    Bipolar disorder is a chronic mental health disorder that is frequently encountered in primary care. Many patients with depression may actually have bipolar disorder. The management of bipolar disorder requires proper diagnosis and awareness or referral for appropriate pharmacologic therapy. Patients with bipolar disorder require primary care management for comorbidities such as cardiovascular and metabolic disorders. PMID:27262007

    Background Bipolar disorder (BD) is a serious mental illness with adverse impact on the lives of the patients and their caregivers. BD is associated with many limitations in personal and interpersonal functioning and restricts the patients’ ability to use their potential capabilities fully. Bipolar patients long to live meaningful lives, but this goal is hard to achieve for those with poor insight. With progress and humanization of society, the issue of patients’ needs became an important topic. The objective of the paper is to provide the up-to-date data on the unmet needs of BD patients and their caregivers. Methods A systematic computerized examination of MEDLINE publications from 1970 to 2015, via the keywords “bipolar disorder”, “mania”, “bipolar depression”, and “unmet needs”, was performed. Results Patients’ needs may differ in various stages of the disorder and may have different origin and goals. Thus, we divided them into five groups relating to their nature: those connected with symptoms, treatment, quality of life, family, and pharmacotherapy. We suggested several implications of these needs for pharmacotherapy and psychotherapy. Conclusion Trying to follow patients’ needs may be a crucial point in the treatment of BD patients. However, many needs remain unmet due to both medical and social factors. PMID:27445475

    2015-12-01

    Perugi and colleagues (2013) recently reported that some features of borderline personality disorder (BPD) significantly predicted a diagnosis of bipolar disorder among depressed patients. They interpreted these findings as indicating that some BPD criteria are nonspecific and are indicators of bipolar disorder rather than BPD, whereas other criteria are more specific to BPD. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, the authors tested the hypothesis that BPD presents itself differently in psychiatric outpatients diagnosed with bipolar disorder or major depressive disorder. The authors found that the patients with bipolar disorder were significantly more likely to report impulsive behavior and transient dissociation. No criterion was significantly more common in the BPD patients with MDD. The authors therefore do not consider the BPD criteria to be nonspecific with regard to the distinction between BPD and bipolar disorder.

    Background Testosterone influences well-being, mood and cognition and may play a role in the pathophysiology of bipolar disorder. Aim To examine testosterone levels in patients with bipolar disorder compared with healthy controls. Method We examined baseline total testosterone levels and current depression scores in male and female patients with bipolar disorder and mild to moderate depression and healthy controls. Results A significant interaction between diagnosis and gender was observed (F(2,97)=9.791, P=0.002). Testosterone levels were significantly lower for male patients with bipolar disorder compared with male controls (P=0.001). Women with bipolar disorder had significantly higher testosterone levels than female controls (P=0.03). Conclusions Disturbances in testosterone levels may represent an important neurobiological abnormality in bipolar disorder and may differ by gender. If these findings are confirmed, the use of gender appropriate treatment strategies for the normalisation of testosterone levels in bipolar disorder depression should be further explored.

  9. ESPECTRA: Searching the Bipolar Spectrum in Eating Disorder patients

    PubMed Central

    2011-01-01

    Background Bipolar Disorder (BD) is a chronic, recurrent and highly prevalent illness. Despite the need for correct diagnosis to allow proper treatment, studies have shown that reaching a diagnosis can take up to ten years due to the lack of recognition of the broader presentations of BD. Frequent comorbidities with other psychiatric disorders are a major cause of misdiagnosis and warrant thorough evaluation. Methods/Design ESPECTRA (Occurrence of Bipolar Spectrum Disorders in Eating Disorder Patients) is a single-site cross-sectional study involving a comparison group, designed to evaluate the prevalence of bipolar spectrum in an eating disorder sample. Women aged 18-45 years will be evaluated using the SCID-P and Zurich criteria for diagnosis and the HAM-D, YOUNG, SCI-MOODS, HCL-32, BIS-11, BSQ, WHOQoL and EAS instruments for rating symptoms and measuring clinical correlates. Discussion The classificatory systems in psychiatry are based on categorical models that have been criticized for simplifying the diagnosis and leading to an increase in comorbidities. Some dimensional approaches have been proposed aimed at improving the validity and reliability of psychiatric disorder assessments, especially in conditions with high rates of comorbidity such as BD and Eating Disorder (ED). The Bipolar Spectrum (BS) remains under-recognized in clinical practice and its definition is not well established in current diagnostic guidelines. Broader evaluation of psychiatric disorders combining categorical and dimensional views could contribute to a more realistic understanding of comorbidities and help toward establishing a prognosis.

    Bipolar disorder's unique combination of three characteristics - clear genetic diathesis, distinctive clinical features, early availability of an effective treatment (lithium) - explains its special place in the history of psychiatry and its contribution to the current explosive growth of neuroscience. This article looks at the state of the art in bipolar disorder from the vantage point of: (i) genetics (possible linkages on chromosomes 18 and 21q, polygenic hypothesis, research into genetic markers); (ii) diagnosis (new focus on the subjective aspects of bipolar disorder to offset the current trend of underdiagnosis due to overreliance on standardized interviews and rating scales); (iii) outcome (increase in treatment-resistant forms signaling a change in the natural history of bipolar disorder); (iv) pathophysiology (research into circadian biological rhythms and the kindling hypothesis to explain recurrence); (v) treatment (emergence of the anticonvulsants, suggested role of chronic antidepressant treatment in the development of treatment resistance); (vi) neurobiology (evaluation of regulatory function in relation to affective disturbances, role of postsynaptic second-messenger mechanisms, advances in functional neuroimaging); and (vii) psychosocial research (shedding overly dualistic theories of the past to understand the mind and brain as an entity, thus emphasizing the importance of balancing the psychopharmacological and psychotherapeutic approaches). Future progress in the understanding and treatment of bipolar disorder will rely on successful integration of the biological and psychosocial lines of investigation. PMID:22033232

    Bipolar disorder (BD) is characterized by an alternated occurrence between acute mania episodes and depression or remission moments. The objective of this study is to analyze the information processing changes in BP (Bipolar Patients) (euthymia, depression and mania) during the oddball paradigm, focusing on the P300 component, an electric potential of the cerebral cortex generated in response to external sensorial stimuli, which involves more complex neurophysiological processes related to stimulus interpretation. Twenty-eight bipolar disorder patients (BP) (17 women and 11 men with average age of 32.5, SD: 9.5) and eleven healthy controls (HC) (7 women and 4 men with average age of 29.78, SD: 6.89) were enrolled in this study. The bipolar patients were divided into 3 major groups (i.e., euthymic, depressive and maniac) according to the score on the Clinical Global Impression--Bipolar Version (CGI-BP). The subjects performed the oddball paradigm simultaneously to the EEG record. EEG data were also recorded before and after the execution of the task. A one-way ANOVA was applied to compare the P300 component among the groups. After observing P300 and the subcomponents P3a and P3b, a similarity of amplitude and latency between euthymic and depressive patients was observed, as well as small amplitude in the pre-frontal cortex and reduced P3a response. This can be evidence of impaired information processing, cognitive flexibility, working memory, executive functions and ability to shift the attention and processing to the target and away from distracting stimuli in BD. Such neuropsychological impairments are related to different BD symptoms, which should be known and considered, in order to develop effective clinical treatment strategies. PMID:26551764

    In paper we apply the method based on the Flicker-Noise Spectroscopy (FNS) to determine the differences in frequency-phase synchronization of the cortical electroencephalographic (EEG) activities in patients with bipolar disorder (BD). We found that for healthy subjects the frequency-phase synchronization of EEGs from long-range electrodes was significantly better for BD patients. In BD patients a high synchronization of EEGs was observed only for short-range electrodes. Thus, the FNS is a simple graphical method for qualitative analysis can be applied to identify the synchronization effects in EEG activity and, probably, may be used for the diagnosis of this syndrome.

    The aim of this study was to compare differences in traumatic experiences between patients with bipolar I disorder, patients with major depressive disorder (MDD), and controls. The traumatic experiences (as measured by the Trauma Experience Questionnaire) of 40 participants with bipolar I disorder were compared with those of 38 participants with MDD and 92 controls. Participants with bipolar I disorder exhibited a significantly higher frequency of traumatic experiences and higher impact ratings when traumas did occur than did patients with MDD and controls. In addition, the present impact of past trauma for patients in the bipolar I disorder and MDD groups was significantly higher than for controls. The bipolar I disorder group reported more severe traumatic experiences than did both the MDD and control groups, and the MDD group in turn reported more severe traumatic experiences than did the control group.

    The onset of bipolar disorder (BD) secondary to a stroke event is a rare clinical entity. Although it may be related to specific regions of the brain, several other factors have been linked to its expression such as subcortical atrophy or chronic vascular burden. While precise locations and cerebral circuits involved in the bipolarity expression after stroke still need to be determined, their investigation represents an opportunity to study brain function and BD etiopathogenesis. We present a BD secondary to multiple subcortical biparietal lacunar infarctions, a lacunar infarction in left putamen and an ischemic lesion at the cerebral trunk evolving the right median portion, in a 65-year-old male patient who experienced manic, hypomanic, and depressive episodes, after 6, 10, and 16 months, respectively, of the cerebrovascular events.

    Objectives: To assess the impact of social anxiety disorder (SAD) comorbidity on the clinical features, illness severity, and response to mood stabilizers in bipolar disorder (BD) patients. Methods: This retrospective study included bipolar patients that were treated at the Department of Psychiatry, Haseki Training and Research Hospital, Istanbul, Turkey in 2015, and who provided their informed consents for participation in this study. The study was conducted by assessing patient files retrospectively. Two hundred bipolar patients were assessed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition axis-I (SCID-I) in order to detect all possible comorbid psychiatric diagnoses. The sample was split according to the presence of SAD comorbidity and the groups were compared. Results: The SAD comorbidity was detected in 17.5% (35/200) of the BD patients. The SAD comorbid bipolar patients were more educated, had earlier onset of BD, lower number of manic episodes, and more severe episodes. There was no difference between groups in terms of total number of episodes, hospitalization, suicidality, being psychotic, treatment response to lithium and anticonvulsants. Conclusion: Social anxiety disorder comorbidity may be associated with more severe episodes and early onset of BD. However, SAD comorbidity may not be related to treatment response in bipolar patients. PMID:26905355

    Abstract Antipsychotics are the drugs prescribed to treat psychotic disorders; however, patients often fail to adhere to their treatment, and this has a severe negative effect on prognosis in these kinds of illnesses. Among the wide range of risk factors for treatment nonadherence, this systematic review covers those that are most important from the point of view of clinicians and patients and proposes guidelines for addressing them. Analyzing 38 studies conducted in a total of 51,796 patients, including patients with schizophrenia spectrum disorders and bipolar disorder, we found that younger age, substance abuse, poor insight, cognitive impairments, low level of education, minority ethnicity, poor therapeutic alliance, experience of barriers to care, high intensity of delusional symptoms and suspiciousness, and low socioeconomic status are the main risk factors for medication nonadherence in both types of disorder. In the future, prospective studies should be conducted on the use of personalized patient-tailored treatments, taking into account risk factors that may affect each individual, to assess the ability of such approaches to improve adherence and hence prognosis in these patients.

    This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet. PMID:22649454

    In this article the contribution of neuropsychological research for a better understanding of the psychopathology of mood disorders is reviewed. First, the broad spectrum of bipolar disorders is described. Second, a selective review of important results of neuropsychological studies with patients with mood disorders is presented. Although several methodological problems limit the interpretation of the findings, there is evidence that patients with a bipolar disorder show a consistent impairment in attention, memory/learning and executive functions. The cognitive deficits are still visible during clinical recovery (euthymia) and closely associated with psychosocial limitation in daily life. Finally, the impact of neuropsychological findings is considered in relation to assessment, treatment and prognosis.

    Many long-term follow-up studies suggest that bipolar disorder (BD) is highly recurrent and that depressive episodes are commoner than hypomania/manic episodes. However, some studies from tropical countries including India suggest that the patients experience a greater proportion of manic episodes than depressive episodes. The aim of the present study was to examine the course of BD type 1 (BD I) in a sample of hospitalized Indian subjects. We examined the clinical course of 285 BD I subjects with at least 5 years of illness using standard life charting method. These subjects were hospitalized between October 2010 and October 2012. The predominant polarity (having at least two-thirds of their lifetime episodes at one polarity) was mania (79%). Unipolar mania (≥ 3 mania episodes and no episodes of depression) was observed in 48% of the subjects. The frequency of rapid cycling course was noted in 2.5% of the subjects. Predominant manic polarity group had the illness onset mostly with a manic episode (88.9%) and the predominant depressive polarity group with a depressive episode (73.8%). Mania was the predominant polarity with a high rate of unipolar mania and a majority of the subjects had greater number of manic episodes than depressive/mixed episodes. The onset polarity determined the predominant polarity during the course of illness. Predominantly, mania course could have significant implications in the treatment of bipolar disorder.

    We compared executive dysfunction with the Wisconsin Card Sorting Test (WCST) among distinct national and ethnic patients with bipolar disorder in euthymia. Bipolar patients, aged 16-45years, from the United States (n=25) and Taiwan (n=30) did not differ significantly on any measure. The WCST score for number Failure to Maintain Set was significantly positively correlated with residual affective symptoms in Taiwanese and US patients. Selective executive dysfunction in euthymia is inherent to bipolar disorder. Euthymic bipolar patients of various ethnic groups may exhibit similar executive dysfunction.

    Patients with bipolar disorder (BD) are more frequently affected by metabolic syndrome (MetS) than the general population, but the neurobiological correlates underlying such association are still not clarified and few studies in BD have evaluated the role of regulators of lipid and glucose metabolism. The present study was aimed to investigate putative alterations in markers linked to metabolic dysfunctions as C-peptide, Ghrelin, GIP, GLP-1, Glucagon, Insulin, Leptin, PAI-1 (total), Resistin and Visfatin in a sample of BD patients compared to controls. Furthermore, associations between changes of metabolic markers and relevant clinical features, such as severity of symptomatology, number and type of past mood episodes, drug treatments and presence/absence of metabolic alterations (MetS, diabetes and cardiovascular disease) were analyzed. A total of 57 patients with BD and 49 healthy controls were recruited. The main results showed lower serum levels of Glucagon, GLP-1, Ghrelin, and higher levels of GIP in BD patients as compared to controls (p = 0.018 for Ghrelin; p < 0.0001 for Glucagon; p < 0.0001 for GLP-1; p < 0.0001 for GIP). Further, Glucagon and GLP-1 levels were significantly associated with the number of past mood episodes. These findings support the hypothesis that alterations in Glucagon, GLP-1, GIP and Ghrelin might be involved in BD pathogenesis and might represent useful biomarkers for the development of preventive and personalized therapies in this disorder.

    There are no studies comparing platelet parameters platelet parameters (platelet count (PLT), mean platelet volume (MPV) and platelet large cell ratio (P-LCR)) between patients with schizophrenia, bipolar disorder and unipolar depression. Therefore, the aim of this study was to determine and compare differences in PLT, MPV and P-LCR in patients with schizophrenia, unipolar depression and bipolar disorder. This was a retrospective, cross-sectional, naturalistic study of 2377 patients (schizophrenia n=1243; unipolar depression n=791; bipolar disorder n=343, including bipolar depression n=259 and mania n=84). There were significant differences for PLT, MPV and P-LCR values between study groups. A significant percentage of patients with bipolar disorder had abnormal (too low or too high) number of platelets. Negative correlation between PLT and age was found in all study groups and positive correlation between age and MPV and P-LCR was found in patients with schizophrenia.

    Objective Little information is available on the need for dosage changes for lamotrigine in pregnant women with bipolar disorder. The authors present new data on serial serum levels of lamotrigine in pregnant patients on lamotrigine monotherapy. They also review the epilepsy literature on use of lamotrigine during pregnancy. Method Lamotrigine serum samples were obtained from eight mother-infant pairs at different time points during pregnancy and the postpartum period. Results All of the women were taking lamotrigine throughout pregnancy. Serum-level-to-dose ratios were lower during pregnancy than the postpartum period. Lamotrigine was taken once daily in doses ranging from 100 mg to 300 mg. Three patients had an increase of 50 mg to their daily dose across pregnancy. The change in serum lamotrigine levels in the postpartum period ranged from a 30% decrease to a 640% increase compared with the first level obtained during pregnancy. Level-to-dose ratios obtained within 4 weeks after delivery reflected a mean level 402% greater than the baseline level during gestation. Compared with the third trimester, lamotrigine serum concentration increased an average of 154% within 5 weeks after delivery. The most dramatic increase in lamotrigine serum level early after delivery occurred at 1.5 weeks. The mean infant cord level was 66% of the maternal serum level at delivery. The mean breast-fed infant serum level was 32.5% of the maternal serum levels. Conclusions The pattern of lamotrigine changes during pregnancy in these women with bipolar disorder was consistent with that described in the epilepsy literature. PMID:24185239

    Cardiovascular risk factors, such as abdominal obesity and obesity in general, are very prevalent among patients with bipolar disorder (BD). Although long-term use of psychotropic medications is an important determinant of these risk factors, other evidence suggests that early development may interact with the mood disorder diathesis to exponentially increase the risk of obesity. The goal of our study was to test whether season of birth is associated with adult body mass index (BMI) and abdominal obesity in individuals with bipolar disorder. We compared season of birth effects on BMI in 375 adult patients with bipolar disorder and 196 adult patients with unipolar major depression. We found a significant season of birth effect on BMI in patients with bipolar disorder, but not unipolar. In patients with bipolar disorder, season of birth was also associated with waist circumference, with a stronger effect in males. Season of birth affects adult BMI and waist circumference in patients with bipolar disorder, but not in patients with unipolar depression. Our results suggest that early environmental factors, yet to be identified, interact with specific neurobiological features of bipolar disorder to determine stable traits and disease risk factors in adult life.

    Diagnostic confusion sometimes exists between bipolar disorder and borderline personality disorder (BPD). To improve the recognition of bipolar disorder researchers have identified nondiagnostic factors that point toward bipolar disorder. One such factor is the presence of a family history of bipolar disorder. In the current report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we compared the demographic, clinical, and psychosocial characteristics of patients with BPD who did and did not have a family history of bipolar disorder. A large sample of psychiatric outpatients were interviewed with semi-structured interviews. Three hundred seventeen patients without bipolar disorder were diagnosed with DSM-IV borderline personality disorder. Slightly less than 10% of the 317 patients with BPD (9.5%, n=30) reported a family history of bipolar disorder in their first-degree relatives. There were no differences between groups in any specific Axis I or Axis II disorder. The patients with a positive family history were significantly less likely to report excessive or inappropriate anger, but there was no difference in the frequency of other criteria for BPD such as affective instability, impulsivity, or suicidal behavior. The patients with a positive family history reported a significantly higher rate of increased appetite and fatigue. There was no difference in overall severity of depression, scores on the Global Assessment of Functioning, history of psychiatric hospitalizations, suicide attempts, time unemployed due to psychiatric reasons during the 5 years before the evaluation, and ratings of current and adolescent social functioning. There was no difference on any of the 5 subscales of the childhood trauma questionnaire. Overall, we found few differences between BPD patients with and without a family history of bipolar disorder thereby suggesting that a positive family history of bipolar disorder was not a useful marker for

    Bipolar disorder is a complex neuropsychiatric disorder that is characterized by intermittent episodes of mania and depression; without treatment, 15% of patients commit suicide. Hence, it has been ranked by the World Health Organization as a top disorder of morbidity and lost productivity. Previous neuropathological studies have revealed a series of alterations in the brains of patients with bipolar disorder or animal models, such as reduced glial cell number in the prefrontal cortex of patients, upregulated activities of the protein kinase A and C pathways and changes in neurotransmission. However, the roles and causation of these changes in bipolar disorder have been too complex to exactly determine the pathology of the disease. Furthermore, although some patients show remarkable improvement with lithium treatment for yet unknown reasons, others are refractory to lithium treatment. Therefore, developing an accurate and powerful biological model for bipolar disorder has been a challenge. The introduction of induced pluripotent stem-cell (iPSC) technology has provided a new approach. Here we have developed an iPSC model for human bipolar disorder and investigated the cellular phenotypes of hippocampal dentate gyrus-like neurons derived from iPSCs of patients with bipolar disorder. Guided by RNA sequencing expression profiling, we have detected mitochondrial abnormalities in young neurons from patients with bipolar disorder by using mitochondrial assays; in addition, using both patch-clamp recording and somatic Ca(2+) imaging, we have observed hyperactive action-potential firing. This hyperexcitability phenotype of young neurons in bipolar disorder was selectively reversed by lithium treatment only in neurons derived from patients who also responded to lithium treatment. Therefore, hyperexcitability is one early endophenotype of bipolar disorder, and our model of iPSCs in this disease might be useful in developing new therapies and drugs aimed at its clinical

    There is considerable international interest in online education of patients with bipolar disorder, yet little understanding of how patients use the Internet and other sources to seek information. 1171 patients with a diagnosis of bipolar disorder in 17 countries completed a paper-based, anonymous survey. 81% of the patients used the Internet, a percentage similar to the general public. Older age, less education, and challenges in country telecommunications infrastructure and demographics decreased the odds of using the Internet. About 78% of the Internet users looked online for information on bipolar disorder or 63% of the total sample. More years of education in relation to the country mean, and feeling very confident about managing life decreased the odds of seeking information on bipolar disorder online, while having attended support groups increased the odds. Patients who looked online for information on bipolar disorder consulted medical professionals plus a mean of 2.3 other information sources such as books, physician handouts, and others with bipolar disorder. Patients not using the Internet consulted medical professionals plus a mean of 1.6 other information sources. The percentage of patients with bipolar disorder who use the Internet is about the same as the general public. Other information sources remain important.

    Impaired neuroplasticity may be implicated in the pathophysiology of bipolar disorder, involving peripheral alterations of the neurotrophins brain derived neurotrophic factor (BDNF) and neurotrophin 3 (NT-3). Evidence is limited by methodological issues and is based primarily on case-control designs. The aim of this study was to investigate whether BDNF and NT-3 levels differ between patients with rapid cycling bipolar disorder and healthy control subjects and whether BDNF and NT-3 levels alter with affective states in rapid cycling bipolar disorder patients. Plasma levels of BDNF and NT-3 were measured in 37 rapid cycling bipolar disorder patients and in 40 age- and gender matched healthy control subjects using enzyme-linked immunosorbent assay (ELISA). In a longitudinal design, repeated measurements of BDNF and NT-3 were evaluated in various affective states in bipolar disorder patients during a 6-12 months period and compared with repeated measurements in healthy control subjects. Careful attention was given to standardization of all procedures and adjustment for potential confounders of BDNF and NT-3. In linear mixed models, adjusting for demographical and lifestyle factors, levels of BDNF were significantly elevated in bipolar disorder patients in euthymic- (p<0.05), depressed- (p<0.005) and manic/hypomanic (p<0.005) states compared with healthy control subjects. Within bipolar disorder patients, adjusting for medication, there was no significant difference in BDNF levels between affective states, with equally elevated levels present in euthymic-, depressive- and manic/hypomanic patients. Levels of BDNF were higher in patients with longer duration of illness compared with patients with shorter duration of illness. We found no difference in NT-3 levels between bipolar disorder patients in any affective state compared with healthy control subjects and no difference in NT-3 levels between affective states in bipolar disorder patients. The results suggest that

    Techniques of behavioral family management (BFM), which have been found to be highly effective in delaying relapse for schizophrenic patients when used as adjuncts to medication maintenance, are also applicable in the outpatient treatment of recently hospitalized bipolar, manic patients. The authors describe their adaptation of the educational, communication skills training, and problem-solving skills training modules of BFM to families containing a bipolar member. The observations that families of bipolar patients are often high functioning, and that these families seem to enjoy interchanges that are highly affective and spontaneous, led to certain modifications in the original BFM approach. The authors found it necessary to be (a) more flexible and less didactic, (b) more oriented toward dealing with affect and resistance to change, and (c) more focused on the patient's and family members' feelings about labeling, stigmatization, and medication usage. Research issues relevant to testing the efficacy of this approach are also discussed. PMID:2252468

    Poor medication adherence is a pervasive problem that causes disability and suffering as well as extensive financial costs among individuals with bipolar disorder (BD). Barriers to adherence are numerous and cross multiple levels, including factors related to bipolar pathology and those unique to an individual's circumstances. External factors, including treatment setting, healthcare system, and broader health policies, can also affect medication adherence in people with BD. Fortunately, advances in research have suggested avenues for improving adherence. A comprehensive review of adherence-enhancement interventions for the years 2005-2015 is included. Specific bipolar adherence-enhancement approaches that target knowledge gaps, cognitive patterns, specific barriers, and motivation may be helpful, as may approaches that capitalize on technology or novel drug-delivery systems. However, much work remains to optimally facilitate long-term medication adherence in people with BD. For adherence-enhancement approaches to be widely adapted, they need to be easily accessible, affordable, and practical. PMID:27435356

We updated our recent systematic review searching the electronic databases MEDLINE, Embase, and PsycINFO to investigate course of illness in BD-OCD patients. We identified a total of 13 relevant papers which found that the majority of comorbid OCD cases appeared to be related to mood episodes. OC symptoms in comorbid patients appeared more often during depressive episodes, and comorbid BD and OCD cycled together, with OC symptoms often remitting during manic/hypomanic episodes.

    Bipolar disorder (also known as manic depressive illness) is a complex genetic disorder in which the core feature is pathological disturbance in mood (affect) ranging from extreme elation, or mania, to severe depression usually accompanied by disturbances in thinking and behaviour. The lifetime prevalence of 1% is similar in males and females and family, twin, and adoption studies provide robust evidence for a major genetic contribution to risk. There are methodological impediments to precise quantification, but the approximate lifetime risk of bipolar disorder in relatives of a bipolar proband are: monozygotic co-twin 40-70%; first degree relative 5-10%; unrelated person 0.5-1.5%. Occasional families may exist in which a single gene plays the major role in determining susceptibility, but the majority of bipolar disorder involves the interaction of multiple genes (epistasis) or more complex genetic mechanisms (such as dynamic mutation or imprinting). Molecular genetic positional and candidate gene approaches are being used for the genetic dissection of bipolar disorder. No gene has yet been identified but promising findings are emerging. Regions of interest identified in linkage studies include 4p16, 12q23-q24, 16p13, 21q22, and Xq24-q26. Chromosome 18 is also of interest but the findings are confusing with up to three possible regions implicated. To date most candidate gene studies have focused on neurotransmitter systems influenced by medication used in clinical management of the disorder but no robust positive findings have yet emerged. It is, however, almost certain that over the next few years bipolar susceptibility genes will be identified. This will have a major impact on our understanding of disease pathophysiology and will provide important opportunities to investigate the interaction between genetic and environmental factors involved in pathogenesis. This is likely to lead to major improvements in treatment and patient care but will also raise important

    Objective Patients with Bipolar disorder smoke more than the general population. Smoking negatively impacts mortality and clinical course in Bipolar disorder patients. Prior studies have shown contradictory results regarding the impact of psychosis on smoking behavior in Bipolar disorder. We analyzed a large sample of Bipolar disorder and Schizoaffective disorder, Bipolar Type patients and predicted those with a history of psychosis would be more likely to be nicotine dependent. Methods Data from subjects and controls were collected from the Genomic Psychiatry Cohort (GPC). Subjects were diagnosed with Bipolar disorder without psychosis (N=610), Bipolar disorder with psychosis (N=1591), and Schizoaffective Disorder, Bipolar Type (N=1544). Participants were classified with or without nicotine dependence. Diagnostic groups were compared to controls (N=10065) using logistic regression. Results Among smokers (N=6157), those with Bipolar disorder had an increased risk of nicotine dependence (OR=2.5; p<0.0001). Patients with Bipolar disorder with psychosis were more likely to be dependent than Bipolar disorder patients without psychosis (OR=1.3; p=0.03). Schizoaffective disorder, Bipolar Type patients had more risk of nicotine dependence when compared to Bipolar disorder patients with or without psychosis (OR=1.2; p=0.02). Conclusions Bipolar disorder patients experiencing more severity of psychosis have more risk of nicotine dependence. PMID:26467098

    Bipolar disorder is one of the most common, severe and persistent mental disorders. The evaluation of all data and variables related to bipolar disorder is a difficult task, because there is no clear agreement on what should be included in this category. One of the traditional treatments for this disease is the lithium metal that is administered in the form of lithium salt. Lithium has a narrow therapeutic window and there is a significant risk of complications arising from its use, mainly neurological and renal. In the case presented, the preparation of a care plan is described for a patient diagnosed with bipolar disorder who suffered a complication with lithium treatment. To do this, it was decided to use a standardized care plan and later completed it with diagnostic, objectives and interventions to the specific needs of the patient, aimed at achieving optimal levels of independence.

    Background Many people with mental illness experience stigma that has impacted their lives. In this study, we validated the Inventory of Stigmatizing Experiences (ISE) as a tool to help quantify the stigma experienced by patients with bipolar disorder and its impact on their lives. The ISE has two components, ie, the Stigma Experiences Scale (SES) and the Stigma Impact Scale (SIS), which were administered to a population of Argentinean patients with bipolar disorder. We characterized the differences between these two populations using the SES and SIS. Finally, we compared SES and SIS scores with those in a population of Canadian patients with bipolar disorder. Methods: The SES and SIS scales were administered to tertiary care patients with bipolar I and II disorder in Argentina (n = 178) and Canada (n = 214). Results: In this study, we validated both SES (Kuder-Richardson coefficient of reliability, 0.78) and SIS (Cronbach’s alpha, 0.91) scales in a population of Argentinean patients with bipolar disorder. There were no significant differences in stigma between patients with bipolar I or II disorder on SES or SIS. However, over 50% of all respondents believed that the average person is afraid of those with mental illnesses, that stigma associated with mental illness has affected their quality of life, and that their self-esteem has suffered due to stigma. In comparison with the Canadian population, Argentinean participants scored lower on both the SES and SIS, which may be due to cultural differences or to differences in population characteristics. Conclusion: Stigma associated with mental illness is serious and pervasive. If we are to find successful strategies to mitigate stigma, it is first important to understand how patients perceive such stigma. The ISE is a valuable tool which allows us to do this with high reliability among cultures. PMID:23355778

    In recent years, investigators have begun to consider the possibility of explaining the physiopathology of bipolar disorder from a neuroprogressive perspective. The evidence that supports the feasibility of such an approach is varied, and arises from neuroimaging studies, batteries of neurocognitive evaluations, and tests to identify the specific biomarkers of the disorder. The present article seeks to perform a review of the research that investigates the cognitive deficits in bipolar disorder. A bibliographic revision was performed of articles published between 1990 and 2015. Levels of cognitive performance were explored in both cross-sectional and longitudinal studies. The compiled studies signal the presence of altered cognitive function, even during periods of euthymia. However, there are contradictory results as to whether bipolar disorder presents a degenerative course. New lines of investigation suggest that only a percentage of individuals with bipolar disorder are affected in a progressive manner. It is of paramount importance to perform new longitudinal studies in high-risk populations, so as to validate or refute a neuroprogressive model of cognitive deficits in patients with bipolar disorder.

    Summary Partly due to the overlap of symptom groupings in DSM, psychiatric comorbidity is extremely common. One of the most common and difficult to manage comorbid conditions is the co-occurrence of bipolar disorder (BD) and obsessive compulsive disorder (OCD). However, the key nosological question about this condition – whether they are two distinct disorders or a subtype of one of the disorders – remains unresolved. In order to help address this unanswered question, we updated our recent systematic review, searching the electronic databases MEDLINE, Embase, and PsycINFO to specifically investigate the heredity in BD-OCD patients. We identified a total of 8 relevant papers, the majority of which found that, compared to non-BD-OCD patients, BD-OCD patients were more likely to have a family history for mood disorders and less likely to have a family history for OCD. These results support the view that the majority of cases of comorbid BD-OCD are, in fact, BD cases. If confirmed in larger, more focused studies, this conclusion would have important nosological and clinical implications. PMID:26977128

    Psychiatric patients with bipolar disorder suffer from states of depression and mania, during which a variety of symptoms are present. Current treatments are limited and neurocognitive deficits in particular often remain untreated. Targeted therapies based on the biological mechanisms of bipolar disorder could fill this gap and benefit patients and their families. Developing targeted therapies would benefit from appropriate animal models which are challenging to establish, but remain a vital tool. In this review, we summarize approaches to create a valid model relevant to bipolar disorder. We focus on studies that use translational tests of multivariate exploratory behavior, sensorimotor gating, decision-making under risk, and attentional functioning to discover profiles that are consistent between patients and rodent models. Using this battery of translational tests, similar behavior profiles in bipolar mania patients and mice with reduced dopamine transporter activity have been identified. Future investigations should combine other animal models that are biologically relevant to the neuropsychiatric disorder with translational behavioral assessment as outlined here. This methodology can be utilized to develop novel targeted therapies that relieve symptoms for more patients without common side effects caused by current treatments. PMID:26297513

The aim of this study is to assess whether biochemical changes in the serum of patients induces neurotoxicity in neuronal cell cultures. Methods: We challenged the retinoic acid-differentiated human neuroblastoma SH-SY5Y cells with the serum of BD patients at early and late stages of illness and assessed neurite density and cell viability as neurotoxic endpoints. Results: Decreased neurite density was found in neurons treated with the serum of patients, mostly patients at late stages of illness. Also, neurons challenged with the serum of late-stage patients showed a significant decrease in cell viability. Conclusions: Our findings showed that the serum of patients with bipolar disorder induced a decrease in neurite density and cell viability in neuronal cultures. PMID:27207915

    Thyroid disfunction affects negatively emotional stability and worsens the clinical course of bipolar affective disorder. The main stabilizer used in this illness, lithium carbonate has numerous effects on the physiology of the thyroid, with the most significant being the inhibition of thyroid hormone release that may occur at therapeutic levels. These dysfunctions have also been reported most frequently in bipolar patients not undergoing treatment with lithium, and was not completely explained by the effects of this drug. Apart from the numerous medical complications and mood disturbances, the cognitive or perceptual system may also be affected. In fact, the presence of thyroid disease increases the rates of obsessive compulsive disorder, phobias, panic disorder, major depressive disorder, cyclothymia, or bipolar disorder. In severe cases of hypothyroidism, the clinical symptoms and signs can be similar to a melancholic depression or dementia. It is therefore important to know well all these possible complications in daily clinical practice. This review will cover the main thyroid dysfunctions present in bipolar patients, whether ot not produced by treatment with lithium carbonate, and will provide a series of recommendations for clinical management.

    Abstract Purpose This review article provides an overview of the frequency, burden of illness, diagnosis, and treatment of bipolar disorder (BD) from the perspective of the advanced practice nurses (APNs). Data sources PubMed searches were conducted using the following keywords: “bipolar disorder and primary care,” restricted to dates 2000 to present; “bipolar disorder and nurse practitioner”; and “bipolar disorder and clinical nurse specialist.” Selected articles were relevant to adult outpatient care in the United States, with a prioritization of articles written by APNs or published in nursing journals. Conclusions BD has a substantial lifetime prevalence in the population at 4%. Because the manic or depressive symptoms of BD tend to be severe and recurrent over a patient's lifetime, the condition is associated with significant burden to the individual, caregivers, and society. Clinician awareness that BD may be present increases the likelihood of successful recognition and appropriate treatment. A number of pharmacological and nonpharmacological treatments are available for acute and maintenance treatments, with the prospect of achieving reduced symptom burden and increased functioning for many patients. Implications for practice Awareness of the disease burden, diagnostic issues, and management choices in BD has the potential to enhance outcome in substantial proportions of patients. PMID:26172568

    Background and Aims Behavioral addictions and bipolar disorders have a certain probability of co-occurrence. While the presence of a manic episode has been defined as an exclusion criterion for gambling disorder, no such exclusion has been formulated for Internet addiction. Methods A clinical sample of 368 treatment seekers presenting with excessive to addictive Internet use was screened for bipolar spectrum disorders using the Mood Disorder Questionnaire. Psychopathology was assessed by the Symptom Checklist 90R and a clinical interview was administered to screen for comorbid disorders. Results Comorbid bipolar disorders were more frequent in patients meeting criteria for Internet addiction (30.9%) than among the excessive users (5.6%). This subgroup showed heightened psychopathological symptoms, including substance use disorders, affective disorders and personality disorders. Further differences were found regarding frequency of Internet use regarding social networking sites and online-pornography. Discussion Patients with Internet addiction have a heightened probability for meeting criteria of bipolar disorders. It is not possible to draw conclusions regarding the direction of this association but it is recommended to implement screening for bipolar disorders in patients presenting with Internet addiction. Conclusion Similar to gambling disorder, it might prove necessary to subsume bipolar disorders as an exclusion criterion for the future criteria of Internet addiction. PMID:26132914

    Background: Subjective experience means subtle, not yet psychotic abnormalities of experience that might be present during remitted phase and also in prodromal phase of schizophrenia and might be accurately efficient in identifying individuals at risk of eminent psychosis (Parnas et al., 2003). Apart from schizophrenic patients, bipolar patients also experience certain subjective symptoms in their euthymic state. They often experience subtle cognitive impairment and functional disturbances during their euthymic states. These subjective experiences may be related to distorted cognitive functions in these patients. These experiences include a great variety of cognitive dysfunction complaints about attention, perception, memory, thinking, language, movement, and emotion. Objective: To measure the experience of subjective symptoms and compare them between euthymic bipolar and remitted schizophrenia patients. Materials and Methods: Thirty euthymic bipolar patients and 30 remitted schizophrenia patients as per International Classification of Diseases Tenth Revision were selected for the purpose of the study. At first, sociodemographic data were collected. And then, the patients were assessed using the scales; positive and negative syndrome scale, Young Mania Rating Scale, Hamilton Depression Rating Scale, Symptom Checklist-90-Revised, and Frankfurt Complaint Questionnaire-24. Results: Both the groups showed significant differences in terms of subjective symptoms. However, no significant correlation has been found between the objective psychopathology and subjective experience in the two groups. Conclusion: It can be suggested that the patients with schizophrenia show significantly higher subjective experience when compared with the patients of bipolar disorder. PMID:27114621

    Introduction Cognitive impairment in the euthymic phase is a well-established finding in bipolar disorder. However, its brain structural and/or functional correlates are uncertain. Methods Thirty-three euthymic bipolar patients with preserved memory and executive function and 28 euthymic bipolar patients with significant memory and/or executive impairment, as defined using two test batteries, the Rivermead Behavioural Memory Test (RBMT) and the Behavioural Assessment of the Dysexecutive Syndrome (BADS), plus 28 healthy controls underwent structural MRI using voxel-based morphometry (VBM). Twenty-seven of the cognitively preserved patients, 23 of the cognitively impaired patients and 28 controls also underwent fMRI during performance of the n-back working memory task. Results No clusters of grey or white matter volume difference were found between the two patient groups. During n-back performance, the cognitively impaired patients showed hypoactivation compared to the cognitively preserved patients in a circumscribed region in the right dorsolateral prefrontal cortex. Both patient groups showed failure of de-activation in the medial frontal cortex compared to the healthy controls. Conclusions Cognitive impairment in euthymic bipolar patients appears from this study to be unrelated to structural brain abnormality, but there was some evidence for an association with altered prefrontal function.

    Schizophrenia patients experience cognitive control disturbances, manifest in altered neural signatures during action monitoring. It remains unclear whether error- and conflict-monitoring disturbances co-occur, and whether they are observed in recent-onset psychosis patients with schizophrenia or bipolar disorder. We tested electrophysiological measures of action monitoring in these patients. 73 schizophrenia patients (SZ), 26 bipolar disorder type I patients (BP), each within one year of psychosis onset, and 54 healthy control subjects (HC) underwent EEG during Stroop task performance. In the trial-averaged EEG at three midline scalp electrodes, the error-related negativity (ERN), error positivity (Pe) and conflict-related N450 were measured. Compared to HC, 1) SZ exhibited an attenuated ERN and N450, and Pe unchanged, and 2) BP exhibited an attenuated ERN but normal Pe and N450. Between patient groups, SZ showed an attenuated N450; ERN and Pe were not significantly different. A small (n=10) SZ subgroup that was not receiving antipsychotic medication showed normal ERPs. Altered error- and conflict-monitoring occur together in first-episode schizophrenia patients, and these measures are comparable in patients with first-episode bipolar disorder. Antipsychotic medication may be associated with altered measures of error-monitoring in schizophrenia. PMID:24314907

    Risk-taking behavior and impulsivity are core features of bipolar disorder. Whether they are part of the inherited aspect of the illness is not clear. We aimed to evaluate risk-taking behavior as a potential endophenotype for bipolar disorders, and its relationship with impulsivity and illness features. The Balloon Analogue Risk Task (BART) and Barratt Impulsiveness Scale-11 (BIS-11) were used to assess risk-taking behavior and impulsivity respectively in 30 euthymic bipolar I patients (BD), their 25 asymptomatic first-degree relatives (BD-R), and 30 healthy controls (HC). The primary BART outcome measure was the behavioral adjustment score (number of pumps after trials where the balloon did not pop minus the number of pumps after trials where the balloon popped). BD (p < .001) and BD-R (p = .001) had similar and significantly lower adjustment scores than HC. Only BD scored significantly higher on BIS-11 total (p = .01) and motor (p = .04) subscales than HC. Neither the BART, nor impulsivity scores associated with illness features. A limitation of this study is medicated patients and a heterogeneous BD-R were included. Riskiness may be a candidate endophenotype for bipolar disorder as it appears independently from illness features, presents similarly in BD and BD-R groups and differs from impulsivity.

    Affective temperament has been suggested as a potential mediator of the effect between genetic predisposition and neurocognitive functioning. As such, this report seeks to assess the extent of the correlation between affective temperament and cognitive function in a group of bipolar II subjects. 46 bipolar II outpatients [mean age 41.4 years (SD 18.2); female 58.9%] and 46 healthy controls [mean age 35.1 years (SD 18); female 56.5%] were evaluated with regard to their demographic and clinical characteristics, affective temperament, and neurocognitive performance. Crude bivariate correlation analyses and multiple linear regression models were constructed between five affective temperament subscales and eight neurocognitive domains. Significant correlations were identified in bipolar patients between hyperthymic temperament and verbal memory and premorbid IQ; cyclothymic temperament and attention; and irritable temperament, attention, and verbal fluency. In adjusting for potential confounders of the relationship between temperament and cognitive function, the strongest mediating factors among the euthymic bipolar patients were found to be residual manic and depressive symptoms. It is therefore concluded that affective temperaments may partially influence the neurocognitive performance of both healthy controls and euthymic patients with bipolar disorder type II in several specific domains.

    AIM To study if anxiety, depression and experience of stress are associated with gastrointestinal (GI) symptoms in patients with bipolar disorder. METHODS A total of 136 patients with bipolar disorder (mean age 49.9 years; 61% women) and 136 controls from the general population (mean age 51.0 years; 60% women) were included in the study. GI symptoms were assessed with The Gastrointestinal Symptom Rating Scale-irritable bowel syndrome (GSRS-IBS), level of anxiety and depression with The Hospital Anxiety and Depression Scale (HADS) and stress-proneness with Perceived Stress Questionnaire. Over a ten year period, all visits in primary care were retrospectively recorded in order to identify functional GI disorders. RESULTS In subjects with low total HADS-score, there were no significant differences in GI-symptoms between patients and controls (GSRS-IBS 7.0 vs 6.5, P = 0.513). In the patients with bipolar disorder there were significant correlations between all GSRS and HADS subscores for all symptom clusters except for “constipation” and “reflux”. Factors associated to GI symptoms in the patient group were female sex (adjusted OR = 2.37, 95%CI: 1.07-5.24) and high HADS-Depression score (adjusted OR = 3.64, 95%CI: 1.07-12.4). These patients had also significantly more visits for IBS than patients with low HADS-Depression scores (29% vs 8%, P = 0.008). However, there was no significant differences in consulting behaviour for functional GI disorders between patients and controls (25% vs 17%, P = 0.108). CONCLUSION Female patients and patients with high HADS depression score reported significantly more GI symptoms, whereas patients with low HADS scores did not differ from control subjects.

    Background In a recent exploratory randomized controlled trial, an online psychoeducation intervention for bipolar disorder has been found to be feasible and acceptable to patients and may positively impact on their self-management behaviors and quality of life. Objective The objective of the study was to investigate how these patients contribute to an online forum for bipolar disorder and the issues relevant for them. Methods Participants in the intervention arm of the Bipolar Interactive PsychoEDucation (“BIPED”) trial were invited to contribute to the Beating Bipolar forum alongside receiving interactive online psychoeducation modules. Within this virtual participant observation study, forum posts were analyzed using thematic analysis, incorporating aspects of discourse analysis. Results The key themes which arose from the forum posts included: medication, employment, stigma, social support, coping strategies, insight and acceptance, the life chart, and negative experiences of health care. Participants frequently provided personal narratives relating to their history of bipolar disorder, life experiences, and backgrounds, which often contained emotive language and humor. They regularly sought and offered advice, and expressed encouragement and empathy. The forum would have benefitted from more users to offer a greater support network with more diverse views and experiences. Conclusions Online forums are inexpensive to provide and may offer peer support and the opportunity for patients to share their experiences and explore issues related to their illness anonymously. Future research should focus on how to enhance patient engagement with online health care forums.

