain and/or dyspnea as symptoms of panic attack. It is thought that chest pain and dyspnea in the course of panic attack may not be purely psychological.

Our objective was to assess the prevalence of panic disorder, its influence on quality of life (QoL), and the presence of further anxiety and depressive comorbid disorders in outpatients with chronic heart failure (CHF). In a cross-sectional study, anxiety and depressive disorders were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnostic criteria in patients with CHF who were aged > or =18 years and had New York Heart Association (NYHA) Functional Classes I-IV, using the Patient Health Questionnaire. Health-related QoL was evaluated using the Short-Form 36 Health Survey (SF-36). Of the 258 participating patients, 24 (9.3%) fulfilled diagnostic criteria for panic disorder. Seven of these (29.2%) were diagnosed with comorbid anxiety disorders, 11 (47.3%) were diagnosed with comorbid depressive disorder, and 5 (20.8%) were diagnosed with other anxiety disorders and any depressive disorder. Female gender [odds ratio (OR)=3.1; 95% confidence interval (95% CI)=1.2-7.8; P=.02] and a lower level of education (OR=0.3; 95% CI=0.1-0.9; P=.04) were associated with the presence of panic disorder. In patients with panic disorder, QoL was significantly more restricted on all subscales of the SF-36 as compared to those without panic disorder, even when age, gender, and NYHA functional class were controlled for (P=.05 to <.01). Approximately 1 of 10 patients with CHF suffers from panic disorder, many of whom also have additional anxiety or depressive comorbid disorders. Female gender and a low level of education are positively associated with the presence of panic disorder. QoL is severely limited by the presence of panic disorder. Diagnosis of mental disorders and treatment offers for affected patients should be available in patient care.

Ventilatory control of heart rate during inhalation of 5% CO2 and types of panic attacks.

PubMed

Ley, R

1991-09-01

Differences in the magnitude of increases in heart rate during prolonged inhalation of 5% CO2 range from a mean of 25 b/min for a group of eight panic-disorder patients who panicked (Woods, Charney, Goodman, & Heninger, 1988. Archives of General Psychiatry, 45, 43-52) to zero b/min for 16 patients, eight of whom panicked (Craske & Barlow, 1990. Journal of Abnormal Psychology, 99, 302-307). What accounts for this disparity? The present paper describes how heart rate can be increased by means of voluntary overbreathing during prolonged inhalation of 5% CO2 in air. This suggests that differences in the degree of overbreathing may explain differences in the magnitude of increases in heart rate during inhalation of 5% CO2. An explanation is also offered for the curious finding that some patients experience "panic attacks" with zero increase in heart rate. Evidence suggests that this is likely to happen in cognitively based panic attacks, in contrast to hyperventilatory attacks or anticipatory attacks.

The clinical presentation of panic disorder and panic attack overlaps many symptoms typically experienced in coronary heart disease (CHD). Etiological links between panic disorder and CHD are controversial and remain largely tenuous. This systematic review aims to pool together data regarding panic disorder with respect to incident CHD or myocardial infarction. Electronic databases (MEDLINE, EMBASE, PsycINFO and SCOPUS) will be searched using a search strategy exploding the topics for CHD and panic disorder. Authors and reference lists of included studies will also be contacted to identify additional published and unpublished studies. Eligibility criteria are as follows: persons without CHD who meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; Comparison: persons without CHD who do not meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; verified fatal and non-fatal CHD at follow-up; including coronary revascularization procedure, coronary artery disease, and myocardial infarction. Studies adopting self-report CHD will be ineligible. Screening will be undertaken by two independent reviewers with disagreements resolved through discussion. Data extraction will include original data specified as hazard ratios, risk ratios, and original cell data if available. Risk of bias assessment will be undertaken by two independent reviewers. Meta-analytic methods will be used to synthesize the data collected relating to the CHD outcomes with Cochrane Review Manager 5.3. This systematic review aims to clarify whether panic disorder is associated with elevated risk for subsequent CHD. An evaluation of the etiological links between panic disorder with incident CHD might inform evidence-based clinical practice and policy concerning triaging chest pain patients, diagnostic assessment, and psychiatric intervention with panic disorder patients.

Depression often involves anxiety symptoms and shows a strong comorbidity with panic disorder. However, the neural basis is unclear. The aim of the current study was to use semantic priming to investigate the neural correlates of panic and anxiety-related information processing in depression. In a lexical decision task, panic/agoraphobia-disorder-related and neutral word-pairs were presented during functional magnetic resonance imaging. Participants comprised 19 patients with major depression but without comorbid anxiety and 19 demographically matched controls. On a behavioral level, comparable significant priming effects were found for the neutral condition, while only patients showed a significant inhibition effect (slower reaction time for panic-related stimuli) for the panic condition. On a neural level, significant group differences emerged in left fronto-parietal (enhanced activation for patients) and left temporo-occipital regions (reduced activation for patients). The results showed that depressed patients recruit not only areas related to the interaction of emotion and semantic processing but also regions that are related to fear circuitry to process panic-related information. Hence, in the context of depression, there seems to be a pathological processing of panic-related information that could play an important role during the disorder and should be considered.

The effect of the cognitive behavioral therapy (CBT) for panic disorder varies, but how personality disorder functioning style influences it remains unclear. In 30 healthy volunteers and 44 patients with panic disorder (22 treated and 22 waiting list), we administered the Parker Personality Measure (PERM) and the Plutchik-van Praag Depression Inventory (PVP). Before and during the CBT or waiting period, patients were asked to record their panic attacks using the Panic Attack Record (PAR). Patients scored significantly higher on PERM Antisocial, Borderline, Histrionic, Avoident, Dependent, and Passive-aggressive styles and on depression. After CBT, all PAR parameters were significantly reduced in the treated group. The Obsessive-compulsive style was positively correlated with the panic attack duration and the total-thought before CBT or waiting period in all patients. In treated patients, the decreased panic attack duration was positively correlated with Histrionic, Obsessive-compulsive and Passive-aggressive; the decreased total symptom number was positively correlated with Antisocial and Histrionic; the decreased total-sensation was positively correlated with antisocial; and the total-thought was positively correlated with Narcissistic style. The length and duration of CBT was short and mainly with behavioral strategies, how personality influenced the related cognition per se remains unknown here. However, our preliminary results indicate that personality disorder functioning styles related to the externalized behaviors and the Obsessive-compulsive style have positive effects on CBT for panic disorder, implying that CBT practitioners should note their personality styles when treating these patients.

Panic attack symptoms differentiate patients with epilepsy from those with psychogenic nonepileptic spells (PNES).

Psychogenic nonepileptic spells (PNES) are frequently challenging to differentiate from epileptic seizures. The experience of panic attack symptoms during an event may assist in distinguishing PNES from seizures secondary to epilepsy. A retrospective analysis of 354 patients diagnosed with PNES (N=224) or with epilepsy (N=130) investigated the thirteen Diagnostic and Statistical Manual-IV-Text Revision panic attack criteria endorsed by the two groups. We found a statistically higher mean number of symptoms reported by patients with PNES compared with those with epilepsy. In addition, the majority of the panic attack symptoms including heart palpitations, sweating, shortness of breath, choking feeling, chest discomfort, dizziness/unsteadiness, derealization or depersonalization, fear of dying, paresthesias, and chills or hot flashes were significantly more frequent in those with PNES. As patients with PNES frequently have poor clinical outcomes, treatment addressing the anxiety symptomatology may be beneficial. Copyright © 2014 Elsevier Inc. All rights reserved.

Neuroactive steroids modulate anxiety in experimental animals and possibly in humans. The secretion of these compounds has been found to be altered in panic disorder (PD), with such alterations having been suggested to be a possible cause or effect of panic symptomatology. Panic-like attacks can be induced in healthy individuals by administration of panicogenic agents or by physical procedures, and we have now measured the plasma concentrations of neuroactive steroids in such individuals before, during, and after panicogenic inhalation of CO2 in order to investigate whether abnormalities of neuroactive steroid secretion might contribute to the pathogenesis of PD. Fifty-nine psychologically and physically healthy subjects, including 42 women (11 in the follicular phase of the menstrual cycle, 14 in the luteal phase, and 17 taking contraceptive pills) and 17 men, who experienced a panic-like attack on previous exposure to 7% CO2 were again administered 7% CO2 for 20min. Thirty-three of these individuals (responders) again experienced a panic-like attack, whereas the remaining 26 subjects did not (nonresponders). All subjects were examined with the VAS-A and PSL-III-R scales for anxiety and panic symptomatology before and after CO2 inhalation. The plasma concentrations of progesterone, 3α,5α-tetrahydroprogesterone (3α,5α-THPROG=allopregnanolone), 3α,5α-tetrahydrodesoxycorticosterone (3α,5α-THDOC), dehydroepiandrosterone (DHEA), and cortisol were measured 15min and immediately before the onset of CO2 administration as well as immediately, 10, 30, and 50min after the end of CO2 inhalation. Neuroactive steroids were measured in the laboratory of Prof. Biggio in Cagliari, Sardinia, Italy. Neurosteroid levels did not change significantly in both responders and nonresponders before, during, or after CO2 inhalation. These data suggest that neuroactive steroid concentrations before, during, or after CO2 inhalation do not seem to correlate with panic symptomatology during panic-like attacks in subjects not affected by PD, and they therefore do not support the notion that abnormalities in neuroactive steroid secretion are either a cause or an effect of such attacks.

Feared consequences of panic attacks in panic disorder: a qualitative and quantitative analysis.

Raffa, Susan D; White, Kamila S; Barlow, David H

2004-01-01

Cognitions are hypothesized to play a central role in panic disorder (PD). Previous studies have used questionnaires to assess cognitive content, focusing on prototypical cognitions associated with PD; however, few studies have qualitatively examined cognitions associated with the feared consequences of panic attacks. The purpose of this study was to conduct a qualitative and quantitative analysis of feared consequences of panic attacks. The initial, qualitative analysis resulted in the development of 32 categories of feared consequences. The categories were derived from participant responses to a standardized, semi-structured question (n = 207). Five expert-derived categories were then utilized to quantitatively examine the relationship between cognitions and indicators of PD severity. Cognitions did not predict PD severity; however, correlational analyses indicated some predictive validity to the expert-derived categories. The qualitative analysis identified additional areas of patient-reported concern not included in previous research that may be important in the assessment and treatment of PD.

Sarcoidosis is a systemic disease of unknown etiology, in which granulomas develop in various organs, including the skin, lungs, eyes, or heart. It has been reported that patients with sarcoidosis are more likely to develop panic disorder than members of the general population. However, there are many unknown factors concerning the causal relationship between these conditions. We present the case of a 57-year-old woman who appeared to have panic disorder, as she experienced repeated panic attacks induced by transient complete atrioventricular block, associated with cardiac sarcoidosis. Psychotherapy and pharmacotherapy were not effective in the treatment of her panic attacks. However, when we implanted a permanent pacemaker and initiated steroid treatment for cardiac sarcoidosis, panic attacks were ameliorated. Based on these findings, we diagnosed the patient's symptoms as an anxiety disorder associated with cardiac sarcoidosis, rather than panic disorder. This report highlights the importance of considering cardiac sarcoidosis in the differential diagnosis of panic disorder. This cardiac disease should be considered especially in patients have a history of cardiac disease (e.g., arrhythmia) and atypical presentations of panic symptoms. Panic disorder is a psychiatric condition that is typically diagnosed after other medical conditions have been excluded. Because the diagnosis of sarcoidosis is difficult in some patients, caution is required. The palpitations and symptoms of heart failure associated with cardiac sarcoidosis can be misdiagnosed as psychiatric symptoms of panic disorder. The condition described in the current case study appears to constitute a physical disease, the diagnosis of which requires significant consideration and caution.

We report the first published case study of a suddenly occurring panic attack in a patient with no prior history of panic disorder during combined functional magnetic resonance imaging (fMRI, 1.5 Tesla) and electrocardiogram (ECG) recording. The single case was a 46-year-old woman who developed a panic attack near the planned end of the fMRI acquisition session, which therefore had to be aborted. Correlational analysis of heart rate fluctuations and fMRI data revealed a significant negative association in the left middle temporal gyrus. Additionally, regions-of-interest (ROI) analyses indicated significant positive associations in the left amygdala, and trends towards significance in the right amygdala and left insula.

The current study evaluated a novel latent structural model of anxiety sensitivity (AS) in relation to panic vulnerability among a sample of young adults (N=216). AS was measured using the 16-item Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), and panic vulnerability was indexed by panic attack responding to a single administration of a 4-minute, 10% CO(2) challenge. As predicted, vulnerability for panic attack responding to biological challenge was associated with dichotomous individual differences between taxonic AS classes and continuous within-taxon class individual differences in AS physical concerns. Findings supported the AS taxonic-dimensional hypothesis of AS latent structure and panic vulnerability. These findings are discussed in terms of their theoretical and clinical implications.

Co-morbidity of mood and anxiety disorders is common and often associated with greater illness severity. This study investigates clinical correlates and familiality of four anxiety disorders in a large sample of bipolar disorder (BP) and major depressive disorder (MDD) pedigrees. The sample comprised 566 BP families with 1416 affected subjects and 675 MDD families with 1726 affected subjects. Clinical characteristics and familiality of panic disorder, social phobia, specific phobia and obsessive-compulsive disorder (OCD) were examined in BP and MDD pedigrees with multivariate modeling using generalized estimating equations. Co-morbidity between mood and anxiety disorders was associated with several markers of clinical severity, including earlier age of onset, greater number of depressive episodes and higher prevalence of attempted suicide, when compared with mood disorder without co-morbid anxiety. Familial aggregation was found with co-morbid panic and OCD in both BP and MDD pedigrees. Specific phobia showed familial aggregation in both MDD and BP families, although the findings in BP were just short of statistical significance after adjusting for other anxiety co-morbidities. We found no evidence for familiality of social phobia. Our findings suggest that co-morbidity of MDD and BP with specific anxiety disorders (OCD, panic disorder and specific phobia) is at least partly due to familial factors, which may be of relevance to both phenotypic and genetic studies of co-morbidity.

Panic disorder and agoraphobia: an overview and commentary on DSM-5 changes.

PubMed

Asmundson, Gordon J G; Taylor, Steven; Smits, Jasper A J

2014-06-01

The recently published DSM-5 contains a number of changes pertinent to panic disorder and agoraphobia. These changes include separation of panic disorder and agoraphobia into separate diagnoses, the addition of criteria and guidelines for distinguishing agoraphobia from specific phobia, the addition of a 6-month duration requirement for agoraphobia, the addition of panic attacks as a specifier to any DSM-5 diagnosis, changes to descriptors of panic attack types, as well as various changes to the descriptive text. It is crucial that clinicians and researchers working with individuals presenting with panic attacks and panic-like symptoms understand these changes. The purpose of the current paper is to provide a summary of the main changes, to critique the changes in the context of available empirical evidence, and to highlight clinical implications and potential impact on mental health service utilization. Several of the changes have the potential to improve access to evidence-based treatment; yet, although certain changes appear justified in that they were based on converging evidence from different empirical sources, other changes appear questionable, at least based on the information presented in the DSM-5 text and related publications. Ongoing research of DSM-5 panic disorder and agoraphobia as well as application of the new diagnostic criteria in clinical contexts is needed to further inform the strengths and limitations of DSM-5 conceptualizations of panic disorder and agoraphobia. © 2014 Wiley Periodicals, Inc.

Panic disorder is an anxiety disorder that involves recurrent panic attacks, which emerge when a harmless stimulus is interpreted as "catastrophic". In an attempt to avoid the panic attack or prevent confrontation, the patient exhibits a dysfunctional attitude and behavior, such as evasion and safety-seeking behavior (SSB). Dysfunctional behavior leads to an increase in the recurrence of panic attacks and affects the patient's life in a negative way. According to the cognitive behavioral therapy model, SSB contributes to the continuation of unrealistic beliefs (e.g. physical experiences) regarding and prevents the patient from grasping new information that may potentially contradict the unrealistic cognitions. In this paper, we present a case with a primary diagnosis of panic disorder. Interestingly, this patient developed diabetes mellitus (DM) type 2 and psychogenic polydipsia (PPD) as a consequence of his SSB. PPD is a common occurrence in patients with psychiatric disorders, especially in schizophrenia. Up to now, no case of a panic disorder with either DM or PPD has been reported in the literature. While it is accepted that major depression poses a risk for DM type 2, panic disorder may also increase this risk. Treatment of the panic disorder with cognitive behavioral therapy (CBT) resulted in improvement of PPD and DM type 2. In conclusion, the role of SSB in medical disorders accompanied by psychiatric disorders should be kept in mind when treating these patients.

Individuals who experience one type of trauma often experience other types, yet few studies have examined the clustering of trauma. This study examines the clustering of traumatic events and associations of trauma with risk for single and co-occurring major depressive disorder (MDD) and panic attack for 20 years after first trauma. Lifetime histories of MDD, panic attack, and traumatic events were obtained from participants in an Australian twin sample. Latent class analysis was used to derive trauma classes based on each respondent's trauma history. Associations of the resulting classes and of parental alcohol problems and familial effects with risk for a first onset of single and co-occurring MDD and panic attack were examined from the year of first trauma to 20 years later. Traumatic events clustered into three distinct classes characterized by endorsement of little or no trauma, primarily nonassaultive, and primarily assaultive events. Individuals in the assaultive class were characterized by a younger age at first trauma, a greater number of traumatic events, and high rates of parental alcohol problems. Members of the assaultive trauma class had the strongest and most enduring risk for single and co-occurring lifetime MDD and panic attack. Assaultive trauma outweighed associations of familial effects and nonassaultive trauma with risk for 10 years following first trauma.

Dynamic single-photon emission computed axial tomography (CAT) with inhaled xenon-133 was used to measure regional cerebral blood flow in 10 drug-free patients with DSM-III-diagnosed panic disorder and in five normal control subjects. All subjects underwent regional cerebral blood flow studies while at rest or during normal saline infusion and during sodium lactate infusion. Six of the 10 patients and none of the control subjects experienced lactate-induced panic attacks. Lactate infusion markedly raised hemispheric blood flow levels in both control subjects and patients who did not panic.

This systematic review aimed to examine the results of studies that have investigated the induction of panic attacks and/or the anxiogenic effect of the caffeine challenge test in patients with panic disorder. The literature search was performed in PubMed, Biblioteca Virtual em Saúde and the ISI Web of Knowledge. The words used for the search were caffeine, caffeine challenge test, panic disorder, panic attacks and anxiety disorder. In total, we selected eight randomized, double-blind studies where caffeine was administered orally, and none of them controlled for confounding factors in the analysis. The percentage of loss during follow-up ranged between 14.3% and 73.1%. The eight studies all showed a positive association between caffeine and anxiogenic effects and/or panic disorder.

Until recently, the cerebellum was primarily considered to be a structure involved in motor behaviour. New anatomical and clinical evidence has shown that the cerebellum is also involved in higher cognitive functions and non-motor behavioural changes. Functional imaging in patients with anxiety disorders and in cholecystokinin tetrapeptide-induced panic-attacks shows activation changes in the cerebellum. Deep brain stimulation of the dorsolateral periaqueductal grey (dlPAG) and the ventromedial hypothalamus (VMH) in rats has been shown to induce escape behaviour, which mimics a panic attack in humans. We used this animal model to study the neuronal activation in the deep cerebellar nuclei (DCbN) using c-Fos immunohistochemistry. c-Fos expression in the DCbN decreased significantly after inducing escape behaviour by stimulation of the dlPAG and the VMH, indicating that the DCbN were deactivated. This study demonstrates that the DCbN are directly or indirectly involved in panic attacks. We suggest that the cerebellum plays a role in the selection of relevant information, and that deactivation of the cerebellar nuclei is required to allow inappropriate behaviour to occur, such as panic attacks.

When the threat comes from inside the body: a neuroscience based learning perspective of the etiology of panic disorder.

PubMed

Hamm, Alfons O; Richter, Jan; Pané-Farré, Christiane A

2014-01-01

Unexpected, recurrent panic attacks and anxious apprehension are two distinct emotional phenomena that constitute the core symptoms for diagnosing panic disorder. Taking a neuroscience perspective the current review paper presents both epidemiological and experimental psychophysiological evidence suggesting that panic attacks can be conceptualized as an unconditioned circa defense response pattern to intense internal threat stimuli, characterized by strong autonomic surge and escape behavior and abnormal plastic changes of the brain. Anxious apprehension develops after the experience of such severe panic attacks as conditioned responses to mild body symptoms. Theoretically these conditioned fear responses can be considered as post-encounter defense characterized by increased selective attention, increased threat appraisal and defensive freezing and startle potentiation evidencing altered brain circuits evoked by mild body symptoms. Agoraphobic avoidance starts very early during the defensive cascade and can be conceived as motivated behavior driven by the incentive to be in a safe context that is under control of the individual.

Management of anxiety in late life.

PubMed

Flint, A J

1998-01-01

Epidemiologic data are used as a framework to discuss the pharmacologic and cognitive-behavioral management of anxiety disorders in late life. Generalized anxiety disorder (GAD) and phobias account for most cases of anxiety in late life. The high level of comorbidity between GAD and major depression, and the observation that the anxiety usually arises secondarily to the depression, suggests that antidepressant medication should be the primary pharmacologic treatment for many older people with GAD. Most individuals with late-onset agoraphobia do not have a history of panic attacks and the illness often starts after a traumatic event. Exposure therapy is the treatment of choice for agoraphobia without panic. It is uncommon for obsessive-compulsive disorder (OCD) and panic disorder to start for the first time in old age, but these disorders can persist from younger years into late life. Case reports and uncontrolled case series suggest that elderly people with OCD or panic disorder can benefit from pharmacologic and cognitive-behavioral treatments that are known to be effective in younger patients. However, it is not known whether the rate of response among elderly patients is adversely affected by the chronicity of these disorders. The prevalence and incidence of post-traumatic stress disorder in late life are not known. Uncontrolled data support the use of selective serotonin reuptake inhibitors in war veterans with chronic symptoms of post-traumatic stress disorder; other treatments for this condition await evaluation in the elderly.

Some authors affirm that the anxiety of panic attacks is endogenous and of different quality that the common fear. But objective clinical data don't exist that confirm that observation. The authors study by means of a discriminant analysis the description of the anxiety made by subject with panic attacks and normal subjects with common fear. It meet a discriminant function that shows the existence of qualitative differences between both experiences. It seem to have achieved enough empirical support in order to sustain that the anxiety of panic attacks and the common fear are two qualitatively different experiences; presumably due to their several origin.

It has been argued that measurement of outcome in panic disorder should not be limited to monitoring the number of panic attacks, but should include all domains that affect patient quality of life. Data from a randomized prospective comparison of escitalopram, citalopram, and placebo in patients with DSM-IV panic disorder were analyzed with regard to measurements of impairment of quality of life. The subscales of the Panic and Agoraphobia Scale (P&A) (Panic Attacks, Agoraphobic Avoidance, Anticipatory Anxiety, Functional and Social Disability, and Worries about Health) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) were analyzed. Treatment with escitalopram was associated with significant improvement on all 5 subscales of the P&A. Citalopram was significantly different from placebo in 3 subscales. Escitalopram and citalopram were significantly better than placebo in improving quality of life (measured by the total score of the Q-LES-Q Scale). Escitalopram was superior to placebo on 12 of 16 items of the Q-LES-Q, while citalopram was superior on 7 items. The P&A scale was more robust than measurement of panic frequency in differentiating medication from placebo. Escitalopram treatment was associated with improvement on all assessed domains that impair quality of life in panic disorder. Measurement of clinical improvement should not be solely based on panic attack frequency, but should also include assessment of a broad range of domains that affect patient quality of life.

Panic disorder is characterized by sudden, repeated, and unexpected attacks of intense fear and overwhelming anxiety about when another attack may strike. Patients with panic disorder and healthy individuals with a history of panic attacks show a hypersensitivity to unpredictable threats, suggesting a possible link between panic and sustained anxiety. The purpose of this study was to determine the degree to which induced symptoms of panic relate to fear and anxiety, as well as activity in the neural systems that mediate and regulate these affective states. Psychological and physiological symptoms of panic were assessed during an 8-min 7.5% CO 2 challenge task. Psychological, physiological, and neural symptoms of fear and anxiety were measured during two sessions (one psychophysiology and one functional magnetic resonance imaging where subjects experienced several blocks of no threat (N), predictable shock (P), and unpredictable shock (U; NPU threat task). We used a principle component analysis to characterize panic susceptibility (PS), and found that PS significantly predicted dorsolateral prefrontal cortex (dlPFC) activity to the unpredictable cue during the NPU threat task. When examining the weighted beta coefficients from this analysis, we observed that self-reported fear/anxiety during the CO 2 challenge negatively loaded onto dlPFC activity during the NPU task. Consistent with this observation, dlPFC activity during the unpredictable cue was also negatively correlated with anxiety during the NPU sessions. Together, these results suggest that panic symptoms and anxiety are regulated by the same prefrontal cognitive control system.

Panic attack triggering myocardial ischemia documented by myocardial perfusion imaging study. A case report

Background Chest pain, a key element in the investigation of coronary artery disease is often regarded as a benign prognosis when present in panic attacks. However, panic disorder has been suggested as an independent risk factor for long-term prognosis of cardiovascular diseases and a trigger of acute myocardial infarction. Objective Faced with the extreme importance in differentiate from ischemic to non-ischemic chest pain, we report a case of panic attack induced by inhalation of 35% carbon dioxide triggering myocardial ischemia, documented by myocardial perfusion imaging study. Discussion Panic attack is undoubtedly a strong component of mental stress. Patients with coronary artery disease may present myocardial ischemia in mental stress response by two ways: an increase in coronary vasomotor tone or a sympathetic hyperactivity leading to a rise in myocardial oxygen consumption. Coronary artery spasm was presumed to be present in cases of cardiac ischemia linked to panic disorder. Possibly the carbon dioxide challenge test could trigger myocardial ischemia by the same mechanisms. Conclusion The use of mental stress has been suggested as an alternative method for myocardial ischemia investigation. Based on translational medicine objectives the use of CO2 challenge followed by Sestamibi SPECT could be a useful method to allow improved application of research-based knowledge to the medical field, specifically at the interface of PD and cardiovascular disease.

This study aims to examine whether specific anxiety disorder comorbidity alters the purported association between depression and specific cardiovascular diseases (CVDs). In 4,181 representative German participants of the general population, 12-month prevalence of psychiatric disorders was assessed through the Composite International Diagnostic Interview and CVDs by physician verified diagnosis. Adjusting for conventional risk factors logistic regression analyzed the association between CVDs (peripheral vascular disease (PVD), hypertension, cerebrovascular disease and heart disease) and combinations of comorbidity between depression and anxiety disorder types (panic disorder, specific phobia, social phobia and generalized anxiety). There were 770 cases of hypertension (18.4 %), 763 cases of cerebrovascular disease (18.2 %), 748 cases of PVD (17.9 %), and 1,087 cases of CVD (26.0 %). In adjusted analyses phobia comorbid with depression was associated with cerebrovascular disease (odds ratio (OR) 1.61; 95 % confidence interval (CI) 1.04-2.50) as was panic disorder (OR 2.89; 95 % CI 1.47-5.69). PVD was significantly associated with panic disorder (adjusted OR 2.97; 95 % CI 1.55-5.69). Panic disorder was associated with CVDs (adjusted OR 2.28; 95 % CI 1.09-4.77) as was phobia (adjusted OR 1.35; 95 % CI 1.04-1.78). Classification of anxiety and depression according to comorbidity groups showed discrete effects for panic disorder and specific phobia with CVDs, independent from covariates and depression.

2009-10-01

The current investigation explored the main and interactive effects of panic attacks in response to laboratory-induced bodily sensations and anxiety sensitivity in predicting acute nicotine withdrawal symptoms among daily smokers making a self-guided quit attempt. Participants were 99 daily smokers (58% women; M(age) = 28.4 years, SD = 11.7) who completed a battery of questionnaires, a voluntary hyperventilation challenge, and a measure of nicotine withdrawal symptoms 12 hr after making a self-guided quit attempt. Results indicated that the interaction of anxiety sensitivity and panic responsivity to the challenge predicted quit-day nicotine withdrawal symptom severity above and beyond the main effects (p < .05). The form of the interaction indicated that the relationship between postchallenge panic attack status and acute nicotine withdrawal was more robust among individuals who were low in anxiety sensitivity. Individuals who did not experience a panic attack posthyperventilation who were also low in anxiety sensitivity reported the lowest levels of nicotine withdrawal. Results suggest that anxiety sensitivity may be less relevant with regard to acute nicotine withdrawal severity among individuals with panic-related problems.

Panic attack and its correlation with acute coronary syndrome - more than just a diagnosis of exclusion.

PubMed

Soh, Keng Chuan; Lee, Cheng

2010-03-01

The panic attack is able to mimic the clinical presentation of an acute coronary syndrome (ACS), to the point of being clinically indistinguishable without appropriate investigations. However, the literature actually demonstrates that the 2 conditions are more related than just being differential diagnoses. Through a review of the literature involving epidemiological studies, randomised controlled trials, systematic reviews and meta-analyses found on a Medline search, the relation between panic disorder and ACS is explored in greater depth. Panic disorder, a psychiatric condition with recurrent panic attacks, has been found to be an independent risk factor for subsequent coronary events. This has prognostic bearing and higher mortality rates. Through activation of the sympathetic system by differing upstream mechanisms, the 2 conditions have similar presentations. Another psychiatric differential diagnosis would be that of akathisia, as an adverse effect to antidepressant medications. An overview on the investigations, diagnostic process, treatment modalities and prognoses of the two conditions is presented. Panic disorders remain under-diagnosed, but various interviews are shown to allow physicians without psychiatric training to accurately pick up the condition. Comprehensive multidisciplinary approaches are needed to help patients with both coronary heart disease and anxiety disorder.

Context The scarcity of cross-national reports and the changes in DSM-5 regarding panic disorder (PD) and panic attacks (PAs) call for new epidemiological data on PD and PAs and its subtypes in the general population. Objective To present representative data about the cross-national epidemiology of PD and PAs in accordance with DSM-5 definitions. Design and Setting Nationally representative cross-sectional surveys using the World Health Organization Composite International Diagnostic Interview version 3.0. Participants Respondents (n=142,949) from 25 high, middle and lower-middle income countries across the world aged 18 years or older. Main Outcome Measures PD and presence of single and recurrent PAs. Results Lifetime prevalence of PAs was 13.2% (s.e. 0.1%). Among persons that ever had a PA, the majority had recurrent PAs (66.5%; s.e. 0.5%), while only 12.8% fulfilled DSM-5 criteria for PD. Recurrent PAs were associated with a subsequent onset of a variety of mental disorders (OR 2.0; 95% CI 1.8–2.2) and their course (OR 1.3; 95% CI 1.2–2.4) whereas single PAs were not (OR 1.1; 95% CI 0.9–1.3 and OR 0.7; 95% CI 0.6–0.8). Cross-national lifetime prevalence estimates were 1.7% (s.e. 0.0%) for PD with a median age of onset of 32 (IQR 20–47). Some 80.4% of persons with lifetime PD had a lifetime comorbid mental disorder. Conclusions We extended previous epidemiological data to a cross-national context. The presence of recurrent PAs in particular is associated with subsequent onset and course of mental disorders beyond agoraphobia and PD, and might serve as a generic risk marker for psychopathology.

In this study we examined how personality disposition may affect the response to cholecystokinin tetrapeptide (CCK-4; 50 microg) challenge in healthy volunteers (n=105). Personality traits were assessed with the Swedish universities Scales of Personality (SSP). Statistical methods employed were correlation analysis and logistic regression. The results showed that the occurrence of CCK-4-induced panic attacks was best predicted by baseline diastolic blood pressure, preceding anxiety and SSP-defined traits of lack of assertiveness, detachment, embitterment and verbal aggression. Significant interactions were noted between the above mentioned variables, modifying their individual effects. For different subsets of CCK-4-induced symptoms, the traits of physical aggression, irritability, somatic anxiety and stress susceptibility also appeared related to panic manifestations. These findings suggest that some personality traits and their interactions may influence vulnerability to CCK-4-induced panic attacks in healthy volunteers. Copyright 2010 Elsevier Ireland Ltd.

1995-04-01

The aim of the current study was to determine the degree to which patients with panic disorder develop tolerance to subjective and physiological effects of benzodiazepine after chronic treatment with alprazolam. Response to acute administration of diazepam was assessed in 19 panic disorder patients receiving chronic treatment with alprazolam and 23 untreated panic disorder patients. At baseline in the laboratory, the two groups did not differ in peak saccadic eye movement velocity, saccade latency, short-term memory, plasma cortisol and growth hormone concentrations, heart rate, and self-rated levels of sedation and anxiety. Compared with untreated patients, alprazolam-treated patients displayed significantly less diazepam-induced change in peak saccadic velocity, saccade latency, growth hormone secretion, memory, and self-rated levels of sedation. There was no difference between groups in diazepam effects on plasma cortisol concentrations or self-rated anxiety. Within alprazolam-treated patients, diazepam-induced slowing of peak saccade velocity was significantly inversely correlated with illness severity, as measured by reported panic attacks per week and severity of phobic avoidance, but not with alprazolam dose, blood level, or duration of treatment. Because the alprazolam-treated group reported more panic attacks per week than the untreated panic patients, treated patients were divided into those who were asymptomatic versus those with continuing panic attacks. The subgroup of nine alprazolam-treated subjects who were asymptomatic also showed significantly less diazepam effects than the group of untreated panic disorder patients, suggesting that overall group differences were at least partially attributable to the development of tolerance to selected benzodiazepine effects with chronic alprazolam treatment.

To develop and validate a risk prediction algorithm for the recurrence of panic disorder. Three-year longitudinal data were taken from the National Epidemiologic Survey on Alcohol and Related Conditions (2001/2002-2004/2005). One thousand six hundred and eighty one participants with a lifetime panic disorder and who had not had panic attacks for at least 2 months at baseline were included. The development cohort included 949 participants; 732 from different census regions were in the validation cohort. Recurrence of panic disorder over the follow-up period was assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule, based on the DSM-IV criteria. Logistic regression was used for deriving the algorithm. Discrimination and calibration were assessed in the development and the validation cohorts. The developed algorithm consisted of 11 predictors: age, sex, panic disorder in the past 12 months, nicotine dependence, rapid heartbeat/tachycardia, taking medication for panic attacks, feelings of choking and persistent worry about having another panic attack, two personality traits, and childhood trauma. The algorithm had good discriminative power (C statistic = 0.7863, 95% CI: 0.7487, 0.8240). The C statistic was 0.7283 (95% CI: 0.6889, 0.7764) in the external validation data set. The developed risk algorithm for predicting the recurrence of panic disorder has good discrimination and excellent calibration. Data related to the predictors can be easily attainable in routine clinical practice. It can be used by clinicians to calculate the probability of recurrence of panic disorder in the next 3 years for individual patients, communicate with patients regarding personal risks, and thus improve personalized treatment approaches. © 2015 Wiley Periodicals, Inc.

Changes in central sodium and not osmolarity or lactate induce panic-like responses in a model of panic disorder.

2010-05-01

Panic disorder is a severe anxiety disorder characterized by recurrent panic attacks that can be consistently provoked with intravenous (i.v.) infusions of hypertonic (0.5 M) sodium lactate (NaLac), yet the mechanism/CNS site by which this stimulus triggers panic attacks is unclear. Chronic inhibition of GABAergic synthesis in the dorsomedial hypothalamus/perifornical region (DMH/PeF) of rats induces a vulnerability to panic-like responses after i.v. infusion of 0.5 M NaLac, providing an animal model of panic disorder. Using this panic model, we previously showed that inhibiting the anterior third ventricle region (A3Vr; containing the organum vasculosum lamina terminalis, the median preoptic nucleus, and anteroventral periventricular nucleus) attenuates cardiorespiratory and behavioral responses elicited by i.v. infusions of NaLac. In this study, we show that i.v. infusions of 0.5 M NaLac or sodium chloride, but not iso-osmolar D-mannitol, increased 'anxiety' (decreased social interaction) behaviors, heart rate, and blood pressure responses. Using whole-cell patch-clamp preparations, we also show that bath applications of NaLac (positive control), but not lactic acid (lactate stimulus) or D-mannitol (osmolar stimulus), increases the firing rates of neurons in the A3Vr, which are retrogradely labeled from the DMH/PeF and which are most likely glutamatergic based on a separate study using retrograde tracing from the DMH/PeF in combination with in situ hybridization for vesicular glutamate transporter 2. These data show that hypertonic sodium, but not hyper-osmolarity or changes in lactate, is the key stimulus that provokes panic attacks in panic disorder, and is consistent with human studies.

Panic and comorbid depression and their associations with stress reactivity, interoceptive awareness and interoceptive accuracy of various bioparameters.

PubMed

Limmer, Jan; Kornhuber, Johannes; Martin, Alexandra

2015-10-01

While current theories on perception of interoceptive signals suggest impaired interoceptive processing in psychiatric disorders such as panic disorder or depression, heart-rate (HR) interoceptive accuracy (IAc) of panic patients under resting conditions is superior to that of healthy controls. Thus, in this study, we chose to assess further physiological parameters and comorbid depression in order to get information on how these potentially conflicting findings are linked together. We used a quasi-experimental laboratory design which included multi-parametric physiological data collection of 40 panic subjects and 53 matched no-panic controls, as well as experimental induction of stress and relaxation over a time-course. Stress reactivity, interoceptive awareness (IAw; from the Body Perception Questionnaire (BPQ)) and IAc (as correlation between self-estimation and physiological data) were major outcome variables. Self-estimation of bioparametrical change was measured via numeric rating scales. Panic subjects had stronger HR-reaction and more accurate HR-interoception. Concurrently, though, their IAc of skin conductance level, pulse amplitude and breathing amplitude was significantly lower than that of the control group. Interestingly, comorbid depression was found to be associated with increased IAw but attenuated IAc. Demand characteristics and a categorical approach to panic confine the results. The potentially conflicting findings coalesce, as panic was associated with an increase of the ability to perceive the fear-related parameter and a simultaneous decrease of the ability to perceive other parameters. The superordinate integration of afferent signals might be impaired. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

A review of cognitive behavioral therapy for panic disorder in patients with chronic obstructive pulmonary disease: the rationale for interoceptive exposure.

Panic disorder commonly co-occurs in patients with chronic obstructive pulmonary disease (COPD), and translational interventions are needed to address the fear of physiological arousal in this population. This paper examines the utility of interoceptive exposures (IE), a key component of cognitive behavioral therapy (CBT) for panic disorder, in patients with comorbid panic and COPD. Our translational review of the literature suggests that IE is supported by both cognitive- and learning-theory perspectives of panic, and that the breathing exercises associated with IE are safe and highly compatible with existing pulmonary rehabilitation exercises for COPD. Unfortunately, few research studies have examined the use of CBT to treat anxiety in COPD patients, and none have included IE. Given the strong theoretical and empirical support for the use of IE, we suggest that mental health providers should consider incorporating IE into CBT interventions for patients with comorbid panic and COPD.

We evaluated two protocols for treating adults with comorbid asthma and panic disorder. The protocols included elements of Barlow’s “panic control therapy” and several asthma education programs, as well as modules designed to teach participants how to differentiate asthma and panic symptoms, and how to apply specific home management strategies for each. Fifty percent of subjects dropped out of a 14-session protocol by the eighth session; however, 83% of patients were retained in an eight-session protocol. Clinical results were mostly equivalent: significant decreases of >50% in panic symptoms, clinically significant decreases in asthma symptoms, improvement in asthma quality of life, and maintenance of clinical stability in asthma. Albuterol use decreased significantly in the 14-session protocol and at a borderline level in the 8-session protocol, while pulmonary function was maintained. A controlled evaluation of this procedure is warranted. PMID:17693054

Understanding the temporal sequencing of alcohol use disorders (AUDs) and comorbid mood and anxiety disorders may help to disentangle the etiological underpinnings of comorbidity. Methodological limitations of previous studies, however, may have led to inconsistent or inconclusive findings. To describe the temporal sequencing of the onset of AUDs relative to the onset of specific comorbid mood and anxiety disorders using a large, nationally representative survey. AUD onset tended to follow the onset of 2 of the 9 mood and anxiety disorders (specific and social phobia). The onset of alcohol abuse tended to precede the onset of 5 of the 9 mood and anxiety disorders (GAD, panic, panic with agoraphobia, major depression, and dysthymia), whereas the onset of alcohol dependence tended to precede the onset of only 2 of the 9 mood and anxiety disorders (GAD and panic). Lag times between primary and subsequent disorders generally ranged from 7 to 16 years. Comorbid individuals whose alcohol dependence came after panic with agoraphobia, hypomania, and GAD had increased risk of persistent alcohol dependence. Alcohol abuse, but not dependence, precedes many mood and anxiety disorders. If the primary disorder does in fact play a causative or contributing role in the development of the subsequent disorder, this role can best be described as "temporally distal." However, in assessing the risk for persistent alcohol dependence, clinicians should not only consider the type of comorbid mood/anxiety disorder, but also the temporal ordering of these disorders.

The Experience of Panic Symptoms across Racial Groups in a Student Sample

While there is general agreement that, across cultures, panic disorder appears to be characterized by sudden onset of bodily sensations, such as dizziness and heart palpitations, followed by catastrophic misinterpretations of these symptoms, there remains a need for research investigating ethnic/cultural differences in the experience of panic attacks. In addition to investigating ethnic differences in the experience of panic, it is important to assess whether increased endorsement of panic symptoms translates into increased dysfunction. The present study investigated differences in the experience of panic attacks and examined the relation between symptom endorsement and overall distress and impairment in a large multiracial/ethnic student population. Preliminary analyses indicated that although overall endorsement of panic symptoms was similar across groups, differences did emerge on specific symptoms. Participants identifying as Asian tended to endorse symptoms such as dizziness, unsteadiness, choking, and feeling terrified more frequently than those identifying as Caucasian, and individuals identifying as African American reported feeling less nervous than those identifying as Caucasian. Participants of Hispanic/Latino(a) descent showed no differences from any other group on symptom endorsement. Panic symptom severity was not found to differ across racial/ethnic groups; however, the correlation between panic symptoms and panic severity was stronger for Asian and Caucasian participants than for African Americans. These results suggest that symptoms of panic may be experienced differently across racial/ethnic groups, and highlight the need for clinicians and researchers to assess panic symptoms within the context of culture.

Lesional Temporal Lobe Epilepsy: Beware the Deceitful "Panic Attack".

2018-03-01

Ganglioglioma is a rare, benign, intraaxial glioneuronal tumor but a relatively common cause of pharmacoresistant temporal lobe epilepsy (TLE). Given its often nonspecific neuropsychiatric manifestations and frequently negative electroencephalographic workup, TLE can be easily misdiagnosed as a psychiatric disorder, particularly panic attacks. We present a case of a 17-year-old boy who was found to have lesional TLE secondary to a left temporal ganglioglioma, 5 years after having been misdiagnosed with panic disorder and having undergone ineffective and unnecessary psychotherapy. He was successfully cured by surgery. Although a few similar cases of TLE masquerading as a panic disorder have been previously reported in the literature, this is the youngest and only pediatric patient described to date. This report underscores the challenges in making an accurate clinical diagnosis of TLE and the importance of timely brain imaging whenever an atypical or medically refractory panic disorder is encountered.

Exogenous factors in panic disorder: clinical and research implications.

PubMed

Roy-Byrne, P P; Uhde, T W

1988-02-01

Because panic disorder has an underlying biologic and probably genetic basis, the role of factors outside the organism in initiating and sustaining panic is often overlooked. The authors review certain exogenous factors that seem capable of triggering attacks and/or increasing their frequency and intensity: self-administered pharmacologic agents (caffeine, alcohol, nicotine, over-the-counter cold preparations, cannabis, cocaine); habits (sleep deprivation, diet, exercise, relaxation, hyperventilation); and aspects of the environment (fluorescent lighting, life stressors). There may be a specificity to the action of some of these factors, because certain factors previously thought to trigger panic attacks (e.g., pain, hypoglycemia) have been proved not to have this effect. Although the clinical significance of many of the exogenous factors discussed still awaits empirical confirmation, attention to such factors during the initial evaluation of a patient with panic disorder may be helpful in formulating a successful treatment plan.

Panic and phobic anxiety: associations among neuroticism, physiological hyperarousal, anxiety sensitivity, and three phobias.

Longley, Susan L; Watson, David; Noyes, Russell; Yoder, Kevin

2006-01-01

A dimensional and psychometrically informed taxonomy of anxiety is emerging, but the specific and nonspecific dimensions of panic and phobic anxiety require greater clarification. In this study, confirmatory factor analyses of data from a sample of 438 college students were used to validate a model of panic and phobic anxiety with six content factors; multiple scales from self-report measures were indicators of each model component. The model included a nonspecific component of (1) neuroticism and two specific components of panic attack, (2) physiological hyperarousal, and (3) anxiety sensitivity. The model also included three phobia components of (4) classically defined agoraphobia, (5) social phobia, and (6) blood-injection phobia. In these data, agoraphobia correlated more strongly with both the social phobia and blood phobia components than with either the physiological hyperarousal or the anxiety sensitivity components. These findings suggest that the association between panic attacks and agoraphobia warrants greater attention.

How study of respiratory physiology aided our understanding of abnormal brain function in panic disorder.

PubMed

Sinha, S; Papp, L A; Gorman, J M

2000-12-01

There is a substantial body of literature demonstrating that stimulation of respiration (hyperventilation) is a common event in panic disorder patients during panic attack episodes. Further, a number of abnormalities in respiration, such as enhanced CO2 sensitivity, have been detected in panic patients. This led some to posit that there is a fundamental abnormality in the physiological mechanisms that control breathing in panic disorder and that this abnormality is central to illness etiology. More recently, however, evidence has accumulated suggesting that respiratory physiology is normal in panic patients and that their tendency to hyperventilate and to react with panic to respiratory stimulants like CO2 represents the triggering of a hypersensitive fear network. The fear network anatomy is taken from preclinical studies that have identified the brain pathways that subserve the acquisition and maintenance of conditioned fear. Included are the amygdala and its brain stem projections, the hippocampus, and the medial prefrontal cortex. Although attempts to image this system in patients during panic attacks have been difficult, the theory that the fear network is operative and hyperactive in panic patients explains why both medication and psychosocial therapies are clearly effective. Studies of respiration in panic disorder are an excellent example of the way in which peripheral markers have guided researchers in developing a more complete picture of the neural events that occur in psychopathological states.

A 36-year-old man with comorbid panic disorder with agoraphobia, major depression, and histrionic personality disorder since age 21 was resistant to combined drug and psychotherapy treatment. His conditions had progressively worsened with time, causing him to withdraw socially and to simultaneously require continuous physical restraint, which further worsened his functioning. He spent almost 3 consecutive years in restraint, until he consented to receive bilateral ECT treatment. He improved after 13 sessions in all areas (social and role functioning, and panic, depressive, and histrionic symptoms) and is well 3 months later with a lithium-atypical antipsychotic combination.

Increased brain serotonin turnover in panic disorder patients in the absence of a panic attack: reduction by a selective serotonin reuptake inhibitor.

Since the brain neurotransmitter changes characterising panic disorder remain uncertain, we quantified brain noradrenaline and serotonin turnover in patients with panic disorder, in the absence of a panic attack. Thirty-four untreated patients with panic disorder and 24 matched healthy volunteers were studied. A novel method utilising internal jugular venous sampling, with thermodilution measurement of jugular blood flow, was used to directly quantify brain monoamine turnover, by measuring the overflow of noradrenaline and serotonin metabolites from the brain. Radiographic depiction of brain venous sinuses allowed differential venous sampling from cortical and subcortical regions. The relation of brain serotonin turnover to serotonin transporter genotype and panic disorder severity were evaluated, and the influence of an SSRI drug, citalopram, on serotonin turnover investigated. Brain noradrenaline turnover in panic disorder patients was similar to that in healthy subjects. In contrast, brain serotonin turnover, estimated from jugular venous overflow of the metabolite, 5-hydroxyindole acetic acid, was increased approximately 4-fold in subcortical brain regions and in the cerebral cortex (P < 0.01). Serotonin turnover was highest in patients with the most severe disease, was unrelated to serotonin transporter genotype, and was reduced by citalopram (P < 0.01). Normal brain noradrenaline turnover in panic disorder patients argues against primary importance of the locus coeruleus in this condition. The marked increase in serotonin turnover, in the absence of a panic attack, possibly represents an important underlying neurotransmitter substrate for the disorder, although this point remains uncertain. Support for this interpretation comes from the direct relationship which existed between serotonin turnover and illness severity, and the finding that SSRI administration reduced serotonin turnover. Serotonin transporter genotyping suggested that increased whole brain serotonin turnover most likely derived not from impaired serotonin reuptake, but from increased firing in serotonergic midbrain raphe neurons projecting to both subcortical brain regions and the cerebral cortex.

