    1999-02-01

    Autism is a developmental disorder affecting social relationships, communication and flexibility of thought. These three basic aspects of autism may present in many different forms and degrees. Therefore autism should be considered to be a spectrum of autistic disorders rather than a single strictly defined condition. The spectrum of autistic disorders extends from intelligent individuals with acceptable social integration, to severely retarded patients with scarcely any social interaction. Language is almost always affected either in its formal aspects or in its usage. Autistic linguistic disorders form a specific language disorder (developmental dysphasia) and a pragmatic disorder linked both to the primary language problem and to the social cognitive deficit. We discuss the different linguistic syndromes observed in autistic patients with special emphasis on the semantic-pragmatic disorder. PMID:10778500

    PubMed

    Jones, G S

    2000-01-01

    Recognition of the autistic spectrum disorders is becoming more widespread amongst basic scientists, clinicians, and the general population. The term does not imply anything about pathology or aetiology, although it has proved to be a useful concept clinically. From Kanner's classical autism the concept has widened in scope to include milder and more subtle impairments. From a clinical perspective, there are many alternative diagnoses in an individual with autistic-like symptoms, and thorough investigation is necessary to exclude these. PMID:10970710

    Vernon, McCay; Rhodes, Anthony

    2009-01-01

    An orientation to autistic spectrum disorders (ASD), also known as autism, is provided, and the specific syndrome of autism and deafness is addressed. The two conditions have in common a major problem: communication. Case histories are provided, the development of treatment for autism is discussed, and the separate disorders that make up ASD are defined. Important medical conditions often present in ASD are named, and their roles in treatment and diagnosis are described. Because autism is generally regarded as increasing in prevalence, some say to epidemic proportions, there is an increase in children who are both deaf and autistic. The resulting pressure on day and residential school programs for the Deaf to accept and educate these difficult, multiply disabled children is increasing. The parents of autistic children are a sophisticated, politically active group who are demanding services through legal and legislative means, among others. PMID:19569300

    Baghdadli, A; Gonnier, V; Aussilloux, C

    2002-01-01

    Autism is an early developmental disorder. It leads to severe and durable disturbances. Given this problem, no treatment can be excluded a priori. Thus, many approaches are used to deal with autistic disorders. In France, pharmacological treatments are, for instance, largely and mostly used in adults. In the USA, these treatments concern 50% of persons with autism of any age. Nevertheless, they are rarely based on controlled studies. At the present, however, prescriptions and expected effects appear to be hard to localize. Furthermore, only few controlled studies validate their use. Aim - We offer a review of studies about medical treatments used in adolescents and adults with autism. They are classified in 3 categories: the first (category I) includes drugs used for their neurochemical effects focusing on autistic signs. The second (category II) covers drugs used for treatment of behavioural disorders frequently associated with autism. The third (category III) corresponds to a wide range of drugs or vitamins for wich only few case studies exist reporting irregular positive effects. The main hypothesis of this review is that autism involves a dysfunction of the neuromediation systems. This hypothesis opens new perspectives in the research of medical treatments in autism by focusing on molecules, which are supposed to have an effect on neuromediation systems. Method - Our review is based on studies, which have been published during the past twenty years. For many studies, data are limited to adolescents and adults. So we expanded our review to data available in children. The data bases that we have used are medline and psyclit. Keywords have been chosen according to: pharmacological considerations (psychotropic, psychoactive drugs, psychopharmacology) and clinical symptoms (autism, automutilations, aggressive behavior, and hyperactivity). Hypothesis of a dysfunction in the neuromediation systems in autism - Many studies exist about biochemical abnormalities in

    OBJECTIVE: To review existing data on early signs of autistic spectrum disorders (ASD) and on how these disorders can be distinguished from other atypical patterns of development, and to describe a developmental surveillance approach that family physicians can use to ensure that children with these diagnoses are detected as early as possible. QUALITY OF EVIDENCE: MEDLINE was searched from January 1966 to July 2000 using the MeSH terms autistic disorder/diagnosis AND diagnosis, differential AND (infant OR child, preschool). Articles were selected based on relevance to developmental surveillance in primary care and on experimental design, with emphasis on prospective studies with systematic measurement procedures using up-to-date diagnostic criteria. MAIN MESSAGE: Autistic spectrum disorders are characterized by impairments in social interaction and verbal and nonverbal communication, and by preferences for repetitive interests and behaviours. Early signs that distinguish ASD from other atypical patterns of development include poor use of eye gaze, lack of gestures to direct other people's attention (particularly to show things of interest), diminished social responsiveness, and lack of age-appropriate play with toys (especially imaginative use of toys). Careful attention to parents' concerns and specific inquiry into and observation of how children interact, communicate, and play will help ensure that early signs are detected during regular health maintenance visits. CONCLUSION: Family physicians have an important role in early identification of children with ASD. Early diagnosis of these disorders is essential to ensure timely access to interventions known to improve outcomes for these children. PMID:11723598

    Aresti-Bartolome, Nuria; Garcia-Zapirain, Begonya

    2014-01-01

    This study analyzes the technologies most widely used to work on areas affected by the Autistic Spectrum Disorder (ASD). Technologies can focus on the strengths and weaknesses of this disorder as they make it possible to create controlled environments, reducing the anxiety produced by real social situations. Extensive research has proven the efficiency of technologies as support tools for therapy and their acceptation by ASD sufferers and the people who are with them on a daily basis. This article is organized by the types of systems developed: virtual reality applications, telehealth systems, social robots and dedicated applications, all of which are classified by the areas they center on: communication, social learning and imitation skills and other ASD-associated conditions. 40.5% of the research conducted is found to be focused on communication as opposed to 37.8% focused on learning and social imitation skills and 21.6% which underlines problems associated with this disorder. Although most of the studies reveal how useful these tools are in therapy, they are generic tools for ASD sufferers in general, which means there is a lack of personalised tools to meet each person’s needs.

    A structured search and identification of themes within the literature regarding the use of Social Stories to decrease disruptive behaviour in children with autistic spectrum disorders is presented. The examination of seven studies showed that the Social Story intervention was successful for the majority of the participants, although the level of success was variable. Overall, Social Stories appear to be an acceptable intervention for use in the classroom, however unplanned verbal prompting by teachers, in some studies, reduced confidence in the effectiveness of Social Stories when used in isolation. An increasing body of literature has indicated that Social Stories are an effective intervention for children diagnosed with autistic spectrum disorders, however very few studies have addressed the efficacy of Social Stories when used with children with other disabilities.