    Semantic and verbal fluency tasks are widely used as a measure of frontal capacities. It has been well described in literature that patients affected by schizophrenic and bipolar disorders present a worse execution in these tasks. Some authors have also noted the importance of educational years. Our objective is to analyze whether the effect of cognitive malfunction caused by apathology is superior to the expected effect of years of education in phonemic verbal fluency (PVF) and semantic verbal fluency (SVF) task execution. A total of 62 individuals took part in this study, out of which 23 were patients with schizophrenic paranoid disorder, 11 suffered from bipolar disorder with psychotic symptomatology, 13 suffered from bipolar disorder without psychotic symptomatology, and 15 participants were nonpathological individuals. All participants were evaluated with the PVF and SVF tests (animals and tools). The performance/execution results were analyzed with a mixed-model ANCOVA, with educational years as a covariable. The effect of education seems to be more determined by PVF FAS tests than by SVF. With PVF FAS tasks, the expected effect of pathology disappears when the covariable EDUCATION is introduced. With SVF tasks, the effect continues to be significant, even though the EDUACTION covariable dims such effect. These results suggest that SVF tests (animals category) are better evaluation tools as they are less dependent on the patients' education than PVF FAS tests.

    It is well recognized that mood disorders and epilepsy commonly co-occur. Despite this, our knowledge regarding the relationship between epilepsy and bipolar disorder is limited. Several shared features between the two disorders, such as their episodic nature and potential to run a chronic course, and the efficacy of some antiepileptic medications in the prophylaxis of both disorders, are often cited as evidence of possible shared underlying pathophysiology. The present paper aims to review the bidirectional associations between epilepsy and bipolar disorder, with a focus on epidemiological links, evidence for shared etiology, and the impact of these disorders on both the individual and wider society. Better recognition and understanding of these two complex disorders, along with an integrated clinical approach, are crucial for improved evaluation and management of comorbid epilepsy and mood disorders.

    Postmortem brain studies have shown abnormal levels of n-3 polyunsaturated fatty acids (PUFAs), especially docosahexaenoic acid, in the frontal cortex (particularly the orbitofrontal cortex) of patients with depression, schizophrenia, or bipolar disorder. However, the results from regions in the frontal cortex other than the orbitofrontal cortex are inconsistent. In this study we investigated whether patients with schizophrenia, bipolar disorder, or major depressive disorder have abnormalities in PUFA levels in the prefrontal cortex [Brodmann area (BA) 8]. In postmortem studies, fatty acids in the phospholipids of the prefrontal cortex (BA8) were evaluated by thin layer chromatography and gas chromatography. Specimens were evaluated for patients with schizophrenia (n=15), bipolar disorder (n=15), or major depressive disorder (n=15) and compared with unaffected controls (n=15). In contrast to previous studies, we found no significant differences in the levels of PUFAs or other fatty acids in the prefrontal cortex (BA8) between patients and controls. Subanalysis by sex also showed no significant differences. No significant differences were found in any individual fatty acids between suicide and non-suicide cases. These psychiatric disorders might be characterized by very specific fatty acid compositions in certain areas of the brain, and BA8 might not be involved in abnormalities of PUFA metabolism.

    Bipolar disorder is a frequent disorder in the elderly, with a prevalence of 0.1 a 0.4%; a 10% of bipolar patients have mania onset after 50 years old. It has in ageing a more heterogeneous clinical presentation. The manic episodes are less severe, mixed depression is common, as well as confusion and cognitive impairment. A first manic episode in ageing can be secondary to medical illness. Treatment for bipolar disorder in ageing is similar to treatment for young patients. The differences are due to pharmacocinetic changes because of the age, with the comorbidity and with the etiology, if it is a secondary mania. Lithium can be the first choice for treating mania in patients with antecedent of good response and have tolerance to adverse effects, but because of its toxicity and secondary effects other possibilities may be considered: divalproate, cabamazepine, antipsychotics. There are some little studies that show lamotrigine efficacy in bipolar depression in elderly. We need more specific studies about bipolar disorder treatment in aging.

    2013-01-01

    Background Evidence suggests that neurotropic infectious agents might be involved in bipolar disorder. So far, few have been written for the association between parasitic infection and bipolar disorder. Filariasis is a parasitic disease acting ruthlessly via mosquitos and affecting more than 120 million people worldwide. We present here, to our knowledge, the first description of a filariasis infected manic bipolar disorder patient fully improved in terms of psychiatric symptoms by anti-heminthic treatment. Case presentation The patient is a 31 years-old man native of Congo. At inclusion, he presented a severe manic episode with dangerous behaviour unresolved by classic treatments. A diagnosis of filariasis bancrofti infection was made after the discovery of a systemic hypereosinophilia. Therefore, a bi-therapy of anthelmintics was conducted allowing a successful improvement with clear reduction of agitation and aggressive behaviours that could not be attributed to a modification of psychotropic treatments or filarial encephalopathy or acute disseminated encephalomyelitis. Conclusion The ineffectiveness of psychotropic treatment of a manic episode requires the evaluation of co-morbid medical conditions such as infections which can interfere with adequate mood stabilizing medication. Filariasis by inducing chronic inflammation and immunopathologic reactions seems to play a major role in infected affective disorders patients by changing levels of cytokines of the Th1 system or indirectly damaging the brain tissue. The beneficial combination of antihelmintics and mood stabilizers, in this case, could be explained by the potential of such association to downregulate neuroinflammation and excitotoxicity processes. Altogether, these data pinpoint the requirement to explore the parasitic infectious status in case of bipolar disorder patients resistant to classic treatments and originating or living in endemic geographical areas.

    It is clinically important to recognize both bipolar disorder and borderline personality disorder (BPD) in patients seeking treatment for depression, and it is important to distinguish between the two. Research considering whether BPD should be considered part of a bipolar spectrum reaches differing conclusions. We reviewed the most studied question on the relationship between BPD and bipolar disorder: their diagnostic concordance. Across studies, approximately 10% of patients with BPD had bipolar I disorder and another 10% had bipolar II disorder. Likewise, approximately 20% of bipolar II patients were diagnosed with BPD, though only 10% of bipolar I patients were diagnosed with BPD. While the comorbidity rates are substantial, each disorder is nontheless diagnosed in the absence of the other in the vast majority of cases (80% to 90%). In studies examining personality disorders broadly, other personality disorders were more commonly diagnosed in bipolar patients than was BPD. Likewise, the converse is also true: other axis I disorders such as major depression, substance abuse, and post-traumatic stress disorder are also more commonly diagnosed in patients with BPD than is bipolar disorder. These findings challenge the notion that BPD is part of the bipolar spectrum.

    The prodromal phase is generally described as a subsyndromal stage preceding the disease onset. The characterization of such phase found its main purpose in secondary prevention. Up to now, clinical research relating to this topic in mental health has primarily focus on schizophrenic disorders. Over the last years, some studies have applied similar methods in order to characterize a preclinical phase in bipolar disorders. In spite of the fact that this strategy appears less adequate in bipolar disorders, these studies have demonstrated the existence of prodromal signs in a majority of patients. However, these features appear for the moment neither sufficiently characteristic, nor sufficiently specific to allow the construction of suitable assessment instruments, or to suggest precise guidelines in the management of these subjects. Also, these prodromal features show considerable overlap with other psychiatric disorders, especially attention-deficit hyperactivity disorder (ADHD) and schizophrenia Interestingly, a limited number of studies have looked at the number of patients considered in a prodromal phase of schizophrenia which later developed a bipolar disorder and reported substantial proportions of subjects in this case, further highlighting the obvious bias in favor of schizophrenia in the actual prevention politics. In order to identify potential candidates at a prodromal phase of bipolar disorders that could benefit from early intervention, studies have relied on both high genetic risk and symptoms at the boundary of the actual classification. However, even within such approach, pharmacological treatments have not proven obvious advantage in terms of prevention. It is suggested that adopting a more longitudinal vision of the disease and, given the mean age of onset of bipolar disorder and a fortiori of its prodromal phase, a more developmental perspective of individuals, could help lowering the confusion in this field ; Also, given the considerable overlap

    Patients with Bipolar Disorder (BD) have high rates of suicide compared to the general population. The present study investigates the predictive power of baseline clinical, psychological and environmental characteristics as risk factors of prospective suicide events (attempts and completions). Data was collected from the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) study. 3083 bipolar patients were included in this report, among these 140 (4.6%) had a suicide event (8 died by suicide and 132 attempted suicide). Evaluation and assessment forms were used to collect clinical, psychological and socio-demographic information. Chi-square and independent t-tests were used to evaluate baseline characteristics. Potential prospective predictors were selected on the basis of prior literature and using a screening analysis of all risk factors that were associated with a history of suicide attempt at baseline and were tested using a Cox regression analysis. The strongest predictor of a suicide event was a history of suicide attempt (hazard ratio = 2.60, p-value < 0.001) in line with prior literature. Additional predictors were: younger age, a high total score on the personality disorder questionnaire and a high percentage of days spent depressed in the year prior to study entry. In conclusion, the present findings may help clinicians to identify patients at high risk for suicidal behavior upon presentation for treatment.

    Objective Several studies have reported higher prevalence of obesity in patients suffering from bipolar disorder (BD). To study the relation of elevated body mass index (BMI) in patients with BD more closely, we investigated differences in sociodemographic, clinical, and medical characteristics with respect to BMI, with the hypothesis that BMI is related to prognosis and outcome. Methods We measured the BMI of 276 subjects of a tertiary care sample from the Maritime Bipolar Registry. Subjects were 16 to 83 years old, with psychiatric diagnoses of bipolar I disorder (n = 186), bipolar II disorder (n = 85), and BD not otherwise specified (n = 5). The registry included basic demographic data and details of the clinical presentation. We first examined the variables showing a significant association with BMI; subsequently, we modeled the relationship between BMI and psychiatric outcome using structural equation analysis. Results The prevalence of obesity in our sample was 39.1%. We found higher BMI in subjects with a chronic course (p < 0.001) and longer duration of illness (p = 0.02), lower scores on the Global Assessment of Functioning Scale (p = 0.02), and on disability (p = 0.002). Overweight patients had more frequent comorbid subthreshold social (p = 0.02) and generalized anxiety disorders (p = 0.05), diabetes mellitus type II (p < 0.001), and hypertension (p = 0.001). Subjects who achieved complete remission of symptoms on lithium showed significantly lower BMI (p = 0.01). Conclusions Our findings suggest that BMI is associated with the prognosis and outcome of BD. Whether this association is causal remains to be determined. PMID:19689507

    Abnormalities of the anterior cingulate cortex (ACC) are thought to be involved in the pathophysiology of bipolar disorder, but structural Magnetic Resonance Imaging (MRI) studies have reported variable findings. Reasons for this include a failure to consider variability in regional cortical folding patterns and a reliance on relatively coarse measures (e.g., volume) to index anatomical change. We sought to overcome these limitations by combining a novel protocol for parcellating the ACC and adjacent paracingulate cortex (PaC) that accounts for inter-individual variations in sulcal and gyral morphology with a cortical surface-based approach that allowed calculation of regional grey matter volume, surface area and cortical thickness in 24 patients with bipolar I disorder and 24 matched controls. No changes in grey matter volume or surface area were identified in any region, but patients did show significant reductions in cortical thickness in the left rostral PaC and right dorsal PaC that were not attributable to group differences in cortical folding patterns. These findings suggest that bipolar disorder is associated with more pronounced changes in the PaC, and that reliance on volumetric measures alone may obscure more subtle differences. PMID:18207705

    The results of mortality studies have indicated that medical conditions, such as cardiovascular disease, obesity and diabetes are the most important causes of mortality among patients with bipolar disorder. The reasons for the increased incidence and mortality are not fully understood. Oxidative stress and an inadequate antioxidative system might be one missing link and could also help to further elucidate the pathophysiological basis of bipolar disorder. This article provides a comprehensive review of oxidative stress in general and about the existing data for bipolar disorder. In addition information is given about possible therapeutic strategies to reduce oxidative stress and the use in bipolar disorder. PMID:24441847

    In a large Scottish pedigree, a balanced translocation t (1;11)(q42.1;q14.3) disrupting the DISC1 and DISC2 genes segregates with major mental illness, including schizophrenia and depression. A frame-shift carboxyl-terminal deletion was reported in DISC1 in an American family with schizophrenia, but subsequently found in two controls. Herein, we test one hypothesis utilizing a large scale case-control mutation analysis: uncommon DISC1 variants are associated with high risk for bipolar spectrum disorder. We have analyzed the regions of likely functional significance in the DISC1 gene in 504 patients with bipolar spectrum disorder and 576 ethnically similar controls. Five patients were heterozygous for ultra-rare protein structural variants not found in the 576 controls (p=0.02, one-sided Fisher's exact test) and shown to be ultra-rare by their absence in a pool of 10,000 control alleles. In our sample, ultra-rare (private) protein structural variants in DISC1 are associated with an estimated attributable risk of about 0.5% in bipolar spectrum disorder. These data are consistent with: (i) the high frequency of depression in the large Scottish family with a translocation disrupting DISC1; (ii) linkage disequilibrium analysis demonstrating haplotypes associated with relatively small increases in risk for bipolar disorder (<3-fold odds ratio). The data illustrate how low/moderate risk haplotypes that might be found by the HapMap project can be followed up by resequencing to identify protein structural variants with high risk, low frequency and of potential clinical utility.

    Bipolar disorders are often associated with cognitive deficits which have an influence on social functioning and the course of the illness. These deficits have an impact on occupational ability and social integration. To date, specific cognitive domains have been found which characterize bipolar affective disorders. However, there is evidence of stable and lasting cognitive impairment in all phases of the disorder, including the remission phase, in the following domains: sustained attention, memory and executive functions (e.g. cognitive flexibility and problem solving). Although their cognitive deficits are comparable the deficits in patients with schizophrenia are more severe than those with bipolar disorder. Recent brain imaging findings indicate structural and functional abnormalities in the cortical and limbic networks of the brain in patients with bipolar disorder compared to healthy controls. Mood stabilizer and atypical antipsychotics may reduce cognitive deficits in certain domains (e.g. executive functions and word fluency) and may have a positive effect on quality of life and social functioning.

    We review recent developments in the acute and long-term treatment of bipolar disorder and identify promising future routes to therapeutic innovation. Overall, advances in drug treatment remain quite modest. Antipsychotic drugs are effective in the acute treatment of mania; their efficacy in the treatment of depression is variable with the clearest evidence for quetiapine. Despite their widespread use, considerable uncertainty and controversy remains about the use of antidepressant drugs in the management of depressive episodes. Lithium has the strongest evidence for long-term relapse prevention; the evidence for anticonvulsants such as divalproex and lamotrigine is less robust and there is much uncertainty about the longer term benefits of antipsychotics. Substantial progress has been made in the development and assessment of adjunctive psychosocial interventions. Long-term maintenance and possibly acute stabilisation of depression can be enhanced by the combination of psychosocial treatments with drugs. The development of future treatments should consider both the neurobiological and psychosocial mechanisms underlying the disorder. We should continue to repurpose treatments and to recognise the role of serendipity. We should also investigate optimum combinations of pharmacological and psychotherapeutic treatments at different stages of the illness. Clarification of the mechanisms by which different treatments affect sleep and circadian rhythms and their relation with daily mood fluctuations is likely to help with the treatment selection for individual patients. To be economically viable, existing psychotherapy protocols need to be made briefer and more efficient for improved scalability and sustainability in widespread implementation. PMID:23663953

    Mixed manic/depressive episodes in patients with bipolar disorder are underdiagnosed because of restrictive diagnostic criteria. Using the broader definition of a mixed episode represented by the Cincinnati criteria, we reevaluated the medical records of patients with bipolar disorder hospitalized for a manic episode. We also examined the predictive power of previously unrecognized depressive symptoms. Of 520 inpatients with mania, we retrospectively diagnosed 59 (11.3%) as having a probable mixed episode. Compared with the patients with pure mania, the patients with mixed episodes were more likely to have a family history of psychiatric illness, comorbid personality disorder, and a history of suicide attempts. Binary logistic regression revealed that loss of interest, loss of energy, feelings of worthlessness, and feelings of helplessness had good positive predictive value (>0.7) for mixed episodes. Accurate diagnosis of mixed episodes may require a broadening of diagnostic criteria and emphasis on symptoms such as loss of interest, loss of energy, and feelings of worthlessness and helplessness.

    The relationship between creativity and bipolar disorder has been an intriguing topic since ancient times. Early studies focused on describing characteristics of creative people. From the last quarter of the twentieth century, researchers began to focus on the relationship between mood disorders and creativity. Initially, the studies were based on biographical texts and the obtained results indicated a relationship between these two concepts. The limitations of the retrospective studies led the researchers to develop systematic investigations into this area. The systematic studies that have focused on artistic creativity have examined both the prevalence of mood disorders and the creative process. In addition, a group of researchers addressed the relationship in terms of affective temperaments. Through the end of the 90's, the scope of creativity was widened and the notion of everyday creativity was proposed. The emergence of this notion led researchers to investigate the associations of the creative process in ordinary (non-artist) individuals. In this review, the descriptions of creativity and creative process are mentioned. Also, the creative process is addressed with regards to bipolar disorder. Then, the relationship between creativity and bipolar disorder are evaluated in terms of aforementioned studies (biographical, systematic, psychobiographical, affective temperaments). In addition, a new model, the "Shared Vulnerability Model" which was developed to explain the relationship between creativity and psychopathology is introduced. Finally, the methodological limitations and the suggestions for resolving these limitations are included.

    Fractal geometry can be used to analyze shape and patterns in brain images. With this study we use fractals to analyze T1 data of patients affected by schizophrenia or bipolar disorder, with the aim of distinguishing between healthy and pathological brains using the complexity of brain structure, in particular of grey matter, as a marker of disease. 39 healthy volunteers, 25 subjects affected by schizophrenia and 11 patients affected by bipolar disorder underwent an MRI session. We evaluated fractal dimension of the brain cortex and its substructures, calculated with an algorithm based on the box-count algorithm. We modified this algorithm, with the aim of avoiding the segmentation processing step and using all the information stored in the image grey levels. Moreover, to increase sensitivity to local structural changes, we computed a value of fractal dimension for each slice of the brain or of the particular structure. To have reference values in comparing healthy subjects with patients, we built a template by averaging fractal dimension values of the healthy volunteers data. Standard deviation was evaluated and used to create a confidence interval. We also performed a slice by slice t-test to assess the difference at slice level between the three groups. Consistent average fractal dimension values were found across all the structures in healthy controls, while in the pathological groups we found consistent differences, indicating a change in brain and structures complexity induced by these disorders.

    Bipolar disorder is a high-risk condition during pregnancy. In women receiving prenatal care, this study addresses the proportion screening positive for bipolar disorder with or without also screening positive for depression. This is a pilot study using chart abstraction of Edinburgh Postnatal Depression Scale (EPDS) and Mood Disorder Questionnaire (MDQ) scores from patients' initial prenatal visits. Among 342 participants, 289 (87.1 %) completed the EPDS, 277 (81.0 %) completed the MDQ, and 274 (80.1 %) completed both. Among EPDS screens, 49 (16.4 %) were positive. Among MDQ screens, 14 (5.1 %) were positive. Nine (21.4 %) of the 42 participants with a positive EPDS also had a positive MDQ. Of the 14 patients with a positive MDQ, five (35.7 %) had a negative EPDS. The prevalence of positive screens for bipolar disorder in an obstetric population is similar to gestational diabetes and hypertension, which are screened for routinely. Without screening for bipolar disorder, there is a high risk of misclassifying bipolar depression as unipolar depression. If only women with current depressive symptoms are screened for bipolar disorder, approximately one third of bipolar disorder cases would be missed. If replicated, these findings support simultaneous screening for both depression and bipolar disorder during pregnancy.

    We use limit cycle oscillators to model bipolar II disorder, which is characterized by alternating hypomanic and depressive episodes and afflicts about 1% of the United States adult population. We consider two non-linear oscillator models of a single bipolar patient. In both frameworks, we begin with an untreated individual and examine the mathematical effects and resulting biological consequences of treatment. We also briefly consider the dynamics of interacting bipolar II individuals using weakly-coupled, weakly-damped harmonic oscillators. We discuss how the proposed models can be used as a framework for refined models that incorporate additional biological data. We conclude with a discussion of possible generalizations of our work, as there are several biologically-motivated extensions that can be readily incorporated into the series of models presented here.

    Today's health care is difficult to imagine without the possibility to objectively measure various physiological parameters related to patients' symptoms (from temperature through blood pressure to complex tomographic procedures). Psychiatric care remains a notable exception that heavily relies on patient interviews and self-assessment. This is due to the fact that mental illnesses manifest themselves mainly in the way patients behave throughout their daily life and, until recently there were no "behavior measurement devices." This is now changing with the progress in wearable activity recognition and sensor enabled smartphones. In this paper, we introduce a system, which, based on smartphone-sensing is able to recognize depressive and manic states and detect state changes of patients suffering from bipolar disorder. Drawing upon a real-life dataset of ten patients, recorded over a time period of 12 weeks (in total over 800 days of data tracing 17 state changes) by four different sensing modalities, we could extract features corresponding to all disease-relevant aspects in behavior. Using these features, we gain recognition accuracies of 76% by fusing all sensor modalities and state change detection precision and recall of over 97%. This paper furthermore outlines the applicability of this system in the physician-patient relations in order to facilitate the life and treatment of bipolar patients.

    Background Bipolar disorder (BD) is a common chronic psychiatric disorder mainly characterized by episodes of mania, hypomania and depression. The disorder is associated with cognitive impairments and structural brain abnormalities, such as lower cortical volumes in primarily frontal brain regions than healthy controls. Although bipolar disorder types I (BDI) and II (BDII) exhibit different symptoms and severity, previous studies have focused on BDI. Furthermore, the most frequently investigated measure in this population is cortical volume. The aim of our study was to investigate abnormalities in patients with BDI and BDII by simultaneously analyzing cortical volume, thickness and surface area, which yields more information about disease- and symptom-related neurobiology. Methods We used MRI to measure cortical volume, thickness and area in patients with BDI and BDII as well as in healthy controls. The large study cohort enabled us to adjust for important confounding factors. Results We included 81 patients with BDI, 59 with BDII and 85 controls in our analyses. Cortical volume, thickness and surface area abnormalities were present in frontal, temporal and medial occipital regions in patients with BD. Lithium and antiepileptic drug use had an effect on the observed differences in medial occipital regions. Patients with the subtypes BDI and BDII displayed common cortical abnormalities, such as lower volume, thickness and surface area than healthy controls in frontal brain regions but differed in temporal and medial prefrontal regions, where only those with BDI had abnormally low cortical volume and thickness. Limitations The group differences can be explained by progressive changes, but also by premorbid conditions. They could also have been influenced by unknown factors, such as social, environmental or genetic factors. Conclusion Our findings suggest diagnosis-related neurobiological differences between the BD subtypes, which could explain distinct symptoms and

    Patients with bipolar disorder (BD) are at an increased risk of attempted and completed suicide. To elucidate the beliefs and assumptions associated with suicidality in BD, the present study compared BD patients with and without a history of suicide attempt in terms of early maladaptive schemas (EMSs). The sample consisted of 49 remitted BD patients who completed the Young Schema Questionnaire-Short Version. Information on suicide attempts was obtained through interviews combined with medical records. Compared with BD patients without suicide attempts, the BD patients with suicide attempts scored significantly higher on 3 EMSs: social isolation, practical incompetence, and entitlement. The findings suggest that specific EMSs may be implicated in suicidal behaviors in BD. These results have implications for the assessment and treatment of suicidality in BD. PMID:26919302

    Psychoeducation is a key element in the management of patients with bipolar disorders. The present study explored the perception of patients and family members with respect to group psychoeducation for relatives. Patients (n = 20) and relatives (n = 26) were assessed with questionnaires about perceived benefits and quality of life (median 4 years after participation). A large majority (>80%) of relatives acknowledged benefits with respect to easier detection of the early warning signs of relapse, improved quality of life, feeling more involved, and engaging in higher quality caregiving activities. Patients were less positive in general, but agreed that the program had helped them deal with crises, increased their feeling of being understood by relatives, and promoted positive changes in the family (>60%). Perceived positive changes in the family were associated with higher quality of life for relatives and patients. The present study highlights the importance of communication enhancement in group psychoeducation for relatives. PMID:26313039

    Antipsychotics are the drugs prescribed to treat psychotic disorders; however, patients often fail to adhere to their treatment, and this has a severe negative effect on prognosis in these kinds of illnesses. Among the wide range of risk factors for treatment nonadherence, this systematic review covers those that are most important from the point of view of clinicians and patients and proposes guidelines for addressing them. Analyzing 38 studies conducted in a total of 51,796 patients, including patients with schizophrenia spectrum disorders and bipolar disorder, we found that younger age, substance abuse, poor insight, cognitive impairments, low level of education, minority ethnicity, poor therapeutic alliance, experience of barriers to care, high intensity of delusional symptoms and suspiciousness, and low socioeconomic status are the main risk factors for medication nonadherence in both types of disorder. In the future, prospective studies should be conducted on the use of personalized patient-tailored treatments, taking into account risk factors that may affect each individual, to assess the ability of such approaches to improve adherence and hence prognosis in these patients.

    Bipolar affective disorder in women is a challenging disorder to treat. It is unique in its presentation in women and characterized by later age of onset, seasonality, atypical presentation, and a higher degree of mixed episodes. Medical and psychiatric co-morbidity adversely affects recovery from the bipolar disorder (BD) more often in women. Co-morbidity, particularly thyroid disease, migraine, obesity, and anxiety disorders occur more frequently in women while substance use disorders are more common in men. Treatment of women during pregnancy and lactation is challenging. Pregnancy neither protects nor exacerbates BD, and many women require continuation of medication during the pregnancy. The postpartum period is a time of high risk for onset and recurrence of BD in women. Prophylaxis with mood stabilizers might be needed. Individualized risk/benefits assessments of pregnant and postpartum women with BD are required to promote the health of the women and to avoid or limit exposure of the fetus or infant to potential adverse effects of medication.

    Both schizophrenia and bipolar disorder (BD) have consistently been associated with deficits in facial affect recognition (FAR). These impairments have been related to various aspects of social competence and functioning and are relatively stable over time. However, individuals in remission may outperform patients experiencing an acute phase of the disorders. The present study directly contrasted FAR in symptomatically remitted patients with schizophrenia or BD and healthy volunteers and investigated its relationship with patients' outcomes. Compared to healthy control subjects, schizophrenia patients were impaired in the recognition of angry, disgusted, sad and happy facial expressions, while BD patients showed deficits only in the recognition of disgusted and happy facial expressions. When directly comparing the two patient groups individuals suffering from BD outperformed those with schizophrenia in the recognition of expressions depicting anger. There was no significant association between affect recognition abilities and symptomatic or psychosocial outcomes in schizophrenia patients. Among BD patients, relatively higher depression scores were associated with impairments in both the identification of happy faces and psychosocial functioning. Overall, our findings indicate that during periods of symptomatic remission the recognition of facial affect may be less impaired in patients with BD than in those suffering from schizophrenia. However, in the psychosocial context BD patients seem to be more sensitive to residual symptomatology.

    Tobacco use in mental health in general and bipolar disorder in particular remains disproportionally common, despite declining smoking rates in the community. Furthermore, interactions between tobacco use and mental health have been shown, indicating the outcomes for those with mental health disorders are impacted by tobacco use. Factors need to be explored and addressed to improve outcomes for those with these disorders and target specific interventions for people with psychiatric illness to cease tobacco smoking. In the context of bipolar disorder, this review explores; the effects of tobacco smoking on symptoms, quality of life, suicidal behaviour, the biological interactions between tobacco use and bipolar disorder, the interactions between tobacco smoking and psychiatric medications, rates and factors surrounding tobacco smoking cessation in bipolar disorder and suggests potential directions for research and clinical translation. The importance of this review is to bring together the current understanding of tobacco use in bipolar disorder to highlight the need for specific intervention. PMID:25912533

    Relationships between cortical brain structure and neurocognitive functioning have been reported in schizophrenia, but findings are inconclusive, and only a few studies in bipolar disorder have addressed this issue. This is the first study to directly compare relationships between cortical thickness and surface area with neurocognitive functioning in patients with schizophrenia (n = 117) and bipolar disorder (n = 121) and healthy controls (n = 192). MRI scans were obtained, and regional cortical thickness and surface area measurements were analyzed for relationships with test scores from 6 neurocognitive domains. In the combined sample, cortical thickness in the right rostral anterior cingulate was inversely related to working memory, and cortical surface area in four frontal and temporal regions were positively related to neurocognitive functioning. A positive relationship between left transverse temporal thickness and processing speed was specific to schizophrenia. A negative relationship between right temporal pole thickness and working memory was specific to bipolar disorder. In conclusion, significant cortical structure/function relationships were found in a large sample of healthy controls and patients with schizophrenia or bipolar disorder. The differences that were found between schizophrenia and bipolar may indicate differential relationship patterns in the two disorders, which may be of relevance for understanding the underlying pathophysiology.

    Recent studies have suggested that there are certain pathophysiological relationships between bipolar disorder (BD) and circadian rhythm dysfunction. However, apparently no studies have clarified the prevalence of circadian rhythm sleep-wake disorders (CRSWD) in patients with BD. This study was set out to investigate the prevalence of CRSWD and associated factors in patients with BD. One hundred four euthymic BD outpatients participated in this study. The subjects were asked to answer questionnaires including demographic variables, clinical course of BD, and family history of psychiatric disorders and suicide. Severity of BD was assessed by the Montgomery-Åsberg Depression Rating Scale and Young Mania Rating Scale. CRSWD was diagnosed by clinical interview, together with sleep logs, according to the International Classification of Sleep Disorders, third edition (ICSD-3). Thirty-five subjects (32.4%) met the criteria for CRSWD. The age at the time of investigation and that at the onset of BD were both lower in the CRSWD group than in the non-CRSWD group. The rates of family history of psychiatric disorders and suicide in the CRSWD group were higher than those in the non-CRSWD group. Multiple logistic regression analysis revealed that the presence of CRSWD was significantly associated with younger onset age of BD and family history of suicide. The prevalence of CRSWD could be quite high in BD patients. Younger onset age of BD and family history of suicide were associated with presence of CRSWD in BD patients. PMID:27442503

    Psychiatric patients with bipolar disorder suffer from states of depression and mania, during which a variety of symptoms are present. Current treatments are limited and neurocognitive deficits in particular often remain untreated. Targeted therapies based on the biological mechanisms of bipolar disorder could fill this gap and benefit patients and their families. Developing targeted therapies would benefit from appropriate animal models which are challenging to establish, but remain a vital tool. In this review, we summarize approaches to create a valid model relevant to bipolar disorder. We focus on studies that use translational tests of multivariate exploratory behavior, sensorimotor gating, decision-making under risk, and attentional functioning to discover profiles that are consistent between patients and rodent models. Using this battery of translational tests, similar behavior profiles in bipolar mania patients and mice with reduced dopamine transporter activity have been identified. Future investigations should combine other animal models that are biologically relevant to the neuropsychiatric disorder with translational behavioral assessment as outlined here. This methodology can be utilized to develop novel targeted therapies that relieve symptoms for more patients without common side effects caused by current treatments.

    The self-concept and the partner relationships of patients with bipolar affective disorder in remission were investigated with the Giessen-Test (GT, Beckmann et al. ) comparing the bipolar patients with unipolar depressive patients, a control group of orthopedic patients and the standard sample of the Giessen-Test. The new dimensions "self-esteem" and "near-to-object" were developed by means of the Giessen-Test items. Self-esteem was significantly lower in bipolar patients in remission than in the controls. The bipolar patients also described themselves as "more distant to others" than the controls. Bipolar and unipolar-depressive patients had a similar self-concept and view of their partner relationships. The results underline the importance of the regulation of self-esteem and the interpersonal dimension in the long-term course of bipolar affective disorder. Therapeutic implications are discussed.

    Objective This study aimed to evaluate patients with bipolar I disorder (BD-I) who have mania with depressive symptoms and who meet the new “with mixed features” specifier of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). Method This prospective, multinational, naturalistic study surveyed psychiatrists and their patients with BD-I from October 2013 to March 2014. Eligible patients had BD-I, had a (current) manic episode, and had experienced onset of a manic episode within the previous 3 months. Psychiatrists provided patient information on depressive symptoms (DSM-5 criteria); symptoms of anxiety, irritability, and agitation; suicide attempts; and physician satisfaction with treatment response. Data were stratified according to whether patients met the criteria for the BD-I “with mixed features” specifier of DSM-5 (≥3 depressive symptoms) or not, and characteristics were compared between the two subgroups. Patients also self-reported on depressive symptoms using the Mini-International Neuropsychiatric Interview module questionnaire. Results Overall, 34% of 1,035 patients met the criteria for BD-I “with mixed features,” exhibiting ≥3 depressive symptoms during their current manic episode. This correlated with the matched patient self-reports of depressive symptoms. During their current manic episode, BD-I patients “with mixed features” had more severe symptoms of anxiety, irritability, and agitation (average composite severity score of 4.1 vs 3.4), a higher incidence of suicide attempts (38% vs 9%), and more physician dissatisfaction with treatment response (22% vs 14%), compared to patients with 0–2 depressive symptoms (all P<0.05). Conclusion This study found that patients with BD-I “with mixed features” (ie, ≥3 depressive symptoms during a manic episode), suffered, on average, from a greater burden of disease than patients with pure mania. Improved identification of these patients may help to optimize

Because of the high comorbidity and overlapping symptoms of paediatric bipolar affective disorder and other psychiatric disorders, the major impact of the differential diagnosis has to be stressed. An early diagnosis and the treatment possibilities are discussed.

    Abstract Previous studies have reported that patients with bipolar disorders (BDs) exhibit increased physical comorbidity and psychological distress. Studies have shown that schizophrenia and anxiety increase the risk of peptic ulcer diseases (PUDs). Therefore, we conducted this study to determine the association between these 2 diseases and examine the possible risk factors. We used patients diagnosed with BDs from the Taiwan National Health Insurance Research Database. A comparison cohort comprising patients without BDs was frequency matched by age, sex, and comorbidities, and the occurrence of PUDs was evaluated in both the cohorts. The BD and non-BD cohort consisted of 21,060 patients with BDs and 84,240 frequency-matched patients without BDs, respectively. The incidence of PUDs (hazard ratio, 1.51; 95% confidence interval, 1.43–1.59; P < 0.001) was higher among the patients with BDs than the control patients. Cox models showed that irrespective of comorbidities, BDs were an independent risk factor for PUDs. Patients with BDs exhibit a substantially higher risk for developing PUDs. According to our data, we suggest that, following a diagnosis of BD, practitioners could notice the occurrence of PUD and associated prevention. Further prospective clinical studies investigating the relationship between BDs and PUDs are warranted. PMID:26200637

    NICE recommends that when adults present in primary care with depression, they should be asked about previous periods of overactivity or disinhibited behaviour. If this behaviour lasted for four or more days referral for a specialist mental health assessment should be considered. Although depressive episodes are not necessary for a diagnosis of bipolar disorder, they are common and dominate the lifetime pattern of the condition: 50% of the time is spent in a euthymic (well) state, 38% in a depressed and 12% in a manic state. If there have only been depressive symptoms, it is not possible to exclude bipolar disorder. A diagnosis of bipolar disorder is supported by diagnostic criteria and usually confirmed by a psychiatrist. If the GP suspects mania or severe depression, or if patients are a danger to themselves or others, an urgent referral should be made for a specialist mental health assessment. If a manic episode has been present during the history the diagnosis is bipolar I disorder, while a hypomanic episode is indicative of bipolar disorder. The patient's care plan should include current health status, social situation, social support, co-ordination arrangements with secondary care, details of early warning signs, and the patient's preferred course of action in the event of a clinical relapse. Physical health checks should focus on cardiovascular disease, diabetes, obesity and respiratory disease given the heightened risk for these illnesses in bipolar disorder. PMID:27254890

    Background Medication treatment compliance among bipolar patients is quite widespread. Objectives Treatment compliance depends on multiple factors. The aim of this study was to evaluate the predicting factors of noncompliance in patients with bipolar I disorder admitted to an Iranian hospital during a six-month follow up period. Materials and Methods This cross-sectional study included 47 bipolar I disorder subjects who were admitted to the Iran psychiatric hospital and that were chosen using a non-randomized convenient sampling model. The patients were assessed at baseline, and at two and six months after admission. For evaluating the patients, we used the medication possession ratio (MPR), the drug attitude inventory (DIA-10), the young mania rating scale (Y-MRS) and the scale for the assessment of positive symptoms (SAPS). The data were analyzed using a general linear model by SPSS 16 software. Results The repeated measures analysis revealed that medication compliance increased successively (P = 0.045), and age, gender and symptom severity did not alter the pattern. Conclusions There is an increasing pattern in treatment compliance in bipolar I disorder patients, regardless of the known predicting factors for nonadherence. PMID:27803718

    Sleep is highly altered during affective episodes in patients with bipolar disorder. There is accumulating evidence that sleep is also altered in euthymic states. A deficit in sleep regulation may be a vulnerability factor with aetiological relevance in the development of the disease. This study aims to explore the objective, subjective and lifetime sleep characteristics of patients with manifest bipolar disorder and persons with an elevated risk of developing the disease. Twenty-two patients with bipolar I and II disorder, nine persons with an elevated risk of developing the disorder and 28 healthy controls were evaluated with a structured interview to characterize subjective and lifetime sleeping habits. In addition, participants wore an actimeter for six nights. Patients with bipolar disorder had longer sleep latency and duration compared with healthy controls as determined by actigraphy. The subjective and lifetime sleep characteristics of bipolar patients differed significantly from healthy controls. The results of participants with an elevated risk of developing the disorder had subjective and lifetime characteristics that were largely analogous to those of patients with manifest bipolar disorder. In particular, both groups described recurring insomnia and hypersomnia, sensitivity to shifts in circadian rhythm, difficulties awakening and prolonged sleep latency. This study provides further evidence that sleep and circadian timing are profoundly altered in patients with bipolar disorder. It may also tentatively suggest that sleep may be altered prior to the first manic episode in subjects at high risk.

    Despite evidence of impairments in social cognition in patients with bipolar disorder (BD), systematic investigations of empathic responding in this population have not been conducted. The objectives of the current study were to investigate empathic responding in patients with BD in varying states of illness and to determine whether course of illness variables and symptom severity predicted responding. Twenty well-characterized patients with BD and 20 matched healthy control subjects completed the Interpersonal Reactivity Index (IRI) and the Social Adjustment Scale Self-Report (SAS-SR), self-report measures of cognitive and emotional empathy and of psychosocial functioning, respectively. Patients with BD reported significantly reduced levels of cognitive empathy ('Perspective Taking') and higher levels of personal distress in response to others' negative experiences than did controls. Altered affective empathic abilities correlated significantly with reduced psychosocial functioning in family, social and occupational domains and with increased symptom severity. This study provides preliminary evidence of alterations in empathic responding in patients with BD. Alterations in the ability to adopt the perspective of others may contribute to the difficulties in social communication inherent in this patient population. Additional studies, involving larger samples, are required to determine the contribution of social cognitive performance to impaired social functioning in BD. PMID:20483472

    Bipolar disorder is a developing disorder; its early stages are sometimes misdiagnosed as anxiety or depressive disorders. At the same time, these disorders are often in comorbidity with bipolar disorder. This complex symptomatology can lead to misinterpretation and underdiagnosis of bipolar disorders, mainly at the earliest stages. Consequently, one of the most important challenges for clinicians is to recognize the non specific early symptoms with the aid of clinical information, for example a family history of bipolar disorder. Furthermore, it is well-known that comorbid anxiety disorders can lead to a worse prognosis in bipolar patients but it is not exactly clear to what extent. A deeper understanding of the relationship between these comorbidities and their stage of development will hopefully lead to better care of patients with bipolar disorder from a younger age.

  12. A limit cycle oscillator model for cycling mood variations of bipolar disorder patients derived from cellular biochemical reaction equations

    We derive a nonlinear limit cycle model for oscillatory mood variations as observed in patients with cycling bipolar disorder. To this end, we consider two signaling pathways leading to the activation of two enzymes that play a key role for cellular and neural processes. We model pathway cross-talk in terms of an inhibitory impact of the first pathway on the second and an excitatory impact of the second on the first. The model also involves a negative feedback loop (inhibitory self-regulation) for the first pathway and a positive feedback loop (excitatory self-regulation) for the second pathway. We demonstrate that due to the cross-talk the biochemical dynamics is described by an oscillator equation. Under disease-free conditions the oscillatory system exhibits a stable fixed point. The breakdown of the self-inhibition of the first pathway at higher concentration levels is studied by means of a scalar control parameter ξ, where ξ equal to zero refers to intact self-inhibition at all concentration levels. Under certain conditions, stable limit cycle solutions emerge at critical parameter values of ξ larger than zero. These oscillations mimic pathological cycling mood variations that emerge due to a disease-induced bifurcation. Consequently, our modeling analysis supports the notion of bipolar disorder as a dynamical disease. In addition, our study establishes a connection between mechanistic biochemical modeling of bipolar disorder and phenomenological nonlinear oscillator approaches to bipolar disorder suggested in the literature.

    Converging evidence suggests bioenergetic abnormalities in bipolar disorder (BD). In the brain, phosphocreatine (PCr) acts a reservoir of high-energy phosphate (HEP) bonds, and creatine kinases (CK) catalyze the transfer of HEP from adenosine triphosphate (ATP) to PCr and from PCr back to ATP, at times of increased need. This study examined the activity of this mechanism in BD by measuring the levels of HEP molecules during a stimulus paradigm that increased local energy demand. Twenty-three patients diagnosed with BD-I and 22 healthy controls (HC) were included. Levels of phosphorus metabolites were measured at baseline and during visual stimulation in the occipital lobe using (31)P magnetic resonance spectroscopy at 4T. Changes in metabolite levels showed different patterns between the groups. During stimulation, HC had significant reductions in PCr but not in ATP, as expected. In contrast, BD patients had significant reductions in ATP but not in PCr. In addition, PCr/ATP ratio was lower at baseline in patients, and there was a higher change in this measure during stimulation. This pattern suggests a disease-related failure to replenish ATP from PCr through CK enzyme catalysis during tissue activation. Further studies measuring the CK flux in BD are required to confirm and extend this finding.

    Life stress is a major predictor of the course of bipolar disorder. Few studies have used laboratory paradigms to examine stress reactivity in bipolar disorder, and none have assessed autonomic reactivity to laboratory stressors. In the present investigation we sought to address this gap in the literature. Participants, 27 diagnosed with bipolar I disorder and 24 controls with no history of mood disorder, were asked to complete a complex working memory task presented as "a test of general intelligence." Self-reported emotions were assessed at baseline and after participants were given task instructions; autonomic physiology was assessed at baseline and continuously during the stressor task. Compared to controls, individuals with bipolar disorder reported greater increases in pretask anxiety from baseline and showed greater cardiovascular threat reactivity during the task. Group differences in cardiovascular threat reactivity were significantly correlated with comorbid anxiety in the bipolar group. Our results suggest that a multimethod approach to assessing stress reactivity-including the use of physiological parameters that differentiate between maladaptive and adaptive profiles of stress responding-can yield valuable information regarding stress sensitivity and its associations with negative affectivity in bipolar disorder.

    This study was aimed to highlight the factors which influence experienced burden, coping and needs for support of caregivers for patients with a bipolar disorder. Research articles meeting content and methodological quality criteria from January 1995 through October 2005 were reviewed. High objective and subjective burden is experienced by these caregivers. Subjective burden is extremely influenced by illness beliefs. High burden is associated more with severity of symptoms (than diagnosis), difficulties in the relationship with patient, lack of support and stigma. Coping is influenced by appraisal and burden. Different phases in the process of caregiving require different coping mechanisms. Little research is available on effectiveness of coping mechanisms and needs for support. Suggestions are nevertheless found in the literature for professional support. Caregivers of patients with a bipolar disorder experience high burden and try to cope in different ways. Little research is available on coping styles and needs for support. However, recommendations can be made to increase support for these caregivers.