To determine the prevalence and clinical characteristics of comorbid obsessive compulsive disorders and syndromes (OCD/OCS), compared with pure OCD/OCS among adults in the community. Data were drawn from the Zurich Study, a longitudinal cohort study of 591 adults in the canton of Zurich. Comorbid OCD/OCS was compared with pure OCD/OCS groups in terms of distress, impairment, family history, suicide behavior and treatment using multivariable logistic regression analyses. OCD was significantly comorbid with bipolar I/II and minor bipolar disorders, anxiety states (GAD, repeated panic attacks) and social phobia, whereas there was no clear association between OCD and major depressive disorder or phobias other than social phobia. Results suggest that comorbid OCD/OCS is common among adults in the community, with the majority of those with OCD/OCS having at least one comorbid mood or anxiety disorder with a prevalence of 7.4% compared to 4.8% of remaining OCD/OCS. Comorbidity of OCD/OCS and anxiety states was more common among women (85.6 %) and comorbidity with bipolar spectrum was more common among men (69.6%). Comorbid OCD/OCS was associated with significantly higher levels of treatment seeking, impairment,distress and suicidality compared with pure OCD/OCS. Comorbidity with bipolar disorders significantly increased the risk for alcohol abuse/dependence. Comorbidity of OCD/OCS with bipolar disorder and bipolar spectrum disorders is common and very probably explains the association between OCD and depression found in other studies. The early recognition of bipolar/cyclothymic OCD/OCS may help to prevent the abuse of/dependence on alcohol.

Ataque de nervios ("attack of nerves") is an illness category used frequently by Hispanic individuals to describe one or more particular symptom complexes. A review of the literature on ataque suggested some overlap with panic disorder. This study investigated the overlap with panic disorder as well as other DSM-III-R axis I disorders. Hispanic subjects seeking treatment at an anxiety disorders clinic (N = 156) were assessed with a specially designed questionnaire for self-report of ataque de nervios and panic symptoms and with structured or semistructured psychiatric interviews for axis I disorders. Seventy percent of the subjects reported at least one ataque de nervios; 80% of these were female, whereas 57% of the group without these attacks were female. There were no differences in DSM-III-R diagnoses between the groups with and without ataque de nervios. Ataque was frequently associated with one or more anxiety and affective disorders, including panic disorder, generalized anxiety disorder, recurrent major depression, and anxiety not otherwise specified. Of the 45 subjects with both ataque de nervios and primary panic disorder, 80% appeared to have labeled panic disorder as ataque. Ataque de nervios was associated with panic symptoms even in subjects without panic disorder, but the self-reporting of ataque conveyed additional clinical information about the subjects with panic disorder. Ataque de nervios was similar in frequency and symptoms among subjects of Dominican and Puerto Rican origin. Ataque de nervios overlaps with panic disorder but is a more inclusive construct. Further study of its interrelation with axis I disorders is needed.

A randomized clinical trial of cognitive behavioral therapy and interpersonal psychotherapy for panic disorder with agoraphobia.

Vos, S P F; Huibers, M J H; Diels, L; Arntz, A

2012-12-01

Interpersonal psychotherapy (IPT) seems to be as effective as cognitive behavioral therapy (CBT) in the treatment of major depression. Because the onset of panic attacks is often related to increased interpersonal life stress, IPT has the potential to also treat panic disorder. To date, a preliminary open trial yielded promising results but there have been no randomized controlled trials directly comparing CBT and IPT for panic disorder. This study aimed to directly compare the effects of CBT versus IPT for the treatment of panic disorder with agoraphobia. Ninety-one adult patients with a primary diagnosis of DSM-III or DSM-IV panic disorder with agoraphobia were randomized. Primary outcomes were panic attack frequency and an idiosyncratic behavioral test. Secondary outcomes were panic and agoraphobia severity, panic-related cognitions, interpersonal functioning and general psychopathology. Measures were taken at 0, 3 and 4 months (baseline, end of treatment and follow-up). Intention-to-treat (ITT) analyses on the primary outcomes indicated superior effects for CBT in treating panic disorder with agoraphobia. Per-protocol analyses emphasized the differences between treatments and yielded larger effect sizes. Reductions in the secondary outcomes were equal for both treatments, except for agoraphobic complaints and behavior and the credibility ratings of negative interpretations of bodily sensations, all of which decreased more in CBT. CBT is the preferred treatment for panic disorder with agoraphobia compared to IPT. Mechanisms of change should be investigated further, along with long-term outcomes.

Abstract Auricular chromotherapy has shown promising results in the treatment of psychologic trauma and anxiety disorders, such as phobias and panic attacks. With its relatively easy and quick technical application, this procedure could be an indispensable tool for physicians. However, its mechanism of action is not yet understood completely. Objective: To treat patients suffering from trauma, phobia, and panic attack with auricular chromotherapy. Materials and Methods: The protocol was applied in 160 patients (135 who experienced traumas; 15 patients with specific phobias and 10 patients with panic disorder). They are 134 women, 26 men, ages 20–60. Results: The treatment showed 93% of positive response. Conclusion: This procedure shows the possibility of drawing a path from the external ear to traumatic memories, anxiety disorders and phobias.

Panic disorder (PD) is often correlated with high neuroticism and low extraversion. This study aims to ascertain whether PD patients differ from healthy controls in regard to personality traits and determine if these traits are correlated with comorbid disorders, anxiety, and depression symptoms. Personality traits of 69 PD patients and 42 controls were compared using the Maudsley Personality Inventory. In PD patients, comorbidities, anxiety, and depression symptoms were also evaluated. PD patients showed higher neuroticism and lower extraversion compared with healthy controls. Patients without comorbidities presented similar results to controls, whereas those with comorbidities presented higher neuroticism and lower extraversion scores. PD per se may be unrelated to deviant personality traits, although comorbidities with major depressive disorder and agoraphobia are probably associated with high neuroticism and low extraversion. These traits show a strong correlation with the accumulation and severity of these disorders.

Catastrophic misinterpretations as a predictor of symptom change during treatment for panic disorder.

PubMed

Teachman, Bethany A; Marker, Craig D; Clerkin, Elise M

2010-12-01

Cognitive models of panic disorder suggest that change in catastrophic misinterpretations of bodily sensations will predict symptom reduction. To examine change processes, we used a repeated measures design to evaluate whether the trajectory of change in misinterpretations over the course of 12-week cognitive behavior therapy is related to the trajectory of change in a variety of panic-relevant outcomes. Participants had a primary diagnosis of panic disorder (N = 43; 70% female; mean age = 40.14 years). Race or ethnicity was reported as 91% Caucasian, 5% African American, 2.3% biracial, and 2.3% "other." Change in catastrophic misinterpretations (assessed with the Brief Body Sensations Interpretation Questionnaire; Clark et al., 1997) was used to predict a variety of treatment outcomes, including overall panic symptom severity (assessed with the Panic Disorder Severity Scale [PDSS]; Shear et al., 1997), panic attack frequency (assessed with the relevant PDSS item), panic-related distress/apprehension (assessed by a latent factor, including peak anxiety in response to a panic-relevant stressor-a straw breathing task), and avoidance (assessed by a latent factor, which included the Fear Questionnaire-Agoraphobic Avoidance subscale; Marks & Mathews, 1979). Bivariate latent difference score modeling indicated that, as expected, change in catastrophic misinterpretations predicted subsequent reductions in overall symptom severity, panic attack frequency, distress/apprehension, and avoidance behavior. However, change in the various symptom domains was not typically a significant predictor of later interpretation change (except for the distress/apprehension factor). These results provide considerable support for the cognitive model of panic and speak to the temporal sequence of change processes during therapy. (c) 2010 APA, all rights reserved.

Few naturalistic, longitudinal studies of panic disorder with and without agoraphobia (PD/PDA) exist, limiting our knowledge of the temporal rates of incidence, relapse, and chronicity, or the factors that predict category transition. Data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) wave 1 (n=43,093) and wave 2 (n=34,653) were utilized to determine transitional rates, and predictors of category transitions, over a 3-year period. Analyses revealed very high 3-year remission rates for PD and PDA (75% and 67%, respectively), although relapse also was relatively frequent (PD=12%; PDA=21%). Logistic regression revealed previous history of panic attacks, generalized anxiety disorder/major depression (GAD/MDD), nicotine dependence, female sex, younger age, and major financial crises to be reliable predictors of incidence and relapse. The direction and magnitude of association of many predictor variables were similar for PD and PDA, with notable exceptions for social anxiety and romantic relationship factors. Clinicians should be aware of the relapsing-remitting nature of PD and PDA and, thus, take caution to not reduce or eliminate effective treatments prematurely. Similarly, the current study suggests clinicians pay particular attention to concurrent factors relevant to relapse in PD/PDA that may also be clinically addressed (e.g., co-morbid MDD/GAD and nicotine dependence).

Childhood Traumatic Experiences, Dissociative Symptoms, and Dissociative Disorder Comorbidity Among Patients With Panic Disorder: A Preliminary Study.

2015-01-01

This study assessed childhood trauma history, dissociative symptoms, and dissociative disorder comorbidity in patients with panic disorder (PD). A total of 92 psychotropic drug-naive patients with PD, recruited from outpatient clinics in the psychiatry department of a Turkish hospital, were involved in the study. Participants were assessed using the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), Dissociation Questionnaire, Panic and Agoraphobia Scale, Panic Disorder Severity Scale, and Childhood Trauma Questionnaire. Of the patients with PD, 18 (19%) had a comorbid dissociative disorder diagnosis on screening with the SCID-D. The most prevalent disorders were dissociative disorder not otherwise specified, dissociative amnesia, and depersonalization disorders. Patients with a high degree of dissociation symptoms and dissociative disorder comorbidity had more severe PD than those without (p < .05). All of the childhood trauma subscales used were correlated with the severity of symptoms of dissociation and PD. Among all of the subscales, the strongest relationship was with childhood emotional abuse. Logistic regression analysis showed that emotional abuse and severity of PD were independently associated with dissociative disorder. In our study, a significant proportion of the patients with PD had concurrent diagnoses of dissociative disorder. We conclude that the predominance of PD symptoms at admission should not lead the clinician to overlook the underlying dissociative process and associated traumatic experiences among these patients.

Besides several risk factors for suicide, there is a recent increase in clinical and epidemiological studies pointing to a potential relationship between sleep loss or sleep disturbances and suicidality. This work, based on a systematic literature research, gives an overview on the findings of relationships between suicidality (i. e., suicidal thoughts, suicide attempts, suicides) and sleep disturbances, especially insomnia, nightmares, but also hypersomnia and nocturnal panic attacks. There is evidence that sleep disturbances in suicidal insomniacs with comorbid psychiatric disorder are independently predictive for suicidality, too. Shared aspects of pathogenesis of the two entities and therapeutic options are also discussed. Recognition of sleep disturbances is essential for suicide prevention in clinical practice. © Georg Thieme Verlag KG Stuttgart · New York.

Panic anxiety, under the weather?

The relationship between weather conditions and psychiatric disorders has been a continuous subject of speculation due to contradictory findings. This study attempts to further clarify this relationship by focussing on specific conditions such as panic attacks and non-panic anxiety in relation to specific meteorological variables. All psychiatric emergencies attended at a general hospital in Barcelona (Spain) during 2002 with anxiety as main complaint were classified as panic or non-panic anxiety according to strict independent and retrospective criteria. Both groups were assessed and compared with meteorological data (wind speed and direction, daily rainfall, temperature, humidity and solar radiation). Seasons and weekend days were also included as independent variables. Non-parametric statistics were used throughout since most variables do not follow a normal distribution. Logistic regression models were applied to predict days with and without the clinical condition. Episodes of panic were three times more common with the poniente wind (hot wind), twice less often with rainfall, and one and a half times more common in autumn than in other seasons. These three trends (hot wind, rainfall and autumn) were accumulative for panic episodes in a logistic regression formula. Significant reduction of episodes on weekends was found only for non-panic episodes. Panic attacks, unlike other anxiety episodes, in a psychiatric emergency department in Barcelona seem to show significant meteorotropism. Assessing specific disorders instead of overall emergencies or other variables of a more general quality could shed new light on the relationship between weather conditions and behaviour.

The concept of Panic Disorders has itself been developed on the strength of therapeutic effects of drug treatments and it is therefore not surprising that psychotropic medications are currently the main therapeutic tool for this condition. Their use may be indicated in two differing circumstances, as treatment for Panic Attack itself or as a long-term treatment for what is properly called Panic Disorder. The latter scenario is that which has been most actively studied and represents the more original side of the question. Treatment of acute Panic Attack involves administration of sedative anxiolytics, principally benzodiazepines (BZD). Long-term treatment aiming to prevent repeated attacks is the core strategy for treatment for Panic Disorder. For the past fifteen years, a large number of research projects have shown the elective anti-panic efficacy of a number of drugs, principally antidepressants and anxiolytics. The response profile to anti-depressant treatment is characterized by a lag time which is sometimes longer than that observed when they are used solely as antidepressants; frequently they are also less well tolerated which necessitates a very gradual step-up in dosage. The "classic" MAOI (non-selective and irreversible) have a proven anti-panic effect. Selective serotonin reuptake inhibitor (SSRI) anti-depressants are currently drugs of choice in the treatment of Panic Disorder. Although the anti-panic effect appears to be common to all the various SSRI drugs available, and directly attributable to their mechanism of action, not all of them however have undergone controlled studies. In France, paroxetine is the first anti-depressant in this group to obtain a marketing authorization for this particular indication. The advantages of the SSRI drugs are principally related to their limited adverse effects and lack of toxicity, thereby making them particularly straightforward to use. Benzodiazepines (BZD) are the second group of psychotropic medications which have been shown to be effective in the treatment of Panic Disorder. The major disadvantage of the BZD for this indication is chiefly related to the major risk of promoting a dependency state with the corresponding appearance of a withdrawal syndrome when treatment is stopped. This risk constitutes a major stumbling block to the use of BZD as a first-line treatment for Panic Disorder. Various other drugs have been evaluated in the treatment of Panic Disorder with varying success. The current anti-panic pharmacopoeia therefore appears to be relatively well stocked. In this context, antidepressants-especially the SSRI drugs-are the first-line treatment of choice for Panic Disorders. In all cases, it appears useful to integrate pharmacological treatment within an overall management plan for the patient with Panic Disorder, especially if it is hoped to maintain therapeutic benefit long-term.

Cognitive Behavioral Treatment of Panic Disorder and Agoraphobia in a Multiethnic Urban Outpatient Clinic: Initial Presentation and Treatment Outcome

Few studies examine the effectiveness of panic control treatment across diverse ethnic groups. In this paper we present data on 40 patients (African American, n = 24; Caucasian, n = 16) with panic disorder and comorbid agoraphobia who presented at an anxiety disorder clinic in an inner-city area. On initial assessment both groups were similar on…

Panic disorder phenomenology in urban self-identified Caucasian-Non-Hispanics and Caucasian-Hispanics.

The epidemiology of panic disorder is well known, but data about some phenomenological aspects are sparse. The symptom criteria for panic disorder were developed largely from rational expert consensus methods and not from empirical research. This fact calls attention to the construct validity of the panic disorder diagnosis, which may affect accuracy of epidemiological findings. Seventy self-identified Non-Hispanic-Caucasian (Anglo) and Hispanic-Caucasian (Hispanic) people who were diagnosed with DSM-III-R panic disorder with or without agoraphobia were invited to complete a Panic Phenomenological Questionnaire (PPQ), which was constructed for this study from the Hamilton Anxiety Scale Items and The DSM-III-R panic symptoms. Fifty (71%) subjects agreed to participate, and there was no response bias detected. Seven symptoms on the PPQ that are not in the DSM-IV diagnostic criteria were reported to occur with a high prevalence in this study. Furthermore, many symptoms that occurred with a high frequency and were reported to be experienced as severe are also not included in current nosology. A few of the DSM-IV criterion symptoms occurred with low prevalence, frequency, and severity. Cognitive symptoms were reported to occur with higher frequency and severity during attacks than autonomic or other symptoms. There were modest differences between ethnic groups with regard to panic attack phenomena. Further research using multiple empirical methods aimed at improving the content validity of the panic disorder diagnosis is warranted. This includes utilizing consistent methods to collect data that will allow for rational decisions about how to construct valid panic disorder criteria across cultures.

This study aimed to investigate associations of job stressors with panic attack (PA) and panic disorder (PD) among Japanese workers. A cross-sectional online questionnaire survey was conducted of 2060 workers. Job strain, effort/reward imbalance, and workplace social support were measured by the job content questionnaire and effort/reward imbalance questionnaire. These variables were classified into tertiles. PA/PD were measured by self-report based on the mini international neuropsychiatric interview (MINI). Multiple logistic regression was conducted, adjusting for demographic, lifestyle, and health-related covariates. Data from 1965 participants were analyzed. Adjusted odds ratio (OR) of PA/PD was significantly greater for the group with high effort/reward imbalance compared with the group with low effort/reward imbalance (ORs, 2.64 and 2.94, respectively, both P < 0.05). This study found effort/reward imbalance was associated with having PA/PD among Japanese workers.

Chest pain may be due benign diseases but often suggests an association with coronary artery disease, which justifies a quick search for medical care. However, some people have anxiety disorder with symptoms that resemble clearly an acute coronary syndrome. More specifically, during a panic attack an abrupt feeling of fear accompanied by symptoms such as breathlessness, palpitations and chest pain, makes patients believe they have a heart attack and confuse physicians about the diagnosis. The association between panic disorder and coronary artery disease has been extensively studied in recent years and, although some studies have shown anxiety disorders coexisting or increasing the risk of heart disease, one causal hypothesis is still missing. The aim of this systematic review is to present the various ways in which the scientific community has been investigating the relation between chest pain, panic disorder and coronary artery disease.

ETIOLOGY, TRIGGERS AND NEUROCHEMICAL CIRCUITS ASSOCIATED WITH UNEXPECTED, EXPECTED, AND LABORATORY-INDUCED PANIC ATTACKS

Panic disorder (PD) is a severe anxiety disorder that is characterized by recurrent panic attacks (PA), which can be unexpected (uPA, i.e., no clear identifiable trigger) or expected (ePA). Panic typically involves an abrupt feeling of catastrophic fear or distress accompanied by physiological symptoms such as palpitations, racing heart, thermal sensations, and sweating. Recurrent uPA and ePA can also lead to agoraphobia, where subjects with PD avoid situations that were associated with PA. Here we will review recent developments in our understanding of PD, which includes discussions on: symptoms and signs associated with uPA and ePAs; Diagnosis of PD and the new DSM-V; biological etiology such as heritability and gene x environment and gene x hormonal development interactions; comparisons between laboratory and naturally occurring uPAs and ePAs; neurochemical systems that are associated with clinical PAs (e.g. gene associations; targets for triggering or treating PAs), adaptive fear and panic response concepts in the context of new NIH RDoc approach; and finally strengths and weaknesses of translational animal models of adaptive and pathological panic states.

Effects of alprazolam and cannabinoid-related compounds in an animal model of panic attack.

PubMed

Batista, Luara A; Haibara, Andrea S; Schenberg, Luiz C; Moreira, Fabricio A

2017-01-15

Selective stimulation of carotid chemoreceptors by intravenous infusion of low doses of potassium cyanide (KCN) produces short-lasting escape responses that have been proposed as a model of panic attack. In turn, preclinical studies suggest that facilitation of the endocannabinoid system attenuate panic-like responses. Here, we compared the effects of cannabinoid-related compounds to those of alprazolam, a clinically effective panicolytic, on the duration of the escape reaction induced by intravenous infusion of KCN (80μg) in rats. Alprazolam (1, 2, 4mg/kg) decreased escape duration at doses that did not alter basal locomotor activity. URB597 (0.1, 0.3, 1mg/kg; inhibitor of anandamide hydrolysis), WIN55,212-2 (0.1, 0.3, 1mg/kg; synthetic cannabinoid), arachidonoyl-serotonin (1, 2.5, 5mg/kg; dual TRPV1 and anandamide hydrolysis inhibitor), and cannabidiol (5, 10, 20, 40mg/kg; a phytocannabinoid) did not decrease escape duration. Alprazolam also prevented the increase in arterial pressure evoked by KCN, while bradycardia was unchanged. This study reinforces the validity of the KCN-evoked escape as a model of panic attack. However, it does not support a role for the endocannabinoid system in this behavioral response. These results might have implications for the screening of novel treatments for panic disorder.

2017-09-01

Preclinical studies suggest the implication of the adipocyte hormone leptin in anxiety and fear processes. We explored for potential differences regarding plasma leptin, cortisol and the ratio leptin/Body Mass Index (BMI) between 27 medication-free female patients with Panic Disorder (PD) and 42 age-matched female controls, and for potential associations between plasma leptin and psychometric evaluations including number of panic attacks during last week, Clinical Global Impression-Severity of Illness (CGI-S) and Symptoms Checklist-90-Revised (SCL-90-R). Cortisol levels showed no differences between patients and controls, or correlations to leptin or to any clinical features. Both groups demonstrated a strong positive correlation between leptin and BMI and similar leptin and leptin/BMI, despite patients' lower BMI. However, patients -but not controls- demonstrated significant negative correlations of leptin to the 'somatization', 'anxiety', and 'phobic anxiety' SCL-90-R subscales. Moreover, there was a significant negative correlation of leptin and of leptin/BMI ratio to the number of panic attacks during last week, while higher CGI-S was associated with lower leptin/BMI ratio. Our results, limited to PD female patients, suggest that lower leptin serum levels are significantly associated with greater severity of psychopathological manifestations, including number of panic attacks, symptoms of somatization, anxiety and phobic anxiety and overall clinical presentation.

To compare the efficacy and tolerability of moclobemide versus paroxetine for the treatment of depression with comorbid anxiety disorders. Outpatients fulfilling DSM-III-R criteria for major depression or dysthymia and for a co-occurring comorbid anxiety disorder (panic disorder, generalized anxiety disorder or obsessive-compulsive disorder) after a 1-week run-in phase were randomly assigned to open-label moclobemide (300-600 mg/day) or paroxetine (20-40 mg/day) for 4 months. Primary criterion for response was a 50% score reduction from baseline on Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale scores. Mean changes in Clinical Global Impressions Severity of Illness and Improvement Scales (CGI-I) were also used to evaluate treatment response. Of the 123 patients included in the study, 65 were randomly assigned to moclobemide and 58 to paroxetine. At study end, the two treatment groups did not differ significantly in terms of proportion of responders. Treatment group differences emerged when comorbid anxiety diagnoses were considered. In patients with comorbid panic disorder, paroxetine was superior to moclobemide in improving both anxiety and depression (five patients out of 18 in the moclobemide group and nine out of 14 in the paroxetine group were rated as responders according to CGI-I, P = 0.04). Neither medication was superior in treating comorbid generalized anxiety disorder. These findings indicate that both moclobemide and paroxetine are effective for treatment of depression with comorbid anxiety disorders. However, in the subgroup with comorbid panic disorder, paroxetine is more effective than moclobemide in reducing both depressive and anxiety symptoms.

The quality of life of individuals with panic disorder and agoraphobia can be improved by the alleviation of agoraphobia. In other words, examining panic disorder in terms of whether agoraphobia is present is crucial. The current study examined panic disorder from this perspective. Subjects were 253 patients who met the diagnostic criteria for panic disorder (lifetime) according to the Mini International Neuropsychiatric Interview (MINI). Of those patients, 179 had agoraphobia and 74 did not. Statistical analysis was used to examine gender differences in the presence (or absence) of agoraphobia, comorbidities, and the effects of the presence of agoraphobia (severity, assessment of depression, assessment of anxiety, and personality) in these patients. Results indicated gender differences in the presence (or absence) of agoraphobia. Compared to patients without agoraphobia, significantly more patients with agoraphobia were female (p<.001), and had a higher prevalence of comorbidities. Patients with agoraphobia had a higher suicide risk (p<.05), more hypomanic episodes (current) (p<.05), and more frequent episodes of social phobia (p<.05). In addition, patients with agoraphobia had more severe panic disorder and a higher level of neuroticism, sensitivity to anxiety, and trait anxiety [PDSS-J, P&A, NEO-N: p<.01, ASI, STAI (Trait Anxiety): p<.05]. The current findings suggest that when treating a panic disorder, diagnosing the presence of agoraphobia is extremely important. Copyright © 2016 Elsevier Inc. All rights reserved.

Kyol Goeu (‘Wind Overload’) Part I: A Cultural Syndrome of Orthostatic Panic among Khmer Refugees

Certain cultural syndromes seem to increase the risk of panic attacks by generating catastrophic cognitions about symptoms of autonomic arousal. These schemas create a constant anxious scanning of the body, hence facilitating, maintaining, and producing panic. As a case in point, a Khmer fainting syndrome,‘wind overload’ (kyol goeu), results in dire expectations concerning the autonomic symptoms experienced upon standing, thus contributing to the high rate of orthostatically induced panic observed in this population.

Previous research findings have shown positive effects of cognitive-behavioral therapy for primary anxiety disorders as well as for non-primary, co-occurring anxiety disorders. In this study, we analyzed data from an existing randomized controlled trial of intensive treatment for Panic Disorder with or without Agoraphobia (PDA) to examine the effects of the treatment on comorbid psychiatric diagnoses. The overall frequency and severity of aggregated comorbid diagnoses decreased in a group of adolescents who received an 8-day treatment for PDA. Results suggest that an 8-day treatment for PDA can alleviate the symptoms of some specific comorbid clinical diagnoses; specifically Specific Phobias, Generalized Anxiety Disorder, and Social Phobia. These findings suggest that an intensive treatment for PDA is associated with reductions in comorbid symptoms even though disorders other than PDA are not specific treatment targets. PMID:22304887

Emetophobia (fear of vomiting) is an anxiety disorder in which individuals report clinical levels of fear that they may vomit or be exposed to the vomit of others. The prevalence of comorbidity of emetophobia with other conditions has previously only been investigated using self-report instruments. Sixty-four adults with emetophobia participated in an online structured clinical diagnostic interview assessing the presence of emetophobia and other conditions. Higher comorbidity for depression, generalized anxiety disorder, panic disorder, social anxiety disorder and obsessive-compulsive disorder were found in participants compared with general population norms. Emetophobia is commonly comorbid with other anxiety and depressive disorders. Comorbidity rates, when assessed using a structured clinical interview, were lower than previously reported using self-report alone. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message Emetophobia (specific phobia of vomiting) is a clinical fear of vomiting. Individuals with emetophobia show high comorbidity with other anxiety and mood disorders. The most common comorbid conditions were generalized anxiety disorder, panic disorder, hypochondriasis and obsessive-compulsive disorder. Clinicians should ensure that they assess for the presence of comorbid conditions when treating emetophobia. Copyright © 2015 John Wiley & Sons, Ltd.

Panic disorder is commonly prevalent in the population, but the treatment response for panic disorder in clinical practice is much less effective than that in our imagination. Increasing evidence suggested existence of a chronic or remitting-relapsing clinical course in panic disorder. In this systematic review, we re-examine the definition of treatment-resistant panic disorder, and present the potential risk factors related to the treatment resistance, including the characteristics of panic disorder, other psychiatric and physical comorbidities, and psychosocial stresses. Furthermore, we summarize the potential pathophysiologies, such as genetic susceptibility, altered brain functioning, brain-derived neurotrophic factor, and long-term inflammation, to explain the treatment resistance. Finally, we conclude the current therapeutic strategies for treating treatment-resistant panic disorder from pharmacological and non-pharmacological views. Copyright © 2016 Elsevier Inc.

Anxiety is one of the most common comorbidities of epilepsy, which has major detrimental effects on the quality of life. Generalized anxiety disorder (GAD) associated with epilepsy has been receiving most attention. However, several other forms of anxiety reportedly present in patients with epilepsy, including panic disorder (PD). In this study, using an animal model of limbic epilepsy, we examined the interplay between epilepsy and panic-like behavior (PLB). Further, considering the high degree of comorbidity between depression on the one hand, and both epilepsy and PD on the other hand, we studied whether and how the presence of PLB in animals with epilepsy would affect their performance in depression-relevant tests. Fifty-day-old male Wistar rats were subjected to repeated alternating electrical stimulations of the basolateral amygdala (BLA) to induce kindling of limbic seizures, and the dorsal periaqueductal gray (DPAG) to induce panic-like episodes. Seizure susceptibility and panic reaction threshold were examined before the first and 24h after the last stimulation. At the end of the stimulations, the rats were examined in depression-relevant tests: saccharin preference test (SPT) for anhedonia and forced swimming test (FST) for despair/hopelessness. With regard to kindling, BLA+DPAG stimulation induced more profound increase of seizure susceptibility than BLA stimulation alone (evident as the reduction of the afterdischarge threshold and the increase of the afterdischarge duration). With regard to PLB, the BLA+DPAG stimulation exacerbated the severity of panic-like episodes, as compared with the DPAG stimulation alone. Basolateral amygdala stimulation alone had no effects on panic-like reactions, and DPAG stimulation alone did not modify kindling epileptogenesis. Combined stimulation of BLA and DPAG induced depressive-like behavioral impairments. This is the first experimental study showing bidirectional, mutually exacerbating effect of epilepsy and PLB, and the precipitation of depressive-like state by the epilepsy-PLB comorbidity.

Several studies have shown a higher prevalence of somatic illnesses in patients with anxiety disorders, especially cardiopathy, pneumopathy, digestive diseases and cephalea. The aim of this study was to investigate the comorbidity between anxiety disorders and medical illnesses in a group of patients with anxiety disorders compared with patients without psychiatric disorder attended at a primary care clinic and with psychiatric patients without anxiety pathology. Retrospective case-control study comparing 3 groups of patients paired by age and sex. The group of patients with anxiety disorders included 130 patients diagnosed by DSM-IV as panic disorders with/without agoraphobia and agoraphobia without panic attacks. There were 2 control groups: 150 patients without psychiatric disorder attended at primary care and 130 psychiatric patients without anxiety disorder attended at a psychiatric service. Patients with anxiety disorders showed higher risk of medical illnesses than patient without anxiety. Multivariate statistical logistic regression analysis showed that patients with anxiety presented 4.2-fold increase in the risk of cephalea, 3.9 of cardiopathy, 3.8 of osteomuscular disorder and 2-fold increase in the risk of digestive diseases. Patients with anxiety disorders presented higher risk of somatic illness. Similar physiopathology and genetic etiology could explain this association.

The purpose of the study was to contrast first panic attacks (PAs) of patients with panic disorder (PD) with vs. without agoraphobia and to explore differences between first PAs leading to the development of PD and those that remain isolated. Data were drawn from a community survey (N=2259 including 88 isolated PAs and 75 PD cases). An additional sample of 234 PD patients was recruited in a clinical setting. A standardized interview assessed the symptoms of the first PA, context of its occurrence and subsequent coping attempts. Persons who developed PD reported more severe first PAs, more medical service utilization and exposure-limiting coping attempts than those with isolated PAs. The context of the first PA did not differ between PD and isolated PAs. PD with agoraphobia was specifically associated with greater symptom severity and occurrence of first attacks in public. Future research should validate these findings using a longitudinal approach. Copyright © 2014 Elsevier Ltd. All rights reserved.

Psychiatric comorbidities are common in major depressive disorder (MDD). They may worsen outcome and cause economic burden. The primary objective was to examine the prevalence of psychiatric comorbidities in MDD. The secondary objectives were to compare the presence of comorbidities between currently active and past MDD, and between patients with and without suicidal risk. This was a cross-sectional study. A total of 250 patients with lifetime MDD and age ≥18 years were enrolled. The Mini International Neuropsychiatric Interview (MINI), Thai version, was used to confirm MDD diagnosis and classify comorbidities. MDD diagnosis was confirmed in 190, and 60 patients were excluded due to diagnosis of bipolar disorder. Of the 190 MDD patients, 25.8% had current MDD and 74.2% had past MDD. Eighty percent were women. The mean age at enrollment was 50 years, and at MDD onset was 41 years. Most patients were married (53.2%), employed (54.8%), and had ≥12 years of education (66.9%). There were 67 patients (35.3%) with one or more psychiatric comorbidities. Comorbidities included dysthymia (19.5%), any anxiety disorders (21.1%) (panic disorder [6.8%], agoraphobia [5.8%], social phobia [3.7%], obsessive-compulsive disorder [OCD] [4.7%], generalized anxiety disorder [5.3%], and post-traumatic stress disorder [4.2%]), alcohol dependence (0.5%), psychotic disorder (1.6%), antisocial personality (1.1%), and eating disorders (0%). Compared with past MDD, the current MDD group had significantly higher OCD (P<0.001), psychotic disorder (P=0.048), past panic disorder (P=0.017), and suicidal risk (P<0.001). Suicidal risk was found in 32.1% of patients. Patients with suicidal risk had more comorbid anxiety disorder of any type (P=0.019) and psychotic disorder (P=0.032). Several comorbidities were associated with MDD. Patients with active MDD had higher comorbid OCD, psychotic disorder, past panic disorder, and suicidal risk. Patients with suicide risk had higher comorbid anxiety and psychotic disorders.

The current study examined the interactive effects of anxiety sensitivity (AS; fear of anxiety and anxiety-related sensations) and menstrual cycle phase (premenstrual phase vs. follicular phase) on panic-relevant responding (i.e., cognitive and physical panic symptoms, subjective anxiety, and skin conductance level). Women completed a baseline session and underwent a 3-min 10 % CO(2)-enriched air biological challenge paradigm during her premenstrual and follicular menstrual cycle phases. Participants were 55 women with no current or past history of panic disorder recruited from the general community (M (age) = 26.18, SD = 8.9) who completed the biological challenge during both the premenstrual and follicular cycle phases. Results revealed that women higher on AS demonstrated increased cognitive panic symptoms in response to the challenge during the premenstrual phase as compared to the follicular phase, and as compared to women lower on AS assessed in either cycle phase. However, the interaction of AS and menstrual cycle phase did not significantly predict physical panic attack symptoms, subjective ratings of anxiety, or skin conductance level in response to the challenge. Results are discussed in the context of premenstrual exacerbations of cognitive, as opposed to physical, panic attack symptoms for high AS women, and the clinical implications of these findings.

Increased heartbeat perception accuracy (HBP-accuracy) may contribute to the pathogenesis of Panic Disorder (PD) without or with Agoraphobia (PDA). Extant research suggests that HBP-accuracy is a rather stable individual characteristic, moreover predictive of worse long-term outcome in PD/PDA patients. However, it remains still unexplored whether HBP-accuracy adversely affects patients' short-term outcome after structured cognitive behaviour therapy (CBT) for PD/PDA. To explore the potential association between HBP-accuracy and the short-term outcome of a structured brief-CBT for the acute treatment of PDA. We assessed baseline HBP-accuracy using the "mental tracking" paradigm in 25 consecutive medication-free, CBT-naive PDA patients. Patients then underwent a structured, protocol-based, 8-session CBT by the same therapist. Outcome measures included the number of panic attacks during the past week, the Agoraphobic Cognitions Questionnaire (ACQ), and the Mobility Inventory-Alone subscale (MI-alone). No association emerged between baseline HBP-accuracy and posttreatment changes concerning number of panic attacks. Moreover, higher baseline HBP-accuracy was associated with significantly larger reductions in the scores of the ACQ and the MI-alone scales. Our results suggest that in PDA patients undergoing structured brief-CBT for the acute treatment of their symptoms, higher baseline HBP-accuracy is not associated with worse short-term outcome concerning panic attacks. Furthermore, higher baseline HBP-accuracy may be associated with enhanced therapeutic gains in agoraphobic cognitions and behaviours.

Some panicogens also elicit short-lived panic-like states in healthy man. This offers the opportunity to assess the anti-panic action of drugs in proof-of-concept studies. However, from current data it is still unclear whether experimental panic in healthy man is a valid translational model. Most such studies in healthy volunteers have been performed using a cholecystokinin tetrapeptide (CCK-4) challenge. While CCK-4 panic was blocked by alprazolam pretreatment, escitalopram showed negative results in healthy man. Preliminary findings on novel investigational drugs and a few problematic results will be reviewed. Small sample sizes in many panic provocation studies, lack of dose-response aspects, and still-insufficient knowledge about the biological underpinning of experimental and spontaneous panic limit the interpretation of existing findings and should inspire further research.

Twenty-five panic disorder (PD) patients, 19 social phobics (SP), and 20 healthy controls (HC) sat quietly for 15 minutes, rating their anxiety and dyspnea every 30 seconds while respiratory, cardiovascular, and electrodermal responses were recorded. No panic attacks were reported. For self-reported anxiety and dyspnea, within-subject variability over time was higher in PD than in SP or HC. In PD within-subject correlations across 30-second epochs were significant for (a) self-reported anxiety versus dyspnea, end-tidal pCO2, minute volume, duty cycle, skin conductance level, and interbeat interval, and for (b) dyspnea versus end-tidal pCO2, minute volume, tidal volume, and inspiratory flow rate. Several positive or negative correlations were greater in PD than in other groups. Thus in PD, experienced anxiety and dyspnea are temporally unstable but are correlated with each other and with fluctuations in respiratory and autonomic variables, even in the absence of panic attacks.

Visuospatial and Mathematical Dysfunction in Major Depressive Disorder and/or Panic Disorder: A Study of Parietal Functioning

PubMed Central

Nelson, Brady D.; Shankman, Stewart A.

2015-01-01

The parietal cortex is critical for several different cognitive functions, including visuospatial processing and mathematical abilities. There is strong evidence indicating parietal dysfunction in depression. However, it is less clear whether anxiety is associated with parietal dysfunction, and whether comorbid depression and anxiety is associated with greater impairment. The present study compared participants with major depression (MDD), panic disorder (PD), comorbid MDD/PD, and controls on neuropsychological measures of visuospatial processing, Judgment of Line Orientation (JLO), and mathematical abilities, Wide Range Achievement Arithmetic (WRAT-Arithmetic). Only comorbid MDD/PD was associated with decreased performance on JLO, whereas all psychopathological groups exhibited comparably decreased performance on WRAT-Arithmetic. Furthermore, the results were not accounted for by other comorbid disorders, medication use, or psychopathology severity. The present study suggests comorbid depression and anxious arousal is associated with impairment in visuospatial processing and provides novel evidence indicating mathematical deficits across depression and/or anxiety. Implications for understanding parietal dysfunction in internalizing psychopathology are discussed. PMID:25707308

The purpose of the present investigation was to examine the psychological impact of remote exposure to the events and aftermath of the terrorist attacks in the USA on September 11th, 2001, and to assess what differences, if any, exist between individuals classified with probable panic disorder and those without. Telephone interviews were conducted with 122 residents of the capital city of the Canadian prairie province of Saskatchewan in spring 2002 in order to gather information regarding current mood, fears and avoidance behaviours as well as current post-traumatic stress disorder symptoms specific to September 11th. Consistent with previous findings and despite the remote nature of exposure, results indicated that the psychological well-being and behaviour of participants with probable panic disorder was more adversely affected by the events and aftermath of September 11th than those without panic disorder. These results suggest that remote viewing of traumatic events can have a significant and lingering impact on psychological well-being and behaviour and that these effects are more pronounced in those with panic disorder. Implications of the findings and future research directions are discussed.

Mood, cognitive, and behavioural changes have been reported with deep brain stimulation (DBS) in the thalamus, globus pallidus interna, and anterior limb of the internal capsule/nucleus accumbens region. To investigate panic and fear resulting from DBS. Intraoperative DBS in the region of the right and then left anterior limb of the internal capsule and nucleus accumbens region was undertaken to treat a 52 year old man with treatment refractory obsessive-compulsive disorder (OCD). Mood, anxiety, OCD, alertness, heart rate, and subjective feelings were recorded during intraoperative test stimulation and at follow up programming sessions. DBS at the distal (0) contact (cathode 0-, anode 2+, pulse width 210 ms, rate 135 Hz, at 6 volts) elicited a panic attack (only seen at the (0) contact). The patient felt flushed, hot, fearful, and described himself as having a "panic attack." His heart rate increased from 53 to 111. The effect (present with either device) was witnessed immediately after turning the device on, and abruptly ceased in the off condition DBS of the anterior limb of the internal capsule and nucleus accumbens region caused severe "panic." This response may result from activation of limbic and autonomic networks.

Side effects to antidepressant medication can affect the efficacy of treatment, but few predictors foretell who experiences side effects and which side effects they experience. This secondary data analysis examined whether depressed patients with comorbid panic disorder were more likely to experience side effects than those without panic disorder. The study also examined whether greater burden of side effects predicted a poorer treatment course for patients with panic disorder than those without panic disorder. To examine the specificity of these effects, analyses also examined 2 other anxiety disorders-social phobia and generalized anxiety disorder (GAD). Between 2002 and 2006, a large sample (N = 808) of chronically depressed individuals (assessed using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders [SCID-IV]) received antidepressants according to a predetermined algorithm for 12 weeks. Every 2 weeks, depressive symptoms (per the Hamilton Depression Rating Scale) and side effects (specific side effects as well as several indicators of side effect burden) were assessed. Lifetime diagnosis of panic disorder (assessed using the SCID-IV) at baseline was associated with higher likelihood of gastrointestinal (OR = 1.6 [95% CI, 1.0-2.6]), cardiac (OR = 1.8 [95% CI, 1.1-3.1]), neurologic (OR = 2.6 [95% CI, 1.6-4.2]), and genitourinary side effects (OR = 3.0 [95% CI, 1.7-5.3]) during treatment. Increases in side effect frequency, intensity, and impairment over time were more strongly associated with increases in depressive symptoms for patients with panic disorder compared to those without panic disorder. Neither social phobia nor GAD was associated with these effects. Potentially due to heighte​ned interoceptive awareness of changes in their body, chronically depressed individuals with panic disorder may be at greater risk than those without panic disorder for antidepressant side effects and to experience a worsening of depressive symptoms as a result of these side effects over time.

It is known that there is a high prevalence of certain anxiety disorders among schizophrenic patients, especially panic disorder and social phobia. However, the neural underpinnings of the comorbidity of such anxiety disorders and schizophrenia remain unclear. Our study aims to determine the neuroanatomical basis of the co-occurrence of schizophrenia with panic disorder and social phobia. Voxel-based morphometry was used in order to examine brain structure and to measure between-group differences, comparing magnetic resonance images of 20 anxious patients, 20 schizophrenic patients, 20 schizophrenic patients with comorbid anxiety, and 20 healthy control subjects. Compared to the schizophrenic patients, we observed smaller grey-matter volume (GMV) decreases in the dorsolateral prefrontal cortex and precentral gyrus in the schizophrenic-anxiety group. Additionally, the schizophrenic group showed significantly reduced GMV in the dorsolateral prefrontal cortex, precentral gyrus, orbitofrontal cortex, temporal gyrus and angular/inferior parietal gyrus when compared to the control group. Our findings suggest that the comorbidity of schizophrenia with panic disorder and social phobia might be characterized by specific neuroanatomical and clinical alterations that may be related to maladaptive emotion regulation related to anxiety. Even thought our findings need to be replicated, our study suggests that the identification of neural abnormalities involved in anxiety, schizophrenia and schizophrenia-anxiety may lead to an improved diagnosis and management of these conditions.

No studies of psychotherapies for panic disorder (PD) have examined effects on comorbid personality disorders (PersD), yet half such patients have a PersD. In a randomized trial for PD with and without agoraphobia comparing Cognitive-Behavioral Therapy (CBT) and Panic-Focused Psychodynamic Psychotherapy (PFPP), PersD was assessed pre-to-post treatment with the Structured Clinical Interview for the Diagnosis of Axis-II Disorders (SCID-II). For patients completing therapy (n = 118, 54 with PersD), covariance between panic and SCID-II criteria improvements was analyzed. SCID-II diagnostic remission and recovery were evaluated. Comparative efficacy of PFPP versus CBT for improving PersD was analyzed both for the average patient, and as a function of PersD severity. 37 and 17% of PersD patients experienced diagnostic PersD remission and recovery, respectively. Larger reductions in PersD were related to more panic improvement, with a modest effect size (r = 0.28). Although there was no difference between treatments in their ability to improve PersD for the average patient (d = 0.01), patients meeting more PersD criteria did better in PFPP compared to CBT (P = .007), with PFPP being significantly superior at 11 criteria and above (d = 0.66; 3 more criteria lost). PersD presenting in the context of primary PD rarely resolves during psychotherapies focused on PD, and change in PersD only moderately tracks panic improvements, indicating non-overlap of the constructs. Patients receiving panic-focused psychotherapies may require additional treatment for their PersD. PFPP may be superior at improving severe PersD, but replication of this finding is required. © 2017 Wiley Periodicals, Inc.

Previous studies indicated that panic disorder is correlated with erectile dysfunction (ED). The primary aim of this study was to explore the incidence rate of ED among panic disorder patients in an Asian country. The secondary aim was to compare the risk of ED in panic disorder patients that were treated with different kinds of antidepressants, and to explore the possible mechanism between these two disorders. We identified 1393 male patients with newly diagnosed panic disorder from the Taiwan's National Health Insurance Database. Four matched controls per case were selected for the study group by propensity score. After adjusting for age, obesity and comorbidities, the panic disorder patients had a higher hazard ratio of ED diagnosis than the controls, especially among the untreated panic disorder patients. This retrospective dynamic cohort study supports the link between ED and prior panic disorder in a large sample of panic disorder patients. This study points out the need of early antidepressant treatment for panic disorder to prevent further ED. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The effect of Korean-group cognitive behavioural therapy among patients with panic disorder in clinic settings.

2017-02-01

WHAT IS KNOWN ON THE SUBJECT?: Panic disorder patients display various panic-related physical symptoms and catastrophic misinterpretation of bodily sensations, which lower their quality of life by interfering with daily activities. Cognitive behavioural therapy (CBT) is a useful strategy for panic disorder patients to manage symptoms associated with inaccurate cognitive interpretation of situations resulting from the patient's cognitive vulnerability. In South Korea, however, despite the increasing prevalence of panic disorder, CBT is not a common element of nursing care plans for panic disorder patients. Moreover, few Korean researchers have attempted to assess the effects of CBT on such patients. WHAT THIS PAPER ADD TO EXISTING KNOWLEDGE?: In a strategy combining CBT and routine treatments, patients with panic disorder can experience greater positive effects in the acute treatment phase than those they experience when receiving only routine treatment. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health professionals, especially psychiatric nurses in local clinics who operate most special mental health programmes for panic disorder patients, should apply a panic disorder management programme that integrates CBT and routine treatments. The integrated approach is more effective for reducing the number of panic attacks and cognitive misinterpretation in patients than providing routine treatment alone. For patients with panic disorder, the objective of CBT is to understand the relationship between psychological panic disorder sensations, emotions, thoughts and behaviours. Therefore, nurses can help patients address and improve biological, social and psychological aspects of physical health problems as well as help them improve their coping skills in general. Introduction In panic disorder, sensitivity to bodily sensations increases due to the patient's cognitive vulnerability. Cognitive behavioural therapy (CBT) can help to decrease sensitivity to bodily sensations by correcting these cognitive distortions by controlling negative thoughts and panic attacks. Aims This study verified whether group CBT is more effective than treatment as usual (TAU) in South Korean patients with panic disorder. Methods The study participants consisted of 76 panic disorder patients. Patients in the therapy condition attended sessions once a week for a total of 12 sessions in addition to drug treatment. Results In the therapy condition, there were significant decreases in panic-related bodily sensations and ranking and belief scores for catastrophic misinterpretation of external events. Discussion Group CBT, in comparison to TAU, decreases panic and agoraphobia symptom severity in South Korean patients with panic disorder. Our study provides evidence for the effectiveness of a panic disorder management programme that integrates group CBT and traditional pharmacotherapeutic treatment for patients with panic disorder. Implications for Practice The cognitive behavioural approach is needed to reduce panic and agoraphobia symptoms for hospitalized patients with panic disorder more than activity therapies, medications and supportive counselling by doctors and nurses. © 2016 John Wiley & Sons Ltd.