  3. The savant syndrome and autistic disorder.

    PubMed

    Treffert, D A

    1999-12-01

    Savant syndrome, characterized by remarkable islands of mental ability in otherwise mentally handicapped persons, may occur in autistic as well as nonautistic individuals. Overall, approximately 10% of autistic persons exhibit savant abilities; roughly 50% of those with savant syndrome have autism, and the remaining 50% have other forms of developmental disability. Most commonly, savant syndrome takes the form of extraordinary musical abilities, but may also include calendar-calculation, artistic, mathematical, spatial, mechanical, and memory skills. While savant syndrome was first described more than a century ago, only recently have researchers begun to employ a more uniform nomenclature and more standardized testing in an effort to compare the abilities of savants with those of normal persons. Males show signs of savant syndrome approximately four times more often than females. Along with imaging study findings, this fact suggests the presence of a developmental disorder involving left-brain damage with right-brain compensation. PMID:18311109

  7. Autistic spectrum disorders as functional disconnection syndrome.

    PubMed

    Melillo, Robert; Leisman, Gerry

    2009-01-01

    We outline the basis of how functional disconnection with reduced activity and coherence in the right hemisphere would explain all of the symptoms of autistic spectrum disorder as well as the observed increases in sympathetic activation. If the problem of autistic spectrum disorder is primarily one of desynchronization and ineffective interhemispheric communication, then the best way to address the symptoms is to improve coordination between areas of the brain. To do that the best approach would include multimodal therapeusis that would include a combination of somatosensory, cognitive, behavioral, and biochemical interventions all directed at improving overall health, reducing inflammation and increasing right hemisphere activity to the level that it becomes temporally coherent with the left hemisphere. We hypothesize that the unilateral increased hemispheric stimulation has the effect of increasing the temporal oscillations within the thalamocortical pathways bringing it closer to the oscillation rate of the adequately functioning hemisphere. We propose that increasing the baseline oscillation speed of one entire hemisphere will enhance the coordination and coherence between the two hemispheres allowing for enhanced motor and cognitive binding.

  8. Memory in autistic spectrum disorder.

    PubMed

    Boucher, Jill; Mayes, Andrew; Bigham, Sally

    2012-05-01

    Behavioral evidence concerning memory in forms of high-functioning autism (HFA) and in moderately low-functioning autism (M-LFA) is reviewed and compared. Findings on M-LFA are sparse. However, it is provisionally concluded that memory profiles in HFA and M-LFA (relative to ability-matched controls) are similar but that declarative memory impairments are more extensive in M-LFA than in HFA. Specifically, both groups have diminished memory for emotion- or person-related stimuli. Regarding memory for nonsocial stimuli, both groups probably have mental-age-appropriate nondeclarative memory, and within declarative memory, both groups have mental-age-appropriate immediate free recall of within-span or supraspan lists of unrelated items, as well as cued recall and paired associate learning. By contrast, recognition is largely unimpaired in HFA but moderately impaired in M-LFA, and free recall of meaningful or structured stimuli is moderately impaired in HFA but more severely impaired in M-LFA. Theoretical explanations of data on declarative memory in HFA identify problems in the integrative processing, or the consolidation and storage, of complex stimuli or a specific problem of recollection. Proposed neural substrates include the following: disconnectivity of primary sensory and association areas; dysfunctions of medial prefrontal cortex, hippocampus, or posterior parietal lobe; or combinations of these associated with neural disconnectivity. Hypothetically, perirhinal dysfunction might explain the more extensive declarative memory impairments in M-LFA. Foreseeable consequences of uneven memory abilities in HFA and M-LFA are outlined, including possible effects on language and learning in M-LFA. Finally, priorities for future research are identified, highlighting the urgent need for research on memory in lower functioning individuals. PMID:22409507

    To address a possible environmental contribution to autism, we carried out a retrospective study on urinary porphyrin levels, a biomarker of environmental toxicity, in 269 children with neurodevelopmental and related disorders referred to a Paris clinic (2002-2004), including 106 with autistic disorder. Urinary porphyrin levels determined by high-performance liquid chromatography were compared between diagnostic groups including internal and external control groups. Coproporphyrin levels were elevated in children with autistic disorder relative to control groups. Elevation was maintained on normalization for age or to a control heme pathway metabolite (uroporphyrin) in the same samples. The elevation was significant (P < 0.001). Porphyrin levels were unchanged in Asperger's disorder, distinguishing it from autistic disorder. The atypical molecule precoproporphyrin, a specific indicator of heavy metal toxicity, was also elevated in autistic disorder (P < 0.001) but not significantly in Asperger's. A subgroup with autistic disorder was treated with oral dimercaptosuccinic acid (DMSA) with a view to heavy metal removal. Following DMSA there was a significant (P = 0.002) drop in urinary porphyrin excretion. These data implicate environmental toxicity in childhood autistic disorder.

    Individuals with autistic spectrum disorders (ASDs) often experience, describe and exhibit unusual patterns of sensation and attention. These anomalies have been hypothesized to result from overarousal and consequent overfocused attention. Parents of individuals with ASD rated items in three domains, "sensory overreactivity", "sensory…

    Background It has been suggested that peptides from gluten and casein may have a role in the origins of autism and that the physiology and psychology of autism might be explained by excessive opioid activity linked to these peptides. Research has reported abnormal levels of peptides in the urine and cerebrospinal fluid of people with autism. Objectives To determine the efficacy of gluten and/or casein free diets as an intervention to improve behaviour, cognitive and social functioning in individuals with autism. Search methods The following electronic databases were searched: CENTRAL(The Cochrane Library Issue 2, 2007), MEDLINE (1966 to April 2007), PsycINFO (1971 to April 2007), EMBASE (1974 to April 2007), CINAHL (1982 to April 2007), ERIC (1965 to 2007), LILACS (1982 to April 2007), and the National Research register 2007 (Issue1). Review bibliographies were also examined to identify potential trials. Selection criteria All randomised controlled trials (RCT) involving programmes which eliminated gluten, casein or both gluten and casein from the diets of individuals diagnosed with an autistic spectrum disorder. Data collection and analysis Abstracts of studies identified in searches of electronic databases were assessed to determine inclusion by two independent authors The included trials did not share common outcome measures and therefore no meta-analysis was possible. Data are presented in narrative form. Main results Two small RCTs were identified (n = 35). No meta-analysis was possible. There were only three significant treatment effects in favour of the diet intervention: overall autistic traits, mean difference (MD) = −5.60 (95% CI −9.02 to −2.18), z = 3.21, p=0.001 (Knivsberg 2002) ; social isolation, MD = −3.20 (95% CI −5.20 to 1.20), z = 3.14, p = 0.002) and overall ability to communicate and interact, MD = 1.70 (95% CI 0.50 to 2.90), z = 2.77, p = 0.006) (Knivsberg 2003). In addition three outcomes showed no significant difference between the

    The epidemiology of the autistic spectrum disorders is changing. A clear increase in prevalence has been noted during the past 2 decades. What is less clear is the cause for this increase. Multiple factors appear to be responsible. The preponderance of evidence suggests most of the rise in incidence and prevalence is related to changes in diagnostic criteria and greater awareness on the part of both professionals and parents. Proposed theories of causation, which also seek to explain the increase in prevalence, have not been substantiated. Further research is needed to better determine the incidence and prevalence of these disorders and their etiologic factors. PMID:14606220