    In the present work, metallomics studies using biomolecular (matrix-assisted laser desorption ionization time-of-flight tandem mass spectrometry, MALDI-TOF MS/MS) and elemental mass spectrometry (laser ablation inductively coupled plasma mass spectrometry, LA-ICPMS) of human blood serum samples from bipolar disorder (BD) patients compared to controls were performed. The serum samples from three different groups: control (n = 25), BD patients treated with Li (n = 15), and BD patients not treated with Li (n = 10), were pooled according to their groups and separated by two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). Then, in order to determine the metals bound to the protein spots and search for differences among the studied groups, the 2-D gels were analyzed by LA-ICPMS in three distinct modes: bioimaging of metals in gel sections, line scan through the protein spots, and microlocal analysis of selected protein spots. MALDI-TOF MS/MS characterized 32 serum proteins, and they were associated with the metals previously detected. When comparing control and treated BD patient groups, a differentiation in terms of metals bound to proteins was possible to observe. The main metals bound to proteins found in all groups were Na, Mg, Zn, Ca, and Fe. Mn was only detected in the control group; Co was only observed in the control and BD patients treated with Li group. K and Ti were only found in the BD patient groups, and P was only observed in control and BD patients not treated with Li drugs. This exploratory work shows that the association of LA-ICPMS with MALDI-TOF MS/MS is a powerful strategy in metallomics studies applied to determine differences in metal-containing proteins, being able to play an important role on the discovery of potential markers for BD and its treatment with Li in serum samples.

    Objective The risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders. Method An expert task force iteratively developed consensus through serial consensus-based revisions using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new or reworded items and items that needed to be rerated. This process resulted in the final ISBD Task Force clinical recommendations on antidepressant use in bipolar disorder. Results There is striking incongruity between the wide use of and the weak evidence base for the efficacy and safety of antidepressant drugs in bipolar disorder. Few well-designed, long-term trials of prophylactic benefits have been conducted, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. A major concern is the risk for mood switch to hypomania, mania, and mixed states. Integrating the evidence and the experience of the task force members, a consensus was reached on 12 statements on the use of antidepressants in bipolar disorder. Conclusions Because of limited data, the task force could not make broad statements endorsing antidepressant use but acknowledged that individual bipolar patients may benefit from antidepressants. Regarding safety, serotonin reuptake inhibitors and bupropion may have lower rates of manic switch than tricyclic and tetracyclic antidepressants and norepinephrine-serotonin reuptake inhibitors. The frequency and severity of antidepressant-associated mood elevations appear to be greater in bipolar I than bipolar II disorder. Hence, in bipolar I patients antidepressants should be prescribed only as an adjunct to mood-stabilizing medications

    Exosomes are cellular secretory vesicles containing microRNAs (miRNAs). Once secreted, exosomes are able to attach to recipient cells and release miRNAs potentially modulating the function of the recipient cell. We hypothesized that exosomal miRNA expression in brains of patients diagnosed with schizophrenia (SZ) and bipolar disorder (BD) might differ from controls, reflecting either disease-specific or common aberrations in SZ and BD patients. The sources of the analyzed samples included McLean 66 Cohort Collection (Harvard Brain Tissue Resource Center), BrainNet Europe II (BNE, a consortium of 18 brain banks across Europe) and Boston Medical Center (BMC). Exosomal miRNAs from frozen postmortem prefrontal cortices with well-preserved RNA were isolated and submitted to profiling by Luminex FLEXMAP 3D microfluidic device. Multiple statistical analyses of microarray data suggested that certain exosomal miRNAs were differentially expressed in SZ and BD subjects in comparison to controls. RT-PCR validation confirmed that two miRNAs, miR-497 in SZ samples and miR-29c in BD samples, have significantly increased expression when compared to control samples. These results warrant future studies to evaluate the potential of exosome-derived miRNAs to serve as biomarkers of SZ and BD.

    We present a case of drug-induced myocarditis manifesting as acute heart failure in a young patient with bipolar disorder being treated for depression. The case describes a 20-year-old man being treated in the psychiatry ward for worsening depression when he started complaining of chest pain and shortness of breath. His list of medications included clozapine, lithium, lorazepam, and haloperidol. The main findings on physical examination were tachycardia, low-grade fever, crackles in both lung bases on auscultation, and the absence of any notable edema. Abnormal labs included a troponin of 0.9, with a CK of 245 and CK-MB of 3.1. An ECG revealed sinus tachycardia and left anterior fascicular block (LAFB). An echocardiogram revealed global hypokinesis, severe left ventricular dysfunction with an ejection fraction estimated at 20%. The patient had an admitting diagnosis of acute left ventricular systolic dysfunction likely secondary to drug-induced myocarditis (suspect clozapine) versus acute coronary syndrome. He was managed conservatively and transferred to another facility for endomyocardial biopsy confirming myocarditis. This case is an example of one of the most typical presentations of suspected drug-induced acute myocarditis and will hopefully prompt the reader to think of this underdiagnosed entity in the right clinical setting.

    Background Bipolar disorder (BD) is a chronic mental illness associated with reduced quality of life, high rates of suicide, and high financial costs. Evidence indicates that psychosocial stress might play an important role in the onset and course of BD. Objective The objective of this study was to address the gap between coping theory and the clinical use of coping strategies used to self-manage BD. Methods In-depth interviews were conducted with a sample of 21 poorly adherent patients with BD. All interviews were audiotaped, transcribed verbatim, and analyzed using content analysis with an emphasis on dominant themes. Results Transcript-based analysis generated two major domains of coping strategies used to self-manage BD: 1) problem focused (altering eating habits, managing mood-stabilizing medications, keeping psychiatric appointments, seeking knowledge, self-monitoring, and socializing) and 2) emotion focused (distracting activities, denial, isolation, modifying/avoiding, helping others, and seeking social support). Participants used both types of coping strategies to deal with stressful situations brought about by the internal and external demands associated with self-management of BD. Conclusion This qualitative study provided a first step in evaluating coping strategies as a possible mediator in the self-management of BD and has implications for health care providers. Being able to characterize an individual’s coping behaviors can help patients modify or replace more maladaptive coping with better coping strategies in the self-management of this chronic mental illness.

    Objective Despite increasing interest in cognitive dysfunction in bipolar disorder, little is known about its impact on functional outcome relative to affective symptoms. Method A total of 33 bipolar I subjects were evaluated at index hospitalization and prospectively followed up 15 years later. Affective symptoms, cognition, global functioning, work, and social adjustment were assessed at follow-up and analyzed by linear regression. Results Global functional impairment was significantly associated with poor performance on a cognitive measure of processing speed (WAIS Digit Symbol). Digit symbol performance also was the sole significant predictor of social functioning. Neither symptom severity nor course of illness features significantly contributed to global and social functioning. In contrast, verbal learning deficits, recent depression, and lifetime hospitalizations all were independently associated with work disability. Conclusion Processing speed is robustly associated with social and global functioning in bipolar disorder. Poor work functioning is significantly related to subsyndromal depression, course of illness, and verbal learning deficits. Cognitive and mood symptoms warrant consideration as independent determinants of functioning in patients with bipolar disorder many years after an index manic episode. PMID:20637012

    Bipolar disorder is highly heritable. Cognitive dysfunctions often observed in bipolar patients and their unaffected relatives implicate that these impairments may be associated with genetic predisposition to bipolar disorder and thus fulfill the criteria of a valid endophenotype for the disorder. However, the most fundamental criterion, their heritability, has not been directly studied in any bipolar population. This population-based study estimated the heritability of cognitive functions in bipolar disorder. A comprehensive neuropsychological test battery and the Structured Clinical Interview for DSM-IV were administered to a population-based sample of 110 individuals from 52 families with bipolar disorder. Heritability of cognitive functions as assessed with neuropsychological test scores were estimated using the Solar package. Significant additive heritabilities were found in verbal ability, executive functioning, and psychomotor processing speed. Genetic contribution was low to verbal learning functions. High heritability, in executive functioning and psychomotor processing speed suggest that these may be valid endophenotypic traits for genetic studies of bipolar disorder.

  7. Diagnostic features, prevalence, and impact of bipolar disorder.

    Bipolar disorder shares depressive symptoms with unipolar major depressive disorder but is defined by episodes of mania or hypomania. Bipolar disorder in its broadest sense has a community lifetime prevalence of 4% and is a severely impairing illness that impacts several aspects of patients' lives. Race, ethnicity, and gender have no effect on prevalence rates, but women are more likely to experience rapid cycling, mixed states, depressive episodes, and bipolar II disorder than men. Patients with bipolar disorder have high rates of disability and higher rates of mortality than individuals without bipolar disorder. Natural causes such as cardiovascular disease and diabetes, as well as suicide and other "unnatural" causes are key contributors to the high mortality rate. The costs associated with bipolar disorder include not only the direct costs of treatment, but also the much greater indirect costs of decreased productivity, excess unemployment, and excess mortality.

    2008-01-01

    Background and objective Asperger's Syndrome (AS) is a pervasive developmental disorder that is sometimes unrecognized, especially in the adult psychiatric setting. On the other hand, in patients with an AS diagnosis, comorbid psychiatric disorders may be unrecognized in the juvenile setting. The aim of the paper is to show and discuss some troublesome and complex problems of the management of patients with AS and comorbid Bipolar Disorder (BD). Methods The paper describes three patients affected by AS and bipolar spectrum disorders. Results and conclusion Mood stabilizers and 2nd generation antipsychotics were effective in the treatment of these AS patients with comorbid BD, while the use of antidepressants was associated with worsening of the mood disorder. It is of importance to recognize both the psychiatric diagnoses in order to arrange an exhaustive therapeutic program and to define specific and realistic goals of treatment. PMID:19014623

    We set out to study independent predictor(s) for lifetime and recent substance use disorders (SUDs) in patients with rapid-cycling bipolar disorder (RCBD). Extensive Clinical Interview and Mini-International Neuropsychiatric Interview were used to ascertain DSM-IV Axis I diagnoses of RCBD, anxiety disorders, and SUDs. Data from patients enrolling into four similar clinical trials were used. Where appropriate, univariate analyses with t-test or chi-square were applied. Stepwise logistic regression was used to examine the relationship among predictor variables and lifetime and recent SUDs. Univariate analysis showed that patients with co-occurring anxiety disorders (n = 261) had significantly increased rates of lifetime (odds ratio [OR]= 2.1) and recent (OR = 1.9) alcohol dependence as well as lifetime (OR = 3.4) and recent (OR = 2.5) marijuana dependence compared to those without co-occurring anxiety disorder (n = 303). In logistic regression analyses, generalized anxiety disorder (GAD) was associated with increased risk for lifetime SUDs (OR = 2.34), alcohol dependence (OR = 1.73), and marijuana dependence (OR = 3.36) and recent marijuana dependence (OR = 3.28). A history of physical abuse was associated with increased risk for lifetime SUDs (OR = 1.71) and recent marijuana dependence (OR = 3.47). Earlier onset of first mania/hypomania was associated with increased risk for lifetime SUDs (5% per year), and recent marijuana dependence (12% per year) and later treatment with a mood stabilizer were also associated with increased risk for recent SUDs (8% per year). Positive associations between GAD, later treatment with a mood stabilizer, and early childhood trauma and history of SUDs suggest that adequate treatment of comorbid anxiety, early treatment with a mood stabilizer, and prevention of childhood trauma may reduce the risk for the development of SUDs in patients with bipolar disorder.

    Synopsis Bipolar disorder is a severe and chronic disorder, ranked in the top 10 leading causes of disability worldwide. Sleep disturbances are strongly coupled with inter-episode dysfunction and symptom worsening in bipolar disorder. Experimental studies suggest that sleep deprivation can trigger manic relapse. There is evidence that sleep deprivation can have an adverse impact on emotion regulation the following day. The clinical management of the sleep disturbances experienced by bipolar patients, including insomnia, hypersomnia delayed sleep phase and irregular sleep-wake schedule, may include medication approaches, psychological interventions, light therapies and sleep deprivation. Psychological interventions, as described here, are advantageous in that they are low in side effects, may be preferred by patients, are durable and have no abuse potential. PMID:25750600

    Long-term management of bipolar disorder is a crucial component of treatment because the recurrence of the illness negatively affects patients' daily lives and increases their risks for poor health and suicide. An ideal maintenance treatment for bipolar disorder is relatively simple to take, prevents recurrence of both manic and depressive episodes, and is well-tolerated over the long term. Although many different types of medications are used for maintenance therapy of bipolar disorder, none can be considered ideal for a majority of people with bipolar disorder, and each specific form of therapy has different strengths and limitations. Clinicians need to be aware of unique efficacy and side effect factors when choosing long-term therapy and consider treatment components, goals, and individual patient characteristics, which are essential to the successful long-term management of bipolar disorder. Additionally, several forms of psychotherapy specifically tailored to the needs of people with bipolar disorder should be considered as an adjunct to medication.

    The mechanisms underlying bipolar disorder (BD) and the associated medical burden are unclear. Damage generated by oxidation of nucleosides may be implicated in BD pathophysiology; however, evidence from in vivo studies is limited and the extent of state-related alterations is unclear. This prospective study investigated for we believe the first time the damage generated by oxidation of DNA and RNA strictly in patients with type I BD in a manic or mixed state and subsequent episodes and remission compared with healthy control subjects. Urinary excretion of 8-oxo-deoxyguanosine (8-oxodG) and 8-oxo-guanosine (8-oxoGuo), valid markers of whole-body DNA and RNA damage by oxidation, respectively, was measured in 54 patients with BD I and in 35 healthy control subjects using a modified ultraperformance liquid chromatography and mass spectrometry assay. Repeated measurements were evaluated in various affective phases during a 6- to 12-month period and compared with repeated measurements in healthy control subjects. Independent of lifestyle and demographic variables, a 34% (P<0.0001) increase in RNA damage by oxidation across all affective states, including euthymia, was found in patients with BD I compared with healthy control subjects. Increases in DNA and RNA oxidation of 18% (P<0.0001) and 8% (P=0.02), respectively, were found in manic/hypomanic states compared with euthymia, and levels of 8-oxodG decreased 15% (P<0.0001) from a manic or mixed episode to remission. The results indicate a role for DNA and RNA damage by oxidation in BD pathophysiology and a potential for urinary 8-oxodG and 8-oxoGuo to function as biological markers of diagnosis, state and treatment response in BD.

    Using single strand conformational analysis we screened the complete coding sequence of the serotonin 1F (5-HT{sub 1F}) receptor gene for the presence of DNA sequence variation in a sample of 137 unrelated individuals including 45 schizophrenic patients, 46 bipolar patients, as well as 46 healthy controls. We detected only three rare sequence variants which are characterized by single base pair substitutions, namely a silent T{r_arrow}A transversion in the third position of codon 261 (encoding isoleucine), a silent C{r_arrow}T transition in the third position of codon 176 (encoding histidine), and a C{r_arrow}T transition in position -78 upstream from the start codon. The lack of significant mutations in patients suffering from schizophrenia and bipolar affective disorder indicates that the 5-HT{sub 1F} receptor is not commonly involved in the etiology of these diseases. 12 refs., 1 fig., 2 tabs.

Although our family physician played an integral role in supporting my parents throughout the disease, I did not receive the same support and suffered as a consequence. In this essay, I describe my father's manic and major depressive episodes, as well as my emotions that resulted from the experience. Treating mental illness goes beyond just treating the patient but rather encompasses the family as a whole.

    From a neurobiological perspective there is no such thing as bipolar disorder. Rather, it is almost certainly the case that many somewhat similar, but subtly different, pathological conditions produce a disease state that we currently diagnose as bipolarity. This heterogeneity - reflected in the lack of synergy between our current diagnostic schema and our rapidly advancing scientific understanding of the condition - limits attempts to articulate an integrated perspective on bipolar disorder. However, despite these challenges, scientific findings in recent years are beginning to offer a provisional "unified field theory" of the disease. This theory sees bipolar disorder as a suite of related neurodevelopmental conditions with interconnected functional abnormalities that often appear early in life and worsen over time. In addition to accelerated loss of volume in brain areas known to be essential for mood regulation and cognitive function, consistent findings have emerged at a cellular level, providing evidence that bipolar disorder is reliably associated with dysregulation of glial-neuronal interactions. Among these glial elements are microglia - the brain's primary immune elements, which appear to be overactive in the context of bipolarity. Multiple studies now indicate that inflammation is also increased in the periphery of the body in both the depressive and manic phases of the illness, with at least some return to normality in the euthymic state. These findings are consistent with changes in the hypothalamic-pituitary-adrenal axis, which are known to drive inflammatory activation. In summary, the very fact that no single gene, pathway, or brain abnormality is likely to ever account for the condition is itself an extremely important first step in better articulating an integrated perspective on both its ontological status and pathogenesis. Whether this perspective will translate into the discovery of innumerable more homogeneous forms of bipolarity is one of the

    Background: Fatty acids play various physiological roles in the organism; they are crucial for the structure of cell membranes, metabolic processes, transmission of nerve impulses and brain functions. In recent years, particular attention has been paid to the rich sources of omega-3 for the treatment of many diseases, especially mental illnesses. The present study aimed to investigate the effects of omega-3 supplement in the treatment of patients with bipolar I disorder (BID). Methods: In this double-blind clinical trial, 100 patients suffering from BIDs were randomly divided into two, i.e. control (n = 50) and experimental (n = 50) groups. In addition to the other standard treatments, 1000 mg of omega-3 supplement was given to the experimental group on daily basis for 3 months and placebo was given to the control group. The Young Mania Rating Scale was completed for both groups before and after the intervention. Afterward, data were analyzed using paired t-test, independent t-test, and Chi-square test. Results: Before intervention, mean severity of mania in the experimental group (23.50 ± 7.02) and control group (23.70 ± 8.09) was not significant (P ≤ 0.89). The difference after the intervention in the experimental group (10.64 ± 3.3) and control group (20.12 ± 6.78) was significant (P < 0.01). The mean intensity of mania before (23.50 ± 7.02) and after (10.64 ± 3.3) intervention reported to be significant at P < 0.05. Conclusions: Since omega-3 supplement was effective for the treatment of BID, it is suggested to use omega-3 supplements as an adjuvant therapy along with the other pharmacotherapies. PMID:27280013

    Background Propofol is often used as an anesthetic agent for electroconvulsive therapy (ECT). In recent studies, propofol was shown to possess significant seizure-shortening properties during ECT. “Valproate” is a mood stabilizer used mainly in the treatment of bipolar affective disorder. It is reported that valproate, being an anticonvulsant, raises the seizure threshold, thus decreases the efficacy of ECT treatment. Aim The purpose of our study was to compare the dose of propofol in valproate-using patients and valproate-free patients. Methods In an open design, 17 patients with bipolar affective disorder manic episodes who were to be treated with valproate and ECT in combination, were compared with 16 manic-episode patients who were to be treated with ECT but not valproate. The two groups were compared on the basis of electroencephalography-registered seizure duration and the propofol dosage required to induce anesthesia. Results Valproate, compared with no valproate treatment, results in a decrease in the propofol dose required to induce anesthesia. In the valproate group of study participants, seizure duration was significantly shorter than in the valproate-free group. Conclusion The results suggest that valproate reduces the dose of propofol required for anesthesia during ECT treatment in patients with bipolar affective disorder manic episodes. Although propofol is a safe and efficacious anesthetic for ECT treatment, lower doses of propofol should be used to induce anesthesia for patients under valproate treatment. When the clinician needs to prolong seizure duration in patients treated with valproate, interruption of the valproate treatment or an anesthetic agent other than propofol should be considered.

    Objectives Aberrant DNA methylation and gene expression have been reported in postmortem brain tissues of psychotic patients, but until now there has been no systematic evaluation of synergistic changes in methylation and expression on a genome-wide scale from brain tissue. Methods In this study, genome-wide methylation and expression analysis were performed on cerebellum samples from 39 patients with schizophrenia, 36 patients with bipolar disorder, and 43 unaffected controls, to screen for the correlation in gene expression and CpG methylation. Results Out of 71,753 CpG Gene Pairs (CGPs) tested across the genome, 204 were found to significantly correlate with gene expression after correction for multiple testing [p < 0.05, false discovery rate (FDR) q < 0.05]. The correlated CGPs were tested for disease-associated expression and methylation by comparing psychotic patients with bipolar disorder and schizophrenia to healthy controls. Four of the identified CGPs were found to significantly correlate with the differential expression and methylation of the PIK3R1, BTN3A3, NHLH1, and SLC16A7 in psychotic patients (p < 0.05, FDR q < 0.2). Additional expression and methylation datasets were used to validate the relationship between DNA methylation, gene expression, and neuropsychiatric diseases. Conclusions These results suggest that the identified differentially expressed genes with an aberrant methylation pattern can represent novel candidate factors in the etiology and pathology of neuropsychiatric disorders.

    For many disorders, patient heterogeneity requires physicians to customize their treatment to each patient's needs. We test for the existence of customization in physicians' prescribing for bipolar disorder, using data from a naturalistic clinical effectiveness trial of bipolar disorder treatment (STEP-BD), which did not constrain physician prescribing. Multinomial logit is used to model the physician's choice among five combinations of drug classes. We find that our observed measure of the patient's clinical status played only a limited role in the choice among drug class combinations, even for conditions such as mania that are expected to affect class choice. However, treatment of a patient with given characteristics differed widely depending on which physician was seen. The explanatory power of the model was low. There was variation within each physician's prescribing, but the results do not suggest a high degree of customization in physicians' prescribing, based on our measure of clinical status.

    A few weeks after suffering from a basal ganglia infarction (globus pallidus) with left-sided hemiplegia, a 23-year-old woman exhibited for the first time a pronounced mania with self-endangerment. The use of oral contraceptives was the only determinable risk factor. During the further course, the mother also developed a depressive disorder. Thus a certain genetic predisposition for affective disorders may be relevant, although this would not explain the outbreak by itself. An association between the right-sided basal ganglia infarction and the occurrence of a bipolar affective disorder has been described in the literature. Vascular or, respectively, inflammatory risk factors in synopsis with the aetiopathogenesis of bipolar affective disorders are also discussed in depth in this case report. PMID:23939559

    Many studies suggest the presence of aberrations in cellular metabolism in bipolar disorder. We studied the metabolome in bipolar disorder to gain insight into cellular pathways that may be dysregulated in bipolar disorder and to discover evidence of novel biomarkers. We measured polar and nonpolar metabolites in fibroblasts from subjects with bipolar I disorder and matched healthy control subjects, under normal conditions and with two physiologic perturbations: low-glucose media and exposure to the stress-mediating hormone dexamethasone. Metabolites that were significantly different between bipolar and control subjects showed distinct separation by principal components analysis methods. The most statistically significant findings were observed in the perturbation experiments. The metabolite with the lowest p value in both the low-glucose and dexamethasone experiments was α-aminoadipate, whose intracellular level was consistently lower in bipolar subjects. Our study implicates α-aminoadipate as a possible biomarker in bipolar disorder that manifests under cellular stress. This is an intriguing finding given the known role of α-aminoadipate in the modulation of kynurenic acid in the brain, especially as abnormal kynurenic acid levels have been implicated in bipolar disorder.

    Recent studies have suggested that some variants of bipolar disorder (BD) may be due to hyperconnectivity between orbitofrontal (OFC) and temporal pole (TP) structures in the dominant hemisphere. Some initial MRI studies noticed that there were corpus callosum abnormalities within specific regional areas and it was hypothesized that developmentally this could result in functional or effective connectivity changes within the orbitofrontal-basal ganglia-thalamocortical circuits. Recent diffusion tensor imaging (DTI) white matter fiber tractography studies may well be superior to region of interest (ROI) DTI in understanding BD. A “ventral semantic stream” has been discovered connecting the TP and OFC through the uncinate and inferior longitudinal fasciculi and the elusive TP is known to be involved in theory of mind and complex narrative understanding tasks. The OFC is involved in abstract valuation in goal and sub-goal structures and the TP may be critical in binding semantic memory with person–emotion linkages associated with narrative. BD patients have relative attenuation of performance on visuoconstructional praxis consistent with an atypical localization of cognitive functions. Multiple lines of evidence suggest that some BD alleles are being selected for which could explain the enhanced creativity in higher-ability probands. Associations between ROI’s that are not normally connected could explain the higher incidence of artistic aptitude, writing ability, and scientific achievements among some mood disorder subjects.

    The empathic abilities have never been examined in bipolar disorder patients, despite frequent observations of impaired social behavior. To examine the neuropsychological processes that underlie the affective and cognitive empathic ability in bipolar disorder, the authors compared affective and cognitive empathic abilities, as well as theory of mind and executive functions, of euthymic bipolar disorder patients and healthy comparison subjects. Significant deficits in cognitive empathy and theory of mind were observed, while affective empathy was elevated in bipolar disorder. Patients showed impaired cognitive flexibility (shifting and reversal learning) but intact planning behavior. Impaired cognitive empathy was related with performance in neurocognitive tasks of cognitive flexibility, suggesting that prefrontal cortical dysfunction may account for impaired cognitive empathy in bipolar disorder.

    Current pharmacotherapy for bipolar disorder (BPD) is generally unsatisfactory for a large number of patients. Even with adequate modern bipolar pharmacological therapies, many afflicted individuals continue to have persistent mood episode relapses, residual symptoms, functional impairment and psychosocial disability. Creating novel therapeutics for BPD is urgently needed. Promising drug targets and compounds for BPD worthy of further study involve the following systems: purinergic, dynorphin opioid neuropeptide, cholinergic (muscarinic and nicotinic), melatonin and serotonin (5-HT2C receptor), glutamatergic, hypothalamic-pituitary adrenal (HPA) axis have all been implicated. Intracellular pathways and targets worthy of further study include glycogen synthase kinase-3 protein, protein kinase C, arachidonic acid cascade. PMID:18704977

  12. Targeting astrocytes in bipolar disorder.

    Astrocytes are homeostatic cells of the central nervous system, which are critical for development and maintenance of synaptic transmission and hence of synaptically connected neuronal ensembles. Astrocytic densities are reduced in bipolar disorder, and therefore deficient astroglial function may contribute to overall disbalance in neurotransmission and to pathological evolution. Classical anti-bipolar drugs (lithium salts, valproic acid and carbamazepine) affect expression of astroglial genes and modify astroglial signalling and homeostatic cascades. Many effects of both antidepressant and anti-bipolar drugs are exerted through regulation of glutamate homeostasis and glutamatergic transmission, through K(+) buffering, through regulation of calcium-dependent phospholipase A2 (that controls metabolism of arachidonic acid) or through Ca(2+) homeostatic and signalling pathways. Sometimes anti-depressant and anti-bipolar drugs exert opposite effects, and some effects on gene expression in drug treated animals are opposite in neurones vs. astrocytes. Changes in the intracellular pH induced by anti-bipolar drugs affect uptake of myo-inositol and thereby signalling via inositoltrisphosphate (InsP3), this being in accord with one of the main theories of mechanism of action for these drugs.

    There is accumulating evidence for an increased prevalence of metabolic syndrome (MetS) in bipolar patients, which is comparable to the prevalence of MetS in patients with schizophrenia. Hyperhomocysteinaemia has emerged as an independent and graded risk factor for the development of cardiovascular disease (CVD), which is, at the same time, the primary clinical outcome of MetS. The aim of this study was to ascertain if the presence of MetS was associated with hyperhomocysteinaemia in patients with bipolar disorder (N=36) and schizophrenia (N=46) treated with second-generation antipsychotics (SGA). MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP-III) criteria and the cut-off point for hyperhomocysteinaemia was set up at 15 μmoll(-1). Results of the study indicated that the presence of the MetS is statistically significantly associated with the elevated serum homocysteine in all participants. As hyperhomocysteinaemia has emerged as an independent risk factor for psychiatric disorder and CVD, it could be useful to include fasting homocysteine serum determination in the diagnostic panels of psychiatric patients to obtain a better assessment of their metabolic risk profile.

    This study aimed to assess stigma and its sociodemographic and clinical correlates among patients with bipolar disorder while in remission. 185 patients currently in remission were assessed on Internalized Stigma of Mental Illness Scale (ISMIS) for internalized stigma, Explanatory Model Interview Catalogue Stigma Scale for perceived stigma and Participation scale for restriction of activities. About 28% patients reported moderate to high level of self stigma as assessed by ISMIS total score. Discrimination experience (38.9%) was reported to be the most commonly experienced self stigma followed by alienation (28.6%) and social withdrawal (28.6%). On the participation scale, about two-fifth (42%) of the participants had severe restriction of activities. Internalized stigma was higher among those with lower age and lesser income. Higher level of stigma was associated with shorter mean duration of remission, income, mean duration of depressive episodes, higher severity of residual depressive symptoms and current level of functioning. Higher internalized stigma was associated with greater restriction in participation of activities. To conclude, present study suggests that self stigma is highly prevalent among patients with bipolar disorder in India and is associated with clinical variables like duration of depressive episodes and level of functioning.

    From a neurobiological perspective there is no such thing as bipolar disorder. Rather, it is almost certainly the case that many somewhat similar, but subtly different, pathological conditions produce a disease state that we currently diagnose as bipolarity. This heterogeneity – reflected in the lack of synergy between our current diagnostic schema and our rapidly advancing scientific understanding of the condition – limits attempts to articulate an integrated perspective on bipolar disorder. However, despite these challenges, scientific findings in recent years are beginning to offer a provisional “unified field theory” of the disease. This theory sees bipolar disorder as a suite of related neurodevelopmental conditions with interconnected functional abnormalities that often appear early in life and worsen over time. In addition to accelerated loss of volume in brain areas known to be essential for mood regulation and cognitive function, consistent findings have emerged at a cellular level, providing evidence that bipolar disorder is reliably associated with dysregulation of glial–neuronal interactions. Among these glial elements are microglia – the brain’s primary immune elements, which appear to be overactive in the context of bipolarity. Multiple studies now indicate that inflammation is also increased in the periphery of the body in both the depressive and manic phases of the illness, with at least some return to normality in the euthymic state. These findings are consistent with changes in the hypothalamic–pituitary–adrenal axis, which are known to drive inflammatory activation. In summary, the very fact that no single gene, pathway, or brain abnormality is likely to ever account for the condition is itself an extremely important first step in better articulating an integrated perspective on both its ontological status and pathogenesis. Whether this perspective will translate into the discovery of innumerable more homogeneous forms of

    The growing literature shows the pervasiveness and importance of comorbidity in youth with bipolar disorder (BPD). For instance, up to 90% of youth with BPD have been described to manifest comorbidity with attention-deficit hyperactivity disorder. Multiple anxiety, substance use, and disruptive behavior disorders are the other most commonly reported comorbidities with BPD. Moreover, important recent data highlight the importance of obsessive-compulsive and pervasive developmental illness in the context of BPD. Data suggest that not only special developmental relationships are operant in the context of comorbidity but also that the presence of comorbid disorders with BPD results in a more severe clinical condition. Moreover, the presence of comorbidity has therapeutic implications for the treatment response for both BPD and the associated comorbid disorder. Future longitudinal studies to address the relationship and the impact of comorbid disorders on course and therapeutic response over time are required in youth with BPD. PMID:19264265

    We review preclinical and clinical evidences strongly suggesting that memantine, an old drug currently approved for Alzheimer’s dementia, is an effective treatment for acute mania and for the prevention of manic/hypomanic and depressive recurrences of manic-depressive illness. Lithium remains the first line for the treatment and prophylaxis of bipolar disorders, but currently available treatment alternatives for lithium resistant patients are of limited and/or questionable efficacy. Thus, research and development of more effective mood stabilizer drugs is a leading challenge for modern psychopharmacology. We have demonstrated that 21 d administration of imipramine causes a behavioural syndrome similar to a cycle of bipolar disorder, i.e., a mania followed by a depression, in rats. Indeed, such treatment causes a behavioural supersensitivity to dopamine D2 receptor agonists associated with an increase sexual activity and aggressivity (mania). The dopamine receptor sensitization is followed, after imipramine discontinuation, by an opposite phenomenon (dopamine receptor desensitization) and an increased immobility time (depression) in the forced swimming test of depression. Memantine blocks the development of the supersensitivity and the ensuing desensitization associated with the depressive like behavior. On the basis of these observations we have suggested the use of memantine in the treatment of mania and in the prophylaxis of bipolar disorders. To test this hypothesis we performed several naturalistic studies that showed an acute antimanic effect and a long-lasting and progressive mood-stabilizing action (at least 3 years), without clinically relevant side effects. To confirm the observations of our naturalistic trials we are now performing a randomized controlled clinical trial. Finally we described the studies reporting the efficacy of memantine in manic-like symptoms occurring in psychiatric disorders other than bipolar. Limitations: A randomized controlled

    Approximately 40% of patients with bipolar disorder experience mixed episodes, defined as a manic state with depressive features, or manic symptoms in a patient with bipolar depression. Compared with bipolar patients without mixed features, patients with bipolar mixed states generally have more severe symptomatology, more lifetime episodes of illness, worse clinical outcomes and higher rates of comorbidities, and thus present a significant clinical challenge. Most clinical trials have investigated second-generation neuroleptic monotherapy, monotherapy with anticonvulsants or lithium, combination therapy, and electroconvulsive therapy (ECT). Neuroleptic drugs are often used alone or in combination with anticonvulsants or lithium for preventive treatment, and ECT is an effective treatment for mixed manic episodes in situations where medication fails or cannot be used. Common antidepressants have been shown to worsen mania symptoms during mixed episodes without necessarily improving depressive symptoms; thus, they are not recommended during mixed episodes. A greater understanding of pathophysiological processes in bipolar disorder is now required to provide a more accurate diagnosis and new personalised treatment approaches. Targeted, specific treatments developed through a greater understanding of bipolar disorder pathophysiology, capable of affecting the underlying disease processes, could well prove to be more effective, faster acting, and better tolerated than existing therapies, therefore providing better outcomes for individuals affected by bipolar disorder. Until such time as targeted agents are available, second-generation neuroleptics are emerging as the treatment of choice in the management of mixed states in bipolar disorder.

    Background The aim of this observational study was to determine whether subthreshold bipolarity affects treatment response and remission in patients with major depressive disorder receiving antidepressant (AD) monotherapy over a 6-month follow-up period. Methods Seventy-eight patients with major depressive disorder were stratified into two subgroups according to the presence of subthreshold bipolarity, identified using the Korean version of the Mood Disorder Questionnaire (K-MDQ), which classifies patients as positive for a screening of bipolarity based on the cutoff for the total K-MDQ score (ie, 7 points). They received AD monotherapy such as escitalopram, sertraline, paroxetine, or tianeptine for 6 months. The Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Scale, and Beck Scale for Suicide Ideation were applied at baseline, 1 week, 3 weeks, 2 months, 3 months, and 6 months. Results The mean HAMD, BDI, and Beck Scale for Suicide Ideation scores were higher in the bipolarity group than in the nonbipolarity group at 3 weeks. The mean BDI score was also higher in the bipolarity group than in the nonbipolarity group at 6 months. Evaluation of the ratio of improvement for each scale revealed different patterns of percentage changes between the two groups over the 6-month follow-up period. Furthermore, the response and remission rates (as assessed using BDI and HAMD scores) were higher in the nonbipolarity group than in the bipolarity group, with the exception of HAMD scores at the 3-week follow-up time point. Conclusion The findings of this study showed that depressed patients with bipolarity had a worse response to AD monotherapy than did those without bipolarity. PMID:27274258

    Bipolar Disorder is a severe disease characterized by pathological mood swings from major depressive episodes to manic ones and vice versa. The biological underpinnings of Bipolar Disorder have yet to be defined. As a consequence, pharmacological treatments are suboptimal. In the present paper we test the hypothesis that the molecular pathways involved with the direct targets of lithium, hold significantly more genetic variations associated with BD. A molecular pathway approach finds its rationale in the polygenic nature of the disease. The pathways were tested in a sample of ∼ 7,000 patients and controls. Data are available from the public NIMH database. The definition of the pathways was conducted according to the National Cancer Institute (http://pid.nci.nih.gov/). As a result, 3 out of the 18 tested pathways related to lithium action resisted the permutation analysis and were found to be associated with BD. These pathways were related to Reelin, Integrins and Aurora. A pool of genes selected from the ones linked with the above pathways was further investigated in order to identify the fine molecular mechanics shared by our significant pathways and also their link with lithium mechanism of action. The data obtained point out to a possible involvement of microtubule-related mechanics. PMID:26551401

    Previous antemortem and postmortem tissue fatty acid composition studies have observed significant deficits in the omega-3 fatty acid docosahexaenoic acid (DHA, 22:6n-3) in red blood cell (RBC) and postmortem cortical membranes of patients with unipolar depression. In the present we determined the fatty acid composition of postmortem orbitofrontal cortex (OFC, Brodmann area 10) of patients with bipolar disorder (n=18) and age-matched normal controls (n=19) by gas chromatography. After correction for multiple comparisons, DHA (-24%), arachidonic acid (-14%), and stearic acid (C18:0)(-4.5%) compositions were significantly lower, and cis-vaccenic acid (18:1n-7)(+12.5%) composition significantly higher, in the OFC of bipolar patients relative to normal controls. Based on metabolite:precursor ratios, significant elevations in arachidonic acid, stearic acid, and palmitic acid conversion/metabolism were observed in the OFC of bipolar patients, and were inversely correlated with DHA composition. Deficits in OFC DHA and arachidonic acid composition, and elevations in arachidonic acid metabolism, were numerically (but not significantly) greater in drug-free bipolar patients relative to patients treated with mood-stabilizer or antipsychotic medications. OFC DHA and arachidonic acid deficits were greater in patients plus normal controls with high versus low alcohol abuse severity. These results add to a growing body of evidence implicating omega-3 fatty acid deficiency as well as the OFC in the pathoaetiology of bipolar disorder. PMID:18715653

    The aim of this research was to test the long-term efficacy of combined standard treatment (pharmacotherapy and adjunctive psychosocial treatment based on a cognitive-behavioral model) compared with standard drug treatment for patients with recurrent bipolar disorder. Twenty patients selected according to DSM-IV-TR criteria were randomized to 1) combined treatment or 2) control treatment. A multigroup experimental design with repeated assessment measures (pre-treatment, post-treatment, 6-month follow-up, and 12-month follow-up) was used. Results of the repeated measurement analysis showed a significant increment in scores of Global Activity Functioning within the combined treatment group during the follow-up, which was not observed in the control treatment group. Therefore, the effectiveness of psychotherapy tends to increase with time, and this improvement is not significant until 12 months of follow-up.

    Genetic studies in medicine exploited age of onset as a criterion to delineate subgroups of illness. Bipolar patients stratified with this criterion were shown to share clinical characteristics and patterns of inheritance of illness. The molecular mechanisms driving the biological clock in the suprachiasmatic nucleus of the hypothalamus may play a role in mood disorders. A single nucleotide polymorphism (SNP) (-50 T/C) falling into the effective promoter region (nt -171 to +29) of the gene coding for glycogen synthase kinase 3-beta (GSK3-beta) has been identified. GSK3-beta codes for an enzyme which is a target for the action of lithium and which is also known to regulate circadian rhythms in Drosophila. We studied the effect of this polymorphism on the age at onset of bipolar disorder type I. A homogeneous sample of 185 Italian patients affected by bipolar disorder was genotyped. Age at onset was retrospectively ascertained with best estimation procedures. No association was detected between GSK3-beta -50 T/C SNP and the presence of bipolar illness. Homozygotes for the wild variant (T/T) showed an earlier age at onset than carriers of the mutant allele (F=5.53, d.f.=2,182, P=0.0047). Results warrant interest for the variants of genes pertaining to the molecular clock as possible endophenotypes of bipolar disorder, but caution ought to be taken in interpreting these preliminary results and future replication studies must be awaited.

    In recent years much attention has been given to determine risk factors for suicide among adults with bipolar disorder. Such studies concerning children and youths, which would also take into account the specificity of the developmental age, are still too few. The ability to identify risk factors for children and youths with mood disorders, as well as the possibility to monitor them, is an essential element in preventing suicidal behaviours. Previous studies have clearly indicated that in the group of patients with an early onset of the bipolar disorder the occurrence of suicidal thoughts and intentions were significantly increased. Identifying the risk of suicide is hindered further by the complexity of the phenomenon, which is a compound interaction of various factors: biological, environmental, sociological, psychological and clinical. This is especially true with young adults suffering from mental illness and presenting a number of other psychopathological symptoms. The following paper introduces and reviews the results of current studies, which analysed the risk factors for suicide among children and youths with bipolar spectrum or already diagnosed with bipolar disorder. For this purpose we conducted the overview of recent years literature available in PubMed/MEDLINE database, including the following search criteria: early onset bipolar disorder, bipolar disorder in children and young people, the spectrum of bipolar disorder, and suicidal ideation, suicidal intent, suicide.

    2014-01-01

    Objective: To determine if any monotherapy drug treatment has robust efficacy to treat comorbid bipolar disorder and chronic pain. Data Sources: The American Psychiatric Association (APA) treatment guidelines for bipolar mood disorder and the 2012 Cochrane database for pain disorders. Study Selection: We relied on the treatment guides to determine if the drugs that are APA guideline–supported to treat bipolar disorder have supporting data from the Cochrane database for chronic pain. Data Synthesis: No single drug was mentioned by either guideline to treat this comorbidity. However, carbamazepine was the only drug that has guideline-supported robust efficacy in the management of each condition separately. Conclusions: Carbamazepine was found to have strong preclinical data for the treatment of comorbid bipolar mood disorder and chronic pain disorders. While requiring more studies in this population, we propose that this treatment modality may benefit patients. PMID:25667814

    Bipolar disorder and unipolar depressive disorder (UD) may be different in brain structure. In the present study, we performed voxel-based morphometry (VBM) to quantify the grey matter volumes in 23 patients with bipolar I depressive disorder (BP1) and 23 patients with UD, and 23 age-, gender-, and education-matched healthy controls (HCs) using magnetic resonance imaging. We found that compared with the HC and UD groups, the BP1 group showed reduced grey matter volumes in the right inferior frontal gyrus and middle cingulate gyrus, while the UD group showed reduced volume in the right inferior frontal gyrus compared to HCs. In addition, correlation analyses revealed that the grey matter volumes of these regions were negatively correlated with the Hamilton depression rating scores. Taken together, the results of our study suggest that decreased grey matter volume of the right inferior frontal gyrus is a common abnormality in BP1 and UD, and decreased grey matter volume in the right middle cingulate gyrus may be specific to BP1.

    Introduction It has recently been highlighted that patients affected by schizophrenia (SCZ) and those affected by bipolar disorder (BD) undergo gradual chronic worsening of cognitive and social functioning. The objective of the current study was to evaluate and compare (using the Facial Action Coding System [FACS]) the way by which patients with the two disorders experience and display emotions in relation to specific emotional stimuli. Materials and methods Forty-five individuals participated in the study: 15 SCZ patients, 15 BD patients, and 15 healthy controls. All participants watched emotion-eliciting video clips while their facial activity was videotaped. The congruent/incongruent feeling of emotions and the facial expression in reaction to emotions were evaluated. Results SCZ and BD patients presented similar incongruent emotive feelings and facial expressions (significantly worse than healthy participants); SCZ patients expressed the emotion of disgust significantly less appropriately than BD patients. Discussion BD and SCZ patients seem to present a similar relevant impairment in both experiencing and displaying emotions; this impairment may be seen as a behavioral indicator of the deficit of social cognition present in both the disorders. As the disgust emotion is mainly elaborated in the insular cortex, the incongruent expression of disgust of SCZ patients can be interpreted as a further evidence of a functional deficit of the insular cortex in this disease. Specific remediation training could be used to improve emotion and social cognition in SCZ and BD patients. PMID:23966784

    General practitioners are involved in the continuing care and shared care of patients with chronic mental illness, including bipolar disorder. Psychiatrists are particularly reliant on GPs to monitor and treat comorbidities as well as the psychiatric condition itself. Management of chronic mental illness is compromised by a number of factors, including problems with diagnosis, physical comorbidity, erratic attendance and poor compliance with treatment. Diagnosis of bipolar disorder is often delayed, and differential diagnoses to be considered include unipolar depression, anxiety disorder, drug and alcohol dependence, personality disorder, attention deficit hyperactivity disorder, and general medical and central nervous system diseases. New Medicare items have been introduced under the Better Access to Mental Health Care initiative. However, uptake for patients with chronic psychiatric illness, including bipolar disorder, is low. Patients with bipolar disorder may be prone to a range of comorbid psychological, social and physical problems, and GPs need to be vigilant to detect and manage comorbidity and social problems as part of the overall plan. This includes assistance with certification for sickness and unemployment benefits. GPs may become involved during crises affecting patients and this may pose significant problems for GPs who need to provide ongoing care following patient discharge from hospital. Despite these difficulties, opportunities exist for GPs to play a vital and ongoing role in the management of patients with bipolar disorder. PMID:20712554

    The hypothesis that viruses or other infectious agents may cause schizophrenia or bipolar disorder dates to the 19th century but has recently been revived. It could explain many clinical, genetic, and epidemiologic aspects of these diseases, including the winter-spring birth seasonality, regional differences, urban birth, household crowding, having an older sibling, and prenatal exposure to influenza as risk factors. It could also explain observed immunological changes such as abnormalities of lymphocytes, proteins, autoantibodies, and cytokines. However, direct studies of viral infections in individuals with these psychiatric diseases have been predominantly negative. Most studies have examined antibodies in blood or cerebrospinal fluid, and relatively few studies have been done on viral antigens, genomes, cytopathic effect on cell culture, and animal transmission experiments. Viral research on schizophrenia and bipolar disorder is thus comparable to viral research on multiple sclerosis and Parkinson's disease: an attractive hypothesis with scattered interesting findings but no clear proof. The application of molecular biological techniques may allow the identification of novel infectious agents and the associations of these novel agents with serious mental diseases. PMID:7704891

    Complex diseases may be associated with combinations of changes in DNA, where the single change has little impact alone. In a previous study of patients with bipolar disorder and controls combinations of SNP genotypes were analyzed, and four large clusters of combinations were found to be significantly associated with bipolar disorder. It has now been found that these clusters may be connected to clinical data. PMID:23028568

    Impulsive risk taking contributes to deleterious outcomes among clinical populations. Indeed, pathological impulsivity and risk taking are common in patients with serious mental illness, and have severe clinical repercussions including novelty seeking, response disinhibition, aggression, and substance abuse. Thus, the current study seeks to examine self-reported impulsivity (Barratt Impulsivity Scale) and performance-based behavioral risk taking (Balloon Analogue Risk Task) in bipolar disorder and schizophrenia. Participants included 68 individuals with bipolar disorder, 38 with schizophrenia, and 36 healthy controls. Self-reported impulsivity was elevated in the bipolar group compared with schizophrenia patients and healthy controls, who did not differ from each other. On the risk-taking task, schizophrenia patients were significantly more risk averse than the bipolar patients and controls. Aside from the diagnostic group differences, there was a significant effect of antipsychotic (AP) medication within the bipolar group: bipolar patients taking AP medications were more risk averse than those not taking AP medications. This difference in risk taking because of AP medications was not explained by history of psychosis. Similarly, the differences in risk taking between schizophrenia and bipolar disorder were not fully explained by AP effects. Implications for clinical practice and future research are discussed.