Objective The authors sought to observe the long-term clinical course of anxiety disorders over 12 years and to examine the influence of comorbid psychiatric disorders on recovery from or recurrence of panic disorder, generalized anxiety disorder, and social phobia. Method Data were drawn from the Harvard/Brown Anxiety Disorders Research Program, a prospective, naturalistic, longitudinal, multicenter study of adults with a current or past history of anxiety disorders. Probabilities of recovery and recurrence were calculated by using standard survival analysis methods. Proportional hazards regression analyses with time-varying covariates were conducted to determine risk ratios for possible comorbid psychiatric predictors of recovery and recurrence. Results Survival analyses revealed an overall chronic course for the majority of the anxiety disorders. Social phobia had the smallest probability of recovery after 12 years of follow-up. Moreover, patients who had prospectively observed recovery from their intake anxiety disorder had a high probability of recurrence over the follow-up period. The overall clinical course was worsened by several comorbid psychiatric conditions, including major depression and alcohol and other substance use disorders, and by comorbidity of generalized anxiety disorder and panic disorder with agoraphobia. Conclusions These data depict the anxiety disorders as insidious, with a chronic clinical course, low rates of recovery, and relatively high probabilities of recurrence. The presence of particular comorbid psychiatric disorders significantly lowered the likelihood of recovery from anxiety disorders and increased the likelihood of their recurrence. The findings add to the understanding of the nosology and treatment of these disorders. PMID:15930067

Panic disorder is a common mental disease with high psychiatric comorbidity. It is considered that a combination of genetic predisposition and a special psychic vulnerability plays a key role in the occurrence of panic disorder. Clinically proven efficacy in the treatment of panic disorder have benzodiazepines, tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors and selective serotonin and norepinephrine reuptake inhibitors; antidepressants from other pharmaceutical groups are also used. Selective serotonin reuptake inhibitors are the first line medicines in the treatment of panic disorder. Atypical antipsychotics may be used for the therapy augmentation in addition to first line drugs. Psychotherapy is used along with medications, and a combination of pharmacotherapy and cognitive behavioral therapy is the best method of treatment.

To explore the effects of Chinese medicine prescription Zuogui Pill (, ZGP) on monoamine neurotransmitters and sex hormones in climacteric rats with induced panic attacks. Forty-eight climacteric female rats were randomized into 6 groups with 8 rats in each group: the control group, the model group, the low-, medium- and high-dose ZGP groups and the alprazolam group. Rats in the low-, medium- and high-dose ZGP groups were administered 4.725, 9.45, or 18.9 g/kg ZGP by gastric perfusion, respectively. The alprazolam group was treated by gastric perfusion with 0.036 mg/kg alprazolam. The control and model groups were treated with distilled water. The animals were pretreated once daily for 8 consecutive weeks. The behaviors of rats in the open fifield test and the elevated T-maze (ETM) were observed after induced panic attack, and the levels of brain monoamine neurotransmitters and the plasma levels of sex hormones were measured. Compared with the control group, the mean ETM escape time and the levels of 5-hydroxytryptamine (5-HT) and noradrenalin (NE) of the model group were signifificantly reduced (P<0.05), Compared with the model group, the mean ETM escape time and the 5-HT and NE levels of all the ZGP groups increased signifificantly (P<0.05 or P<0.01). However, no signifificant difference was observed in the levels of sex hormones between the groups. Pretreatment with ZGP in climacteric rats may improve the behavior of panic attack, which may be related to increased 5-HT and NE in the brain.

People with anxiety disorders occasionally report fears about losing control of basic bodily functions in public. These anxieties often occur in the absence of physical disorder and have previously been recognized as "obsessive" anxieties reflecting a preoccupation with loss of bowel/bladder control. Motivated by our observations of the non-trivial occurrence of such anxieties in our clinical practice we sought to fill a gap in the current understanding of "bowel/bladder-control anxieties". Eligible participants completed an internet survey. Bowel/bladder-control anxieties (n = 140) tended to emerge in the mid to late 20s and were associated with high levels of avoidance and functional impairment. There was a high prevalence of panic attacks (78%); these were especially prevalent among those with bowel-control anxiety. Of those with panic attacks, 62% indicated that their main concern was being incontinent during a panic attack. Significantly, a proportion of respondents (~16%) reported actually being incontinent during a panic attack. Seventy percent of participants reported intrusive imagery related to loss of bowel/bladder control. Intrusion-related distress was correlated with agoraphobic avoidance and general role impairment. Some differences were noted between those with predominantly bowel-, predominantly bladder- and those with both bowel and bladder-control anxieties. This preliminary characterization indicates that even in a non-treatment seeking community sample, bowel/bladder-control anxieties are associated with high levels of distress and impairment. Further careful characterization of these anxieties will clarify their phenomenology and help us develop or modify treatment protocols in a way that takes account of any special characteristics of such viscerally-centred phobic syndromes.

In the current review, we reconceptualize a categorical diagnosis-panic disorder and agoraphobia-in terms of two constructs within the domain "negative valence systems" suggested by the Research Domain Criteria initiative. Panic attacks are considered as abrupt and intense fear responses to acute threat arising from inside the body, while anxious apprehension refers to anxiety responses to potential harm and more distant or uncertain threat. Taking a dimensional view, panic disorder with agoraphobia is defined with the threat-imminence model stating that defensive responses are dynamically organized along the dimension of the proximity of the threat. We tested this model within a large group of patients with panic disorder and agoraphobia (N = 369 and N = 124 in a replication sample) and found evidence that panic attacks are indeed instances of circa strike defense. This component of the defensive reactivity was related to genetic modulators within the serotonergic system. In contrast, anxious apprehension-characterized by attentive freezing during postencounter defense-was related to general distress and depressive mood, as well as to genetic modulations within the hypothalamic-pituitary-adrenal (HPA) axis. Patients with a strong behavioral tendency for active and passive avoidance responded better to exposure treatment if the therapist guides the patient through the exposure exercises. © 2016 Society for Psychophysiological Research.

Despite the current treatments available for panic disorder (PD), as many as one-third of patients have persistent and treatment-resistant panic attacks. Vortioxetine is an approved medicine for major depressive disorder and has been shown to have anxiolytic properties. The purpose of this study was to evaluate its efficacy and safety in an adult population with a diagnosis of PD. The study design was open label with flexible dose strategies (5, 10, or 20 mg) with a treatment period of 10 weeks. 27 male and female subjects aged between 18 and 60 years, who met DSM-IV criteria for PD with or without agoraphobia, or who had a Panic Disorder Severity Scale (PDSS) score > 8 at baseline were enrolled. Statistical significance was established by the Student's T test. A statistically significant decrease in the occurrence of panic attacks was measured with the PDSS with vortioxetine. In addition, a moderate improvement in the quality of life and no significant side effects were observed using the Quality-of-Life Scale and Monitoring of Side Effects Scale, respectively. These results provide some support for the use of vortioxetine in the management of panic disorder. Trial registration ClinicalTrials.gov ID#: NCT02395510.

An evaluation was made of the influence of different psychiatric co-morbidities on the symptoms of the disorder popularly known as "ataque de nervios" (nervous breakdown) among the US Hispanic population. Using a self-completed instrument designed specially for both traditional nervous breakdown and for panic symptoms, and structured or semi-structured psychiatric interviews for Axis I disorders, and evaluation was made of Hispanic subjects who sought treatment for anxiety in a clinic (n = 156). This study centered on 102 subjects who presented symptoms of "nervous breakdown" and comorbidity with panic disorder, other anxiety disorders, or affective disorder. Variations in co-morbidity with "nervous breakdown" enabled the identification of different patterns of "nervous breakdown" presenting symptoms. Individuals with "nervous breakdown" and panic disorder characteristically expressed a greater sense of asphyxiation, fear of dying, and growing fear (panic-like) during their breakdowns. Subjects with "nervous breakdown" and affective disorder had a greater sensation of anger and more tendency toward screaming and aggressive behavior such as breaking things during the breakdown (emotional anger). Finally, subjects with "nervous breakdown" and co-morbidity with another anxiety disorder had fewer "paniclike" or "emotional anger" symptoms. These findings suggest that: a) the widely used term "nervous breakdown" is a popular label for different patterns of loss of emotional control; b) the type of loss of emotional control is influenced by the associated psychiatric disorder; and c) the symptoms characteristics of the "nervous breakdown" can be useful clinical markers for associated psychiatric disorders. Future research is needed to determine whether the known Hispanic entity "ataque de nervios" is simply a popular description for different aspects of well-known psychiatric disorders, or if it reflects specific demographic, environmental, personality and/or clinical characteristics of the population.

"But it might be a heart attack": intolerance of uncertainty and panic disorder symptoms.

Panic disorder models describe interactions between feared anxiety-related physical sensations (i.e., anxiety sensitivity; AS) and catastrophic interpretations therein. Intolerance of uncertainty (IU) has been implicated as necessary for catastrophic interpretations in community samples. The current study examined relationships between IU, AS, and panic disorder symptoms in a clinical sample. Participants had a principal diagnosis of panic disorder, with or without agoraphobia (n=132; 66% women). IU was expected to account for significant variance in panic symptoms controlling for AS. AS was expected to mediate the relationship between IU and panic symptoms, whereas IU was expected to moderate the relationship between AS and panic symptoms. Hierarchical linear regressions indicated that IU accounted for significant unique variance in panic symptoms relative to AS, with comparable part correlations. Mediation and moderation models were also tested and suggested direct and indirect effects of IU on panic symptoms through AS; however, an interaction effect was not supported. The current cross-sectional evidence supports a role for IU in panic symptoms, independent of AS. Copyright © 2014 Elsevier Ltd. All rights reserved.

The association between obsessive compulsive disorder and obsessive compulsive personality disorder: prevalence and clinical presentation.

2013-09-01

The relationship between Obsessive Compulsive Disorder (OCD) and Obsessive Compulsive Personality Disorder (OCPD) has been the subject of interest for some time due to the historical assumption that OCPD causes OCD. This study systematically examined the association between OCD and OCPD in terms of prevalence and clinical presentation. The specificity of the association between OCD and OCPD was investigated relative to another axis I anxiety disorder (Panic disorder). Data for this study were drawn from measures taken at initial assessment at a specialist treatment centre for anxiety disorders. Of the 359 participants included in this study, 189 had a principal diagnosis of OCD, while 170 had a principal diagnosis of Panic disorder. Measures included SCID I and II interview modules and self-report measures of anxiety, depression, and OCD syptomatology. Significantly elevated rates of OCPD were found in OCD relative to Panic disorder. Regardless of axis I disorder, individuals with comorbid OCPD reported more severe depression relative to those without. Participants with both OCD and OCPD had greater self-reported OCD symptom severity, doubting, ordering, and hoarding symptoms at assessment relative to those without OCPD. Participants with OCD and comorbid OCPD also reported significantly higher levels of alcohol consumption. There appears to be a significant and specific association between OCD and OCPD. Co-occurring OCD and OCPD is associated with greater severity of impairment in terms of certain OCD symptoms. The significant and specific association between OCD and OCPD suggests that OCPD occurs more frequently with OCD than previously suggested. A comorbid OCPD diagnosis is associated with a greater degree of depression, regardless of axis I disorder, either OCD or Panic disorder. This is an important consideration, as depression can interfere with therapeutic progress (Foa, 1979). Participants with OCD and OCPD had greater self-reported OCD severity, along with doubting, ordering, and hoarding symptoms, relative to those without OCPD. In clinical practice, where OCD symptoms are severe, and the primary OCD symptoms include doubting, ordering, and hoarding, this may indicate a need to assess for comorbid OCPD. This may be useful in terms of including relevant information in formulation with the patient, and in addressing these issues in treatment. There may have been a sampling issue, as the study compared patients from a specialist clinic for the treatment of OCD and Panic disorder. Furthermore, OCD referrals were primary, secondary, or tertiary, whereas Panic disorder referrals were primary or secondary from the immediate catchment area only. This suggests the possibility of greater severity of the OCD sample relative to Panic disorder patients. All participants who met criteria for OCD were assessed for OCPD regardless of whether or not this was indicated by the SCID II screener self-report measure, while participants with Panic disorder were interviewed for OCPD only if indicated by the SCID-II screener. Had participants with Panic disorder been assessed for OCPD regardless of whether or not this was indicated by the SCID-II screener, there is a possibility that a higher rate of OCPD in the Panic disorder sample may have been found. © 2013 The British Psychological Society.

Panic disorder patients are exquisitely and specifically sensitive to hypercapnia. The demonstration that carbon dioxide provokes panic in fear-unresponsive amygdala-calcified Urbach-Wiethe patients emphasizes that panic is not fear nor does it require the activation of the amygdala. This is consonant with increasing evidence suggesting that panic is mediated caudally at midbrain's dorsal periaqueductal gray matter (DPAG). Another startling feature of the apparently spontaneous clinical panic is the counterintuitive lack of increments in corticotropin, cortisol and prolactin, generally considered 'stress hormones'. Here we show that the stress hormones are not changed during DPAG-evoked panic when escape is prevented by stimulating the rat in a small compartment. Neither did the corticotropin increase when physical exertion was statistically adjusted to the same degree as non-stimulated controls, as measured by lactate plasma levels. Conversely, neuroendocrine responses to foot-shocks were independent from muscular effort. Data are consonant with DPAG mediation of panic attacks. Copyright © 2015 Elsevier Ltd.

The fear of fear present in agoraphobics can be broken down into a fear of the body sensations associated with the panic attacks that plague agoraphobics and maladaptive thoughts about the possible consequences of panic. In a retrospective examination of clinical files, 32 agoraphobic patients were compared to 36 patients with simple social…

Researchers have been using the electroencephalogram to better understand the cognitive and neurobiological bases of panic disorder (PD) through the P300 component; this is an electric potential of the cerebral cortex that is generated in response to external sensorial stimuli and which involves more complex neurophysiological processes related to stimulus interpretation; it is then used to investigate possible alterations in the information processing and attention of patients suffering from this disorder. Aiming to verify the results found by experimental articles already published about P300 in PD patients and the information processing differences between PD patients and healthy controls, a systematic review of the PubMed and Institute for Scientific Information databases was conducted. The selection criterion involved those articles, written in English, which referred to an experimental research that focused on the P300 component, with a sample composed of PD (or panic attacks) patients. Seven articles were found that fit the selected criteria. Most of the articles show that these patients suffer from: impaired information processing and attention, an inability to automatically respond to new stimuli, and impaired interpretation of internal and external stimuli related to the disorder. Such impairment may be related to an unspecified dysfunction in the limbic-reticular structures, which would affect: active, focused and short-term attention, working and short-term memory, recognition and decision making. Some limitations were highlighted, such as the use of small samples and possible comorbidity with other disorders, which did not allow clearer results. This research can contribute to understand the neurobiological differences of PD patients and develop treatments based on such evidence.

Background Anxiety disorders are common problems that result in enormous suffering and economic costs. The efficacy of Web-based self-help approaches for anxiety disorders has been demonstrated in a number of controlled trials. However, there is little data regarding the patterns of use and effectiveness of freely available Web-based interventions outside the context of controlled trials. Objective To examine the use and longitudinal effectiveness of a freely available, 12-session, Web-based, cognitive behavioral therapy (CBT) program for panic disorder and agoraphobia. Methods Cumulative anonymous data were analyzed from 99695 users of the Panic Center. Usage statistics for the website were examined and a longitudinal survey of self-reported symptoms for people who registered for the CBT program was conducted. The primary outcome measures were self-reported panic-attack frequency and severity at the beginning of each session (sessions 2-12). Results Between September 1, 2002 and February 1, 2004, there were 484695 visits and 1148097 page views from 99695 users to the Panic Center. In that same time period, 1161 users registered for the CBT program. There was an extremely high attrition rate with only 12 (1.03%) out of 1161 of registered users completing the 12-week program. However, even for those who remained in the program less than 12 weeks we found statistically significant reductions (P<.002) in self-reported panic attack frequency and severity, comparing 2 weeks of data against data after 3, 6, or 8 weeks. For example, the 152 users completing only 3 sessions of the program reduced their average number of attacks per day from 1.03 (week 2) to 0.63 (week 3) (P<.001). Conclusions Freely available Web-based self-help will likely be associated with high attrition. However, for the highly self-selected group who stayed in the program, significant improvements were observed. PMID:15829479

A Proposal for a Dimensional Classification System Based on the Shared Features of the DSM-IV Anxiety and Mood Disorders: Implications for Assessment and Treatment

PubMed Central

Brown, Timothy A.; Barlow, David H.

2010-01-01

A wealth of evidence attests to the extensive current and lifetime diagnostic comorbidity of the DSM-IV anxiety and mood disorders. Research has shown that the considerable cross-sectional covariation of DSM-IV emotional disorders is accounted for by common higher-order dimensions such as neuroticism/behavioral inhibition (N/BI) and low positive affect/behavioral activation. Longitudinal studies have indicated that the temporal covariation of these disorders can be explained by changes in N/BI and in some cases, initial levels of N/BI are predictive of the temporal course of emotional disorders. Moreover, the marked phenotypal overlap of the DSM-IV anxiety and mood disorder constructs is a frequent source of diagnostic unreliability (e.g., temporal overlap in the shared features of generalized anxiety disorder and mood disorders, situation specificity of panic attacks in panic disorder and specific phobia). Although dimensional approaches have been considered as a method to address the drawbacks associated with the extant prototypical nosology (e.g., inadequate assessment of individual differences in disorder severity), these proposals do not reconcile key problems in current classification such as modest reliability and high comorbidity. The current paper considers an alternative approach that emphasizes empirically supported common dimensions of emotional disorders over disorder-specific criteria sets. The selection and assessment of these dimensions are discussed along with how these methods could be implemented to promote more reliable and valid diagnosis, prognosis, and treatment planning. For instance, the advantages of this classification system are discussed in context of current transdiagnostic treatment protocols that are efficaciously applied to a variety of disorders by targeting their shared features.

Terrorism and dispelling the myth of a panic prone public.

Governments and commentators perceive the public to be prone to panic in response to terrorist attacks--conventional or involving chemical, biological or radiological weapons. Evidence from five such incidents suggests that the public is not prone to panic, although people can change their behaviours and attitudes to reduce the risk of themselves being exposed to a terrorist incident. Behavioural responses may be divided into acts of omission, such as not making unnecessary journeys, and acts of commission, such as taking prophylactic medication despite the inherent risk of side effects. Evidence suggests that the public are aware of these differences, and tend to adopt responses proportionate to the risk. Drawing upon the literature in the social and natural sciences, our discussion encompasses differing risk perceptions of terrorist threats and consequences of attacks. How do fear and anxiety interact with behavioural responses to amplify or attenuate perceptions that can be modified through risk communication undertaken by authorities?

Atomoxetine, a selective norepinephrine inhibitor, is effective in comorbid anxiety and attention deficit hyperactivity disorder, however its role in panic disorder is unknown. We are presenting a case of panic disorder, who initially partially responded to clonazepam. When clonazepam was added with sertraline, escitalopram, desvenlafaxin, she did not improve significantly until paroxetine was added. When clonazepam-paroxetine combination was added with propranolol, etizolam, olanzepine, risperidone and amisulpride the symptom remission did not occur until a trial of Atomoxetine was done.

To investigate the prevalence and correlates of comorbid psychiatric disorders and suicidal risk in community-based adolescents with chronic daily headache (CDH). We identified and recruited 122 adolescents with CDH from a non-referral student sample (n = 7,900). CDH subtypes were classified according to the most updated criteria of the International Classification of Headache Disorders, 2nd edition (ICHD-2). An in-person psychiatric interview was performed with each subject with CDH to assess depressive and anxiety disorders and suicidal risk based on the Mini-International Neuropsychiatric Interview-Kid (MINI-Kid). Clinical correlates and impacts were investigated. A total of 121 subjects (31 male/90 female, mean age 13.8 years) finished the psychiatric interview. Fifty-seven subjects (47%) had > or =1 assessed psychiatric comorbidity with major depression (21%) and panic disorder (19%) as the two most common diagnoses. Current suicidal risk was assessed as high (score > or = 10) in 20% of subjects. Female gender and older age were associated with depressive disorders. Presence of migraine was associated with psychiatric comorbidities (OR = 3.5, p = 0.002). The associations with psychiatric disorders were stronger for migraine with aura than for migraine without aura. Migraine with aura also independently predicted a high suicidal risk (score > or = 10) (adjusted OR = 6.0, p = 0.028). In contrast, CDH subtypes, headache frequencies, or medication overuse were not correlated. Comorbid psychiatric disorders were not related to physician consultations or more days of sick leave. This community-based study showed high comorbidity of psychiatric disorders and suicidal risk in adolescents with chronic daily headache. The presence of migraine attacks, especially migraine with aura, was the major predictor for these associations.

Determining how personality disorder traits and panic disorder and/or agoraphobia relate longitudinally is an important step in developing a comprehensive understanding of the etiology of panic/agoraphobia. In 1981, a probabilistic sample of adult (≥ 18 years old) residents of east Baltimore were assessed for Axis I symptoms and disorders using the Diagnostic Interview Schedule (DIS); psychiatrists re-evaluated a sub-sample of these participants and made Axis I diagnoses, as well as ratings of individual DSM-III personality disorder traits. Of the participants psychiatrists examined in 1981, 432 were assessed again in 1993–1996 using the DIS. Excluding participants who had baseline panic attacks or panic-like spells from the risk groups, baseline timidity (avoidant, dependent, and related traits) predicted first-onset DIS panic disorder or agoraphobia over the follow-up period. These results suggest that avoidant and dependent personality traits are predisposing factors, or at least markers of risk, for panic disorder and agoraphobia - not simply epiphenomena.

The aim of the study was to investigate whether polymorphisms in the preproghrelin gene are associated with anxiety disorders, such as panic disorder, in humans. Panic disorder is a severe anxiety disorder, characterized by sudden attacks of intense fear or anxiety in combination with somatic symptoms. The preproghrelin gene codes for two gut-derived circulating peptides that have been linked to anxiety-like behaviour in rodents: ghrelin (an orexigenic, pro-obesity hormone) and obestatin. In the present study, we genotyped three missense mutations in the preproghrelin gene in 215 patients suffering from panic disorder and in 451 controls. The A allele of the rs4684677 polymorphism was significantly associated with panic disorder, while there were no significant associations with the two other polymorphisms studied. We conclude that the rs4684677 (Gln90Leu) polymorphism in the preproghrelin gene may be associated with increased risk of panic disorder. It will be important to confirm these findings in additional panic disorder patient groups. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Peritraumatic panic attacks and health outcomes two years after psychological trauma: implications for intervention and research.

PubMed

Boscarino, Joseph A; Adams, Richard E

2009-05-15

Several studies have suggested that experiencing a peritraumatic panic attack (PPA) during a traumatic event predicts future mental health status. Some investigators have suggested that this finding has psychotherapeutic significance. We assessed the hypothesis that PPA was not related to longer-term health status after event exposure, once background confounders were controlled. In our study we assessed exposure to the World Trade Center disaster (WTCD) and other negative life events, demographic factors, social support, self-esteem, and panic attack onset in predicting health outcome among 1681 New York City residents 2 years after the attack. Initial bivariate results indicated that a PPA was related to a number of adverse outcomes 2 years after the WTCD, including posttraumatic stress disorder, depression, poor physical health, anxiety, binge drinking, and mental health treatment seeking. However, when multivariate (MV) models were estimated adjusting for potential confounders, most of these associations were either non-significant or substantially reduced. Contrary to previous predictions, these MV models revealed that recent negative life events and current self-esteem at follow-up were the best predictors of health outcomes, not PPA. Although post-trauma interventions may target individuals who experienced PPA after traumatic exposures, reducing the long-term health consequences following such exposures based on PPA alone may be problematic. Modifications of psychopathology constructs based on the reported correlation between PPA and post-trauma outcomes may be premature.

This study investigated an anxiety-prone cognitive style (measured by the Anxious Thoughts and Tendencies Questionnaire, AT&T) as a predictor of the acute response to increasing alprazolam plasma levels in panic disorder. Panic disorder patients (n=26) were treated with escalating doses of alprazolam for 4 weeks, then a fixed dose of 1 mg four times a day for 4 weeks. At 0, 1, 2, 3, 4, 6, and 8 weeks, trough alprazolam plasma levels; clinical, self-report, and performance measures; and vital signs were assessed. Panic attack data were from daily diaries. The repeated response measures were analyzed in relation to alprazolam plasma levels using SAS GENMOD, with patients classified as high or low on the baseline AT&T. Panic attacks, anticipatory anxiety, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, and clinicians' global ratings improved with increasing alprazolam plasma levels. Hopkins Symptom Checklist-90 Anger-Hostility; Profile of Mood States Vigor, Confusion, and Friendliness; and speed and accuracy of performance worsened. Patients with high AT&T scores were worse throughout the study on situational panics, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, the Hamilton Rating Scale for Depression, and Clinical Global Improvement; most Hopkins Symptom Checklist-90 clusters; Profile of Mood States Anxiety, Depression, and Confusion; and Continuous Performance Task omissions. We conclude that in panic disorder: (1) alprazolam has a broad spectrum of clinical activity related to plasma levels in individual patients; (2) sedation, disinhibition, and performance deficits may persist for at least a month after dose escalation ends; (3) marked anxiety-prone cognitions predict more symptoms throughout treatment, but do not modify the response to alprazolam and therefore should not influence the choice of alprazolam as treatment.

An hypothesis is proposed that there exists a subgroup of African-American hypertensive patients whose hypertension could have been prevented by the early detection and treatment of easily recognizable symptoms that signal the initiation of the pathophysiologic processes that lead to essential hypertension. A pilot study of 31 patients with elevated blood pressure revealed that 41.9 percent had isolated sleep paralysis, 35.5 percent had panic attacks, and 9.7 percent had panic disorder. These proposed hyperadrenergic phenomena may be related to the development of hypertension in certain individuals. PMID:3351970

Comorbidity and Suicidality in Patients Diagnosed with Panic Disorder/Agoraphobia and Major Depression.

2017-06-01

Comorbidity of anxiety and depression (both current and lifetime) is associated with greater chronicity and an increased risk of suicidality. We wished to ascertain which symptom clusters had the strongest association with suicidality. Our aims were (1) to examine the presence of current comorbidity and suicidality in patients diagnosed with panic disorder/agoraphobia (PD/A) and major depression (MD), and their relationship with duration of psychiatric treatment and frequency of hospital admission; and (2) to examine which coexisting symptoms were most strongly predictive of suicidality in sub-groups and the overall group. The study sample comprised 100 patients with PD/A and MD. The following assessment instruments were applied: the Panic and Agoraphobia Scale, the Beck Anxiety Inventory, the Beck Depression Inventory-II, the Beck Scale for Suicide Ideation, the Obsessive-Compulsive Inventory-Revised, the Liebowitz Social Anxiety Scale and the Whiteley Index of Hypochondriasis. High rates of current comorbidity were seen in both groups. Patients with MD had significantly higher suicidality scores, but were also older, with a longer duration of psychiatric treatment and more frequent hospitalizations. In the overall group, psychiatric comorbidity was correlated with duration of psychiatric treatment and frequency of hospitalizations (with the exception of hypochondriasis which was not correlated with frequency of hospitalization). In both sub-groups and the overall group, suicidality was correlated with scores for all examined comorbidity (with the exception of hypochondriasis in the PD/A group): however, after multiple regression only obsessive-compulsive symptomatology predicted suicidality in all sub-groups and the overall group, as well as depression in the overall group. Depression supposed as dependent variable and obsessive-compulsive symptomatology as a mediator explained around 37% of the variance in suicidal ideation. Patients with PD/A or MD show high rates of current comorbidity. The effect of depression on suicidality was significant, but a non-trivial impact was also mediated by obsessive-compulsive symptomatology.

This study reports the prevalence and comorbidity of depression in two large samples of black and white young adult women. Clinical interviews of participants in a follow-up study of the National Heart, Lung, and Blood Institute Growth and Health Study (NGHS-Wave II; N=378) were contrasted with a subsample of the National Comorbidity Survey (NCS; N=3749) to examine the rates and comorbidity of lifetime major depressive disorder in black and white women using methodology described by . The sequencing of disorders was also examined to determine which disorder was primary. Comorbidity and sequencing were examined for alcohol and drug use disorder, panic disorder, specific phobia, social phobia, and post-traumatic stress disorder. Prevalence estimates for depression, alcohol use disorder, and drug use disorder were higher for white women than for black women in both NGHS-Wave II and NCS. Over half of depressed participants in both samples had at least one comorbid disorder and depression was associated with an increased probability of all the investigated disorders. Only one ethnic difference was found in comorbidity, indicating that black women were more likely to have comorbid panic disorder than white women were. Depression was primary to alcohol and substance use disorders, whereas it was secondary to specific phobia and PTSD. High rates of comorbidity were found for both black and white women, though few ethnic differences in comorbidity were found. Preventive and treatment interventions are needed to address multiple disorders in young adult women.

Missense mutation of the cholecystokinin B receptor gene: Lack of association with panic disorder

Cholecystokinin tetrapeptide (CCK{sub 4}) is known to induce panic attacks in patients with panic disorder at a lower dose than in normal controls. Therefore, the cholecystokinin B (CCK{sub B}) receptor gene is a candidate gene for panic disorder. We searched for mutations in the CCK{sub B} gene in 22 probands of panic disorder pedigrees, using single-strand conformation polymorphism (SSCP) analysis. Two polymorphisms were detected. A polymorphism in an intron (2491 C{yields}A) between exons 4 and 5 was observed in 10 of 22 probands. A missense mutation in the extracellular loop of exon 2 (1550 G{yields}A, Val{sup 125}{yields}Ile) was found inmore » only one proband. This mutation was also examined in additional 34 unrelated patients with panic disorder and 112 controls. The prevalence rate of this mutation was 8.8% in patients with panic disorder (3/34) and 4.4% in controls (5/112). The mutation did not segregate with panic disorder in two families where this could be tested. These results suggest no pathophysiological significance of this mutation in panic disorder. 21 refs., 4 figs., 1 tab.« less

A good time to panic? Premorbid and postmorbid panic disorder in heart failure affects cardiac and psychiatric cause admissions.

The authors sought to identify characteristics associated with premorbid and postmorbid panic disorder onset in relation to heart failure (HF) onset, and examine the effect on unplanned hospital admissions. In a two-stage screening process, 404 HF patients admitted to three hospitals in South Australia were referred for structured psychiatric interview when any of the following four criteria were met: (a) Patient Health Questionnaire≥10; (b) Generalized Anxiety Disorder Questionnaire≥7); (c) positive response to one-item panic attack screener; (d) or evidence of suicidality. A total of 73 referred HF patients (age 60.6±13.4, 47.9% female) were classified into three groups: premorbid panic disorder (27.4%), postmorbid panic disorder (24.7%), and no panic disorder (47.9%). Postmorbid panic disorder was associated with more psychiatric admissions and longer hospital stay in the 6 months prior to the index psychiatric assessment, and also in the 6 months after the index psychiatric assessment (all p<.05 unadjusted). In sensitivity analysis, years since panic disorder onset were associated with longer cardiac length of stay (β=.34, p=.03). Panic disorder onset in relation to HF diagnosis was associated with discrete patterns of hospital admissions for cardiac and psychiatric causes. © The Royal Australian and New Zealand College of Psychiatrists 2015.

This clinical case report shows how important it is for a psychiatrist to have a knowledge of the cultural and religious context of the patient, in order to understand fully his or her complaints. Culture and religion, in fact, are not neutral, but convey symbols, meanings, and myths that should be properly explored to shed light on the patient's inner world. Patient D was a 19-year-old Muslim Italo-Tunisian girl, who consulted a psychiatrist for anxiety and panic attacks, and reported being possessed by djinns (ie, "evil creatures", as described in the Qur'an). A culturally informed interview was carried out, together with administration of psychometric scales, including the Symptom Checklist-90 Revised and Psychological Measure of Islamic Religiousness. Based on her scores and the results of this multidimensional assessment, patient D was treated with transcultural psychotherapy and fluoxetine. After a year of follow-up, she reported no further episodes of panic disorder. For proper assessment and treatment, a combined anthropological, sociological, and psychopathological approach was necessary.

Diversity of effective treatments of panic attacks: what do they have in common?

PubMed

Roth, Walton T

2010-01-01

By comparing efficacious psychological therapies of different kinds, inferences about common effective treatment mechanisms can be made. We selected six therapies for review on the basis of the diversity of their theoretical rationales and evidence for superior efficacy: psychoanalytic psychotherapy, hypercapnic breathing training, hypocapnic breathing training, reprocessing with and without eye-movement desensitization, muscle relaxation, and cognitive behavior therapy. The likely common element of all these therapies is that they reduce the immediate expectancy of a panic attack, disrupting the vicious circle of fearing fear. Modifying expectation is usually regarded as a placebo mechanism in psychotherapy, but may be a specific treatment mechanism for panic. The fact that this is seldom the rationale communicated to the patient creates a moral dilemma: Is it ethical for therapists to mislead patients to help them? Pragmatic justification of a successful practice is a way out of this dilemma. Therapies should be evaluated that deal with expectations directly by promoting positive thinking or by fostering non-expectancy.

Confusion between panic and asthma symptoms can result in serious self-management errors. A cognitive behavior psychophysiological therapy (CBPT) intervention was culturally adapted for Latinos consisting of CBT for panic disorder (PD), asthma education, differentiation between panic and asthma symptoms, and heart rate variability biofeedback. An RCT compared CBPT to music and relaxation therapy (MRT), which included listening to relaxing music and paced breathing at resting respiration rates. Fifty-three Latino (primarily Puerto Rican) adults with asthma and PD were randomly assigned to CBPT or MRT for 8 weekly sessions. Both groups showed improvements in PD severity, asthma control, and several other anxiety and asthma outcome measures from baseline to post-treatment and 3-month follow-up. CBPT showed an advantage over MRT for improvement in adherence to inhaled corticosteroids. Improvements in PD severity were mediated by anxiety sensitivity in CBPT and by depression in MRT, although earlier levels of these mediators did not predict subsequent improvements. Attrition was high (40%) in both groups, albeit comparable to CBT studies targeting anxiety in Latinos. Additional strategies are needed to improve retention in this high-risk population. Both CBPT and MRT may be efficacious interventions for comorbid asthma-PD, and CBPT may offer additional benefits for improving medication adherence. PMID:27668723

2011-01-01

The current study examined sex differences in psychological (i.e., self-reported anxiety, panic symptoms, and avoidance) and physiological (i.e., heart rate and skin conductance level) response to, and recovery from, a laboratory biological challenge. Participants were a community-recruited sample of 128 adults (63.3% women; Mage = 23.2 years, SD = 8.9) who underwent a 4-minute 10% CO2-enriched air biological challenge. As predicted, women reported more severe physical panic symptoms and avoidance (i.e., less willingness to participate in another challenge) and demonstrated increased heart rate as compared to men above and beyond the variance accounted for by other theoretically-relevant variables (recent panic attack history, neuroticism, and anxiety sensitivity). Additionally, women demonstrated a faster rate of recovery with respect to heart rate compared to men. These results are in line with literature documenting sex-specific differences in panic psychopathology, and results are discussed in the context of possible mechanisms underlying sex differences in panic vulnerability.

This review covers the literature since the publication of DSM-IV on the diagnostic criteria for panic attacks (PAs) and panic disorder (PD). Specific recommendations are made based on the evidence available. In particular, slight changes are proposed for the wording of the diagnostic criteria for PAs to ease the differentiation between panic and surrounding anxiety; simplification and clarification of the operationalization of types of PAs (expected vs. unexpected) is proposed; and consideration is given to the value of PAs as a specifier for all DSM diagnoses and to the cultural validity of certain symptom profiles. In addition, slight changes are proposed for the wording of the diagnostic criteria to increase clarity and parsimony of the criteria. Finally, based on the available evidence, no changes are proposed with regard to the developmental expression of PAs or PD. This review presents a number of options and preliminary recommendations to be considered for DSM-V.

Cognitive models of panic disorder (PD) with or without agoraphobia have stressed the role of catastrophic beliefs of bodily symptoms as a central mediating variable of the efficacy of cognitive behavioral therapy (CBT). Perceived ability to cope with or control panic attacks, panic self-efficacy, has also been proposed to play a key role in therapeutic change; however, this cognitive factor has received much less attention in research. The aim of the present review is to evaluate panic self-efficacy as a mediator of therapeutic outcome in CBT for PD using descriptive and meta-analytic procedures. We performed systematic literature searches, and included and evaluated 33 studies according to four criteria for establishing mediation. Twenty-eight studies, including nine randomized waitlist-controlled studies, showed strong support for CBT improving panic self-efficacy (criterion 1); ten showed an association between change in panic self-efficacy and change in outcome during therapy (criterion 2); three tested, and one established formal statistical mediation of panic self-efficacy (criterion 3); while four tested and three found change in panic self-efficacy occurring before the reduction of panic severity (criterion 4). Although none of the studies fulfilled all of the four criteria, results provide some support for panic self-efficacy as a mediator of outcome in CBT for PD, generally on par with catastrophic beliefs in the reviewed studies.

New daily persistent headache (NDPH) is a primary chronic daily headache that is generally considered to be difficult to treat. Migraine has been linked to comorbid psychiatric conditions, mainly mood and anxiety disorders, but NDPH has never been linked to psychiatric conditions, and never studied extensively for such an association. We report nine cases (six women and three men) of patients diagnosed with NDPH and panic disorder who were treated for both conditions. Six of them (66%) had good or excellent responses. The spectrum of anxiety disorders, particularly panic disorder, should be considered in NDPH patients. Simultaneous treatment of both disorders may lead to good outcomes.

Respiratory manifestations of panic disorder: causes, consequences and therapeutic implications.

Multiple respiratory abnormalities can be found in anxiety disorders, especially in panic disorder (PD). Individuals with PD experience unexpected panic attacks, characterized by anxiety and fear, resulting in a number of autonomic and respiratory symptoms. Respiratory stimulation is a common event during panic attacks. The respiratory abnormality most often reported in PD patients is increased CO2 sensitivity, which has given rise to the hypothesis of fundamental abnormalities in the physiological mechanisms that control breathing in PD. There is evidence that PD patients with dominant respiratory symptoms are more sensitive to respiratory tests than are those who do not manifest such symptoms, and that the former group constitutes a distinct subtype. Patients with PD tend to hyperventilate and to panic in response to respiratory stimulants such as CO2, triggering the activation of a hypersensitive fear network. Although respiratory physiology seems to remain normal in these subjects, recent evidence supports the idea that they present subclinical abnormalities in respiration and in other functions related to body homeostasis. The fear network, composed of the hippocampus, the medial prefrontal cortex, the amygdala and its brain stem projections, might be oversensitive in PD patients. This theory might explain why medication and cognitive-behavioral therapy are both clearly effective. Our aim was to review the relationship between respiration and PD, addressing the respiratory subtype of PD and the hyperventilation syndrome, with a focus on respiratory challenge tests, as well as on the current mechanistic concepts and the pharmacological implications of this relationship.

This study investigated whether brief training in cognitive therapy for panic disorder (Clark et al., 1994) can improve the outcomes that primary care therapists obtain with their patients. Seven primary care therapists treated 36 patients meeting DSM-IV (APA, 1994) criteria for panic disorder with or without agoraphobia in general practice surgeries. Outcomes for the cohort of patients whom the therapists treated with their usual methods (treatment-as-usual) before the training (N = 12) were compared with those obtained with similar patients treated by the same therapists after brief training and ongoing supervision in cognitive therapy (CT) for panic disorder (N = 24). Treatment-as-usual led to significant improvements in panic severity, general anxiety, and depression. However, only a small proportion (17% of the intent-to-treat sample) became panic free and there was no improvement in agoraphobic avoidance. Patients treated with CT achieved significantly better outcomes on all measures of panic attacks, including panic-free rate (54%, intent-to-treat), and showed significantly greater improvements in agoraphobic avoidance and patient-rated general anxiety. In conclusion, cognitive therapy for panic disorder can be successfully disseminated in primary care with a brief therapist training and supervision programme that leads to significant improvements in patient outcomes.

The aim of this study was to ascertain predictors of comorbid personality disorders in patients with panic disorder with agoraphobia (PDAG). Sixty consecutive outpatients with PDAG were administered the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) for the purpose of diagnosing personality disorders. Logistic regressions were used to identify predictors of any comorbid personality disorder, any DSM-IV cluster A, cluster B, and cluster C personality disorder. Independent variables in these regressions were gender, age, duration of panic disorder (PD), severity of PDAG, and scores on self-report instruments that assess the patient's perception of their parents, childhood separation anxiety, and traumatic experiences. High levels of parental protection on the Parental Bonding Instrument (PBI), indicating a perception of the parents as overprotective and controlling, emerged as the only statistically significant predictor of any comorbid personality disorder. This finding was attributed to the association between parental overprotection and cluster B personality disorders, particularly borderline personality disorder. The duration of PD was a significant predictor of any cluster B and any cluster C personality disorder, suggesting that some of the cluster B and cluster C personality disorders may be a consequence of the long-lasting PDAG. Any cluster B personality disorder was also associated with younger age. In conclusion, despite a generally nonspecific nature of the relationship between parental overprotection in childhood and adult psychopathology, the findings of this study suggest some specificity for the association between parental overprotection in childhood and personality disturbance in PDAG patients, particularly cluster B personality disorders.

Evaluation of JNJ-54717793 a Novel Brain Penetrant Selective Orexin 1 Receptor Antagonist in Two Rat Models of Panic Attack Provocation.

Orexin neurons originating in the perifornical and lateral hypothalamic area are highly reactive to anxiogenic stimuli and have strong projections to anxiety and panic-associated circuitry. Recent studies support a role for the orexin system and in particular the orexin 1 receptor (OX1R) in coordinating an integrative stress response. However, no selective OX1R antagonist has been systematically tested in two preclinical models of using panicogenic stimuli that induce panic attack in the majority of people with panic disorder, namely an acute hypercapnia-panic provocation model and a model involving chronic inhibition of GABA synthesis in the perifornical hypothalamic area followed by intravenous sodium lactate infusion. Here we report on a novel brain penetrant, selective and high affinity OX1R antagonist JNJ-54717793 (1S,2R,4R)-7-([(3-fluoro-2-pyrimidin-2-ylphenyl)carbonyl]- N -[5-(trifluoromethyl)pyrazin-2-yl]-7-azabicyclo[2.2.1]heptan-2-amine). JNJ-54717793 is a high affinity/potent OX1R antagonist and has an excellent selectivity profile including 50 fold versus the OX2R. Ex vivo receptor binding studies demonstrated that after oral administration JNJ-54717793 crossed the blood brain barrier and occupied OX1Rs in the rat brain. While JNJ-54717793 had minimal effect on spontaneous sleep in rats and in wild-type mice, its administration in OX2R knockout mice, selectively promoted rapid eye movement sleep, demonstrating target engagement and specific OX1R blockade. JNJ-54717793 attenuated CO 2 and sodium lactate induced panic-like behaviors and cardiovascular responses without altering baseline locomotor or autonomic activity. These data confirm that selective OX1R antagonism may represent a novel approach of treating anxiety disorders, with no apparent sedative effects.

Cognitive behavioural therapy (CBT) and pharmacological treatment with selective serotonin or serotonin-noradrenalin reuptake inhibitors (SSRI/SSNRI) are regarded as efficacious treatments for panic disorder with agoraphobia (PD/AG). However, little is known about treatment-specific effects on symptoms and neurofunctional correlates. We used a comparative design with PD/AG patients receiving either two types of CBT (therapist-guided (n=29) or non-guided exposure (n=22)) or pharmacological treatment (SSRI/SSNRI; n=28) as well as a wait-list control group (WL; n=15) to investigate differential treatment effects in general aspects of fear and depression (Hamilton Anxiety Rating Scale HAM-A and Beck Depression Inventory BDI), disorder-specific symptoms (Mobility Inventory MI, Panic and Agoraphobia Scale subscale panic attacks PAS-panic, Anxiety Sensitivity Index ASI, rating of agoraphobic stimuli) and neurofunctional substrates during symptom provocation (Westphal-Paradigm) using functional magnetic resonance imaging (fMRI). Comparisons of neural activation patterns also included healthy controls (n=29). Both treatments led to a significantly greater reduction in panic attacks, depression and general anxiety than the WL group. The CBT groups, in particular, the therapist-guided arm, had a significantly greater decrease in avoidance, fear of phobic situations and anxiety symptoms and reduction in bilateral amygdala activation while the processing of agoraphobia-related pictures compared to the SSRI/SSNRI and WL groups. This study demonstrates that therapist-guided CBT leads to a more pronounced short-term impact on agoraphobic psychopathology and supports the assumption of the amygdala as a central structure in a complex fear processing system as well as the amygdala's involvement in the fear system's sensitivity to treatment.

Anxiety sensitivity and its importance in psychiatric disorders.

PubMed

Mantar, Atıl; Yemez, Beyazıt; Alkın, Tunç

2011-01-01

Anxiety sensitivity refers to the extent of beliefs that anxiety symptoms or arousal can have harmful consequences. There is growing evidence for anxiety sensitivity as a risk factor for anxiety disorders. Anxiety sensitivity is elevated in panic disorder as well as other anxiety disorders. It is thought to contribute to the maintenance and severity of anxiety symptoms. Studies have shown that anxiety sensitivity more specifically predicts the future occurrence of panic attacks. The Anxiety Sensitivity Index (ASI), which measures the construct of anxiety sensitivity, has three subscales, namely, the ASI-Physical subscale, ASI-Social subscale and ASI-Mental Incapacitation Concerns subscale. The dimension reflecting "fear of physical sensations" of anxiety sensitivity is the most predictive one of panic attacks and panic disorder. Research on the ASI has demonstrated that persons diagnosed with post-traumatic stress disorder, generalized anxiety disorder, obsessive-compulsive disorder, and social anxiety disorder all had ASI scores higher than normal controls. Depression was speculated to hold a positive correlation to high anxiety sensitivity scores. The relationships between anxiety sensitivity, alcohol and substance use disorders are still unknown. There is evidence that anxiety sensitivity is related with "drinking used as a way of coping". Since anxiety sensitivity is a cognitive construct, it should be taken into consideration when evaluating patients with anxiety and psychotherapeutic formulations.

The purpose of this study was to examine patterns of comorbidity of DSM-III-R anxiety disorders and personality disorders (PD). Two-hundred subjects were independently interviewed with the Structured Clinical Interview for DSM-III-R (SCID) and the Personality Disorder Examination (PDE) face-to-face by two experienced clinicians. One-hundred and forty-six also completed the Personality Diagnositc Questionnaire-Revised (PDQ-R). Rates of personality disorder among patients with and without anxiety disorders were determined by each of the three instruments. Comorbidity between panic disorder social phobia, obsessive-compulsive disorder and simple phobia and a conservative estimate of individual Axis II disorders was examined. Results indicate that panic disorder, either current or lifetime, is associated with borderline, avoidant, and dependent personality disorders: social phobia is associated with avoidant personality disorder, and obsessive-compulsive disorder is associated with obsessive-compulsive and avoidant personality disorders. Anxiety disorders with personality disorders are characterized by chronicity and lower levels of functioning compared with anxiety disorders without personality disorders.

Background The phenotypic variance observed in panic disorder (PD) appears to be best captured by a respiratory and non-respiratory panic subtype. We compared respiratory and non-respiratory panic subtypes across a series of external validators (temporal stability, psychiatric co-morbidity, treatment response) to determine whether subtypes are best conceptualized as differing: (1) only on their symptom profiles with no other differences between them; (2) on a quantitative (i.e. severity) dimension only; or (3) qualitatively from one another. Method Data from a large epidemiological survey (National Epidemiologic Survey on Alcohol and Related Conditions) and a clinical trial (Cross-National Collaborative Panic Study) were used. All analytic comparisons were examined within a latent class framework. Results High temporal stability of panic subtypes was observed, particularly among females. Respiratory panic was associated with greater odds of lifetime major depression and a range of anxiety disorders as well as increased treatment utilization, but no demographic differences. Treatment outcome data did not suggest that the two PD subtypes were associated with differential response to either imipramine or alprazolam. Conclusions These data suggest that respiratory and non-respiratory panic represent valid subtypes along the PD continuum, with the respiratory variant representing a more severe form of the disorder.

Low serum concentrations of vitamin B6 and iron are related to panic attack and hyperventilation attack.

Patients undergoing a panic attack (PA) or a hyperventilation attack (HVA) are sometimes admitted to emergency departments (EDs). Reduced serotonin level is known as one of the causes of PA and HVA. Serotonin is synthesized from tryptophan. For the synthesis of serotonin, vitamin B6 (Vit B6) and iron play important roles as cofactors. To clarify the pathophysiology of PA and HVA, we investigated the serum levels of vitamins B2, B6, and B12 and iron in patients with PA or HVA attending an ED. We measured each parameter in 21 PA or HVA patients and compared the values with those from 20 volunteers. We found that both Vit B6 and iron levels were significantly lower in the PA/HVA group than in the volunteer group. There was no significant difference in the serum levels of vitamins B2 or B12. These results suggest that low serum concentrations of Vit B6 and iron are involved in PA and HVA. Further studies are needed to clarify the mechanisms involved in such differences.