    2011-01-01

    Pervasive Developmental Disorders (PPD) refers to the group of disorders characterised by delayed or inappropriate development of multiple basic functions including socialisation, communication, behaviour and cognitive functioning. The term,,autistic spectrum disorders" was established as a result of the magnitude of the intensity of symptoms and their proportions observed in all types of pervasive developmental disorders. Asperger's Syndrome (AS) remains the most controversial diagnosis in terms of its place within autism spectrum disorders. AS if often described as an equivalent of High Functioning Autism (HFA) or as a separate spectrum-related disorder with unique diagnostic criteria. Another important issue is the relationship between AS and speech disorders. Although it is relatively easy to draw a line between children with classical autism and speech disorders, the clear cut frontiers between them still remain to be found. The main distinguishing feature is the lack of stereotypic interests and unimpaired social interaction observed in children with speech disorders, such as semantic-pragmatic disorder. PMID:22220491

    A partial trisomy 16p was identified in a 14-year-old male adolescent with autistic disorder. He additionally showed complex motor and vocal phenomena, including some simple tics which had first appeared in childhood. Whereas these simple tics were of subclinical significance, an additional diagnosis of Tourette`s syndrome (TS) appears justified. The case report illustrates the diagnostic difficulties in assessing psychiatric symptomatology associated with both disorders, especially complex motor and vocal phenomena. The cytogenetic finding is discussed critically in the light of other chromosome abnormalities reported in both TS and autistic disorder. Chromosome 16p should be considered as a candidate region especially for autistic disorder. 21 refs.

    Prader-Willi syndrome (PWS) is a neuro-genetic disorder caused by the absence/loss of expression of one or more paternally expressed genes on chromosome 15 (q11-13). In this study, a comparative analysis of intelligence level and autistic traits was conducted between children with PWS (n = 30; 18 males, 12 females; age = 10.6 ± 2.8 years) and those with Asperger disorder (AD; n = 31; 24 males, 7 females; age = 10.5 ± 3.1 years). The children were compared by age group: lower elementary school age (6-8 years), upper elementary school age (9-12 years), and middle school age (13-15 years). As results, the intelligence levels of children with PWS were significantly lower than those with AD across all age groups. Autistic traits, assessed using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), revealed that among elementary school age children, those with PWS had less prominent autistic traits than those with AD, however, among middle school age children, those with PWS and AD showed similar prominence. An analysis of the PARS subscale scores by age group showed that while the profiles of autistic traits for children with PWS differed from those of children with AD at elementary school age, the profiles showed no significant differences between the groups at middle school age. The findings suggest that autistic traits in PWS become gradually more prominent with increasing of age and that these autistic traits differ in their fundamental nature from those observed in AD.

    ABSTRACT The objective of this study was to assess the oral hygiene practices, dietary pattern, dental caries status and needs of institutionalized autistic children. The sample consisted of 35 children (28 males and 7 females) in the age group of 5 to 10 years from two institutions in Maharashtra, India. The parents of the children were interviewed regarding oral hygiene practices of their respective ward and instructed to maintain a 4-day diet chart for their children. A clinical examination was conducted using WHO dentition status and treatment needs index and a simplified oral hygiene index for ages 4 to 6 years and 7 to 10 years (deciduous and mixed dentition) was used to assess the oral hygiene. The results of diet chart analysis according to Nizel AE and Papas AS score showed the ‘at meal’ sugar exposure close to nil, while the ‘in between’ meal sugar exposure was observed to be more than three times per day among maximum children. The oral hygiene status was poor with abundance of soft debris and fair calculus accumulation. The mean caries experience (deft) in these children was 6.4. The present study provided baseline data which has been used for planning a comprehensive oral health care program. How to cite this article: Chadha GM, Kakodkar P, Chaugule V, Nimbalkar V.

    Infantile autism is a pervasive developmental disorder characterized by disturbances concerning not only the areas of socialization and communication ("aloneness") but also the ability to modify and change behavior ("need for sameness"). In most recent studies, various abnormal and deviant cognitive activities, such as the ability to regulate one's behavior, were considered as accounting for these signs. In this report, we examined the regulation of cognitive activity, from a developmental perspective in comparing autistic with mentally retarded children matched in a pairwise manner by global, verbal, and nonverbal developmental ages. All children were tested with tasks adapted from the Object Permanence Test which corresponds to Piaget's sensorimotor development Stages IV to VI. Results showed that autistic children had a pervasive difficulty in maintenance set, made more perseverative errors when the abstraction degree of task was higher, and were more variable in their behavioral strategies. Discussion is focused on the interests and limits of these tasks for the examination of regulation activity from diagnostic and developmental perspectives. Finally, interpretations about recent neuropsychological and neurophysiological works, and additional interdisciplinary studies are suggested. PMID:7559291

    The aim of this study was to evaluate the short-term efficacy and safety of lurasidone in treating irritability associated with autistic disorder. In this multicenter trial, outpatients age 6-17 years who met DSM-IV-TR criteria for autistic disorder, and who demonstrated irritability, agitation, and/or self-injurious behaviors were randomized to 6 weeks of double-blind treatment with lurasidone 20 mg/day (N = 50), 60 mg/day (N = 49), or placebo (N = 51). Efficacy measures included the Aberrant Behavior Checklist Irritability subscale (ABC-I, the primary endpoint) and the Clinical Global Impressions, Improvement (CGI-I) scale, and were analyzed using a likelihood-based mixed model for repeated measures. Least squares (LS) mean (standard error [SE]) improvement from baseline to Week 6 in the ABC-I was not significantly different for lurasidone 20 mg/day (-8.8 [1.5]) and lurasidone 60 mg/day (-9.4 [1.4]) versus placebo (-7.5 [1.5]; p = 0.55 and 0.36, respectively). CGI-I scores showed significantly greater LS mean [SE] improvement at Week 6 for lurasidone 20 mg/day versus placebo (2.8 [0.2] vs. 3.4 [0.2]; p = 0.035) but not for lurasidone 60 mg/day (3.1 [0.2]; p = 0.27). Discontinuation rates due to adverse events were: lurasidone 20 mg/day, 4.1 %; 60 mg/day, 3.9 %; and placebo, 8.2 %. Adverse events with an incidence ≥10 % (lurasidone combined, placebo) included vomiting (18.0, 4.1 %) and somnolence (12.0, 4.1 %). Modest changes were observed in weight and selected metabolic parameters. In this study, once-daily, fixed doses of 20 and 60 mg/day of lurasidone were not demonstrated to be efficacious compared to placebo for the short-term treatment of children and adolescents with moderate-to-severe irritability associated with autistic disorder.