    Objective: Emerging evidence suggests that inflammation and neurodegeneration underlies bipolar disorder. To investigate biological markers of cytokines and brain-derived neurotrophic factor between bipolar I, bipolar II, and other specified bipolar disorder with short duration hypomania may support the association with inflammatory dysregulation and bipolar disorder and, more specifically, provide evidence for other specified bipolar disorder with short duration hypomania patients were similar to bipolar II disorder patients from a biological marker perspective. Methods: We enrolled patients with bipolar I disorder (n=234), bipolar II disorder (n=260), other specified bipolar disorder with short duration hypomania (n=243), and healthy controls (n=140). Their clinical symptoms were rated using the Hamilton Depression Rating Scale and Young Mania Rating Scale. Inflammatory cytokine (tumor necrosis factor-α, C-reactive protein, transforming growth factor-β1, and interleukin-8) and brain-derived neurotrophic factor levels were measured in each group. Multivariate analysis of covariance and linear regression controlled for possible confounders were used to compare cytokine and brain-derived neurotrophic factor levels among the groups. Results: Multivariate analysis of covariance adjusted for age and sex and a main effect of diagnosis was significant (P<.001). Three of the 5 measured biomarkers (tumor necrosis factor-α, transforming growth factor-β1, and interleukin-8) were significantly (P=.006, .01, and <.001) higher in all bipolar disorder patients than in controls. Moreover, covarying for multiple associated confounders showed that bipolar I disorder patients had significantly higher IL-8 levels than did bipolar II disorder and other specified bipolar disorder with short duration hypomania patients in multivariate analysis of covariance (P=.03) and linear regression (P=.02) analyses.

    Abstract Patients with bipolar II disorder (BDII) have a higher prevalence rate of metabolic disturbance. Whether BDII itself, in addition to its current standard treatment, is a risk factor for metabolic syndrome warrants additional study. The dopamine receptor D3 (DRD3) gene, one of the candidate genes for BDII, is also involved in the dopaminergic system. We investigated whether it is related to changes in the metabolic indices of patients with BDII given 12 weeks of standard treatment. Patients with a first diagnosis of BDII (n = 117) were recruited. Metabolic profiles (cholesterol, triglycerides, fasting serum glucose, body mass index) were measured at baseline and at 2, 8, and 12 weeks. The genotype of the DRD3 Ser9Gly polymorphism (rs6280) was determined. Multiple linear regressions with generalized estimating equation methods were used. Seventy-six (65.0%) patients completed the 12-week intervention. Significant differences in triglyceride change were associated with the DRD3 Ser9Gly genotype (P = 0.03). Patients with the Ser/Ser genotype had significantly smaller triglyceride increases and a lower risk of developing metabolic syndrome than did those with the Ser/Gly+Gly/Gly genotype. However, the associations between the DRD3 Ser9Gly polymorphism with changes in triglyceride level become nonsignificant after correcting for multiple comparisons. We conclude that the DRD3 Ser9Gly polymorphism is nominally associated with changes in triglycerides and metabolic syndrome after 12 weeks of standard BDII treatment. PMID:27310943

    Tourette syndrome consists of multiple motor tics and one or more vocal tics. Psychopathology occurs in approximately 90% of Tourette syndrome patients, with attention-deficit/hyperactivity, mood, and obsessive-compulsive disorders being common. Additionally, Tourette syndrome and bipolar disorder may be related in some individuals. However, it is unclear why bipolar disorder may be overrepresented in Tourette syndrome patients, and more research is needed. Herein, we report the case of a 15-year-old boy diagnosed with both Tourette syndrome and bipolar disorder, whose symptoms improved with aripiprazole, atomoxetine, and valproate. The patient was diagnosed with Tourette syndrome at 8 years of age when he developed tics and experienced his first depressive episode. The patient had a poor response to a variety of antidepressants and anti-tic medications. A combination of valproate and aripiprazole stabilized both the patient's tics and mood symptoms. It is important to assess individuals with Tourette syndrome for other disorders, including bipolar disorder. The treatment of children and adolescents with both Tourette syndrome and bipolar disorder is an important clinical issue. PMID:25598829

    Bipolar disorder is a chronic and often devastating illness that may go undiagnosed because of its complex and diverse presentation. Clinicians can provide psychological treatments, in conjunction with pharmacotherapy, that can reduce the frequency, severity, and duration of manic and depressive episodes. Because bipolar disorder is characterized by high degrees of comorbidity and high rates of medical complications, the clinician will frequently need to implement other treatments targeted to comorbid conditions, such as panic, generalized anxiety, substance abuse, and personality disorders. This article introduces the issue of Journal of Clinical Psychology: In Session devoted to the treatment of bipolar disorder. We describe the cognitive styles and personal vulnerabilities that pose greater risk for bipolar disorder. Three evidence-based psychological treatments (interpersonal social rhythm therapy, family-focused treatment, and cognitive-behavioral therapy) and current pharmacological treatments are examined and illustrated. Finally, we review the effectiveness and practice implications of a variety of treatments for this severe and underresearched disorder.

    Compared rehospitalization rates in patients with schizophrenia or bipolar I disorder to patients with major depressive disorder remains unclear. This study aimed to compare the time to rehospitalization of the three groups. Other clinical variables were also examined. Rehospitalization status was monitored for all admitted inpatients with schizophrenia (n=637), bipolar I disorder (n=197), or major depressive disorder (n=191), from January 1, 2006 to December 31, 2006. Time to rehospitalization within 1 year after discharge was measured using the Kaplan-Meier method. Risk factors associated with rehospitalization were examined using the Cox proportional hazards regression model. The three groups were comparable for comorbid alcohol abuse/dependence, family history of severe psychiatric illness, years of education, and number of previous hospitalizations. No significant differences were noted among the three groups for the time to rehospitalization or the time to discontinuation. Age onset and number of previous admission were associated with risks of rehospitalization. This study suggests that the major depressive disorder, schizophrenia, and bipolar I disorder have comparable influences on time to rehospitalization and discontinuation from treatment and that earlier onset of illness and more previous hospitalizations are associated with higher risks of rehospitalization. Further prospective research is warranted. PMID:20494450

    Bipolar II disorder is characterized by alternating hypomanic and major depressive episode. We model the periodic mood variations of a bipolar II patient with a negatively damped harmonic oscillator. The medications administrated to the patient are modeled via a forcing function that is capable of stabilizing the mood variations and of varying their amplitude. We analyze analytically, using perturbation method, the amplitude and stability of limit cycles and check this analysis with numerical simulations.

    Treatment with lithium salts produces improvements in bipolar affective disorders. Up to date, the relationship between neurochemical and behavioural effects of lithium and its actions on intraneuronal free calcium ions is not well known. Some calcium antagonist drugs resulted active in the treatment of bipolar affective syndromes, with therapeutic effects similar to lithium salts. Some studies suggest that also lithium salts act as calcium antagonist at intraneuronal level. In this preliminary open study the activity of nimodipine, a selective neuronal calcium antagonist drug, was evaluated alone and in association with lithium salts in the treatment of rapid cycling bipolar manic-depressive illness. During three periods of 6 months 12 rapid cycling patients were treated with lithium salts, lithium salts plus nimodipine 30 mg x 3/day, nimodipine 30 mg x 3/day. The association of lithium with nimodipine resulted more effective than lithium alone or nimodipine alone in the reduction of episodes of affective disorder. These results suggest a probable sinergic activity of both treatments. Further studies will be necessary to confirm the mechanism of action, perhaps calcium antagonism, at the basis of therapeutic effects of both treatments. The results seem to confirm the hypothesis that a calcium-ionic disorders play a role in the pathogenesis of bipolar affective disorders.

    There is considerable debate over whether bipolar and related disorders that share common signs and symptoms, but are currently defined as distinct clinical entities in DSM-IV and ICD-10, may be better characterized as falling within a more broadly defined “bipolar spectrum”. With a spectrum view in mind, the possibility of broadening the diagnosis of bipolar disorder has been proposed. This paper discusses some of the rationale for an expanded diagnostic scheme from both clinical and research perspectives in light of potential drawbacks. The ultimate goal of broadening the diagnosis of bipolar disorder is to help identify a common etiopathogenesis for these conditions to better guide treatment. To help achieve this goal, bipolar researchers have increasingly expanded their patient populations to identify objective biological or endophenotypic markers that transcend phenomenological observation. Although this approach has and will likely continue to produce beneficial results, the upcoming DSM-IV and ICD-10 revisions will place increasing scrutiny on psychiatry’s diagnostic classification systems and pressure to re-evaluate our conceptions of bipolar disorder. However, until research findings can provide consistent and converging evidence as to the validity of a broader diagnostic conception, clinical expansion to a dimensional bipolar spectrum should be considered with caution.

    Anticipation refers to the increase in disease severity or decrease in age at onset in succeeding generations. This phenomenon, formerly ascribed to observation biases, correlates with the expansion of trinucleotide repeat sequences (TNRs) in some disorders. If present in bipolar affective disorder (BPAD), anticipation could provide clues to its genetic etiology. The authors compared age at onset and disease severity between two generations of 34 unilineal families ascertained for a genetic linkage study of BPAD. Life-table analyses showed a significant decrease in survival to first mania or depression from the first to the second generation (P <.001). Intergenerational pairwise comparisons showed both a significantly earlier age at onset (P < .001) and a significantly increased disease severity (P < .001) in the second generation. This difference was significant under each of four data-sampling schemes which excluded probands in the second generation. The second generation experienced onset 8.9-13.5 years earlier and illness 1.8-3.4 times more severe than did the first generation. In additional analyses, drug abuse, deaths of affected individuals prior to interview, decreased fertility, censoring of age at onset, and the cohort effect did not affect our results. The authors conclude that genetic anticipation occurs in this sample of unilineal BPAD families. These findings may implicate genes with expanding TNRs in the genetic etiology of BPAD. 24 refs., 1 fig., 1 tab.

    Goes, Fernando S

    2015-02-01

    Anxiety symptoms and syndromes are common in bipolar disorders, occurring in over half of all subjects with bipolar disorder type I. Despite methodological and diagnostic inconsistencies, most studies have shown a robust association between the presence of a broadly defined comorbid anxiety disorder and important indices of clinical morbidity in bipolar disorder, including a greater number of depressive episodes, worse treatment outcomes, and elevated risk of attempting suicide. Anxiety symptoms and/or syndromes often precede the onset of bipolar disorder and may represent a clinical phenotype of increased risk in subjects with prodromal symptoms. Although the causal relationship between anxiety and bipolar disorders remains unresolved, the multifactorial nature of most psychiatric phenotypes suggests that even with progress towards more biologically valid phenotypes, the "phenomenon" of comorbidity is likely to remain a clinical reality. Treatment studies of bipolar patients with comorbid anxiety have begun to provide preliminary evidence for the role of specific pharmacological and psychotherapeutic treatments, but these need to be confirmed in more definitive trials. Hence, there is an immediate need for further research to help guide assessment and help identify appropriate treatments for comorbid conditions.

Favourable effects of fever on mental disease have been noted throughout history. Today there is increasing evidence that immunological processes are involved in the pathophysiology of mental disorders. We present a case in which a patient with treatment resistant bipolar disorder mania seemingly recovered as a result of recurrent fever.

    There is an increasing body of literature fuelled by advances in high-resolution structural MRI acquisition and image processing techniques which implicates subtle neuroanatomical abnormalities in the aetiopathogenesis of bipolar disorder. This account reviews the main findings from structural neuroimaging research into regional brain abnormalities, the impact of genetic liability and mood stabilizing medication on brain structure in bipolar disorder, and the overlapping structural deviations found in the allied disorders of schizophrenia and depression. The manifold challenges extant within neuroimaging research are highlighted with accompanying recommendations for future studies. The most consistent findings include preservation of total cerebral volume with regional grey and white matter structural changes in prefrontal, midline and anterior limbic networks, non-contingent ventriculomegaly and increased rates of white matter hyperintensities, with more pronounced deficits in juveniles suffering from the illness. There is increasing evidence that medication has observable effects on brain structure, whereby lithium status is associated with volumetric increase in the medial temporal lobe and anterior cingulate gyrus. However, research continues to be confounded by the use of highly heterogeneous methodology and clinical populations, in studies employing small scale, low-powered, cross-sectional designs. Future work should investigate larger, clinically homogenous groups of patients and unaffected relatives, combining both categorical and dimensional approaches to illness classification in cross-sectional and longitudinal designs in order to elucidate trait versus state mechanisms, genetic effects and medication/illness progression effects over time.

    Abstract Bupropion is widely used for treating bipolar disorder (BD), and especially those with depressive mood, based on its good treatment effect, safety profile, and lower risk of phase shifting. However, increasing evidence indicates that the safety of bupropion in BD patients may not be as good as previously thought. The aim of this study was to summarize data on the treatment effect and safety profile of bupropion in the treatment of BD via a meta-analysis. Electronic search through PubMed and ClinicalTrials.gov was performed. The inclusion criteria were: (i) studies comparing changes in disease severity before and after bupropion treatment or articles comparing the treatment effect of bupropion in BD patients with those receiving other standard treatments; (ii) articles on clinical trials in humans. The exclusion criteria were (i) case reports/series, and (ii) nonclinical trials. All effect sizes from 10 clinical trials were pooled using a random effects model. We examined the possible confounding variables using meta-regression and subgroup analysis. Bupropion significantly improved the severity of disease in BD patients (P < 0.001), and the treatment effect was similar to other antidepressants/standard treatments (P = 0.220). There were no significant differences in the dropout rate (P = 0.285) and rate of phase shifting (P = 0.952) between BD patients who received bupropion and those who received other antidepressants. We could not perform a detailed meta-analysis of every category of antidepressant, nor could we rule out the possible confounding effect of concurrent psychotropics or include all drug side effects. Furthermore, the number of studies recruited in the meta-analysis was relatively small. Our findings reconfirm the benefits of bupropion for the treatment of bipolar depression, which are similar to those of other antidepressants. However, the rate of phase shifting with bupropion usage was not as low compared to other

    Manic-depressive (bipolar) illness is a serious psychiatric disorder with a strong genetic predisposition. The disorder is likely to be multifactorial and etiologically complex, and the causes of genetic susceptibility have been difficult to unveil. Lithium therapy is a widely used pharmacological treatment of manic-depressive illness, which both stabilizes the ongoing episodes and prevents relapses. A putative target of lithium treatment has been the inhibition of the myo-inositol monophosphatase (IMPase) enzyme, which dephosphorylates myo-inositol monophosphate in the phosphatidylinositol signaling system. Two genes encoding human IMPases have so far been isolated, namely myo-inositol monophosphatase 1 (IMPA1) on chromosome 8q21.13-21.3 and myo-inositol monophosphatase 2 (IMPA2) on chromosome 18p11.2. In the present study, we have scanned for DNA variants in the human IMPA1 and IMPA2 genes in a pilot sample of Norwegian manic-depressive patients, followed by examination of selected polymorphisms and haplotypes in a family-based bipolar sample of Palestinian Arab proband-parent trios. Intriguingly, two frequent single-nucleotide polymorphisms (-461C>T and -207T>C) in the IMPA2 promoter sequence and their corresponding haplotypes showed transmission disequilibrium in the Palestinian Arab trios. No association was found between the IMPA1 polymorphisms and bipolar disorder, neither with respect to disease susceptibility nor with variation in lithium treatment response. The association between manic-depressive illness and IMPA2 variants supports several reports on the linkage of bipolar disorder to chromosome 18p11.2, and sustains the possible role of IMPA2 as a susceptibility gene in bipolar disorder.

    A formal modeling approach was used to characterize decision-making processes in bipolar disorder. Decision making was examined in 28 bipolar patients (14 acute and 14 remitted) and 25 controls using the Iowa Gambling Task (Bechara et al., 1994), a decision-making task used for assessing cognitive impulsivity. To disentangle motivational and cognitive aspects of decision-making processes, we applied a formal cognitive model to the performance on the Iowa Gambling Task. The model has three parameters: The relative impact of rewards and punishments on evaluations, the impact of recent and past payoffs, and the degree of choice consistency. The results indicated that acute bipolar patients were characterized by low choice consistency, or a tendency to make erratic choices. Low choice consistency improved the prediction of acute bipolar disorder beyond that provided by cognitive functioning and self-report measures of personality and temperament. PMID:18848361

    Diagnosing a pediatric patient with bipolar disorder can pose a challenge for clinicians. Children typically do not present with the full criteria for a mood episode and may have symptoms of other disorders such as attention-deficit/hyperactivity disorder, oppositional defiant disorder, anxiety disorders, and other mood disorders, which may complicate the diagnostic process. By diligently interviewing parents and children about behaviors, thoroughly reviewing family histories, and systematically ruling out other disorders, clinicians can provide an accurate diagnosis for their pediatric patients.

    Multiple meningioma often can be clinically silent and may present with only psychiatric symptoms. We report a case of 43-year-old, right handed woman with a 23 year history of long standing bipolar affective disorder, who presented with a mixed episode with psychotic symptoms which did not respond to usual treatment and was further complicated with a different set of symptomatology. MRI brain revealed multiple dural based mass lesions identified to be multiple meningiomas. Patient's symptoms improved after gamma knife stereotactic radiosurgery for the multiple meningioma. Our finding illustrates the need to assess for brain lesions in presence of atypical symptoms, along with unresponsiveness to traditional management with psychotropic medications in patients with bipolar affective disorders.

    Fibroblasts from patients with Type I bipolar disorder (BPD) and their unaffected siblings were obtained from an Old Order Amish pedigree with a high incidence of BPD and reprogrammed to induced pluripotent stem cells (iPSCs). Established iPSCs were subsequently differentiated into neuroprogenitors (NPs) and then to neurons. Transcriptomic microarray analysis was conducted on RNA samples from iPSCs, NPs and neurons matured in culture for either 2 weeks (termed early neurons, E) or 4 weeks (termed late neurons, L). Global RNA profiling indicated that BPD and control iPSCs differentiated into NPs and neurons at a similar rate, enabling studies of differentially expressed genes in neurons from controls and BPD cases. Significant disease-associated differences in gene expression were observed only in L neurons. Specifically, 328 genes were differentially expressed between BPD and control L neurons including GAD1, glutamate decarboxylase 1 (2.5 fold) and SCN4B, the voltage gated type IV sodium channel beta subunit (-14.6 fold). Quantitative RT-PCR confirmed the up-regulation of GAD1 in BPD compared to control L neurons. Gene Ontology, GeneGo and Ingenuity Pathway Analysis of differentially regulated genes in L neurons suggest that alterations in RNA biosynthesis and metabolism, protein trafficking as well as receptor signaling pathways may play an important role in the pathophysiology of BPD.

    A new class of disease (including Huntington disease, Kennedy disease, and spinocerebellar ataxias types 1 and 3) results from abnormal expansions of CAG trinucleotides in the coding regions of genes. In all of these diseases the CAG repeats are thought to be translated into polyglutamine tracts. There is accumulating evidence arguing for CAG trinucleotide expansions as one of the causative disease mutations in schizophrenia and bipolar affective disorder. We and others believe that the TATA-binding protein (TBP) is an important candidate to investigate in these diseases as it contains a highly polymorphic stretch of glutamine codons, which are close to the threshold length where the polyglutamine tracts start to be associated with disease. Thus, we examined the lengths of this polyglutamine repeat in normal unrelated East Anglians, South African Blacks, sub-Saharan Africans mainly from Nigeria, and Asian Indians. We also examined 43 bipolar affective disorder patients and 65 schizophrenic patients. The range of polyglutamine tract-lengths that we found in humans was from 26-42 codons. No patients with bipolar affective disorder and schizophrenia had abnormal expansions at this locus. 22 refs., 1 tab.

    While the treatment of bipolar disorder (BD) is typically complex, the treatment of women with bipolar disorder is even more challenging because clinicians must also individualize treatment based on the potential for pregnancy, drug interactions with oral contraceptives, and an increased risk of endocrine diseases that can either impact the course of illness or become manifest with some treatments. Women with BD should be checked for hypothyroidism, and if prescribed antidepressants, carefully watched for rapid cycling or a mood switch to mania, hypomania, or a mixed state. Several medications interact with oral contraceptives or increase the risk of developing polycystic ovary syndrome. Consideration of possible pregnancy is essential, and should be planned in advance whenever possible. Rates of recurrence have been shown to be equal in pregnant and nonpregnant women with BD. Risks of medication to the fetus at various points of development must be balanced against the risks of not treating, which is also detrimental to both fetus and mother. The postpartum period is a time of especially high risk; as many as 40% to 67% of women with BD report experiencing a postpartum mania or depression. The decision to breastfeed must also take into account the adverse impact of sleep deprivation in triggering mood episodes. In order to best address these issues, clinicians must be familiar with the data and collaborate with the patient to assess risks and benefits for the individual women and her family. PMID:18689292

    Bipolar disorder (BD) is associated with abnormal circadian rhythms. In treatment responsive BD patients, lithium (Li) stabilizes mood and reduces suicide risk. Li also affects circadian rhythms and expression of 'clock genes' that control them. However, the extent to which BD, Li and the circadian clock share common biological mechanisms is unknown, and there have been few direct measurements of clock gene function in samples from BD patients. Hence, the role of clock genes in BD and Li treatment remains unclear. Skin fibroblasts from BD patients (N=19) or healthy controls (N=19) were transduced with Per2::luc, a rhythmically expressed, bioluminescent circadian clock reporter gene, and rhythms were measured for 5 consecutive days. Rhythm amplitude and period were compared between BD cases and controls with and without Li. Baseline period was longer in BD cases than in controls. Li 1 mM increased amplitude in controls by 36%, but failed to do so in BD cases. Li 10 mM lengthened period in both BD cases and controls. Analysis of clock gene variants revealed that PER3 and RORA genotype predicted period lengthening by Li, whereas GSK3β genotype predicted rhythm effects of Li, specifically among BD cases. Analysis of BD cases by clinical history revealed that cells from past suicide attempters were more likely to show period lengthening with Li 1 mM. Finally, Li enhanced the resynchronization of damped rhythms, suggesting a mechanism by which Li could act therapeutically in BD. Our work suggests that the circadian clock's response to Li may be relevant to molecular pathology of BD.

    From family, adoption, and twin studies it is clear that genetic factors play an important role in the etiology of bipolar disorder (McGuffin and Katz: The Biology of Depression, Gaskell, London, 1986). Recently Yoneda et al. reported an association between an allele (A4) of a VNTR marker (DXYS20) for the pseudoautosomal region and bipolar disorder in a Japanese population. In order to test for this association in a Caucasian population, we have typed a sample of 52 subjects with bipolar disorder and 61 normal controls. The bipolar subjects are probands of multiple incidence families. The normal controls are an epidemiologically ascertained sample of middle-aged, unrelated individuals. The two groups were matched for sex and ethnic background. There were no significant differences in the allele or genotype frequencies of DXYS20 between the two groups. In particular, there was no significant difference in the frequency of the A4 allele in normal controls and bipolar patients (0.377 vs. 0.317, respectively). The prevalence of the A4 allele in bipolar patients and normal controls was 0.567 and 0.622, respectively. We were not able to replicate the results of the 1992 Yoneda et al. study. 15 refs., 2 tabs.

    Antidepressant use seems to be problematic in bipolar disorder. The dopaminergic agent, bupropion, seems to be equally effective to serotoninergic agents but with greater safety. Methylphenidate is a stimulant medication that is sometimes used as an antidepressant in bipolar adults and is frequently used in children with comorbid bipolar and attention-deficit disorder. There are no data available for the safety of long-term methylphenidate in adults. A retrospective chart review of bipolar patients who received methylphenidate while attending a bipolar clinic was conducted. Data regarding side effects and symptoms were collected. Sixteen charts were reviewed. The mean duration of methylphenidate treatment was 14 months (+/-SD, +/-17.5 months; range, 1-60 months). Five had comorbid attention-deficit disorder, the remainder received the methylphenidate for depression. The mean dose was 16.3 mg/d (+/-SD, +/-8.7 mg/d; range, 5-40 mg/d). Several mild to moderate side effects were reported. Two patients (12.5%) discontinued methylphenidate because of adverse side effects. When available (44% of the sample), general assessment of function increased from (+/-SD) 48.3 +/- 9.9 to 69.3 +/- 10.6 (P = 0.006). Methylphenidate seems to be safe in the naturalistic setting. Controlled studies are needed to confirm its efficacy and safety in bipolar depression.

    Multiple meningioma often can be clinically silent and may present with only psychiatric symptoms. We report a case of 43-year-old, right handed woman with a 23 year history of long standing bipolar affective disorder, who presented with a mixed episode with psychotic symptoms which did not respond to usual treatment and was further complicated with a different set of symptomatology. MRI brain revealed multiple dural based mass lesions identified to be multiple meningiomas. Patient’s symptoms improved after gamma knife stereotactic radiosurgery for the multiple meningioma. Our finding illustrates the need to assess for brain lesions in presence of atypical symptoms, along with unresponsiveness to traditional management with psychotropic medications in patients with bipolar affective disorders.

    Bipolar disorder (BD) is a chronic psychiatric illness with an unknown etiology. Lithium is considered the cornerstone in the management of BD, though about 50-60 % of patients do not respond sufficiently to chronic treatment. Insulin-like growth factor 1 (IGF1) has been identified as a candidate gene for BD susceptibility, and its low expression has been suggested as a putative biomarker for lithium unresponsiveness. In this study, we examined the in vitro effects of insulin-like growth factor 1 (IGF-1) on lithium sensitivity in lymphoblastoid cell lines (LCLs) from lithium responder (R) and non-responder (NR) bipolar patients. Moreover, we evaluated levels of microRNA let-7c, a small RNA predicted to target IGF1. We found that exogenous IGF-1 added to serum-free media increased lithium sensitivity selectively in LCLs from NR BD patients. However, no significant differences were observed when comparing let-7c expression in LCLs from R vs. NR BD patients. Our data support a key role for IGF-1 in lithium resistance/response in the treatment of bipolar disorder.

    In treating bipolar disorder, specific psychotherapies in adjunct to pharmacotherapy have been shown to be effective in preventing new episodes and treating depressive episodes. Among those, interpersonal and social rhythm therapy (IPSRT) developed by Frank, amalgamation of interpersonal psychotherapy (IPT) with behavioral therapy focused on social rhythm has been shown to be an efficacious adjunct to mediation in preventing new episodes in bipolar I patients and in treating depression in bipolar I arid II disorder. IPSRT has also been shown to enhance total functioning, relationship functioning and life satisfaction among patients with bipolar disorder, even after pretreatment functioning and concurrent depression were covaried. IPSRT was designed to directly address the major pathways to recurrence in bipolar disorder, namely medication nonadherence, stressful life events, and disruptions in social rhythms. IPT, originated by Klerman et al., is a strategic time-limited psychotherapy focused on one or two of four current interpersonal problem areas (ie, grief, interpersonal role disputes, role transitions, and interpersonal dificits). In IPSRT, the fifth problem area "grief for the lost healthy self" has been added in order to promote acceptance of the diagnosis and the need for life-long treatment. Social rhythm therapy is a behavioral approach aiming at increasing regularity of social rhythms using the Social Rhythm Metric (SRM), a chart to record daily social activities including how stimulating they were, developed from observation that disruptions in social rhythms often trigger affective episodes in patients with bipolar disorder. IPSRT also appears to be a promising intervention for a subset of individuals with bipolar II depression as monotherapy for the acute treatment.

    Dementia and bipolar disorder have been traditionally considered two separate clinical entities. However, recent preclinical and clinical data in elderly people suggest that they are in fact related. Several theories have been put forward to interpret their relationship which could be summed up as follows: (1) Dementia could increase the risk for the emergence of bipolar symptoms, or (2) conversely, bipolar disorder might be associated with heightened risk for developing pseudodementia or dementia. (3) Alternatively, dementia, other brain diseases or drugs affecting brain function could lead to the combination of symptoms of dementia and bipolar disorder in elderly individuals. The two disorders demonstrate similarities with respect to their clinical expression (agitation, psychotic, mood and cognitive symptoms) and structural brain neuroimaging (enlarged lateral ventricles and white matter hyperintensities using magnetic resonance imaging-MRI). Despite the above similarities, the two disorders also have important differences. As expected, cognitive symptoms prevail in dementia and mood symptoms in bipolar disorder. In dementia but not in bipolar disorder there is evidence that brain structural abnormalities are diffuse and hippocampal volumes are smaller. Dementia and bipolar disorder present different abnormalities in functional brain neuroimaging. The pattern of "ventral" hyperactivity and "dorsal" hypoactivity in brain emotional circuits at rest is revealed in bipolar disorder but not dementia. With respect to their treatment, acetylcholinesterase inhibitors and memantine are indicated against cognitive symptoms in dementia and also improve behavioural and psychological symptoms appearing during the course of dementia. Lithium, anticonvulsants, antipsychotics and antidepressants are effective in the management of the acute episodes of bipolar disorder of younger adults, but there are not yet evidence-based data in elderly bipolar patients.

    Several studies have proven the effectiveness of psychoeducation in bipolar II disorder patients; however, simpler psychoeducation is needed in daily medical practice. Therefore, we devised a simple individual psychoeducation program, which involved 20-minute sessions spent reading a textbook aloud in the waiting time before examination. Here, we report a successful case of simple individual psychoeducation with a patient with bipolar II disorder, a 64-year-old woman who had misconceptions surrounding her mood due to 24 years of treatment for depression. Her perception of mood state, particularly mixed state, was dramatically changed, and her quality of life was improved after the simple individual psychoeducation. This case suggests that the simple individual psychoeducation could be effective for bipolar II disorder by improving understanding of the disease and by meeting different individual needs.

    Any given single nucleotide polymorphism (SNP) in a genome may have little or no functional impact. A biologically significant effect may possibly emerge only when a number of key SNP-related genotypes occur together in a single organism. Thus, in analysis of many SNPs in association studies of complex diseases, it may be useful to look at combinations of genotypes. Genes related to signal transmission, e.g., ion channel genes, may be of interest in this respect in the context of bipolar disorder. In the present study, we analysed 803 SNPs in 55 genes related to aspects of signal transmission and calculated all combinations of three genotypes from the 3×803 SNP genotypes for 1355 controls and 607 patients with bipolar disorder. Four clusters of patient-specific combinations were identified. Permutation tests indicated that some of these combinations might be related to bipolar disorder. The WTCCC bipolar dataset were use for replication, 469 of the 803 SNP were present in the WTCCC dataset either directly (n = 132) or by imputation (n = 337) covering 51 of our selected genes. We found three clusters of patient-specific 3×SNP combinations in the WTCCC dataset. Different SNPs were involved in the clusters in the two datasets. The present analyses of the combinations of SNP genotypes support a role for both genetic heterogeneity and interactions in the genetic architecture of bipolar disorder. PMID:21897858

    MRI-based reports of both abnormally increased and decreased amygdala volume in bipolar disorder (BD) have surfaced in the literature. Two major methodological weaknesses characterizing extant studies are treatment with medication and inaccurate segmentation of the amygdala due to limitations in spatial and tissue contrast resolution. Here, we acquired high-resolution images (voxel size=0.55×0.55×0.60mm) using a GE 3T MRI scanner, and a pulse sequence optimized for tissue contrast resolution. The amygdala was manually segmented by one rater blind to diagnosis, using coronal images. Eighteen unmedicated (mean medication-free period 11±10 months) BD subjects were age and gender matched with 18 healthy controls, and 17 medicated (lithium or divalproex) subjects were matched to 17 different controls. The unmedicated BD patients displayed smaller left and right amygdala volumes than their matched control group (p<0.01). Conversely, the BD subjects undergoing medication treatment showed a trend towards greater amygdala volumes than their matched HC sample (p=0.051). Right and left amygdala volumes were larger (p<0.05) or trended larger, respectively, in the medicated BD sample compared with the unmedicated BD sample. The two control groups did not differ from each other in either left or right amygdala volume. BD patients treated with lithium have displayed increased gray matter volume of the cortex and hippocampus relative to untreated BD subjects in previous studies. Here we extend these results to the amygdala. We raise the possibility that neuroplastic changes in the amygdala associated with BD are moderated by some mood stabilizing medications. PMID:19931399

    Importance It is estimated that more than half of those with serious mental illness smoke tobacco regularly. Standard courses of pharmacotherapeutic cessation aids improve short-term abstinence, but most who attain abstinence relapse rapidly after discontinuation of pharmacotherapy. Objective To determine whether smokers diagnosed with schizophrenia and bipolar disease have higher rates of prolonged tobacco abstinence with maintenance pharmacotherapy than with standard treatment. Design, Setting, and Participants Randomized, double-blind, placebo-controlled, parallel-group, relapse-prevention clinical trial conducted in 10 community mental-health centers. Of 247 smokers with schizophrenia or bipolar disease recruited from March 2008-April 2012, 203 received 12-weeks' open-label varenicline and cognitive behavioral therapy and 87 met abstinence criteria to enter the relapse prevention intervention. Interventions Participants who had 2 weeks or more of continuous abstinence at week 12 of open treatment were randomly assigned to receive cognitive behavioral therapy and double-blind varenicline (1 mg, 2 per day) or placebo from weeks 12 to 52. Participants then discontinued study treatment and were followed up to week 76. Main Outcomes and Measures Seven-day rate of continuous abstinence at study week 52, the end of the relapse-prevention phase, confirmed by exhaled carbon monoxide. Secondary outcomes were continuous abstinence rates for weeks 12 through 64 based on biochemically verified abstinence and weeks 12 through 76, based on self-reported smoking behavior. Results Sixty-one participants completed the relapse-prevention phase; 26 discontinued participation (7 varenicline, 19 placebo) and were considered to have relapsed for the analyses; 18 of these had relapsed prior to dropout. At week 52, point-prevalence abstinence rates were 60% in the varenicline group (24 of 40) vs 19% (9 of 47) in the placebo group (odds ratio [OR], 6.2; 95% CI, 2.2-19.2; P < .001). From

    Bipolar disorder is a serious mental illness characterized by alternating periods of elevated and depressed mood. Sleep disturbances in bipolar disorder are present during all stages of the condition and exert a negative impact on overall course, quality of life, and treatment outcomes. We examine the partnership between circadian system (process C) functioning and sleep-wake homeostasis (process S) on optimal sleep functioning and explore the role of disruptions in both systems on sleep disturbances in bipolar disorder. A convergence of evidence suggests that sleep problems in bipolar disorder result from dysregulation across both process C and process S systems. Biomarkers of depressive episodes include heightened fragmentation of rapid eye movement (REM) sleep, reduced REM latency, increased REM density, and a greater percentage of awakenings, while biomarkers of manic episodes include reduced REM latency, greater percentage of stage I sleep, increased REM density, discontinuous sleep patterns, shortened total sleep time, and a greater time awake in bed. These findings highlight the importance of targeting novel treatments for sleep disturbance in bipolar disorder. PMID:27418862

    This study examines rates of co-morbid mental disorders and indicators of the course of illness among individuals with bipolar disorder and cannabis use disorders (CUD). Data were drawn from the National Epidemiological Survey of Alcohol and Related Conditions (NESARC Wave 1, 2001-2002), a nationally representative sample of adults living in the United States. Among individuals with lifetime prevalence of bipolar disorder (N=1905) rates of CUD in the past 12 months were 7.2%, compared to 1.2% in the general population. Logistic regression models adjusting for sociodemographic variables indicated that individuals with bipolar disorder and co-occurring CUD were at increased risk for nicotine dependence (Adjusted Odds Ratio (AOR)=3.8), alcohol (AOR=6.6) and drug (AOR=11.9) use disorders, as well as antisocial personality disorder (AOR=2.8) compared to those without CUD. Among individuals with co-occurring CUD, age of onset of bipolar disorder was significantly lower and median number of manic, hypomanic and depressive episodes per year was significantly greater compared to individuals without CUD. Co-occurring CUD is associated with significant co-morbidities and a more severe course of illness among individuals with bipolar disorder. Comprehensive evaluation of patients with bipolar disorder should include a systematic assessment of CUD.

    Frequently used in a pejorative sense, "disease mongering" connotes a widening of the diagnostic boundaries of illness. Pharmaceutical companies conduct disease awareness campaigns on the pretext of educating the public about the prevention of illness or the promotion of health. Encouraged by disease awareness advertisements, people gradually become filled with concern that they are ill and need medical treatment. As a result, pharmacotherapy is increasingly being applied to ever-milder conditions, leading to potentially unnecessary medication, wasted resources, and even adverse side effects. Among all fields of clinical medicine, psychiatry is undoubtedly the most vulnerable to the danger of disease mongering. In Japan, depression provides the most drastic example of the impact of disease awareness campaigns on the number of patients seeking treatment. Until the late 1990s, Japanese psychiatrists focused almost exclusively on psychosis and endogenous depression, the latter being severe enough to require conventional forms of antidepressants, known as tricyclic antidepressants, and even hospitalization. At this time, people's attitude toward depression was generally unfavorable. Indeed, the Japanese word for clinical depression, utubyo, has a negative connotation, implying severe mental illness. This situation, however, changed immediately after fluvoxiamine (Luvox-Fujisawa, Depromel-Meiji Seika), the first selective serotonin re-uptake inhibitor (SSRI) to receive approval in Japan, was introduced in 1999. In order to aid the drug's acceptance by the Japanese public, pharmaceutical companies began using the catchphrase kokoro no kaze, which literally means "a cold of the soul". Thus armed with this phrase, the pharmaceutical industry embarked on a campaign to lessen the stigma surrounding depression. According to national data from the Ministry of Health and Welfare, the number of patients with a diagnosis of mood disorder increased from 327,000 in 1999 to 591

Challenges regarding the diagnosis of BD will be discussed, in addition to important distinctions with other childhood disorders, including other bipolar spectrum disorders; major depressive disorder; dysthymia; disruptive mood dysregulation disorder (DMDD); attention-deficit/hyperactivity disorder (ADHD) and other disruptive behavioral disorders; anxiety disorders, including post-traumatic stress disorder (PTSD); psychotic disorders; autism spectrum disorders; substance use disorders; and borderline personality disorder. The review concludes with a comment on past research limitations and future directions in the field. PMID:25315116

    Neuroleptics can induce not only physical adverse effects but also mental effects that produce deficit status in thought, affect, cognition, and behavior. This condition is known as neuroleptic-induced deficit syndrome (NIDS), which includes apathy, lack of initiative, anhedonia, indifference, blunted affect, and reduced insight into disease. Although this old concept now appears almost forgotten, neuroleptics, whether typical or atypical, can make depression or bipolar disorder resemble other more refractory conditions, readily leading to mistaken diagnosis and inappropriate treatment. The authors describe three cases of NIDS superimposed on depressive phase in bipolar disorder with psychosis, where the attending psychiatrist’s failure to recognize NIDS prevented patients from receiving effective treatment and achieving remission. All cases achieved remission after reduction of neuroleptics and intensive therapy, including electroconvulsive therapy, for bipolar depression. The concept of NIDS was originally introduced for schizophrenia, and it has rarely been highlighted in other diseases. In recent years, however, atypical antipsychotics are being more often administered to patients with bipolar disorder. Psychiatrists, therefore, should also remember and exercise caution regarding NIDS in the pharmacotherapy of bipolar disorder with and without psychosis. The authors believe that the concept of NIDS needs to be reappraised in current psychiatry. PMID:26893564

    Frontotemporal dementia is a cause of behavioral disturbance that usually appears in individuals between 45 and 65 years of age. The authors present the case of a 65-year-old patient that illustrates how frontotemporal dementia can be misdiagnosed based on a behavioral pattern that suggests the presence of a primary mood disorder. Early accurate diagnosis of frontotemporal dementia and subsequent supportive measures can allow patients and families to make important decisions about business and legal affairs and how to spend remaining leisure time in the most meaningful and enjoyable way possible.

    Lithium carbonate is considered to be a first-line treatment for bipolar disorder; however, this drug has a narrow therapeutic window, and lithium intoxication is commonly induced by various drugs interaction and situations. We herein report a case of lithium intoxication induced by the administration of an antihypertensive agent targeting the angiotensin 1 (AT1) subtype of the angiotensin II receptor in a 65-year-old woman with a 40-year history of bipolar disorder type 1, and 1-year history of essential hypertension. Her bipolar disorder had been well-controlled with 600 mg/day of lithium carbonate for more than 10 years. She was later diagnosed with hypertension and the AT1 receptor blocker, azilsartan was thereafter administrated on a daily basis. After 3 weeks of azilsartan administration, she presented with progressive action tremor and showed a gradual deterioration of her physical state. Four months after the start of azilsartan administration, she presented with alternating episodes of diarrhea and constipation. Two weeks before admission to our hospital, she presented with mild consciousness disturbances, myoclonus, truncal ataxia, and appetite loss. She was diagnosed to have lithium intoxication based on an elevated serum lithium concentration of 3.28 mEq/l.It is therefore important to evaluate the serum lithium concentration after the administration of antihypertensive agents, and consider lithium-antihypertensive agent interactions when selecting antihypertensive agents in elderly patients receiving long-term lithium carbonate treatment.

    We have tested the hypothesis that DNA markers in the MAOA gene show allelic association with bipolar affective disorder. Eighty-four unrelated Caucasian patients with DSM III-R bipolar disorder and 84 Caucasian controls were typed for three markers in MAOA: a dinucleotide repeat in intron 2, a VNTR in intron 1, and an Fnu4HI RFLP in exon 8. No evidence for allelic association was observed between any of the markers and bipolar disorder. 9 refs., 1 tab.

    Background Thyroid disorders have long been associated with psychiatric illness, often with symptoms suggestive of mood disorders. The most common clinical features associated with hyperthyroidism are anxiety and depression. The risk of bipolar disorders, especially bipolar mania, among patients with thyroid disorders has not been well characterized. Objective We explored the relationship of hyperthyroidism and the subsequent development of bipolar disorders, and examined the risk factors for bipolar disorders in patients with hyperthyroidism. Methods We identified patients who were diagnosed with hyperthyroidism between 2000 and 2010 in the Taiwan National Health Insurance Research Database. A comparison cohort without hyperthyroidism was matched based on age, sex, and comorbidities. The occurrence of bipolar disorders was evaluated in both cohorts based on diagnosis and the use of mood stabilizer drugs. Results The hyperthyroidism cohort consisted of 21, 574 patients, and the comparison cohort consisted of 21, 574 matched control patients without hyperthyroidism. The incidence of bipolar disorders (incidence rate ratio [IRR], 2.31, 95% CI 1.80–2.99, P<.001) was higher for the hyperthyroidism patients than the control patients. Multivariate, matched regression models showed that women (HR 2.02, 95% CI 1.34–3.05, P = .001), patients with alcohol use disorders (HR 3.03, 95% CI 1.58–5.79, P = .001), and those with asthma (HR 1.70, 95% CI 1.18–2.43, P = .004) were independent risk factors for the development of bipolar disorders in hyperthyroidism patients. Conclusions Although a possibility that the diagnosis of bipolar disorders in this study actually includes "bipolar disorders due to hyperthyroidism" cannot be excluded, this study suggests that hyperthyroidism may increase the risk of developing bipolar disorders.