Hypnotherapeutic olfactory conditioning (HOC): case studies of needle phobia, panic disorder, and combat-induced PTSD.

PubMed

Abramowitz, Eitan G; Lichtenberg, Pesach

2009-04-01

The authors developed a technique, which they call hypnotherapeutic olfactory conditioning (HOC), for exploiting the ability of scents to arouse potent emotional reactions. During hypnosis, the patient learns to associate pleasant scents with a sense of security and self-control. The patient can subsequently use this newfound association to overcome phobias and prevent panic attacks. This may be especially effective for posttraumatic stress disorder (PTSD) with episodes of anxiety, flashbacks, and dissociation triggered by smells. The authors present 3 cases, patients with needle phobia, panic disorder, and combat-induced PTSD who were successfully treated with the HOC technique.

Medically unexplained dyspnoea in the pulmonary setting is often accompanied by considerable levels of anxiety, suggestive of psychopathology, in particular panic disorder (PD). This pilot study investigates the value of the Multidimensional Dyspnea Profile as a tool to facilitate identification of a specific dyspnoea profile suggestive of comorbid PD. The verbal descriptors, feeling depressed, air hunger and concentrating on breathing, significantly differentiated between the two groups of patients with pulmonary disease with and without PD. © 2015 Asian Pacific Society of Respirology.

A Laboratory-Based Test of the Relation between Adolescent Alcohol Use and Panic-Relevant Responding

A burgeoning literature supports a link between alcohol use and panic-spectrum problems (e.g., panic attacks, disorder) among adolescents, but the direction of influence has yet to be properly examined. From a theoretical perspective, panic-spectrum problems may increase risk for problematic drinking via affect regulation efforts (e.g., self-medication), and problematic consumption also may increase or initiate panic-relevant responding (e.g., learning or kindling models). The objective of the current investigation was to examine the role of prior alcohol use in predicting panic-relevant responding, as well as panic symptom history in predicting the desire to consume alcohol, in the context of either a voluntary hyperventilation or a low-arousal task. Participants were community-recruited adolescents aged 12-17 years (n = 92, Mage = 15.42, SD = 1.51; 39.1% girls). Results indicated that prior alcohol use predicted panic-relevant responding among those undergoing the hyperventilation task (but not the low-arousal task), and that this finding was robust to the inclusion of theoretically-relevant covariates (i.e. age, sex, negative affectivity). However, panic symptom history did not predict the desire to consume alcohol as a function of either the hyperventilation or low-arousal condition. This work sheds further light on the nature of the relation between panic-spectrum problems and problematic alcohol use in adolescence. Specifically, the current findings suggest that frequent alcohol use may increase panic vulnerability among adolescents, whereas acute panic symptoms may not elicit the immediate (self-reported) desire to drink.

The current study examined sex differences in psychological (i.e., self-reported anxiety, panic symptoms, and avoidance) and physiological (i.e., heart rate and skin conductance level) response to, and recovery from, a laboratory biological challenge. Participants were a community-recruited sample of 128 adults (63.3% women; M(age)=23.2 years, SD=8.9) who underwent a 4-min 10% CO(2)-enriched air biological challenge. As predicted, women reported more severe physical panic symptoms and avoidance (i.e., less willingness to participate in another challenge) and demonstrated increased heart rate as compared to men above and beyond the variance accounted for by other theoretically relevant variables (recent panic attack history, neuroticism, and anxiety sensitivity). Additionally, women demonstrated a faster rate of recovery with respect to heart rate compared to men. These results are in line with literature documenting sex-specific differences in panic psychopathology, and results are discussed in the context of possible mechanisms underlying sex differences in panic vulnerability.

Phobic fears are common in the general population and among individuals with major depression (MD). We know little about the prevalence, clinical correlates, and structure of phobic fears in Chinese women with MD. We assessed 22 phobic fears in 6017 Han Chinese women with MD. We used exploratory factor analysis to examine the structure of these phobic fears. We examined the relationship between individual phobic fears and the severity of MD, neuroticism, comorbid panic disorder, generalized anxiety disorder and dysthymia using logistic regression models. The frequency of phobic fears ranged from 3.0% (eating in public) to 36.0% (snakes). Phobic fears were significantly associated with more severe MD, high neuroticism, and co-morbid panic disorder, generalized anxiety disorder and dysthymia. Our factor analysis suggested four underlying subgroups of phobic fears which differed in their clinical correlates, severity and patterns of comorbidity. Data were collected retrospectively through interview and recall bias may have affected the results. Phobic fears are correlated with comorbid MD and more severe MD. These phobic fears clearly subdivide into four subgroups that differ meaningfully from each other. Copyright © 2014 Elsevier B.V. All rights reserved.

Context Among patients with lung cancer, dyspnea is associated with psychological distress, fatigue, and poor coping. Respiratory symptoms are also a common trigger for panic attacks in the general population. Minimal research has addressed the prevalence of panic disorder or the association of dyspnea with risk of panic disorder in lung cancer. Objectives We explored the frequency of panic disorder symptoms and the association of dyspnea with risk of panic disorder symptoms among patients with newly diagnosed non-small cell lung cancer (NSCLC). Methods During 2006–2010, consecutive patients presenting for initial consultation at a thoracic oncology clinic completed a survey of current symptoms, including dyspnea and panic disorder symptoms. We evaluated the frequency of panic disorder symptoms. Logistic regression was used to test the association of dyspnea with risk of panic disorder symptoms, adjusting for age, gender, disease stage, performance status, and major depression symptoms. Results Among 624 patients (M age=63.7 [SD=12.1]; 52.6% female), 48.1% reported that breathing was at least somewhat difficult and 11.2% endorsed panic disorder symptoms. Dyspnea was independently associated with higher risk of panic disorder symptoms (OR=2.19, 95% CI=1.11–4.31, P=0.02). Younger age and major depression symptoms also were associated with higher risk (P’s<0.01). Conclusion Almost half of patients with newly diagnosed NSCLC reported dyspnea, and patients with dyspnea were over twice as likely to endorse panic disorder symptoms relative to patients without dyspnea. Results highlight the need to differentiate panic disorder symptoms among patients who report dyspnea, particularly those who are younger or experiencing major depression symptoms. PMID:24766738

Ataques de nervios: culturally bound and distinct from panic attacks?

Keough, Meghan E; Timpano, Kiara R; Schmidt, Norman B

2009-01-01

The Diagnostic and Statistical Manual of Mental Disorders [DSM-IV-TR; American Psychiatric Association [APA], 2000) has emphasized the importance of understanding psychopathology within a cultural framework by including culture-bound syndromes within its appendices. These syndromes are proposed to be bound to certain cultures and distinct from other psychological disorders. Included among the syndromes are ataques de nervios (ADN), which are reported to be bound to the Hispanic culture and closely resemble panic attacks. However, the cultural distinctiveness and phenomenology of ADN has not been adequately investigated. The current study employed an ethnically diverse study sample (N=342) of undergraduates. Participants completed a number of measures that assessed acculturation, syndrome and anxiety risk factors. In contrast to the DSM-IV's conceptualization of ADN, the rate of ADN did not significantly vary across the three main groups (African American, Caucasian, and Hispanic participants) nor did it vary based on acculturation. More consistent with the DSM-IV, the symptom comparisons indicated some differentiation between ADN and panic attacks. The present report provides data indicating that ADNs, as described by the DSM-IV, are not unique to the Hispanic culture and are experienced by non-Hispanic individuals at similar rates to Hispanic-endorsement. The findings are consistent with the DSM-IV assertion that ADNs and PAs are distinct syndromes. (c) 2008 Wiley-Liss, Inc.

Panic Disorder (PD) and agoraphobia (AG) are frequently comorbid with obsessive-compulsive disorder (OCD), but the correlates of these comorbidities in OCD are fairly unknown. The study aims were to: 1) estimate the prevalence of PD with or without AG (PD), AG without panic (AG) and PD and/or AG (PD/AG) in a large clinical sample of OCD patients and 2) compare the characteristics of individuals with and without these comorbid conditions. A cross-sectional study with 1001 patients of the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders using several assessment instruments, including the Dimensional Yale-Brown Obsessive-Compulsive Scale and the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. Bivariate analyses were followed by logistic regression models. The lifetime prevalence of PD was 15.3% (N=153), of AG 4.9% (N=49), and of PD/AG 20.2% (N=202). After logistic regression, hypochondriasis and specific phobia were common correlates of the three study groups. PD comorbidity was also associated with higher levels of anxiety, having children, major depression, bipolar I, generalized anxiety and posttraumatic stress disorders. Other independent correlates of AG were: dysthymia, bipolar II disorder, social phobia, impulsive-compulsive internet use, bulimia nervosa and binge eating disorder. Patients with PD/AG were also more likely to be married and to present high anxiety, separation anxiety disorder, major depression, impulsive-compulsive internet use, generalized anxiety, posttraumatic stress and binge eating disorders. Some distinct correlates were obtained for PD and AG in OCD patients, indicating the need for more specific and tailored treatment strategies for individuals with each of these clinical profiles.

2008-01-01

Background The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a large cohort of WTC rescue, recovery, and cleanup workers. We previously documented extensive pulmonary dysfunction in this cohort related to toxic environmental exposures. Objectives Our objective in this study was to describe mental health outcomes, social function impairment, and psychiatric comorbidity in the WTC worker cohort, as well as perceived symptomatology in workers’ children. Methods Ten to 61 months after the WTC attack, 10,132 WTC workers completed a self-administered mental health questionnaire. Results Of the workers who completd the questionnaire, 11.1% met criteria for probable post-traumatic stress disorder (PTSD), 8.8% met criteria for probable depression, 5.0% met criteria for probable panic disorder, and 62% met criteria for substantial stress reaction. PTSD prevalence was comparable to that seen in returning Afghanistan war veterans and was much higher than in the U.S. general population. Point prevalence declined from 13.5% to 9.7% over the 5 years of observation. Comorbidity was extensive and included extremely high risks for impairment of social function. PTSD was significantly associated with loss of family members and friends, disruption of family, work, and social life, and higher rates of behavioral symptoms in children of workers. Conclusions Working in 9/11 recovery operations is associated with chronic impairment of mental health and social functioning. Psychological distress and psychopathology in WTC workers greatly exceed population norms. Surveillance and treatment programs continue to be needed. PMID:18795171

Assessing the clinical utility of agoraphobia in the context of panic disorder.

PubMed

Schmidt, Norman B; Cromer, Kiara R

2008-01-01

In the DSM-IV, a panic disorder (PD) diagnosis includes specification of agoraphobia, which is primarily an index of situational avoidance due to fear of panic. No other anxiety diagnosis requires specification of level of avoidance. This raises the question as to whether agoraphobia provides unique information beyond the core features of PD (i.e., panic attacks and panic-related worry). The incremental validity of agoraphobia, defined using DSM-IV specifiers versus level of situational avoidance, was examined in relation to the expression and treatment of PD (N=146). Analyses indicate that agoraphobia status adds uniquely to the prediction of PD symptoms, impairment, and response to treatment. However, level of situational avoidance, defined either as a continuous or dichotomous variable, appears to have greater utility compared to the DSM-IV method of classifying agoraphobia. In summary, the agoraphobia specifier seems to have clinical utility but this could be improved by focusing on a dimensional assessment of situational avoidance.

Depression is frequent in panic disorder (PD); yet, little is known about its influence on the neural substrates of PD. Difficulties in fear inhibition during safety signal processing have been reported as a pathophysiological feature of PD that is attenuated by depression. We investigated the impact of comorbid depression in PD with agoraphobia (AG) on the neural correlates of fear conditioning and the potential of machine learning to predict comorbidity status on the individual patient level based on neural characteristics. Fifty-nine PD/AG patients including 26 (44%) with a comorbid depressive disorder (PD/AG+DEP) underwent functional magnetic resonance imaging (fMRI). Comorbidity status was predicted using a random undersampling tree ensemble in a leave-one-out cross-validation framework. PD/AG-DEP patients showed altered neural activation during safety signal processing, while +DEP patients exhibited generally decreased dorsolateral prefrontal and insular activation. Comorbidity status was correctly predicted in 79% of patients (sensitivity: 73%; specificity: 85%) based on brain activation during fear conditioning (corrected for potential confounders: accuracy: 73%; sensitivity: 77%; specificity: 70%). No primary depressed patients were available; only medication-free patients were included. Major depression and dysthymia were collapsed (power considerations). Neurofunctional activation during safety signal processing differed between patients with or without comorbid depression, a finding which may explain heterogeneous results across previous studies. These findings demonstrate the relevance of comorbidity when investigating neurofunctional substrates of anxiety disorders. Predicting individual comorbidity status may translate neurofunctional data into clinically relevant information which might aid in planning individualized treatment. The study was registered with the ISRCTN80046034. Copyright © 2015 Elsevier B.V. All rights reserved.

Background Many patients with panic disorder meet criteria for at least one other diagnosis, most commonly other anxiety or mood disorders. Cognitive-behavioral therapy is the best empirically supported psychotherapy for panic disorder. There is now evidence indicating that cognitive-behavioral therapy for panic disorder yields positive benefits upon comorbid disorders. Objectives The present study aimed to examine the predictors of broad dimensions of psychopathology in panic disorder after cognitive-behavioral therapy. Methods Two hundred patients affected by panic disorder were treated with manualized group cognitive-behavioral therapy. We examined if the baseline personality dimensions of NEO Five Factor Index predicted the subscales of Symptom Checklist-90 Revised at endpoint using multiple regression analysis based on the intention-to-treat principle. Results Conscientiousness score of NEO Five Factor Index at baseline was a predictor of four Symptom Checklist-90 Revised subscales including obsessive-compulsive (β = −0.15, P < 0.01), depression (β = −0.13, P < 0.05), phobic anxiety (β = −0.15, P < 0.05), and Global Severity Index (β = −0.13, P < 0.05). Conclusion Conscientiousness at baseline may predict several dimensions of psychopathology in patients with panic disorder after cognitive-behavioral therapy. For the purpose of improving a wide range of psychiatric symptoms with patients affected by panic disorder, it may be useful to pay more attention to this personal trait at baseline. PMID:29721499

Many myths and legends have had a deep influence on modern language, and on modern medical vernacular. The terms "syrinx" and "panic"are two of the most characteristic examples and their use in neurology and other specialties is well known. This article reviews the history of these words in Greek mythology and their use in modern medicine. It is known by very few that clinical symptoms or conditions, such as syringomyelia and panic attacks, have a mythological origin in their definition and naming.

Novel Psychological Formulation and Treatment of "Tic Attacks" in Tourette Syndrome.

PubMed

Robinson, Sally; Hedderly, Tammy

2016-01-01

One important, but underreported, phenomenon in Tourette syndrome (TS) is the occurrence of "tic attacks." These episodes have been described at conferences as sudden bouts of tics and/or functional tic-like movements, lasting from 15 min to several hours. They have also been described by patients in online TS communities. To date, there are no reports of tic attacks in the literature. The aim of this article is to stimulate discussion and inform clinical practices by describing the clinical presentation of 12 children (mean age 11 years and 3 months; SD = 2 years and 4 months) with TS and tic attacks, with a detailed case report for one case (13-year-old male). These children commonly present acutely to casualty departments and undergo unnecessary medical investigations. Interestingly, all children reported comorbid anxiety, with worries about the tics themselves and an increased internal focus of attention on tics once the attacks had started. In keeping with other children, the index case reported a strong internal focus of attention, with a relationship between physiological sensations/tic urges, worries about having tic attacks, and behavioral responses (e.g., body scanning, situational avoidance, and other responses). In our experience, the attacks reduce with psychological therapy, for example, the index case attended 13 sessions of therapy that included metacognitive and attention training techniques, as well as cognitive-behavioral strategies. Following treatment, an improvement was seen across a range of measures assessing tics, mood, anxiety, and quality of life. Thus, psychological techniques used to treat anxiety disorders are effective at supporting a reduction in tic attacks through modifying attention, worry processes, and negative beliefs. It is hypothesized that an attentional style of threat monitoring, difficulties tolerating internal sensory urges, cognitive misattributions, and maladaptive coping strategies contribute to the onset and maintenance of tic attacks. These cases provide support for the view that tic attacks are triggered and maintained by psychological factors, thereby challenging the view that tic attacks merely reflect extended bouts of tics. As such, we propose that the movements seen in tic attacks may resemble a combination of tics and functional neurological movements, with tic attacks reflecting episodes of panic and anxiety for individuals with TS.

Panic disorder and bipolar disorder: anxiety sensitivity as a potential mediator of panic during manic states.

Panic disorder (PD) occurs at high rates in bipolar disorder and more commonly than in unipolar depression. Reports of PD onset during hypomania and depressive mania (i.e., mixed states) raise questions about whether the affective disturbances of bipolar disorder play a specific role in the exacerbation or onset of PD. Anxiety sensitivity (AS), a risk factor for PD appears greater in bipolar disorder compared to unipolar depression, although the association of specific mood states with AS remains unknown. We examined the association of current mood state (i.e., mixed state, mania or hypomania, bipolar depression, unipolar depression, and euthymia) with Anxiety Sensitivity Index (ASI) scores in 202 individuals with bipolar disorder (n=110) or major depressive disorder (n=92). Current mood state was significantly associated with ASI score (Chi-square=21.2, df=4, p=0.0003). In multiple regression analyses, including covariates for comorbid anxiety disorders, current mania or hypomania was a significant predictor of ASI scores (p<0.04). Current mixed state tended toward a similar association (p<0.10). Conclusions are limited by the study's cross-sectional nature and relatively small sample size. These findings of elevated AS during manic states, independent of comorbid anxiety disorders, provide preliminary support for the hypothesis that manic states contribute to risk for the development or exacerbation of PD, and that AS may contribute to the high prevalence and severity of PD comorbid with bipolar disorder.

Panic disorder and its subtypes: a comprehensive analysis of panic symptom heterogeneity using epidemiological and treatment seeking samples

Background Panic disorder (PD) is a heterogeneous syndrome that can present with a variety of symptom profiles that potentially reflect distinct etiologic pathways. The present study represents the most comprehensive examination of phenotypic variance in PD with and without agoraphobia for the purpose of identifying clinically relevant and etiologically meaningful subtypes. Method Latent class (LC) and factor mixture analysis were used to examine panic symptom data ascertained from three national epidemiologic surveys [Epidemiological Catchment Area (ECA), National Comorbidity Study (NCS), National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), Wave 1], a twin study [Virginia Adult Twin Study of Psychiatric and Substance Use Disorders (VATSPSUD)] and a clinical trial (Cross-National Collaborative Panic Study [CNCPS]). Results Factor mixture models (versus LC) generally provided better fit to panic symptom data and suggested two panic classes for the ECA, VATSPSUD and CNCPS, with one class typified by prominent respiratory symptoms. The NCS yielded two classes, but suggested both qualitative and quantitative differences. The more contemporary NESARC sample supported a two and three class model, with the three class model suggesting two variants of respiratory panic. The NESARC’s three class model continued to provide the best fit when the model was restricted to a more severe form of PD/panic disorder with agoraphobia. Conclusions Results from epidemiologic and clinical samples suggest two panic subtypes, with one subtype characterized by a respiratory component and a second class typified by general somatic symptoms. Results are discussed in light of their relevance to the etiopathogenesis of PD. PMID:21557895

Panic symptoms in transient loss of consciousness: Frequency and diagnostic value in psychogenic nonepileptic seizures, epilepsy and syncope.

Previous studies suggest that ictal panic symptoms are common in patients with psychogenic nonepileptic seizures (PNES). This study investigates the frequency of panic symptoms in PNES and if panic symptoms, just before or during episodes, can help distinguish PNES from the other common causes of transient loss of consciousness (TLOC), syncope and epilepsy. Patients with secure diagnoses of PNES (n=98), epilepsy (n=95) and syncope (n=100) were identified using clinical databases from three United Kingdom hospitals. Patients self-reported the frequency with which they experienced seven symptoms of panic disorder in association with their episodes. A composite panic symptom score was calculated on the basis of the frequency of symptoms. 8.2% of patients with PNES reported "never" experiencing any of the seven panic symptoms in their episodes of TLOC. Patients with PNES reported more frequent panic symptoms in their attacks than those with epilepsy (p<0.001) or syncope (p<0.001), however, patients with PNES were more likely "rarely" or "never" to report five of the seven-ictal panic symptoms than "frequently" or "always" (45-69% versus 13-29%). A receiver operating characteristic analysis demonstrated that the composite panic symptom score distinguished patients with PNES from the other groups (sensitivity 71.1%, specificity 71.2%), but not epilepsy from syncope. Patients with PNES report TLOC associated panic symptoms more commonly than those with epilepsy or syncope. Although panic symptoms are reported infrequently by most patients with PNES, a composite symptom score may contribute to the differentiation between PNES and the other two common causes of TLOC.

Comorbidity of some anxiety disorders and depression were examined in order to compare their statistical closeness. Patients treated in an out-patient care center for psychiatric disorders and/or family medicine were recruited. Persons that have anxiety and depressive symptoms as a consequence of somatic illnesses or consequence of other psychiatric disorders were excluded. Disorders were diagnosed a with diagnostic questionnaire based on Schedule for Assessment in Neuropsychiatry (SCAN), version 2.0, according to ICD-10 criteria. Analyses include selected disorders: generalized anxiety disorder, panic disorder, agoraphobia, specific phobias, social phobia and depression. 104 patients were included. 35 of them (33.7%) had anxiety disorders, 13 persons (12.5%) have depression. Analyses show that in patients with generalized anxiety disorder, depression occurred at least twice as often as in the remaining patients (odds ratio = 7.1), while in patients with agoraphobia the occurrence of panic disorder increased at least by 2.88 times (odds ratio = 11.9). In other disorders the odds ratios was greater than 1, but the differences were not statistically significant. Depression/generalized anxiety disorder and agoraphobia/panic disorder were shown to be statistically closer than other disorders.

Cognitive-behavioral therapy (CBT) is a first-line treatment for panic disorder with agoraphobia (PD/AG). Nevertheless, an understanding of its mechanisms and particularly the role of therapist-guided exposure is lacking. This study was aimed to evaluate whether therapist-guided exposure in situ is associated with more pervasive and long-lasting effects than therapist-prescribed exposure in situ. A multicenter randomized controlled trial, in which 369 PD/AG patients were treated and followed up for 6 months. Patients were randomized to 2 manual-based variants of CBT (T+/T-) or a wait-list control group (WL; n = 68) and were treated twice weekly for 12 sessions. CBT variants were identical in content, structure, and length, except for implementation of exposure in situ: In the T+ variant (n = 163), therapists planned and supervised exposure in situ exercises outside the therapy room; in the T- group (n = 138), therapists planned and discussed patients' in situ exposure exercises but did not accompany them. Primary outcome measures were (a) Hamilton Anxiety Scale, (b) Clinical Global Impression, (c) number of panic attacks, and (d) agoraphobic avoidance (Mobility Inventory). For T+ and T- compared with WL, all outcome measures improved significantly with large effect sizes from baseline to post (range = -0.5 to -2.5) and from post to follow-up (range = -0.02 to -1.0). T+ improved more than T- on the Clinical Global Impression and Mobility Inventory at post and follow-up and had greater reduction in panic attacks during the follow-up period. Reduction in agoraphobic avoidance accelerated after exposure was introduced. A dose-response relation was found for Time × Frequency of Exposure and reduction in agoraphobic avoidance. Therapist-guided exposure is more effective for agoraphobic avoidance, overall functioning, and panic attacks in the follow-up period than is CBT without therapist-guided exposure. Therapist-guided exposure promotes additional therapeutic improvement--possibly mediated by increased physical engagement in feared situations--beyond the effects of a CBT treatment in which exposure is simply instructed.

Background: Comprehensive cognitive behavior therapies have been proved to be more effective than behavioral interventions. However, the efficacy of CBT is not studied in the Indian context and also, the amount of change brought about by CBT is not known. Aims: This study aims to examine the efficacy of cognitive behavioral intervention (CBI) in the treatment of panic disorder. Our specific objectives were to assess the effectiveness of CBI in reducing symptom severity as well as cognitions related to panic and panic-related behaviors. Design: The study adopted a two-group comparison with pre- and postassessments design. Materials and Methods: The sample consisted of 30 patients sequentially allotted to the CBI (n = 15) and behavioral intervention (BI, n = 15) groups. Assessment was done using a semistructured interview schedule, panic disorder severity scale, Texas panic attack record form, Anxiety Sensitivity Index, Agoraphobic cognitions questionnaire, Behavioral avoidance checklist, and Panic appraisal inventory. The CBI group was provided with comprehensive cognitive behavior therapy and the BI group with psycho-education and applied relaxation. Results: CBI was found to be superior to BI in the reduction of panic symptoms, behavioral avoidance, safety behaviors, and cognitions. A large percentage of the CBI group patients met the criteria for clinically significant change with a large magnitude of change. Conclusion: Multicomponent CBI is superior to BI in terms of the amount of change it brings about with respect to panic symptoms, avoidance, safety behaviors, and cognitions. PMID:19823629

The amygdala has been known to play a pivotal role in mediating fear-related responses including panic attacks. Given the functionally distinct role of the amygdalar subregions, morphometric measurements of the amygdala may point to the pathophysiological mechanisms underlying panic disorder. The current study aimed to determine the global and local morphometric alterations of the amygdala related to panic disorder. Volumetric and surface-based morphometric approach to high-resolution three-dimensional T1-weighted images was used to examine the structural variations of the amygdala, with respect to extent and location, in 23 patients with panic disorder and 31 matched healthy individuals. There were no significant differences in bilateral amygdalar volumes between patients with panic disorder and healthy individuals despite a trend-level right amygdalar volume reduction related to panic disorder (right, β = -0.23, p = 0.09, Cohen's d = 0.51; left, β = -0.18, p = 0.19, Cohen's d = 0.45). Amygdalar subregions were localized into three groups including the superficial, centromedial, and laterobasal groups based on the cytoarchitectonically defined probability map. Surface-based morphometric analysis revealed shape alterations in the laterobasal and centromedial groups of the right amygdala in patients with panic disorder (false discovery rate corrected p < 0.05). The current findings suggest that subregion-specific shape alterations in the right amygdala may be involved in the development and maintenance of panic disorder, which may be attributed to the cause or effects of amygdalar hyperactivation.

Exaggerated compensatory response to acute respiratory alkalosis in panic disorder is induced by increased lactic acid production.

In acute respiratory alkalosis, the severity of alkalaemia is ameliorated by a decrease in plasma [HCO(3)(-)] of 0.2 mEq/L for each 1 mmHg decrease in PaCO(2). Although hyperventilation in panic disorder patients is frequently encountered in outpatients, the drop in plasma [HCO(3)(-)] sometimes surpasses the expectation calculated from the above formula. The quantitative relationship between reduced PaCO(2) and plasma [HCO(3)(-)] in acute respiratory alkalosis has not been studied in panic disorder patients. Our objective was to provide reference data for the compensatory metabolic changes in acute respiratory alkalosis in panic disorder patients. In 34 panic disorder patients with hyperventilation attacks, we measured arterial pH, PaCO(2), plasma [HCO(3)(-)] and lactate on arrival at the emergency room. For each decrease of 1 mmHg in PaCO(2), plasma [HCO(3)(-)] decreased by 0.41 mEq/L. During hypocapnia, panic disorder patients exhibited larger increases in serum lactate levels (mean +/- SD; 2.59 +/- 1.50 mmol/L, range; 0.78-7.78 mmol/L) than previously reported in non-panic disorder subjects. Plasma lactate accumulation was correlated with PaCO(2) (P < 0.001). These results suggest that the compensatory metabolic response to acute respiratory alkalosis is exaggerated by increased lactic acid production in panic disorder patients. Here, we call attention to the diagnosis of acid-base derangements by means of plasma [HCO(3)(-)] and lactate concentration in panic disorder patients.

Do symptom interpretations mediate the relationship between panic attack symptoms and agoraphobic avoidance?

PubMed

Berle, David; Starcevic, Vladan; Milicevic, Denise; Hannan, Anthony; Moses, Karen

2010-05-01

There is little consensus as to whether agoraphobic avoidance in panic disorder is characterized by a prominence of particular symptoms and interpretations of those symptoms. We sought to clarify the relationship between symptoms and agoraphobic avoidance and to establish whether catastrophic interpretations of symptoms mediate any such relationships. The Symptom Checklist 90-Revised, Agoraphobic Cognitions Questionnaire and Mobility Inventory were administered to 117 patients with panic disorder who were attending an outpatient anxiety disorders clinic. Medium to large associations were found between most symptoms and agoraphobic avoidance and between particular symptoms and the corresponding symptom interpretation items. Some interpretations of symptoms were found to mediate relationships between symptoms and agoraphobic avoidance. These findings suggest that the catastrophic misinterpretation model of panic disorder can to some extent be invoked to explain the extent of agoraphobic avoidance, but that there may also be other pathways leading from symptoms to agoraphobia.

Data on clinical differences between episodic (eCH) and chronic cluster headache (cCH) and accompanying migraine features are limited. History and clinical features of 209 consecutive cluster headache patients (144 eCH, 65 cCH; male:female ratio 3.4 : 1) were obtained in a tertiary headache centre by face-to-face interviews. Relationship between occurrence of accompanying symptoms, pain intensity, comorbid migraine, and circannual and circadian rhythmicity was analysed. 99.5% of patients reported a minimum of one ipsilateral cranial autonomic symptom (CAS); 80% showed at least three CAS. A seasonal rhythmicity was observed in both eCH and cCH. A comorbid headache disorder occurred in 25%. No significant difference was detected between patients with comorbid migraine and without regarding occurrence of phonophobia, photophobia or nausea during cluster attacks. Patients with comorbid migraine reported allodynia significantly (p = 0.022) more often during cluster attacks than patients without comorbid migraine. Occurrence of CAS and attack frequency, as well as periodic patterns of attacks, are relatively uniform in eCH and cCH. Multiple CAS are not related to pain intensity. Allodynia during cluster attacks is a frequent symptom. The unexpectedly high rate of accompanying migrainous features during cluster attacks cannot be explained by comorbid migraine.

Does help-seeking alter the risk for incident psychopathology in adolescents and young adults with and without fearful spells or panic attacks? Findings from a 10-year prospective-longitudinal community study.

Although fearful spells (FS) and panic attacks (PA) increase the risk for various mental disorders, few studies have examined whether help-seeking in those with FS/PA attenuates the risk for incident psychopathology. A community sample of adolescents and young adults (N=2978, aged 14-24 at baseline) was followed up in up to 3 assessment waves over 10 years. FS, PA, psychopathology, and help-seeking were assessed using the DSM-IV/M-CIDI. Logistic regressions with interaction terms (adjusted for sex and age) were used to test interactions between FS/PA and help-seeking at baseline on predicting incident psychopathology at follow-up. Cases with panic disorder (PD) at baseline were excluded from all analyses. FS/PA at baseline predicted the onset of any disorder, any anxiety disorder, PD, agoraphobia, generalized anxiety disorder, social phobia, and depression at follow-up (Odds Ratios, OR 1.62-5.80). FS/PA and help-seeking at baseline interacted on predicting incident PD (OR=0.09) and depression (OR=0.22) at follow-up in a way that FS/PA only predicted the respective disorders in individuals not seeking help at baseline. In those with FS/PA, a higher number of panic symptoms interacted with help-seeking on predicting incident PD (OR=0.63) in a way that a higher number of panic symptoms only increased the risk for PD in those without help-seeking at baseline. Help-seeking at baseline was not restricted to panic-specific interventions, but included treatment due to other psychological problems as well. Findings suggest that early help-seeking might modify psychopathology trajectories and prevent incident disorders in high-risk individuals with FS/PA. Copyright © 2014 Elsevier B.V.

Orexin neurons originating in the perifornical and lateral hypothalamic area are highly reactive to anxiogenic stimuli and have strong projections to anxiety and panic-associated circuitry. Recent studies support a role for the orexin system and in particular the orexin 1 receptor (OX1R) in coordinating an integrative stress response. However, no selective OX1R antagonist has been systematically tested in two preclinical models of using panicogenic stimuli that induce panic attack in the majority of people with panic disorder, namely an acute hypercapnia-panic provocation model and a model involving chronic inhibition of GABA synthesis in the perifornical hypothalamic area followed by intravenous sodium lactate infusion. Here we report on a novel brain penetrant, selective and high affinity OX1R antagonist JNJ-54717793 (1S,2R,4R)-7-([(3-fluoro-2-pyrimidin-2-ylphenyl)carbonyl]-N-[5-(trifluoromethyl)pyrazin-2-yl]-7-azabicyclo[2.2.1]heptan-2-amine). JNJ-54717793 is a high affinity/potent OX1R antagonist and has an excellent selectivity profile including 50 fold versus the OX2R. Ex vivo receptor binding studies demonstrated that after oral administration JNJ-54717793 crossed the blood brain barrier and occupied OX1Rs in the rat brain. While JNJ-54717793 had minimal effect on spontaneous sleep in rats and in wild-type mice, its administration in OX2R knockout mice, selectively promoted rapid eye movement sleep, demonstrating target engagement and specific OX1R blockade. JNJ-54717793 attenuated CO2 and sodium lactate induced panic-like behaviors and cardiovascular responses without altering baseline locomotor or autonomic activity. These data confirm that selective OX1R antagonism may represent a novel approach of treating anxiety disorders, with no apparent sedative effects. PMID:28649201

The learning perspective of panic disorder distinguishes between acute panic and anxious apprehension as distinct emotional states. Following animal models, these clinical entities reflect different stages of defensive reactivity depending upon the imminence of interoceptive or exteroceptive threat cues. The current study tested this model by investigating the dynamics of defensive reactivity in a large group of patients with panic disorder and agoraphobia (PD/AG). Three hundred forty-five PD/AG patients participated in a standardized behavioral avoidance test (being entrapped in a small, dark chamber for 10 minutes). Defense reactivity was assessed measuring avoidance and escape behavior, self-reports of anxiety and panic symptoms, autonomic arousal (heart rate and skin conductance), and potentiation of the startle reflex before and during exposure of the behavioral avoidance test. Panic disorder and agoraphobia patients differed substantially in their defensive reactivity. While 31.6% of the patients showed strong anxious apprehension during this task (as indexed by increased reports of anxiety, elevated physiological arousal, and startle potentiation), 20.9% of the patients escaped from the test chamber. Active escape was initiated at the peak of the autonomic surge accompanied by an inhibition of the startle response as predicted by the animal model. These physiological responses resembled the pattern observed during the 34 reported panic attacks. We found evidence that defensive reactivity in PD/AG patients is dynamically organized ranging from anxious apprehension to panic with increasing proximity of interoceptive threat. These data support the learning perspective of panic disorder. Copyright © 2012 Society of Biological Psychiatry. Published by Elsevier Inc. All rights reserved.

Although research suggests that (a) childhood adversities and more recent stressful life events/conditions are risk factors for panic pathology and that (b) early life stress increases vulnerability to later psychopathology, it remains unclear whether childhood adversities amplify the association between more recent stressful life events/conditions and panic pathology. Data were derived from a general population sample (Study of Health in Pomerania, SHIP). Lifetime panic pathology was assessed with the Munich Composite International Diagnostic Interview (M-CIDI). Childhood adversities (emotional, physical and sexual abuse; emotional and physical neglect) were assessed with the Childhood Trauma Questionnaire (CTQ). More recent separation/loss events and long-lasting stressful conditions were assessed with the Stralsund Life Event List (SEL). Individuals with lifetime panic pathology (fearful spell, panic attack or panic disorder, N = 286) were compared to controls without any psychopathology (N = 286, matched for sex and age). Conditional logistic regressions revealed that childhood adversities as well as more recent separation/loss events and long-lasting stressful conditions were associated with panic pathology (OR 1.1-2.5). Moreover, more recent separation/loss events - but not long-lasting stressful conditions - interacted statistically with each of the examined childhood adversities except for sexual abuse in predicting panic pathology (OR 1.1-1.3). That is, separation/loss events were associated more strongly with panic pathology among individuals with higher childhood adversities. Data were assessed retrospectively and might be subject to recall biases. Findings suggest that early childhood adversities amplify the risk of developing panic pathology after experiencing separation or loss events. Copyright © 2017. Published by Elsevier B.V.

This international, multicenter, cross-sectional study comprising 1346 adult in- and outpatients with major depressive disorder (MDD) investigated the association between MDD as primary diagnosis and comorbid post-traumatic stress disorder (PTSD). In a cross-sectional data collection process, the presence of comorbid PTSD was determined by the Mini International Neuropsychiatric Interview (MINI) and the patients' socio-demographic, clinical, psychopharmacological, and response information were obtained. Clinical features between MDD with and without concurrent PTSD were compared using descriptive statistics, analyses of covariance (ANCOVA), and binary logistic regression analyses. 1.49% of the MDD patients suffered from comorbid PTSD. Significantly more MDD + comorbid PTSD patients exhibited atypical features, comorbid anxiety disorders (any comorbid anxiety disorder, panic disorder, agoraphobia, and social phobia), comorbid bulimia nervosa, current suicide risk, and augmentation treatment with low-dose antipsychotic drugs. In the binary logistic regression analyses, the presence of atypical features (odds ratio (OR) = 4.49, 95%CI:1.01-20.12; p≤.05), any comorbid anxiety disorder (OR = 3.89, 95%CI:1.60-9.44; p = .003), comorbid panic disorder (OR = 6.45, 95%CI:2.52-16.51; p = .001), comorbid agoraphobia (OR = 6.51, 95%CI:2.54-16.68; p≤.001), comorbid social phobia (OR = 6.16, 95%CI:1.71-22.17; p≤.001), comorbid bulimia nervosa (OR = 10.39, 95%CI:1.21-88.64; p = .03), current suicide risk (OR = 3.58, 95%CI:1.30-9.91; p = .01), and augmentation with low-potency antipsychotics (OR = 6.66, 95%CI:2.50-17.77; p<.001) were associated with concurrent PTSD in predominant MDD. Major findings of this study were (1.) the much lower prevalence rate of comorbid PTSD in predominant MDD compared to the reverse prevalence rates of concurrent MDD in primary PTSD, (2.) the high association to comorbid anxiety disorders, and (3.) the increased suicide risk due to concurrent PTSD.

Psychopharmacology of the anxiety disorders.

Ballenger, J C

Although anxiety is a familiar part of all our lives, pathologic anxiety states that lead to occupational and social dysfunction require medical treatment. Currently, the anxiety disorders are divided into nonphobic and phobic disorders. However, recent studies suggest that the disorders should be divided into three symptom groups: (1) generalized anxiety, (2) episodes with severe panic anxiety (panic attacks) plus generalized anxiety or even phobic avoidance, and (3) phobic anxiety and avoidance (alone, without panic attacks). This grouping is highly predictive of response to antianxiety medications. The generalized anxiety group responds well to psychosocial/psychotherapy treatments and to the antianxiety BZs. Many people with nonpanic, nonphobic (situational or generalized) anxiety only require simple psychotherapy or other nonpharmacologic methods to manage their anxiety. However, if the anxious patient is becoming dysfunctional or symptomatology is severe or persistent enough to warrant the use of medication, BZs are certainly the drugs of choice. Despite persistent public or media opinion that they are over-utilized or over-prescribed, most objective data suggest this is not the case. Most individuals for whom they are prescribed need them, use them in proper doses, and discontinue them when the indication passes. Most of the reported abuse occurs in the approximately 8 to 12 per cent who abuse other drugs, most notably alcohol. As anxiety is usually transient, BZs should be prescribed for limited periods (1 to 4 weeks) and then discontinued. This practice allows the physician to properly monitor the amount utilized and to evaluate need for continued BZs. The principal differences among the available BZs are their elimination half-lives, with some greater than 24 hours and others in the 8 to 12 hour range. Side effects are mostly mild (sedation, clumsiness) and drug-drug interactions are uncommon. Until recently, most patients suffering from disorders with panic attacks with or without phobias were either untreated or treated with long, but largely unsuccessful, treatments. Blockade of panic attacks with TCAs, MAOIs and alprazolam has dramatically improved our ability to treat these disorders, with 60 to 95 per cent of patients reporting marked alleviation of symptoms. Adequate amounts of medication and length of treatment period are the keys to successful treatment. This is a period of much productive interest and research in the anxiety disorders. Continued rapid progress in the understanding of the biologic substrates of these conditions and the development of new treatments promise much in this area of medicine in the near future.

In the context of the integrative model of anxiety and depression, we examined whether the essential problem of hypochondriasis is one of anxiety. When analyzed, data from a large nonclinical sample corresponded to the integrative model's characterization of anxiety as composed of both broad, shared and specific, unique symptom factors. The unique hypochondriasis, obsessive-compulsive, and panic attack symptom factors all had correlational patterns expected of anxiety with the shared, broad factors of negative emotionality and positive emotionality. A confirmatory factor analysis showed a higher-order, bifactor model was the best fit to our data; the shared and the unique hypochondriasis and anxiety symptom factors both contributed substantial variance. This study provides refinements to an empirically based taxonomy and clarifies what hypochondriasis is and, importantly, what it is not. Copyright © 2010. Published by Elsevier Ltd.

Patients with panic disorder with agoraphobia (PDA) or generalized anxiety disorder (GAD) frequently also suffer from insomnia. However, the impact of cognitive-behavioral therapy (CBT) for anxiety disorders on insomnia has been understudied. Furthermore, comorbidity between anxiety disorders is common. Our main objective was to assess the impact of CBT for PDA or GAD on insomnia. In a quasi-experimental design, 86 participants with PDA and GAD received conventional CBT for their primary disorder or combined CBT for both disorders. Overall, CBTs had a significant impact on reducing insomnia symptoms (η = 0.58). However, among people with insomnia at pretest (67%), 33% still had an insomnia diagnosis, and the majority (63%) had clinically significant residual insomnia following treatment. In conclusion, the CBTs had a positive effect on the reduction of insomnia, but a significant proportion of participants still had insomnia problems following treatment. Clinicians should address insomnia during CBT for PDA and GAD.

Panic disorder refers to the frequent and recurring acute attacks of anxiety. Objective: This study describes the routine use of mobiles phones (MPs) and investigates the appearance of possible emotional alterations or symptoms related to their use in patients with panic disorder (PD). Background: We compared patients with PD and agoraphobia being treated at the Panic and Respiration Laboratory of The Institute of Psychiatry, Federal University of Rio de Janeiro, Brazil, to a control group of healthy volunteers. Methods: An MP-use questionnaire was administered to a consecutive sample of 50 patients and 70 controls. Results: People with PD showed significant increases in anxiety, tachycardia, respiratory alterations, trembling, perspiration, panic, fear and depression related to the lack of an MP compared to the control group. Conclusions: Both groups exhibited dependence on and were comforted by having an MP; however, people with PD and agoraphobia showed significantly more emotional alterations as well as intense physical and psychological symptoms when they were apart from or unable to use an MP compared to healthy volunteers.

The present investigation examined the extent to which panic reactivity to bodily sensations is related to distress tolerance (DT) among daily smokers. It was hypothesized that panic reactivity to an initial voluntary hyperventilation (i.e., whether participants met criteria for a DSM-IV panic attack; PA) would predict the relative degree of task persistence on a second hyperventilation trial (DT) above and beyond the variance accounted for by anxiety sensitivity (AS), negative affectivity (NA), cigarette smoking rate, and self-reported discomfort intolerance (DI). Participants were 95 daily smokers (58% women; Mage = 29.0, SD = 12.2) who completed a battery of questionnaires and two voluntary hyperventilation procedures. Results indicated PA status significantly predicted DT, above and beyond the theoretically relevant covariates of AS, NA, cigarettes per day, and DI (p < .05). Such a result is consistent with theoretical models and empirical findings on emotional reactivity that suggest panic responsivity to internal cues may represent a key explanatory construct in terms of level of DT to interoceptive stimuli.

Neurologists and the threat of bioterrorism.

Donaghy, Michael

Neurologists are most likely to become involved in primarily diagnosing those bioterrorist attacks utilising botulinum toxin. Oral ingestion, or possibly inhalation, are likely routes of delivery. The characteristic descending paralysis starts in the extraocular and bulbar muscles, with associated autonomic features. Repetitive nerve stimulation usually shows an incremental muscle response. Treatment is supportive. The differential diagnosis is from naturally occurring paralysing illnesses such as Guillain-Barré syndrome, myasthenic crisis or diphtheria, from paralysing seafood neurotoxins (tetrodotoxin, saxitoxin), snake envenomation, and from chemical warfare poisoning by organophosphates. Primary neurological infections are less feasible for use as bioweapons. There are theoretical possibilities of Venezuelan equine encephalitis transmission by inhalation and secondary zoonotic transmission cycles sustained by horses and mosquitoes. Severe haemorrhagic meningitis regularly occurs in anthrax, usually in the aftermath of severe systemic disease likely to have been transmitted by spore inhalation. Panic and psychologically determined 'me-too' symptomatology are likely to pose the biggest diagnostic and management burden on neurologists handling bioterrorist attack on an institution or a random civilian population. Indeed civilian panic and disablement of institutional operations are likely to be prominent intentions of any bioterrorist attack.

Neuropsychological studies have provided evidence for deficits in psychiatric disorders, such as schizophrenia and mood disorders. However, neuropsychological function in Panic Disorder (PD) or PD with a comorbid diagnosis of Major Depressive Disorder (MDD) has not been comprehensively studied. The present study investigated neuropsychological functioning in patients with PD and PD + MDD by focusing on tasks that assess attention, psychomotor speed, executive function, decision-making, and affective processing. Twenty-two unmedicated patients with PD, eleven of whom had a secondary diagnosis of MDD, were compared to twenty-two healthy controls, matched for gender, age, and intelligence on tasks of attention, memory, psychomotor speed, executive function, decision-making, and affective processing from the Cambridge Neuropsychological Test Automated Battery (CANTAB), Cambridge Gamble Task, and Affective Go/No-go Task. Relative to matched healthy controls, patients with PD + MDD displayed an attentional bias toward negatively-valenced verbal stimuli (Affective Go/No-go Task) and longer decision-making latencies (Cambridge Gamble Task). Furthermore, the PD + MDD group committed more errors on a task of memory and visual discrimination compared to their controls. In contrast, no group differences were found for PD patients relative to matched control subjects. The sample size was limited, however, all patients were drug-free at the time of testing. The PD + MDD patients demonstrated deficits on a task involving visual discrimination and working memory, and an attentional bias towards negatively-valenced stimuli. In addition, patients with comorbid depression provided qualitatively different responses in the areas of affective and decision-making processes.

Background Bipolar affective disorder has a high rate of comorbidity with a multitude of psychiatric disorders and medical conditions. Among all the potential comorbidities, co-existing anxiety disorders stand out due to their high prevalence. Aims To determine the lifetime prevalence of comorbid anxiety disorders in bipolar affective disorder under the care of psychiatric services through systematic review and meta-analysis. Method Random effects meta-analyses were used to calculate the lifetime prevalence of comorbid generalised anxiety disorder, panic disorder, social anxiety disorder, specific phobia, agoraphobia, obsessive compulsive disorder and posttraumatic stress disorder in bipolar affective disorder. Results 52 studies were included in the meta-analysis. The rate of lifetime comorbidity was as follows: panic disorder 16.8% (95% CI 13.7–20.1), generalised anxiety disorder 14.4% (95% CI 10.8–18.3), social anxiety disorder13.3% (95% CI 10.1–16.9), post-traumatic stress disorder 10.8% (95% CI 7.3–14.9), specific phobia 10.8% (95% CI 8.2–13.7), obsessive compulsive disorder 10.7% (95% CI 8.7–13.0) and agoraphobia 7.8% (95% CI 5.2–11.0). The lifetime prevalence of any anxiety disorders in bipolar disorder was 42.7%. Conclusions Our results suggest a high rate of lifetime concurrent anxiety disorders in bipolar disorder. The diagnostic issues at the interface are particularly difficult because of the substantial symptom overlap. The treatment of co-existing conditions has clinically remained challenging.