    Background. User feedback is now an integral part of both clinical governance and service development, and it also provides a key route to engaging parents and children. Autistic spectrum disorders (ASDs) can impact on all members of a family, and close working between parents and professionals is essential. Aim. To explore parental satisfaction rates and identify areas in need of improvement. Method. A postal survey was completed by parents whose children had been diagnosed with an ASD in the past 18 months in a Manchester Child and Adolescent Mental Health Service. The National Autism Plan for Children was used as a gold standard. Results. Parents were particularly satisfied with the way team members dealt with them and their children during appointments. However, the standard of written information provided about the condition, diagnosis, and support available could be improved. The findings show the benefits of receiving a diagnosis in the recommended timeframe. Discussion. We discuss ways of effectively using scarce resources. PMID:22295189

    Autism spectrum disorder often co-occurs with other psychiatric disorders. Although a high prevalence of autistic-like traits/symptoms has been identified in the pediatric psychiatric population of normal intelligence, there are no reports from adult psychiatric population. This study examined whether there is a greater prevalence of autistic-like traits/symptoms in patients with adult-onset psychiatric disorders such as major depressive disorder (MDD), bipolar disorder, or schizophrenia, and whether such an association is independent of symptom severity. The subjects were 290 adults of normal intelligence between 25 and 59 years of age (MDD, n=125; bipolar disorder, n=56; schizophrenia, n=44; healthy controls, n=65). Autistic-like traits/symptoms were measured using the Social Responsiveness Scale for Adults. Symptom severity was measured using the Positive and Negative Symptoms Scale, the Hamilton Depression Rating Scale, and/or the Young Mania Rating Scale. Almost half of the clinical subjects, except those with remitted MDD, exhibited autistic-like traits/symptoms at levels typical for sub-threshold or threshold autism spectrum disorder. Furthermore, the proportion of psychiatric patients that demonstrated high autistic-like traits/symptoms was significantly greater than that of healthy controls, and not different between that of remitted or unremitted subjects with bipolar disorder or schizophrenia. On the other hand, remitted subjects with MDD did not differ from healthy controls with regard to the prevalence or degree of high autistic-like traits/symptoms. A substantial proportion of adults with bipolar disorder and schizophrenia showed high autistic-like traits/symptoms independent of symptom severity, suggesting a shared pathophysiology among autism spectrum disorder and these psychiatric disorders. Conversely, autistic-like traits among subjects with MDD were associated with the depressive symptom severity. These findings suggest the importance of

    A constant challenge for Quality of Life (QoL) research is tapping the most predictive indicators for a specific population. This study has sought to examine predictors of QoL for fathers and mothers of children with Autistic Disorder. Two multiple regression analyses were performed for fathers (N=70) and mothers (N=114) of children with Autistic Disorder. Six predictors were entered into the regression equation: Parental Distress (PD), Parent-Child Dysfunction Interaction (PCDI), Difficult Child Characteristics (DC), Household income, and the child's with Autistic Disorder age and number of siblings. The analyses revealed that only PD was a significant predictor for both parent's QoL, whereas DC, household income, and number of siblings were able to predict only mothers' QoL. To our knowledge, this is the first study to focus on predictors of QoL among both fathers and mothers of children with Autistic Disorder. The results from the current study can have several implications for professionals and researchers targeting the primary force contributing to the wellbeing of children with Autistic Disorder, the parents.

    2001-03-01

    Autistic disorder (MIM 209850) is currently viewed as a neurodevelopmental disease. Reelin plays a pivotal role in the development of laminar structures including the cerebral cortex, hippocampus, cerebellum and of several brainstem nuclei. Neuroanatomical evidence is consistent with Reelin involvement in autistic disorder. In this study, we describe several polymorphisms identified using RNA-SSCP and DNA sequencing. Association and linkage were assessed comparing 95 Italian patients to 186 ethnically-matched controls, and using the transmission/disequilibrium test and haplotype-based haplotype relative risk in 172 complete trios from 165 families collected in Italy and in the USA. Both case-control and family-based analyses yield a significant association between autistic disorder and a polymorphic GGC repeat located immediately 5' of the reelin gene (RELN) ATG initiator codon, as well as with specific haplotypes formed by this polymorphism with two single-base substitutions located in a splice junction in exon 6 and within exon 50. Triplet repeats located in 5' untranslated regions (5'UTRs) are indicative of strong transcriptional regulation. Our findings suggest that longer triplet repeats in the 5'UTR of the RELN gene confer vulnerability to autistic disorder. PMID:11317216

    PubMed

    VanderLaan, Doug P; Leef, Jonathan H; Wood, Hayley; Hughes, S Kathleen; Zucker, Kenneth J

    2015-06-01

    Gender dysphoria (GD) and autism spectrum disorder (ASD) are associated. In 49 GD children (40 natal males), we examined ASD risk factors (i.e., birth weight, parental age, sibling sex ratio) in relation to autistic traits. Data were gathered on autistic traits, birth weight, parents' ages at birth, sibling sex ratio, gender nonconformity, age, maternal depression, general behavioral and emotional problems, and IQ. High birth weight was associated with both high gender nonconformity and autistic traits among GD children. Developmental processes associated with high birth weight are, therefore, likely to underlie the GD-ASD link either directly or indirectly. The present study is the first to provide quantitative data bearing on possible mechanisms that lead GD and ASD to co-occur. PMID:25503304

    PubMed

    Westwood, Heather; Eisler, Ivan; Mandy, William; Leppanen, Jenni; Treasure, Janet; Tchanturia, Kate

    2016-03-01

    Interest in the link between Autism Spectrum Disorder (ASD) and Anorexia Nervosa (AN) has led to estimates of the prevalence of autistic traits in AN. This systematic review and meta-analysis assessed the use of the Autism-Spectrum Quotient (AQ) or abbreviated version (AQ-10) to examine whether patients with AN have elevated levels of autistic traits. Seven studies were identified and subsequent meta-analysis indicated that those with AN appear to have significant difficulties of a manner characteristic of ASD, relative to controls. Whilst this analysis supports previous indications of higher prevalence of ASD in AN, the aetiology of these traits remains unclear. Studies using more robust clinical measures of ASD within AN are needed to confirm what self-report measures appear to show. PMID:26542816

  4. QEEG characteristics and spectrum weighted frequency for children diagnosed as autistic spectrum disorder

    PubMed Central

    2010-01-01

    Background Autistic spectrum disorders are a group of neurological and developmental disorders associated with social, communication, sensory, behavioral and cognitive impairments, as well as restricted, repetitive patterns of behavior, activities, or interests. The aim of this study was a) to analyze QEEG findings of autistic patients and to compare the results with data base; and b) to introduce the calculation of spectrum weighted frequency (brain rate) as an indicator of general mental arousal in these patients. Results Results for Q-EEG shows generally increased delta-theta activity in frontal region of the brain. Changes in QEEG pattern appeared to be in a non-linear correlation with maturational processes. Brain rate measured in CZ shows slow brain activity (5. 86) which is significantly lower than normal and corresponds to low general mental arousal. Recent research has shown that autistic disorders have as their basis disturbances of neural connectivity. Neurofeedback seems capable of remediating such disturbances when these data are considered as part of treatment planning. Conclusions Prognosis of this pervasive disorder depends on the intellectual abilities: the better intellectual functioning, the possibilities for life adaptation are higher QEEG shows generally increased delta-theta activity in frontal region of the brain which is related to poor cognitive abilities. Brain rate measured in CZ shows slow brain activity related to under arousal. Pharmacotherapy combined with behavior therapy, social support and especially neurofeedback technique promise slight improvements PMID:20920283