    Bipolar disorder, characterised by extreme cyclical variations in mood between depression and mania, is a common, debilitating and sometimes fatal psychiatric condition with an unclear aetiology. In this paper we propose a hypothesis for the development of bipolar disorder through which neuroplastic changes in response to an index depressive episode leads to the amplification of subthreshold pleasurable stimuli that then drive conversion into a manic state. This ‘pleasure deafferentation hypothesis’ is reached through a discussion of the neuroscientific basis of deafferentation at the level of the neuron and its role in the development of various neurological and psychiatric phenomena before a case for deafferentation as applied to bipolar disorder is justified and its implications discussed.

    Bipolar patients are at a higher risk of developing metabolic disorders. Cardiovascular morbidity and mortality is twice the rate reported in the population. Antipsychotic medication increases the risk of metabolic abnormalities. However, bipolar disorder and schizophrenia have a similarly increased mortality from cardiovascular causes of death, although bipolar patients medicate with antipsychotic drugs to a much smaller extent than schizophrenic patients. Bipolar disorder and schizophrenia share substantial genetic risk components; thus, increased metabolic abnormalities is hypothesized to be an effect of specific sets of metabolic risk genes, which might overlap with the metabolic risk genes in schizophrenia. This study reports that a functional genetic variant of MTNR1B, previously implicated in the impairment of glucose-stimulated insulin release also in schizophrenia, was associated with elevated fasting glucose levels in bipolar patients and controls. This finding suggests that the MTNR1B-dependent vulnerability for elevated fasting plasma glucose levels is shared between bipolar disorder and schizophrenia. PMID:26991397

    Bipolar disorder is a serious psychiatric disorder, with a high heritability and unknown pathogenesis. Recent genome-wide association studies have identified the first loci, implicating genes such as CACNA1C and ANK3. The genes highlight several pathways, notably calcium signalling, as being of importance. Molecular studies suggest that the risk variants impact on gene regulation and expression. Preliminary studies using reprogrammed patient-derived cells report alterations in the transcriptome and in cellular adhesion and differentiation. Mouse models show that genes involved in circadian biology, acting via dopaminergic effects, reproduce aspects of the bipolar phenotype. These findings together represent significant advances in identification of the genetic and molecular basis of bipolar disorder, yet we are still far from an integrated, evidence-based understanding of its aetiopathogenesis.

    Although schizophrenia (SZ) and bipolar disorder (BD) share some clinical features such as psychotic symptoms and cognitive dysfunctions, little is known about possible pathophysiological similarities between both diseases. Therefore, we investigated the potential topographical overlap and segregation of cortical thickness abnormalities in SZ and BD patients. We analyzed 3D-anatomical magnetic resonance imaging datasets with the FreeSurfer 5.1.0 software to examine cortical thickness and volumes in three groups of participants: n=34 BD patients, n=32 SZ patients and n=38 healthy controls. We observed similar bilateral cortical thickness reductions in BD and SZ patients predominantly in the pars opercularis of the inferior frontal gyrus and in the anterior and posterior cingulate. We also found disease-specific cortical reductions in the orbitofrontal cortex for BD patients and in dorsal frontal and temporal areas for SZ. Furthermore, inferior frontal gyrus cortical thinning was associated with deficits in psychomotor speed and executive functioning in SZ patients and with age at onset in both groups. Our findings support the hypothesis that thinning of the frontal cortex may represent a biological feature shared by both disease groups. The associations between cognitive deficits and the reported findings in SZ and to a lesser degree in BD patients add to the functional relevance of our results. However, further studies are needed to corroborate a model of shared pathophysiological disease features across BD and SZ. PMID:26876312

    Abstract Significant cognitive dysfunction has been recognized as an important state and trait feature of bipolar disorder. In this article, longitudinal studies comparing cognitive performance in bipolar disorder patients and healthy controls are reviewed. In contrast to cross-sectional reports, current longitudinal research findings do not support a progressive cognitive decline over time. However, a higher within-person instability in cognitive performance was found relative to controls. The need for larger samples remains, as well as for longer and more frequent observations.

    In this Letter, we use a synchronization scheme on two bipolar disorder models consisting of a strong nonlinear system with multiplicative excitation and a nonlinear oscillator without parametric harmonic forcing. The stability condition following our control function is analytically demonstrated using the Lyapunov theory and Routh-Hurwitz criteria, we then have the condition for the existence of a feedback gain matrix. A convenient demonstration of the accuracy of the method is complemented by the numerical simulations from which we illustrate the synchronized dynamics between the two non-identical bipolar disorder patients.

    Pharmacotherapy is an important component of treatment for children and adolescents with bipolar disorder. The body of evidence supporting safe and effective treatments in this population is growing. Available data provide information on the risks and benefits of pharmacologic agents used for acute manic, mixed, and depressive episodes as well as for maintenance treatment. Lithium, anticonvulsants, and antipsychotics comprise the armamentarium for treating pediatric bipolar disorder. When selecting treatment, clinicians must consider the efficacy and side effect profile of potential pharmacotherapies, as well as the patient's history, including the presence of comorbidities, in order to develop a treatment plan that will ensure optimal outcomes.

    Bipolar disorder is characterized by exacerbations of opposite mood polarity, ranging from manic to major depressive episodes. In the current nosological system of the Diagnostic and Statistical Manual - 5(th) edition (DSM-5), it is conceptualized as a spectrum disorder consisting of bipolar disorder type I, bipolar disorder type II, cyclothymic disorder, and bipolar disorder not otherwise specified. Treatment of all phases of this disorder is primarily with mood stabilizers, but many patients either show resistance to the conventional mood stabilizing medications or are intolerant to their side-effects. In this setting, second-generation antipsychotics have gained prominence as many bipolar subjects who are otherwise treatment refractory show response to these agents. Aripiprazole is a novel antipsychotic initially approved for the treatment of schizophrenia but soon found to be effective in bipolar disorder. This drug is well studied, as randomized controlled trials have been conducted in various phases of bipolar disorders. Aripiprazole exhibits the pharmacodynamic properties of partial agonism, functional selectivity, and serotonin-dopamine activity modulation - the new exemplars in the treatment of major psychiatric disorders. It is the first among a new series of psychotropic medications, which now also include brexpiprazole and cariprazine. The current review summarizes the data from controlled trials regarding the efficacy and safety of aripiprazole in adult bipolar patients. On the basis of this evidence, aripiprazole is found to be efficacious in the treatment and prophylaxis of manic and mixed episodes but has no effectiveness in acute and recurrent bipolar depression.

    In bipolar disorder, levels of insight vary as a function of the mood state and appear to influence pharmacology compliance, quality of life, the presence of suicidal ideations, and aggressive behavior. To establish a comparison among different mood states in bipolar with regard to level of insight. Forty-eight patients were evaluated in different affective states (i.e., euthymia, mania, depression, and mixed state). Identifying information, sociodemographic data, and clinical records were recorded. The following scales were applied: Hamilton Depression Scale, Young Mania Rating Scale, Positive and Negative Syndrome Scale positive symptoms subscale, and Global Assessment of Functioning and Clinical Global Impressions Scale for use in bipolar disorder. Insight was evaluated using items 11 and 17 of the Young Mania Rating Scale and Hamilton Depression Scale, respectively. Insight in bipolar disorder was found to be more compromised during manic phases and mixed episodes than during periods of depression or euthymia. The factors associated with lower levels of insight were the following: shorter illness duration, older age, and greater severity in mania; the female gender and older age in depression; and shorter illness duration and more severe depressive symptoms in mixed episodes. In the same individual, levels of insight vary as a function of the affective state over the course of bipolar disorder and appear to be influenced by several clinical variables.

    Rates of misdiagnosis between major depressive disorder and bipolar disorder have been reported to be substantial, and the consequence of such misdiagnosis is likely to be a delay in achieving effective control of symptoms, in some cases spanning many years. Particularly in the midst of a depressive episode, or early in the illness course, it may be challenging to distinguish the 2 mood disorders purely on the basis of cross-sectional features. To date, no useful biological markers have been reliably shown to distinguish between bipolar disorder and major depressive disorder.

    The concept of prevention is not new to psychiatry and has long been recognized in general medicine. Recent evidence has highlighted that early pharmacological and psychosocial treatment dramatically ameliorates poor prognosis and outcome for individuals with psychotic disorders, reducing conversion rates to full-blown illness and decreasing symptom severity. Nevertheless, despite the many recent advances in our thinking about early intervention, the need for early intervention in bipolar disorder (BPD) is an area that has been relatively neglected. This review attempts to synthesize what is currently known about early intervention in BPD. We discuss methodological issues pertaining to this topic, review clinical studies that focus on high-risk subjects as well as first-episode patients, and review findings from brain imaging studies in the offspring of individuals with BPD as well as in first-episode patients. A companion article discusses the cellular and molecular mechanisms of action of agents with neurotrophic and neuroplastic properties, with a particular emphasis on lithium and valproate.

    Neural models of anatomical and functional alterations have been proposed for bipolar disorders (BD). However, studies in affected patients do not allow disentangling alterations linked to the liability to BD from those associated with the evolution, medication and comorbidities of BD. Explorations in high risk subjects allow the study of these risk markers. We reported and summarized all functional magnetic resonance imaging (fMRI) studies focusing on first-degree relatives of BD patients. We found 29 studies reporting neural correlates of working memory (WM), emotional processing, executive functions and resting state in relatives of BD patients, compared to healthy subjects. Overall, the same regions that have been involved in patients, such as the inferior frontal gyrus and limbic areas, seem to be functionally altered in high-risk subjects. We conclude that the same brain regions already implicated in the pathophysiology of the disease such as the amygdala are also associated with the risk of BD. However longitudinal studies are required to understand their implication in the transition to BD.

    The serotonin transporter (HTT) is an important candidate gene for the genetic transmission of bipolar disorder. It is the site of action of many antidepressants, and plays a key role in the regulation of serotonin neurotransmission. Many studies of affectively ill patients have found abnormalities in serotonin metabolism, and dysregulation of the transporter itself. The human serotonin transporter has been recently cloned and mapped to chromosome 17. We have identified a PstI RFLP at the HTT locus, and here report our examination of this polymorphism for possible linkage to bipolar disorder. Eighteen families were examined from three populations: the Old Order Amish, Iceland, and the general North American population. In addition to HTT, three other microsatellite markers were examined, which span an interval known to contain HTT. Linkage analyses were conducted under both dominant and recessive models, as well as both narrow (bipolar only) and broad (bipolar + recurrent unipolar) diagnostic models. Linkage could be excluded to HTT under all models examined. Linkage to the interval spanned by the microsatellites was similarly excluded under the dominant models. In two individual families, maximum lod scores of 1.02 and 0.84 were obtained at D17S798 and HTT, respectively. However, these data overall do not support the presence of a susceptibility locus for bipolar disorder near the serotonin transporter. 20 refs., 2 tabs.

    OBJECTIVE To investigate family physicians’ experience in diagnosing and managing bipolar disorder, how they rate their undergraduate and postgraduate training in this area, and what they think they need to learn in the future. DESIGN Survey questionnaire. SETTING Family practices in London, Ont. PARTICIPANTS Random sample of 297 family physicians. MAIN OUTCOME MEASURES Physicians’ experience in diagnosing and managing patients with bipolar disorder, rating of their undergraduate and postgraduate training in this area, and thoughts about what they need to learn in the future. RESULTS Of 297 surveys sent out, 147 (49.5%) were returned. Male respondents accounted for 62%, and female respondents 37%, of completed surveys. Average year of graduation from medical school was 1979. The most common response for level of experience in diagnosing and treating bipolar disorders was “somewhat comfortable.” Physicians frequently reported screening for symptoms of mood disorders (42%), and most of them were sharing care with other professionals (88%). Undergraduate training was rated as poor (42%) or satisfactory (46%), and postgraduate training was rated as poor (42%) or satisfactory (44%). Physicians thought they needed more education in issues of diagnosis and pharmacotherapy. CONCLUSION Family physicians were only somewhat comfortable with diagnosing and managing bipolar disorders, and most thought their undergraduate and graduate training in this area had been, at best, satisfactory. They expressed a need for more education in the areas of diagnosis and pharmacotherapy. PMID:16926928

    Multi-layer perceptron (MLP) neural network belongs to multi-layer feedforward neural network, and has the ability and characteristics of high intelligence. It can realize the complex nonlinear mapping by its own learning through the network. Bipolar disorder is a serious mental illness with high recurrence rate, high self-harm rate and high suicide rate. Most of the onset of the bipolar disorder starts with depressive episode, which can be easily misdiagnosed as unipolar depression and lead to a delayed treatment so as to influence the prognosis. The early identifica- tion of bipolar disorder is of great importance for patients with bipolar disorder. Due to the fact that the process of early identification of bipolar disorder is nonlinear, we in this paper discuss the MLP neural network application in early identification of bipolar disorder. This study covered 250 cases, including 143 cases with recurrent depression and 107 cases with bipolar disorder, and clinical features were statistically analyzed between the two groups. A total of 42 variables with significant differences were screened as the input variables of the neural network. Part of the samples were randomly selected as the learning sample, and the other as the test sample. By choosing different neu- ral network structures, all results of the identification of bipolar disorder were relatively good, which showed that MLP neural network could be used in the early identification of bipolar disorder.

By choosing different neu- ral network structures, all results of the identification of bipolar disorder were relatively good, which showed that MLP neural network could be used in the early identification of bipolar disorder.

  16. [Bipolar disorders and self-stigma].

    PubMed

    Despite wide media coverage in recent years, the stigmatization of people with bipolar disorder still exists. Bipolar people also have their own tendency to self-stigmatize that is to integrate their beliefs, prejudices and stigmatizing behaviors. The consequences are important: shame, guilt, withdrawal and renunciation to lead one's own life according to personal values increasing therefore the risk of mood relapses. Self-stigma is rarely assessed in clinical practice and few strategies have been designed to face them efficiently. Recognizing self-stigmatizing beliefs and challenging them are the first steps of this vast endeavour. PMID:26591079

    This paper gives an overview of psychoanalytic contributions to the understanding of suicidal behavior in bipolar patients. Although little specific literature is available, many authors have contributed to the understanding of these patients' psychodynamics and suicidality in various papers. Different points of emphasis are described, among these are defensive strategies, narcissistic personality structure, and dealing with intense feelings such as object loss. Using detailed case descriptions, the inner world of bipolar patients as it relates to their suicidality, along with the appropriate psychoanalytically oriented approach to treatment, are highlighted.

    Background Studies have suggested that chronic inflammation plays an essential role in the pathophysiology of both rheumatoid arthritis (RA) and bipolar disorder. The most common clinical features associated with RA are anxiety and depression. The risk of bipolar disorder among patients with RA has not been characterized adequately. Objective To determine the association between RA and the subsequent development of bipolar disorder and examine the risk factors for bipolar disorder among patients with RA. Methods We identified patients who were diagnosed with RA in the Taiwan National Health Insurance Research Database. A comparison cohort was created by matching patients without RA with those with RA according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts. Results The RA cohort consisted of 2,570 patients, and the comparison cohort consisted of 2,570 matched control patients without RA. The incidence of bipolar disorder (incidence rate ratio  = 2.13, 95% confidence interval [CI]  = 1.12–4.24, P =  .013) was higher among patients with RA than among control patients. Multivariate, matched regression models revealed that asthma (hazard ratio [HR]  = 2.76, 95% CI 1.27–5.96, P =  .010), liver cirrhosis (HR  = 3.81, 95% CI  = 1.04–14.02, P =  .044), and alcohol use disorders (HR  = 5.29, 95% CI  = 1.71–16.37, P =  .004) were independent risk factors for the development of bipolar disorder among patients with RA. Conclusion RA might increase the incidence of bipolar disorder development. Based on our data, we suggest that, following RA diagnosis, greater attention be focused on women with asthma, liver cirrhosis, and alcohol use disorder. Prospective clinical studies of the relationship between RA and bipolar disorder are warranted. PMID:25229610

  20. Brain oscillations in bipolar disorder and lithium-induced changes

    Electroencephalography (EEG) studies in patients with bipolar disorder have revealed lower amplitudes in brain oscillations. The aim of this review is to describe lithium-induced EEG changes in bipolar disorder and to discuss potential underlying factors. A literature survey about lithium-induced EEG changes in bipolar disorder was performed. Lithium consistently enhances magnitudes of brain oscillations in slow frequencies (delta and theta) in both resting-state EEG studies as well as event-related oscillations studies. Enhancement of magnitudes of beta oscillations is specific to event-related oscillations. Correlation between serum lithium levels and brain oscillations has been reported. Lithium-induced changes in brain oscillations might correspond to lithium-induced alterations in neurotransmitters, signaling cascades, plasticity, brain structure, or biophysical properties of lithium. Therefore, lithium-induced changes in brain oscillations could be promising biomarkers to assess the molecular mechanisms leading to variability in efficacy. Since the variability of lithium response in bipolar disorder is due to the genetic differences in the mechanisms involving lithium, it would be highly promising to assess the lithium-induced EEG changes as biomarkers in genetic studies.

    Borderline personality disorder (BPD) and bipolar disorder (types I and II) are frequently confused because of their symptomatic overlap. Although affective instability is a prominent feature of each, the pattern is entirely different. BPD is characterized by transient mood shifts that occur in response to interpersonal stressors, whereas bipolar disorder is associated with sustained mood changes. These disorders can be further distinguished by comparing their phenomenology, etiology, family history, biological studies, outcome, and response to medication. Their distinction is of great clinical importance because misdiagnosis can deprive the patient of potentially effective treatment, whether it is psychotherapy for BPD or medication for bipolar disorder. On the basis of a comprehensive literature review, guidelines for differential diagnosis are suggested, and priorities for further research are recommended.

    Objective The aims of this study were to determine whether childhood maltreatment contributes to the occurrence of major depressive disorder (MDD) with bipolarity, and whether there is a relationship between central serotonergic activity, as assessed using loudness dependence of auditory evoked potentials (LDAEP), and childhood maltreatment. Methods Thirty-five MDD patients were stratified according to the presence or absence of childhood trauma into two subgroups, childhood trauma (CT) and no childhood trauma (NCT), using the Korean version of the Childhood Trauma Questionnaire (K-CTQ). The CT group was subjected to further analysis. Several psychometric ratings were also applied. In addition, auditory processing for the loudness dependence of auditory evoked potentials (LDAEP), which was used as a marker of serotonergic activity, was measured before beginning medication. Results There was a significant difference in total Korean Bipolar Spectrum Disorder Scale score between the CT and NCT groups (t=-2.14, p=0.04). The total K-CTQ score was positively correlated with the total Beck Scale for Suicidal Ideation (BSS) score (r=0.36, p=0.036). In particular, emotional abuse was positively correlated with the total Barratt Impulsiveness Scale (r=0.38, p=0.026), BSS (r=0.38, p=0.025), and Hamilton Depression Rating Scale (HAMD) (r=0.36, p=0.035) scores. There was also a positive correlation between LDAEP and total Hypomania Personality Scale (r=0.49, p=0.02) and HAMD (r=0.58, p=0.004) scores within CT group. Conclusion The findings of this study support that there is a relationship between childhood maltreatment and bipolarity in patients with MDD. PMID:27081379

    Objective Early-onset bipolar disorder is thought to be a particularly severe variant of the illness. Continuity with the adult form of illness remains unresolved, but preliminary evidence suggests similar biological underpinnings. Recently, we observed localized hippocampal decreases in unmedicated adults with bipolar disorder that were not detectable with conventional volumetric measures. Using the same three-dimensional mapping methods, we sought to investigate whether a similar pattern exists in adolescents with bipolar disorder. Method High-resolution brain magnetic resonance images were acquired from 16 adolescents meeting DSM-IV criteria for bipolar disorder (mean age 15.5 ± 3.4 years, 50% female) and 20 demographically matched, typically developing control subjects. Three-dimensional parametric mesh models of the hippocampus were created from manual tracings of the hippocampal formation. Results Controlling for total brain volume, total hippocampal volume was significantly smaller in adolescent patients with bipolar disorder relative to controls (by 9.2%). Statistical mapping results, confirmed by permutation testing, revealed significant localized deformations in the head and tail of the left hippocampus in adolescents with bipolar disorder, relative to normal controls. In addition, there was a significant positive correlation between hippocampal size and age in patients with bipolar disorder, whereas healthy controls showed an inverse relation. Discussion Localized hippocampal deficits in adolescent patients with bipolar disorder suggest a possible neural correlate for memory deficits observed in this illness. Moreover, age-related increases in hippocampal size in patients with bipolar disorder, not observed in healthy controls, may reflect abnormal developmental mechanisms in bipolar disorder. This possibility must be confirmed by longitudinal studies. PMID:18356767

  6. Genetic relationships between schizophrenia, bipolar disorder, and schizoaffective disorder.

    2014-05-01

    There is substantial evidence for partial overlap of genetic influences on schizophrenia and bipolar disorder, with family, twin, and adoption studies showing a genetic correlation between the disorders of around 0.6. Results of genome-wide association studies are consistent with commonly occurring genetic risk variants, contributing to both the shared and nonshared aspects, while studies of large, rare chromosomal structural variants, particularly copy number variants, show a stronger influence on schizophrenia than bipolar disorder to date. Schizoaffective disorder has been less investigated but shows substantial familial overlap with both schizophrenia and bipolar disorder. A twin analysis is consistent with genetic influences on schizoaffective episodes being entirely shared with genetic influences on schizophrenic and manic episodes, while association studies suggest the possibility of some relatively specific genetic influences on broadly defined schizoaffective disorder, bipolar subtype. Further insights into genetic relationships between these disorders are expected as studies continue to increase in sample size and in technical and analytical sophistication, information on phenotypes beyond clinical diagnoses are increasingly incorporated, and approaches such as next-generation sequencing identify additional types of genetic risk variant.

    Bipolar disorder is a heterogeneous condition with myriad clinical manifestations and many comorbidities leading to severe disabilities in the biopsychosocial realm. The objective of this review article was to underline recent advances in knowledge regarding the neurobiology of bipolar disorder. A further aim was to draw attention to new therapeutic targets in the treatment of bipolar disorder. To accomplish these goals, an electronic search was undertaken of the PubMed database in August 2015 of literature published during the last 10 years on the pathophysiology of bipolar disorder. A wide-ranging evaluation of the existing work was done with search terms such as "mood disorders and biology," "bipolar disorder and HPA axis," "bipolar disorder and cytokines," "mood disorders and circadian rhythm," "bipolar disorder and oxidative stress," etc. This endeavor showed that bipolar disorder is a diverse condition sharing neurobiological mechanisms with major depressive disorder and psychotic spectrum disorders. There is convincing evidence of crosstalk between different biological systems that act in a deleterious manner causing expression of the disease in genetically predisposed individuals. Inflammatory mediators act in concert with oxidative stress to dysregulate hormonal, metabolic, and circadian homeostasis in precipitating and perpetuating the illness. Stress, whether biologically or psychologically mediated, is responsible for the initiation and progression of the diathesis. Bipolar spectrum disorders have a strong genetic component; severe life stresses acting through various paths cause the illness phenotype. PMID:26865997

    Bipolar mixed states combine depressive and manic features, presenting diagnostic and treatment challenges and reflecting a severe form of the illness. DSM-IV criteria for a mixed state require combined depressive and manic syndromes, but a range of mixed states has been described clinically. A unified definition of mixed states would be valuable in understanding their diagnosis, mechanism and treatment implications. We investigated the manner in which depressive and manic features combine to produce a continuum of mixed states. In 88 subjects with bipolar disorder (DSM-IV), we evaluated symptoms and clinical characteristics, and compared depression-based, mania-based, and other published definitions of mixed states. We developed an index of the extent to which symptoms were mixed (Mixed State Index, MSI) and characterized its relationship to clinical state. Predominately manic and depressive mixed states using criteria from recent literature, as well as Kraepelinian mixed states, had similar symptoms and MSI scores. Anxiety correlated significantly with depression scores in manic subjects and with mania scores in depressed subjects. Discriminant function analysis associated mixed states with symptoms of hyperactivity and negative cognitions, but not subjective depressive or elevated mood. High MSI scores were associated with severe course of illness. For depressive or manic episodes, characteristics of mixed states emerged with two symptoms of the opposite polarity. This was a cross-sectional study. Mixed states appear to be a continuum. An index of the degree to which depressive and manic symptoms combine appears useful in identifying and characterizing mixed states. We propose a depressive or manic episode with three or more symptoms of the opposite polarity as a parsimonious definition of a mixed state.

    Bipolar disorder is a complex psychiatric disorder with high heritability, but its genetic determinants are still largely unknown. Copy number variation (CNV) is one of the sources to explain part of the heritability. However, it is a challenge to estimate discrete values of the copy numbers using continuous signals calling from a set of markers, and to simultaneously perform association testing between CNVs and phenotypic outcomes. The goal of the present study is to perform a series of data filtering and analysis procedures using a DNA pooling strategy to identify potential CNV regions that are related to bipolar disorder. A total of 200 normal controls and 200 clinically diagnosed bipolar patients were recruited in this study, and were randomly divided into eight control and eight case pools. Genome-wide genotyping was employed using Illumina Human Omni1-Quad array with approximately one million markers for CNV calling. We aimed at setting a series of criteria to filter out the signal noise of marker data and to reduce the chance of false-positive findings for CNV regions. We first defined CNV regions for each pool. Potential CNV regions were reported based on the different patterns of CNV status between cases and controls. Genes that were mapped into the potential CNV regions were examined with association testing, Gene Ontology enrichment analysis, and checked with existing literature for their associations with bipolar disorder. We reported several CNV regions that are related to bipolar disorder. Two CNV regions on chromosome 11 and 22 showed significant signal differences between cases and controls (p < 0.05). Another five CNV regions on chromosome 6, 9, and 19 were overlapped with results in previous CNV studies. Experimental validation of two CNV regions lent some support to our reported findings. Further experimental and replication studies could be designed for these selected regions.

The search yielded a total of 434 papers, but only those published in peer-reviewed journals and with samples aged ≥ 18 years were included, resulting in a final sample of 18 papers. Results revealed rather heterogeneous findings concerning the prevalence of bipolar disorders and bipolar spectrum disorders. Lifetime prevalence of bipolar disorder ranged from 0.1 to 7.5%, whereas lifetime prevalence of bipolar spectrum disorders ranged from 2.4 to 15.1%. Differences in the rates of bipolar disorder and bipolar spectrum disorders may be related to the consideration of subthreshold criteria upon diagnosis. Differences in the prevalence of different subtypes of the disorder are discussed in light of diagnostic criteria and instruments applied.

    Topiramate (TPM) is one of the novel antiepileptic drugs and exhibits a wide range of mechanisms of action. Efficacy of TPM has been demonstrated in partial-onset seizures and primary generalized seizures in adults and children, as both monotherapy and adjunctive therapy. More recently, TPM has been proposed as an add-on treatment for patients with lithium-resistant bipolar disorder, especially those displaying rapid-cycling and mixed states. This paper reviews the multiple mechanisms of action and the tolerability profile of TPM in the light of its therapeutic potential in affective disorders. Studies of TPM in bipolar disorder are evaluated, and the efficacy and tolerability issues as a mood stabilizing agent are discussed. PMID:19412496

    Mood is the changing expression of emotion and can be described as a spectrum. The outermost ends of this spectrum highlight two states, the lowest low, melancholia, and the highest high, mania. These mood extremes have been documented repeatedly in human history, being first systematically described by Hippocrates. Nineteenth century contemporaries Falret and Baillarger described two forms of an extreme mood disorder, with the validity and accuracy of both debated. Regardless, the concept of a cycling mood disease was accepted before the end of the 19th century. Kraepelin then described “manic depressive insanity” and presented his description of a full spectrum of mood dysfunction which could be exhibited through single episodes of mania or depression or a complement of many episodes of each. It was this concept which was incorporated into the first DSM and carried out until DSM-III, in which the description of episodic mood dysfunction was used to build a diagnosis of bipolar disorder. Criticism of this approach is explored through discussion of the bipolar spectrum concept and some recent examinations of the clinical validity of these DSM diagnoses are presented.

    Although pharmacotherapy is the mainstay of treatment for bipolar disorder, the combination of evidence-based psychological interventions and drug treatment enhances overall effectiveness, mostly by further protecting patients from relapse/recurrence. In recent years, well-designed controlled studies have added weight to evidence favoring specific psychotherapy modalities for bipolar disorders. However, critical issues that may limit the benefits of psychotherapy in day-to-day clinical practice have emerged. In this article, we critically examine the effectiveness of psychosocial approaches to bipolar illness by reviewing the literature, which has been substantially enriched during the past 5 years. Recent studies further support the fact that psychoeducation and cognitive-behavioral therapy are effective in bipolar disorder, especially the early stages. Family interventions based on a psychoeducational model are also effective. Intensive psychotherapies may be more effective than short, managed care-based ones. Group psychoeducation seems to have long-lasting effects and to be cost-effective. Future studies should focus on neurobiological markers of response to psychotherapy and tailor interventions to specific subtypes.

    An early recognition of bipolar disorders may have an important impact on the prognosis of this disorder according to different mechanisms. Bipolar disorder is nevertheless not easy to detect, the diagnosis being correctly proposed after, in average more than a couple of Years and three different doctors assessments. A short delay before introducing the relevant treatment should help avoiding inappropriate treatments (prescribing, for example, neuroleptics for long periods, antidepressive drugs each time depressive symptoms occurs, absence of treatment despite mood disorders), with their associated negative impact such as mood-switching, rapid cycling or presence of chronic side-effects stigmates. Furthermore, non-treated mood disorders in bipolar disorder are longer, more stigmatizing and may be associated with an increased risk of suicidal behaviour and mortality. Lastly, compliance, an important factor regarding the long term prognosis of bipolar disorder, should be improved when there is a short delay between correct diagnosis and treatment and onset of the disorder. We therefore propose to review the literature for the different pitfalls involved in the diagnosis of bipolar disorder. Non-bipolar mood-disorders are frequently quoted as one of the alternative diagnosis. Hyperthymic temperament, side-effects of prescribed treatments and organic comorbid disorders may be involved. Bipolar disorders have a sex-ratio closer to 1 (men are thus more frequently of the bipolar type in mood-disorders), with earlier age at onset, and more frequent family history of suicidal attempts and bipolar disorder. Schizo-affective disorders are also a major concern regarding the diagnosis of bipolar disorder. This is explained by flat affects sometimes close to anhedonia, presence of a schizoïd personality in bipolar disorder, persecutive hostility that can be considered to be related to irritability rather than a schizophrenic symptom.

    The attention deficit disorder and the bipolar disorder maintain a complex relation. Indeed, these two syndromes share numerous symptoms that engender numerous diagnostic difficulties. According to several studies, it seems that these two disorders are really different with significant differences at the functional and anatomical level. However, there are common cognitive deficits as well as relatively frequent co-morbidity which is necessary to know in order to adjust the treatment.

  4. Factors associated with lithium efficacy in bipolar disorder.

    About one-third of lithium-treated, bipolar patients are excellent lithium responders; that is, lithium monotherapy totally prevents further episodes of bipolar disorder for ten years and more. These patients are clinically characterized by an episodic clinical course with complete remission, a bipolar family history, low psychiatric comorbidity, mania-depression episode sequences, a moderate number of episodes, and a low number of hospitalizations in the pre-lithium period. Recently, it has been found that temperamental features of hypomania (a hyperthymic temperament) and a lack of cognitive disorganization predict the best results of lithium prophylaxis. Lithium exerts a neuroprotective effect, in which increased expression of brain-derived neurotrophic factor (BDNF) and inhibition of the glycogen synthase kinase-3 (GSK-3) play an important role. The response to lithium has been connected with the genotype of the BDNF gene and serum BDNF levels. A better response to lithium is connected with the Met allele of the BDNF Val/Met polymorphism, as is a hyperthymic temperament. Excellent lithium responders have normal cognitive functions and serum BDNF levels, even after long-term duration of the illness. The preservation of cognitive functions in long-term lithium-treated patients may be connected with the stimulation of the BDNF system, with the resulting prevention of affective episodes exerting deleterious cognitive effects, and possibly also with lithium's antiviral effects. A number of candidate genes that are related to neurotransmitters, intracellular signaling, neuroprotection, circadian rhythms, and other pathogenic mechanisms of bipolar disorder were found to be associated with the lithium prophylactic response. The Consortium on Lithium Genetics (ConLiGen) has recently performed the first genome-wide association study on the lithium response in bipolar disorder.

    Complex segregation analyses were conducted on families of bipolar I and bipolar II probands to delineate the mode of inheritance. The probands were ascertained from consecutive referrals to the Mood Disorder Service, University Hospital, University of British Columbia and diagnosed by DSM-III-R and Research Diagnostic Criteria. Data were available on over 1,500 first-degree relatives of the 186 Caucasian probands. The purpose of the analyses was to determine if, after correcting for age and birth cohort, there was evidence for a single major locus. Five models were fit to the data using the statistical package SAGE: (1) dominant, (2) recessive, (3) arbitrary mendelian inheritance, (4) environmental, and (5) no major effects. A single dominant, mendelian major locus was the best fitting of these models for the sample of bipolar I and II probands when only bipolar relatives were defined as affected (polygenic inheritance could not be tested). Adding recurrent major depression to the diagnosis {open_quotes}affected{close_quotes} for relatives reduced the evidence for a major locus effect. Our findings support the undertaking of linkage studies and are consistent with the analyses of the National Institutes of Mental Health (NIMH) Collaborative Study data by Rice et al. and Blangero and Elston. 39 refs., 4 tabs.

    We present a case where dissociative identity disorder was effectively treated with memory retrieval psychotherapy. However, the patient's comorbid bipolar disorder contributed to the patient's instability and fortified the amnesiac barriers that exist between alter personality states in dissociative identity disorder, which made memory retrieval difficult to achieve. Implications from this case indicate that a close collaboration between psychologist and psychiatrist focused on carefully diagnosing and treating existing comorbid conditions may be the most important aspect in treating dissociative identity disorder. We present our experience of successfully treating a patient with dissociative identity disorder and bipolar disorder using this collaborative method.

    An individual can develop bipolar disorder at any age, but emergence during adolescence and young adulthood can lead to a number of problematic behaviors and outcomes. Several drugs are available as first-line treatments, but even optimal pharmacotherapy rarely leads to complete remission and recovery. When added to pharmacologic treatment, certain targeted psychosocial treatments can improve outcomes for young patients with bipolar disorder. Because bipolar disorder affects family members as well as patients, and because adolescents and young adults often live with and are dependent on their parents, the patient's family should usually be included in treatment. Family-focused treatment and dialectical behavior therapy are promising methods of conducting family intervention. With effective treatment and the support of their families, young patients with bipolar disorder can learn to manage their disorder and become independent and healthy adults. PMID:27570931

    Background Studies have shown that chronic inflammation may play a vital role in the pathophysiology of both gastroesophageal reflux disease (GERD) and bipolar disorder. Among patients with GERD, the risk of bipolar disorder has not been well characterized. Objective We explored the relationship between GERD and the subsequent development of bipolar disorder, and examined the risk factors for bipolar disorder in patients with GERD. Methods We identified patients who were diagnosed with GERD in the Taiwan National Health Insurance Research Database. A comparison cohort without GERD was matched according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts based on diagnosis and the prescription of medications. Results The GERD cohort consisted of 21,674 patients, and the comparison cohort consisted of 21,674 matched control patients without GERD. The incidence of bipolar disorder (incidence rate ratio [IRR] 2.29, 95% confidence interval [CI] 1.58–3.36, P<.001) was higher among GERD patients than among comparison cohort. Multivariate, matched regression models showed that the female sex (hazard ratio [HR] 1.78, 95% CI 1.76–2.74, P = .008), being younger than 60 years old (HR 2.35, 95% CI 1.33–4.16, P = .003), and alcohol use disorder (HR 4.89, 95% CI 3.06–7.84, P = .004) were independent risk factors for the development of bipolar disorder among GERD patients. Conclusions GERD may increase the risk of developing bipolar disorder. Based on our data, we suggest that attention should be focused on female patients younger than 60 years, and patients with alcohol use disorder, following a GERD diagnosis. PMID:25255080

    The history of the description by Jean-Pierre Falret of circular insanity, the origin of our present day bipolar disorder, is presented as well as the claims of priority raised by his colleague Jules Baillarger. A detailed account is given of the long-lasting controversy which has often given rise to biased judgments about the respective roles of the two psychiatrists. It is shown that the clinical concept was an expression of Falret's views about the nature of mental disorders and that, through the influence these views had on future nosological systems, the apparently purely picturesque episode corresponds to a landmark in the history of psychiatry.

    Type 2 diabetes mellitus (T2DM) rates are three times higher in patients with bipolar disorder (BD), compared to the general population. This is a major contributing factor to the elevated risk of cardiovascular mortality, the leading cause of death in bipolar patients. There may be shared pathophysiology linking the two disorders, including hypothalamic-pituitary-adrenal and mitochondrial dysfunction, common genetic links, and epigenetic interactions. Life-style, phenomenology of bipolar symptoms, and adverse effects of pharmacotherapy may be contributing factors. Patients with BD and T2DM have a more severe course of illness and are more refractory to treatment. Control of their diabetes is poorer when compared to diabetics without BD, and an existing disparity in medical care may be partly responsible. Glucose abnormalities in bipolar patients need to be screened for and treated. Metformin appears to have the best benefit/risk ratio, and the dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists and analogues also appear promising, although these agents have not been specifically studied in populations with mood disorders. Physicians need to be aware of the increased risk for T2DM and cardiovascular disease in bipolar patients, and appropriate prevention, screening, case finding, and treatment is recommended.

    Bipolar disorder is a chronic, recurrent mental illness characterized by extreme episodes of depressed and manic mood, interspersed with less severe but highly variable mood fluctuations. Here, we develop a novel mathematical approach for exploring the dynamics of bipolar disorder. We investigate how the dynamics of subjective experience of mood in bipolar disorder can be understood using a relaxation oscillator (RO) framework and test the model against mood time-series fluctuations from a set of individuals with bipolar disorder. We show that variable mood fluctuations in individuals diagnosed with bipolar disorder can be driven by the coupled effects of deterministic dynamics (captured by ROs) and noise. Using a statistical likelihood-based approach, we show that, in general, mood dynamics are described by two independent ROs with differing levels of endogenous variability among individuals. We suggest that this sort of nonlinear approach to bipolar disorder has neurobiological, cognitive and clinical implications for understanding this mental illness through a mechacognitive framework.

    Pediatric bipolar disorder is a severe mental illness whose pathophysiology is poorly understood and for which there is an urgent need for improved diagnosis and treatment. MR spectroscopy is a neuroimaging method capable of in vivo measurement of neurochemicals relevant to bipolar disorder neurobiology. MR spectroscopy studies of adult bipolar disorder provide consistent evidence for alterations in the glutamate system and mitochondrial function. In bipolar disorder, these 2 phenomena may be linked because 85% of glucose in the brain is consumed by glutamatergic neurotransmission and the conversion of glutamate to glutamine. The purpose of this article is to review the MR spectroscopic imaging literature in pediatric bipolar disorder, at-risk samples, and severe mood dysregulation, with a focus on the published findings that are relevant to glutamatergic and mitochondrial functioning. Potential directions for future MR spectroscopy studies of the glutamate system and mitochondrial dysfunction in pediatric bipolar disorder are discussed. PMID:24557702

    Background Mitochondria provide most of the energy for brain cells by the process of oxidative phosphorylation. Mitochondrial abnormalities and deficiencies in oxidative phosphorylation have been reported in individuals with schizophrenia (SZ), bipolar disorder (BD), and major depressive disorder (MDD) in transcriptomic, proteomic, and metabolomic studies. Several mutations in mitochondrial DNA (mtDNA) sequence have been reported in SZ and BD patients. Methodology/Principal Findings Dorsolateral prefrontal cortex (DLPFC) from a cohort of 77 SZ, BD, and MDD subjects and age-matched controls (C) was studied for mtDNA sequence variations and heteroplasmy levels using Affymetrix mtDNA resequencing arrays. Heteroplasmy levels by microarray were compared to levels obtained with SNaPshot and allele specific real-time PCR. This study examined the association between brain pH and mtDNA alleles. The microarray resequencing of mtDNA was 100% concordant with conventional sequencing results for 103 mtDNA variants. The rate of synonymous base pair substitutions in the coding regions of the mtDNA genome was 22% higher (p = 0.0017) in DLPFC of individuals with SZ compared to controls. The association of brain pH and super haplogroup (U, K, UK) was significant (p = 0.004) and independent of postmortem interval time. Conclusions Focusing on haplogroup and individual susceptibility factors in psychiatric disorders by considering mtDNA variants may lead to innovative treatments to improve mitochondrial health and brain function.

    Quetiapine (Seroquel), an atypical antipsychotic with established efficacy in the treatment of schizophrenia, shows efficacy in the treatment of acute mania and depression associated with bipolar disorder.Quetiapine, either as monotherapy or in combination with lithium or divalproex sodium (valproate semisodium), is generally well tolerated and effective in reducing manic symptoms in adult and adolescent patients with acute bipolar mania, and is approved for use in adults for this indication. As monotherapy, the drug is also effective in reducing depressive symptoms in patients with bipolar depression. It is associated with a low incidence of extrapyramidal symptom (EPS)-related adverse events and low EPS ratings in bipolar disorder. Quetiapine thus shows potential in the treatment of bipolar depression, and represents a useful agent for the treatment of acute bipolar mania.

    The aim of this study was to assess the performance in emotional processing over time in a sample of euthymic patients with bipolar disorder (BD). Performance in the facial recognition of the six basic emotions (surprise, anger, sadness, happiness, disgust, and fear) did not change during a follow-up period of almost 7 years. These preliminary results suggest that performance in facial emotion recognition might be stable over time in BD. PMID:27416537

    Schizophrenia (SZ) and Bipolar Disorder (BD) are highly inheritable chronic mental disorders with a worldwide prevalence of around 1%. Despite that many efforts had been made to characterize biomarkers in order to allow for biological testing for their diagnoses, these disorders are currently detected and classified only by clinical appraisal based on the Diagnostic and Statistical Manual of Mental Disorders. Olfactory neuroepithelium-derived neuronal precursors have been recently proposed as a model for biomarker characterization. Because of their peripheral localization, they are amenable to collection and suitable for being cultured and propagated in vitro. Olfactory neuroepithelial cells can be obtained by a non-invasive brush-exfoliation technique from neuropsychiatric patients and healthy subjects. Neuronal precursors isolated from these samples undergo in vitro the cytoskeletal reorganization inherent to the neurodevelopment process which has been described as one important feature in the etiology of both diseases. In this paper, we will review the current knowledge on microtubular organization in olfactory neurons of patients with SZ and with BD that may constitute specific cytoskeletal endophenotypes and their relation with alterations in L-type voltage-activated Ca(2+) currents. Finally, the potential usefulness of neuronal precursors for pharmacological screening will be discussed.

    Although pharmacotherapy is the mainstay of treatment for bipolar disorder, medication offers only partial relief for patients. Treatment with pharmacologic interventions alone is associated with disappointingly low rates of remission, high rates of recurrence, residual symptoms, and psychosocial impairment. Bipolar-specific therapy is increasingly recommended as an essential component of illness management. This review summarizes the available data on psychotherapy for adults with bipolar disorder. We conducted a search of the literature for outcome studies published between 1995 and 2013 and identified 35 reports of 28 randomized controlled trials testing individual or group psychosocial interventions for adults with bipolar disorder. These reports include systematic trials investigating the efficacy and effectiveness of individual psychoeducation, group psychoeducation, individual cognitive-behavioral therapy, group cognitive-behavioral therapy, family therapy, interpersonal and social rhythm therapy, and integrated care management. The evidence demonstrates that bipolar disorder-specific psychotherapies, when added to medication for the treatment of bipolar disorder, consistently show advantages over medication alone on measures of symptom burden and risk of relapse. Whether delivered in a group or individual format, those who receive bipolar disorder-specific psychotherapy fare better than those who do not. Psychotherapeutic strategies common to most bipolar disorder-specific interventions are identified. PMID:26279641

    This study aimed to identify neuroimaging measures associated with risk for, or protection against, bipolar disorder by comparing youth offspring of parents with bipolar disorder versus youth offspring of non-bipolar parents versus offspring of healthy parents in (i) the magnitude of activation within emotional face processing circuitry; and (ii) functional connectivity between this circuitry and frontal emotion regulation regions. The study was conducted at the University of Pittsburgh Medical Centre. Participants included 29 offspring of parents with bipolar disorder (mean age = 13.8 years; 14 females), 29 offspring of non-bipolar parents (mean age = 13.8 years; 12 females) and 23 healthy controls (mean age = 13.7 years; 11 females). Participants were scanned during implicit processing of emerging happy, sad, fearful and angry faces and shapes. The activation analyses revealed greater right amygdala activation to emotional faces versus shapes in offspring of parents with bipolar disorder and offspring of non-bipolar parents than healthy controls. Given that abnormally increased amygdala activation during emotion processing characterized offspring of both patient groups, and that abnormally increased amygdala activation has often been reported in individuals with already developed bipolar disorder and those with major depressive disorder, these neuroimaging findings may represent markers of increased risk for affective disorders in general. The analysis of psychophysiological interaction revealed that offspring of parents with bipolar disorder showed significantly more negative right amygdala-anterior cingulate cortex functional connectivity to emotional faces versus shapes, but significantly more positive right amygdala-left ventrolateral prefrontal cortex functional connectivity to happy faces (all P-values corrected for multiple tests) than offspring of non-bipolar parents and healthy controls.