Panic disorder with/without agoraphobia (PD/PDA) is a prevalent anxiety disorder, associated with impairment in quality of life and functionality, as well as increased healthcare utilization. Extant research shows a relationship between stressful life events (SLEs) and the onset of panic attacks in adults who ultimately develop PD/PDA. However, limited attention has been paid to how SLEs might affect the severity of panic symptoms in individuals with PD/PDA. In this study, we examined the relationship between SLEs and panic symptom severity in adults with PD/PDA. Four hundred-eighteen adults with PD/PDA from the Harvard/Brown Anxiety Research Program (HARP), a long-term prospective longitudinal observational multicenter study of adults with a current or past history of anxiety disorders were included in this study. We examined occurrence of SLEs and their impact on panic symptom severity 12-weeks pre- and post-SLE. A time-slope effect showed that participants had worsened panic symptoms over the course of the 12-weeks after family/friends/household and work SLEs. That is, their symptoms worsened progressively after the event, rather than immediately thereafter (i.e., significant symptom change within the same week of the event). The sample may not be representative of the general population. These findings provide new insights into how SLEs affect panic symptoms in adults with PD/PDA in that household-related SLEs, such as serious family arguments, and work-related SLEs, such as being fired, put some adults at risk for worsened panic symptoms within 12-weeks of the event.

Corticotropin releasing factor (CRF) is implicated in a variety of stress-related disorders such as depression and anxiety, and blocking CRF receptors is a putative strategy for treating such disorders. Using a well-studied animal model of panic, we tested the efficacy of JNJ19567470/CRA5626, a selective, non-peptidergic CRF type 1 receptor (CRF1) antagonist (3, 10 and 40 mg/kg intraperitoneal injection), in preventing the sodium lactate (NaLac)-induced panic-like behavioural and cardiovascular responses. Adult male rats with chronic reduction of GABA levels (by inhibition of GABA synthesis with l-allyglycine, a glutamic acid decarboxylase inhibitor) in the dorsomedial/perifornical hypothalamus are highly anxious and exhibit physiological and behavioural responses to intravenous NaLac infusions similar to patients with panic disorder. These 'panic-prone' rats pre-treated with vehicle injections displayed NaLac-induced increases in autonomic responses (i.e. tachycardia and hypertensive responses), anxiety-like behaviour in the social interaction test, and flight-like increases in locomotor activity. However, systemically injecting such panic-prone rats with the highest dose of CRF1 receptor antagonist prior to NaLac infusions blocked all NaLac-induced behaviour and cardiovascular responses. These data suggest that selective CRF1 receptor antagonists could be a novel target for developing anti-panic drugs that are as effective as benzodiazepines in acute treatment of a panic attack without the deleterious side-effects (e.g. sedation and cognitive impairment) associated with benzodiazepines.

The indirect effect of panic disorder on smoking cognitions via difficulties in emotion regulation.

Panic disorder (PD) and cigarette smoking are highly comorbid and associated with worse panic and smoking outcomes. Smoking may become an overlearned automatized response to relieve panic-like withdrawal distress, leading to corresponding smoking cognitions, which contribute to its reinforcing properties and difficultly abstaining. Difficulties in emotion regulation (ER) may underlie this relation such that in the absence of adaptive emotion regulatory strategies, smokers with PD may more readily rely upon smoking to manage affective distress. In the current study, the indirect relation between PD status and smoking cognitions through ER difficulties was examined among daily smokers (N=74). We found evidence for an indirect relation between PD status and negative affect, addictive and habitual smoking motives, and anticipating smoking will result in negative reinforcement and personal harm, through self-reported difficulties with ER. Our findings are aligned with theoretical models on anxiety and smoking, and suggest that reports of greater smoking cognitions may be due to ER difficulties. Copyright © 2017.

Background Panic disorder (PD) is highly comorbid with major depressive disorder (MDD) with potential impact on patient-reported outcomes of quality of life (QOL), functioning, and depressive symptom severity Methods Using data from the sequenced treatment alternatives to relieve depression (STAR*D) trial, we compared entry and post-SSRI-treatment QOL, functioning, and depressive symptom severity scores in MDD patients with comorbid PD (MDD+PD) to MDD patients without PD (MDDnoPD). We also compared pre- and posttreatment proportions of patients with severe impairments in quality of life and functioning. Results MDD+PD patients experienced significantly lower QOL and functioning and more severe depressive symptoms than MDDnoPD patients at entry. Following treatment with citalopram, both groups showed significant improvements, however, nearly 30–60% of patients still suffered from severe quality of life and functioning impairments. MDD+PD patients exited with lower QOL and functioning than MDDnoPD patients, a difference that became statistically insignificant after adjusting for baseline measures of depressive symptom severity, functioning, and QOL, comorbid anxiety disorders (PTSD, GAD, social, and specific phobias), age, and college education. Conclusions Functional outcomes using QOL and functioning measures should be utilized in treating and researching MDD so that shortfalls in traditional treatment can be identified and additional interventions can be designed to address severe baseline QOL and functioning deficits in MDD comorbid with PD.

Concurrent panic disorder with agoraphobia (PDA) and generalized anxiety disorder (GAD) are the most common diagnostic occurrences among anxiety disorders. This particular comorbidity is associated with significant impairments in quality of life (QOL). The current study sought to investigate the efficacy of a combined cognitive-behavioral psychotherapy that addressed both conditions compared with a conventional psychotherapy, which attends solely to the primary disorder. The hypotheses postulated firstly, that both treatment conditions would lead to improvements in participants' QOL and secondly, that the combined therapy would lead to greater QOL ameliorations. Twenty-five participants with comorbid PDA/GAD diagnoses were evaluated with a number of clinical interviews and self-report questionnaires, and were provided with either conventional or combined cognitive-behavioral psychotherapy, which consisted of 14 one-hour weekly sessions. Participants were once again evaluated in the same fashion 2-weeks after the completion of the psychotherapy. The results revealed that both conditions led to significant improvements in participants' QOL, but that the two groups did not significantly differ in terms of the effect on QOL. The results also reveal that the two conditions did not significantly differ in terms of their effect on PDA and GAD symptomatology or psychiatric comorbidity. The results demonstrate that the combined psychotherapy, which addresses both conditions simultaneously, is similar to the conventional psychotherapy employed for the primary disorder in terms of QOL enhancement, symptom severity, and comorbidity reduction.

Anxiety disorders, most notably panic disorders and agoraphobia, are common mental disorders, and there is a high comorbidity with personality disorders. Randomized controlled trails addressing this highly relevant group of patients are missing. The multicenter Anxiety and Personality Disorders (APD) study investigates 200 patients with panic disorder and/or agoraphobia with comorbid personality disorder in a randomized control-group comparison of psychoanalytic therapy (PT) and cognitive behavioral therapy (CBT), including 100 patients in each group. Each patient will be examined over a period of six years, regardless of the duration of the individual treatment. The main issues that are addressed in this study are the comparison of the efficacy of PT and CBT in this special patient population, the comparison of the sustainability of the effects of PT and CBT, the comparison of the long-term cost-benefit-ratios of PT and CBT as well as the investigation of prescriptive patient characteristics for individualized treatment recommendations (differential indication). The APD study compares efficacy, sustainability, and cost-benefit-ratios of CBT and PT for anxiety plus personality disorders in a randomized controlled trail. The study design meets the requirements for an efficacy study for PT, which were recently defined. Current Controlled Trials ISRCTN12449681.

The objective of this work is To investigate the prevalence, comorbidities, impairment, and treatment-seeking of social anxiety disorder in the Chinese military personnel. Military personnel (n=11,527) were surveyed from May to August 2007 using a multistage whole cohort probability sampling method. A Chinese version of the World Health Organization Composite International Diagnostic Interview (CIDI) was used for assessment, and a military-related socio-demographic questionnaire was used to describe the prevalence distribution. A unified survey was performed to investigate 11 different social situations. The short-form health survey was used to assess role impairment. The 12-month and lifetime prevalence rates of social anxiety disorder were 3.34% (95% CI: 3.25-3.42%) and 6.22% (95% CI: 6.11-6.32%), respectively. Social anxiety disorder was associated with increased odds of depression, substance abuse, panic attacks/disorder, and generalized anxiety disorder. Childhood foster, female, stressful life events, younger age, and being divorced/widowed increase the incidence of social anxiety disorder. Treatment-seeking was relatively rare. Social anxiety disorder is a common disorder in military personnel in China, and it is a risk factor for subsequent depressive illness, substance abuse and other mental disorder. Early detection and treatment of social anxiety disorder are important because of the low rate of treatment-seeking. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

In this article, we illustrate how cognitive behavioral therapy (CBT) can be adapted for the treatment of PTSD among traumatized refugees and ethnic minority populations, providing examples from our treatment, culturally adapted CBT, or CA-CBT. CA-CBT has a unique approach to exposure (typical exposure is poorly tolerated in these groups), emphasizes the treatment of somatic sensations (a particularly salient part of the presentation of PTSD in these groups), and addresses comorbid anxiety disorders and anger. To accomplish these treatment goals, CA-CBT emphasizes emotion exposure and emotion regulation techniques such as meditation and aims to promote emotional and psychological flexibility. We describe 12 key aspects of adapting CA-CBT that make it a culturally sensitive treatment of traumatized refugee and ethnic minority populations. We discuss three models that guide our treatment and that can be used to design culturally sensitive treatments: (a) the panic attack-PTSD model to illustrate the many processes that generate PTSD in these populations, highlighting the role of arousal and somatic symptoms; (b) the arousal triad to demonstrate how somatic symptoms are produced and the importance of targeting comorbid anxiety conditions and psychopathological processes; and (c) the multisystem network (MSN) model of emotional state to reveal how some of our therapeutic techniques (e.g., body-focused techniques: bodily stretching paired with self-statements) bring about psychological flexibility and improvement.

To determine the lifetime rates of panic disorder, obsessive-compulsive disorder (OCD), social phobia, and posttraumatic stress disorder (PTSD) among adult Latino patients with major depressive disorder (MDD) and bipolar disorder (BPD), and whether there are dose-response relationships between loading for comorbid anxiety disorders, the probability of having BPD, and attributes of severity of illness. In a public sector clinic for the indigent located in a semiclosed rural community, 187 consecutively presenting affectively ill Latino patients were evaluated by use of the Structured Clinical Interview for DSM-IV. Polarity and the lifetime prevalence of panic disorder, OCD, social phobia, and PTSD were determined. Logistic regression was used to test associations. Trends in positive predictive values (PPVs) and likelihood ratios were assessed to determine whether dose-response relationships existed between loading for comorbid anxiety disorders and the likelihood of having BPD as opposed to MDD, psychosis, suicidal ideation, and suicide attempts. Of 187 subjects, 118 (63.1%) had MDD and 69 (36.9%) had BPD. The odds ratio of a patient with BPD, relative to MDD, of having panic disorder was 4.6 (p< .0001), OCD 7.6 (p< .0001), social phobia 6.0 (p< .0001) and PTSD 5.3 (p< .0001). The PPV of having BPD was 91.3% and of having psychotic features 83.0% if one had all four anxiety disorders. There was a dose-response relationship between loading for comorbid anxiety disorders and the likelihood of having had a suicide attempt (but not suicidal ideation). As previously reported by us for juvenile patients, Latino adults with BPD had a remarkably high risk of having each anxiety disorder relative to patients with MDD. The results indicate that the risk of having BPD, having a psychosis, and making a suicide attempt becomes increasingly great as the number of comorbid anxiety disorders increases. These data, which are consistent with the notion of anxious bipolarity, provide further support for a possible anxious diathesis in bipolar disorder.

To investigate the impact of childhood trauma on the clinical course of panic disorder and possible contributing factors. Longitudinal data of 539 participants with a current panic disorder were collected from the Netherlands Study of Depression and Anxiety (NESDA). Childhood trauma was assessed with a structured interview and clinical course after 2 years with a DSM-IV-based diagnostic interview and the Life Chart Interview. At baseline, 54.5% reported childhood trauma, but this was not predictive of persistence of panic disorder. Emotional neglect and psychological abuse were associated with higher occurrence of anxiety disorders other than panic disorder (social phobia) and with higher chronicity of general anxiety symptoms (anxiety attacks or episodes and avoidance). Baseline clinical features (duration and severity of anxiety and depressive symptoms) and personality traits (neuroticism and extraversion) accounted for roughly 30-60% of the total effect of childhood trauma on chronicity of anxiety symptoms and on occurrence of other anxiety disorders. After two years, childhood trauma is associated with chronicity of anxiety symptoms and occurrence of social phobia, rather than persistence of panic disorder. These relationships are partially accounted for by duration and severity of anxiety and depressive symptoms, and neuroticism and extraversion. © 2017 John Wiley & Sons A/S.

Depersonalization and individualism: the effect of culture on symptom profiles in panic disorder.

PubMed

Sierra-Siegert, Mauricio; David, Anthony S

2007-12-01

It has been proposed that highly individualistic cultures confer vulnerability to depersonalization. To test this idea, we carried out a comprehensive systematic review of published empirical studies on panic disorder, which reported the frequency of depersonalization/derealization during panic attacks. It was predicted that the frequency of depersonalization would be higher in Western cultures and that a significant correlation would be found between the frequency of depersonalization and individualism scores of the participant countries. As predicted, the frequency of depersonalization during panic was significantly lower in nonwestern countries. There was also a significant correlation between frequency of depersonalization and Individualism (rho = 0.68, p < 0.0001), and between fears of losing control (rho = 0.57, p = 0.005) and individualism. These findings are interpreted in light of recent studies suggesting that individualistic cultures are characterized by hypersensitivity to threat and by an external locus of control. Two features may be relevant in the genesis of depersonalization.

Psychogenic Non-Epileptic Seizures (PNES) are events that appear epileptic but are instead thought to have a psychological origin. Increased rates of several psychiatric disorders have been reported in PNES, including anxiety and panic disorders. Some theories suggest panic and/or hyperventilation have aetiological roles in PNES, though these remain unproven. We conducted a systematic review of associations of panic and hyperventilation with PNES using Ovid Medline and PubMed, and a meta-analysis where appropriate. We found eighteen studies reporting rates of panic in PNES and eight studies reporting hyperventilation. The reported rate of panic attacks in PNES ranged from 17% to 83%, with physical symptoms more commonly reported, and affective symptoms less so. 'Dizziness or light-headedness' was found to be more prevalent than 'fear of dying' by random-effects meta-analysis (68% vs. 23%). A proportion meta-analysis found a weighted occurrence of 20% of panic disorder in PNES. A pooled meta-analytic rate of PNES events following voluntary hyperventilation induction was 30%, while the clinically observed rates of peri-ictal hyperventilation in PNES without induction varied from 15 to 46%. Previous studies have reported moderate rates of association of panic in PNES, though the proportions varied considerably across the literature, with physical symptoms more commonly reported than affective. Hyperventilation is an effective inducer of PNES events in a minority, and can be observed occurring in a minority of patients without induction. These results support an important, albeit not essential, role for panic and hyperventilation in the pathogenesis of PNES events. Copyright © 2018 British Epilepsy Association.

We previously demonstrated that carbon dioxide inhalation could induce panic anxiety in a group of rare lesion patients with focal bilateral amygdala damage. To further elucidate the amygdala-independent mechanisms leading to aversive emotional experiences, we retested two of these patients (B.G. and A.M.) to examine whether triggering palpitations and dyspnea via stimulation of non-chemosensory interoceptive channels would be sufficient to elicit panic anxiety. Participants rated their affective and sensory experiences following bolus infusions of either isoproterenol, a rapidly acting peripheral β-adrenergic agonist akin to adrenaline, or saline. Infusions were administered during two separate conditions: a panic induction and an assessment of cardiorespiratory interoception. Isoproterenol infusions induced anxiety in both patients, and full-blown panic in one (patient B.G.). Although both patients demonstrated signs of diminished awareness for cardiac sensation, patient A.M., who did not panic, reported a complete lack of awareness for dyspnea, suggestive of impaired respiratory interoception. These findings indicate that the amygdala may play a role in dynamically detecting changes in cardiorespiratory sensation. The induction of panic anxiety provides further evidence that the amygdala is not required for the conscious experience of fear induced via interoceptive sensory channels. We found that monozygotic twins with focal bilateral amygdala lesions report panic anxiety in response to intravenous infusions of isoproterenol, a β-adrenergic agonist similar to adrenaline. Heightened anxiety was evident in both twins, with one twin experiencing a panic attack. The twin who did not panic displayed signs of impaired cardiorespiratory interoception, including a complete absence of dyspnea sensation. These findings highlight that the amygdala is not strictly required for the experience of panic anxiety, and suggest that neural systems beyond the amygdala are also involved. Determining these additional systems could provide key neural modulation targets for future anxiolytic treatments. Copyright © 2016 Khalsa, Feinstein et al.

Using an innovative approach to study the neural bases of psychiatric disorders, this study investigated the behavioral, morphological and pharmacological bases of panic attack-induced responses in a prey-versus-coral snake paradigm. Mesocricetus auratus was chronically treated with intraperitoneal administration of the selective serotonin uptake inhibitor paroxetine or the gamma aminobutyric acid (GABA)/benzodiazepine receptor agonist alprazolam at three different doses and were then confronted with a venomous coral snake (Micrurus frontalis, Reptilia, Elapidae). The threatened rodents exhibited defensive attention, flat back approaches, defensive immobility, and escape defensive responses in the presence of the venomous snake, followed by increases in Fos protein in limbic structure neurons. Chronic administration of both paroxetine and alprazolam decreased these responses with morphological correlates between the panicolytic effect of both drugs administered at the highest dose and decreases in Fos protein-immunolabeled perikarya found in the amygdaloid complex, hypothalamus and periaqueductal gray matter columns, which are structures that make up the encephalic aversion system. These findings provide face, construct and predictive validities of this new experimental model of anxiety- and panic attack-like behavioral responses displayed by threatened prey confronted with venomous coral snakes.

Panic disorder is a highly prevalent neuropsychiatric disorder that shows co-occurrence with substance abuse. Here, we demonstrate that TrkC, the high-affinity receptor for neurotrophin-3, is a key molecule involved in panic disorder and opiate dependence, using a transgenic mouse model (TgNTRK3). Constitutive TrkC overexpression in TgNTRK3 mice dramatically alters spontaneous firing rates of locus coeruleus (LC) neurons and the response of the noradrenergic system to chronic opiate exposure, possibly related to the altered regulation of neurotrophic peptides observed. Notably, TgNTRK3 LC neurons showed an increased firing rate in saline-treated conditions and profound abnormalities in their response to met5-enkephalin. Behaviorally, chronic morphine administration induced a significantly increased withdrawal syndrome in TgNTRK3 mice. In conclusion, we show here that the NT-3/TrkC system is an important regulator of neuronal firing in LC and could contribute to the adaptations of the noradrenergic system in response to chronic opiate exposure. Moreover, our results indicate that TrkC is involved in the molecular and cellular changes in noradrenergic neurons underlying both panic attacks and opiate dependence and support a functional endogenous opioid deficit in panic disorder patients.

The false-suffocation hypothesis of panic disorder (Klein, 1993) suggested δ-opioid receptors as a possible source of the respiratory dysfunction manifested in panic attacks occurring in panic disorder (Preter and Klein, 2008). This study sought to determine if a lack of δ-opioid receptors in a mouse model affects respiratory response to elevated CO2, and whether the response is modulated by benzodiazepines, which are widely used to treat panic disorder. In a whole-body plethysmograph, respiratory responses to 5% CO2 were compared between δ-opioid receptor knockout mice and wild-type mice after saline, diazepam (1 mg/kg), and alprazolam (0.3 mg/kg) injection. The results show that lack of δ-opioid receptors does not affect normal response to elevated CO2, but does prevent benzodiazepines from modulating that response. Thus, in the presence of benzodiazepine agonists, respiratory responses to elevated CO2 were enhanced in δ-opioid receptor knockout mice compared to wild-type mice. This suggests an interplay between benzodiazepine receptors and δ-opioid receptors in regulating the respiratory effects of elevated CO2, which might be related to CO2 induced panic. PMID:21561601

Common and unique risk factors and comorbidity for 12-month mood and anxiety disorders among Canadians.

To explore the common and unique risk factors for mood and anxiety disorders. What sociodemographic, psychological, and physical risk factors are associated with mood and anxiety disorders and their comorbidities? What is the impact of multiple risk factors? Data from the Canadian Community Health Survey: Mental Health and Well-Being were analyzed. Appropriate sampling weights and bootstrap variance estimation were employed. Multiple logistic regression was used to estimate odds ratios and confidence intervals. The annual prevalence of any mood disorder was 5.2%, and of any anxiety disorder 4.7%. Major depressive episode was the most prevalent mood and anxiety disorder (4.8%), followed by social phobia, panic disorder, mania, and agoraphobia. Among people with mood and anxiety disorders, 22.4% had 2 or more disorders. Risk factors common to mood and anxiety disorders were being young, having lower household income, being unmarried, experiencing greater stress, having poorer mental health, and having a medical condition. Unique risk factors were found: major depressive episode and social phobia were associated with being born in Canada; panic disorder was associated with being Caucasian; lower education was associated with panic and agoraphobia; and poor physical health was associated with mania and agoraphobia. People who were young, unmarried, not fully employed, and had a medical condition, greater stress, poorer self-rated mental health, and dissatisfaction with life, were more likely to have a comorbid mood and (or) anxiety disorder. As the number of common risk factors increases, the probability of having mood and anxiety disorders also increases. Common and unique risk factors exist for mood and anxiety disorders. Risk factors are additive in increasing the likelihood of disease.

The contributions of disorder severity, comorbidity and interpersonal variables to therapists' adherence to a cognitive-behavioural treatment (CBT) manual were tested. Thirty-eight patients received panic control therapy (PCT) for panic disorder. Trained observers watching videotapes of the sixth session of a 24-session protocol rated therapists' adherence to PCT and their use of interventions from outside the CBT model. Different observers rated patients' behavioural resistance to therapy in the same session using the client resistance code. Interview measures obtained before treatment included the Panic Disorder Severity Scale, the anxiety disorders interview schedule for Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and the structured clinical interview for DSM-IV, Axis II. Questionnaire measures were the anxiety sensitivity index at intake, and, at session 2, the therapist and client versions of the working alliance inventory-short form. The higher the patients' resistance and the more Axis II traits a patient had, the less adherent the therapist. Moreover, the more resistant the client, the more therapists resorted to interventions from outside the CBT model. Stronger therapist and patient alliance was also generally related to better adherence, but these results were somewhat inconsistent across therapists. Pretreatment disorder severity and comorbidity were not related to adherence. Interpersonal variables, particularly behavioural resistance to therapy, are related to therapists' ability to adhere to a treatment manual and to their use of interventions from outside of the CBT model. Copyright © 2015 John Wiley & Sons, Ltd. Patients' behavioural resistance to therapy may make it more difficult for cognitive-behavioural clinicians to adhere to a structured treatment protocol and more likely for them to borrow interventions from outside the CBT model. Patients' Axis II traits may make adherence to treatment CBT protocol more difficult, although whether this is true varies across therapists. Therapists' adherence to a structured protocol and borrowing from outside of the CBT model do not appear to be affected by disorder severity or Axis I comorbidity.

Manic switch is a relevant issue when treating bipolar depression. Some risk factors have been suggested, but unequivocal findings are lacking. We therefore investigated predictors of switch from depression to mania in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) sample. Manic switch was defined as a depressive episode followed by a (hypo)manic or mixed episode within the following 12 weeks. We assessed possible predictors of switch using generalized linear mixed models (GLMM). 8403 episodes without switch and 512 episodes with switch (1720 subjects) were included in the analysis. Several baseline variables were associated with a higher risk of switch. They were younger age, previous history of: rapid cycling, severe manic symptoms, suicide attempts, amphetamine use and some pharmacological and psychotherapeutic treatments. During the current depressive episode, the identified risk factors were: any possible mood elevation, multiple mania-associated symptoms with at least moderate severity, and comorbid panic attacks. In conclusion, our study suggests that both characteristics of the disease history and clinical features of the current depressive episode may be risk factors for manic switch.

Introduction This study investigated co-morbidities, level of disability, service utilization and demographic correlates of panic disorder (PD) among African Americans, Caribbean blacks and non-Hispanic white Americans. Methods Data are from the National Survey of American Life (NSAL) and the National Comorbidity Survey-Replication (NCS-R). Results Non-Hispanic whites are the most likely to develop PD across the lifespan compared to the black subgroups. Caribbean blacks were found to experience higher levels of functional impairment. There were no gender differences found in prevalence of PD in Caribbean blacks, indicating that existing knowledge about who is at risk for developing PD (generally more prevalent in women) may not be true among this subpopulation. Furthermore, Caribbean blacks with PD were least likely to use mental health services compared to African Americans and non-Hispanic whites. Conclusion This study demonstrates that PD may affect black ethnic subgroups differently, which has important implications for understanding the nature and etiology of the disorder. PMID:22983664

To investigate predictors and moderators of treatment outcome by comparing immediate face-to-face cognitive behavioral therapy (FtF-CBT) to a Stepped Care treatment model comprising three steps: Psychoeducation, Internet-delivered CBT, and FtF-CBT for panic disorder (PD) and social anxiety disorder (SAD). Patients (N = 173) were recruited from nine public mental health out-patient clinics and randomized to immediate FtF-CBT or Stepped Care treatment. Characteristics related to social functioning, impairment from the anxiety disorder, and comorbidity was investigated as predictors and moderators by treatment format and diagnosis in multiple regression analyses. Lower social functioning, higher impairment from the anxiety disorder, and a comorbid cluster C personality disorder were associated with significantly less improvement, particularly among patients with PD. Furthermore, having a comorbid anxiety disorder was associated with a better treatment outcome among patients with PD but not patients with SAD. Patients with a comorbid depression had similar outcomes from the different treatments, but patients without comorbid depression had better outcomes from immediate FtF-CBT compared to guided self-help. In general, the same patient characteristics appear to be associated with the treatment outcome for CBT provided in low- and high-intensity formats when treated in public mental health care clinics. The findings suggest that patients with lower social functioning and higher impairment from their anxiety disorder benefit less from these treatments and may require more adapted and extensive treatment.

Heightened sensitivity to threat and reduced sensitivity to reward are potential mechanisms of dysfunction in anxiety and depressive disorders, respectively. However, few studies have simultaneously examined whether these mechanisms are unique or common to these disorders. In this study, sensitivity to predictable and unpredictable threat (measured by startle response during threat anticipation) and sensitivity to reward (measured by frontal electroencephalographic [EEG] asymmetry during reward anticipation) were assessed in 4 groups (N = 191): those with (1) panic disorder (PD) without a lifetime history of depression, (2) major depression (MDD) without a lifetime history of an anxiety disorder, (3) comorbid PD and MDD, and (4) controls. General distress/negative temperament (NT) was also assessed via self-report. Results indicated that PD (with or without comorbid MDD) was uniquely associated with heightened startle to predictable and unpredictable threat, and MDD (with or without comorbid PD) was uniquely associated with reduced frontal EEG asymmetry. Both psychophysiological measures of threat and reward sensitivity were stable on retest approximately 9 days later in a subsample of participants. Whereas the comorbid group did not respond differently on the tasks relative to the PD-only and MDD-only groups, they did report greater NT than these 2 groups (which did not differ from each other). Results suggest that heightened sensitivity to threat and reduced sensitivity to reward may be specific components of PD and MDD, respectively. In addition, relative to noncomorbid depression and PD, comorbid MDD and PD may be characterized by heightened NT, but not abnormal levels of these “specific” components. PMID:23148783

Differences in mental health outcomes by acculturation status following a major urban disaster.

A number of studies have assessed the association between acculturation and psychological outcomes following a traumatic event. Some suggest that low acculturation is associated with poorer health outcomes, while others show no differences or that low acculturation is associated with better outcomes. One year after the terrorist attacks on the World Trade Center, we surveyed a multi-ethnic population of New York City adults (N= 2,368). We assessed posttraumatic stress disorder (PTSD), major depression, panic attack, anxiety symptoms, and general physical and mental health status. We classified study respondents into "low," "moderate," or "high" acculturation, based on survey responses. Bivariate results indicated that low acculturation individuals were more likely to experience negative life events, have low social support, and less likely to have pre-disaster mental health disorders. Those in the low acculturation group were also more likely to experience post-disaster perievent panic attacks, have higher anxiety, and have poorer mental health status. However, using logistic regression to control for confounding, and adjusting for multiple comparisons, we found that none of these outcomes were associated with acculturation status. Thus, our study suggests that acculturation was not associated with mental health outcomes following a major traumatic event.

2012-01-01

Background Panic disorder is common (5% prevalence) and females are twice as likely to be affected as males. The heritable component of panic disorder is estimated at 48%. Glutamic acid dehydrogenase GAD1, the key enzyme for the synthesis of the inhibitory and anxiolytic neurotransmitter GABA, is supposed to influence various mental disorders, including mood and anxiety disorders. In a recent association study in depression, which is highly comorbid with panic disorder, GAD1 risk allele associations were restricted to females. Methodology/Principal Findings Nineteen single nucleotide polymorphisms (SNPs) tagging the common variation in GAD1 were genotyped in two independent gender and age matched case-control samples (discovery sample n = 478; replication sample n = 584). Thirteen SNPs passed quality control and were examined for gender-specific enrichment of risk alleles associated with panic disorder by using logistic regression including a genotype×gender interaction term. The latter was found to be nominally significant for four SNPs (rs1978340, rs3762555, rs3749034, rs2241165) in the discovery sample; of note, the respective minor/risk alleles were associated with panic disorder only in females. These findings were not confirmed in the replication sample; however, the genotype×gender interaction of rs3749034 remained significant in the combined sample. Furthermore, this polymorphism showed a nominally significant association with the Agoraphobic Cognitions Questionnaire sum score. Conclusions/Significance The present study represents the first systematic evaluation of gender-specific enrichment of risk alleles of the common SNP variation in the panic disorder candidate gene GAD1. Our tentative results provide a possible explanation for the higher susceptibility of females to panic disorder. PMID:22662185

Novel investigational therapeutics for panic disorder.

2015-04-01

Panic disorder (PD) is a common disabling anxiety disorder associated with relevant social costs. Effective anti-panic medications exist but have several drawbacks. From a clinical perspective, there is still a strong unmet need for more effective, faster acting and more tolerable therapeutic treatments. The authors review the available results on novel mechanism-based anti-panic drugs that are under investigation in animal studies up to Phase II studies. The preclinical studies investigated include: the modulators of the glutamate/orexin/cannabinoid systems, corticotrophin-releasing factor 1 (CRF1)/arginine vasopressine V₁B/angiotensin II receptor antagonists and neuropeptide S. The Phase I/II studies investigated include: the modulators of the glutamate system, isoxazoline derivative, translocator protein (18 kDa) ligands and CRF1/neurokinin receptor antagonists. There has been little progress in recent times. However, glutamate- and orexin-related molecular targets may represent very promising opportunities for treating panic attacks. Very preliminary findings suggest that the antagonists of CRF1 and A-II receptors may have anti-panic properties. However, new medications for PD are far from being implemented in clinical use. The reasons are multiple, including: the heterogeneity of the disorder, the translational validity of animal models and the insufficient use of biomarkers in preclinical/clinical studies. Nevertheless, biomarker-based strategies, pharmacogenomics, 'personalized psychiatry' and the NIH's Research Domain Criteria approach could help to remove those obstacles limiting drug development.

We aimed at providing estimates of mortality associated with cardiometabolic comorbidity and incident readmission from cardiometabolic as compared with noncardiometabolic conditions after a first transient ischemic attack. Between 2000 and 2015, patients hospitalized for a first transient ischemic attack were examined for cardiometabolic comorbidities (diabetes mellitus, coronary artery disease, heart failure, and atrial fibrillation), 5-year incident hospitalization, and time to death. Of 251 patients with transient ischemic attack, 134 (53%) had at least 1 and 55 (22%) had at least 2 cardiometabolic conditions. By 5 years, 491 readmissions (134 [27%] cardiometabolic and 357 [73%] noncardiometabolic) and 75 deaths (27 [36%] cardiometabolic and 47 [64%] noncardiometabolic) were observed. Mortality was increased with any concurrent cardiometabolic comorbidity (hazard ratio, 1.89; 95% confidence interval, 1.17-3.03; P =0.0089) with multiplicative mortality risk from a combination of coronary artery disease and heart failure. Each hospitalization was associated with a 1.5-fold risk of death (95% confidence interval, 1.37-1.64; P <0.0001). Risk of cardiometabolic and noncardiometabolic mortality was correlated with the corresponding category-specific readmission. Among patients hospitalized for first transient ischemic attack, 5-year mortality is associated with concurrent cardiometabolic comorbidity and rates of subsequent hospitalization. © 2018 American Heart Association, Inc.

Laboratory, clinical and therapeutic features of respiratory panic disorder subtype.

It is our aim to elaborate on the new developments in regard to the respiratory subtype (RS) of panic disorder (PD) since it was first described. We will present psychopathological features, diagnostic criteria, genetic and physiopathological hypotheses, as well as therapeutic and prognostic characteristics. Two searches were performed in the Thomson Reuters Web of Knowledge (http://wokinfo.com/): 1 - search terms: "panic disorder" AND ("respiratory symptom" OR "respiratory symptoms" OR "respiratory subtype" OR "respiratory panic" OR "cardiorespiratory"); 2 - all articles citing Briggs and colleagues' 1993 article "Subtyping of Panic Disorder by Symptom Profile" (Br J Psychiatry 1993;163: 201-9). Only those articles involving human subjects and written English were included. In comparison with patients of the non-respiratory subtype (NRS), RS patients showed greater familial history of PD, and higher comorbidity rates for anxiety disorders and depressive disorders. These patients were also more sensitive to CO2, hyperventilation and caffeine. Certain characteristics, such as heightened sensitivity to CO2 and the higher incidence of a family history of PD, clearly distinguished the Respiratory Subtype patients from the Non-Respiratory. Nonetheless, some studies failed to demonstrate differential responses to pharmacological treatment and CBT across the subtypes. RS patients seem to respond faster than NRS to pharmacological treatment with antidepressants and benzodiazepines, but more studies are needed to confirm this finding.

To ascertain rates of panic, obsessive-compulsive (OCD) and social phobic disorders among adolescents with bipolar disorder (BP), unipolar major depressive disorder (MDD) and psychiatric comparison patients, to assess their relationships to suicidality, psychosis, comorbidity patterns and familiality. The first author (SCD) interviewed 313 Latino adolescents using a structured interview based on the SCID. Family history was ascertained by live interview or interview by proxy. Patients were classified as BP, MDD, or non-affectively ill comparison controls (CC). Data regarding suicidality and psychosis were collected. Regression analysis was used to test associations and control for confounding effects. Positive likelihood ratios were used to measure the dose-response relationships between number of anxiety disorders and measures of severity of illness and familial loading for affective illness. Of the total sample, 36.7% were BP, 44.7% MDD and 18.5% CC. In BP vs. MDD the odds of panic disorder were 4.4, of OCD 5.1, and of social phobia 3.3. MDD, in turn, were more likely to have these disorders than CC. BP (but not MDD) with panic disorder and social phobia, were more likely to have suicidal ideation; among the anxiety disorders, only social phobia was associated with having greater odds of suicide attempts. Among BP and MDD, patients with all three anxiety disorders were more likely to be psychotic. Presence of any mood disorder among first-degree relatives substantially increased the odds of having panic disorder and social phobia. The presence of one comorbid anxiety disorder increased the odds of having another. Finally, there were dose-response relationships between number of anxiety disorders and measures of severity of illness and familial loading for affective illness. Single interviewer using the SCID; cross sectional exploratory study. BP adolescents have a greater anxiety disorder burden than their MDD counterparts. The results are compatible with the hypothesis that heavy familial-genetic loading for affective illness in juveniles is associated with bipolarity, cumulative anxiety disorder comorbidity, suicidality and psychosis. These observations are in line with pioneering psychopathologic observation in the early 1900s by two French psychiatrists, Gilbert Ballet and Pierre Kahn, who saw common ground between what until then had been considered the distinct categories of the neuroses and cyclothymic (circular) psychoses. This perspective has much in common with current complex genetic models of anxious diatheses in bipolar disorder.

This cross-sectional European multicenter study examined the association between major depressive disorder (MDD) and comorbid obsessive-compulsive disorder (OCD). Socio-demographic, clinical, and treatment features of 1346 adult MDD patients were compared between MDD subjects with and without concurrent OCD using descriptive statistics, analyses of covariance (ANCOVA), and binary logistic regression analyses. We determined a point prevalence of comorbid OCD in MDD of 1.65%. In comparison to the MDD control group without concurrent OCD, a higher proportion of patients in the MDD + comorbid OCD group displayed concurrent panic disorder (31.81% vs 7.77%, p<.001), suicide risk (52.80% vs 44.81%, p=.04), polypsychopharmacy (95.45% vs 60.21%, p=.001), and augmentation treatment with antipsychotics (50.00% vs 25.46%, p=.01) and benzodiazepines (68.18% vs 33.31%, p=.001). Moreover, they were treated with higher mean doses of their antidepressant drugs (in fluoxetine equivalents: 48.99mg/day ± 18.81 vs 39.68mg/day ± 20.75, p=.04). In the logistic regression analyses, comorbid panic disorder (odds ratio (OR)=4.17, p=.01), suicide risk (OR=2.56, p=.04), simultaneous treatment with more psychiatric drugs (OR=1.51, p=<.05), polypsychopharmacy (OR=14.29, p=.01), higher antidepressant dosing (OR=1.01, p=<.05), and augmentation with antipsychotics (OR=2.94, p=.01) and benzodiazepines (OR=4.35, p=.002) were significantly associated with comorbid OCD. In summary, our findings suggest that concurrent OCD in MDD (1) has a low prevalence rate compared to the reverse prevalence rates of comorbid MDD in OCD, (2) provokes higher suicide risk, and (3) is associated with a characteristic prescription pattern reflected by a high amount of polypsychopharmaceutical treatment strategies comprising particularly augmentation with antipsychotics and benzodiazepines.

The current study investigated the main and interactive effects of emotion dysregulation and distress tolerance in relation to panic-relevant variables among daily smokers. The sample consisted of 172 adults (61.2% male; Mage = 31.58, SD = 11.51), who reported smoking an average of 15.99 cigarettes per day (SD = 10.00). Results indicated that both emotion dysregulation and distress tolerance were significantly related to interoceptive fear and agoraphobia. Additionally, emotion dysregulation, but not distress tolerance, was significantly related to anxiety sensitivity. All effects were evident above and beyond the variance accounted for by average cigarettes per day, tobacco-related physical illness, and panic attack history. The interaction between emotion dysregulation and distress tolerance significantly predicted interoceptive and agoraphobic fears as well as the cognitive component of anxiety sensitivity. Such findings underscore the importance of emotion dysregulation and distress tolerance in regard to panic-specific fear and expectancies about anxiety-related sensations among daily smokers.

We estimated the prevalence, severity, and correlates of burden and distress in caregivers of patients with panic disorder and agoraphobia. The instruments used in this cross-sectional study with 40 caregivers and 40 outpatients were Carer Burden Interview (CBI), Family Burden Interview Schedule (FBIS-BR), Self-Reporting Questionnaire (SRQ), Panic and Agoraphobia Scale (PAS), and Mini-international Neuropsychiatric Interview. Bivariate analyses were followed by regression analyses. The patients' mean PAS score was 29.6, and the mean scores in the caregivers' burden scales were 27 (CBI) and 1.64 (FBIS-BR). Distress (or common mental disorder [CMD]) occurred in 37.5% and was associated with higher burden. In the multivariate analysis, the SRQ score was predicted by female sex and worse self-evaluation of health, the CBI score by CMD and public service, the FBIS-BR score by CMD and not living with the patient, the FBIS-objective score by CMD and being employed, the FBIS-subjective score by CMD, and the level of worry by the severity of patients' avoidance and panic attacks.

The Interaction of Nicotine Withdrawal and Panic Disorder in the Prediction of Panic-relevant Responding to a Biological Challenge

2013-01-01

The current investigation evaluated nicotine withdrawal symptoms elicited by 12 hours of smoking deprivation on anxious and fearful responding to bodily sensations among daily smokers with and without Panic Disorder (PD). It was hypothesized that smokers with PD who were experiencing greater levels of nicotine withdrawal would experience the greatest levels of fearful responding to, and delayed recovery from, a 10% carbon dioxide-enriched air (CO2) biological challenge procedure. Participants were 58 adults who reported smoking 19.72 cigarettes daily (SD = 7.99). Results indicated that nicotine withdrawal and PD status interacted to predict greater post-challenge panic attack symptoms. Also, individuals with PD initially evidenced a quicker decrease in subjective anxiety following the challenge, but their rate of recovery decelerated over time as compared to those without PD. There was, however, no significant interaction for change in subjective anxiety pre- to post-challenge. Results are discussed in relation to the role of nicotine withdrawal in anxious and fearful responding for smokers with PD. PMID:22867297

Consecutive Cambodian refugees attending a psychiatric clinic were assessed for the presence and severity of current--i.e., at least one episode in the last month--neck-focused panic. Among the whole sample (N=130), in a logistic regression analysis, the Anxiety Sensitivity Index (ASI; odds ratio=3.70) and the Clinician-Administered PTSD Scale (CAPS; odds ratio=2.61) significantly predicted the presence of current neck panic (NP). Among the neck panic patients (N=60), in the linear regression analysis, NP severity was significantly predicted by NP-associated flashbacks (beta=.42), NP-associated catastrophic cognitions (beta=.22), and CAPS score (beta=.28). Further analysis revealed the effect of the CAPS score to be significantly mediated (Sobel test [Baron, R. M., & Kenny, D. A. (1986). The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations.

In the care of traumatized Cambodian refugees, NP severity, as well as NP-associated flashbacks and catastrophic cognitions, should be specifically assessed and treated.

1988-04-01

Twenty-three patients meeting DSM-III criteria for agoraphobia with panic attacks and 14 age-, race-, and sex-matched nonanxious controls were tested in the laboratory and on a test walk in a shopping mall. The patients were tested before and after about 15 weeks of treatment with placebo and exposure therapy, imipramine and exposure therapy, or imipramine and initial antiexposure instructions. Controls were tested twice at a similar interval, but without any treatment. On test day 1, patients compared to controls showed higher average heart rate and skin conductance levels and greater numbers of skin conductance fluctuations in the laboratory, and higher heart rates before and during the test walk. Between pretreatment and posttreatment tests, clinical ratings improved and skin conductance levels decreased in all treatment groups. Heart rate levels in the laboratory, on the other hand, decreased in patients on placebo and rose in patients on imipramine. Thus, imipramine compromises the usefulness of heart rate as a measure of emotional arousal. Higher pretreatment heart rates predicted greater clinical improvement.

In-situation safety behaviors play an important role in the maintenance of anxiety because they prevent patients from experiencing unambiguous disconfirmation of their unrealistic beliefs about feared catastrophes. Strategies for identifying particular safety behaviors, however, have not been sufficiently investigated. The aims of the present study were to (i) develop a comprehensive list of safety behaviors seen in panic disorder and to examine their frequency; and (ii) correlate the safety behaviors with panic attack symptoms, agoraphobic situations and treatment response. The subjects consisted of 46 consecutive patients who participated in group cognitive behavioral treatment (CBT) for panic disorder. All the patients completed a Safety Behavior List that was developed based on experiences with panic disorder patients. Carrying medications, distracting attention, carrying a plastic bottle, and drinking water were reported by more than half of the patients. The strongest correlations between panic symptoms and safety behaviors were found between symptoms of derealization and listening to music with headphones, paresthesia and pushing a cart while shopping, and nausea and squatting down. The strongest association between agoraphobic situations and safety behaviors was found between the fear of taking a bus or a train alone and moving around. Staying still predicted response to the CBT program, while concentrating on something predicted lack of response. An approximate guideline has been developed for identifying safety behaviors among patients with panic disorder and should help clinicians use CBT more effectively for these patients. © 2013 The Authors.

Prior studies on the depression-heart disease association have not usually used diagnostic measures of depression, or taken other mental disorders into consideration. As a result, it is not clear whether the association between depression and heart disease onset reflects a specific association, or the comorbidity between depression and other mental disorders. Additionally, the relative magnitude of associations of a range of mental disorders with heart disease onset is unknown. Face-to-face household surveys were conducted in 19 countries (n=52,095; person years=2,141,194). The Composite International Diagnostic Interview retrospectively assessed lifetime prevalence and age at onset of 16 DSM-IV mental disorders. Heart disease was indicated by self-report of physician's diagnosis, or self-report of heart attack, together with their timing (year). Survival analyses estimated associations between first onset of mental disorders and subsequent heart disease onset. After comorbidity adjustment, depression, panic disorder, specific phobia, post-traumatic stress disorder and alcohol use disorders were associated with heart disease onset (ORs 1.3-1.6). Increasing number of mental disorders was associated with heart disease in a dose-response fashion. Mood disorders and alcohol abuse were more strongly associated with earlier onset than later onset heart disease. Associations did not vary by gender. Depression, anxiety and alcohol use disorders were significantly associated with heart disease onset; depression was the weakest predictor. If confirmed in future prospective studies, the breadth of psychopathology's links with heart disease onset has substantial clinical and public health implications. © 2013.

Panic attacks (PAs), the core feature of panic disorder, represent a common phenomenon in the general adult population and are associated with a considerable decrease in quality of life and high health care costs. To date, the underlying pathophysiology of PAs is not well understood. A unique feature of PAs is that they represent a rare example of a psychopathological phenomenon that can be reliably modeled in the laboratory in panic disorder patients and healthy volunteers. The most effective techniques to experimentally trigger PAs are those that acutely disturb the acid-base homeostasis in the brain: inhalation of carbon dioxide (CO2), hyperventilation, and lactate infusion. This review particularly focuses on the use of CO2 inhalation in humans and rodents as an experimental model of panic. Besides highlighting the different methodological approaches, the cardio-respiratory and the endocrine responses to CO2 inhalation are summarized. In addition, the relationships between CO2 level, changes in brain pH, the serotonergic system, and adaptive physiological and behavioral responses to CO2 exposure are presented. We aim to present an integrated psychological and neurobiological perspective. Remaining gaps in the literature and future perspectives are discussed. Copyright © 2015 Elsevier Ltd.

A clinical study of autogenic training-based behavioral treatment for panic disorder.

PubMed

Sakai, M

1996-03-01

The present study investigated the effect of autogenic training-based behavioral treatment for panic disorder and identified the predictors of treatment outcome. Thirty-four patients meeting DSM-III-R criteria for panic disorder received autogenic training-based behavioral treatment from October 1981 to December 1994. They were treated individually by the author. The medical records of the patients were investigated for the purpose of this study. The results showed that this autogenic training-based behavioral treatment had successful results. Fifteen patients were cured, nine much improved, five improved, and five unchanged at the end of the treatment. Improvement trends were found as for the severity of panic attack and the severity of agoraphobic avoidance. No consistent findings about predictors emerged when such pretreatment variables as demographics and severity of symptoms were used to predict the outcome. Also, three treatment variables showed useful predictive power. First, practicing the second standard autogenic training exercise satisfactorily predicted better outcomes. Second, application of in vivo exposure was found to be positively associated with the treatment outcome in patients with agoraphobic avoidance. Third, longer treatment periods were associated with better outcomes. These findings suggested that the autogenic training-based behavioral treatment could provide relief to the majority of panic disorder patients.

An Attempt to Target Anxiety Sensitivity via Cognitive Bias Modification

Our goals in the present study were to test an adaptation of a Cognitive Bias Modification program to reduce anxiety sensitivity, and to evaluate the causal relationships between interpretation bias of physiological cues, anxiety sensitivity, and anxiety and avoidance associated with interoceptive exposures. Participants with elevated anxiety sensitivity who endorsed having a panic attack or limited symptom attack were randomly assigned to either an Interpretation Modification Program (IMP; n = 33) or a Control (n = 32) condition. During interpretation modification training (via the Word Sentence Association Paradigm), participants read short sentences describing ambiguous panic-relevant physiological and cognitive symptoms and were trained to endorse benign interpretations and reject threatening interpretations associated with these cues. Compared to the Control condition, IMP training successfully increased endorsements of benign interpretations and decreased endorsements of threatening interpretations at visit 2. Although self-reported anxiety sensitivity decreased from pre-selection to visit 1 and from visit 1 to visit 2, the reduction was not larger for the experimental versus control condition. Further, participants in IMP (vs. Control) training did not experience less anxiety and avoidance associated with interoceptive exposures. In fact, there was some evidence that those in the Control condition experienced less avoidance following training. Potential explanations for the null findings, including problems with the benign panic-relevant stimuli and limitations with the control condition, are discussed. PMID:25692491

The goal of this study was to examine the associations between specific anxiety disorders and the risk of major depressive disorder and to explore the role of various clinical characteristics of anxiety disorders in these relationships using a prospective, longitudinal design. The data are from a 4-year prospective, longitudinal community study, which included both baseline and follow-up survey data on 2548 adolescents and young adults aged 14 to 24 years at baseline. DSM-IV diagnoses were made using the Munich-Composite International Diagnostic Interview. The presence at baseline of any anxiety disorder (odds ratio [OR] = 2.2 [95% CI = 1.6 to 3.2]) and each of the anxiety disorders (specific phobia, OR = 1.9 [95% CI = 1.3 to 2.8]; social phobia, OR = 2.9 [95% CI = 1.7 to 4.8]; agoraphobia, OR = 3.1 [95% CI = 1.4 to 6.7]; panic disorder, OR = 3.4 [95% CI = 1.2 to 9.0]; generalized anxiety disorder, OR = 4.5 [95% CI = 1.9 to 10.3]) was associated with a significantly (p <.05) increased risk of first onset of major depressive disorder. These associations remained significant after we adjusted for mental disorders occurring prior to the onset of the anxiety disorder, with the exception of the panic disorder association. The following clinical characteristics of anxiety disorders were associated with a significantly (p <.05) increased risk of developing major depressive disorder: more than 1 anxiety disorder, severe impairment due to the anxiety disorder, and comorbid panic attacks. In the final model, which included all clinical characteristics, severe impairment remained the only clinical characteristic that was an independent predictor of the development of major depressive disorder (OR = 2.2 [95% CI = 1.0 to 4.4]). Our findings suggest that anxiety disorders are risk factors for the first onset of major depressive disorder. Although a number of clinical characteristics of anxiety disorders appear to play a role in the association between anxiety disorders and depression, severe impairment is the strongest predictor of major depressive disorder.