    PubMed

    Hare, Dougal Julian; Mellor, Christine; Azmi, Sabiha

    2007-01-01

    People with autistic spectrum disorders (ASD) have difficulties in recalling recently experienced events, which is dependent upon intact functioning of several aspects of 'self awareness'. The current study examined impaired episodic recall in ASD and its relationship to specific impairments in aspects of 'self awareness'. Between-group (participants with learning disabilities with and without autistic spectrum disorder) experimental design examining free and cued recall of table-top activities that were either self-experienced by participants or observed being performed by the experimenter. Participants with ASD did not show superiority of free recall for self-experienced events over observed events, nor for recall of other-experienced events over self-experienced events, but did demonstrate a superiority for cued recall of self-experienced events. The implications for theory and practice are discussed. PMID:16839739

    Purpose. Immune system of some autistic patients could be abnormally triggered by gluten/casein assumption. The prevalence of antibodies to gliadin and milk proteins in autistic children with paired/impaired intestinal permeability and under dietary regimen either regular or restricted is reported. Methods. 162 ASDs and 44 healthy children were investigated for intestinal permeability, tissue-transglutaminase (tTG), anti-endomysium antibodies (EMA)-IgA, and total mucosal IgA to exclude celiac disease; HLA-DQ2/-DQ8 haplotypes; total systemic antibodies (IgA, IgG, and IgE); specific systemic antibodies: α-gliadin (AGA-IgA and IgG), deamidated–gliadin-peptide (DGP-IgA and IgG), total specific gliadin IgG (all fractions: α, β, γ, and ω), β-lactoglobulin IgG, α-lactalbumin IgG, casein IgG; and milk IgE, casein IgE, gluten IgE, -lactoglobulin IgE, and α-lactalbumin IgE. Results. AGA-IgG and DPG-IgG titers resulted to be higher in ASDs compared to controls and are only partially influenced by diet regimen. Casein IgG titers resulted to be more frequently and significantly higher in ASDs than in controls. Intestinal permeability was increased in 25.6% of ASDs compared to 2.3% of healthy children. Systemic antibodies production was not influenced by paired/impaired intestinal permeability. Conclusions. Immune system of a subgroup of ASDs is triggered by gluten and casein; this could be related either to AGA, DPG, and Casein IgG elevated production or to impaired intestinal barrier function.

  7. Early interpersonal neurobiological assessment of attachment and autistic spectrum disorders

    PubMed Central

    Schore, Allan N.

    2014-01-01

    There is now a strong if not urgent call in both the attachment and autism literatures for updated, research informed, clinically relevant interventions that can more effectively assess the mother infant dyad during early periods of brain plasticity. In this contribution I describe my work in regulation theory, an overarching interpersonal neurobiological model of the development, psychopathogenesis, and treatment of the early forming subjective self system. The theory models the psychoneurobiological mechanisms by which early rapid, spontaneous and thereby implicit emotionally laden attachment communications indelibly impact the experience-dependent maturation of the right brain, the “emotional brain.” Reciprocal right-lateralized visual-facial, auditory-prosodic, and tactile–gestural non-verbal communications lie at the psychobiological core of the emotional attachment bond between the infant and primary caregiver. These affective communications can in turn be interactively regulated by the primary caregiver, thereby expanding the infant’s developing right brain regulatory systems. Regulated and dysregulated bodily based communications can be assessed in order to determine the ongoing status of both the infant’s emotional and social development as well as the quality and efficiency of the infant–mother attachment relationship. I then apply the model to the assessment of early stages of autism. Developmental neurobiological research documents significant alterations of the early developing right brain in autistic infants and toddlers, as well profound attachment failures and intersubjective deficits in autistic infant–mother dyads. Throughout I offer implications of the theory for clinical assessment models. This work suggests that recent knowledge of the social and emotional functions of the early developing right brain may not only bridge the attachment and autism worlds, but facilitate more effective attachment and autism models of early

    ABSTRACT Objective: the aim of this study was to provide evidence that DMSA detoxification treatments cause a reduction of the heavy metal burden in the autistic, and that this reduction lessens neurological symptoms associated with ASD (Autistic Spectrum Disorder). Method: The participants were 44 children, age 3 to 9 years of age, with Autistic Spectrum Disorder (ASD) according to Diagnostic and Statistical Manual of Mental Disorders 4t Edition, (DMS-IV). The severity of the autistics symptomatologiy had been measured by the Childhood Autism Rating Scale (SCARS). We collected urine samples before and after the DMSA challenge test, comparing urine metal output. We also compared the results of the DMSA detoxification(=the urine challenge test) with behavioral effects, typical for ASD. Results: The DMSA challenge test increased the urine metal output for a number of potentially toxic metals. Statistically significant difference were noted between the baseline urine and DMSA challenge test regarding the level of cadmium, mercury, and lead (P=0.006, P=0.049, and P=0.008 respectively). We also noted that behavioral effects, typical for ASD (autism spectrum disorders) were reduced with this method of detoxification. A comparison between CARS Subscales and Total Score before and after a 6-month chelation program showed greatest improvements for Verbal and nonverbal communication (P <0.001), Taste, Smell and Touch (P 0.001) and Relating to People (P 0.005). Other improvements were noted for Adaptation to Change and Improvement. Conclusion: DMSA chelation increased the urinary output of toxic and neurotoxic metals. Our data supports evidence that detoxification treatment with oral DMSA has beneficial effect on ASD patients. PMID:23400264

    Autism spectrum disorder (ASD) and Alzheimer's disease (AD) are neurodevelopmental and neurodegenerative disorders respectively, with devastating effects not only on the individual but also the society. Collectively, a number of factors contribute to the expression of ASD and AD. It is of utmost curiosity that these disorders express at different stages of life and there is an involvement of certain susceptible genes. This genetic basis makes the background of common associations like memory deficits, cognition changes, demyelination, oxidative stress and inflammation, an integral part of both disorders. Modern technology resulting in genetically modified crops and increase in gadgets emitting electromagnetic frequencies have resulted in enhanced risks for neurological dysfunctions and disorders like ASD and AD. Subsequent advances in the psychological, pharmacological, biochemical and nutritional aspects of the disorders have resulted in the development of newer therapeutic approaches. The common clinical features like language impairment, executive functions, and motor problems have been discussed along with the patho-physiological changes, role of DNA methylation, myelin development, and heavy metals in the expression of these disorders. Psychopharmacological and nutritional approaches towards the reduction and management of risk factors have gained attention from the researchers in recent years. Current major therapies either target the inflammatory pathways or reduce cellular oxidative stress. This contribution focuses on the commonalities of the two disorders. PMID:26996178