    Timothy Syndrome (TS) is caused by very rare exonic mutations of the CACNA1C gene that produce delayed inactivation of Cav1.2 voltage-gated calcium channels during cellular action potentials, with greatly increased influx of calcium into the activated cells. The major clinical feature of this syndrome is a long QT interval that results in cardiac arrhythmias. However, TS also includes cognitive impairment, autism and major developmental delays in many of the patients. We observed the appearance of bipolar disorder (BD) in a patient with a previously reported case of TS, who is one of the very few patients to survive childhood. This is most interesting because the common single-nucleotide polymorphism (SNP) most highly associated with BD is rs1006737, which we show here is a cis-expression quantitative trait locus for CACNA1C in human cerebellum, and the risk allele (A) is associated with decreased expression. To combine the CACNA1C perturbations in the presence of BD in this patient and in patients with the common CACNA1C SNP risk allele, we would propose that either increase or decrease in calcium influx in excitable cells can be associated with BD. In treatment of BD with calcium channel blocking drugs, we would predict better response in patients without the risk allele, because they have increased CACNA1C expression.

    The categorical diagnostic model of bipolar disorders (DSM IV) has brought about increasing questioning, since its use gains troubles related not only to clinical experience, but to epidemiological studies as well. Regarding this, other models have emerged, such as the bipolar spectrum by Akiskal that covers the classic bipolar disorder on one side to unipolar disorder on the other, including soft bipolar disorders as well. The authors start from this notion of bipolar spectrum to set out the relationship between bipolar disease and psychoanalytical concepts of depression and mania. They develop Freud's basic theories and those of the British School that constitute a strong and coherent theoretical structure. Psychoanalysis proposes a unitary psychopathological model that manifests itself as depression or maniac reaction as secondary defense, to account for both the clinical expression and the psychodynamic comprehension of mood disorders.

    Recent studies have questioned current diagnostic systems that split mood disorders into the independent categories of bipolar disorders and depressive disorders. The current classification of mood disorders runs against Kraepelin's unitary view of manic-depressive insanity (illness). The main findings of recent studies supporting a continuity between bipolar disorders (mainly bipolar II disorder) and major depressive disorder are presented. The features supporting a continuity between bipolar II disorder and major depressive disorder currently are 1) depressive mixed states (mixed depression) and dysphoric (mixed) hypomania (opposite polarity symptoms in the same episode do not support a splitting of mood disorders); 2) family history (major depressive disorder is the most common mood disorder in relatives of bipolar probands); 3) lack of points of rarity between the depressive syndromes of bipolar II disorder and major depressive disorder; 4) major depressive disorder with bipolar features such as depressive mixed states, young onset age, atypical features, bipolar family history, irritability, racing thoughts, and psychomotor agitation; 5) a high proportion of major depressive disorders shifting to bipolar disorders during long-term follow-up; 6) a high proportion of major depressive disorders with history of manic and hypomanic symptoms; 7) factors of hypomania present in major depressive disorder episodes; 8) recurrent course of major depressive disorder; and 9) depressive symptoms much more common than manic and hypomanic symptoms in the course of bipolar disorders.

    2011-12-01

    The longitudinal course of bipolar disorder (BD) is highly impairing. This article reviews recent research on functional impairment in the course of BD, the roles of social and intrafamilial stress in relapse and recovery, and the role of adjunctive psychosocial interventions in reducing risk and enhancing functioning. Comparative findings in adult and childhood BD are highlighted. Life events and family-expressed emotion have emerged as significant predictors of the course of BD. Studies of social information processing suggest that impairments in the recognition of facial emotions may characterize both adult- and early-onset bipolar patients. Newly developed psychosocial interventions, particularly those that focus on family and social relationships, are associated with more rapid recovery from episodes and better psychosocial functioning. Family-based psychoeducational approaches are promising as early interventions for children with BD or children at risk of developing the disorder. For adults, interpersonal therapy, mindfulness-based strategies, and cognitive remediation may offer promise in enhancing functioning.

    The high heterogeneity of response to antidepressant treatment in major depressive disorder (MDD) makes individual treatment outcomes currently unpredictable. It has been suggested that resistance to antidepressant treatment might be due to undiagnosed bipolar disorder or bipolar spectrum features. Here, we investigate the relationship between genetic susceptibility for bipolar disorder and response to treatment with antidepressants in MDD. Polygenic scores indexing risk for bipolar disorder were derived from the Psychiatric Genomics Consortium Bipolar Disorder whole genome association study. Linear regressions tested the effect of polygenic risk scores for bipolar disorder on proportional reduction in depression severity in two large samples of individuals with MDD, treated with antidepressants, NEWMEDS (n=1,791) and STAR*D (n=1,107). There was no significant association between polygenic scores for bipolar disorder and response to treatment with antidepressants. Our data indicate that molecular measure of genetic susceptibility to bipolar disorder does not aid in understanding non-response to antidepressants.

    The transcription factor 4 (TCF4) gene encodes a helix-loop-helix transcription factor protein, which initiates neuronal differentiation and is primarily expressed during nervous system development. The aim of the present study is to investigate the association of the TCF4 rs9960767 polymorphism and bipolar disorder, which is highly heritable. DNA isolation was performed on 95 patients with bipolar disorder and 108 healthy control subjects to examine the TCF4 rs9960767 polymorphism. Genotypic and allelic frequencies were determined using the polymerase chain reaction-restriction fragment length polymorphism method designed in our laboratory. Statistical analysis was performed using χ2 test within the 95% confidence interval. Odds ratios were calculated and Hardy-Weinberg equilibrium (HWE) was verified for all control subjects and patients. The A allele frequency was 95.8% in the patients and 94.4% in the control subjects, and 4.2% in the patients and 5.6% in the control subjects for the C allele. The genotype frequencies of the TCF4 gene rs9960767 variant were as follows: AA, 91.6% and AC, 8.4% in patients with bipolar (CC genotype was not observed in cases); AA, 89.8%; AC, 9.3% and CC, 0.9% in the control subjects. No statistically significant difference was identified between the patients and control subjects (χ2=0.937; P=0.626). In addition, gender specific analysis was performed, although no significant association was found according to the gender distrubition. All patients and control subjects were in HWE (P>0.05). Statistical analysis of the data indicates that the TCF4 gene rs9960767 polymorphism is not an independent risk factor for bipolar disorder in the overall population or in terms of gender; however, an increased population size would improve the statistical power.

    The transcription factor 4 (TCF4) gene encodes a helix-loop-helix transcription factor protein, which initiates neuronal differentiation and is primarily expressed during nervous system development. The aim of the present study is to investigate the association of the TCF4 rs9960767 polymorphism and bipolar disorder, which is highly heritable. DNA isolation was performed on 95 patients with bipolar disorder and 108 healthy control subjects to examine the TCF4 rs9960767 polymorphism. Genotypic and allelic frequencies were determined using the polymerase chain reaction-restriction fragment length polymorphism method designed in our laboratory. Statistical analysis was performed using χ2 test within the 95% confidence interval. Odds ratios were calculated and Hardy-Weinberg equilibrium (HWE) was verified for all control subjects and patients. The A allele frequency was 95.8% in the patients and 94.4% in the control subjects, and 4.2% in the patients and 5.6% in the control subjects for the C allele. The genotype frequencies of the TCF4 gene rs9960767 variant were as follows: AA, 91.6% and AC, 8.4% in patients with bipolar (CC genotype was not observed in cases); AA, 89.8%; AC, 9.3% and CC, 0.9% in the control subjects. No statistically significant difference was identified between the patients and control subjects (χ2=0.937; P=0.626). In addition, gender specific analysis was performed, although no significant association was found according to the gender distrubition. All patients and control subjects were in HWE (P>0.05). Statistical analysis of the data indicates that the TCF4 gene rs9960767 polymorphism is not an independent risk factor for bipolar disorder in the overall population or in terms of gender; however, an increased population size would improve the statistical power. Furthermore, additional gene variants that are specifically involved in neuronal development may be analyzed for revealing the complex genetic architecture of bipolar disorder. An

    Calcium signaling is important for synaptic plasticity, generation of brain rhythms, regulating neuronal excitability, data processing and cognition. Impairment in calcium homeostasis contributed to the development of psychiatric disorders such as bipolar disorder (BP). MCU is the most important calcium transporter in mitochondria inner membrane responsible for influx of Ca[Formula: see text]. MICU1 is linked with MCU and has two canonical EF hands that are vital for its activity and regulates MCU-mediated Ca[Formula: see text] influx. In the current study, we aimed to investigate the role of genetic alteration of EF hand calcium binding motifs of MICU1 on the development of BP. We examined patients with BP, first degree relatives of these patients and healthy volunteers for mutations and polymorphisms in EF hand calcium binding motifs of MICU1. The result showed no SNP/mutation in BP patients, in healthy subjects and in first degree relatives. Additionally, alignment of the EF hand calcium binding regions among species (Gallus-gallus, Canis-lupus-familiaris, Bos-taurus, Mus-musculus, Rattus-norvegicus, Pan-troglodytes, Homosapiens and Danio-rerio) showed exactly the same amino acids (DLNGDGEVDMEE and DCDGNGELSNKE) except in one of the calcium binding domain of Danio-rerio that there was only one difference; leucine instead of Methionine. Our results showed that the SNP on EF-hand Ca[Formula: see text] binding domains of MICU1 gene had no effect in phenotypic characters of BP patients. PMID:27297032

  11. The Treatment of Adult Bipolar Disorder with Aripiprazole: A Systematic Review

    PubMed Central

    2016-01-01

    Bipolar disorder is characterized by exacerbations of opposite mood polarity, ranging from manic to major depressive episodes. In the current nosological system of the Diagnostic and Statistical Manual – 5th edition (DSM-5), it is conceptualized as a spectrum disorder consisting of bipolar disorder type I, bipolar disorder type II, cyclothymic disorder, and bipolar disorder not otherwise specified. Treatment of all phases of this disorder is primarily with mood stabilizers, but many patients either show resistance to the conventional mood stabilizing medications or are intolerant to their side-effects. In this setting, second-generation antipsychotics have gained prominence as many bipolar subjects who are otherwise treatment refractory show response to these agents. Aripiprazole is a novel antipsychotic initially approved for the treatment of schizophrenia but soon found to be effective in bipolar disorder. This drug is well studied, as randomized controlled trials have been conducted in various phases of bipolar disorders. Aripiprazole exhibits the pharmacodynamic properties of partial agonism, functional selectivity, and serotonin-dopamine activity modulation – the new exemplars in the treatment of major psychiatric disorders. It is the first among a new series of psychotropic medications, which now also include brexpiprazole and cariprazine. The current review summarizes the data from controlled trials regarding the efficacy and safety of aripiprazole in adult bipolar patients. On the basis of this evidence, aripiprazole is found to be efficacious in the treatment and prophylaxis of manic and mixed episodes but has no effectiveness in acute and recurrent bipolar depression.

    Background Relapse prevention in bipolar disorder can be improved by monitoring symptoms in patients' daily life. Smartphone apps are easy-to-use, low-cost tools that can be used to assess this information. To date, few studies have examined the usefulness of smartphone data for monitoring symptoms in bipolar disorder. Objective We present results from a pilot test of a smartphone-based monitoring system, Social Information Monitoring for Patients with Bipolar Affective Disorder (SIMBA), that tracked daily mood, physical activity, and social communication in 13 patients. The objective of this study was to investigate whether smartphone measurements predicted clinical symptoms levels and clinical symptom change. The hypotheses that smartphone measurements are (1) negatively related to clinical depressive symptoms and (2) positively related to clinical manic symptoms were tested. Methods Clinical rating scales were administered to assess clinical depressive and manic symptoms. Patients used a smartphone with the monitoring app for up to 12 months. Random-coefficient multilevel models were computed to analyze the relationship between smartphone data and externally rated manic and depressive symptoms. Overall clinical symptom levels and clinical symptom changes were predicted by separating between-patient and within-patient effects. Using established clinical thresholds from the literature, marginal effect plots displayed clinical relevance of smartphone data. Results Overall symptom levels and change in clinical symptoms were related to smartphone measures. Higher overall levels of clinical depressive symptoms were predicted by lower self-reported mood measured by the smartphone (beta=-.56, P<.001). An increase in clinical depressive symptoms was predicted by a decline in social communication (ie, outgoing text messages: beta=-.28, P<.001) and a decline in physical activity as measured by the smartphone (ie, cell tower movements: beta=-.11, P=.03).

    We tested whether the human period 2 gene (hper2), one of the essential components of the circadian oscillator, might have influence on bipolar disorder. We screened 88 bipolar disorder patients and 127 controls, all of Japanese origin. Screening in the casein kinase I epsilon (CKIepsilon) binding region of hper2, which was previously reported in familial advanced sleep-phase syndrome patients, with polymerase chain reaction amplification revealed four polymorphisms. One of the four polymorphisms had an amino acid substitution of a serine at 662 with a glycine (S662G). The frequencies of the S662G allele and genotypes on patients with bipolar disorder were very low and had no difference from those in controls. Polymorphism on the CKIepsilon binding region of hper2 gene which was previously reported, is unlikely to play an important role in the development of bipolar disorder. PMID:12565145

    Patients with subthreshold hypomania (SBP; subthreshold bipolar disorder) were indistinguishable from those with bipolar disorder (BP)-II on clinical bipolar validators, but their analyses lacked biological and pharmacological treatment data. Because inflammation and neuroprogression underlies BP, we hypothesized that cytokines and brain-derived neurotrophic factor (BDNF) are biomarkers for BP. We enrolled 41 drug-naïve patients with SBP and 48 with BP-II undergoing 12 weeks of pharmacological treatment (valproic acid, fluoxetine, risperidone, lorazepam). The Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) were used to evaluate clinical responses at baseline and at weeks 0, 1, 2, 4, 8, and 12. Inflammatory cytokines (tumour necrosis factor [TNF]-α, transforming growth factor [TGF]-β1, interleukin [IL]-6, IL-8 and IL-1β) and BDNF levels were also measured. Mixed models repeated measurement was used to examine the therapeutic effect and changes in BDNF and cytokine levels between the groups. HDRS and YMRS scores significantly (P < 0.001) declined in both groups, the SBP group had significantly lower levels of BDNF (P = 0.005) and TGF-β1 (P = 0.02). Patients with SBP and BP-II respond similarly to treatment, but SBP patients may have different neuroinflammation marker expression. PMID:27270858

    Changes in speech have been suggested as sensitive and valid measures of depression and mania in bipolar disorder. The present study aimed at investigating (1) voice features collected during phone calls as objective markers of affective states in bipolar disorder and (2) if combining voice features with automatically generated objective smartphone data on behavioral activities (for example, number of text messages and phone calls per day) and electronic self-monitored data (mood) on illness activity would increase the accuracy as a marker of affective states. Using smartphones, voice features, automatically generated objective smartphone data on behavioral activities and electronic self-monitored data were collected from 28 outpatients with bipolar disorder in naturalistic settings on a daily basis during a period of 12 weeks. Depressive and manic symptoms were assessed using the Hamilton Depression Rating Scale 17-item and the Young Mania Rating Scale, respectively, by a researcher blinded to smartphone data. Data were analyzed using random forest algorithms. Affective states were classified using voice features extracted during everyday life phone calls. Voice features were found to be more accurate, sensitive and specific in the classification of manic or mixed states with an area under the curve (AUC)=0.89 compared with an AUC=0.78 for the classification of depressive states. Combining voice features with automatically generated objective smartphone data on behavioral activities and electronic self-monitored data increased the accuracy, sensitivity and specificity of classification of affective states slightly. Voice features collected in naturalistic settings using smartphones may be used as objective state markers in patients with bipolar disorder. PMID:27434490

    Bipolar affective disorder is a debilitating illness that manifests as cyclical episodes of mood elevation and depression, but the treatment of the depressive episodes (i.e., bipolar depression) differs considerably from the treatment of major depressive disorder. In bipolar affective disorder, it is well known that patients spend a significantly greater amount of time in depressive episodes than manic or hypomanic episodes, yet there are currently just three Food and Drug Administration-approved agents for the treatment of bipolar depression: (1) olanzapine/fluoxetine combination (2) quetiapine, both immediate- and extended-release, and (3) lurasidone. The literature review presented here focuses on the clinical trials that led to the Food and Drug Administration-approval of these second generation antipsychotics in the treatment of bipolar depression. The discussion highlights key considerations regarding overall treatment strategies to aid clinicians in the selection of pharmacologic agents. Recommended monitoring parameters, potential adverse effects, and pertinent counseling points for second generation antipsychotics used in bipolar depression are included. PMID:27079776

    We are currently surveying the genome with polymorphic DNA markers in search of loci linked to bipolar disorder (manic-depressive illness) in three populations: 20 families (175 subjects) from the general North American population from San Diego (UCSD) and Vancouver (UBC); 3 Icelandic families (55 subjects); and an Old Order Amish pedigree 110 (118 subjects). Over 50 markers on chromosomes 1, 2, 5, 11, 17, 18, 20 and 21 have been examined. All markers have been tested in the Amish and Icelandic families, and a portion of them in the UCSD/UBC families, which we have only recently begun genotyping. The following candidate genes have been examined: {beta}-TSH, dopamine transporter (HDAT), {beta}2 adrenergic receptor (ADRB2), glucocorticoid type II receptor (GRL), D2 dopamine receptor, serotonin transporter (HSERT), and G{alpha}s G protein subunit (GNAS1). Linkage analysis was conducted using an autosomal dominant model with age-dependent reduced penetrance. Subjects with bipolar, schizoaffective, or recurrent major depressive disorders were considered affected. No significant evidence for linkage was obtained. Mildly positive lods ranging between 1.1 and 1.6 were obtained for three loci: D11S29, HDAT, and GRL.

    According to cognitive theory, negative self-schemas are involved in the occurrence of depression. Whereas implicit depressive self-associations have been found in unipolar depression, it is unknown whether impaired associations with regard to the self are also involved in Bipolar Disorder (BD). This study investigated whether a bias in self-associations is a characteristic of bipolar disorder and whether discrepancies between implicit and explicit self-evaluations may be relevant for understanding bipolar psychopathology. Implicit and explicit self-associations were assessed in patients with BD (n=99), in patients with depressive disorder (n=1236), and healthy controls (n=387). Analyses of variance and correlation analyses were used to compare bipolar patients to controls and unipolar patients on implicit self-associations and the discrepancy between implicit and explicit self-associations. Similar to unipolar patients, patients with BD showed stronger implicit depressive self-associations than controls. Specifically for bipolar patients there was no significant correlation between implicit and explicit depressive self-associations. In a similar vein, discrepancies between implicit and explicit self-associations were relatively pronounced in symptomatic bipolar patients as compared to both healthy controls and unipolar depressed patients. Thus automatic depressive self-associations were characteristic for all mood disorders whereas a lack of concordance between implicit and explicit self-associations was specific for BD.

    Neurologists are increasingly faced with the daunting task of disentangling dementia from primary psychiatric conditions or recognizing their coexistence in older patients. Both schizophrenia and bipolar disorder are characterized by substantial intergroup cognitive heterogeneity among older and younger patients. In schizophrenia, deficits in many cognitive domains are common; however, "rapid forgetting," loss of crystallized knowledge, and greater than age-normal declines in cognitive function are rare and warrant careful evaluation for secondary causes. The cognitive deficits associated with bipolar disorder tend be most severe during acute affective episodes, but some deficits tend to persist even during periods of relative euthymia. Lifetime number of affective episodes in bipolar disorder may adversely affect cognitive functions in bipolar disorder, but severe deficits and/or substantive declines over a period of a few years are unusual and warrant careful evaluation for secondary causes.

    The course of bipolar disorder in children and adolescents is highly recurrent and impairing. This article describes the adaptation of family-focused treatment (FFT) for children and adolescents with bipolar disorder. FFT is given in 21 sessions over 9 months, and is usually initiated during the recovery period following an acute episode of depression or (hypo)mania. The treatment consists of an engagement phase followed by psychoeducation, communication enhancement training, and problem-solving skills training. Results of randomized trials in adults and adolescents find that patients with bipolar disorder who receive FFT and pharmacotherapy recover from episodes more quickly and have longer periods of sustained remission than patients who receive briefer forms of therapy and pharmacotherapy. The application of FFT to youth who are genetically at risk for bipolar disorder is described. Problems in disseminating empirically supported family interventions in community settings are discussed. PMID:22801288

This is the first report of the International Society for Bipolar Disorder (ISBD) Task Force on Older-Age Bipolar Disorder (OABD). Methods This task force report addresses the unique aspects of OABD including epidemiology and clinical features, neuropathology and biomarkers, physical health, cognition, and care approaches. Results The report describes an expert consensus summary on OABD that is intended to advance the care of patients, and shed light on issues of relevance to BD research across the lifespan. Although there is still a dearth of research and health efforts focused on older adults with BD, emerging data has brought some answers, innovative questions, and novel perspectives related to the notion of late onset, medical comorbidity, and the vexing issue of cognitive impairment and decline. Conclusions Improving our understanding of the biological, clinical, and social underpinnings relevant to OABD is an indispensable step in building a complete map of BD across the lifespan.

    Bipolar disorder and alcohol use disorder (AUD) have a high rate of comorbidity, more than 50% of individuals with bipolar disorder also receive a diagnosis of AUD in their lifetimes. Although both disorders are heritable, it is unclear if the same genetic factors mediate risk for bipolar disorder and AUD. We examined 733 Costa Rican individuals from 61 bipolar pedigrees. Based on a best-estimate process, 32% of the sample met criteria for bipolar disorder, 17% had a lifetime AUD diagnosis, 32% met criteria for lifetime nicotine dependence, and 21% had an anxiety disorder. AUD, nicotine dependence and anxiety disorders were relatively more common among individuals with bipolar disorder than in their non-bipolar relatives. All illnesses were shown to be heritable and bipolar disorder was genetically correlated with AUD, nicotine dependence and anxiety disorders. The genetic correlation between bipolar and AUD remained when controlling for anxiety, suggesting that unique genetic factors influence risk for comorbid bipolar and AUD independent of anxiety. Our findings provide evidence for shared genetic effects on bipolar disorder and AUD risk. Demonstrating that common genetic factors influence these independent diagnostic constructs could help to refine our diagnostic nosology. PMID:24321773

  10. Response to lithium in bipolar disorder: clinical and genetic findings.

    PubMed

    Rybakowski, Janusz K

    2014-06-18

    The use of lithium is a cornerstone for preventing recurrences in bipolar disorder (BD). The response of patients with bipolar disorder to lithium has different levels of magnitude. About one-third of lithium-treated patients are excellent lithium responders (ELR), showing total prevention of the episodes. A number of clinical characteristics were delineated in patients with favorable response to lithium as regards to clinical course, family history of mood disorders, and psychiatric comorbidity. We have also demonstrated that temperamental features of hypomania (a hyperthymic temperament) and a lack of cognitive disorganization predict the best results of lithium prophylaxis. A degree of prevention against manic and depressive episodes has been regarded as an endophenotype for pharmacogenetic studies. The majority of data have been gathered from so-called "candidate" gene studies. The candidates were selected on the basis of neurobiology of bipolar disorder and mechanisms of lithium action including, among others, neurotransmission, intracellular signaling, neuroprotection or circadian rhythms. We demonstrated that response to lithium has been connected with the genotype of BDNF gene and serum BDNF levels and have shown that ELR have normal cognitive functions and serum BDNF levels, even after long-term duration of the illness. A number of genome-wide association studies (GWAS) of BD have been also performed in recent years, some of which also focused on lithium response. The Consortium on Lithium Genetics (ConLiGen) has established the large sample for performing the genome-wide association study (GWAS) of lithium response in BD, and the first results have already been published.

    Objective: Oxidative stress and mitochondrial dysfunction are 2 closely integrated processes implicated in the physiopathology of bipolar disorder. Advanced proton magnetic resonance spectroscopy techniques enable the measurement of levels of lactate, the main marker of mitochondrial dysfunction, and glutathione, the predominant brain antioxidant. The objective of this study was to measure brain lactate and glutathione levels in bipolar disorder and healthy controls. Methods: Eighty-eight individuals (50 bipolar disorder and 38 healthy controls) underwent 3T proton magnetic resonance spectroscopy in the dorsal anterior cingulate cortex (2x2x4.5cm3) using a 2-D JPRESS sequence. Lactate and glutathione were quantified using the ProFit software program. Results: Bipolar disorder patients had higher dorsal anterior cingulate cortex lactate levels compared with controls. Glutathione levels did not differ between euthymic bipolar disorder and controls. There was a positive correlation between lactate and glutathione levels specific to bipolar disorder. No influence of medications on metabolites was observed. Conclusion: This is the most extensive magnetic resonance spectroscopy study of lactate and glutathione in bipolar disorder to date, and results indicated that euthymic bipolar disorder patients had higher levels of lactate, which might be an indication of altered mitochondrial function. Moreover, lactate levels correlated with glutathione levels, indicating a compensatory mechanism regardless of bipolar disorder diagnosis. PMID:27207914

    Shinozaki, Gen; Potash, James B

    2014-11-01

    The last several years have been breakthrough ones in bipolar disorder (BPD) genetics, as the field has identified robust risk variants for the first time. Leading the way have been genome-wide association studies (GWAS) that have assessed common genetic markers across very large groups of patients and controls. These have resulted in findings in genes including ANK3, CACNA1C, SYNE1, ODZ4, and TRANK1. Additional studies have begun to examine the biology of these genes and how risk variants influence aspects of brain and behavior that underlie BPD. For example, carriers of the CACNA1C risk variant have been found to exhibit hippocampal and anterior cingulate dysfunction during episodic memory recall. This work has shed additional light on the relationship of bipolar susceptibility variants to other disorders, particularly schizophrenia. Even larger BPD GWAS are expected with samples now amassed of 21,035 cases and 28,758 controls. Studies have examined the pharmacogenomics of BPD with studies of lithium response, yielding high profile results that remain to be confirmed. The next frontier in the field is the identification of rare bipolar susceptibility variants through large-scale DNA sequencing. While only a couple of papers have been published to date, many studies are underway. The Bipolar Sequencing Consortium has been formed to bring together all of the groups working in this area, and to perform meta-analyses of the data generated. The consortium, with 13 member groups, now has exome data on ~3,500 cases and ~5,000 controls, and on ~162 families. The focus will likely shift within several years from exome data to whole genome data as costs of obtaining such data continue to drop. Gene-mapping studies are now providing clear results that provide insights into the pathophysiology of the disorder. Sequencing studies should extend this process further. Findings could eventually set the stage for rational therapeutic development. PMID:25194313

  13. Pediatric Bipolar Disorder: Combination Pharmacotherapy, Adverse Effects, and Treatment of High-Risk Youth.

    Treating bipolar disorder in pediatric patients is challenging because data from rigorous trials of pharmacotherapy in this population are still not plentiful enough. Furthermore, the treatment of children and adolescents is complicated by the frequent need to combine pharmacotherapies to address all bipolar symptoms as well as this population's elevated risk for experiencing side effects. Additionally, young patients with depressive episodes who are at high risk for developing bipolar disorder need careful treatment to prevent or delay the emergence of mania. Despite these challenges, clinicians should evaluate the existing pediatric literature, extrapolate evidence obtained from adult patients, and draw from clinical experience to guide treatment decisions for children and adolescents with bipolar disorder.

    Background The epidemiology of rapid-cycling bipolar disorder in the community is largely unknown. Aims To investigate the epidemiological characteristics of rapid-cycling and non-rapid-cycling bipolar disorder in a large cross-national community sample. Method The Composite International Diagnostic Interview (CIDI version 3.0) was used to examine the prevalence, severity, comorbidity, impairment, suicidality, sociodemographics, childhood adversity and treatment of rapid-cycling and non-rapid-cycling bipolar disorder in ten countries (n = 54 257). Results The 12-month prevalence of rapid-cycling bipolar disorder was 0.3%. Roughly a third and two-fifths of participants with lifetime and 12-month bipolar disorder respectively met criteria for rapid cycling. Compared with the non-rapid-cycling, rapid-cycling bipolar disorder was associated with younger age at onset, higher persistence, more severe depressive symptoms, greater impairment from depressive symptoms, more out-of-role days from mania/hypomania, more anxiety disorders and an increased likelihood of using health services. Associations regarding childhood, family and other sociodemographic correlates were less clear cut. Conclusions The community epidemiological profile of rapid-cycling bipolar disorder confirms most but not all current clinically based knowledge about the illness. PMID:20194545

    Pediatric bipolar disorder is a severe and impairing illness. Characterizing the impact of pediatric bipolar disorder on cognitive function might aid in understanding the phenomenology of the disorder. While previous studies of pediatric bipolar disorder have reported deficits in cognitive control and reward behavior, little is understood about how affective processes influence behavioral control. Relative to prior studies using manual-response paradigms, eye movement tasks provide a more precise assessment of reward sensitivity and cognitive and motor control. The current study compares 20 youths with bipolar disorder (mean age = 13.9 years ± 2.22) and 23 healthy subjects (mean age = 13.8 years ± 2.49) on a mixed pro-antisaccade task with monetary incentives. On both types of saccades, participants were presented with three types of incentives: those where subjects can win money, lose money, or neither win nor lose money. Impaired reward processing was found in youths with bipolar disorder relative to controls, particularly on antisaccades. This difference was reflected in lower error rates during incentive trials in the control but not in the bipolar disorder group. By comparison, no group differences were found on prosaccade trials. The results provide further evidence for deficits in cognitive and reward processing in bipolar disorder. PMID:20080923

    The objective of the present study was to compare two components of executive functioning, response monitoring and inhibition in bipolar disorder (BP) and schizophrenia (SZ). The saccadic countermanding task is a translational paradigm optimized for detecting subtle abnormalities in response monitoring and response inhibition. We have previously reported countermanding performance abnormalities in SZ, but the degree to which these impairments are shared by other psychotic disorders is unknown. 18 BP, 17 SZ, and 16 demographically-matched healthy controls (HC) participated in a saccadic countermanding task. Performance on the countermanding task is approximated as a race between movement generation and inhibition processes; this model provides an estimate of the time needed to cancel a planned movement. Response monitoring was assessed by the reaction time (RT) adjustments based on trial history. Like SZ patients, BP patients needed more time to cancel a planned movement. The two patient groups had equivalent inhibition efficiency. On trial history-based RT adjustments, however, we found a trend towards exaggerated trial history-based slowing in SZ compared to BP. Findings have implications for understanding the neurobiology of cognitive control, for defining the etiological overlap between schizophrenia and bipolar disorder and for developing pharmacological treatments of cognitive impairments.

    Cognitive variables contribute to the etiology of affective disorders. With the differentiation between explicit and implicit measures some studies have indicated underlying depressogenic schemata even in bipolar disorders. We tested for differences in implicit motives and cognitive variables between patients with remitted unipolar and bipolar disorder compared to controls and in a high-risk sample. Additionally we investigated whether affective symptoms relate to those variables. We cross-sectionally examined N=164 participants (53 with bipolar disorder, 58 with major depression, and 53 without affective disorders) and a high-risk sample (N=49) of adolescent children of either parents with unipolar or bipolar disorder or of healthy parents. The Multi-Motive-Grid was used to measure the implicit motives achievement, affiliation, and power, in addition to the cognitive measures of self-esteem, dysfunctional attitudes, and perfectionism. Unipolar and bipolar groups did not differ from healthy controls in implicit motives but showed higher scores in the cognitive factors. Adolescents at high risk for unipolar disorder showed lower scores in the power and achievement motives compared to adolescents at low risk. Subsyndromal depressive symptoms were related to the cognitive variables in both samples. Our results underline the importance of cognitive-behavioral treatment for both unipolar and bipolar disorder. PMID:24182545

    Bipolar disorder (BD) is a major medical and social burden, whose cause, pathophysiology and treatment are not agreed on. It is characterized by recurrent periods of mania and depression (Bipolar I) or of hypomania and depression (Bipolar II). Its inheritance is polygenic, with evidence of a neurotransmission imbalance and disease progression. Patients often take multiple agents concurrently, with incomplete therapeutic success, particularly with regard to depression. Suicide is common. Of the hypotheses regarding the action of mood stabilizers in BD, the “arachidonic acid (AA) cascade” hypothesis is presented in detail in this review. It is based on evidence that chronic administration of lithium, carbamazepine, sodium valproate, or lamotrigine to rats downregulated AA turnover in brain phospholipids, formation of prostaglandin E2, and/or expression of AA-cascade enzymes, including cytosolic phospholipase A2, cyclooxygenase-2 and/or acyl-CoA synthetase. The changes were selective for AA, since brain docosahexaenoic or palmitic acid metabolism, when measured, was unaffected, and topiramate, ineffective in BD, did not modify the rat brain AA cascade. Downregulation of the cascade by the mood stabilizers corresponded to inhibition of AA neurotransmission via dopaminergic D2-like and glutamatergic NMDA receptors. Unlike the mood stabilizers, antidepressants that increase switching of bipolar depression to mania upregulated the rat brain AA cascade. These observations suggest that the brain AA cascade is a common target of mood stabilizers, and that bipolar symptoms, particularly mania, are associated with an upregulated cascade and excess AA signaling via D2-like and NMDA receptors. This review presents ways to test these suggestions. PMID:19555719

    The initial onset of bipolar disorder occurs in childhood or adolescence in about 50% of patients. Early-onset forms of the disorder have a poorer prognosis than adult-onset forms and are frequently characterized by comorbid substance abuse. Clinical trials research suggests that family psychoeducational approaches are effective adjuncts to medication in stabilizing the symptoms of bipolar disorder in adults and youth, although their efficacy in patients with comorbid substance use disorders has not been systematically investigated. This article describes the family-focused treatment (FFT) of a late adolescent with bipolar disorder and polysubstance dependence. The treatment of this patient and family required adapting FFT to consider the family’s structure, dysfunctional alliance patterns, and unresolved conflicts from early in the family’s history. The case illustrates the importance of conducting manual-based behavioral family treatments with a psychotherapeutic attitude, including addressing unstated emotional conflicts and resistances that may impede progress.

    Although extensive literature supports connections between bipolar disorder and creativity, possible mechanisms underlying such relationships are only beginning to emerge. Herein we review evidence supporting one such possible mechanism, namely that personality/temperament contribute to enhanced creativity in individuals with bipolar disorder, a theory supported by studies showing that certain personality/temperamental traits are not only common to bipolar disorder patients and creative individuals but also correlate with measures of creativity. Thus, we suggest based on studies using three important personality/temperament measures-the Neuroticism, Extraversion, and Openness Personality Inventory (NEO); the Myers-Briggs Type Indicator (MBTI); and the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A)-that changeable (increased TEMPS-A-cyclothymia) and at times negative (increased NEO-neuroticism) affect and open-minded (increased NEO-openness) and intuitive (increased MBTI-intuition) cognition may contribute importantly to enhanced creativity in individuals with bipolar disorder.

    Aim To review the diagnosis and the pharmacologic and psychosocial interventions for pediatric bipolar disorder (PBD). Methods A comprehensive literature review of studies discussing the diagnosis and treatment of PBD was conducted. Results A context for understanding controversies and difficulties in the diagnosis of PBD is provided. An evidence-based assessment protocol for PBD is reviewed. The evidence for the following three categories of pharmacologic interventions are reviewed: Lithium, antiepileptics, and second generation antipsychotics. Algorithms for medication decisions are briefly reviewed. Existing psychosocial treatments and the evidence for those treatments are also reviewed. Conclusion Despite recent developments in understanding the phenomenology of PBD and in identifying pharmacologic and psychosocial interventions, critical gaps remain. PMID:21822352

    It was previously shown that available mood stabilisers are used to treat bipolar depression. As part of the natural course of illness, patients with bipolar disorder often suffer from episodes of depression more frequently and for longer durations than mania. A major challenge in the treatment of bipolar depression is the tendency for antidepressant medications, particularly tricyclic antidepressants, to precipitate episodes of mania, or to increase cycle frequency or symptom intensity. Thus, exploring the utility of mood stabilisers as monotherapy for bipolar depression is important. The aim of this review it to collate data involving the effects of some mood stabilisers like lithium, carbamazepine, valproate and lamotrigine in depressive aspects of bipolar disorder, but as well using an animal model of depression, to understand their mechanism of action.

    Bipolar disorder (BD) is a common neuropsychiatric disorder characterized by chronic recurrent episodes of depression and mania. Despite evidence for high heritability of BD, little is known about its underlying pathophysiology. To develop new tools for investigating the molecular and cellular basis of BD we applied a family-based paradigm to derive and characterize a set of 12 induced pluripotent stem cell (iPSC) lines from a quartet consisting of two BD-affected brothers and their two unaffected parents. Initially, no significant phenotypic differences were observed between iPSCs derived from the different family members. However, upon directed neural differentiation we observed that CXCR4 (CXC chemokine receptor-4) expressing central nervous system (CNS) neural progenitor cells (NPCs) from both BD patients compared to their unaffected parents exhibited multiple phenotypic differences at the level of neurogenesis and expression of genes critical for neuroplasticity, including WNT pathway components and ion channel subunits. Treatment of the CXCR4+ NPCs with a pharmacological inhibitor of glycogen synthase kinase 3 (GSK3), a known regulator of WNT signaling, was found to rescue a progenitor proliferation deficit in the BD-patient NPCs. Taken together, these studies provide new cellular tools for dissecting the pathophysiology of BD and evidence for dysregulation of key pathways involved in neurodevelopment and neuroplasticity. Future generation of additional iPSCs following a family-based paradigm for modeling complex neuropsychiatric disorders in conjunction with in-depth phenotyping holds promise for providing insights into the pathophysiological substrates of BD and is likely to inform the development of targeted therapeutics for its treatment and ideally prevention.

    Early identification and treatment are associated with improved outcomes in bipolar disorder (BPD) and schizophrenia (SCZ). Screening for the presence of these disorders usually involves time-intensive interviews that may not be practical in settings where mental health providers are limited. Thus, individuals at earlier stages of illness are often not identified. The Washington Early Recognition Center Affectivity and Psychosis (WERCAP) screen is a self-report questionnaire originally developed to identify clinical risk for developing bipolar or psychotic disorders. The goal of the current study was to investigate the utility of the WERCAP Screen and two complementary questionnaires, the WERC Stress Screen and the WERC Substance Screen, in identifying individuals with established SCZ or BPD. Participants consisted of 35 BPD and 34 SCZ patients, as well as 32 controls (CON), aged 18-30 years. Univariate analyses were used to test for score differences between groups. Logistic regression and receiver operating characteristic (ROC) curves were used to identify diagnostic predictors. Significant group differences were found for the psychosis section of the WERCAP (pWERCAP; p < 0.001), affective section of the WERCAP (aWERCAP; p = 0.001), and stress severity (p = 0.027). No significant group differences were found in the rates of substance use as measured by the WERC Substance Screen (p = 0.267). Only the aWERCAP and pWERCAP scores were useful predictors of diagnostic category. ROC curve analysis showed the optimal cut point on the aWERCAP to identify BPD among our participant groups was a score of >20 [area under the curve (AUC): 0.87; sensitivity: 0.91; specificity: 0.71], while that for the pWERCAP to identify SCZ was a score of >13 (AUC: 0.89; sensitivity: 0.88; specificity: 0.82).

    Cognitive dysfunction is a core feature of schizophrenia and is also present in bipolar disorder (BD). Whereas decreased intelligence precedes the onset of psychosis in schizophrenia and remains relatively stable thereafter; high intelligence is a risk factor for bipolar illness but cognitive function decreases after onset of symptoms. While in schizophrenia, many studies have been conducted on the development of cognitive enhancing agents; in BD such studies are almost non-existent. This review focuses on the pharmacological agents with putative effects on cognition in both schizophrenia and bipolar illness; specifically agents targeting the dopaminergic, cholinergic and glutamatergic neurotransmitter pathways in schizophrenia and the cognitive effects of lithium, anticonvulsants and antipsychotics in BD. In the final analysis we conclude that cognitive enhancing agents have not yet been produced convincingly for schizophrenia and have hardly been studied in BD. Importantly, studies should focus on other phases of the illness. To be able to treat cognitive deficits effectively in schizophrenia, patients in the very early stages of the illness, or even before - in the ultra-high risk stages - should be targeted. In contrast, cognitive deficits occur later in BD, and therefore drugs should be tested in BD after the onset of illness. Hopefully, we will then find effective drugs for the incapacitating effects of cognitive deficits in these patients.

    Previous research on functional outcome in bipolar disorder (BD) has uncovered various factors that exacerbate psychosocial disability over the course of illness, including genetics, illness severity, stress, anxiety, and cognitive impairment. This paper presents an integrated view of these findings that accounts for the precipitous decline in psychosocial functioning after illness onset. The proposed model highlights a number of reciprocal pathways among previously studied factors that trap people in a powerful cycle of ailing forces. The paper discusses implications to patient care as well as the larger social changes required for shifting the functional trajectory of people with BD from psychosocial decline to growth.

    Bupropion is widely used for treating bipolar disorder (BD), and especially those with depressive mood, based on its good treatment effect, safety profile, and lower risk of phase shifting. However, increasing evidence indicates that the safety of bupropion in BD patients may not be as good as previously thought. The aim of this study was to summarize data on the treatment effect and safety profile of bupropion in the treatment of BD via a meta-analysis. Electronic search through PubMed and ClinicalTrials.gov was performed. The inclusion criteria were: (i) studies comparing changes in disease severity before and after bupropion treatment or articles comparing the treatment effect of bupropion in BD patients with those receiving other standard treatments; (ii) articles on clinical trials in humans. The exclusion criteria were (i) case reports/series, and (ii) nonclinical trials. All effect sizes from 10 clinical trials were pooled using a random effects model. We examined the possible confounding variables using meta-regression and subgroup analysis. Bupropion significantly improved the severity of disease in BD patients (P < 0.001), and the treatment effect was similar to other antidepressants/standard treatments (P = 0.220). There were no significant differences in the dropout rate (P = 0.285) and rate of phase shifting (P = 0.952) between BD patients who received bupropion and those who received other antidepressants. We could not perform a detailed meta-analysis of every category of antidepressant, nor could we rule out the possible confounding effect of concurrent psychotropics or include all drug side effects. Furthermore, the number of studies recruited in the meta-analysis was relatively small. Our findings reconfirm the benefits of bupropion for the treatment of bipolar depression, which are similar to those of other antidepressants.

This would be expected to result in increased anger and reward sensitivity, both of which are related to the approach system. This study examined these predictions through the use of tasks that assess different aspects of the BAS: reward sensitivity, anger and impulsivity. These characteristics were assessed using the probabilistic classification task (PCT), ultimatum game (UG) and single key impulsivity paradigm (SKIP), respectively. Participants were euthymic adult bipolar disorder patients (BP; N=40) and healthy controls (HC; N=41). In the UG, all participants showed the standard pattern of rejecting overtly unfair offers and accepting clearly fair offers; however, BPs rejected more of the moderately unfair offers than did HCs. BP and HC participants did not differ on their ability to learn, but did show different patterns of learning from reward and punishment. Learning for reward and punishment were negatively correlated in the BP group, suggesting that individuals could learn well either from reward or punishment, but not both. No correlation was found between these forms of learning in the HC group. BP patients show signs of their disorder even in the euthymic state, as seen by the dysbalance between reward and punishment learning and their residual anger in the UG.