Cognitive-behavioral therapy is frequently indicated for panic disorder. The aim here was to evaluate the efficacy of a model for cognitive-behavioral therapy for treating panic disorder with agoraphobia. Randomized clinical trial at Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro. A group of 50 patients with a diagnosis of panic disorder with agoraphobia was randomized into two groups to receive: a) cognitive-behavioral therapy with medication; or b) medication (tricyclic antidepressants or selective serotonin reuptake inhibitors). Although there was no difference between the groups after the treatment in relation to almost all variables with the exception of some items of the Sheehan disability scale and the psychosocial and environmental problems scale, the patients who received the specific therapy presented significant reductions in panic attacks, anticipatory anxiety, agoraphobia avoidance and fear of body sensations at the end of the study, in relation to the group without the therapy. On the overall functioning assessment scale, overall wellbeing increased from 60.8% to 72.5% among the patients in the group with therapy, thus differing from the group without therapy. Although both groups responded to the treatment and improved, we only observed significant differences between the interventions on some scales. The association between specific cognitive-behavioral therapy focusing on somatic complaints and pharmacological treatment was effective among this sample of patients with panic disorder and the response was similar in the group with pharmacological treatment alone.

Panic disorder with agoraphobia is characterized by panic attacks and anxiety in situations where escape might be difficult. However, neuroimaging studies specifically focusing on agoraphobia are rare. Here we used functional magnetic resonance imaging (fMRI) with disorder-specific stimuli to investigate the neural substrates of agoraphobia. We compared the neural activations of 72 patients suffering from panic disorder with agoraphobia with 72 matched healthy control subjects in a 3-T fMRI study. To isolate agoraphobia-specific alterations we tested the effects of the anticipation and perception of an agoraphobia-specific stimulus set. During fMRI, 48 agoraphobia-specific and 48 neutral pictures were randomly presented with and without anticipatory stimulus indicating the content of the subsequent pictures (Westphal paradigm). During the anticipation of agoraphobia-specific pictures, stronger activations were found in the bilateral ventral striatum and left insula in patients compared with controls. There were no group differences during the perception phase of agoraphobia-specific pictures. This study revealed stronger region-specific activations in patients suffering from panic disorder with agoraphobia in anticipation of agoraphobia-specific stimuli. Patients seem to process these stimuli more intensively based on individual salience. Hyperactivation of the ventral striatum and insula when anticipating agoraphobia-specific situations might be a central neurofunctional correlate of agoraphobia. Knowledge about the neural correlates of anticipatory and perceptual processes regarding agoraphobic situations will help to optimize and evaluate treatments, such as exposure therapy, in patients with panic disorder and agoraphobia.

This study examined the relationships between changes in symptoms and changes in quality of life (QOL) during cognitive-behavioral therapy (CBT) for panic disorder (PD). We treated 198 PD patients with group CBT in Japan. Using multiple regression analysis, we examined the associations between changes in QOL and changes in PD symptoms or comorbid psychological symptoms during CBT. Changes in anticipatory anxiety, agoraphobic fear/avoidance, and somatization were significant predictors of changes in some aspects of QOL. It might be useful to decrease somatization, anticipatory anxiety, and agoraphobic fear to improve QOL in CBT for PD. © 2016 John Wiley & Sons Australia, Ltd.

Alarming somatic symptoms, in particular, cardiovascular symptoms, are the characteristic feature of panic attacks. Increased cardiac mortality and morbidity have been found in these patients. Power spectral analysis of electrocardiogram R-R intervals is known to be a particularly successful tool in the detection of autonomic instabilities in various clinical disorders. Our study aimed to compare patients with panic disorder and healthy controls in heart rate variation (HRV) parameters (very-low-frequency [VLF], low-frequency [LF], and high-frequency [HF] band components of R-R interval) in baseline and during the response to the mental task. We assessed psychophysiological variables in 33 patients with panic disorder (10 men, 23 women; mean age 35.9±10.7 years) and 33 age- and gender-matched healthy controls (10 men, 23 women; mean age 35.8±12.1 years). Patients were treatment naïve. Heart rate, blood pressure, muscle tension, and HRV in basal conditions and after the psychological task were assessed. Power spectrum was computed for VLF (0.003-0.04 Hz), LF (0.04-0.15 Hz), and HF (0.15-0.40 Hz) bands using fast Fourier transformation. In the baseline period, the VLF band was significantly lower in panic disorder group compared to controls ( p <0.005). In the period of mental task, the LF/HF ratio was significantly higher in panic disorder patients compared to controls ( p <0.05). No significant differences were found in the remaining parameters. There was a significant difference in ΔHF and ΔLF/HF ratio between patients and controls, with Δ increasing in patients and decreasing in controls. These findings revealed that patients suffering from panic disorder were characterized by relative sympathetic dominance (reactivity) in response to mental stress compared with healthy controls.

The present study examined whether early life maternal separation (MS), a model of childhood separation anxiety, predisposes to panic at adulthood. For this purpose, male pups were submitted to 3-h daily maternal separations along postnatal (PN) days of either the 'stress hyporesponsive period' (SHRP) from PN4 to PN14 (MS11) or throughout lactation from PN2 to PN21 (MS20). Pups were further reunited to conscious (CM) or anesthetized (AM) mothers to assess the effect of mother-pup interaction upon reunion. Controls were subjected to brief handling (15 s) once a day throughout lactation (BH20). As adults (PN60), rats were tested for the thresholds to evoke panic-like behaviors upon electrical stimulation of dorsal periaqueductal gray matter and exposed to an elevated plus-maze, an open-field, a forced swim and a sucrose preference test. A factor analysis was also performed to gain insight into the meaning of behavioral tests. MS11-CM rather than MS20-CM rats showed enhanced panic responses and reductions in both swimming and sucrose preference. Panic facilitations were less intense in mother-neglected rats. Although MS did not affect anxiety, MS11-AM showed robust reductions of defecation in an open-field. Factor analysis singled out anxiety, hedonia, exploration, coping and gut activity. Although sucrose preference and coping loaded on separate factors, appetite (adult weight) correlated with active coping in both forced swim and open-field (central area exploration). Concluding, whereas 3h-daily maternal separations during SHRP increased rat's susceptibility to experimental panic attacks, separations throughout lactation had no effects on panic and enhanced active coping.

Background Although treatment of depression has increased in recent years, long delays commonly separate disorder onset from first treatment contact. Objectives This study evaluates the effects of psychiatric comorbidities and socio-demographic characteristics on lifetime treatment seeking and speed to first treatment contact for major depressive disorder (MDD). Measures A cross-sectional epidemiological survey including retrospective structured assessments of DSM-IV MDD and other psychiatric disorders, respondent age at disorder onset, and age at first treatment contact. Subjects A nationally representative sample of 5,958 adults aged ≥18 years residing in households and group quarters who met lifetime criteria for MDD. Data Analysis The percentage of respondents with lifetime MDD who reported ever seeking treatment is reported overall and stratified by sociodemographic characteristics. Unadjusted and adjusted hazard ratios are presented of time to first depression treatment seeking by sociodemographic characteristics and comorbid psychiatric disorders. Results A majority (61.3%) of respondents with MDD reported having sought treatment for depression at some point in their lives. Time to first depression treatment contact was significantly related to the occurrence of comorbid panic disorder (AHR=2.01, 95%CI=1.69–2.39), generalized anxiety disorder (AHR=1.55, 95%CI=1.33–1.81), drug dependence (AHR=1.54, 95%CI=1.06–2.26), dysthymic disorder (AHR=1.54, 95%CI=1.35–1.76), and PTSD (AHR=1.34, 95%CI=1.13–1.59) and inversely related to male sex (AHR=0.74, 95%CI=0.66–0.82) and black race/ethnicity (AHR=0.69, 95%CI=0.59–0.81). Conclusion Comorbid psychiatric disorders, especially panic, generalized anxiety, substance use, and dysthymic disorders, appear to play an important role in accelerating treatment seeking for MDD. Outreach efforts should include a focus on depressed individuals without complicating psychiatric comorbidities. PMID:22186769

Major depressive disorder (MDD), panic disorder, and social anxiety disorder are among the most prevalent and frequently co-occurring psychiatric disorders in adults and may have, at least in part, a common etiology. To identify the unique and shared neuroanatomical profile of depression and anxiety, controlling for illness severity, medication use, sex, age of onset, and recurrence. Cross-sectional study. Netherlands Study of Depression and Anxiety. Outpatients with MDD (n = 68), comorbid MDD and anxiety (n = 88), panic disorder, and/or social anxiety disorder without comorbid MDD (n = 68) and healthy controls (n = 65). Volumetric magnetic resonance imaging was conducted for voxel-based morphometry analyses. We tested voxelwise for the effects of diagnosis, age at onset, and recurrence on gray matter density. Post hoc, we studied the effects of use of medication, illness severity, and sex. We demonstrated lower gray matter volumes of the rostral anterior cingulate gyrus extending into the dorsal anterior cingulate gyrus in MDD, comorbid MDD and anxiety, and anxiety disorders without comorbid MDD, independent of illness severity, sex, and medication use. Furthermore, we demonstrated reduced right lateral inferior frontal volumes in MDD and reduced left middle/superior temporal volume in anxiety disorders without comorbid MDD. Also, patients with onset of depression before 18 years of age showed lower volumes of the subgenual prefrontal cortex. Our findings indicate that reduced volume of the rostral-dorsal anterior cingulate gyrus is a generic effect in depression and anxiety disorders, independent of illness severity, medication use, and sex. This generic effect supports the notion of a shared etiology and may reflect a common symptom dimension related to altered emotion processing. Specific involvement of the inferior frontal cortex in MDD and lateral temporal cortex in anxiety disorders without comorbid MDD, on the other hand, may reflect disorder-specific symptom clusters. Early onset of depression is associated with a distinct neuroanatomical profile that may represent a vulnerability marker of depressive disorder.

Few studies examined characteristics of initial fearful spells (FS) or panic attacks (PA) and their relation to DSM-IV PA and panic disorder (PD). A community sample of adolescents and young adults (N=3021) was followed up in 4 waves (T0-T3) over up to 10 years. FS, PA, and PD were assessed at each wave using the DSM-IV/M-CIDI. Characteristics of the initial FS/PA including perceived reasons/triggers, appraisal, duration, and behavioral/emotional consequences of the initial FS/PA were retrospectively assessed at T1 and T2 in those reporting the experience of lifetime FS or PA at these waves (N=363). Multinomial logistic regressions adjusted for sex and age were used to reveal associations of initial FS/PA characteristics (aggregated data from T1 and T2) with PA only (N=88) and PD (N=62; lifetime incidences cumulated across assessment waves) (reference group: No PA/PD). Alcohol consumption, drugs/medication, and physical illness as perceived reasons for the initial FS/PA were associated with PA-only (OR 2.46-5.44), while feelings of depression, feelings of anxiety, and having always been anxious/nervous as perceived reasons for the initial FS/PA, appraising the initial FS/PA as terrible and long-term irritating/burdensome, subsequent feelings of depression, subsequent avoidance, and subsequent consumption of medication, alcohol, or drugs were associated with PD (OR 2.64-4.15). A longer duration until "feeling okay again" was associated with both PA-only (OR=1.29 per category) and PD (OR=1.63). Initial FS/PA characteristics were necessarily assessed retrospectively by self-report only. Thus, our data might be subject to recall/evaluation biases. Aggregated data were used and strictly prospective-longitudinal studies are necessary that replicate our findings. Assessing initial FS/PA characteristics might be useful to identify individuals at increased risk for more severe panic pathology. Copyright © 2014 Elsevier B.V. All rights reserved.

One of the hallmark features of major depressive disorder (MDD) is reduced reward anticipation. There have been mixed findings in the literature as to whether reward anticipation deficits in MDD are related to diminished mesolimbic activation and/or enhanced dorsal anterior cingulate activation (dACC). One of the reasons for these mixed findings is that these studies have typically not addressed the role of comorbid anxiety, a class of disorders which frequently co-occur with depression and have a common neurobiology. The aim of the current study was to examine group differences in neural responses to reward anticipation in 40 adults with either: (1) current MDD with no lifetime diagnosis of an anxiety disorder (MDD-only), (2) current MDD with comorbid panic disorder (MDD-PD), or (3) no lifetime diagnosis of psychopathology. All participants completed a passive slot machine task during a functional magnetic resonance imaging (fMRI) scan. Analyses indicated that there were no group differences in activation of mesolimbic reward regions; however, the MDD-only group exhibited greater dACC activation during the anticipation of rewards compared with the healthy controls and the comorbid MDD-PD group (who did not differ from each other). The sample size was small which limits generalizability. These findings provide preliminary support for the role of hyperactive dACC functioning in reduced reward anticipation in MDD. They also indicate that comorbid anxiety may alter the association between MDD and neural responding to reward anticipation. Copyright © 2014 Elsevier B.V. All rights reserved.

Previous estimates of the prevalence of anxiety disorders in late life vary greatly due to the lack of reliable diagnostic tools. This MentDis_ICF65+ study assessed 12-month prevalence rates of anxiety disorders and age- and gender-related differences in comorbidities, as well as impact on quality of life. The study used a cross-sectional multicenter survey. The study sample comprised 3,142 men and women aged 65 to 84 years, living in five European countries and Israel. Anxiety disorders were assessed using computer-assisted face-to-face interviews with an age-appropriate diagnostic interview (CIDI65+). The prevalence of anxiety disorders was 17.2%. Agoraphobia was the most frequent disorder (4.9%), followed by panic disorder (3.8%), animal phobia (3.5%), general anxiety disorder (3.1%), post-traumatic stress disorder (1.4%), social phobia (1.3%), and obsessive-compulsive disorder (0.8%). The prevalence rate of any anxiety disorder dropped by 40% to 47% in adults aged 75-84 years compared with those aged 65-74 years. Women were twice as likely to present with agoraphobia or general anxiety disorder as men. Only panic disorder and phobia were associated with comorbid major depression. The negative relationship with quality of life was limited to agoraphobia and generalized anxiety disorder. The age-appropriate CIDI65+ led to higher prevalence rates of anxiety disorders in the elderly, yet to weaker associations with comorbidities and impaired quality of life compared with previous studies.

The relationship between Panic Disorder (PD) and impulsivity is not well explored. The present investigation aims to compare impulsivity, measured by different rating tools, in PD patients vs. healthy controls and to explore the influence of co-morbid Cyclothymic Disorder (CD) on the relationship between PD and impulsivity. Sixty-four subjects with PD and 44 matched controls underwent a diagnostic and symptomatological evaluations by the Mini Neuropsychiatric Interview (M.I.N.I) Plus 5.0; the Bech-Rafaelsen Depression and Mania Scale (BRDMS), the State-Trait Anxiety Inventory (STAI), the Hypomania Check List (HCL-32) and the Clinical Global Impression (CGI); the Questionnaire for the Affective and Anxious Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Modified (TEMPS-M), the Separation Anxiety Sensitivity Index (SASI), the Interpersonal Sensitivity Symptoms Inventory (ISSI). Finally, psychometric and neurocognitive evaluations of impulsivity was carried out using the Barratt Impulsiveness Scale (BIS-11) and the Immediate and Delayed Memory Task (IMT/DMT). Subjects with PD were more impulsive than the controls in all the explored measures, reporting higher scores in symptomatological and temperamental scales. The comparison between PD patients with (Cyclo+) and without (Cyclo-) comorbid CD and controls showed that Cyclo+ are the most impulsive subjects in all the investigated measures and are characterized by the greatest symptomatological impairment, the highest scores in temperamental scales, and the highest levels of interpersonal sensitivity and separation anxiety. In our patients with PD, without lifetime comorbidity with major mood episodes, trait and state impulsivity may be related to the presence of comorbid cyclothymic mood instability.

Assessment of suicide plans is standard in acute psychiatric care, but there is a limited evidence base to guide this routine clinical practice. The purpose of this study was to investigate clinical correlates of suicide planning in depressed patients. 151 patients with major depressive disorder and a lifetime history of suicide attempt were studied. Subjects received a comprehensive evaluation including structured diagnostic interview for Axis I and II disorders, current symptoms, impulsivity, and systematic assessment of suicide planning prior to the most recent suicide attempt. Seriousness of suicide attempt planning correlated with lethality of suicidal acts. Comorbid anxiety disorder and anxiety correlated with less suicide planning. Specifically, this negative correlation was with comorbid panic disorder. Planning did not correlate with severity of depression or aggressive/impulsive traits. Cross-sectional design, retrospective recall of suicide planning data, limited applicability to completed suicide or other psychiatric disorders. In major depression, comorbid panic disorder appears protective against more carefully planned, higher lethality suicide attempts. Surprisingly, severity of depression and aggressive impulsive traits do not predict planning or lethality of suicide attempts. We have previously reported that anxiety severity protects against the probability of a suicide attempt and now extend that observation to show there is protection against lethality of a suicide attempt. Treatment of anxiety without directly treating major depression may place patients at greater risk of suicidal behavior.

The prevalence of panic disorder (PD) in the population is high and these patients have work impairment, high unemployment rates, seek medical treatment more frequently and have more hospitalizations than people without panic symptoms. Despite the availability of pharmacological, psychological and combined treatments, approximately one-third of all PD patients have persistent panic attacks and other PD symptoms after treatment. MEDLINE/Pubmed, CENTRAL, PsycINFO and Web of Science databases were searched for clinical trials in treatment-resistant PD. Only studies published between 1980 and 2015, in English, with human subjects, considered "journal articles" and clinical trial were included. We included trials recruiting only adult subjects with treatment-resistant PD, consistent with criteria from DSM-III to DSM5. We included all prospective experimental studies. Case, case series, retrospective studies or studies with <10 PD subjects were not included. Only 11 articles were included in this review. There were few quality studies, only two were randomized, controlled and double blind. Augmentation of the pharmacological treatment with cognitive-behavioral therapy demonstrated some short-term efficacy in treatment-resistant PD. There were also preliminary evidences of efficacy for monotherapy with reboxetine and olanzapine, and augmentation with pindolol, divalproex sodium, aripiprazole and olanzapine in short-term treatment.

The article describes the current state of scientific publications in the field of psychiatry in the Russian Federation. Issues of academic dissertations, lack of access to recent Russian language research in foreign databases, and recent reforms in the Ministry of Education and Science for overcoming these limitations are discussed in detail. Four exemplary dissertation studies published in Russian language are summarized. The first research examines the contribution of patient's verbal behavior to the reliable diagnosis of mild depression, identifying objective signs for distinguishing it from normal sadness; the mood component influenced the whole mental status and was represented in both structure and semantics of patients' speech. The second paper describes the course of panic disorder with agoraphobia, with the notable results that debut of panic disorder with full-blown panic attacks, often declines to a second accompanied with agoraphobia, which after several years gives way to limited symptom attacks and decreased agoraphobic avoidance. The third study describes the high prevalence of affective and anxiety disorders in patients with diabetes mellitus type 1 and 2, and the role of personality traits in adherence to treatment in patients with poor glucose control. The fourth project uses functional MRI for probing the features of neuronal resting-state networks in patients with temporal lobe epilepsy; the association with affective symptoms provides a model for investigating the pathophysiology of mood disorder.

To report a case of nightmares and sleep disorder associated with improper use of carvedilol, an alpha/beta-blocker, and to model the time course of receptor occupancy in this patient. A 41-year-old man with panic disorder had been treated with alprazolam 1.2 mg/d (3 times daily), carvedilol 10 mg/d (once in the morning), and etizolam 0.5 mg (for anxiety attack). Although the physical and psychological symptoms gradually improved, he reported nightmares and panic attacks. An interview revealed that he had been taking carvedilol 5 mg twice a day after lunch and dinner on his own initiative, in addition to the prescribed dosage. The patient was asked to take carvedilol 10 mg only after breakfast, as had been advised. Consequently, the sleep disorder and nightmares disappeared. We calculated the time courses of beta(2)-adrenoceptor binding occupancy in the central nervous system after oral administration of carvedilol with the ordinary and improper regimens by using pharmacokinetic/pharmacodynamic parameters obtained from the literature. Compared with the ordinary dose of carvedilol 10 mg once a day, the improper regimen (10 mg after breakfast followed by 5 mg after lunch and dinner) increases the beta(2)-adrenoceptor binding occupancy at night (2300) to as high as the mean beta(2)-adrenoceptor binding occupancy after an ordinary dose of propranolol. The sleep disorder and nightmares experienced by this patient had been induced by elevation of central beta(2)-adrenoceptor binding occupancy at night as the result of improper use of carvedilol.

2008-01-01

Background Panic disorder (PD) is one of the most common anxiety disorders seen in general practice, but provision of evidence-based cognitive-behavioural treatment (CBT) is rare. Many Australian GPs are now trained to deliver focused psychological strategies, but in practice this is time consuming and costly. Objective To evaluate the efficacy of an internet-based CBT intervention (Panic Online) for the treatment of PD supported by general practitioner (GP)-delivered therapeutic assistance. Design Panic Online supported by GP-delivered face-to-face therapy was compared to Panic Online supported by psychologist-delivered email therapy. Methods Sixty-five people with a primary diagnosis of PD (78% of whom also had agoraphobia) completed 12 weeks of therapy using Panic Online and therapeutic assistance with his/her GP (n = 34) or a clinical psychologist (n = 31). The mean duration of PD for participants allocated to these groups was 59 months and 58 months, respectively. Participants completed a clinical diagnostic interview delivered by a psychologist via telephone and questionnaires to assess panic-related symptoms, before and after treatment. Results The total attrition rate was 20%, with no group differences in attrition frequency. Both treatments led to significant improvements in panic attack frequency, depression, anxiety, stress, anxiety sensitivity and quality of life. There were no statistically significant differences in the two treatments on any of these measures, or in the frequency of participants with clinically significant PD at post assessment. Conclusions When provided with accessible online treatment protocols, GPs trained to deliver focused psychological strategies can achieve patient outcomes comparable to efficacious treatments delivered by clinical psychologists. The findings of this research provide a model for how GPs may be assisted to provide evidence-based mental healthcare successfully. PMID:22477844

Anxiety disorders: diagnosis and treatment.

PubMed

Jack, R A; Mathew, R J

1985-07-01

Pathologic anxiety, marked by inappropriate apprehension and/or fear, causes patients to seek help. Anxiety is associated with a wide variety of physical illnesses, and these must be initially considered when making a diagnosis. Similarly, anxiety associated with a wide variety of psychiatric syndromes must also be considered. Finally, the possibility of transient situational anxiety is ever present. Once it is determined that a primary anxiety disorder exists, then the presence or absence of phobias, panic attacks, and chronic "free-floating" anxiety will fully characterize the disorder. With an accurate diagnosis in hand, a multifaceted treatment approach can be designed. Effective treatments now exist for phobic and panic disorders, and more effective treatment for chronic generalized anxiety may be forthcoming.

Among Cambodian refugees with panic disorder (N = 208), we performed two factor analyses, one with the ASI, another with an Augmented ASI (consisting of the 16-item ASI supplemented with a 9-item addendum that assesses additional Cambodian concerns about anxiety-related sensations). The principal component analysis of the ASI yielded a 3-factor solution (I, "Weak Heart Concerns"; II, "Social Concerns"; III, "Control Concerns"); the Augmented ASI, a 4-factor solution: I, "Wind Attack Concerns"; II, "Weak Heart Concerns"; III, "Social Concerns"; and IV, "Control Concerns." The item clustering within the factor solution of both the ASI and Augmented ASI illustrates the role of cultural syndromes in generating fear of mental and bodily events.

Relatively little is known about psychological effects of environmental hazard disasters. This study examines the development of posttraumatic stress (PTS) and tendency to limited panic attack after a large chlorine spill in a community. In January 2005, a large chlorine spill occurred in Graniteville, SC. Acute injuries were quantified on an ordinal severity scale. Eight to ten months later, participating victims completed the Short Screening Scale for PTSD (n = 225) and the Holden Psychological Screening Inventory (HPSI) (n = 193) as part of a public health intervention. Forced expiratory volume in 1 s (FEV(1)) and forced vital capacity were likewise measured via spirometry. Two sets of univariate logistic regression models were fit to detect independent effects of each potential covariate and risk factor on PTS score and tendency to panic. A supplemental analysis examined whether poor lung function may be a confounder and/or effect modifier of the effect of acute injury on PTS score and panic. Of those who completed psychological screening, 36.9% exhibited PTS symptoms. FEV(1), acute injury, and the HPSI psychiatric subscale were independently associated with increased PTS score. Acute injury severity scale and female sex were associated with tendency to panic. Immediate acute injury severity and poor lung function later were independently associated with PTS symptomotology. The high prevalence of PTS and endorsement of tendency to panic within our sample show a need for mental health treatment after a chemical hazard disaster. Mental health personnel should be considerate of those with serious physical injuries.

Authors of this article focused on the analysis of the influence location of the fiber-optic sensor on the measurement and determination the heart rate of the human body. The sensor uses a Fiber Bragg Grating (FBG) and is encapsulated in the polymer polydimethylsiloxane (PDMS). The combination of fiber-optic technology and its encapsulation in a polymer PDMS allows the use of the sensor e.g. in magnetic resonance environments (MRI). Among currently solved doctors requirements belongs field focusing on the study of hyperventilation and panic attacks of patients during MRI examination due to their very frequent occurrence. Proposed FBG sensor can help doctors to predict (based on heart rate) hyperventilation and panic attacks of patients during MRI examinations. For the most accurate determination of the heart rate, it is necessary to know the influence location of the sensor on the human body. The sensor functionality and analysis of the sensor placement on the heart rate has been verified by a series of real experimental measurements of test subjects in laboratory environment.

2005-06-01

Studies suggest that vulnerability to panic attacks and panic disorder (PD) may be related to a deficient serotonin (5-HT) neurotransmission. In the present case-control study we investigated possible associations between PD phenotype and five candidate polymorphisms including 5-HT transporter (5-HTTLPR and VNTR), monoamine oxidase A (MAOA promoter region), tryptophan hydroxylase 1 (TPH1 218A/C) and 5-HT1B receptor (5-HT1BR 861G/C) genes. The study sample consisted of 158 patients with PD and 215 healthy control subjects. The analysis showed higher frequencies of LL genotype (p = 0.016) and L allele variant (p = 0.007) of 5-HTTLPR in the patients. No significant associations were observed between PD and other candidate gene polymorphisms. However, a higher frequency of longer allele genotypes of the MAOA promoter region was observed in female PD patients with agoraphobia than in female controls (p = 0.016). These findings indicate that genetic variants conceivably related to lower 5-HT neurotransmission may be involved in the development of PD.

Respiratory physiology and pathological anxiety.

PubMed

Gorman, J M; Uy, J

1987-11-01

There has been comparatively little attention paid to the respiratory derangements in anxiety disorders. Some authorities contend, however, that indices of respiratory function may be the best objective marker of anxiety state. Furthermore, an understanding of the ventilatory status of patients with anxiety disorder has shed light on the basic pathophysiology of abnormal anxiety. For example, it is now clear that patients with a wide variety of anxiety disorders hyperventilate both chronically and acutely. Therefore, we present an explanation of the physiological changes produced by hyperventilation. In order to further study ventilatory physiology in patients with anxiety disorder, our group and others have used the carbon dioxide challenge test. The data from these experiments suggest that patients with panic disorder are hypersensitive to carbon dioxide and that carbon dioxide inhalation induces panic attacks in susceptible patients. Hyperventilation appears to be a secondary, but pathophysiologically important, event in the generation of acute panic. The implications of work in respiratory physiology for clinical management of patients with anxiety disorder are discussed.

Self-reported anxiety, and potentially physiological response, to maintained inhalation of carbon dioxide (CO2) enriched air shows promise as a putative marker of panic reactivity and vulnerability. Temporal stability of response systems during low-dose, steady-state CO2 breathing challenge is lacking. Outcomes on multiple levels were measured two times, one week apart, in 93 individuals. Stability was highest during the CO2 breathing phase compared to pre-CO2 and recovery phases, with anxiety ratings, respiratory rate, skin conductance level, and heart rate demonstrating good to excellent temporal stability (ICCs ≥ 0.71). Cognitive symptoms tied to panic were somewhat less stable (ICC = 0.58) than physical symptoms (ICC = 0.74) during CO2 breathing. Escape/avoidance behaviors and DSM-5 panic attacks were not stable. Large effect sizes between task phases also were observed. Overall, results suggest good-excellent levels of temporal stability for multiple outcomes during respiratory stimulation via 7.5% CO2.

Background Prior studies on the depression-heart disease association have not usually used diagnostic measures of depression, nor taken other mental disorders into consideration. As a result, it is not clear whether the association between depression and heart disease onset reflects a specific association, or the comorbidity between depression and other mental disorders. Additionally, the relative magnitude of associations of a range of mental disorders with heart disease onset is unknown. Methods Face-to-face household surveys were conducted in 19 countries (n=52,095; person years=2,141,194). The Composite International Diagnostic Interview retrospectively assessed lifetime prevalence and age at onset of 16 DSM-IV mental disorders. Heart disease was indicated by self-report of physician’s diagnosis, or self-report of heart attack, together with their timing (year). Survival analyses estimated associations between first onset of mental disorders and subsequent heart disease onset. Results After comorbidity adjustment, depression, panic disorder, specific phobia, post-traumatic stress disorder and alcohol use disorders were associated with heart disease onset (ORs 1.3–1.6). Increasing number of mental disorders was associated with heart disease in a dose-response fashion. Mood disorders and alcohol abuse were more strongly associated with earlier onset than later onset heart disease. Associations did not vary by gender. Conclusions Depression, anxiety and alcohol use disorders were significantly associated with heart disease onset; depression was the weakest predictor. If confirmed in future prospective studies, the breadth of psychopathology’s links with heart disease onset has substantial clinical and public health implications. PMID:23993321

Quality of life impairment in generalized anxiety disorder, social phobia, and panic disorder.

Barrera, Terri L; Norton, Peter J

2009-12-01

Interest in the assessment of quality of life in the anxiety disorders is growing. The present study examined quality of life impairments in individuals with generalized anxiety disorder (GAD), social phobia, and panic disorder. Results showed that individuals with these disorders reported less satisfaction with their quality of life than non-anxious adults in the community. However, the degree of quality of life impairment is similar across these three disorders. Additionally, comorbid depression, but not anxiety, was found to negatively impact quality of life in these individuals. Finally, diagnostic symptom severity was not found to influence quality of life, indicating that subjective measures of quality of life offer unique information on the effects of anxiety disorders.

The current study assesses the relationship between presenting symptomatology of the self-labeled Hispanic popular diagnosis of ataques de nervios and the specific co-morbid psychiatric diagnoses. Hispanic subjects seeking treatment at an anxiety disorders clinic (n = 156) were assessed with a specially designed self-report instrument for both traditional ataque de nervios and panic symptoms, and with structured or semistructured psychiatric interviews for Axis-I disorders. This report focuses on 102 subjects with ataque de nervios who also met criteria for panic disorder, other anxiety disorders, or an affective disorder. Distinct ataque symptom patterns correlated with co-existing panic disorder, affective disorders, or other anxiety disorders. Individuals with both ataque and panic disorder reported the most asphyxia, fear of dying, and increased fear during their ataques. People with ataques who also met criteria for affective disorder reported the most anger, screaming, becoming aggressive, and breaking things during ataques. Ataque positive subjects with other anxiety disorders were less salient for both panic-like and emotional-anger symptoms. The findings suggest that (a) ataque de nervios is a popular label referring to several distinct patterns of loss of emotional control, (b) the type of loss of emotional control is influenced by the associated psychiatric disorder, and (c) ataque symptom patterns may be a useful clinical marker for detecting psychiatric disorders. Further study is needed to examine the relationship between ataque de nervios and psychiatric disorders, as well as the relationship to cultural, demographic, environmental, and personality factors.

Cognitive behavioral therapy (CBT) and pharmacotherapy are efficacious for the short-term treatment of panic disorder. Less is known about the efficacy of these therapies for individuals who do not respond fully to short-term CBT. The current trial is a second-step stratified randomized design comparing two treatment conditions-selective serotonin reuptake inhibitor (SSRI; paroxetine or citalopram; n = 34) and continued CBT (n = 24)-in a sample of individuals classified as treatment nonresponders to an initial course of CBT for panic disorder. Participants were randomized to 3 months of treatment and then followed for an additional 9 months. Only treatment responders after 3 months were maintained on the treatment until 12-month follow-up. Data analysis focused on panic disorder symptoms and achievement of response status across the first 3 months of treatment. Final follow-up data are presented descriptively. Participants in the SSRI condition showed significantly lower panic disorder symptoms as compared to continued CBT at 3 months. Results were similar when excluding individuals with comorbid major depression or analyzing the entire intent-to-treat sample. Group differences disappeared during 9-month naturalistic follow-up, although there was significant attrition and use of nonstudy therapies in both arms. These data suggest greater improvement in panic disorder symptoms when switching to SSRI after failure to fully respond to an initial course of CBT. Future studies should further investigate relapse following treatment discontinuation for nonresponders who became responders.

Background Major depression (MD) and anxiety disorders such as panic disorder (PD), agoraphobia (AG) and social phobia (SP) are heritable and highly comorbid. However, the relative importance of genetic and environmental aetiology of the covariation between these disorders, particularly the relationship between PD and AG is less clear. Methods The present study measured MD, PD and AG in a population sample of 5440 twin pairs and 1245 single twins, about 45% of whom were also scored for SP. Prevalences, within individual comorbidity and twin odds ratios for comorbidity are reported. A behavioural genetic analysis of the four disorders using the classical twin design was conducted. Results Odds ratios for MD, PD, AG, and SP in twins of individuals diagnosed with one of the four disorders were increased. Heritability estimates under a threshold-liability model for MD, PD, AG, and SP respectively were 0.33 (CI:0.30–0.42), 0.38 (CI:0.24–0.55), 0.48 (CI:0.37–0.65) of, and 0.39 (CI:0.16–0.65), with no evidence for any variance explained by the common environment shared by twins. We find that a common genetic factor explains a moderate proportion of variance in these four disorders. The genetic correlation between PD and AG was 0.83. Conclusion MD, PD, AG, and SP strongly co-aggregate within families and common genetic factors explain a moderate proportion of variance in these four disorders. The high genetic correlation between PD and AG and the increased odds ratio for PD and AG in siblings of those with AG without PD suggests a common genetic aetiology for PD and AG. PMID:19750555

Odds ratios for MD, PD, AG, and SP in twins of individuals diagnosed with one of the four disorders were increased. Heritability estimates under a threshold-liability model for MD, PD, AG, and SP respectively were .33 (CI: 0.30-0.42), .38 (CI: 0.24-0.55), .48 (CI: 0.37-0.65), and .39 (CI: 0.16-0.65), with no evidence for any variance explained by the common environment shared by twins. We find that a common genetic factor explains a moderate proportion of variance in these four disorders. The genetic correlation between PD and AG was .83. MD, PD, AG, and SP strongly co-aggregate within families and common genetic factors explain a moderate proportion of variance in these four disorders. The high genetic correlation between PD and AG and the increased odds ratio for PD and AG in siblings of those with AG without PD suggests a common genetic etiology for PD and AG.

The Multidimensional Anxiety Scale for Children (MASC) is a widely used self-report questionnaire for the assessment of anxiety symptoms in children and adolescents with well documented predictive validity of the total score and subscales in internalizing and mixed clinical samples. However, no data exist on the screening efficiency in an inpatient sample of adolescents. To examine the psychometric properties and screening efficiency of the MASC in a high comorbid inpatient sample. The current study used receiver operating characteristic (ROC) analyses to investigate the predictive value of the MASC total and subscale scores for the Schedule for Affective Disorders and Schizophrenia for School-age children-Present and Lifetime version (K-SADS-PL), DSM-IV diagnoses of generalized anxiety disorder (GAD), separation anxiety disorder (SAD) and social phobia (SoP) in a highly comorbid inpatient sample of adolescents (11-18 years). The MASC total score predicted any anxiety disorder (AD) and GAD moderately well. Physical symptoms predicted GAD moderately well. Social anxiety and separation anxiety/panic did not predict SoP or SAD, respectively. Physical symptoms and harm avoidance also predicted the presence of major depressive disorder. The findings support the utility of the MASC total score to predict the presence of any AD and GAD. However, the utility of the social anxiety and separation anxiety/panic subscales showed limited utility to predict the presence of SAD and SoP, respectively. The MASC has probably a more limited function in screening for AD among a highly comorbid inpatient sample of severely affected adolescents. Our results should be interpreted in the light of a small, mixed sample of inpatient adolescents.

To evaluate the prevalence and course of Axis I concurrent disorders in a population of patients who underwent cognitive-behavioural therapy (CBT) to treat their generalized anxiety disorder (GAD). This study is a secondary analysis combining patients from 3 treatment studies done at Université Laval. A total of 90 patients with a DSM-IV consistent GAD diagnosis received from 12 to 16 CBT sessions to treat GAD. Symptomatology was assessed at pretest, posttest, and 6 months after treatment, with the Anxiety Disorders Interview Schedule, a structured diagnostic interview. Seventy-three per cent of patients had both GAD and a concurrent diagnosis. The most common diagnoses were simple phobia, social phobia, panic disorder, and major depression. CBT applied to GAD decreases the number of concurrent diagnoses. A panic disorder or a greater number of concurrent diagnoses at pretest is associated with a less efficient treatment at follow-up 6 months later. Patients with GAD have a high comorbidity rate with other Axis I disorders, but these significantly decrease after a short CBT aimed at GAD. Implications for GAD treatment and mechanisms that might explain these findings are discussed.

Differential behavioral sensitivity to carbon dioxide (CO2) inhalation in rats

Winter, Andrew; Ahlbrand, Rebecca; Naik, Devanshi; Sah, Renu

2017-01-01

Inhalation of carbon dioxide (CO2) is frequently employed as a biological challenge to evoke intense fear and anxiety. In individuals with panic disorder, CO2 reliably evokes panic attacks. Sensitivity to CO2 is highly heterogeneous among individuals, and although a genetic component is implicated, underlying mechanisms are not clear. Preclinical models that can simulate differential responsivity to CO2 are therefore relevant. In the current study we investigated CO2-evoked behavioral responses in four different rat strains: Sprague-Dawley (SD), Wistar (W), Long Evans (LE) and Wistar-Kyoto, (WK) rats. We also assessed tryptophan hydroxylase 2 (TPH-2)-positive serotonergic neurons in anxiety/panic regulatory subdivisions of the dorsal raphe nucleus (DR), as well as dopamine β hydroxylase (DβH)-positive noradrenergic neurons in the locus coeruleus, implicated in central CO2-chemosensitivity. Behavioral responsivity to CO2 inhalation varied between strains. CO2-evoked immobility was significantly higher in LE and WK rats as compared with W and SD cohorts. Differences were also observed in CO2-evoked rearing and grooming behaviors. Exposure to CO2 did not produce conditioned behavioral responses upon re-exposure to CO2 context in any strain. Reduced TPH-2 positive cell counts were observed specifically in the panic-regulatory dorsal raphe ventrolateral (DRVL)-ventrolateral periaqueductal grey (VLPAG) subdivision in CO2-sensitive strains. Conversely, DβH positive cell counts within the LC were significantly higher in CO2-sensitive strains. Collectively, our data provide evidence for strain dependent, differential CO2-sensitivity and potential differences in monoaminergic systems regulating panic and anxiety. Comparative studies between CO2-vulnerable and resistant strains may facilitate the mechanistic understanding of differential CO2-sensitivity in the development of panic and anxiety disorders.

Interaction order and anxiety disorder: A 'Batesonian' heuristic of speaking patterns during psychotherapy.

PubMed

Streeck, Jürgen

2011-01-01

This paper describes speaking practices enacted by young female in-patients during psychotherapy sessions. The patients are in treatment for anxiety and panic disorders (social phobias). The practices involve prosodic, lexical and pragmatic aspects of utterance construction. An effect that they share is that the speaker's embodied presence in her talk and her epistemic commitment to it are reduced as the utterance progresses. The practices are interpreted in light of Bateson's interactional theory of character formation: as elements of a self-sustaining system Angst (anxiety). The study has grown out of an interdisciplinary effort to explore possible relationships between types of anxiety and the communicative and linguistic patterns by which patients describe panic attacks and other highly emotional experiences.

Pheochromocytoma is a rare tumor of the adrenal gland. It often presents with the classic triad of headache, palpitations and generalized sweating. Although not described as a typical symptom of pheochromocytoma, anxiety is the fourth most common symptom reported by patients suffering of pheochromocytoma. We report the case of a 64 year old man who had severe anxiety and panic disorder as presenting symptoms of pheochromocytoma. After 13 years of psychiatric follow-up, the patient was diagnosed with malignant pheochromocytoma. After surgical resection of his pheochromocytoma and his hepatic metastases, the major panic attacks completely disappeared, the anxiety symptoms improved significantly and the psychiatric medications were stopped except for a very low maintenance dose of venlafaxine. We found in our cohort of 160 patients with pheochromocytoma 2 others cases of apparently benign tumors with severe anxiety that resolved after pheochromocytoma resection. These cases highlight that pheochromocytoma should be included in the differential diagnosis of refractory anxiety disorder. Anxiety and panic disorder may be the main presenting symptoms of pheochromocytoma.The diagnosis of pheochromocytoma should be excluded in cases of long-term panic disorder refractory to medications since the anxiety may be secondary to a catecholamine-secreting tumor.Surgical treatment of pheochromocytoma leads to significant improvement of anxiety disorders.

Childhood separation anxiety disorder (SAD) is hypothesized to share etiologic roots with panic disorder. The aim of this study was to estimate the genetic and environmental sources of covariance between childhood SAD and adult onset panic attacks (AOPA), with the primary goal to determine whether these two phenotypes share a common genetic diathesis. Participants included parents and their monozygotic or dizygotic twins (n = 1,437 twin pairs) participating in the Virginia Twin Study of Adolescent Behavioral Development and those twins who later completed the Young Adult Follow-Up (YAFU). The Child and Adolescent Psychiatric Assessment was completed at three waves during childhood/adolescence followed by the Structured Clinical Interview for DSM-III-R at the YAFU. Two separate, bivariate Cholesky models were fit to childhood diagnoses of SAD and overanxious disorder (OAD), respectively, and their relation with AOPA; a trivariate Cholesky model also examined the collective influence of childhood SAD and OAD on AOPA. In the best-fitting bivariate model, the covariation between SAD and AOPA was accounted for by genetic and unique environmental factors only, with the genetic factor associated with childhood SAD explaining significant variance in AOPA. Environmental risk factors were not significantly shared between SAD and AOPA. By contrast, the genetic factor associated with childhood OAD did not contribute significantly to AOPA. Results of the trivariate Cholesky reaffirmed outcomes of bivariate models. These data indicate that childhood SAD and AOPA share a common genetic diathesis that is not observed for childhood OAD, strongly supporting the hypothesis of a specific genetic etiologic link between the two phenotypes. © 2012 Wiley Periodicals, Inc.

The aim of the present study was to investigate the involvement of N-methyl-d-aspartate (NMDA) and amino-3-hydroxy-5-methyl-isoxazole-4-proprionate (AMPA)/kainate receptors of the prelimbic (PL) division of the medial prefrontal cortex (MPFC) on the panic attack-like reactions evoked by γ-aminobutyric acid-A receptor blockade in the medial hypothalamus (MH). Rats were pretreated with NaCl 0.9%, LY235959 (NMDA receptor antagonist), and NBQX (AMPA/kainate receptor antagonist) in the PL at 3 different concentrations. Ten minutes later, the MH was treated with bicuculline, and the defensive responses were recorded for 10 min. The antagonism of NMDA receptors in the PL decreased the frequency and duration of all defensive behaviors evoked by the stimulation of the MH and reduced the innate fear-induced antinociception. However, the pretreatment of the PL cortex with NBQX was able to decrease only part of defensive responses and innate fear-induced antinociception. The present findings suggest that the NMDA-glutamatergic system of the PL is critically involved in panic-like responses and innate fear-induced antinociception and those AMPA/kainate receptors are also recruited during the elaboration of fear-induced antinociception and in panic attack-related response. The activation of the glutamatergic neurotransmission of PL division of the MPFC during the elaboration of oriented behavioral reactions elicited by the chemical stimulation of the MH recruits mainly NMDA receptors in comparison with AMPA/kainate receptors.

New segregation analysis of panic disorder

We performed simple segregation analyses of panic disorder using 126 families of probands with DSM-III-R panic disorder who were ascertained for a family study of anxiety disorders at an anxiety disorders research clinic. We present parameter estimates for dominant, recessive, and arbitrary single major locus models without sex effects, as well as for a nongenetic transmission model, and compare these models to each other and to models obtained by other investigators. We rejected the nongenetic transmission model when comparing it to the recessive model. Consistent with some previous reports, we find comparable support for dominant and recessive models, and inmore » both cases estimate nonzero phenocopy rates. The effect of restricting the analysis to families of probands without any lifetime history of comorbid major depression (MDD) was also examined. No notable differences in parameter estimates were found in that subsample, although the power of that analysis was low. Consistency between the findings in our sample and in another independently collected sample suggests the possibility of pooling such samples in the future in order to achieve the necessary power for more complex analyses. 32 refs., 4 tabs.« less

Delineating specific clinical phenotypes of anxiety disorders is a crucial step toward better classification and understanding of these conditions. The present study sought to identify differential aversive responses to predictable and unpredictable threat of shock in healthy comparisons and in non-medicated anxiety patients with and without a history of panic attacks (PAs). 143 adults (72 healthy controls; 71 patients with generalized anxiety disorder (GAD) or/and social anxiety disorder (SAD), 24 with and 47 without PAs) were exposed to three conditions: 1) predictable shocks signaled by a cue, 2) unpredictable shocks, and 3) no shock. Startle magnitude was used to assess aversive responses. Across disorders, a PA history was specifically associated with hypersensitivity to unpredictable threat. By disorder, SAD was associated with hypersensitivity to predictable threat, whereas GAD was associated with exaggerated baseline startle. These results identified three physiological patterns. The first is hypersensitivity to unpredictable threat in individuals with PAs. The second is hypersensitivity to predictable threat, which characterizes SAD. The third is enhanced baseline startle in GAD, which may reflect propensity for self-generated anxious thoughts in the absence of imminent danger. These results inform current thinking by linking specific clinical features to particular physiology profiles.

Anxiety sensitivity and auditory perception of heartbeat.

PubMed

Pollock, R A; Carter, A S; Amir, N; Marks, L E

2006-12-01

Anxiety sensitivity (AS) is the fear of sensations associated with autonomic arousal. AS has been associated with the development and maintenance of panic disorder. Given that panic patients often rate cardiac symptoms as the most fear-provoking feature of a panic attack, AS individuals may be especially responsive to cardiac stimuli. Consequently, we developed a signal-in-white-noise detection paradigm to examine the strategies that high and low AS individuals use to detect and discriminate normal and abnormal heartbeat sounds. Compared to low AS individuals, high AS individuals demonstrated a greater propensity to report the presence of normal, but not abnormal, heartbeat sounds. High and low AS individuals did not differ in their ability to perceive normal heartbeat sounds against a background of white noise; however, high AS individuals consistently demonstrated lower ability to discriminate abnormal heartbeats from background noise and between abnormal and normal heartbeats. AS was characterized by an elevated false alarm rate across all tasks. These results suggest that heartbeat sounds may be fear-relevant cues for AS individuals, and may affect their attention and perception in tasks involving threat signals.