    In light of the recently reported neuropathologic and neurochemical abnormalities of the cholinergic pathways in autism, donepezil, a cholinesterase inhibitor, is a potentially useful agent in the treatment of cognitive and behavioral symptoms observed in this disorder. A retrospective pilot study was conducted to determine whether donepezil is effective in the treatment of children and adolescents with autism. Eight patients (mean age = 11.0 +/- 4.1 years; range 7-19 years) who met Diagnostic and Statistical Manual of Mental Disorders (4th edition) criteria for autistic disorder were openly treated with donepezil. All patients were on concomitant psychoactive medications. Four of these patients (50%) demonstrated significant improvement as assessed by the Aberrant Behavior Checklist and the Clinical Global Impression Scale. Decreases in the Irritability and Hyperactivity subscales were observed, but no changes in the Inappropriate Speech, Lethargy, and Stereotypies subscales were noted. Limited and transient side effects were reported, with one patient experiencing gastrointestinal disturbances and another reporting mild irritability. Double-blind, placebo-controlled investigations are needed to provide further evidence of the potential benefits of donepezil to patients with autistic disorder. PMID:12427297

    2015-02-01

    The purpose of this cross-sectional study was to examine coping strategies as mediators and moderators between stress and quality of life (QoL) among parents of children with autistic disorder. The convenience sample of the study consisted of 184 parents of children with autistic disorder. Advanced statistical methods for analyses of mediator and moderator effects of coping strategies were used. The results revealed that 'accepting responsibility' was the only mediator strategy in the relationship between stress and QoL. The results also revealed that only 'seeking social support' and 'escape avoidance' were moderator strategies in the relationship between stress and QoL. This study is perhaps the first to investigate the mediating and moderating effects of coping on QoL of parents of children with autistic disorder. Recommendations for practice and future research are presented. PMID:23868562

    Studies have shown considerable evidence of visual dysfunction in autism spectrum disorders. Anomalies in visual information processing can have a major effect on the life quality of individuals with autism spectrum disorders. We summarise the hypotheses and theories underlying neural aetiologies and genetic factors that cause these disorders, as well as the possible influences of unusual sensory processing on the communications and behaviour characterised by the autistics. In particular, we review the impact of these dysfunctions on visual performance. PMID:27161596

    There is a co-morbidity between autism spectrum behaviour disorders and deafness in children. Their behavioural difficulties may appear primary and/or secondary to hearing deprivation. In this paper, we present how we manage those patients on the base of our clinical experience. The auditory assessment must be based on subjective tests taking account of their special reactions. It needs objective tests to complete and help the behavioural responses. The hearing aids amplification is increased progressively, to allow the development of a tolerance to the sounds world. The multidisciplinary team tends to open them to the world and to the communication. PMID:16676561

    A large body of research has reported visual perception deficits in both people with dyslexia and autistic spectrum disorders. In this study, we compared form and motion coherence detection between a group of adults with high-functioning autism, a group with Asperger's disorder, a group with dyslexia, and a matched control group. It was found that motion detection was intact in dyslexia and Asperger. Individuals with high-functioning autism showed a general impaired ability to detect coherent form and motion. Participants with Asperger's syndrome showed lower form coherence thresholds than the dyslexic and normally developing adults. The results are discussed with respect to the involvement of the dorsal and ventral pathways in developmental disorders. PMID:18034294

    2000-04-01

    We have been examining the developmental process of affective communication in infants with autistic spectrum disorders from the viewpoint of relationship disturbance through our developmental and psychopathological studies on autism. In particular, the role of internal representation of the mother in the process of development of affective communication is discussed through the presentation of two cases diagnosed as autistic spectrum disorder in early infancy. In these cases, we postulate approach-avoidance motivational conflict as the primary factor impeding development of affective communication, focusing therapeutic intervention on this perspective. As a result, attachment behavior was remarkably improved in the children, but affective communication with their mothers was not readily improved. Taking up the mothers' own internal representation in mother-infant psychotherapy, in particular, the mothers' problems in attachment behavior with their own mothers in infancy precipitated transition in the mothers' internal representation of their children, leading to active evolution in mother-child interaction and development in affective communication between mother and child. In this context, the basis and significance of internal representation of both parties being determinants in the quality of mother-child communication are discussed. PMID:10803821

    2006-01-01

    An association between autistic spectrum disorder and imitative impairment might result from dysfunction in mirror neurons (MNs) that serve to relate observed actions to motor codings. To explore this hypothesis, we employed a functional magnetic resonance imaging (fMRI) protocol previously used to identify the neural substrate of imitation, and human MN function, to compare 16 adolescent males of normal intelligence with autistic spectrum disorder (ASD) and age, sex and IQ matched controls. In the control group, in accord with previous findings, we identified activity attributable to MNs in areas of the right parietal lobe. Activity in this area was less extensive in the ASD group and was absent during non-imitative action execution. Broca's area was minimally active during imitation in controls. Differential patterns of activity during imitation and action observation in ASD and controls were most evident in an area at the right temporo-parietal junction also associated with a 'theory of mind' (ToM) function. ASD participants also failed to show modulation of left amygdala activity during imitation that was evident in the controls. This may have implications for understanding the imitation of emotional stimuli in ASD. Overall, we suggest that ASD is associated with altered patterns of brain activity during imitation, which could stem from poor integration between areas serving visual, motor, proprioceptive and emotional functions. Such poor integration is likely to adversely affect the development of ToM through imitation as well as other aspects of social cognitive function in ASD. PMID:16140346

    2016-08-01

    The present web-based study (N = 840) aimed to illuminate the cognitive mechanisms underlying self-disorders in autism. Initially, participants selected three self-defining memories. Then, we assessed their capacity to give meaning to these events (i.e., meaning making), their tendency to scrutinize autobiographical memory to better understand themselves (i.e., self-continuity function of autobiographical memory) and their clarity of self-concept. The results showed that individuals with high autistic traits (ATs) had a lower clarity of self-concept than control participants. Meaning making was also reduced in AT individuals and mediated the relation between AT and self-concept clarity. Our results suggest that the reduced clarity of self-concept in AT individuals is related to an impaired capacity to make meaning of important past life events. PMID:27101235

    Individuals with autism spectrum disorder (ASD) are thought to lack self-awareness and to experience difficulty empathizing with others. Although these deficits have been demonstrated in previous studies, most of the target stimuli were constructed for typically developing (TD) individuals. We employed judgment tasks capable of indexing self-relevant processing in individuals with and without ASD. Fourteen Japanese men and 1 Japanese women with high-functioning ASD (17–41 years of age) and 13 Japanese men and 2 TD Japanese women (22–40 years of age), all of whom were matched for age and full and verbal intelligence quotient scores with the ASD participants, were enrolled in this study. The results demonstrated that the ventromedial prefrontal cortex was significantly activated in individuals with ASD in response to autistic characters and in TD individuals in response to non-autistic characters. Although the frontal–posterior network between the ventromedial prefrontal cortex and superior temporal gyrus participated in the processing of non-autistic characters in TD individuals, an alternative network was involved when individuals with ASD processed autistic characters. This suggests an atypical form of empathy in individuals with ASD toward others with ASD. PMID:25332405