    Background North American studies show bipolar disorder is associated with elevated rates of problem gambling; however, little is known about rates in the different presentations of bipolar illness. Aims To determine the prevalence and distribution of problem gambling in people with bipolar disorder in the UK. Method The Problem Gambling Severity Index was used to measure gambling problems in 635 participants with bipolar disorder. Results Moderate to severe gambling problems were four times higher in people with bipolar disorder than in the general population, and were associated with type 2 disorder (OR = 1.74, P = 0.036), history of suicidal ideation or attempt (OR = 3.44, P = 0.02) and rapid cycling (OR = 2.63, P = 0.008). Conclusions Approximately 1 in 10 patients with bipolar disorder may be at moderate to severe risk of problem gambling, possibly associated with suicidal behaviour and a rapid cycling course. Elevated rates of gambling problems in type 2 disorder highlight the probable significance of modest but unstable mood disturbance in the development and maintenance of such problems. PMID:26089303

    Callosal volume reduction has been observed in patients with bipolar disorder, but whether these deficits reflect genetic vulnerability to the illness remains unresolved. Here, we used computational methods to map corpus callosum abnormalities in a population-based sample of twin pairs discordant for bipolar disorder. Twenty-one probands with bipolar I disorder (mean age 44.4 ± 7.5 years; 48% female), 19 of their non-bipolar co-twins, and 34 demographically matched control twin individuals underwent magnetic resonance imaging. Three-dimensional callosal surface models were created to visualize its morphologic variability and to localize group differences. Neurocognitive correlates of callosal area differences were additionally investigated in a subsample of study participants. Bipolar (BPI) probands, but not their co-twins, showed significant callosal thinning and area reduction, most pronounced in the genu and splenium, relative to healthy twins. Altered callosal curvature was additionally observed in BPI probands. In bipolar probands and co-twins, genu and splenium midsagittal areas were significantly correlated with verbal processing speed and response inhibition. These findings suggest that aberrant connections between cortical regions--possibly reflecting decreased myelination of white matter tracts--may be involved in bipolar pathophysiology. However, findings of callosal thinning appear to be disease related, rather than reflecting genetic vulnerability to bipolar illness. PMID:21383237

    Background Migraine is a common comorbidity among individuals with bipolar disorder, but the underlying mechanisms for this co-occurrence are poorly understood. The aim of this study was to investigate the genetic background of bipolar patients with and without migraine. Methods We performed a genome-wide association analysis contrasting 460 bipolar migraneurs with 914 bipolar patients without migraine from the Bipolar Genome Study (BiGS). Results We identified one genome-wide significant association between migraine in bipolar disorder patients and rs1160720, an intronic single nucleotide polymorphism (SNP) in the NBEA gene (P= 2.97×10-8, OR: 1.82, 95% CI: 1.47-2.25), although this was not replicated in a smaller sample of 289 migraine cases. Limitations Our study is based on self-reported migraine. Conclusions NBEA encodes neurobeachin, a scaffolding protein primarily expressed in the brain and involved in trafficking of vesicles containing neurotransmitter receptors. This locus has not previously been implicated in migraine per se. We found no evidence of association in data from the GWAS migraine meta-analysis consortium (n=118 710 participants) suggesting that the association might be specific to migraine co-morbid with bipolar disorder.

    Objectives To determine the longitudinal impact of Borderline Personality Disorder (BPD) on the course and outcome of Bipolar Disorder (BP) in a pediatric BP sample. Method Participants (N=271) and parents from the Course and Outcome of Bipolar Youth (COBY) study were administered structured clinical interviews and self-reports on average every 8.7 months over a mean of 93 months starting at age 13.0 +/- 3.1 years. The Structured Interview for DSM-IV Personality Disorders (SIDP-IV) was administered at the first follow-up after age 18 to assess for symptoms of BPD. BPD operationalized at the disorder, factor, and symptom level, was examined as a predictor of poor clinical course of BP using all years of follow-up data. Results The number of BPD symptoms was significantly associated with poor clinical course of BP, above and beyond BP characteristics. Affective dysregulation was most strongly associated with poor course at the factor level; the individual symptoms most strongly associated with poor course were dissociation/stress-related paranoid ideation, impulsivity, and affective instability. Conclusions BPD severity adds significantly to the burden of BP illness and is significantly associated with a more chronic and severe course and outcome beyond what can be attributable to BP characteristics.

    Bipolar disorder is manifested as severe dysregulation of mood with recurrent manic and major depressive episodes. It is associated with psychiatric and medical comorbidities, inadequate response to currently available pharmacological agents and a progressively deteriorating course in many patients. The index episode is often depressive in nature, while the first manic or hypomanic episode may occur several years later in the course of the disorder causing delay in diagnosis and use of inappropriate treatment strategies. Staging has been used to great advantage in other branches of medicine like cardiology and oncology. There is growing realization that major mental disorders are fundamentally progressive, with simpler treatment requirements and better prognosis during initial stages of the illness. Defining these conditions into clinically applicable stages not only helps in better understanding the trajectory of a particular disorder, but also assists in management. Patients with a chronic, recalcitrant condition like bipolar disorder are likely to greatly benefit from this approach. If the illness is correctly identified early in its course, proper treatment can be instigated arresting progression to latter phases which are associated with myriad complications in the biopsychosocial realm. With these considerations, a search of the MEDLINE data base was conducted to seek out literature pertaining to staging models in bipolar disorder. A thorough scrutiny of the existing research work revealed that a number of investigators have endeavored to stage define bipolar disorder. This paper outlines staging proposals for bipolar disorder which have the greatest supporting evidence in the literature. PMID:27121423

    A century of investigations enhanced our understanding of bipolar disorder although it remains a complex multifactorial disorder with a mostly unknown pathophysiology and etiology. The role of the immune system in this disorder is one of the most controversial topics in genetic psychiatry. Though inflammation has been consistently reported in bipolar patients, it remains unclear how the immunologic process influences the disorder. One of the core components of the immune system is the NF-κB pathway, which plays an essential role in the development of innate and adaptive immunity. Remarkably, the NF-κB pathway received only little attention in bipolar studies, as opposed to studies of related psychiatric disorders where immune dysregulation has been proposed to explain the neurodegeneration in patient conditions. If immune dysregulation can also explains the neurodegeneration in bipolar disorder, it will underscore the role of the immune system in the chronicity and pathophysiology of the disorder and may promote personalized therapeutic strategies. This is the first review to summarize the current knowledge of the pathophysiological functions of NF-κB in bipolar disorder.

    Bipolar disorder (BD) is a chronic, debilitating disorder with recurrent manic and depressive episodes. Over 75% of bipolar patients have a current or lifetime diagnosis of a comorbid anxiety disorder. Comorbid anxiety in BD is associated with greater illness severity, greater functional impairment, and poorer illness-related outcomes. Effectively treating comorbid anxiety in individuals with BD has been recognized as one of the biggest unmet needs in the field of bipolar disorder. Recently, the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) was developed to be applicable to the full range of anxiety and mood disorders, based upon converging evidence from genetics, cognitive and affective neuroscience, and behavioral research suggesting common, core emotion-related pathology. Here, we present a preliminary evaluation of the efficacy of the UP for the treatment of BD with comorbid anxiety, in a clinical replication series consisting of three cases. PMID:22822175

Design A 27-year longitudinal (1981-2008) observational study ofmood disorders (Research Diagnostic Criteria diagnoses based on Schedule Dr Afi:ctive Disorders and Schizophrenia and review ofmedical records) was used to evaluate antidepressants and risk Dr suicidal behavior. Mixed-efi:cts logistic regression models examined propensity Dr antidepressant exposure. Mixed-efi:cts swvival models that were matched on the propensity score examined exposure status as a risk factor for time until suicidal behavior. Setting Five US academic medical centers. Results Analyses of206 participants with bipolar I disorder revealed 2,010 exposure intervals (980 exposed to antidepressants; 1,030 unexposed); 139 participants with bipolar II disorder had 1 ,407 exposure intervals (694 exposed; 713 unexposed); and 361 participants with unipolar depressive disorder had 2, 745 exposure intervals (1,328 exposed; 1,417 unexposed). Propensity score analyses confinned that more severely ill participants were more likely to initiate antidepressant treatment. In mixed-elects swvival analyses, those with bipolar I disorder had a significant reduction in risk of suicidal behavior by 54% (HR = 0.46; 95% CI, 0.31-0.69; t = -3.74; P < .001) during periods of antidepressant exposure compared to propensity-matched unexposed intervals. Similarly, the risk was reduced by 35% (HR = 0.65; 95% CI, 0.43-0.99; t = −2.01; P = .045) in bipolar II disorder. By contrast, there was no evidence of an increased or decreased risk with antidepressant exposure in unipolar disorder. Condusions Based on obsetVational data adjusted Dr propensity to receive antidepressants, antidepressants may protect patients with bipolar disorders but not unipolar depressive disorder from suicidal behavior.

    Bipolar disorder (BD) is associated with alterations of cytokines in the immune system. The aim of this study was to assess the serum levels of TNF-α, IL-6 and IL-18 in manic, depressive, mixed state patients of BD. The correlations between the serum cytokines levels with the demographic characteristics and the psychiatric symptoms were also assessed. We measured serum TNF-α, IL-6 and IL-18 levels using an enzyme-linked immunosorbent assay (ELISA) from 59 BD patients (37 in manic state, 12 in depressive state, 10 in mixed state) and 80 healthy control subjects. The psychotic symptoms of BD were assessed using the Hamilton Depression Scale (HAMD) and the Young Mania Rating Scale (YMRS). The results showed that serum TNF-α and IL-6 levels in manic, depressive and mixed state BD patients were significantly higher than that in controls, while serum IL-18 level was only significantly higher in depressive patients. Serum IL-6 level was significantly positively correlated with YMRS scores in manic episode as well as in mixed episode. When gender and age were added as potentially confounding covariate terms, the differences between controls and each mood state patients were still significant. Our findings provided additional evidence that elevated TNF-α, IL-6 and IL-18 pathway activities may be involved in the psychopathology of BD. Due to the lack of controlling important confounding factors, such as BMI, smoking status and alcohol use, further studies are required to confirm the roles of TNF-α, IL-6 and IL-18. PMID:27455146

    The identification of early markers has become a focus for early intervention in bipolar disorder. Using a retrospective, qualitative methodology, the present study compares the early experiences of participants with bipolar disorder to those with unipolar depression up until their first diagnosed episode. The study focuses on differences in early home and school environments as well as putative differences in personality characteristics between the two groups. Finally we a compare and contrast prodromal symptoms in these two populations. Thirty-nine participants, 20 diagnosed with unipolar depression and 19 diagnosed with bipolar disorder, took part in the study. A semi-structured interview was developed to elicit information about participants' experiences prior to their first episode. Participants with bipolar disorder reported disruptive home environments, driven personality features, greater emotion dysregulation and adverse experiences during the school years, whereas participants with depression tended to describe more supportive home environments, and more compliant and introvert personality traits. Retrospective data collection and no corroborative evidence from other family members. No distinction was made between bipolar I and bipolar II disorder nor between melancholic and non-melancholic depression in the sample. Finally the study spanned over a 12-month period which does not allow for the possibility of diagnostic reassignment of some of the bipolar participants to the unipolar condition. These findings indicate that there may be benefits in combining both proximal and distal indicators in identifying a bipolar disorder phenotype which, in turn, may be relevant to the development of early intervention programs for young people with bipolar disorder.

    Persistent cognitive impairment in the euthymic state of bipolar disorder is increasingly recognized. Mounting evidence also suggests an association between neuroinflammation and cognitive dysfunction. The purpose of this study was to test if cerebrospinal fluid (CSF) markers of neuroinflammation could account for cognitive impairment in bipolar disorder. Hierarchical linear regression models were applied to account for performance in five cognitive domains using CSF neuroinflammatory biomarkers as predictors in patients with bipolar disorder type I and II (N=78). The associations between these biomarkers and cognition were further tested in healthy age- and sex-matched controls (N=86). In patients with bipolar disorder, the CSF biomarkers accounted for a significant proportion of the variance in executive functions (42.8%, p=<.0005) independently of age, medication, disease status, and bipolar subtype. The microglial marker YKL-40 had a high impact (beta=-.99), and was the only biomarker that contributed individually. CSF biomarkers were not associated with cognitive performance in healthy controls. The CSF neuroinflammation biomarker YKL-40 is associated with executive performance in euthymic bipolar disorder, but not in healthy controls.

    Treating pregnant women with bipolar disorder is among the most challenging clinical endeavors. Patients and clinicians are faced with difficult choices at every turn, and no approach is without risk. Stopping effective pharmacotherapy during pregnancy exposes the patient and her baby to potential harms related to bipolar relapses and residual mood symptom-related dysfunction. Continuing effective pharmacotherapy during pregnancy may prevent these occurrences for many; however, some of the most effective pharmacotherapies (such as valproate) have been associated with the occurrence of congenital malformations or other adverse neonatal effects in offspring. Very little is known about the reproductive safety profile and clinical effectiveness of atypical antipsychotic drugs when used to treat bipolar disorder during pregnancy. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated or undertreated maternal bipolar disorder during pregnancy, the effectiveness of interventions for bipolar disorder management during pregnancy, and potential obstetric, fetal, and neonatal risks associated with core foundational pharmacotherapies for bipolar disorder.

    Objectives Emotion regulation deficits are a core feature of bipolar disorder. However, their potential neurobiological underpinnings and existence beyond bipolar I disorder remain unexplored. Our main goal was to investigate whether both individuals with bipolar I and bipolar II disorder show deficits in emotion regulation during an attention control task, and to explore the neurophysiological underpinnings of this potential deficit. Methods Twenty healthy controls, 16 euthymic participants with bipolar I disorder, and 19 euthymic participants with bipolar II disorder completed psychometric and clinical assessments, a neuroimaging emotion regulation paradigm, and an anatomical diffusion-weighted scan. Groups were matched for age, gender, and verbal IQ. Results During the presence of emotional distracters, subjects with bipolar I disorder showed slowed reaction times to targets, and increased blood oxygenation level-dependent (BOLD) responses in the amygdala, accumbens, and dorsolateral prefrontal cortex, but not increased inverse functional connectivity between these prefrontal and subcortical areas, and altered white matter microstructure organization in the right uncinate fasciculus. Subjects with bipolar II disorder showed no altered reaction times, increased BOLD responses in the same brain areas, increased inverse functional connectivity between the prefrontal cortex and amygdala, and no abnormalities in white matter organization. Conclusions Participants with bipolar I disorder showed abnormalities in functional and anatomical connectivity between prefrontal cortices and subcortical structures in emotion regulation circuitry. However, these deficits did not extend to subjects with bipolar II disorder, suggesting fundamental differences in the pathophysiology of bipolar disorder subtypes. PMID:25771686

    Several lines of evidence implicate dysfunction in brain energy production as a key component of bipolar disorder. In particular, elevated brain lactate levels observed in this condition suggest a shift from aerobic to anaerobic metabolism, possibly as a result of mitochondrial abnormalities. Most prior imaging studies of brain metabolites were performed in either euthymic or depressed bipolar patients or compared different populations in different mood states. We sought to measure brain metabolite concentrations in the same patients in both manic and euthymic states. Given the dramatic changes in clinical state of bipolar disorder patients, we hypothesized that previously observed abnormalities in lactate concentrations in bipolar disorder might show state dependent changes. In this study 15 patients (mean age 36.1 years) diagnosed with bipolar I disorder underwent proton magnetic resonance spectroscopy of the anterior cingulate cortex and parieto-occipital cortex during hospitalization for acute mania (mean Young Mania Rating Scale (YMRS) 22.1). Seven of these subjects returned (mean interval 21.16 months) to have imaging repeated while euthymic (mean YMRS 2.0). A group of age- and gender-matched control participants (N=6) were scanned as well. We report that during mania, bipolar disorder subjects had lactate levels comparable to healthy control subjects but during euthymia these levels were significantly reduced. No significant change was observed for other metabolites. These results implicate mood dependent alterations in energy metabolism in the biology of bipolar disorder. Additionally, this finding has potential use as a biomarker for both evaluating novel treatments as well as diagnostic clarification between mood disorders. PMID:22968227

    We examined whether the patients with Bipolar Disorder (BD) and Obsessive-Compulsive Disorder (OCD) comorbidity may represent a distinct form of BD. The subjects diagnosed with BD (n=48), OCD (n=61), and BD with OCD (n=32) were compared in terms of several socio-demographic and clinical characteristics. Previous history of suicidal attempts was more likely to be higher in BD-OCD group compared to the other two groups. A more episodic course of OCD, higher rates of rapid cycling, and the seasonality were found in BD-OCD patients. The frequency of bipolar II and NOS subtypes was more prevalent in patients with BD-OCD than in OCD patients. The first diagnosed illness was BD in the majority of BD-OCD cases. It was found that first affective episode was major depression in half of BD-OCD patients. Age at onset of BD was found to be earlier in BD-OCD group compared to pure BD patients. Bipolarity may not have a specific effect on the phenomenology of OC symptoms. The episodic course of OCD, seasonality, rapid cycling, earlier onset of BD, and impulsivity in BD-OCD patients may be indicative for a distinct form of BD. PMID:26561371

    Cognitive changes are documented in bipolar disorder (BP). Cortical volume loss, especially in prefrontal regions, has also been reported, but associations between cognition and cortical abnormalities have not been fully documented. This study explores associations between cognitive performance and cortical parameters (area, thickness and volume) of the fronto-temporal cortex in 36 BP patients (25 BPI and 11 BPII). T1-weighted volumetric MRI images were obtained using a 1.5 Tesla scanner. Cortical parameters were measured using surface-based morphometry and their associations with estimated premorbid, current IQ, visual memory, and executive function explored. Premorbid IQ was associated with frontal cortical area and volume, but no such associations were present for current cognitive performance. Cortical parameters were not different in BPI and BPII patients, but the association between current IQ and temporal cortical area was stronger in BPII patients. The pattern of cortico-cognitive associations in BPI and BPII patients merits further consideration. PMID:22264359

A biomarker able to differentiate BD and MDD could help clinicians avoid risks of treating BD with antidepressants without mood stabilizers. Methods Cortical thickness differences were assessed using magnetic resonance imaging in BD depressed patients (n = 18), MDD depressed patients (n = 56), and healthy volunteers (HVs) (n = 54). A general linear model identified clusters of cortical thickness difference between diagnostic groups. Results Compared to the HV group, the BD group had decreased cortical thickness in six regions, after controlling for age and sex, located within frontal and parietal lobes, and posterior cingulate cortex. Mean cortical thickness changes in clusters ranged from 7.6–9.6% (cluster wise p-values from 1.0 e−4 to 0.037). When compared to MDD, three clusters of lower cortical thickness in BD were identified that overlapped with clusters that differentiated the BD and HV groups. Mean cortical thickness changes in the clusters ranged from 7.5–8.2% (cluster wise p-values from 1.0 e−4 to 0.023). The difference in cortical thickness was more pronounced when the subgroup of subjects with bipolar I disorder (BD-I) was compared to the MDD group. Conclusions Cortical thickness patterns were distinct between BD and MDD. These results are a step toward developing an imaging test to differentiate the two disorders. PMID:24428430

    The notion that healthy brain function emerges from coordinated neural activity constrained by the brain's network of anatomical connections--i.e., the connectome--suggests that alterations in the connectome's wiring pattern may underlie brain disorders. Corroborating this hypothesis, studies in schizophrenia are indicative of altered connectome architecture including reduced communication efficiency, disruptions of central brain hubs, and affected "rich club" organization. Whether similar deficits are present in bipolar disorder is currently unknown. This study examines structural connectome topology in 216 bipolar I disorder patients as compared to 144 healthy controls, focusing in particular on central regions (i.e., brain hubs) and connections (i.e., rich club connections, interhemispheric connections) of the brain's network. We find that bipolar I disorder patients exhibit reduced global efficiency (-4.4%, P =0.002) and that this deficit relates (r = 0.56, P < 0.001) to reduced connectivity strength of interhemispheric connections (-13.0%, P = 0.001). Bipolar disorder patients were found not to show predominant alterations in the strength of brain hub connections in general, or of connections spanning brain hubs (i.e., "rich club" connections) in particular (all P > 0.1). These findings highlight a role for aberrant brain network architecture in bipolar I disorder with reduced global efficiency in association with disruptions in interhemispheric connectivity, while the central "rich club" system appears not to be particularly affected.

    Although schizophrenia (SCZ) and bipolar disorder (BD) share elements of pathology (Ellison-Wright and Bullmore, 2009), the neural mechanisms underlying these disorders are still under investigation. Up until now, many neuroimaging studies investigated the brain structural differences of SCZ and BD compared with healthy controls (HC), trying to identify the possible neuroanatomical markers for the two disorders. However, just a few studies focused on the brain structural changes between the two diagnoses. The present review summarises the findings of the voxel-based grey matter (GM) comparisons between SCZ and BD, with the objective to highlight the possible consistent anatomical differences between the two disorders. While the comparisons between patients and HC highlighted overlapping areas of GM reduction in insula and anterior cingulate cortex, the SCZ-BD comparisons suggest the presence of more generalised GM deficits in SCZ compared with BD. Indeed, in a number of studies, SCZ patients showed lower GM volumes than BD patients in fronto-temporal cortex, thalamus, hippocampus and amygdala. Conversely, only a couple of studies reported GM deficits in BD compared with SCZ, both at the level of cerebellum. In summary, the two disorders exhibit both common and specific neuroanatomical characteristics, whose knowledge is mandatory to develop innovative diagnostic and treatment strategies. PMID:27095442

  1. Case report: bipolar disorder as the first manifestation of CADASIL

    2014-01-01

    Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebrovascular disease, clinically characterized by variable manifestations of migraine, recurrent transient ischemic attack or lacunar strokes, cognitive decline, and mood disturbances. However, manic episodes have rarely been documented as an initial symptom of CADASIL and bipolar disorder presenting as the first manifestation in CADASIL has not been reported previously from evaluations by psychiatrists or psychological testing by psychologists. Case presentation A 53 year old woman developed symptoms of mania in her 50s leading to a personality change involving a continuously labile mood and irritability over a number of years. Neuropsychological testing revealed an intact memory, but impairment in attention and executive function. In the Rorschach test, she showed a high level of cognitive rigidity. Magnetic resonance imaging findings were very consistent with a diagnosis of CADASIL, which was confirmed by genetic testing for NOTCH3 mutations. Atypical antipsychotics proved to be helpful in treating her manic symptoms and for behavior control. Conclusion We present a novel case of CADASIL that first presented as bipolar disorder. We contend that when patients show a late onset personality change or chronically irritable mood that deteriorates over many years, an organic cause such as CADASIL must be considered. Further studies are needed to better understand the exact impacts of cerebral tissue lesions and psychiatric symptoms in CADASIL patients. PMID:24929957

    Schizophrenia (SCH) is a complex, psychiatric disorder affecting 1 % of population. Its clinical phenotype is heterogeneous with delusions, hallucinations, depression, disorganized behaviour and negative symptoms. Bipolar affective disorder (BD) refers to periodic changes in mood and activity from depression to mania. It affects 0.5-1.5 % of population. Two types of disorder (type I and type II) are distinguished by severity of mania episodes. In our analysis, we aimed to check if clinical and demographical characteristics of the sample are predictors of symptom dimensions occurrence in BD and SCH cases. We included total sample of 443 bipolar and 439 schizophrenia patients. Diagnosis was based on DSM-IV criteria using Structured Clinical Interview for DSM-IV. We applied regression models to analyse associations between clinical and demographical traits from OPCRIT and symptom dimensions. We used previously computed dimensions of schizophrenia and bipolar affective disorder as quantitative traits for regression models. Male gender seemed protective factor for depression dimension in schizophrenia and bipolar disorder sample. Presence of definite psychosocial stressor prior disease seemed risk factor for depressive and suicidal domain in BD and SCH. OPCRIT items describing premorbid functioning seemed related with depression, positive and disorganised dimensions in schizophrenia and psychotic in BD. We proved clinical and demographical characteristics of the sample are predictors of symptom dimensions of schizophrenia and bipolar disorder. We also saw relation between clinical dimensions and course of disorder and impairment during disorder.

    While schizophrenia and bipolar disorder have been assumed to share phenotypic and genotypic features, there is also evidence for overlapping brain structural correlates, although it is unclear whether these relate to shared psychotic features. In this study, we used voxel-based morphometry (VBM8) in 34 schizophrenia patients, 17 euthymic bipolar I disorder patients (with a history of psychotic symptoms), and 34 healthy controls. Our results indicate that compared to healthy controls schizophrenia patients show grey matter deficits (p<0.05, FDR corrected) in medial and right dorsolateral prefrontal, as well as bilaterally in ventrolateral prefrontal and insular cortical areas, thalamus (bilaterally), left superior temporal cortex, and minor medial parietal and parietooccipital areas. Comparing schizophrenia vs. bipolar I patients (p<0.05, FDR corrected) yielded a similar pattern, however, there was an additional significant reduction in schizophrenia patients in the (posterior) hippocampus bilaterally, left dorsolateral prefrontal cortex, and left cerebellum. Compared to healthy controls, the deficits in bipolar I patients only reached significance at p<0.001 (uncorr.) for a minor parietal cluster, but not for prefrontal areas. Our results suggest that the more extensive prefrontal, thalamic, and hippocampal deficits that might set apart schizophrenia and bipolar disorder might not be related to mere appearance of psychotic symptoms at some stage of the disorders.

  6. Economics of atypical antipsychotics in bipolar disorder: a review of the literature.

    Economic evaluations are increasingly being used by policy makers to evaluate the relative costs and benefits of healthcare interventions. These analyses provide economic and clinical evidence to decision makers seeking to make recommendations on treatment alternatives for patients. This article describes the economic evidence on the atypical antipsychotics currently approved for the treatment of bipolar disorder. This area remains under-researched. A literature search identified only six relevant studies of atypical antipsychotics in bipolar disorder: two retrospective database analyses, three economic analyses alongside clinical trials and one cost-effectiveness analysis. Based on the limited available studies, there appears to be no significant difference in healthcare resource use between olanzapine, quetiapine, risperidone and valproate semisodium (divalproex sodium; an antiepileptic drug and a standard treatment for mania associated with bipolar disorder). While a cost-effectiveness study for the UK found haloperidol (a conventional antipsychotic) to be more cost effective than atypical antipsychotics, these results must be considered with caution because of the non-inclusion of adverse effects in the model. No economic data are available for aripiprazole, clozapine or ziprasidone in bipolar disorder. Until more economic evidence becomes available, the economic implications of atypical antipsychotic treatment in patients with bipolar disorder are unlikely to significantly impact on prescribing and treatment patterns. Future economic studies evaluating atypical antipsychotics in bipolar disorder should address the issue of long-term costs and effectiveness to reflect the chronic nature of the disease, the variety of health states that patients may experience and the range of treatments they may receive. A better understanding of the complex interplay between effectiveness, safety, quality of life, adherence and resource use should ultimately contribute to

    Difficulty attending is a common deficit of euthymic bipolar patients. However, it is not known whether this is a global attentional deficit or relates to a specific attentional network. According to the attention network approach, attention is best understood in terms of three functionally and neuroanatomically distinct networks-alerting, orienting, and executive control. In this study, we explored whether and which of the three attentional networks are altered in euthymic Bipolar Disorder (BD). A sample of euthymic BD patients and age-matched healthy controls completed the Attention Network Test for Interactions and Vigilance (ANTI-V) that provided not only a measure of orienting, executive, and alerting networks, but also an independent measure of vigilance (tonic alerting). Compared to healthy controls, BD patients have impaired executive control (greater interference), reduced vigilance (as indexed by a decrease in the d' sensitivity) as well as slower overall reaction times and poorer accuracy. Our results show that deficits in executive attention and sustained attention often persist in BD patients even after complete remission of affective symptoms, thus suggesting that cognitive enhancing treatments programmed to improve these deficits could contribute to improve their functional recovery.

    Introduction Post-stroke emotional incontinence and bipolar disorder are two disorders that involve the dysfunction of brain structures responsible for emotional regulation. The objective of this work is to study the links between these disorders through a clinical case. Case report We present the case of a 43-year-old man without previous psychiatric history who experienced emotional incontinence after cerebrovascular events. He reacted promptly to selective serotonin reuptake inhibitor treatment. However, he experienced his first episode of hypomania after 6 months of antidepressant therapy. Adjunctive therapy with valproic acid and low-dose paroxetine was eventually added, resulting in complete improvement of both emotional incontinence and hypomania after 4 additional months of treatment. Conclusion The clinician should carefully explore any history of premorbid bipolar disorder, personality disorder characterized by mood instability, and family history of bipolar disorder.

    Bipolar disorder (BD) is a chronic psychiatric disorder of public health importance affecting >1% of the Swedish population. Despite progress, patients still suffer from chronic mood switches with potential severe consequences. Thus, early detection, diagnosis and initiation of correct treatment are critical. Cultured adipocytes from 35 patients with BD and 38 healthy controls were analysed using signal pathway reporter assays, that is, protein kinase C (PKC), protein kinase A (PKA), mitogen-activated protein kinases (extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK)), Myc, Wnt and p53. The levels of activated target transcriptional factors were measured in adipocytes before and after stimulation with lithium and escitalopram. Variations were analysed in the loci of 25 different single-nucleotide polymorphisms (SNPs). Activation of intracellular signals in several pathways analysed were significantly higher in patients than in healthy controls upon drug stimulation, especially with escitalopram stimulation of PKC, JNK and Myc, as well as lithium-stimulated PKC, whereas no meaningful difference was observed before stimulation. Univariate analyses of contingency tables for 80 categorical SNP results versus diagnoses showed a significant link with the ANK3 gene (rs10761482; likelihood ratio χ(2)=4.63; P=0.031). In a multivariate ordinal logistic fit for diagnosis, a backward stepwise procedure selected ANK3 as the remaining significant predictor. Comparison of the escitalopram-stimulated PKC activity and the ANK3 genotype showed them to add their share of the diagnostic variance, with no interaction (15% of variance explained, P<0.002). The study is cross-sectional with no longitudinal follow-up. Cohorts are relatively small with no medication-free patients, and there are no 'ill patient' controls. It takes 3 to 4 weeks of culture to expand adipocytes that may change epigenetic profiles but remove the possibility of medication effects

  11. The pharmacology of bipolar disorder during pregnancy and breastfeeding.

    Treating bipolar disorder in women during reproduction presents a significant challenge to the physician. The pharmaceutical agents most commonly used for treating bipolar disorder have been associated with adverse effects when used during pregnancy and breastfeeding. Of particular concern has been the association of lithium with cardiac malformations, and the association of carbamazepine and valproate with neural tube defects including spina bifida. Toxicity in neonates has also been reported for the most commonly used mood-stabilising agents. Treatment options for mood stabilisation are either associated with risks of adverse events, have been used less frequently and their associated risks are unknown, or may not provide effective prophylaxis against recurrences of bipolar episodes. However, strategies are available that minimise the risk to the fetus and infant whilst still providing effective prophylaxis against bipolar disorder in the mother. Ideally, a treatment regimen tailored to suit the individual should consider both mother and baby and should be planned prior to conception.

    Although people who experience happiness tend to have better psychological health, people who value happiness to an extreme tend to have worse psychological health, including more depression. We propose that the extreme valuing of happiness may be a general risk factor for mood disturbances, both depressive and manic. To test this hypothesis, we examined the relationship between the extreme valuing of happiness and risk for, diagnosis of, and illness course for bipolar disorder (BD). Supporting our hypothesis, the extreme valuing of happiness was associated with a measure of increased risk for developing BD (Studies 1 and 2), increased likelihood of past diagnosis of BD (Studies 2 and 3), and worse prospective illness course in BD (Study 3), even when controlling for current mood symptoms (Studies 1-3). These findings indicate that the extreme valuing of happiness is associated with and even predicts BD. Taken together with previous evidence, these findings suggest that the extreme valuing of happiness is a general risk factor for mood disturbances. More broadly, what emotions people strive to feel may play a critical role in psychological health.

    Large (>100 kb), rare (<1% in the population) copy number variants (CNVs) have been shown to confer risk for schizophrenia (SZ), but the findings for bipolar disorder (BD) are less clear. In a new BD sample from the United Kingdom (n = 2591), we have examined the occurrence of CNVs and compared this with previously reported samples of 6882 SZ and 8842 control subjects. When combined with previous data, we find evidence for a contribution to BD for three SZ-associated CNV loci: duplications at 1q21.1 (P = 0.022), deletions at 3q29 (P = 0.03) and duplications at 16p11.2 (P = 2.3 × 10−4). The latter survives multiple-testing correction for the number of recurrent large CNV loci in the genome. Genes in 20 regions (total of 55 genes) were enriched for rare exonic CNVs among BD cases, but none of these survives correction for multiple testing. Finally, our data provide strong support for the hypothesis of a lesser contribution of very large (>500 kb) CNVs in BD compared with SZ, most notably for deletions >1 Mb (P = 9 × 10−4).

    Objective Previous studies have suggested an association between CACNA1C and susceptibility of bipolar disorder. In this study, we examined the association of CACNA1C variants with bipolar disorder in the Korean population. Methods We selected 2 CACNA1C single nucleotide polymorphisms (SNPs), namely, rs723672 and rs1051375, based on their functions and minor allele frequencies described in previous studies. Genotypes of these 2 SNPs were analyzed by extracting DNA from blood samples collected from 287 patients with bipolar disorder and 340 healthy controls. Results Genotype frequencies of both rs723672 and rs1051375 SNPs were significantly different in patients and controls (p=0.0462 and 1.732E-14, respectively). Dominant, recessive, and allele models showed significant differences between patients and controls with respect to the rs1051375 SNP (p=1.72E-11, 4.17E-10, 4.95E-16, respectively). Conclusion Our results suggested that CACNA1C SNPs rs723672 and rs1051375 were associated with bipolar disorder in the Korean population. In addition, our results highlighted the importance of CACNA1C in determining susceptibility to bipolar disorder. PMID:27482248

    Introduction Data specific to late-life bipolar disorder (BD) are limited. Current research is sparse and present guidelines are not adapted to this group of patients. Objectives We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment. Methods Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015. Results From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested. Conclusion There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that this group needs an adapted clinical assessment and specific clinical guidelines need to be established.

    2014-01-01

    Background Bipolar I disorder (BD-I) is a chronic mental illness characterized by the presence of one or more manic episodes, or both depressive and manic episodes, usually separated by asymptomatic intervals. Pharmacists can contribute to the management of BD-I, mainly with the use of effective and safe drugs, and improve the patient’s life quality through pharmaceutical care. Some studies have shown the effect of pharmaceutical care in the achievement of therapeutic goals in different illnesses; however, to our knowledge, there is a lack of randomized controlled trials designed to assess the effect of pharmacist intervention in patients with BD. The aim of this study is to assess the effectiveness of the Dader Method for pharmaceutical care in patients with BD-I. Methods/design Randomized, controlled, prospective, single-center clinical trial with duration of 12 months will be performed to compare the effect of Dader Method of pharmaceutical care with the usual care process of patients in a psychiatric clinic. Patients diagnosed with BD-I aged between 18 and 65 years who have been discharged or referred from outpatients service of the San Juan de Dios Clinic (Antioquia, Colombia) will be included. Patients will be randomized into the intervention group who will receive pharmaceutical care provided by pharmacists working in collaboration with psychiatrists, or into the control group who will receive usual care and verbal-written counseling regarding BD. Study outcomes will be assessed at baseline and at 3, 6, 9, and 12 months after randomization. The primary outcome will be to measure the number of hospitalizations, emergency service consultations, and unscheduled outpatient visits. Effectiveness, safety, adherence, and quality of life will be assessed as secondary outcomes. Statistical analyses will be performed using two-tailed McNemar tests, Pearson chi-square tests, and Student’s t-tests; a P value <0.05 will be considered as statistically significant

    Wessa, Michèle; Kanske, Philipp; Linke, Julia

    2014-01-01

    Bipolar disorder (BD) is a severe, chronic disease with a heritability of 60-80%. BD is frequently misdiagnosed due to phenomenological overlap with other psychopathologies, an important issue that calls for the identification of biological and psychological vulnerability and disease markers. Altered structural and functional connectivity, mainly between limbic and prefrontal brain areas, have been proposed to underlie emotional and motivational dysregulation in BD and might represent relevant vulnerability and disease markers. In the present laboratory review we discuss functional and structural neuroimaging findings on emotional and motivational dysregulation from our research group in BD patients and healthy individuals at risk to develop BD. As a main result of our studies, we observed altered orbitofrontal and limbic activity and reduced connectivity between dorsal prefrontal and limbic brain regions, as well as reduced integrity of fiber tracts connecting prefrontal and subcortical brain structures in BD patients and high-risk individuals. Our results provide novel insights into pathophysiological mechanisms of bipolar disorder. The current laboratory review provides a specific view of our group on altered brain connectivity and underlying psychological processes in bipolar disorder based on our own work, integrating relevant findings from others. Thereby we attempt to advance neuropsychobiological models of BD.

    Background & objectives: Though studies have reported high prevalence rates of metabolic syndrome among patients with bipolar disorder (BPAD) and schizophrenia, there is lack of data on the impact of the same on the patients’ life. This study was aimed to assess the lifestyle related factors associated with metabolic syndrome (MetS) and to study the impact of MetS on functioning and quality of life (QOL) in patients with BPAD and schizophrenia. Methods: A total of 102 patients with BPAD and 72 patients with schizophrenia attending the output unit of a tertiary care hospital in north India were evaluated for MetS. These patients were assessed on Health Promoting Lifestyle Profile scale II (HPLP II), World Health Organization QOL -Bref Version (WHOQOL-Bref), Impact of Weight on Quality of Life- Lite version (IWOQOL -Lite), Body weight, Image and Self-esteem Evaluation questionnaire (BWISE), Obesity-related Problem scale (OP scale) and Global Assessment of Functioning (GAF) scale. Results: MetS was associated with lower scores on domains of health responsibility and nutrition habit domain on HPLP-II scale in both groups, and additionally on physical activity and stress management domain in BPAD group. On WHOQOL-Bref, MetS was associated with lower scores on the domains of physical and psychological health in both groups. On IWQOL–Lite, scores on personal distress and self esteem domains were higher in those with obesity in both groups and also on physical activity domain in schizophrenia group. Those with MetS had lower level of functioning as measured by GAF in schizophrenia group. Fulfillment of higher number of criteria of MetS correlated with poorer quality of life and higher problems in both groups. Interpretation & conclusions: Many modifiable lifestyle factors increase the risk of MetS. MetS was found to be associated with poorer QOL in patients with BPAD and schizophrenia; in addition, obesity led to poor self-esteem and excessive personal distress. PMID

    Benzodiazepines are widely prescribed for patients with bipolar disorders in clinical practice, but very little is known about the subtypes of patients with bipolar disorder or aspects of bipolar illness that contribute most to benzodiazepine use. We examined the prevalence of and factors associated with benzodiazepine use among 482 patients with bipolar I or II disorder enrolled in the Bipolar CHOICE study. Eighty-one subjects were prescribed benzodiazepines at study entry and were considered benzodiazepine users. Stepwise logistic regression was used to model baseline benzodiazepine use versus nonuse, using entry and exit criteria of P < 0.1. In bivariate analyses, benzodiazepine users were prescribed a significantly higher number of other psychotropic medications and were more likely to be prescribed lamotrigine or antidepressants as compared with benzodiazepine nonusers. Benzodiazepine users were more likely to have a diagnosis of bipolar I disorder and comorbid anxiety disorder, but not comorbid alcohol or substance use disorders. Benzodiazepine users also had experienced more anxiety and depressive symptoms and suicidality, but not irritability or manic symptoms, than did benzodiazepine nonusers. In the multivariate model, anxiety symptom level (regardless of diagnosis), lamotrigine use, number of concomitant psychotropic medications, college education, and high household income predicted benzodiazepine use. Benzodiazepine use in patients with bipolar disorders is associated with greater illness complexity as indicated by a higher number of concomitant psychotropic medications and higher anxiety symptom burden, regardless of a comorbid anxiety disorder diagnosis. Demographic factors were also important determinants of benzodiazepine use, which may be related to access to care and insurance coverage for benzodiazepines.

    Lithium therapy is the gold standard of treatment for patients with Bipolar Disorder. However, despite its effectiveness, it is a potentially hazardous drug requiring regular monitoring of blood levels to ensure toxic levels are not reached. This paper describes the spectrophotometric analysis of Lithium carbonate in solution as a first step in developing a portable home monitoring device for blood lithium analysis.. Using a high-end spectrophotometer, solutions of lithium carbonate (Li2CO3) have been optically fingerprinted. Preliminary measurements indicate that the ultraviolet region shows a strong distinction between different lithium concentrations. Utilizing second derivative absorption curves, the region of 220 nm to 230 nm demonstrated the ability to differentiate between concentrations representing those found in patients. Furthermore, the method could determine to within a 1-6% accuracy whether an unknown solution of Li2CO3 is either inside or outside the high-end of the therapeutic limit. PMID:25798326

    Bipolar disorder is prevalent, with high risks of disability, substance abuse and premature mortality. Treatment responses typically are incomplete, especially for depressive components, so that many cases can be considered "treatment resistant." We reviewed reports on experimental treatments for such patients: there is a striking paucity of such research, mainly involving small incompletely controlled trials of add-on treatment, and findings remain preliminary. Encouraging results have been reported by adding aripiprazole, bupropion, clozapine, ketamine, memantine, pramipexole, pregabalin, and perhaps tri-iodothyronine in resistant manic or depressive phases. The urgency of incomplete responses in such a severe illness underscores the need for more systematic, simpler, and better controlled studies in more homogeneous samples of patients. PMID:26467409

    Quetiapine extended-release (quetiapine-XR) has been studied in patients with schizophrenia, bipolar mania, bipolar depression, major depressive disorder (MDD), and generalized anxiety disorder (GAD). The purpose of this study was to compare the tolerability and sensitivity of quetiapine-XR among these psychiatric conditions. The discontinuation due to adverse events (DAEs) and reported somnolence in randomized, double-blind, placebo-controlled studies of quetiapine-XR in these psychiatric conditions were examined. The absolute risk reduction or increase and the number needed to treat to benefit (NNTB) or harm (NNTH) for DAEs and reported somnolence of quetiapine-XR ≥ 300 mg/d relative to placebo were estimated. Data from one study in schizophrenia (n=465), one in mania (n=316), one in bipolar depression (n=280), two in refractory MDD (n=624), two in MDD (n=669) and three in GAD (n=1109) were available. The risk for DAEs of quetiapine-XR relative to placebo was significantly increased in bipolar depression (NNTH=9), refractory MDD (NNTH=8), MDD (NNTH=9), and GAD (NNTH=5), but not in schizophrenia and mania. The risk for reported somnolence of quetiapine-XR relative to placebo was significantly increased in schizophrenia (600 mg/d NNTH=15 and 800 mg/d NNTH=11), mania (NNTH=8), bipolar depression (NNTH=4), refractory MDD (NNTH=5), MDD (NNTH=5) and GAD (NNTH=5). These results suggest that patients with GAD had the poorest tolerability during treatment with quetiapine-XR, but they had a similar sensitivity as those with bipolar depression and MDD. Patients with schizophrenia or mania had a higher tolerability and a lower sensitivity than those with bipolar depression, MDD, or GAD.

    Suicide behaviors (ideation, attempts, and completions) are unfortunately common in patients with bipolar disorder. It is estimated that 25 to 50% attempt suicide at least once during their lifetime, and 6% to 19% complete suicide. Risk factors include a family history of suicide, previous suicide attempts, younger age of onset, comorbid psychiatric illnesses, and psychological constructs like hopelessness. Pharmacologic treatment may impact suicidal behaviors, either increasing vulnerability or resilience. Clinicians need to be particularly sensitive to their patient's thoughts and beliefs about death, particularly during stressful times of life or when in a depressive/mixed episode of bipolar disorder.

    Objective To determine if a treatment for interepisode bipolar disorder I patients with insomnia improves mood state, sleep, and functioning. Method Alongside psychiatric care, interepisode bipolar disorder I participants with insomnia were randomly allocated to a bipolar disorder–specific modification of cognitive behavior therapy for insomnia (CBTI-BP; n = 30) or psychoeducation (PE; n = 28) as a comparison condition. Outcomes were assessed at baseline, the end of 8 sessions of treatment, and 6 months later. This pilot was conducted to determine initial feasibility and generate effect size estimates. Results During the 6-month follow-up, the CBTI-BP group had fewer days in a bipolar episode relative to the PE group (3.3 days vs. 25.5 days). The CBTI-BP group also experienced a significantly lower hypomania/mania relapse rate (4.6% vs. 31.6%) and a marginally lower overall mood episode relapse rate (13.6% vs. 42.1%) compared with the PE group. Relative to PE, CBTI-BP reduced insomnia severity and led to higher rates of insomnia remission at posttreatment and marginally higher rates at 6 months. Both CBTI-BP and PE showed statistically significant improvement on selected sleep and functional impairment measures. The effects of treatment were well sustained through follow-up for most outcomes, although some decline on secondary sleep benefits was observed. Conclusions CBTI-BP was associated with reduced risk of mood episode relapse and improved sleep and functioning on certain outcomes in bipolar disorder. Hence, sleep disturbance appears to be an important pathway contributing to bipolar disorder. The need to develop bipolar disorder–specific sleep diary scoring standards is highlighted. Public Health Significance This study suggests that an intervention to improve sleep and circadian functioning reduces risk of relapse and improves sleep and overall functioning among individuals who meet diagnostic criteria for bipolar disorder.