Re-examining the differential familial liability of agoraphobia and panic disorder.

Knappe, Susanne; Beesdo-Baum, Katja; Nocon, Agnes; Wittchen, Hans-Ulrich

2012-11-01

Controversy surrounds the question of whether agoraphobia (AG) exists as an independent diagnostic entity apart from panic. In favor of this position, AG without panic disorder (PD) in parents was found being unrelated to offsprings' risk for AG or PD, albeit it may enhance the familial transmission of PD (Nocon et al., Depress Anxiety 2008;25:422-434). However, a recent behavioral genetic analysis (Mosing et al., Depress Anxiety 2009;26:1004-1011) found an increased risk for both PD and AG in siblings of those with AG without PD, casting doubt on whether AG exists independently of PD. Convincing evidence for either position notably requires considering also other anxiety disorders to establish the position of AG relative to the panic/anxiety spectrum. Familial transmission of panic attacks (PAs), PD, and AG was examined in a 10-year prospective-longitudinal community study of 3,021 adolescents and young adults including completed direct and indirect information on parental psychopathology. Standardized diagnostic assessments using the Munich-Composite International Diagnostic Interview allowed generating exclusive diagnostic groups independent from diagnostic hierarchy rules. Parental PD without AG was associated with an increased risk for PA and PD+AG, but not for PD without AG or AG without PD in offspring. Parental AG without PD was unrelated to the offsprings' risk for PA, exclusive PD or AG, or PD+AG. Findings were largely unaffected by adjustment for other offspring or parental anxiety disorders. Findings provide further evidence for the independence of AG apart from the PD spectrum. © 2012 Wiley Periodicals, Inc.

Transcranial Direct Current Stimulation for Treating Depression in a Patient With Right Hemispheric Dominance: A Case Study.

Shiozawa, Pedro; da Silva, Mailu Enokibara; Cordeiro, Quirino

2015-09-01

We report the case of a 66-year-old male patient with major depressive disorder for the last 6 months. The patient had been diagnosed with dyslexia during childhood and was left-handed. The intervention protocol consisted in 10 consecutive daily transcranial direct current stimulation sessions. However, after 5 days of stimulation, the patient presented with intensification of depressive symptoms and panic attacks. It was hypothetized that the intensification of symptoms may have been due to stimulation protocol itself. Considering the patient was left-handed and presented comorbidity with dyslexia, there was a plausible hypothesis of right hemispheric dominance. This was corroborated by the Edinburgh Handedness Scale. In fact, dyslexic patients present right hemisphere dominance more frequently. The patient also presented a single photon emission computed tomography with a hypoperfusion area over the left posterior parietal lobe. After the patients agreement, a 10-day experimental repetitive transcranial magnetic stimulation low-frequency protocol over the left dorsolateral prefrontal cortex was started to inhibit the area, which was hypothetically hyperactivated following the rationale of right dominance. The patient presented amelioration of depressive and anxious symptoms. Given the hemispheric reversal we show in the present case study, however, it seems that therapies that are beneficial to right-handers could be detrimental to left-handers.

Background Cyclic Vomiting Syndrome (CVS) is a disorder characterized by recurrent, stereotypic episodes of incapacitating nausea, vomiting and other symptoms, separated by intervals of comparative wellness. This report describes the clinical features, co-morbidities and problems encountered in management of 41 adult patients who met the diagnostic criteria for CVS. Methods This is a retrospective study of adults with CVS seen between 1994 and 2003. Follow-up data were obtained by mailed questionnaires. Results Age of onset ranged from 2 to 49 years. The duration of CVS at the time of consultation ranged from less than 1 year to 49 years. CVS episodes were stereotypic in respect of their hours of onset, symptomatology and length. Ninety-three percent of patients had recognizable prodromes. Half of the patients experienced a constellation of symptoms consisting of CVS episodes, migraine diathesis, inter-episodic dyspeptic nausea and a history of panic attacks. Deterioration in the course of CVS is indicated by coalescence of episodes in time. The prognosis of CVS is favorable in the majority of patients. Conclusion CVS is a disabling disorder affecting adults as well as children. Because its occurrence in adults is little known, patients experience delayed or mis-diagnosis and ineffectual, sometimes inappropriately invasive management. PMID:16368014

Recent attention has begun to be focused on the effects of disaster recovery work on nonrescue workers. The goal of this study was to assess the prevalence and predictors of posttraumatic stress disorder (PTSD) and related symptoms in a population of utility workers deployed to the World Trade Center (WTC) site in the aftermath of 9/11. Utility workers deployed to the WTC site were screened at their place of employment between 10 and 34 months following the WTC attacks, utilizing both structured interviews and self-report measures. PTSD symptoms were assessed by the CAPS and the PCL; co-morbid disorders were also assessed. 2,960 individuals with complete CAPS and PCL data were included in the analyses. Eight percent of participants had symptoms consistent with full PTSD, 9.3% with subthreshold PTSD, 6% with MDD, 3.5% with GAD, and 2.5% with panic disorder. Although risk factors included psychiatric and trauma history, 51% of individuals with probable PTSD had neither; subjective perception of threat to one's life was the best predictor of probable PTSD. Extent of exposure predicted 89% of PTSD cases in those without a psychiatric or trauma history, but only 67% of cases among those with both. Nonrescue workers deployed to a disaster site are at risk for PTSD and depression. Extent of exposure affected the most vulnerable workers differently than the least vulnerable ones. These results suggest that the relationship among predictors of PTSD may be different for different vulnerability groups, and underscore the importance of screening, education, and prevention programs for disaster workers. © 2010 Wiley-Liss, Inc.

The dorsomedial hypothalamus (DMH) and the dorsal periaqueductal gray (DPAG) have been implicated in the genesis and regulation of panic-related defensive behaviors, such as escape. Previous results point to an interaction between serotonergic and opioidergic systems within the DPAG to inhibit escape, involving µ-opioid and 5-HT1A receptors (5-HT1AR). In the present study we explore this interaction in the DMH, using escape elicited by electrical stimulation of this area as a panic attack index. The obtained results show that intra-DMH administration of the non-selective opioid receptor antagonist naloxone (0.5 nmol) prevented the panicolytic-like effect of a local injection of serotonin (20 nmol). Pretreatment with the selective μ-opioid receptor (MOR) antagonist CTOP (1 nmol) blocked the panicolytic-like effect of the 5-HT1AR agonist 8-OHDPAT (8 nmol). Intra-DMH injection of the selective MOR agonist DAMGO (0.3 nmol) also inhibited escape behavior, and a previous injection of the 5-HT1AR antagonist WAY-100635 (0.37 nmol) counteracted this panicolytic-like effect. These results offer the first evidence that serotonergic and opioidergic systems work together within the DMH to inhibit panic-like behavior through an interaction between µ-opioid and 5-HT1A receptors, as previously described in the DPAG.

Is panic disorder a disorder of physical fitness? A heuristic proposal.

PubMed

Perna, Giampaolo; Caldirola, Daniela

2018-01-01

Currently, panic disorder (PD) is considered a mental disorder based on the assumptions that panic attacks (PAs) are "false alarms" that arise from abnormally sensitive defense systems in the central nervous system and that PD is treated with therapies specifically acting on anxiety or fear mechanisms. This article aims to propose an alternative perspective based on the results of some experimental studies. Our heuristic proposal suggests not only that PD may be a mental disorder but also that patients with PD have real abnormal body functioning, mainly involving cardiorespiratory and balance systems, leading to a decline in global physical fitness. PAs, as well as physical symptoms or discomfort in some environmental situations, may be "real alarms" signaling that the adaptability resources of an organism are insufficient to respond appropriately to some internal or external changes, thus representing the transient conscious awareness of an imbalance in body functioning. The antipanic properties of several modern treatments for PD may include their beneficial effects on body functions. Although anxiety or fear mechanisms are evidently involved in PD, we hypothesize that a reduction of physical fitness is the "primum movens" of PD, while anxiety or fear is induced and sustained by repeated signals of impaired body functioning. We propose considering panic in a broader perspective that offers a central role to the body and to contemplate the possible role of somatic treatments in PD.

Various studies have assessed autonomic and respiratory underpinnings of panic attacks, yet the psychophysiological functioning of panic disorder (PD) patients has rarely been examined under naturalistic conditions at times when acute attacks were not reported. We hypothesized that emotional activation in daily life causes physiologically demonstrable deviations from efficient metabolic regulation in PD patients. Metabolic coupling was estimated as within-individual correlations between heart rate (HR) and indices of metabolic activity, i.e., physical activity (measured by 3-axial accelerometry, Acc), and minute ventilation (Vm, measured by calibrated inductive plethysmography, as proxy for oxygen consumption). A total of 565 daytime hours were recorded in 19 PD patients and 20 healthy controls (HC). Pairwise cross-correlations of minute-by-minute averages of these metabolic indices were calculated for each participant and then correlated with several indices of self-reported anxiety. Ambulatory HR was elevated in PD (p = .05, d = 0.67). Patients showed reduced HR-Acc (p < .006, d = 0.97) and HR-Vm coupling (p < .009, d = 0.91). Combining Vm and Acc to predict HR showed the strongest group separation (p < .002, d = 1.07). Discriminant analyses, based on the combination of Vm and Acc to predict HR, classified 77% of all participants correctly. In PD, HR-Acc coupling was inversely related to trait anxiety sensitivity, as well as tonic and phasic daytime anxiety. The novel method that was used demonstrates that anxiety in PD may reduce efficient long-term metabolic coupling. Metabolic decoupling may serve as physiological characteristic of PD and might aid diagnostics for PD and other anxiety disorders. This measure deserves further study in research on health consequences of anxiety and psychosocial stress. Copyright © 2015 Elsevier Ltd. All rights reserved.

Validity of the adolescent version of the World Health Organization Composite International Diagnostic Interview (CIDI) Version 3.0, a fully-structured research diagnostic interview designed to be used by trained lay interviewers, is assessed in comparison to independent clinical diagnoses based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). This assessment is carried out in the clinical reappraisal sub-sample (n = 347) of the US National Comorbidity Survey Adolescent Supplement (NCS-A), a large (n = 10,148) community epidemiological survey of the prevalence and correlates of adolescent mental disorders in the US. The diagnoses considered are panic disorder and phobic disorders (social phobia, specific phobia, agoraphobia). CIDI diagnoses are found to have good concordance with K-SADS diagnoses (AUC = .81–.94), although the CIDI diagnoses are consistency somewhat higher than the K-SADS diagnoses. Data are also presented on criterion-level concordance in an effort to pinpoint CIDI question series that might be improved in future modifications of the instrument. Finally, data are presented on the factor structure of the fears associated with social phobia, the only disorder in this series where substantial controversy exists about disorder subtypes.

Background Anxiety disorders are commonly comorbid with bipolar disorder (BP) and may worsen course of illness, but differential impact of specific anxiety disorders in men and women remains unknown. Methods We measured the impact of comorbid panic disorder (PD), social phobia, specific phobia, and obsessive-compulsive disorder (OCD) in 460 women and 276 men with Bipolar I Disorder (BPI) or schizoaffective disorder, bipolar type from the National Institute of Mental Health Bipolar Genetics Initiative. We compared clinical characteristics in BP with and without each anxiety disorder in men and women separately correcting for family relatedness. Results Comorbid PD, OCD, and specific phobia were more common in women with BP than men. Comorbid social phobia correlated with increased risk of alcohol abuse in BP women, but not men. Women with comorbid PD attended fewer years of school. Comorbidity with OCD was associated with earlier age at the onset of BP for both genders. Comorbid PD, OCD, and specific phobia were associated with more antidepressant trials in BP, across both genders, compared to BP patients without these anxiety disorders. Conclusion In BP, comorbid anxiety disorders are associated with increased risk for functional impairment, and women had differently associated risks than men. Clinicians should be aware of an increased risk for comorbid PD, OCD, and specific phobia in women with BP, and an increased risk of alcohol abuse in women with BD and comorbid social phobia.

2012-02-01

The age of the first episode of illness in Bipolar Disorder has been shown to be an important predictor of outcome with early onset, particularly onset before puberty, associated with greater comorbidity, a poorer quality of life and greatest impairment in functioning. Baseline data from a psychotherapy study was used to examine the prevalence of other comorbid psychiatric conditions and the impact of onset at an early age on both self harming behaviour and suicide attempts in young people with Bipolar Disorder. This study of 100 adolescents and young adults (aged 15-36 years) with Bipolar Disorder showed that comorbid conditions were very common, even at the start of their bipolar illness. Comorbidity increased as the age of onset decreased with very early onset (<13 years) patients bearing the greatest burden of disease. Greater comorbidity also significantly increased the risk of having self harmed and attempted suicide with high lethal intent. Self harming behaviour was predicted by having a lifetime diagnoses of Borderline Personality Disorder and Panic Disorder along with an early age of onset of Bipolar Disorder. In contrast, previous suicide attempts were predicted by greater comorbidity and not by very early (<13 years) age of onset. Copyright © 2011 Elsevier B.V. All rights reserved.

This study aimed to determine if current comorbid psychiatric disorders differ in adults with cocaine use disorder, other stimulant (primarily methamphetamine) use disorder, or both, and identify demographic and clinical characteristics in those with increasing numbers of comorbid disorders. Baseline data from a randomized controlled trial beginning in residential settings (N=302) was used. Mood disorders were present in 33.6%, and anxiety disorders in 29.6%, with no differences among stimulant use disorder groups. Panic disorder was more frequently present with other stimulant use disorder. Those with two or more comorbid psychiatric disorders were more often female, White, had more symptoms of depression, greater propensity and risk for suicidal behavior, lower functioning in psychiatric and family domains, lower quality of life, more symptoms with stimulant abstinence and greater likelihood of marijuana dependence. Those with one or more comorbid disorders had more medical disorder burden, lower cognitive and physical functioning, greater pain, and higher rates of other drug dependence. With current comorbid psychiatric disorders, the morbidity of stimulant use disorders increases. Use of validated assessments near treatment entry, and a treatment plan targeting not only substance use and comorbid psychiatric disorders, but functional impairments, medical disorder burden and pain, may be useful.

Traumatized Cambodian refugees with PTSD often complain of khyâl attacks. The current study investigates khyâl attacks from multiple perspectives and examines the validity of a model of how khyâl attacks are generated. The study found that khyâl attacks had commonly been experienced in the previous 4 weeks and that their severity was strongly correlated with the severity of PTSD (PTSD Checklist). It was found that khyâl attacks were triggered by various processes--such as worry, trauma recall, standing up, going to a mall--and that khyâl attacks almost always met panic attack criteria. It was also found that during a khyâl attack there was great fear that death might occur from bodily dysfunction. It was likewise found that a complex nosology of khyâl attacks exists that rates the attacks on a scale of severity, that the severity determines how the khyâl attacks should be treated and that those treatments are often complex. As illustrated by the article, khyâl attacks constitute a key aspect of trauma ontology in this group, a culturally specific experiencing of anxiety and trauma-related disorder. The article also contributes to the study of trauma somatics, that is, to the study of how trauma results in specific symptoms in a specific cultural context, showing that a key part of the trauma-somatic reticulum is often a cultural syndrome.

Depression and anxiety in patients with cardiac disease are common and independently associated with morbidity and mortality. We aimed to explore the use of a 3-step approach to identify inpatients with cardiac disease with depression, generalized anxiety disorder (GAD), or panic disorder; understand the predictive value of individual screening items in identifying these disorders; and assess the relative prevalence of these disorders in this cohort. To identify depression and anxiety disorders in inpatients with cardiac disease as part of a care management trial, an iterative 3-step screening procedure was used. This included an existing 4-item (Coping Screen) tool in nursing data sets, a 5-item screen for positive Coping Screen patients (Patient Health Questionnaire-2 [PHQ-2], GAD-2, and an item about panic attacks), and a diagnostic evaluation using PHQ-9 and the Primary Care Evaluation of Mental Disorders anxiety disorder modules. Overall, 6210 inpatients received the Coping Screen, 581 completed portions of all 3 evaluation steps, and 210 received a diagnosis (143 depression, 129 GAD, 30 panic disorder). Controlling for age, sex, and the other screening items, PHQ-2 items independently predicted depression (little interest/pleasure: odds ratio [OR]=6.65, P<0.001; depression: OR=5.24, P=0.001), GAD-2 items predicted GAD (anxious: OR=4.09, P=0.003; unable to control worrying: OR=10.46, P<0.001), and the panic item predicted panic disorder (OR=49.61, P<0.001). GAD was nearly as prevalent as depression in this cohort, and GAD-2 was an effective screening tool; however, panic disorder was rare. These results support the use of 2-step screening for depression and GAD beginning with a 4-item scale (GAD-2 plus PHQ-2). Unique Identifier: NCT01201967.

Improved statistical analysis of moclobemide dose effects on panic disorder treatment.

PubMed

Ross, Donald C; Klein, Donald F; Uhlenhuth, E H

2010-04-01

Clinical trials with several measurement occasions are frequently analyzed using only the last available observation as the dependent variable [last observation carried forward (LOCF)]. This ignores intermediate observations. We reanalyze, with complete data methods, a clinical trial previously reported using LOCF, comparing placebo and five dosage levels of moclobemide in the treatment of outpatients with panic disorder to illustrate the superiority of methods using repeated observations. We initially analyzed unprovoked and situational, major and minor attacks as the four dependent variables, by repeated measures maximum likelihood methods. The model included parameters for linear and curvilinear time trends and regression of measures during treatment on baseline measures. Significance tests using this method take into account the structure of the error covariance matrix. This makes the sphericity assumption irrelevant. Missingness is assumed to be unrelated to eventual outcome and the residuals are assumed to have a multivariate normal distribution. No differential treatment effects for limited attacks were found. Since similar results were obtained for both types of major attack, data for the two types of major attack were combined. Overall downward linear and negatively accelerated downward curvilinear time trends were found. There were highly significant treatment differences in the regression slopes of scores during treatment on baseline observations. For major attacks, all treatment groups improved over time. The flatter regression slopes, obtained with higher doses, indicated that higher doses result in uniformly lower attack rates regardless of initial severity. Lower doses do not lower the attack rate of severely ill patients to those achieved in the less severely ill. The clinical implication is that more severe patients require higher doses to attain best benefit. Further, the significance levels obtained by LOCF analyses were only in the 0.05-0.01 range, while significance levels of <0.00001 were obtained by these repeated measures analyses indicating increased power. The greater sensitivity to treatment effect of this complete data method is illustrated. To increase power, it is often recommended to increase sample size. However, this is often impractical since a major proportion of the cost per subject is due to the initial evaluation. Increasing the number of repeated observations increases power economically and also allows detailed longitudinal trajectory analyses.

Gastrointestinal-focused panic attacks among Cambodian refugees: associated psychopathology, flashbacks, and catastrophic cognitions.

2007-01-01

Among Cambodian refugees attending a psychiatric clinic, we assessed psychopathology associated with gastrointestinal panic (GIP), and investigated possible causal mechanisms, including "fear of fear" and GIP-associated flashbacks and catastrophic cognitions. GIP (n=46) patients had greater psychopathology (Clinician-Administered PTSD Scale [CAPS] and Symptom Checklist-90-R [SCL]) and "fear of fear" (Anxiety Sensitivity Index [ASI]) than did non-GIP patients (n=84). Logistic regression revealed that general psychopathology (SCL; odds ratio=4.1) and fear of anxiety-related sensations (ASI; odds ratio=2.4) predicted the presence of GIP. Among GIP patients, a hierarchical regression revealed that GIP-associated trauma recall and catastrophic cognitions explained variance in GIP severity beyond a measure of general psychopathology (SCL). A mediational analysis indicated that SCL's effect on GIP severity was mediated by GIP-associated flashbacks and catastrophic cognitions.

Involvement of prelimbic medial prefrontal cortex in panic-like elaborated defensive behaviour and innate fear-induced antinociception elicited by GABAA receptor blockade in the dorsomedial and ventromedial hypothalamic nuclei: role of the endocannabinoid CB1 receptor.

It has been shown that GABAA receptor blockade in the dorsomedial and ventromedial hypothalamic nuclei (DMH and VMH, respectively) induces elaborated defensive behavioural responses accompanied by antinociception, which has been utilized as an experimental model of panic attack. Furthermore, the prelimbic (PL) division of the medial prefrontal cortex (MPFC) has been related to emotional reactions and the processing of nociceptive information. The aim of the present study was to investigate the possible involvement of the PL cortex and the participation of local cannabinoid CB1 receptors in the elaboration of panic-like reactions and in innate fear-induced antinociception. Elaborated fear-induced responses were analysed during a 10-min period in an open-field test arena. Microinjection of the GABAA receptor antagonist bicuculline into the DMH/VMH evoked panic-like behaviour and fear-induced antinociception, which was decreased by microinjection of the non-selective synaptic contact blocker cobalt chloride in the PL cortex. Moreover, microinjection of AM251 (25, 100 or 400 pmol), an endocannabinoid CB1 receptor antagonist, into the PL cortex also attenuated the defensive behavioural responses and the antinociception that follows innate fear behaviour elaborated by DMH/VMH. These data suggest that the PL cortex plays an important role in the organization of elaborated forward escape behaviour and that this cortical area is also involved in the elaboration of innate fear-induced antinociception. Additionally, CB1 receptors in the PL cortex modulate both panic-like behaviours and fear-induced antinociception elicited by disinhibition of the DMH/VMH through microinjection of bicuculline.

A recent genome-wide association study in patients with panic disorder (PD) identified a risk haplotype consisting of two single-nucleotide polymorphisms (SNPs) (rs7309727 and rs11060369) located in intron 3 of TMEM132D to be associated with PD in three independent samples. Now we report a subsequent confirmation study using five additional PD case–control samples (n=1670 cases and n=2266 controls) assembled as part of the Panic Disorder International Consortium (PanIC) study for a total of 2678 cases and 3262 controls in the analysis. In the new independent samples of European ancestry (EA), the association of rs7309727 and the risk haplotype rs7309727–rs11060369 was, indeed, replicated, with the strongest signal coming from patients with primary PD, that is, patients without major psychiatric comorbidities (n=1038 cases and n=2411 controls). This finding was paralleled by the results of the meta-analysis across all samples, in which the risk haplotype and rs7309727 reached P-levels of P=1.4e−8 and P=1.1e−8, respectively, when restricting the samples to individuals of EA with primary PD. In the Japanese sample no associations with PD could be found. The present results support the initial finding that TMEM132D gene contributes to genetic susceptibility for PD in individuals of EA. Our results also indicate that patient ascertainment and genetic background could be important sources of heterogeneity modifying this association signal in different populations. PMID:22948381

It is argued that fear of fear, or phobophobia, can be an important maintaining factor in cases of seemingly free-floating anxiety with periodic panic attacks and that effective treatment consists of exposure to the feared neurovegetative sensations. The case history presented suggests that inhalation of CO2-O2 mixtures induces the phobic interoceptive sensations and that it can be used in the exposure treatment of phobophobia.

Panic disorder with agoraphobia (PDA) and generalized anxiety disorder (GAD) are impairing and costly disorders that are often misdiagnosed and left untreated despite multiple consultations. These disorders frequently co-occur, but little is known about the costs associated with their comorbidity and the impact of cognitive-behavioral therapy (CBT) on cost reduction. The first objective of this study was to assess the mental health-related costs associated with the specific concomitance of PDA and GAD. The second aim was to determine whether there is a reduction in direct and indirect mental health-related costs following conventional CBT for the primary disorder only (PDA or GAD) or combined CBT adapted to the comorbidity (PDA and GAD). A total of 123 participants with a double diagnosis of PDA and GAD participated in this study. Direct and indirect mental health-related costs were assessed and calculated from a societal perspective at the pre-test, the post-test, and the three-month, six-month and one-year follow-ups. At the pre-test, PDA-GAD comorbidity was found to generate a mean total cost of CADUSD 2,000.48 (SD = USD 2,069.62) per participant over a three-month period. The indirect costs were much higher than the direct costs. Both treatment modalities led to significant and similar decreases in all cost categories from the pre-test to the post-test. This reduction was maintained until the one-year follow-up. Methodological choices may have underestimated cost evaluations. Nonetheless, this study supports the cost offset effects of both conventional CBT for primary PDA or GAD and combined CBT for PDA-GAD comorbidity. Treatment of comorbid and costly disorders with evidence-based treatments such as CBT may lead to considerable economic benefits for society. Considering the limited resources of healthcare systems, it is important to make choices that will lead to better accessibility of quality services. The application of CBT for PDA, GAD or both disorders and training mental health professionals in this therapeutic approach should be encouraged. Additionally, it would be favorable for insurance plans to reimburse employees for expenses associated with psychological treatment for anxiety disorders. In addition to symptom reduction, it would be of great pertinence to explore which factors can contribute to reducing direct and indirect mental health-related costs.

Panic disorder (PD) patients are constantly concerned about future panic attacks and exhibit general hypersensitivity to unpredictable threat. We aimed to reveal phasic and sustained brain responses and functional connectivity of the amygdala and the bed nucleus of the stria terminalis (BNST) during threat anticipation in PD. Using functional magnetic resonance imaging (fMRI), we investigated 17 PD patients and 19 healthy controls (HC) during anticipation of temporally unpredictable aversive and neutral sounds. We used a phasic and sustained analysis model to disentangle temporally dissociable brain activations. PD patients compared with HC showed phasic amygdala and sustained BNST responses during anticipation of aversive v. neutral stimuli. Furthermore, increased phasic activation was observed in anterior cingulate cortex (ACC), insula and prefrontal cortex (PFC). Insula and PFC also showed sustained activation. Functional connectivity analyses revealed partly distinct phasic and sustained networks. We demonstrate a role for the BNST during unpredictable threat anticipation in PD and provide first evidence for dissociation between phasic amygdala and sustained BNST activation and their functional connectivity. In line with a hypersensitivity to uncertainty in PD, our results suggest time-dependent involvement of brain regions related to fear and anxiety.

Framing Samuel See: the discursive detritus of the moral panic over the "double epidemic" of methamphetamines and HIV among gay men.

2016-02-01

After being arrested for violating a restraining order against his husband, on November 24, 2013, Yale professor Samuel See died while in lockup at the Union Avenue Detention Center in New Haven, Connecticut. The death received media attention around the world, with readers arguing online about whether See's death was caused by police misconduct, as his friends and colleagues charged in interviews and during a well-publicised march and protest. When an autopsy revealed that he had died from a methamphetamine-induced heart attack, online commentary changed dramatically, with See's many supporters rhetorically abandoning him and others describing him as a stereotype of the gay meth addict who deserved his fate. In this article, I argue that this shift in the interpretation and meaning of See's death can be traced to the discursive structures left by the moral panic about crystal meth in the United States (1996-2008), which comprised within it a secondary moral panic about crystal meth in the gay community and its connection to the spread of HIV and a possible super-strain (2005-2008).

The death received media attention around the world, with readers arguing online about whether See’s death was caused by police misconduct, as his friends and colleagues charged in interviews and during a well-publicised march and protest. When an autopsy revealed that he had died from a methamphetamine-induced heart attack, online commentary changed dramatically, with See’s many supporters rhetorically abandoning him and others describing him as a stereotype of the gay meth addict who deserved his fate. In this article, I argue that this shift in the interpretation and meaning of See’s death can be traced to the discursive structures left by the moral panic about crystal meth in the United States (1996–2008), which comprised within it a secondary moral panic about crystal meth in the gay community and its connection to the spread of HIV and a possible super-strain (2005–2008).

Betaxolol in anxiety disorders.

PubMed

Swartz, C M

1998-03-01

Betaxolol, a long-acting beta-adrenergic blocker that enters the central nervous system, was examined for therapeutic effects on the persistent anxiety of anxiety disorders. Prior studies of beta-blockers examined only agents that were short-acting or did not enter the brain. Betaxolol was administered to 31 patients in open trials. Of 13 outpatients, 11 had generalized anxiety disorder (GAD) and 2 had adjustment disorder with anxiety. Five with GAD had concurrent panic disorder. Of 18 inpatients, 16 had GAD and 2 had adjustment disorder with anxiety. Betaxolol doses were increased until the patient responded or declined further dosage. Severity was rated on a 4-point global scale. Before betaxolol, all were moderately or severely ill. In all patients with panic disorder panic attacks stopped within 2 days (p<0.001). Anxiety decreased to no more than marginally ill in 85% of outpatients (p<0.0001) and all inpatients (p<0.0001). Betaxolol doses were usually 5 mg once or twice daily; four inpatients took 10 to 20 mg twice daily. In sum, betaxolol administration was rapidly followed by improvements that were easily noticed by the doctor, even in patients with longstanding anxiety and obsessive-compulsive personality disorder. Preliminary observations in posttraumatic stress disorder are similar.

Based on the results of a randomized controlled trial, we examined a model of the mechanisms of efficacy of culturally adapted cognitive-behavior therapy (CBT) for Cambodian refugees with pharmacology-resistant posttraumatic stress disorder (PTSD) and comordid orthostatic panic attacks (PAs). Twelve patients were in the initial treatment condition, 12 in the delayed treatment condition. The patients randomized to CBT had much greater improvement than patients in the waitlist condition on all psychometric measures and on one physiological measure-the systolic blood pressure response to orthostasis (d = 1.31)-as evaluated by repeated-measures MANOVA and planned contrasts. After receiving CBT, the Delayed Treatment Group improved on all measures, including the systolic blood pressure response to orthostasis. The CBT treatment's reduction of PTSD severity was significantly mediated by improvement in orthostatic panic and emotion regulation ability. The current study supports our model of the generation of PTSD in the Cambodian population, and suggests a key role of decreased vagal tone in the generation of orthostatic panic and PTSD in this population. It also suggests that vagal tone is involved in emotion regulation, and that both vagal tone and emotion regulation improve across treatment.

Prolonged Exposure Therapy and Irritable Bowel Syndrome: A Case Study Examining the Impact of a Trauma-Focused Treatment on a Physical Condition

Previous research has shown that psychological treatments, particularly those employing cognitive techniques, are particularly effective in the treatment of irritable bowel syndrome (IBS). It is presumed that these psychological interventions are effective at ameliorating the IBS by treating an underlying psychological disorder (often an anxiety disorder), which may be contributing to the autonomic reactivity. This case study examined the change in the physical symptoms of IBS for a patient seeking treatment for rape-related PTSD with comorbid conditions of major depression and panic. At posttreatment, the patient no longer met criteria for PTSD, major depression, or panic. In addition, her primary symptom of IBS, diarrhea frequency, was significantly improved. These findings were maintained at 3 and 9 months posttreatment. Implications for the assessment and treatment of IBS patients with PTSD are discussed. PMID:21179387

Anxiety disorders and drug dependence: evidence on sequence and specificity among adults.

PubMed

Goodwin, Renee D; Stein, Dan J

2013-04-01

The goal of this study was to investigate the relation between specific anxiety disorders and substance dependence, adjusting for potentially confounding demographic factors (e.g. sex) and comorbidity (e.g. alcohol dependence, major depression), among adults in the USA. Data were drawn from the National Comorbidity Survey (NCS), a nationally representative population sample of the US adult population aged 15-54. The temporal sequence of onset of anxiety and substance dependence disorders was examined. Substance dependence temporally precedes several anxiety disorders, particularly panic disorder. Specifically, a history of past substance dependence predicts current panic disorder (odds ratio [OR] =2.62, 95% confidence interval [CI] =1.29, 5.32), social phobia (OR=1.7, 95%CI=1.12, 2.41), and agoraphobia (OR=1.78, 95%CI=1.08, 2.94). Conversely, in more than 50% of substance abuse disorder cases, in nearly 40% of post-traumatic stress disorder (PTSD) cases, and in nearly 30% of generalized anxiety disorder (GAD) cases, the anxiety disorder has first onset. Similarly, a lifetime history of social phobia, PTSD, or GAD significantly predicts lifetime substance dependence (OR=1.51 for social phobia, 2.06 for PTSD, 1.45 for GAD). For any particular anxiety disorder, a diagnosis of substance abuse can occur prior to or subsequent to an anxiety disorder. Nevertheless, there is also evidence for the specificity of some associations between anxiety and substance dependence disorders; these are independent of the effects of sex and other comorbid disorders, may be causal in nature, and deserve particular attention in clinical settings. The possibility that within a particular anxiety disorder there are a variety of mechanisms of association with various substances should be addressed in future work. © 2013 The Authors.

Overlap of symptom domains of separation anxiety disorder in adulthood with panic disorder-agoraphobia.

PubMed

Silove, Derrick; Marnane, Claire

2013-01-01

There is a need to explain the high level of comorbidity between separation anxiety disorder (SAD) in adulthood and panic disorder with agoraphobia (Pd-Ag). One possibility is that inadequate specification of symptom domains and/or diagnostic questions accounts for some of the comorbidity. The present anxiety clinic study examined responses of adult patients (n = 646) with SAD and/or Pd-Ag on eight symptom domains based on a previous factor analysis of a commonly used separation anxiety measure, the ASA-27, as well as on the Anxiety Sensitivity Index. We also examined questionnaire items that did not load on the factor structure. All separation anxiety domains distinguished strongly between SAD and Pd-Ag. Comparisons across three groups (SAD alone, Pd-Ag alone and comorbid SAD/Pd-Ag) revealed that two symptom domains (anxiety about embarking on trips, and sleep disturbances) showed some overlap between Pd-Ag and SAD. Two of the items of the ASA-27 that did not load with other items in the factor analysis also showed overlap with Pd-Ag, with both referring to anxieties about leaving home. Patients with SAD (with or without Pd-Ag) returned higher scores on anxiety sensitivity than those with Pd-Ag alone. The findings support the distinctiveness of the construct of SAD and the capacity of the ASA-27 to discriminate between that disorder and Pd-Ag. SAD appears to be a more severe form of anxiety than Pd-Ag. There may be a need to refine items to include the reasons for avoiding leaving home, reluctance to sleep alone and to embark on trips, to ensure accurate discrimination between Pd-Ag and SAD in adulthood.

Patients with vestibular disease have been observed to have concomitant cognitive and psychiatric dysfunction. We evaluated the association between vestibular vertigo, cognitive impairment and psychiatric conditions in a nationally representative sample of US adults. We performed a cross-sectional analysis using the 2008 National Health Interview Survey (NHIS), which included a Balance and Dizziness Supplement, and questions about cognitive function and psychiatric comorbidity. We evaluated the association between vestibular vertigo, cognitive impairment (memory loss, difficulty concentrating, confusion) and psychiatric diagnoses (depression, anxiety and panic disorder). We observed an 8.4% 1-year prevalence of vestibular vertigo among US adults. In adjusted analyses, individuals with vestibular vertigo had an eightfold increased odds of 'serious difficulty concentrating or remembering' (OR 8.3, 95% CI 4.8 to 14.6) and a fourfold increased odds of activity limitation due to difficulty remembering or confusion (OR 3.9, 95% CI 3.1 to 5.0) relative to the rest of the US adults. Individuals with vestibular vertigo also had a threefold increased odds of depression (OR 3.4, 95% CI 2.9 to 3.9), anxiety (OR 3.2, 95% CI 2.8 to 3.6) and panic disorder (OR 3.4, 95% CI 2.9 to 4.0). Our findings indicate that vestibular impairment is associated with increased risk of cognitive and psychiatric comorbidity. The vestibular system is anatomically connected with widespread regions of the cerebral cortex, hippocampus and amygdala. Loss of vestibular inputs may lead to impairment of these cognitive and affective circuits. Further longitudinal research is required to determine if these associations are causal.

Our purpose was to determine if migraine, anxiety comorbidities, and chronic depression were independently related to health-related quality of life (HRQoL) in outpatients with major depressive disorder (MDD). Consecutive psychiatric outpatients with MDD in a medical center were enrolled. MDD, chronic depression, and seven anxiety disorders were diagnosed using the Structured Clinical Interview for DSM-IV-TR. Migraine was diagnosed based on the International Classification of Headache Disorders, 2nd edition. The acute version of the Short-Form 36 and the Hamilton Depression Rating Scale (HAMD) were used to evaluate the HRQoL and the severity of depression, respectively. Multiple linear regressions were used to determine the independent factors related to HRQoL. There were 135 participants (34 men, 101 women) with MDD. Subjects with migraine, anxiety comorbidities, or chronic depression had higher HAMD scores and poor HRQoL. Migraine, specific phobia, and panic disorder were important and independent comorbidities predicting HRQoL. The impact of migraine on HRQoL, especially on bodily pain, was not inferior to those of some anxiety comorbidities or chronic depression. Future studies related to HRQoL of MDD should consider migraine and anxiety comorbidities simultaneously.

The concept of obsessive-compulsive spectrum disorders (OCSDs) has become so influential that there are proposals to introduce it into new diagnostic classificatory systems. The aim of this paper was to assess whether rates of comorbidity and family history of OCSDs in patients with obsessive-compulsive disorder (OCD) supported this concept. Comorbidity and family history were assessed in a group of participants with a primary diagnosis of OCD, using structured clinical interviews. Rates of OCSDs and other anxiety disorders (OADs), excluding OCD, were compared. Of the 77 OCD participants assessed, the most prevalent comorbid conditions were OADs: generalized anxiety disorder (34.6%), specific phobia (26.9%), social phobia (21.8%) and panic disorder (19.2%). The proposed OCSDs were less frequently comorbid: tic disorder (12.8%), trichotillomania (5.1%), hypochondriasis (3.8%) and body dysmorphic disorder (BDD) (3.8%). Similar trends were observed for a family history of these disorders. No participant reported a family history of an OCSD without a family history of an OAD. Although the concept of OCSDs has invigorated thinking in this complex diagnostic field, these results support the current association of OCD with OADs rather than with OCSDs.

Conditioned Fear Acquisition and Generalization in Generalized Anxiety Disorder.

Abnormal fear conditioning processes (including fear acquisition and conditioned fear-generalization) have been implicated in the pathogenesis of anxiety disorders. Previous research has shown that individuals with panic disorder present enhanced conditioned fear-generalization in comparison to healthy controls. Enhanced conditioned fear-generalization could also characterize generalized anxiety disorder (GAD), but research so far is inconclusive. An important confounding factor in previous research is comorbidity. The present study examined conditioned fear-acquisition and fear-generalization in 28 patients with GAD and 30 healthy controls using a recently developed fear acquisition and generalization paradigm assessing fear-potentiated startle and online expectancies of the unconditioned stimulus. Analyses focused on GAD patients without comorbidity but included also patients with comorbid anxiety disorders. Patients and controls did not differ as regards fear acquisition. However, contrary to our hypothesis, both groups did not differ either in most indexes of conditioned fear-generalization. Moreover, dimensional measures of GAD symptoms were not correlated with conditioned fear-generalization indexes. Comorbidity did not have a significant impact on the results. Our data suggest that conditioned fear-generalization is not enhanced in GAD. Results are discussed with special attention to the possible effects of comorbidity on fear learning abnormalities.

'Judging a book by its cover': An experimental study of the negative impact of a diagnosis of borderline personality disorder on clinicians' judgements of uncomplicated panic disorder.

Diagnosis is ubiquitous in Psychiatry, and whilst it does bring benefits; adverse effects of 'labelling' may also be possible. This study aimed to evaluate experimentally whether clinicians' judgements about a patient with panic disorder were influenced by an inappropriately suggested diagnosis of comorbid borderline personality disorder (BPD). An experimental design was used to evaluate clinician's judgements when the nature of the information they were given was varied to imply BPD comorbidity. Two hundred and sixty-five clinicians watched a video-recorded assessment of a woman describing her experience of uncomplicated 'panic disorder' and then rated her present problems and likely prognosis. Prior to watching the video recording, participants were randomly allocated to one of three conditions with written information including the following: (1) her personal details and general background; (2) the addition of a behavioural description consistent with BPD; and (3) the further addition of a 'label' (past BPD diagnosis). The BPD label was associated with more negative ratings of the woman's problems and her prognosis than both information alone and a behavioural description of BPD 'symptoms'. Regardless of potential actuarial value of such diagnoses, it is concluded that clinicians can be overly influenced by past diagnostic labels in the context of an apparent current comorbid problem, although such biases appear to be less likely if a description of the relevant behaviours is used instead. Thus, the label, rather than the behaviour it denotes, may be stigmatizing in mental health professionals. Diagnostic labels can have an inappropriately negative effect on clinicians' judgements not only of treatment variables such as engagement and response but also risk issues and interpersonal effectiveness. Diagnostic labels can have a greater effect on clinicians' judgements than a behavioural description or clinical presentation. Clinicians should therefore be cautious both in the use of diagnostic labels to describe patients and ensure that these are still valid, and also be mindful of the influence that such labels can have on their own clinical judgements and constantly seek to challenge these. Behavioural descriptions of difficulties are less likely to result in such negative judgements and predictions. © 2015 The British Psychological Society.

Bioterrorism for the respiratory physician.

Waterer, Grant W; Robertson, Hannah

2009-01-01

Terrorist attacks by definition are designed to cause fear and panic. There is no question that a terrorist attack using biological agents would present a grave threat to stability of the society in which they were released. Early recognition of such a bioterrorist attack is crucial to containing the damage they could cause. As many of the most likely bioterrorism agents present with pulmonary disease, respiratory physicians may be crucial in the initial recognition and diagnosis phase, and certainly would be drawn into treatment of affected individuals. This review focuses on the biological agents thought most likely to be used by terrorists that have predominantly respiratory presentations. The primary focus of this review is on anthrax, plague, tularaemia, ricin, and Staphylococcal enterotoxin B. The pathogenesis, clinical manifestations and treatment of these agents will be discussed as well as historical examples of their use. Other potential bioterrorism agents with respiratory manifestations will also be discussed briefly.

Disorder-specific cognitive behavior therapy (DS-CBT) is effective at treating major depressive disorder (MDD) while transdiagnostic CBT (TD-CBT) addresses both principal and comorbid disorders by targeting underlying and common symptoms. The relative benefits of these two models of therapy have not been determined. Participants with MDD (n=290) were randomly allocated to receive an internet delivered TD-CBT or DS-CBT intervention delivered in either clinician-guided (CG-CBT) or self-guided (SG-CBT) formats. Large reductions in symptoms of MDD (Cohen's d≥1.44; avg. reduction≥45%) and moderate-to-large reductions in symptoms of comorbid generalised anxiety disorder (Cohen's d≥1.08; avg. reduction≥43%), social anxiety disorder (Cohen's d≥0.65; avg. reduction≥29%) and panic disorder (Cohen's d≥0.45; avg. reduction≥31%) were found. No marked or consistent differences were observed across the four conditions, highlighting the efficacy of different forms of CBT at treating MDD and comorbid disorders. Copyright © 2015 The Authors.

Validity of the adolescent version of the World Health Organization Composite International Diagnostic Interview (CIDI) Version 3.0, a fully-structured research diagnostic interview designed to be used by trained lay interviewers, is assessed in comparison to independent clinical diagnoses based on the Schedule for Affective Disorders and Schizophrenia for School-age Children (K-SADS). This assessment is carried out in the clinical reappraisal sub-sample (n = 347) of the US National Comorbidity Survey Adolescent (NCS-A) supplement, a large (n = 10,148) community epidemiological survey of the prevalence and correlates of adolescent mental disorders in the United States. The diagnoses considered are panic disorder and phobic disorders (social phobia, specific phobia, agoraphobia). CIDI diagnoses are found to have good concordance with K-SADS diagnoses [area under the receiver operating characteristic curve (AUC) = 0.81-0.94], although the CIDI diagnoses are consistency somewhat higher than the K-SADS diagnoses. Data are also presented on criterion-level concordance in an effort to pinpoint CIDI question series that might be improved in future modifications of the instrument. Finally, data are presented on the factor structure of the fears associated with social phobia, the only disorder in this series where substantial controversy exists about disorder subtypes.

Anxiety disorders may be encountered by the medical practitioner in the form of phobias, panic disorder or generalized anxiety disorder. A phobia is characterized by a strong, irrational fear of a given object or situation, often resulting in avoidance behavior. Phobic patients usually respond well to cognitive behavioral therapy. Panic disorder, which is distinguished by recurring, unexpected attacks of fear not bound to particular situations, may also be treated with cognitive behavioral therapy and/or with clomipramin, benzodiazepines or selective serotonin reuptake inhibitors. Patients with generalized anxiety disorder, the main symptom of which is a persistent, free-floating fear over a period of at least several months, may be helped through relaxation techniques, counseling and/or medication with low doses of sedating tricyclic compounds or short-term treatment with benzodiazepines. This article will describe anamnestic findings and the results of clinical examinations of patients with anxiety disorders. Factors to be considered in differential diagnosis will be discussed.

Very little epidemiological work has examined comorbidity between depression and anxiety disorders in community-dwelling older adults, despite the fact these disorders are known to co-occur in younger adults and that this co-occurrence is associated with greater clinical severity. In this study, the authors examine psychiatric comorbidity and associated impairment of four disorders (major depression, panic disorder, social phobia, and agoraphobia) in a community-based sample of adults aged 55 and older. Population-based sample of older adults (N=12,792) from the Canadian Community Health Survey-Mental Health and Well-Being (CCHS 1.2). The World Mental Health Composite International Diagnostic Interview was used to identify cases of 12-month disorder. Descriptive analysis and regression analysis is used to examine patterns of association between disorders and related impairment. Among adults aged 55 years and older, 4.4% met the criteria for at least one disorder and 0.8% had two or more. Social phobia was the most common comorbid disorder among respondents with depression, and depression was the most common comorbid disorder among respondents with any of the anxiety disorders. Respondents who report comorbid disorders reported significantly lower well-being and greater impairment. Although comorbidity between physical health conditions and depression, and between dementias and depression, are well documented among older adults, these results suggest that comorbid depression and anxiety are also prevalent in later life. The significant impact of comorbidity on function and well-being underlines the need to screen for comorbid disorders in this population.

To determine the effectiveness of manualized panic-focused psychodynamic psychotherapy (PFPP) in routine care in Germany. German psychoanalysts were trained according to the PFPP manual. Fifty-four consecutive outpatients with panic disorder (with or without agoraphobia) were randomly assigned in a 2:1 ratio to PFPP or cognitive-behavioural therapy (CBT) plus exposure therapy. Subjects (female 57.4%; mean age 36.2 years) had high rates of psychiatric (68.5%) and somatic (64.8%) comorbidity, and previous psychiatric treatments (57.4%). Assessments were performed pre- and posttreatment and at 6-month follow-up. The primary outcome measure was the Panic Disorder Severity Scale. Both treatments were highly effective. In patients randomized to PFPP, remission was achieved in 44.4% at termination and by 50% at follow-up (CBT 61.1% and 55.6%, respectively). No significant differences were found. Emotional awareness, a posited moderator of good outcome in psychotherapies, was significantly higher in the CBT group at baseline. It was found to be a strong moderator of treatment effectiveness in both treatments. After adjusting for initial Levels of Emotional Awareness Scale (LEAS) scores, effect sizes (ESs) for the primary outcome were Cohen d = 1.28, from pre- to posttreatment, and d = 1.03, from pretreatment to follow-up, for PFPP, and d = 1.81 and 1.28 for CBT, respectively. PFPP was implemented effectively into clinical practice by psychoanalysts in the community in a sample with severe mental illness with large ESs. Assessment of LEAS may facilitate the identification of patients suitable for short-term psychotherapy. ( German Clinical Trials Register, DRKS00000245; Universal Trial Number, U1111-1112-4245).

Gambling has become an increasingly common activity among women since the widespread growth of the gambling industry. Currently, our knowledge of the relationship between problem gambling among women and mental and physical correlates is limited. Therefore, important relationships between problem gambling and health and functioning, mental disorders, physical health conditions, and help-seeking behaviours among women were examined using a nationally representative Canadian sample. Data were from the nationally representative Canadian Community Health Survey Cycle 1.2 (CCHS 1.2; n = 10,056 women aged 15 years and older; data collected in 2002). The statistical analysis included binary logistic regression, multinomial logistic regression, and linear regression models. Past 12-month problem gambling was associated with a significantly higher probability of current lower general health, suicidal ideation and attempts, decreased psychological well-being, increased distress, depression, mania, panic attacks, social phobia, agoraphobia, alcohol dependence, any mental disorder, comorbidity of mental disorders, chronic bronchitis, fibromyalgia, migraine headaches, help-seeking from a professional, attending a self-help group, and calling a telephone help line (odds ratios ranged from 1.5 to 8.2). Problem gambling was associated with a broad range of negative health correlates among women. Problem gambling is an important public health concern. These findings can be used to inform healthy public policies on gambling.