    In this report we aim to explore severe deficits in facial affect recognition in three boys all of whom meet the criteria of Asperger's syndrome (AS), as well as overt prosopagnosia in one (B) and covert prosopagnosia in the remaining two (C and D). Subject B, with a familially-based talent of being highly gifted in physics and mathematics, showed no interest in people, a quasi complete lack of comprehension of emotions, and very poor emotional reactivity. The marked neuropsychological deficits were a moderate prosopagnosia and severely disordered recognition of facial emotions, gender and age. Expressive facial emotion, whole body psychomotor expression and speech prosody were quasi absent as well. In all three boys these facial processing deficits were more or less isolated, and general visuospatial functions, attention, formal language and scholastic performances were normal or even highly developed with the exception of deficient gestalt perception in B. We consider the deficient facial emotion perception as an important pathogenetic symptom for the autistic behaviour in the three boys. Prosopagnosia, the absent facial and bodily expression, and speech prosody were important but varying co-morbid disorders. The total clinical picture of non-verbal disordered communication is a complex of predominantly bilateral and/or right hemisphere cortical deficits. Moreover, in B, insensitivity to pain, smells, noises and internal bodily feelings suggested a more general emotional anaesthesia and/or a deficient means of expression. It is possible that a limbic component might be involved, thus making affective appreciation also deficient. PMID:11315539

  9. Judicial Perceptions of Media Portrayals of Offenders with High Functioning Autistic Spectrum Disorders

    In recent years, sensational media reporting focusing on crimes committed by those diagnosed with or thought to have High Functioning Autistic Spectrum Disorders (hfASDs) has caused societal speculation that there is a link between the disorder and violent criminality. No research exists on how and if the judiciary understands and is affected by this coverage. Therefore this study aims to examine how judges perceive and are influenced by media attention surrounding hfASDs and criminality. Semi-structured interviews were conducted with 21 California Superior Court Judges, including questions on media portrayal. Judges perceived general media portrayals of hfASDs in both positive and negative ways. However, almost all judges who had experienced media coverage surrounding hfASDs and criminality identified it as misleading and harmful to public perceptions of the disorder. These findings suggest judges are not exempt from media attention surrounding violence and hfASDs, and they recognize the potential adverse effects of this negative coverage. Although judges’ report their opinions are not affected, the results demonstrate that judges are worried that the public and potentially other criminal justice actors are adversely affected and will continue to be moving forward.

    Findings from research in animal models and humans have shown a clear role for the neuropeptide oxytocin (OT) on complex social behaviors. This is also true in the context of autism spectrum disorder (ASD). Previous studies on peripheral OT concentrations in children and young adults have reported conflicting results with the initial studies presenting mainly decreased OT plasma levels in ASD compared to healthy controls. Our study therefore aimed to further investigate changes in peripheral OT concentrations as a potential surrogate for the effects observed in the central nervous system (CNS) in ASD. OT plasma concentrations were assessed in 19 male children and adolescents with ASD, all with an IQ > 70 (age 10.7 ± 3.8 years), 17 healthy male children (age 13.6 ± 2.1 years) and 19 young male patients with attention deficit hyperactivity disorder (ADHD) as a clinical control group (age 10.4 ± 1.9 years) using a validated radioimmunoassay. Analysis of covariance revealed significant group differences in OT plasma concentrations (F(2, 48) = 9.574, p < 0.001, η2 = 0.285; plasma concentrations ASD 19.61 ± 7.12 pg/ml, ADHD 8.05 ± 5.49 pg/ml, healthy controls 14.43 ± 9.64 pg/ml). Post hoc analyses showed significantly higher concentrations in children with ASD compared to ADHD (p < 0.001). After Bonferroni correction, there was no significant difference in ASD in comparison with healthy controls (p = 0.132). A significant strong correlation between plasma OT and autistic symptomatology, assessed by the Autism Diagnostic Observation Schedule, was observed in the ASD group (p = 0.013, r = 0.603). Patients with ADHD differed from healthy control children by significantly decreased OT concentrations (p = 0.014). No significant influences of the covariates age, IQ, medication and comorbidity could be seen. Our preliminary results point to a correlation of OT plasma concentrations with autistic symptom load in children with ASD and a modulation of the OT system also in

    Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in socialization, communication, and behavior. Many investigators have described the anatomical abnormalities in autistic brains, in an attempt to correlate them with the manifestations of ASD. Herein, we reviewed all the available literature about the neuroanatomical findings in ASD available via "PubMed" and "Google Scholar." References found in review articles were also searched manually. There was substantial discrepancy throughout the literature regarding the reported presence and significance of neuroanatomical findings in ASD, and this is thoroughly discussed in the present review.

  13. Investigating mechanisms underlying neurodevelopmental phenotypes of autistic and intellectual disability disorders: a perspective

    2013-01-01

    Brain function and behavior undergo significant plasticity and refinement, particularly during specific critical and sensitive periods. In autistic and intellectual disability (ID) neurodevelopmental disorders (NDDs) and their corresponding genetic mouse models, impairments in many neuronal and behavioral phenotypes are temporally regulated and in some cases, transient. However, the links between neurobiological mechanisms governing typically normal brain and behavioral development (referred to also as “neurotypical” development) and timing of NDD impairments are not fully investigated. This perspective highlights temporal patterns of synaptic and neuronal impairment, with a restricted focus on autism and ID types of NDDs. Given the varying known genetic and environmental causes for NDDs, this perspective proposes two strategies for investigation: (1) a focus on neurobiological mechanisms underlying known critical periods in the (typically) normal-developing brain; (2) investigation of spatio-temporal expression profiles of genes implicated in monogenic syndromes throughout affected brain regions. This approach may help explain why many NDDs with differing genetic causes can result in overlapping phenotypes at similar developmental stages and better predict vulnerable periods within these disorders, with implications for both therapeutic rescue and ultimately, prevention.

    Motor stereotypies are defined as patterned, repetitive, purposeless movements. These stigmatizing motor behaviors represent one manifestation of the third core criterion for an Autistic Disorder (AD) diagnosis, and are becoming viewed as potential early markers of autism. Moreover, motor stereotypies might be a tangible expression of the underlying neurobiology of this neurodevelopmental disorder. In this study, we videoscored stereotypies recorded during semi-structured play sessions from school age children with AD. We examined the effect of severity and persistence over time of stereotypies on brain volumetric changes. Our findings confirmed that the brain volume of school age children with AD is, on average, larger than that of age-matched typically developing children. However, we have failed to detect any sign of volumetric differences in brain regions thought to be particularly linked to the pathophysiology of stereotypies. This negative finding may suggest that, at least with respect to motor stereotypies, functional rather than structural alterations might be the underpinning of these disruptive motor manifestations of autism.