    In recent years, there has been an increasing interest in late-onset mental disorders. Among them, geriatric schizophrenia and bipolar disorder are significant health care risks and major causes of disability. We discussed whether late-onset schizophrenia (LOS) and late-onset bipolar (LOB) disorder can be a separate entity from early-onset schizophrenia (EOS) and early-onset bipolar (EOB) disorder in a subset of late-life schizophrenia or late-life bipolar disorder through neuroimaging studies. A literature search for imaging studies of LOS or LOB was performed in the PubMed database. Search terms used were "(imaging OR MRI OR CT OR SPECT OR DTI OR PET OR fMRI) AND (schizophrenia or bipolar disorder) AND late onset." Articles that were published in English before October 2013 were included. There were a few neuroimaging studies assessing whether LOS and LOB had different disease-specific neural substrates compared with EOS and EOB. These researches mainly observed volumetric differences in specific brain regions, white matter hyperintensities, diffusion tensor imaging, or functional neuroimaging to explore the differences between LOS and LOB and EOS and EOB. The aim of this review was to highlight the neural substrates involved in LOS and LOB through neuroimaging studies. The exploration of neuroanatomical markers may be the key to the understanding of underlying neurobiology in LOS and LOB. PMID:24401535

    Our ability to make sense of information on the potential intentions and dispositions of others is of paramount importance for understanding their communicative intent, and for judging what an appropriate reaction might be. Thus, anything that impinges on this ability has the potential to cause significant social impairment, and compromise an individual's level of functioning. Both bipolar disorder and schizophrenia are known to feature theory of mind impairment. We conducted a theoretical review to determine the extent and types of theory of mind impairment in bipolar disorder, and evaluate their relationship to medication and symptoms. We also considered possible mediatory mechanisms, and set out to discover what else could be learnt about the impairment in bipolar disorder by comparison to the profile of impairment in schizophrenia. The literature established that in bipolar disorder (i) some form of theory of mind impairment has been observed in all mood states, including euthymia, (ii) the form of theory of mind assessed and task used to make the assessment influence the impairment observed, and (iii) there might be some relationship to cognitive impairment, although a relationship to standard clinical variables was harder to establish. What also became clear in the literature on bipolar disorder itself was the possible relationship of theory of mind impairment to history of psychotic symptoms. Direct comparative studies, including patients with schizophrenia, were thus examined, and provided several important directions for future research on the bases of impairment in bipolar disorder. Particularly prominent was the issue of whether theory of mind impairment could be considered a candidate endophenotype for the psychoses, although current evidence suggests that this may be premature.

    Schizophrenia and bipolar disorder are severe psychiatric disorders that are frequently associated with persistent symptoms and significant dysfunction. While there are a multitude of psychopharmacologic agents are available for treatment of these illnesses, suboptimal response and significant adverse consequences limit their utility. Cariprazine is a new, novel antipsychotic medication with dopamine D2 and D3 partial agonist effects. Its safety and efficacy have been investigated in acute psychosis of schizophrenia, bipolar mania, bipolar depression, and unipolar depression. Efficacy has been demonstrated in schizophrenia and mania. It is unclear if cariprazine is effective in depression associated with unipolar or bipolar illness. Adverse consequences include extrapyramidal symptoms including akathisia, and various gastrointestinal symptoms. The US Food and Drug Administration (FDA) has recently approved cariprazine. This review will provide clinicians with basic information regarding the research program of cariprazine. PMID:27524901

    Bipolar disorder in elderly is probably heterogenous and the age of onset has been considered to be a potential clinical marker of heterogeneity for this disease. Early- and late-onset bipolar disorders share symptoms, but it is not clear whether they have different aetiologies and vulnerabilities. In bipolar disorder one of the most frequent neuroimaging finding is the white matter hyperintensities (WMHs). The disruption caused by WMHs in the connectivity between structures related to mood regulation and cognition in elderly may be responsible for the affective symptomatology seen in these patients. White matter hyperintensities are found both in late onset patients and in early age onset bipolar patients. It is likely that the aetiology of the white matter hyperintensities in late-onset bipolar disorder be multifactorial, although cardiovascular changes in particular seem to contribute to their physiopathology. In early life onset the aetiology of these lesions is less clear, although probably genetic factors are more important than cardiovascular factors. Understanding the aetiopathogenesis is of key importance when dealing with this disease. PMID:21872409

    Pediatric bipolar disorder (BD) rates have notably increased over the past three decades. Given the significant morbidity and mortality associated with BD, efforts are needed to identify factors useful in earlier detection to help address this serious public health concern. Sleep is particularly important to consider given the sequelae of disrupted sleep on normative functioning and that sleep is included in diagnostic criteria for both Major Depressive and Manic Episodes. Here, we examine one component of sleep—i.e., circadian phase preference with the behavioral construct of morningness/eveningness (M/E). In comparing 30 BD and 45 typically developing control (TDC) participants, ages 7–17 years, on the Morningness-Eveningness Scale for Children (MESC), no between-group differences emerged. Similar results were found when comparing three groups (BD−ADHD; BD+ADHD; TDC). Consistent with data available on circadian phase preference in adults with BD, however, we found that BD adolescents, ages 13 years and older, endorsed significantly greater eveningness compared to their TDC peers. While the current findings are limited by reliance on subjective report and the high-rate of comorbid ADHD among the BD group, this finding that BD teens demonstrate an exaggerated shift towards eveningness than would be developmentally expected is important. Future studies should compare the circadian rhythms across the lifespan for individuals diagnosed with BD, as well as identify the point at which BD youth part ways with their healthy peers in terms of phase preference. In addition, given our BD sample was overall euthymic, it may be that M/E is more state vs. trait specific in latency age youth. Further work would benefit from assessing circadian functioning using a combination of rating forms and laboratory-based measures. Improved understanding of sleep in BD may identify behavioral targets for inclusion in prevention and intervention protocols. PMID:26237260

    Psychiatric disorders are genetically complex and represent the end product of multiple biological and social factors. Links between genes and disorder-related abnormalities can be effectively captured via assessment of phenotypes that are both associated with genetic effects and potentially contributory to behavioral abnormalities. Identifying intermediate or allied phenotypes as a strategy for clarifying genetic contributions to disorders has been successful in other areas of medicine and is a promising strategy for identifying susceptibility genes in complex psychiatric disorders. There is growing evidence that schizophrenia and bipolar disorder, rather than being wholly distinct disorders, share genetic risk at several loci. Further, there is growing evidence of similarity in the pattern of cognitive and neurobiological deficits in these groups, which may be the result of the effects of these common genetic factors. This review was undertaken to identify patterns of performance on neurocognitive and affective tasks across probands with schizophrenia and bipolar disorder as well as unaffected family members, which warrant further investigation as potential intermediate trait markers. Available evidence indicates that measures of attention regulation, working memory, episodic memory, and emotion processing offer potential for identifying shared and illness-specific allied neurocognitive phenotypes for schizophrenia and bipolar disorder. However, very few studies have evaluated neurocognitive dimensions in bipolar probands or their unaffected relatives, and much work in this area is needed. PMID:18448479

    Although bipolar disorder is increasingly recognised as a spectrum of multisystem disorders (ie, bipolar disorders), proposed staging models and theories of bipolar disease progression often fail to incorporate longitudinal data or data from multiple domains of dysfunction. We propose that bipolar disorders are best thought of as syndromes, with different trajectories of development and progression for various symptoms and demographic groups. This inherent complexity might be better suited to non-traditional modelling techniques, potentially derived from chaos theory. In this Personal View, we propose an allostatic load framework to account for biomarkers of physiological symptom progression. We then suggest integration of two potential domains of biobehavioural markers: sleep and wake and circadian rhythm regulation and the behavioural activation system. A satisfactory model should account for the effects of developmental stage as well as demographic characteristics, including but not limited to sex, culture, ethnicity, and socioeconomic status. The ultimate goal of a staging model has to be to inform the development of targeted, stage-appropriate interventions to reduce the substantial burden of bipolar disorders on individuals and societies.

    Objectives Although bipolar disorder has been understood classically as a cyclic disease with full recovery between mood episodes, in the last decade, evidence has accumulated supporting progressive features. The clinical picture of advanced or end-stage bipolar disorder is heterogeneous with possible deficits in cognition and behavior, as illustrated by our case series. Cases From our neuropsychiatric outpatient clinic, we describe four cases with bipolar disorder gradually developing a clinical syndrome, including apathy, disinhibition, loss of empathy, stereotypical behavior, and compulsiveness, fulfilling the criteria for possible behavioral variant frontotemporal dementia. All cases were diagnosed with bipolar 1 disorder at least 10 years before the onset of the current symptoms, which were not due to recent mood episodes or switches of medication. In all cases, 3–7 years of follow-up yielded no progression. Repeated neuroimaging was within normal limits. Cerebrospinal fluid biomarker studies were not supportive of underlying neurodegenerative pathology. C9orf72 mutation status was negative in all cases. Conclusion Symptoms fitting the criteria for possible behavioral variant frontotemporal dementia may be present in end-stage of bipolar disorder. An alternative neurodegenerative nature seems unlikely based on repeated normal neuroimaging and the absence of clinical progression. Functional involvement of the frontal-subcortical networks might play a role.

    Despite evidence that exercise has been found to be effective in the treatment of depression, it is unclear whether these data can be extrapolated to bipolar disorder. Available evidence for bipolar disorder is scant, with no existing randomized controlled trials having tested the impact of exercise on depressive, manic or hypomanic symptomatology. Although exercise is often recommended in bipolar disorder, this is based on extrapolation from the unipolar literature, theory and clinical expertise and not empirical evidence. In addition, there are currently no available empirical data on program variables, with practical implications on frequency, intensity and type of exercise derived from unipolar depression studies. The aim of the current paper is to explore the relationship between exercise and bipolar disorder and potential mechanistic pathways. Given the high rate of medical co-morbidities experienced by people with bipolar disorder, it is possible that exercise is a potentially useful and important intervention with regard to general health benefits; however, further research is required to elucidate the impact of exercise on mood symptomology.

    White matter (WM) abnormalities have been reported in bipolar disorder (BD) patients, as well as in their non-BD relatives, both children and adults. Although it is considered an emerging vulnerability marker for BD, there are no studies investigating WM alterations in pediatric unmedicated patients and young healthy offspring. In this study, we evaluated the presence of WM alterations in 18 pediatric, non medicated BD patients, as well as in 18 healthy offspring of BD type I parents and 20 healthy controls. 3T DT-MRI data were acquired and scans were processed with tract-based spatial statistics to provide measures of fractional anisotropy and diffusivity. We found no significant differences in WM microstructure between BD patients, healthy offspring and healthy controls. Previous studies that reported WM alterations investigated older subjects, either on medication (BD patients) or with psychiatric diagnoses other than BD (unaffected offspring). Our findings highlight the importance of the understanding of disease ontogeny and brain development dynamics in the search for early vulnerability markers for psychiatric disorders.

Subjects were outpatients treated with drugs and psychotherapy in routine office practice. Differences in sexual behavior between the two groups as a whole were minimal, but meaningful differences emerged when subgroups were compared. Compared to control men, Bipolar men had had more partners in the last year and were more likely to have had sex without condoms. Compared to Bipolar females, Bipolar males had more sex partners, had more sex with strangers, and were more likely to have engaged in homosexual behavior. Even so, some patients in the Comparison group also had engaged in risky sexual behavior. They had failed to use condoms and had had sex with strangers and prostitutes during the previous year.

    The emotional and cognitive vulnerabilities that precede the development of bipolar disorder are poorly understood. The inferior frontal gyrus-a key cortical hub for the integration of cognitive and emotional processes-exhibits both structural and functional changes in bipolar disorder, and is also functionally impaired in unaffected first-degree relatives, showing diminished engagement during inhibition of threat-related emotional stimuli. We hypothesized that this functional impairment of the inferior frontal gyrus in those at genetic risk of bipolar disorder reflects the dysfunction of broader network dynamics underlying the coordination of emotion perception and cognitive control. To test this, we studied effective connectivity in functional magnetic resonance imaging data acquired from 41 first-degree relatives of patients with bipolar disorder, 45 matched healthy controls and 55 participants with established bipolar disorder. Dynamic causal modelling was used to model the neuronal interaction between key regions associated with fear perception (the anterior cingulate), inhibition (the left dorsolateral prefrontal cortex) and the region upon which these influences converge, namely the inferior frontal gyrus. Network models that embodied non-linear, hierarchical relationships were the most strongly supported by data from our healthy control and bipolar participants. We observed a marked difference in the hierarchical influence of the anterior cingulate on the effective connectivity from the dorsolateral prefrontal cortex to the inferior frontal gyrus that is unique to the at-risk cohort. Non-specific, non-hierarchical mechanisms appear to compensate for this network disturbance. We thus establish a specific network disturbance suggesting dysfunction in the processes that support hierarchical relationships between emotion and cognitive control in those at high genetic risk for bipolar disorder.

This may occur both due to disruptions within PFC networks and abnormal inhibition over subcortical structures involved in emotional processing. However, no study has examined global PFC dysconnectivity in bipolar disorder and tested if regions with within-PFC dysconnectivity also exhibit fronto-limbic connectivity deficits. Further, no study has investigated whether such connectivity disruptions differ for bipolar patients with psychosis history, who may exhibit a more severe clinical course. Methods We collected resting-state fMRI at 3T in 68 remitted bipolar I patients (34 with psychosis history) and 51 demographically-matched healthy participants. We employed a recently developed Global Brain Connectivity method, restricted to PFC (rGBC). We also independently tested connectivity between anatomically-defined amygdala and PFC. Results Bipolar patients exhibited reduced medial PFC (mPFC) rGBC, increased amygdala-MPFC connectivity, and reduced connectivity between amygdala and dorso-lateral PFC. All effects were driven by psychosis history. Moreover, the magnitude of observed effects was significantly associated with lifetime psychotic symptom severity. Conclusions This convergence between rGBC, seed-based amygdala findings and symptom severity analyses highlights that mPFC, a core emotion regulation region, exhibits both within-PFC dysconnectivity and connectivity abnormalities with limbic structures in bipolar illness. Furthermore, lateral PFC dysconnectivity in patients with psychosis history converges with published work in schizophrenia, indicating possible shared risk factors. Observed dysconnectivity in remitted patients suggests a bipolar trait characteristic and may constitute a risk factor for phasic features of the disorder. PMID:22980587

    Bipolar disorder is a pernicious illness. Compared with the later-onset form, early onset bipolar disorder is associated with worse psychosocial outcomes, and is characterized by rapid cycling and increased risks of substance abuse and suicide attempts. Controlling mood episodes and preventing relapse in this group of pediatric patients requires careful treatment. Here, we review the effectiveness of aripiprazole for bipolar disorder in children and adolescents, with discussion of this drug’s unique pharmacological profile and various clinical study outcomes. Aripiprazole acts as a serotonin 5-HT2A receptor antagonist, as well as a partial agonist of the serotonin 5-HT1A and dopamine D2 receptors. It can be safely used in children and adolescents, as it is highly tolerated and shows lower rates of the side effects typically observed with other antipsychotic drugs, including sedation, weight gain, hyperprolactinemia, and extrapyramidal syndrome. The presently reviewed randomized controlled trials (RCTs) and non-RCTs generally reported aripiprazole to be effective and well-tolerated in children and adolescents with bipolar disorder. However, due to the limited number of RCTs, the present conclusions must be evaluated cautiously. Furthermore, aripiprazole cannot yet be considered a preferred treatment for children and adolescents with bipolar disorder, as there is not yet evidence that aripiprazole shows greater efficacy compared to other second-generation antipsychotics. Additional data are needed from future head-to-head comparison studies. PMID:25473324

    Background Although early interventions in individuals with bipolar disorder may reduce the associated personal and economic burden, the neurobiologic markers of enhanced risk are unknown. Methods Neuroimaging studies involving individuals at enhanced genetic risk for bipolar disorder (HR) were included in a systematic review. We then performed a region of interest (ROI) analysis and a whole-brain meta-analysis combined with a formal effect-sizes meta-analysis in a subset of studies. Results There were 37 studies included in our systematic review. The overall sample for the systematic review included 1258 controls and 996 HR individuals. No significant differences were detected between HR individuals and controls in the selected ROIs: striatum, amygdala, hippocampus, pituitary and frontal lobe. The HR group showed increased grey matter volume compared with patients with established bipolar disorder. The HR individuals showed increased neural response in the left superior frontal gyrus, medial frontal gyrus and left insula compared with controls, independent from the functional magnetic resonance imaging task used. There were no publication biases. Sensitivity analysis confirmed the robustness of these results. Limitations As the included studies were cross-sectional, it remains to be determined whether the observed neurofunctional and structural alterations represent risk factors that can be clinically used in preventive interventions for prodromal bipolar disorder. Conclusion Accumulating structural and functional imaging evidence supports the existence of neurobiologic trait abnormalities in individuals at genetic risk for bipolar disorder at various scales of investigation.

    Bipolar disorder is associated with significant deficits in the decoding of others' mental states in comparison to healthy participants. However, differences in theory of mind decoding ability among patients in manic, depressed, and euthymic phases of bipolar disorder is currently unknown. Fifty-nine patients with bipolar I or II disorder (13 manic, 25 depressed, 20 euthymic) completed the "Reading the Mind in the Eyes" Task (Eyes task) and the Animals Task developed to control for non-mentalistic response demands of the Eyes Task. Patients also completed self-report and clinician-rated measures of depression, mania, and anxiety symptoms. Patients in the manic phase were significantly less accurate than those in the depressed and euthymic phases at decoding mental states in the Eyes task, and this effect was strongest for eyes of a positive or neutral valence. Further Eyes task performance was negatively correlated with the symptoms of language/thought disorder, pressured speech, and disorganized thoughts and appearance. These effects held when controlling for accuracy on the Animals task, response times, and relevant demographic and clinical covariates. Results suggest that the state of mania, and particularly psychotic symptoms that may overlap with the schizophrenia spectrum, are most strongly related to social cognitive deficits in bipolar disorder.

    Depression, schizophrenia, and bipolar disorder are three of the four most burdensome problems in people aged under 25 years. In psychosis and depression, psychological interventions are effective, low-risk, and high-benefit approaches for patients at high risk of first-episode or early-onset disorders. We review the use of psychological interventions for early-stage bipolar disorder in patients aged 15-25 years. Because previous systematic reviews had struggled to identify information about this emerging sphere of research, we used evidence mapping to help us identify the extent, distribution, and methodological quality of evidence because the gold standard approaches were only slightly informative or appropriate. This strategy identified 29 studies in three target groups: ten studies in populations at high risk for bipolar disorder, five studies in patients with a first episode, and 14 studies in patients with early-onset bipolar disorder. Of the 20 completed studies, eight studies were randomised trials, but only two had sample sizes of more than 100 individuals. The main interventions used were family, cognitive behavioural, and interpersonal therapies. Only behavioural family therapies were tested across all of our three target groups. Although the available interventions were well adapted to the level of maturity and social environment of young people, few interventions target specific developmental psychological or physiological processes (eg, ruminative response style or delayed sleep phase), or offer detailed strategies for the management of substance use or physical health.

    Functional neuroimaging studies have implicated the involvement of the amygdala and ventrolateral prefrontal cortex (vlPFC) in the pathophysiology of bipolar disorder. Hyperactivity in the amygdala and hypoactivity in the vlPFC have been reported in manic bipolar patients scanned during the performance of an affective faces task. Whether this pattern of dysfunction persists during euthymia is unclear. Using functional magnetic resonance imaging (fMRI), 24 euthymic bipolar and 26 demographically matched healthy control subjects were scanned while performing an affective task paradigm involving the matching and labeling of emotional facial expressions. Neuroimaging results showed that, while amygdala activation did not differ significantly between groups, euthymic patients showed a significant decrease in activation of the right vlPFC (BA47) compared to healthy controls during emotion labeling. Additionally, significant decreases in activation of the right insula, putamen, thalamus and lingual gyrus were observed in euthymic bipolar relative to healthy control subjects during the emotion labeling condition. These data, taken in context with prior studies of bipolar mania using the same emotion recognition task, could suggest that amygdala dysfunction may be a state-related abnormality in bipolar disorder, whereas vlPFC dysfunction may represent a trait-related abnormality of the illness. Characterizing these patterns of activation is likely to help in understanding the neural changes related to the different mood states in bipolar disorder, as well as changes that represent more sustained abnormalities. Future studies that assess mood-state related changes in brain activation in longitudinal bipolar samples would be of interest. PMID:21854858

    Objective We explored the association between IBS and the development of bipolar disorder, and the risk factors for bipolar disorders in patients with IBS. Methods We identified patients who were newly diagnosed with IBS between 2000 and 2010 in the Taiwan National Health Insurance Research Database. We also identified a comparison matched cohort without IBS. The occurrence of new-onset bipolar disorder was evaluated in both cohorts. Results The IBS cohort consisted of 30,796 patients and the comparison cohort consisted of 30,796 matched patients without IBS. The incidence of bipolar disorder (incidence rate ratio, 2.63, 95% confidence interval (CI) 2.10–3.31, P < .001) was higher in the IBS patients than in the matched cohort. Multivariate matched regression models indicated that autoimmune diseases (HR 1.52, 95% CI 1.07–2.17, P = .020), and asthma (HR 1.45, 95% CI 1.08–1.95, P = .013) were independent risk factors for the development of bipolar disorder in the IBS patients. Conclusion IBS may increase the risk of developing subsequent bipolar disorder. Additional prospective studies are required to confirm these findings. PMID:25768120

    While deficits in metacognition have been observed in schizophrenia (SZ), it is less clear whether these are specific to the disorder. Accordingly, this study compared metacognitive abilities of patients with schizophrenia and bipolar disorder (BD) and examined the degree to which neurocognition contributed to metacognitive deficits in both groups. Participants were 30 patients with SZ and 30 with BD. Metacognitive capacity was measured using the Metacognition Assessment Scale Abbreviated (MAS-A). This scale comprises four domains: self-reflectivity, understanding others' minds, decentration and mastery. Verbal memory, executive functioning and symptoms were concurrently assessed. Group comparisons revealed that SZ patients had greater deficits in metacognitive self-reflectivity, which correctly classified 85.2% of patients with SZ in a logistic regression. Self-reflectivity and understanding others'minds were related to verbal memory and executive functioning in the SZ group, but not in the BD group. Furthermore, greater positive and general psychotic symptoms were associated with poorer metacognition in SZ. Results suggest SZ involves unique deficits in the ability to self-reflect and that these deficits may be uniquely linked with neurocognition.

    Cognitive deficits are observed in a variety of domains in patients with bipolar disorder (BD). These deficits are attributed to neurobiological, functional and structural brain factors, particularly in prefrontal cortex. Furthermore, cortical alterations in each phase (mania/hypomania, euthymia and depression) are also present. A growing basis of evidence supports aerobic exercise as an alternative treatment method for BD symptoms. Its benefits for physical health in healthy subjects and some psychiatric disorders are fairly established; however evidence directly addressed to BD is scant. Lack of methodological consistency, mainly related to exercise, makes it difficult accuracy and extrapolation of the results. Nevertheless, mechanisms related to BD physiopathology, such as hormonal and neurotransmitters alterations and mainly related to brain-derived neurotrophic factors (BDNF) can be explored. BDNF, specially, have a large influence on brain ability and its gene expression is highly responsive to aerobic exercise. Moreover, aerobic exercise trough BDNF may induce chronic stress suppression, commonly observed in patients with BD, and reduce deleterious effects caused by allostatic loads. Therefore, it is prudent to propose that aerobic exercise plays an important role in BD physiopathological mechanisms and it is a new way for the treatment for this and others psychiatric disorders.

    The author reviews the evolution of the concept of bipolar disorder as an ongoing process. Its roots can be found in the work of Araeteus of Capadocia, who assumed that melancholia and mania were two forms of the same disease. The modern understanding of bipolar disorder began in France, through the work of Falret (1851) and Baillarger (1854). The pivotal concepts of Emil Kraepelin changed the basis of psychiatric nosology, and Kraepelin's unitary concept of manic-depressive insanity was largely accepted. Kraepelin and Weigandt's ideas on mixed states were the cornerstone of this unitary concept. After Kraepelin, however, the ideas of Kleist and Leonhard, in Germany, as well as the work of Angst, Perris and Winokur, emphasized the distinction between unipolar and bipolar forms of depression. More recently, the emphasis has shifted again to the bipolar spectrum, which, in its mild forms, expanded to the limits of normal temperament. In concluding, the author summarizes the polemic aspects concerning the nosology of bipolar disorder and its boundaries in comparison with those of with schizophrenia, schizoaffective disorders and cycloid psychosis.

    The frequency of mania has not changed during the last century even with the development of new diagnostic criteria sets. More specifically, from the mid-1970s to 2000, the rate of mania (variably labeled major affective disorder–bipolar disorder and bipolar I disorder) was consistently identified in US and international studies as ranging from 0.4% to 1.6%. By the late 1990s to the 2000s, the prevalence reported by some researchers for bipolar disorders (I and II and others) was in the 5% to 7% and higher ranges. The purpose of this paper was to review explanations for this change and the potentially negative impacts on the field. PMID:22551790

    Individuals with bipolar disorder experience emotion regulation difficulties, even during remission, but are able to effectively employ emotion regulation strategies when instructed. We hypothesized that this puzzling discrepancy might be due to their maladaptive emotion regulation choices. To test this hypothesis, we used a previously validated paradigm (Sheppes, Scheibe, Suri, & Gross, 2011; Sheppes et al., 2014), and asked remitted individuals with bipolar I disorder (n = 25) and healthy individuals (n = 26) to view standardized positive and negative images of high and low intensity, and choose reappraisal or distraction to decrease their emotion intensity. Replicating and extending prior results, participants across both groups showed a pattern of choosing distraction more for high versus low intensity positive and negative images, but no between-groups differences were evident. These results suggest that emotion regulation choice patterns may be robust across samples, and add to growing evidence that several basic emotion regulation elements may remain intact in bipolar disorder.

    Social relationships and attachment are core developmental elements of human existence and survival that evolve over the lifetime of an individual. The internal and external factors that influence them include the presence of illness in the individual or in their immediate environment. The developmental aspects of attachment and social relationships have become increasingly of interest and relevance in light of early developmental epigenetic modification of gene expression patterns that may influence subsequent behavioral patterns and outcomes. This review examines extant literature on attachment and social relationships in bipolar cohorts. Despite many methodological challenges, the findings indicate that social relationships and capacity for attachment are significantly compromised in individuals with bipolar disorder compared to other mood disorders and normal controls. Though extant research is limited, research clearly points toward the importance of social relationships on the etiology, course, and consequences of bipolar disorder. We highlight a number of key considerations for future research.

    Objective Patients with bipolar disorder are prone to suicidal behavior, yet possible protective mechanisms are rarely studied. We investigated a possible protective role for moral or religious objections to suicide against suicidal ideation and attempts in depressed bipolar patients. Method A retrospective case control study of 149 depressed bipolar patients (DSM-III-R criteria) in a tertiary care university research clinic was conducted. Patients who reported religious affiliation were compared with 51 patients without religious affiliation in terms of sociodemographic and clinical characteristics and history of suicidal behavior. The primary outcome measure was the moral or religious objections to suicide subscale of the Reasons for Living Inventory (RFLI). Results Religiously affiliated patients had more children and more family-oriented social networks than nonaffiliated patients. As for clinical variables, religiously affiliated patients had fewer past suicide attempts, had fewer suicides in first-degree relatives, and were older at the time of first suicide attempt than unaffiliated patients. Furthermore, patients with religious affiliation had comparatively higher scores on the moral or religious objections to suicide subscale of the RFLI, lower lifetime aggression, and less comorbid alcohol and substance abuse and childhood abuse experience. After controlling for confounders, higher aggression scores (P = .001) and lower score on the moral or religious objections to suicide subscale of the RFLI (P < .001) were significantly associated with suicidal behavior in depressed bipolar patients. Moral or religious objections to suicide mediated the effects of religious affiliation on suicidal behavior in this sample. Conclusions Higher score on the moral or religious objections to suicide subscale of the RFLI is associated with fewer suicidal acts in depressed bipolar patients. The strength of this association was comparable to that of aggression scores and

    Lyme disease has been reported to be associated with various psychiatric presentations. Borreliaburgdorferi (Bb) can present with symptoms similar to schizophrenia and bipolar disorder. It has been suggested that inflammation incurred during the Bb infection leads to neurodegenerative changes that result in schizophrenia-like presentations. We report a case of a 41-year-old male with a past history of Bb infection who presents with psychosis. Later in the course of his hospitalization, he developed mood symptoms and was diagnosed with schizoaffective disorder, bipolar type. This case highlights the diagnosis and treatment of a patient with the unique presentation of schizoaffective disorder, bipolar type in the setting of previous Bb infection. PMID:25969618

    Bipolar disorder (BD) is a severe mental condition with neurodevelopmental features that clinically results in pathological fluctuations of mood. Whereas it was classically or traditionally considered as an adult-onset disorder, recent findings suggest that BD may occur very early in the life course, thus, determining what is now called Juvenile bipolar disorder (JBD). One of the reasons for which JBD has been so difficult to identify is that JBD primary symptoms vary much from the typical adulthood BD clinical expression. Euphoric mood is rare in JBD, while irritability mood, aggressive temper, mixed manic state onset, rapid cycling, anger outbursts and chronic course of symptoms are much more frequent. This specific clinical presentation makes JBD difficult to differentiate from other diagnoses related to pathological externalizing behaviours, including conduct disorder, oppositional provocative disorder, and attention deficit-hyperactivity disorder.

    Morbidity, mortality and economic consequences of bipolar affective disorder are very important to be evaluated because many of the costs entailed by this psychiatric disorder come from indirect costs due to inadequate diagnosis and treatment and from the characteristics of the affective symptoms itself. Psychotherapy focuses on diagnosis and the newest pharmacotherapy determines a decreasing of the morbidity of the disorder and also of its social and economic burden. However, more studies are necessary, with more heterogeneous patients, to find more predictors regarding the psychosocial consequences and to find more information about the prognosis of the bipolar disorder. In this context, in this paper we discuss the role of assisted resilience and the individualization of the therapy of bipolar affective disorder, especially that the resilience must be seen as a continuum and can be used anytime and in any situation, according to the theory of Geanellos. This idea is reflected in a case presentation of a patient with the diagnosis of bipolar disorder. PMID:26733744

    Depressive illnesses with subthreshold bipolar features are still misdiagnosed as unipolar. The goal of this study was to identify depressive disorder subtypes at risk for bipolarity. Four hundred ninety three major depressive patients were submitted to a cluster analysis on the basis of affective illness history and symptoms of the current episode. Seven clusters were identified which were regrouped into three age-at-onset subgroups; subgroups were further differentiated into subtypes according to predominant comorbidities. The latter were found to precede the occurrence of the related depressive disorder subtypes, decrease their age-at-onset, and increase their risk of belonging to the bipolar spectrum: the earlier the comorbidity, the higher the bipolar propensity was. This is likely to have implications for the diagnosis, natural history, as well as prophylaxis of bipolar disorders.

    An increasing amount of research has focused on insulin-like growth factor-1 (IGF-1) because of multiple neurotrophic effects, including neurogenesis, remyelination, and synaptogenesis. In addition, IGF-1 can mediate an antidepressant effect in patients with major affective disorder, and its levels in the cerebrospinal fluid have been found to vary with antidepressant treatment. Furthermore, it has been proven to crossover the blood-brain barrier, with a reciprocal feedback loop being the central effect. However, recent studies have reported inconclusive findings about the role of IGF-1 in major affective disorder. The aim of the current study was to conduct a thorough meta-analysis of changes in peripheral IGF-1 levels in patients with major depressive disorder (MDD) or bipolar disorder (BD). We conducted a thorough literature search and compared peripheral IGF-1 levels in patients with MDD or BD and in healthy controls, and investigated clinical variables through meta-regression. Electronic research was conducted through platform of PubMed. We used inclusion criteria as clinical trials discussing comparisons of peripheral IGF-1 protein levels in patients with MDD or BD and those in healthy controls. We analyzed the cases from 9 studies with the random-effect model. The main finding was that peripheral IGF-1 levels in the patients were significantly higher than in the healthy controls (P < 0.001), with a significant inverse association with duration of illness (P = 0.03). In meta-analysis comparing peripheral IGF-1 levels in patients with BD or MDD before and after treatment, there was no significant change in peripheral IGF-1 levels after treatment (P = 0.092). The small numbers of studies and lack of correlation data with growth hormone in current studies are the main limitations of this meta-analysis. Our results indicated that peripheral IGF-1 levels may not be an indicator of disease severity, but may be a disease trait marker or an indicator of

Our results indicated that peripheral IGF-1 levels may not be an indicator of disease severity, but may be a disease trait marker or an indicator of

    Palmar and finger dermatoglyphics are formed between the 10th and the 17th weeks of gestation and their morphology can be influenced by genetic or environmental factors, interfering with normal intrauterine development. As both the skin and the brain develop from the same embryonal ectoderm, dermatoglyphic alterations may be informative for early abnormal neurodevelopmental processes in the brain. We investigated whether dermatoglyphic alterations are related to structural brain abnormalities in bipolar disorder and to what extent they are of a genetic and of an environmental origin. Dermatoglyphics and volumetric data from structural MRI were obtained in 53 twin pairs concordant or discordant for bipolar disorder and 51 healthy matched control twin pairs. Structural equation modeling was used. Bipolar disorder was significantly positively associated with palmar a-b ridge count (ABRC), indicating higher ABRC in bipolar patients (rph=.17 (CI .04-.30)). Common genes appear to be involved because the genetic correlation with ABRC was significant (rph-A=.21 (CI .05-.36). Irrespective of disease, ABRC showed a genetically mediated association with brain volume, indicated by a significant genetic correlation rph-A of respectively -.36 (CI -.52 to -.22) for total brain, -.34 (CI -.51 to -.16) total cortical volume, -.27 (CI -.43 to -.08) cortical gray matter and -.23 (CI -.41 to -.04) cortical white matter. In conclusion, a genetically determined abnormal development of the foetal ectoderm between the 10th and 15th week of gestation appears related to smaller brain volumes in (subjects at risk for) bipolar disorder.

    The relationship between the risks for face-emotion labeling deficits and bipolar disorder (BD) among youths is examined. Findings show that youths at risk for BD did not show specific face-emotion recognition deficits. The need to provide more intense emotional information for face-emotion labeling of patients and at-risk youths is also discussed.

    As with physical conditions, bipolar disorder is likely to be impacted by diet and nutrition. Patients with bipolar disorder have been noted to have relatively unhealthy diets, which may in part be the reason they also have an elevated risk of metabolic syndrome and obesity. An improvement in the quality of the diet should improve a bipolar patient's overall health risk profile, but it may also improve their psychiatric outcomes. New insights into biological dysfunctions that may be present in bipolar disorder have presented new theoretic frameworks for understanding the relationship between diet and bipolar disorder.

  9. Unipolar depression with racing thoughts: a bipolar spectrum disorder?

    Major depressive disorder (MDD) with racing/crowded thoughts is understudied. Kraepelin classified 'depression with flight of ideas' in the mixed states of his manic-depressive insanity. The aim of the study was to test whether MDD with racing/crowded thoughts was close to bipolar disorders. Consecutive 379 bipolar-II disorder (BP-II) and 271 MDD depressed outpatients were interviewed using the Structured Clinical Interview for DSM-IV, the Hypomania Interview Guide, and the Family History Screen, by a senior psychiatrist in a private practice. Intra-depression hypomanic symptoms were systematically assessed. Mixed depression was defined as a major depressive episode (MDE) plus three or more intra-MDE hypomanic symptoms. MDD with racing/crowded thoughts was compared to MDD without racing/crowded thoughts on classic bipolar validators (young onset age, many recurrences, atypical and mixed depression, bipolar family history). Frequency of MDD with racing/crowded thoughts was 56.4%. MDD with racing/crowded thoughts, versus MDD without racing/crowded thoughts, had significantly lower age at onset, more MDE severity, more psychotic, melancholic, atypical, and mixed depressions, and more bipolar family history. Of the intra-MDE hypomanic symptoms, irritability, psychomotor agitation and distractibility were significantly more common in MDD with racing/crowded thoughts. Compared to BP-II on bipolar validators, validators were less common in MDD with racing/crowded thoughts. MDD with racing/crowded thoughts seemed to be a severe variant of MDD. MDD with racing/crowded thoughts versus MDD without racing/crowded thoughts, and versus BP-II, had significant differences on bipolar validators, suggesting that it may lie along a continuum linking MDD without racing/crowded thoughts and BP-II.

    Considerable evidence demonstrates that neuropsychological deficits are prevalent in bipolar disorder during both acute episodes and euthymia. However, it is less clear whether these cognitive disturbances are state- or trait-related. We here present the first longitudinal study employing a within-subject pre- and post-testing examining acutely admitted bipolar patients (BP) in depression or mania and during euthymia, aiming to identify cognitive performance from acute illness to remission. Cognitive performance was measured during acute episodes and repeated after at least 3 months of remission. To do so, 55 BP (35 depressed, 20 hypo-/manic) and 55 healthy controls (HC) were tested with a neuropsychological test battery (attention, working memory, verbal memory, executive functioning). The results showed global impairments in acutely ill BP compared to HC: depressed patients showed a characteristic psychomotor slowing, while manic patients had severe deficits in executive functioning. Twenty-nine remitted BP could be measured in the follow-up (dropout rate 48 %), whose cognitive functions partially recovered, whereas working memory and verbal memory were still impaired. However, we found that subthreshold depressive symptoms and persisting sleep disturbances in euthymic BP were associated with reduced speed, deficits in attention and verbal memory, while working memory was correlated with psychotic symptoms (lifetime). This result indicates working memory as trait related for a subgroup of BP with psychotic symptoms. In contrast, attention and verbal memory are negatively influenced by state factors like residual symptoms, which should be more considered as possible confounders in the search of cognitive endophenotypes in remitted BP.

    Despite ongoing controversy, the view that pediatric mania is rare or nonexistent has been increasingly challenged not only by case reports, but also by systematic research. This research strongly suggests that pediatric mania may not be rare but that it may be difficult to diagnose. Since children with mania are likely to become adults with bipolar disorder, the recognition and characterization of childhood-onset mania may help identify a meaningful developmental subtype of bipolar disorder worthy of further investigation. The major difficulties that complicate the diagnosis of pediatric mania include: 1) its pattern of comorbidity may be unique by adult standards, especially its overlap with attention-deficit/hyperactivity disorder, aggression, and conduct disorder; 2) its overlap with substance use disorders; 3) its association with trauma and adversity; and 4) its response to treatment is atypical by adult standards.

    About half of all bipolar patients have an alcohol abuse problem at some point of their lifetime. However, only one randomized, controlled trial of pharmacotherapy (valproate) in this patient population was published as of 2006. Therefore, we reviewed clinical trials in this indication of the last four years (using mood stabilizers, atypical antipsychotics, and other drugs). Priority was given to randomized trials, comparing drugs with placebo or active comparator. Published studies were found through systematic database search (PubMed, Scirus, EMBASE, Cochrane Library, Science Direct). In these last four years, the only randomized, clinically relevant study in bipolar patients with comorbid alcoholism is that of Brown and colleagues (2008) showing that quetiapine therapy decreased depressive symptoms in the early weeks of use, without modifying alcohol use. Several other open-label trials have been generally positive and support the efficacy and tolerability of agents from different classes in this patient population. Valproate efficacy to reduce excessive alcohol consumption in bipolar patients was confirmed and new controlled studies revealed its therapeutic benefit to prevent relapse in newly abstinent alcoholics and to improve alcohol hallucinosis. Topiramate deserves to be investigated in bipolar patients with comorbid alcoholism since this compound effectively improves physical health and quality of life of alcohol-dependent individuals. In conclusion, randomized, controlled research is still needed to provide guidelines for possible use of valproate and other agents in patients with a dual diagnosis of bipolar disorder and substance abuse or dependence.

It was adopted a mixed criterion for its preparation: all the recent data of the evidence medicine based published until now were discussed and were balanced with the knowledge acquired from clinical experience of the local experts on the bipolar field. It presents general recommendations and suggested therapeutic sequences for the phase of maintenance, the manic/hypomanic or mixed episode and the depressive episode. These have been divided according to the classification in type I and II; with or without rapid cycling. Since the group of experts identified the delay and miss-diagnoses like the most important barrier for a suitable treatment enclosed a series of recommendations for differential diagnosis of bipolar disorders.

    Genetic risk prediction has several potential applications in medical research and clinical practice and could be used, for example, to stratify a heterogeneous population of patients by their predicted genetic risk. However, for polygenic traits, such as psychiatric disorders, the accuracy of risk prediction is low. Here we use a multivariate linear mixed model and apply multi-trait genomic best linear unbiased prediction for genetic risk prediction. This method exploits correlations between disorders and simultaneously evaluates individual risk for each disorder. We show that the multivariate approach significantly increases the prediction accuracy for schizophrenia, bipolar disorder, and major depressive disorder in the discovery as well as in independent validation datasets. By grouping SNPs based on genome annotation and fitting multiple random effects, we show that the prediction accuracy could be further improved. The gain in prediction accuracy of the multivariate approach is equivalent to an increase in sample size of 34% for schizophrenia, 68% for bipolar disorder, and 76% for major depressive disorders using single trait models. Because our approach can be readily applied to any number of GWAS datasets of correlated traits, it is a flexible and powerful tool to maximize prediction accuracy. With current sample size, risk predictors are not useful in a clinical setting but already are a valuable research tool, for example in experimental designs comparing cases with high and low polygenic risk.

    2013-01-01

    Background Individuals with serious mental disorders experience poor physical health, especially increased rates of cardiometabolic morbidity and premature morbidity. Recent evidence suggests that individuals with schizophrenia have numerous comorbid physical conditions that may be under-recorded and undertreated, but to date very few studies have explored this issue for bipolar disorder. Methods We conducted a cross-sectional analysis of a dataset of 1,751,841 registered patients within 314 primary care practices in Scotland, UK. Bipolar disorder was identified using Read Codes recorded within electronic medical records. Data on 32 common chronic physical conditions were also assessed. Potential prescribing inequalities were evaluated by analysing prescribing data for coronary heart disease (CHD) and hypertension. Results Compared to controls, individuals with bipolar disorder were significantly less likely to have no recorded physical conditions (OR 0.59, 95% CI 0.54 to 0.63) and significantly more likely to have one physical condition (OR 1.27, 95% CI 1.16 to 1.39), two physical conditions (OR 1.45, 95% CI 1.30 to 1.62) and three or more physical conditions (OR 1.44, 95% CI 1.30 to 1.64). People with bipolar disorder also had higher rates of thyroid disorders, chronic kidney disease, chronic pain, chronic obstructive airways disease and diabetes but, surprisingly, lower recorded rates of hypertension and atrial fibrillation. People with bipolar disorder and comorbid CHD or hypertension were significantly more likely to be prescribed no antihypertensive or cholesterol-lowering medications compared to controls, and bipolar individuals with CHD or hypertension were significantly less likely to be on two or more antihypertensive agents. Conclusions Individuals with bipolar disorder are similar to individuals with schizophrenia in having a wide range of comorbid and multiple physical health conditions. They are also less likely than controls to have a primary

    Marijuana is the most widely used illicit substance in those diagnosed with bipolar I disorder. However, there is conflicting evidence as to whether marijuana may alleviate or exacerbate mood symptomatology. As bipolar disorder and marijuana use are individually associated with cognitive impairment, it also remains unclear whether there is an additive effect on cognition when bipolar patients use marijuana. The current study aimed to determine the impact of marijuana on mood in bipolar patients and to examine whether marijuana confers an additional negative impact on cognitive function. Twelve patients with bipolar disorder who smoke marijuana (MJBP), 18 bipolar patients who do not smoke (BP), 23 marijuana smokers without other Axis 1 pathology (MJ), and 21 healthy controls (HC) completed a neuropsychological battery. Further, using ecological momentary assessment, participants rated their mood three times daily as well as after each instance of marijuana use over a four-week period. Results revealed that although the MJ, BP, and MJBP groups each exhibited some degree of cognitive impairment relative to HCs, no significant differences between the BP and MJBP groups were apparent, providing no evidence of an additive negative impact of BPD and MJ use on cognition. Additionally, ecological momentary assessment analyses indicated alleviation of mood symptoms in the MJBP group after marijuana use; MJBP participants experienced a substantial decrease in a composite measure of mood symptoms. Findings suggest that for some bipolar patients, marijuana may result in partial alleviation of clinical symptoms. Moreover, this improvement is not at the expense of additional cognitive impairment.