Overview and clinical presentation of generalized anxiety disorder.

1. To distinguish GAD from panic disorder is not difficult if a patient has frequent, spontaneous panic attacks and agoraphobic symptoms, but many patients with GAD have occasional anxiety attacks or panic attacks. Such patients should be considered as having GAD. An even closer overlap probably exists between GAD and social phobia. Patients with clear-cut phobic avoidant behavior may be distinguished easily from patients with GAD, but patients with social anxiety without clear-cut phobic avoidant behavior may overlap with patients with GAD and possibly should be diagnosed as having GAD and not social phobia. The cardinal symptoms of GAD commonly overlap with those of social phobia, particularly if the social phobia is more general and not focused on a phobic situation. For example, free-floating anxiety may cause the hands to perspire and may cause a person to be shy in dealing with people in public, and thus many patients with subthreshold social phobic symptoms have, in the authors' opinion, GAD and not generalized social phobia. The distinction between GAD and obsessive-compulsive disorder, acute stress disorder, and posttraumatic stress disorder should not be difficult by definition. At times, however, it may be difficult to distinguish between adjustment disorder with anxious mood from GAD or anxiety not otherwise specified, particularly if the adjustment disorder occurs in a patient with a high level of neuroticism or trait anxiety or type C personality disorder. Table 2 presents features distinguishing GAD from other psychiatric disorders. 2. Lifetime comorbid diagnoses of other anxiety or depression disorders, not active for 1 year or more and not necessitating treatment during that time period, should not effect a diagnosis of current GAD. On the other hand, if concomitant depressive symptoms are present and if these are subthreshold, a diagnosis of GAD should be made, and if these are full threshold, a diagnosis of MDD should be made. 3. If GAD is primary and if no such current comorbid diagnosis, such as other anxiety disorders or MDD, is present, except for minor depression and dysthymia, or if only subthreshold symptoms of other anxiety disorders are present, GAD should be considered primary and treated as GAD; however, patients with concurrent threshold anxiety or mood disorders should be diagnosed according to the definitions of these disorders in the DSM-IV and ICD-10 and treated as such. 4. Somatization disorders are now classified separately from anxiety disorders. Some of these, particularly undifferentiated somatization disorder, may overlap with GAD and be diagnostically difficult to distinguish. The authors believe that, as long as psychic symptoms of anxiety are present and predominant, patients should be given a primary diagnosis of GAD. 5. Two major shifts in the DSM diagnostic criteria for GAD have markedly redefined the definition of this disorder. One shift involves the duration criterion from 1 to 6 months, and the other, the increased emphasis on worry and secondary psychic [table: see text] symptoms accompanied by the elimination of most somatic symptoms. This decision has had the consequence of orphaning a large population of patients suffering from GAD that is more transient and somatic in its focus and who typically present not to psychiatrists but to primary care physicians. Therefore, clinicians should consider using the ICD-10 qualification of illness duration of "several months" to replace the more rigid DSM-IV criterion of 6 months and to move away from the DSM-IV focus on excessive worry as the cardinal symptom of anxiety and demote it to only another important anxiety symptom, similar to free-floating anxiety. One also might consider supplementing this ICD-10 criterion with an increased symptom severity criterion as, for example, a Hamilton Anxiety Scale of 18. Finally, the adjective excessive, not used in the definition of other primary diagnostic criteria, such as depressed mood for MDD, should be omitted (Table 3). 6. One may want to consider the distinction of trait (chronic) from state (acute) anxiety, but whether the presence of some personality characteristics, particularly anxious personality or Cluster C personality and increased neuroticism, as an indicator of trait [table: see text] anxiety is a prerequisite for anxiety disorders; occurs independently of anxiety disorders; or is a vulnerability factor that, in some patients, leads to anxiety symptoms and, in others, does not, is unknown. 7. Symptoms that some clinicians consider cardinal for a diagnosis of GAD, such as extreme worry, obsessive rumination, and somatization, also are present in other disorders, such as MDD.

This article focuses on the possibility that autism spectrum disorder (ASD: Asperger syndrome, autism and atypical autism) in its milder forms may be clinically important among a substantial proportion of patients with obsessive-compulsive disorder (OCD), and discusses OCD subtypes based on this proposition. The hypothesis derives from extensive clinical experience of OCD and ASD, and literature searches on MEDLINE. Neuropsychological deficits are more common in OCD than in panic disorder and depression. Moreover, obsessive-compulsive and schizotypal personality disorders are over-represented in OCD. These may constitute mis-perceived clinical manifestations of ASD. Furthermore, repetitive behaviours and hoarding are common in Asperger syndrome. It is suggested that the comorbidity results in a more severe and treatment resistant form of OCD. OCD with comorbid ASD should be recognized as a valid OCD subtype, analogous to OCD with comorbid tics. An odd personality, with paranoid, schizotypal, avoidant or obsessive-compulsive traits, may indicate these autistic dimensions in OCD patients.

To compare prey and snake paradigms performed in complex environments to the elevated plus-maze (EPM) and T-maze (ETM) tests for the study of panic attack- and anticipatory anxiety-like behaviors in rodents. PubMed was reviewed in search of articles focusing on the plus maze test, EPM, and ETM, as well as on defensive behaviors displayed by threatened rodents. In addition, the authors' research with polygonal arenas and complex labyrinth (designed by the first author for confrontation between snakes and small rodents) was examined. The EPM and ETM tests evoke anxiety/fear-related defensive responses that are pharmacologically validated, whereas the confrontation between rodents and snakes in polygonal arenas with or without shelters or in the complex labyrinth offers ethological conditions for studying more complex defensive behaviors and the effects of anxiolytic and panicolytic drugs. Prey vs. predator paradigms also allow discrimination between non-oriented and oriented escape behavior. Both EPM and ETM simple labyrinths are excellent apparatuses for the study of anxiety- and instinctive fear-related responses, respectively. The confrontation between rodents and snakes in polygonal arenas, however, offers a more ethological environment for addressing both unconditioned and conditioned fear-induced behaviors and the effects of anxiolytic and panicolytic drugs.

This study examined the latent structure of psychiatric disorders in a sample with a high prevalence of PTSD. A series of confirmatory factor analyses tested competing models for the covariation between SCID diagnoses among 1,325 Vietnam veterans. The best fitting solution was a three-factor model that included two correlated internalizing factors: anxious-misery, defined by PTSD and major depression, and fear, defined by panic disorder/agoraphobia and obsessive-compulsive disorder. The third factor, externalizing, was defined by antisocial personality disorder, alcohol abuse/dependence, and drug abuse/dependence. Both substance-related disorders also showed significant, albeit smaller, cross-loadings on the anxious-misery factor. These findings shed new light on the structure of psychiatric comorbidity in a treatment-seeking sample characterized by high rates of PTSD. PMID:18302181

Comorbid mood and anxiety disorders are commonly seen in clinical practice. The goal of this article is to review the available literature on the epidemiologic, etiologic, clinical, and management aspects of this comorbidity and formulate a set of evidence- and consensus-based recommendations. This article is part of a set of Canadian Network for Mood and Anxiety Treatments (CANMAT) Comorbidity Task Force papers. We conducted a PubMed search of all English-language articles published between January 1966 and November 2010. The search terms were bipolar disorder and major depressive disorder, cross-referenced with anxiety disorders/symptoms, panic disorder, agoraphobia, generalized anxiety disorder, social phobia, obsessive-compulsive disorder, and posttraumatic stress disorder. Levels of evidence for specific interventions were assigned based on a priori determined criteria, and recommendations were developed by integrating the level of evidence and clinical opinion of the authors. Comorbid anxiety symptoms and disorders have a significant impact on the clinical presentation and treatment approach for patients with mood disorders. A set of recommendations are provided for the management of bipolar disorder (BD) with comorbid anxiety and major depressive disorder (MDD) with comorbid anxiety with a focus on comorbid posttraumatic stress disorder, use of cognitive-behavioral therapy across mood and anxiety disorders, and youth with mood and anxiety disorders. Careful attention should be given to correctly identifying anxiety comorbidities in patients with BD or MDD. Consideration of evidence- or consensus-based treatment recommendations for the management of both mood and anxiety symptoms is warranted.

Background More data is needed to guide next step interventions for panic disorder refractory to initial intervention. Method This 24-week randomized clinical trial (RCT) consisted of three phases. Phase 1 is a 6-week lead-in with open-label sertraline flexibly dosed to 100mg (or escitalopram equivalent) to prospectively define treatment refractoriness (lack of remission). Phase 2 is a six-week double blind RCT of (1) increased dose serotonin selective reuptake inhibitor (SSRI) versus (2) continued SSRI plus placebo. Phase 3 is a 12-week RCT of added cognitive-behavioral therapy (CBT) compared to “medication-optimization” (MO) with SSRI plus clonazepam. Primary endpoints were remission and change in Panic Disorder Severity Scale (PDSS) score in the intent to treat sample in each phase. Results In Phase 1, 20.5% (8/39) achieved remission, and only baseline severity predicted endpoint PDSS (β (SE)= 1.04(0.15), t=6.76, p<0.000). In Phase 2, increasing the SSRI dose did not result in greater improvement or remission rates (placebo 15% [n=2] vs. increased dose 9%[n=1]: FET p=n.s.). In Phase 3, remission was minimal (MO = 11%; CBT =10%), with a lack of group difference in PDSS reduction (t(df)=0.51(17), p>0.60) consistent with a small effect size (d=0.24). Conclusion Although power was limited and larger studies are needed, we failed to find evidence for greater benefit of increased SSRI dose versus continuation of current dose for panic disorder symptomatic after 6 weeks at moderate dose. Further, augmentation with CBT or medication optimization with clonazepam augmentation in non-remitted panic after 12 weeks of an SSRI did not differ, suggesting both are reasonable next-step options. However, low overall remission rates in this comorbid refractory population suggest better predictors of response to specific treatments over time and additional interventions are needed.

Intravenous injections of potassium cyanide (KCN) both elicit escape by its own and facilitate escape to electrical stimulation of the periaqueductal gray matter (PAG). Moreover, whereas the KCN-evoked escape is potentiated by CO 2 , it is suppressed by both lesions of PAG and clinically effective treatments with panicolytics. These and other data suggest that the PAG harbors a hypoxia-sensitive alarm system the activation of which could both precipitate panic and render the subject hypersensitive to CO 2 . Although prior c-Fos immunohistochemistry studies reported widespread activations of PAG following KCN injections, the employment of repeated injections of high doses of KCN (>60µg) in anesthetized rats compromised both the localization of KCN-responsive areas and their correlation with escape behavior. Accordingly, here we compared the brainstem activations of saline-injected controls (air/saline) with those produced by a single intravenous injection of 40-µg KCN (air/KCN), a 2-min exposure to 13% CO 2 (CO 2 /saline), or a combined stimulus (CO 2 /KCN). Behavioral effects of KCN microinjections into the PAG were assessed as well. Data showed that whereas the KCN microinjections were ineffective, KCN intravenous injections elicited escape in all tested rats. Moreover, whereas the CO 2 alone was ineffective, it potentiated the KCN-evoked escape. Compared to controls, the nucleus tractus solitarius was significantly activated in both CO 2 /saline and CO 2 /KCN groups. Additionally, whereas the laterodorsal tegmental nucleus was activated by all treatments, the rostrolateral and caudoventrolateral PAG were activated by air/KCN only. Data suggest that the latter structures are key components of a hypoxia-sensitive suffocation alarm which activation may trigger a panic attack. Copyright © 2017 IBRO. Published by Elsevier Ltd.

It has been suggested that antidepressant benefits are smaller for mild than severe depression. Because antidepressants are also used for anxiety disorders, obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD), we examined the influence of severity for these disorders. We used individual patient data of eight trials (3,430 participants) for generalized anxiety disorder (GAD); four trials (1,195 participants) for social anxiety disorder (SAD); four trials (1,132 participants) for OCD; three trials (1,071 participants) for PTSD; and 10 trials (2,151 participants) for panic disorder (PD). Mixed-effects models were used to investigate an interaction between severity and treatment group. For GAD and PD, severity moderated antidepressant efficacy. The antidepressant-placebo difference was 1.4 (95% CI: 0.4-2.5; SMD: 0.21) Hamilton Anxiety Rating Scale (HAM-A) points for participants with mild GAD (baseline HAM-A = 10), increasing to 4.0 (3.4-4.6; SMD: 0.45) or greater for severely ill participants (HAM-A ≥ 30). For PD, the difference was 0.4 (0.3-0.6) panic attacks/2 weeks for participants with 10 panic attacks/2 weeks at baseline, increasing to 4.7 (3.0-6.4) for participants with 40. For SAD, OCD, and PTSD, no interaction was found. Across severity levels, the differences were 16.1 (12.9-19.3; SMD: 0.59) Liebowitz Social Anxiety Scale points, 3.4 (2.5-4.4, SMD: 0.39) Yale-Brown Obsessive-Compulsive Scale points, and 10.3 (6.9-13.6; SMD: 0.41) Clinician-Administered PTSD Scale points. Antidepressants are equally effective across severity levels for SAD, OCD, and PTSD. For GAD and PD, however, benefits are small at low severity, and the benefit-risk ratio may be unfavorable for these patients. © 2018 Wiley Periodicals, Inc.

The Khmer ‘Weak Heart’ Syndrome: Fear of Death from Palpitations

PubMed Central

Hinton, Devon; Hinton, Susan; Um, Khin; Chea, Audria; Sak, Sophia

2009-01-01

According to the Khmer conception, a person suffering ‘weak heart’ (khsaoy beh daung) has episodes of palpitations on slight provocation (e.g. triggered by orthostasis, anger, a noise, worry, an odor or exercise) and runs the risk of dying of heart arrest during these periods of palpitations; too, the sufferer typically has other symptoms attributed to the purported cardiac dysfunction: fatigue, shortness of breath, and orthostatic dizziness. Many Khmer refugees suffer this cultural syndrome, an anxious–dysphoria ontology, most probably of French colonial provenance. The syndrome demonstrates considerable overlap with those Western illness categories that feature panic attacks, in particular post-traumatic stress disorder (PTSD) and panic disorder. In a psychiatric clinic survey, 60 percent (60/100) of those assessed believed themselves to currently suffer ‘weak heart’; 90 percent (54/60) of those considering themselves to suffer from ‘weak heart’ thought that palpitations (e.g., those resulting from a loud noise or orthostasis) might result in death. The article illustrates the profoundly culturally constructed nature of ‘cardiac sensations,’ located in a specific historical trajectory and episteme; too, the article suggests that trauma may result more in panic disorder than ‘PTSD’ when autonomic arousal symptoms (in the present case, palpitations) are considered potentially life-threatening.

The purpose of this study was to determine the nature and extent of comorbidity among patients with DSM-III-R hypochondriasis and to examine the relationships between this disorder and coexisting psychiatric illness. For this purpose, patients seen in a general medicine clinic were screened using measures of hypochondriacal attitudes and somatic symptoms. Those scoring above an established cutoff were given a structured diagnostic interview. In this manner, 50 patients who met DSM-III-R criteria for hypochondriasis and 50 age- and sex-matched controls were identified. The presence of other psychiatric disorders (current and past) was determined by means of the same diagnostic interview. More hypochondriacal subjects (62.0%) had lifetime comorbidity than did controls (30.0%). Major depression, the most frequent comorbid disturbance, was usually current and most often had an onset after that of hypochondriasis. Panic disorder with agoraphobia, the most frequent anxiety disorder, was also current but often began before or at the same time as hypochondriasis. Few subjects met criteria for somatization disorder but a third qualified for a subsyndromal form of this disorder. The data show that, in medical outpatients with hypochondriasis, mood and anxiety disorders frequently coexist. This comorbidity is subject to varying interpretations including overlap of symptom criteria, treatment-seeking bias, and the possibility that hypochondriasis predisposes to or causes the comorbid disorder, as seems likely in the case of depression. In some instances hypochondriasis may be an associated feature of another illness.

Cognitive Behavioral Therapy vs. Eye Movement Desensitization and Reprocessing for Treating Panic Disorder: A Randomized Controlled Trial

Objective: Cognitive Behavioral Therapy (CBT) is an effective intervention for patients with panic disorder (PD). From a theoretical perspective, Eye Movement Desensitization and Reprocessing (EMDR) therapy could also be useful in the treatment of PD because: (1) panic attacks can be experienced as life threatening; (2) panic memories specific to PD resemble traumatic memories as seen in posttraumatic stress disorder (PTSD); and (3) PD often develops following a distressing life event. The primary objective of this Randomized Controlled Trial (RCT), was to compare EMDR therapy with CBT for PD and determine whether EMDR is not worse than CBT in reducing panic symptoms and improving Quality Of Life (QOL). Methods: Two-arm (CBT and EMDR) parallel RCT in patients with PD (N = 84). Patients were measured at baseline (T1), directly after the last therapy session (T2), and 3 months after ending therapy (T3). Non-inferiority testing (linear mixed model with intention-to-treat analysis) was applied. Patients were randomly assigned to 13 weekly 60-min sessions of CBT (N = 42) or EMDR therapy (N = 42). Standard protocols were used. The primary outcome measure was severity of PD at T3, as measured with the Agoraphobic Cognitions Questionnaire (ACQ), the Body Sensations Questionnaire (BSQ), and the Mobility Inventory (MI). The secondary outcome measure was QOL, as measured with the World Health Organization Quality of Life short version (WHOQOL-Bref), at T3. Results: The severity of PD variables ACQ and BSQ showed non-inferiority of EMDR to CBT, while MI was inconclusive (adjusted analyses). Overall QOL and general health, Psychological health, Social relationships, and Environment showed non-inferiority of EMDR to CBT, while Physical health was inconclusive. Conclusion: EMDR therapy proved to be as effective as CBT for treating PD patients.

This is a complex case of post-traumatic stress disorder (PTSD) with comorbid panic disorder occurring in a woman in her mid-60s, with a family history of neurotic illness. PTSD arose in the context of treatment for terminal lung cancer. This patient who had been close to her father watched him die of cancer, when he was about her age. Her diagnosis and treatment prompted traumatic recollections of her father's illness and death that resulted in her voluntary withdrawal from cancer treatment. The goals of treatment were to promptly reduce anxiety, minimise use of sedating pharmacotherapy, promote lucidity and prolong anxiety-free state thereby allowing time for important family interactions. Prompt, sustained relief of severe anxiety was necessary to achieve comfort at the end of life. Skilled additions of psychological therapies (eye movement desensitisation reprocessing, clinical hypnosis and breathing exercises) with combined pharmacotherapy (mirtazepine and quetiapine) led to control of anxiety and reduction of post-traumatic stress.

We describe the rationale, method, and intake demographic and clinical findings of the Harvard/Brown Anxiety Research Project-Phase II (HARP-II). HARP-II is the first prospective, observational, longitudinal study to describe the characteristics and course of anxiety in African American, Latino, and Non-Latino White individuals. Participants met criteria for at least one of the following disorders: Generalized Anxiety Disorder, Social Phobia, Panic Disorder with or without Agoraphobia, Agoraphobia without history of Panic Disorder, Posttraumatic Stress Disorder. Initial intake data, collected between 2004 and 2011, are presented for 165 African American, 150 Latino, and 172 Non-Latino White participants. Participants evidenced substantial psychiatric comorbidity (mean number of Axis I disorders = 3.4), and moderate to severe symptoms and functional impairment. HARP-II will examine clinical course, in the context of potential socio-cultural and individual moderators (e.g., discrimination, acculturation, negative affect). Results should lead to improved understanding, prognostics, and treatment of anxiety in diverse populations. PMID:22410095

Background Previous work has suggested significant associations between various psychological symptoms (e.g. depression, anxiety, anger, alcohol abuse) and hypertension. However, the presence and extent of associations between common mental disorders and subsequent adult onset of hypertension remains unclear. Further, there is little data available on how such associations vary by gender or over life course. Methods Data from the World Mental Health Surveys (comprising 19 countries, and 52,095 adults) were used. Survival analyses estimated associations between first onset of common mental disorders and subsequent onset of hypertension, with and without psychiatric comorbidity adjustment. Variations in the strength of associations by gender and by life course stage of onset of both the mental disorder and hypertension were investigated. Results After psychiatric comorbidity adjustment, depression, panic disorder, social phobia, specific phobia, binge eating disorder, bulimia nervosa, alcohol abuse, and drug abuse were significantly associated with subsequent diagnosis of hypertension (with ORs ranging from 1.1 to 1.6). Number of lifetime mental disorders was associated with subsequent hypertension in a dose-response fashion. For social phobia and alcohol abuse, associations with hypertension were stronger for males than females. For panic disorder, the association with hypertension was particularly apparent in earlier onset hypertension. Conclusions Depression, anxiety, impulsive eating disorders, and substance use disorders disorders were significantly associated with the subsequent diagnosis of hypertension. These data underscore the importance of early detection of mental disorders, and of physical health monitoring in people with these conditions.. PMID:24342112

Recent reports indicate that bipolar disorder is frequently underdiagnosed in the clinical population, leading to overuse of antidepressants and underuse of mood stabilizers. This study assessed rates of diagnosis of bipolar disorder in a substance abuse population. The study involved a retrospective chart review of data from 295 patients admitted to an inpatient substance abuse program for men. Data were then analyzed from the 85 patients in the sample who were diagnosed as meeting DSM-IV criteria for bipolar disorder on intake into the program. Charts were reviewed for relevant clinical and demographic data. The primary outcome measure was the rate of previous misdiagnosis. Of the 85 patients diagnosed with bipolar disorder upon intake, 42 (49%) had not been previously diagnosed with bipolar disorder; of these 42, 6 (14%) patients had not been assessed previously, while 36 (86%) had been assessed previously and had received many other psychiatric diagnoses, including major depression (77%), attention-deficit/hyperactivity disorder (20%), and panic disorder (3%). Among the comorbid substance use disorders in these patients, alcohol dependence was the most common (62%), followed by cocaine (38%), opioid (26%), polysubstance (12%), and sedative-hypnotic (2%) dependence. Other comorbid Axis I disorders included posttraumatic stress disorder (14%), attention-deficit/hyperactivity disorder (10%), panic disorder (2%), and generalized anxiety disorder (2%). This study found that bipolar disorder had not been previously diagnosed in approximately 50% of a sample of Caucasian males in a substance abuse population who were diagnosed with bipolar disorder upon admission to an inpatient substance abuse program.

Anxiety sensitivity as a predictor of broad dimensions of psychopathology after cognitive behavioral therapy for panic disorder.

Panic disorder (PD) is a common disease and presents with broad dimensions of psychopathology. Cognitive behavioral therapy (CBT) is known to improve these broad dimensions of psychopathology in addition to PD symptoms. However, little is known about the predictors of treatment response in comorbid psychiatric symptoms after CBT for PD. Recent studies suggest that anxiety sensitivity (AS) may be a key vulnerability for PD. This study aimed to examine AS as a predictor of broad dimensions of psychopathology after CBT for PD. In total, 118 patients with PD were treated with manualized group CBT. We used multiple regression analysis to examine the associations between 3 Anxiety Sensitivity Index (ASI) factors (physical concerns, mental incapacitation concerns, and social concerns) at baseline and the subscales of the Symptom Checklist-90 Revised (SCL-90-R) at endpoint. Low levels of social concerns at baseline predicted low levels on 5 SCL-90-R subscales after CBT: interpersonal sensitivity, depression, hostility, paranoid ideation, and psychosis. High levels of mental incapacitation concerns significantly predicted low levels on 3 SCL-90-R subscales after treatment: interpersonal sensitivity, hostility, and paranoid ideation. Physical concerns at baseline did not predict broad dimensions of psychopathology. This study suggested that the social concerns and mental incapacitation concerns subscales of the ASI at baseline predicted several dimensions of psychopathology after CBT for PD. To improve comorbid psychopathology, it may be useful to direct more attention to these ASI subscales.

The phenomenology of dissociative disorders may be complex and sometimes confusing. We describe here two cases who were initially misdiagnosed. The first case concerned a 61 year-old woman, who was initially diagnosed as an isolated dissociative fugue and was actually suffering from severe major depressive episode. The second case concerned a 55 year-old man, who was suffering from type I bipolar disorder and polyvascular disease, and was initially diagnosed as dissociative fugue in a mooddestabilization context, while it was finally a stroke. Yet dissociative disorders as affective disorder comorbidity are relatively unknown. We made a review on this topic. Dissociative disorders are often studied through psycho-trauma issues. Litterature is rare on affective illness comorbid with dissociative disorders, but highlight the link between bipolar and dissociative disorders. The later comorbidity often refers to an early onset subtype with also comorbid panic and depersonalization-derealization disorder. Besides, unipolar patients suffering from dissociative symptoms have more often cyclothymic affective temperament. Despite the limits of such studies dissociative symptoms-BD association seems to correspond to a clinical reality and further works on this topic may be warranted. Copyright © 2014 L’Encéphale.

This study evaluated the clinical and sociodemographic features associated with various degrees of concurrent comorbidity in adult outpatients with nonpsychotic major depressive disorder (MDD). Outpatients enrolled in the STAR*D trial completed the Psychiatric Diagnostic Screening Questionnaire (PDSQ). An a priori 90% specificity threshold was set for PDSQ responses to ascertain the presence of 11 different concurrent DSM-IV Axis I disorders. Of 1376 outpatients, 38.2% had no concurrent comorbidities, while 25.6% suffered one, 16.1% suffered two, and 20.2% suffered three or more comorbid conditions. Altogether, 29.3% met threshold for social anxiety disorder, 20.8% for generalized anxiety disorder, 18.8% for posttraumatic stress disorder, 12.4% for bulimia, 11.9% for alcohol abuse/dependence, 13.4% for obsessive-compulsive disorder, 11.1% for panic disorder, 9.4% for agoraphobia, 7.3% for drug abuse/dependence, 3.7% for hypochondriasis, and 2.2% for somatoform disorder. Those with more concurrent Axis I conditions had earlier ages at first onset of MDD, longer histories of MDD, greater depressive symptom severity, more general medical comorbidity (even though they were younger than those with fewer comorbid conditions), poorer physical and mental function, health perceptions, and life satisfaction; and were more likely to be seen in primary care settings. Participants had to meet entry criteria for STAR*D. Ascertainment of comorbid conditions was not based on a structured interview. Concurrent Axis I conditions (most often anxiety disorders) are very common with MDD. Greater numbers of concurrent comorbid conditions were associated with increased severity, morbidity, and chronicity of their MDD.

Panic disorder is characterised by repeated, unexpected panic attacks, which represent a discrete period of fear or anxiety that has a rapid onset, reaches a peak within 10 minutes, and in which at least four of 13 characteristic symptoms are experienced, including racing heart, chest pain, sweating, shaking, dizziness, flushing, stomach churning, faintness and breathlessness. It is common in the general population with a lifetime prevalence of 1% to 4%. The treatment of panic disorder includes psychological and pharmacological interventions. Amongst pharmacological agents, the National Institute for Health and Care Excellence (NICE) and the British Association for Psychopharmacology consider antidepressants, mainly selective serotonin reuptake inhibitors (SSRIs), as the first-line treatment for panic disorder, due to their more favourable adverse effect profile over monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). Several classes of antidepressants have been studied and compared, but it is still unclear which antidepressants have a more or less favourable profile in terms of effectiveness and acceptability in the treatment of this condition. To assess the effects of antidepressants for panic disorder in adults, specifically:1. to determine the efficacy of antidepressants in alleviating symptoms of panic disorder, with or without agoraphobia, in comparison to placebo;2. to review the acceptability of antidepressants in panic disorder, with or without agoraphobia, in comparison with placebo; and3. to investigate the adverse effects of antidepressants in panic disorder, with or without agoraphobia, including the general prevalence of adverse effects, compared to placebo. We searched the Cochrane Common Mental Disorders' (CCMD) Specialised Register, and CENTRAL, MEDLINE, EMBASE and PsycINFO up to May 2017. We handsearched reference lists of relevant papers and previous systematic reviews. All double-blind, randomised, controlled trials (RCTs) allocating adults with panic disorder to antidepressants or placebo. Two review authors independently checked eligibility and extracted data using a standard form. We entered data into Review Manager 5 using a double-check procedure. Information extracted included study characteristics, participant characteristics, intervention details and settings. Primary outcomes included failure to respond, measured by a range of response scales, and treatment acceptability, measured by total number of dropouts for any reason. Secondary outcomes included failure to remit, panic symptom scales, frequency of panic attacks, agoraphobia, general anxiety, depression, social functioning, quality of life and patient satisfaction, measured by various scales as defined in individual studies. We used GRADE to assess the quality of the evidence for each outcome MAIN RESULTS: Forty-one unique RCTs including 9377 participants overall, of whom we included 8252 in the 49 placebo-controlled arms of interest (antidepressant as monotherapy and placebo alone) in this review. The majority of studies were of moderate to low quality due to inconsistency, imprecision and unclear risk of selection and performance bias.We found low-quality evidence that revealed a benefit for antidepressants as a group in comparison with placebo in terms of efficacy measured as failure to respond (risk ratio (RR) 0.72, 95% confidence interval (CI) 0.66 to 0.79; participants = 6500; studies = 30). The magnitude of effect corresponds to a number needed to treat for an additional beneficial outcome (NNTB) of 7 (95% CI 6 to 9): that means seven people would need to be treated with antidepressants in order for one to benefit. We observed the same finding when classes of antidepressants were compared with placebo.Moderate-quality evidence suggested a benefit for antidepressants compared to placebo when looking at number of dropouts due to any cause (RR 0.88, 95% CI 0.81 to 0.97; participants = 7850; studies = 30). The magnitude of effect corresponds to a NNTB of 27 (95% CI 17 to 105); treating 27 people will result in one person fewer dropping out. Considering antidepressant classes, TCAs showed a benefit over placebo, while for SSRIs and serotonin-norepinephrine reuptake inhibitor (SNRIs) we observed no difference.When looking at dropouts due to adverse effects, which can be considered as a measure of tolerability, we found moderate-quality evidence showing that antidepressants as a whole are less well tolerated than placebo. In particular, TCAs and SSRIs produced more dropouts due to adverse effects in comparison with placebo, while the confidence interval for SNRI, noradrenergic reuptake inhibitors (NRI) and other antidepressants were wide and included the possibility of no difference. The identified studies comprehensively address the objectives of the present review.Based on these results, antidepressants may be more effective than placebo in treating panic disorder. Efficacy can be quantified as a NNTB of 7, implying that seven people need to be treated with antidepressants in order for one to benefit. Antidepressants may also have benefit in comparison with placebo in terms of number of dropouts, but a less favourable profile in terms of dropout due to adverse effects. However, the tolerability profile varied between different classes of antidepressants.The choice of whether antidepressants should be prescribed in clinical practice cannot be made on the basis of this review.Limitations in results include funding of some studies by pharmaceutical companies, and only assessing short-term outcomes.Data from the present review will be included in a network meta-analysis of psychopharmacological treatment in panic disorder, which will hopefully provide further useful information on this issue.

Previous research has focussed extensively on the distinction of HPA-axis functioning between patient groups and healthy volunteers, with relatively little emphasis on a direct comparison of patient groups. The current study's aim was to analyse differences in the cortisol stress response as a function of primary diagnosis of panic disorder (PD), post-traumatic stress disorder (PTSD), and major depressive disorder (MDD). A total of n=30 PD (mean age±SD: 36.07±12.56), n=23 PTSD (41.22±10.17), n=18 MDD patients (39.00±14.93) and n=47 healthy control (HC) individuals (35.51±13.15) participated in this study. All the study participants were female. The Trier Social Stress Test (TSST) was used for reliable laboratory stress induction. Blood sampling accompanied the TSST for cortisol and ACTH assessment. Panic-related, PTSD-specific questionnaires and the Beck Depression Inventory II were handed out for the characterisation of the study groups. Repeated measure ANCOVAs were conducted to test for main effects of time or group and for interaction effects. Regression analyses were conducted to take comorbid depression into account. 26.7% of the PD patients, 43.5% of the PTSD patients, 72.2% of the MDD patients and 80.6% of the HC participants showed a cortisol stress response upon the TSST. ANCOVA revealed a cortisol hypo-responsiveness both in PD and PTSD patients, while no significant group differences were seen in the ACTH concentrations. Additional analyses showed no impact of comorbid depressiveness on the cortisol stress response. MDD patients did not differ in the hormonal stress response neither compared to the HC participants nor to the PD and PTSD patients. Our main findings provide evidence of a dissociation between the cortisol and ACTH concentrations in response to the TSST in PTSD and in PD patients, independent of comorbid depression. Our results further support overall research findings of a cortisol hypo-responsiveness in PD patients. A hypo-response pattern was also seen in the PTSD patients agreeing with previous finding on the cortisol stress reactivity following TSST stress induction in these patients. Patients with a primary MDD diagnosis showed descriptively higher cortisol concentrations compared to the anxiety patients, and lower cortisol concentrations as the healthy individuals. The limitations of the study and implications for future studies will be discussed. Copyright © 2017. Published by Elsevier Ltd.

Background Obsessive–compulsive disorder (OCD) is probably an etiologically heterogeneous condition. Many patients manifest other psychiatric syndromes. This study investigated the relationship between OCD and co-morbid conditions to identify subtypes. Method Seven hundred and six individuals with OCD were assessed in the OCD Collaborative Genetics Study (OCGS). Multi-level latent class analysis was conducted based on the presence of eight co-morbid psychiatric conditions [generalized anxiety disorder (GAD), major depression, panic disorder (PD), separation anxiety disorder (SAD), tics, mania, somatization disorders (Som) and grooming disorders (GrD)]. The relationship of the derived classes to specific clinical characteristics was investigated. Results Two and three classes of OCD syndromes emerge from the analyses. The two-class solution describes lesser and greater co-morbidity classes and the more descriptive three-class solution is characterized by: (1) an OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder; (2) an OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and (3) an OCD co-morbid affective-related class in which PD and affective syndromes are highly represented. The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive–compulsive personality disorder (OCPD) features, high scores on the ‘taboo’ factor of OCD symptoms, and low conscientiousness. Conclusions OCD can be classified into three classes based on co-morbidity. Membership within a class is differentially associated with other clinical characteristics. These classes, if replicated, should have important implications for research and clinical endeavors. PMID:19046474

Diagnosis and management of generalized anxiety disorder and panic disorder in adults.

Generalized anxiety disorder (GAD) and panic disorder (PD) are among the most common mental disorders in the United States, and they can negatively impact a patient's quality of life and disrupt important activities of daily living. Evidence suggests that the rates of missed diagnoses and misdiagnosis of GAD and PD are high, with symptoms often ascribed to physical causes. Diagnosing GAD and PD requires a broad differential and caution to identify confounding variables and comorbid conditions. Screening and monitoring tools can be used to help make the diagnosis and monitor response to therapy. The GAD-7 and the Severity Measure for Panic Disorder are free diagnostic tools. Successful outcomes may require a combination of treatment modalities tailored to the individual patient. Treatment often includes medications such as selective serotonin reuptake inhibitors and/or psychotherapy, both of which are highly effective. Among psychotherapeutic treatments, cognitive behavior therapy has been studied widely and has an extensive evidence base. Benzodiazepines are effective in reducing anxiety symptoms, but their use is limited by risk of abuse and adverse effect profiles. Physical activity can reduce symptoms of GAD and PD. A number of complementary and alternative treatments are often used; however, evidence is limited for most. Several common botanicals and supplements can potentiate serotonin syndrome when used in combination with antidepressants. Medication should be continued for 12 months before tapering to prevent relapse.

Despite well-established links between poverty and poor mental illness outcome as well as recent reports exploring racial and ethnic health disparities, little is known about the outcomes of evidence-based psychiatric treatment for poor individuals. Primary care patients with panic disorder (N=232) who were participating in a randomized controlled trial comparing a cognitive behavior therapy (CBT) and pharmacotherapy intervention to usual care were divided into those patients above (N=152) and below (N=80) the poverty line. Telephone assessments at 3, 6, 9, and 12 months were used to compare the amount of evidence-based care received as well as clinical and functional outcomes. Poor subjects were more severely ill at baseline, with more medical and psychiatric comorbidity. The increases in the amount of evidence-based care and reductions in clinical symptoms and disability were comparable in the two groups such that poorer individuals, although responding equivalently, continued to be more ill and disabled at 12 months. The comparable response of poor individuals in this study suggests that standard CBT and pharmacotherapy treatments for panic disorder do not need to be "tailored" to be effective in poor populations. However, the more severe illness both at baseline and follow-up in these poor individuals suggests that treatment programs may need to be extended in order to treat residual symptoms and disability in these patients so that they might achieve comparable levels of remission.

Efficacy of self-help internet-based cognitive behavior therapy (ICBT) for anxiety disorders has been confirmed in several randomized controlled trials. However, the amount and type of therapist guidance needed in ICBT are still under debate. Previous studies have shown divergent results regarding the role of therapist guidance and its impact on treatment outcome. This issue is central to the development of ICBT programs and needs to be addressed directly. The present study aims to compare the benefits of regular therapist guidance via online real-time audio-video communication (i.e. Skype) to no therapist guidance during a 12-week Romanian self-help ICBT program for Panic Disorder. Both treatments are compared to a waiting-list control group. A parallel group randomized controlled trial is proposed. The participants, 192 Romanian adults fulfilling diagnostic criteria for panic disorder according to a diagnostic interview, conducted via secured Skype or telephone, are randomly assigned to one of the three conditions: independent use of the internet-based self-help program PAXonline, the same self-help treatment with regular therapist support via secured Skype, and waiting-list control group. The primary outcomes are severity of self-report panic symptoms (PDSS-SR) and diagnostic status (assessors are blind to group assignment), at the end of the intervention (12 weeks) and at follow-up (months 3 and 6). The secondary measures address symptoms of comorbid anxiety disorders, depression, quality of life, adherence and satisfaction with ICBT. Additional measures of socio-demographic characteristics, personality traits, treatment expectancies, catastrophic cognitions, body vigilance and working alliance are considered as potential moderators and/ or mediators of treatment outcome. To the best of our knowledge, the present study is the first effort to investigate the efficacy of a self-help internet-based intervention with therapist guidance via real-time video communication. A direct comparison between therapist guided versus unguided self-directed intervention for panic disorder will also be addressed for the first time. Findings from this study will inform researchers and practitioners about the added value of online video-therapy guidance sessions and the type of patients who may benefit the most from guided and unguided ICBT for Panic disorder.

[Depression and anxiety--a study for validating subtypes of depression].

Psychopathological analysis of the patterns of symptoms in 176 depressive in-patients disclosed in 73.3% of all patients the presence of anxiety symptoms: of these, 38.6% merely had diffuse anxiety, whereas 34.7% showed either additionally or alone specific anxiety symptoms such as phobias and panic attacks. Similar to the results obtained by dividing the patients into an "endogenous" and "neurotic" group, namely, that there was no difference between the subtypes in respect of triggering the depressive episodes by life events, or in respect of the suicide rate 30 months after discharge and in respect of a chronic course developing during the 2 years following the discharge, there was likewise no difference with regard to these criteria if the patients were subdivided into depressive patients without anxiety and those with anxiety symptoms. However, a subdivision of the depressive patients with anxiety symptoms into a group having only free-floating anxiety and a group with specific anxiety symptoms, resulted in a clear association with these criteria: If a phobia or panic attacks were present, triggering by life events was far more frequent than if there was only free-floating was more often chronic in the first group, but there was no difference in suicidality. The results indicate that it will be necessary to provide for a more differentiated classification of anxiety symptoms before deciding in clinical routine what steps to take wherever depression and anxiety symptoms are present side by side. The same applies to treatment studies.

Illness Attitudes Scale dimensions and their associations with anxiety-related constructs in a nonclinical sample.

The Illness Attitudes Scale (IAS) is a self-rated measure that consists of nine subscales designed to assess fears, attitudes and beliefs associated with hypochondriacal concerns and abnormal illness behavior [Kellner, R. (1986). Somatization and hypochondriasis. New York: Praeger; Kellner, R. (1987). Abridged manual of the Illness Attitudes Scale. Department of Psychiatry, School of Medicine, University of New Mexico]. The purposes of the present study were to explore the hierarchical factor structure of the IAS in a nonclinical sample of young adult volunteers and to examine the relations of each illness attitudes dimension to a set of anxiety-related measures. One-hundred and ninety-seven undergraduate university students (156 F, 41 M; mean age = 21.9 years) completed the IAS as well as measures of anxiety sensitivity, trait anxiety and panic attack history. The results of principal components analyses with oblique (Oblimin) rotation suggested that the IAS is best conceptualized as a four-factor measure at the lower order level (with lower-order dimensions tapping illness-related Fears, Behavior, Beliefs and Effects, respectively), and a unifactorial measure at the higher-order level (i.e. higher-order dimension tapping General Hypochondriacal Concerns). The factor structure overlapped to some degree with the scoring of the IAS proposed by Kellner (1986, 1987), as well as with the factor structures identified in previously-tested clinical and nonclinical samples [Ferguson, E. & Daniel, E. (1995). The Illness Attitudes Scale (IAS): a psychometric evaluation on a nonclinical population. Personality and Individual Differences, 18, 463-469; Hadjistavropoulos, H. D. & Asmundson, G. J. G. (1998). Factor analytic investigation of the Illness Attitudes Scale in a chronic pain sample. Behaviour Research and Therapy, 36, 1185-1195; Hadjistavropoulos, H. D., Frombach, I. & Asmundson, G. J. G. (in press). Exploratory and confirmatory factor analytic investigations of the Illness Attitudes Scale in a nonclinical sample. Behaviour Research and Therapy; Speckens, A. E., Spinhoven, P., Sloekers, P. P. A., Bolk, J. H. & van Hemert, A. M. (1996). A validation study of the Whitley Index, the Illness Attitude Scales and the Somatosensory Amplification Scale in general medical and general practice patients. Journal of Psychosomatic Research, 40, 95-104]. The Fears, Beliefs and Effects lower-order factors and the General Hypochondriacal Concerns higher-order factor, were shown to be strongly associated with anxiety sensitivity, even after accounting for trait anxiety and panic history. Implications for understanding the high degree of comorbidity between the diagnoses of panic disorder and hypochondriasis, as well as future research directions for exploring the utility of various IAS dimensions in predicting responses to lab-based bodily symptom-induction procedures, are discussed.

Bipolar II and unipolar comorbidity in 153 outpatients with social phobia.

Previous studies on social phobia (SP) have focused largely on comorbidity between SP and major depression. Less attention has been devoted to the comorbidity between SP and bipolar disorder. In this retrospective study, we investigated family history, lifetime comorbidity, and demographic and clinical characteristics among 153 outpatients who met DSM-III-R diagnostic criteria for SP. Information regarding axis I diagnoses was obtained using the Structured Clinical Interview for DSM III-R (SCID-UP-R). Social phobic symptoms and the severity of the illness were assessed by the Liebowitz Social Anxiety Scale (LSAS) and the Liebowitz Social Phobic Disorders Rating Scale, Severity (LSPDRS). Patients completed the Hopkins Symptom Checklist (HSCL 90). Fourteen patients (9.1%) satisfied DSM-III-R criteria for lifetime bipolar disorder not otherwise specified (NOS) (bipolar II), while 71 (46.4%) had unipolar major depression and 68 (44.4%) had no lifetime history of major mood disorders. Comorbid panic disorder/agoraphobia (PDA), obsessive-compulsive disorder (OCD), and alcohol abuse were reported more frequently in the bipolar group than in the other two subgroups. Unipolar patients showed higher rates of comordid PDA and OCD compared with SP patients without mood disorders. Severity and generalization of the SP symptoms, prevalent interactional anxiety, multiple comorbidity, and alcohol abuse appeared to be the most relevant consequences of SP-bipolar coexistence. In a significant minority of cases, protracted social anxiety may hypothetically have represented, along with inhibited depression, the dimensional opposite of gregarious hypomania.

Panic attacks are thought to be a result from a dysfunctional coordination of cortical and brainstem sensory information leading to heightened amygdala activity with subsequent neuroendocrine, autonomic and behavioral activation. Prefrontal areas may be responsible for inhibitory top-down control processes and alpha synchronization seems to reflect this modulation. The objective of this study was to measure frontal absolute alpha-power with qEEG in 24 subjects with panic disorder and agoraphobia (PDA) compared to 21 healthy controls. qEEG data were acquired while participants watched a computer simulation, consisting of moments classified as "high anxiety"(HAM) and "low anxiety" (LAM). qEEG data were also acquired during two rest conditions, before and after the computer simulation display. We observed a higher absolute alpha-power in controls when compared to the PDA patients while watching the computer simulation. The main finding was an interaction between the moment and group factors on frontal cortex. Our findings suggest that the decreased alpha-power in the frontal cortex for the PDA group may reflect a state of high excitability. Our results suggest a possible deficiency in top-down control processes of anxiety reflected by a low absolute alpha-power in the PDA group while watching the computer simulation and they highlight that prefrontal regions and frontal region nearby the temporal area are recruited during the exposure to anxiogenic stimuli. © 2013 Elsevier B.V.

The goals of this study were to estimate the prevalence of the DSM-5 anxious distress specifier (AD) among depressed outpatients, to examine associations of AD with comorbid diagnoses, and to test the incremental validity of AD over comorbidity in predicting functional impairment and severity of anxiety and depression symptoms. The sample was 237 outpatients diagnosed with major depressive disorder (MDD) or persistent depressive disorder (PDD), with and without AD, using the Anxiety and Related Disorders Interview Schedule for DSM-5. Outpatients also completed self-report questionnaires assessing functional impairment and anxiety, stress, and depression symptom severity. Two-by-two contingency tables were used to examine the associations of AD with comorbidity. Two-thirds (66.2%) of outpatients were assigned AD, with similar rates among those with MDD and PDD. Outpatients with AD were significantly more likely than those without AD to have a comorbid GAD diagnosis (OR = 2.47). Hierarchical multiple regressions were used to test the incremental validity of AD in predicting functional impairment and symptom outcomes beyond comorbid disorders. Controlling for comorbid disorders, AD was significantly associated with more severe functional impairment, autonomic arousal, stress, panic, generalized anxiety, and depression. The strongest incremental association were observed between AD and autonomic arousal (f 2  = 0.12-0.18) and generalized anxiety (f 2  = 0.17). These findings add to a growing literature that AD is common among outpatients and associated with important clinical outcomes, suggesting that AD should be routinely assessed in patients with mood disorders.

Social anxiety disorder and social fears in the Canadian military: prevalence, comorbidity, impairment, and treatment-seeking.

Mather, Amber A; Stein, Murray B; Sareen, Jitender

Military mental health research has rarely investigated social anxiety disorder, despite its known serious consequences in the general population, and what work has been conducted has used specialized samples (e.g., veterans) not representative of all military personnel. Data were from the 2002 Canadian Community Health Survey-Canadian Forces Supplement, a representative survey of 8441 active regular and reserve military personnel. Social anxiety disorder has a high lifetime (8.2%) and past-year (3.2%) prevalence in the military. It is associated with increased odds of depression, panic attacks/disorder, generalized anxiety disorder, and post-traumatic stress disorder (AOR range 4.16-16.29). Being female, ages 35-44, or separated/divorced/widowed increases the odds of having social anxiety disorder, while being an officer or a reservist decreases the odds. Treatment-seeking, as in the general population, is relatively rare. Overall, military personnel with social anxiety disorder experience significant rates of role impairment in all domains (53.1-88.3% report some impairment), with the rate of role impairment increasing with the number of social fears. Notably, many (70.6%) report at least some impairment at work (i.e., in their job with the military). Social anxiety disorder is an important disorder to take into account when considering military mental health. Observing low rates of treatment-seeking for social anxiety disorder among military personnel highlights the importance of initiatives to allow its identification and treatment.

To determine whether the presence of anxiety disorders is related to depressive comorbidity in subjects with eating disorders (ED), while taking into account certain variables that may be related to depression (subjects' age, ED duration, prior incidents of anorexia nervosa in bulimic subjects, inpatient or outpatient status, nutritional state [as measured by body mass index]). We evaluated the frequency of depressive disorders in 271 subjects presenting with a diagnosis of either anorexia nervosa or bulimia, using the Mini International Neuropsychiatric Interview, DSM-IV version. A multivariate analysis reveals that anxiety disorders do not all have the same influence in terms of risk of onset of major depressive episode in anorexics and bulimics when adjusted on variables related to depression. Depression in subjects with ED can be explained in part by comorbidity with obsessive-compulsive disorder, generalized anxiety, social phobia, and panic disorder.