    The search for quality of life and the trend towards continual improvement has today become a true reference which guides most social organizations. The bodies which offer support to persons with Autistic Spectrum Disorder (referred to hereon as ASD) have not gone untouched by the influence of this concept of quality. The serious difficulties which are associated with this disorder affect the main areas of one ??s personal development: socialisation, communication, comprehension, and adaptation to ones environment, and they require that organizations promote integral networks of resources which guarantee a lifetime of quality services and support. The difficulties of assessing quality of life in persons with ASD from the subjective perspective, make it especially necessary to find valid indicators that help us to favour certain conditions in the ASD person ??s environment. This identified need is justification for the objective put forward: to design an instrument capable of being used to assess the quality of life of persons with ASD, made up of a Guide of Indicators, which organizations and programmes can then use to promote favourable conditions.

    Biofeedback potentially provides non-invasive, effective psychophysiological interventions for psychiatric disorders. The encompassing purpose of this review was to establish how biofeedback interventions have been used to treat select psychiatric disorders [anxiety, autistic spectrum disorders, depression, dissociation, eating disorders, schizophrenia and psychoses] to date and provide a useful reference for consultation by clinicians and researchers planning to administer a biofeedback treatment. A systematic search of EMBASE, MEDLINE, PsycINFO, and WOK databases and hand searches in Applied Psychophysiology and Biofeedback, and Journal of Neurotherapy, identified 227 articles; 63 of which are included within this review. Electroencephalographic neurofeedback constituted the most investigated modality (31.7%). Anxiety disorders were the most commonly treated (68.3%). Multi-modal biofeedback appeared most effective in significantly ameliorating symptoms, suggesting that targeting more than one physiological modality for bio-regulation increases therapeutic efficacy. Overall, 80.9% of articles reported some level of clinical amelioration related to biofeedback exposure, 65.0% to a statistically significant (p < .05) level of symptom reduction based on reported standardized clinical parameters. Although the heterogeneity of the included studies warrants caution before explicit efficacy statements can be made. Further development of standardized controlled methodological protocols tailored for specific disorders and guidelines to generate comprehensive reports may contribute towards establishing the value of biofeedback interventions within mainstream psychiatry.

    Screening for autism in individuals with generalized social anxiety disorder (GSAD) is complicated by symptom overlap between GSAD and autism spectrum disorder (ASD). We examined the prevalence of self-reported autistic traits within a sample of participants with a diagnosis of GSAD (n=37) compared to individuals without a GSAD diagnosis (NOSAD; n=26). Of the GSAD sample participants, 70.84% self-reported autistic traits above a cut-off of 65 on the Autism Quotient-Short (AQ-S) and reported significantly more autistic traits on 3 of 5 AQ-S subscales compared to the NOSAD group. Diagnosis uniquely predicted variation in the social skills subscale above and beyond the other subscales and other predictors. Furthermore, variation in the social skills subscale largely explained group differences on the other subscales. Our results suggest caution in utilizing measures like the AQ-S with clinical populations characterized by social difficulties such as individuals with a GSAD diagnosis. PMID:26766150

    People in the general population are typically very poor at detecting changes in pictures of complex scenes. The degree of this 'change blindness', however, varies with the content of the scene: when an object is semantically important or contextually inappropriate, people may be more effective at detecting changes. Two experiments investigated change blindness in people with autism, who are known from previous research to be efficient in detecting features yet poor at processing stimuli for meaning and context. The first experiment measured the effect of semantic information while the second investigated the role of context in directing attention. In each task, participants detected the dissimilarity between pairs of images. Both groups showed a main effect of image type in both experimental tasks, showing that their attention was directed to semantically meaningful and contextually inappropriate items. However, the autistic group also showed a greater difficulty detecting changes to semantically marginal items in the first experiment. Conclusions point to a normal selection of items for attention in people with autism spectrum disorders, although this may be combined with difficulty switching or disengaging attention.

    Children with autistic spectrum disorder (ASD) are reported to have difficulties with narrative language but little is known about how this affects their production of fictional stories. In this study, we aimed to establish whether fictional narratives of children with ASD differed from those of typically developing children and if performance was commensurate with levels of oral language. Fictional stories produced by 27 high functioning children with ASD, aged 11-14 yrs, were compared with those of language and age matched groups of typically developing children. Differences were found between the children with ASD and comparison groups in structural, evaluative and global features of their stories indicating specific difficulties with this form of narrative. Stories of the ASD group were shorter and contained fewer causal statements than those of both comparison groups and sentences were less grammatically complex than those of the age match but not the language match group. In global measures, the stories of the ASD group were impoverished relative to both comparison groups. The results are discussed in relation to cognitive theories of autism and language development.

    ABSTRACT General information: Autism is a severe developmental disorder which involves social withdrawal, communication deficits, and stereotypic/repetitive behavior. The pathophysiological etiologies which precipitate autism symptoms remain elusive and controversial in many cases, but both genetic and environmental factors (and their interactions) have been implicated. While autism is considered multicausal, environmental factors have received significant attention. International discussion has ocused on neurotoxins such as mercury and lead, suggesting that these and other toxic metals contribute to the development of the disorder. An epidemiological study released in 2006 (Palmer et al.) linking Toxic Release Inventory (TRI) data on mercury to special education data in Texas reported a 61% increase in autism prevalence rates (or 17% adjusted) per 1000 pounds of mercury released into the environment (1). We attempted to further evaluate whether exposure to variable environmental contributes to the genesis of autistic spectrum disorder, and thus is a factor increasing the risk for developing autism symptoms in utero or in early childhood. Purpose: The purpose of this study is to examine possible environmental risk factors and sources of exposure to mercury and other heavy metals in children with autism spectrum disorder versus controls. Through laboratory diagnostics we are able to distinguish between present and past exposure (i.e. hair analysis measurements reflect past exposure), urinary excretion levels of unprovoked urine represent immediate exposure. By assessing a spectrum of trace elements and heavy metals in hair and urine of both autistic and control groups, we focused on the participants≈ past and present exposure. Methodology: The participants were 25 Autistic Spectrum Disorder (ASD) children (22 boys and 3 girls) between the age of 3 and 9 years. They were either diagnosed previously by other psychiatrist, psychologist, and developmental pediatrician

  3. Hypnosis Without Empathy? Perspectives From Autistic Spectrum Disorder and Stage Hypnosis.

    Despite volumes of published studies supporting the efficacy of hypnosis for ego-strengthening, performance, and physical and psychological disorders, the precise nature of hypnosis, and in particular, the neurobiological underpinnings of trance-phenomenon, remains tenuous at best. With his empathic involvement theory of hypnosis, Wickramasekera II (2015) brings us closer to an understanding of the elusive nature of hypnotic processes by proposing a bridging of two long-standing and seemingly incongruent theories of hypnosis (i.e., neodissociative versus socio-cognitive). Borrowing from neuroscientific studies of empathy, the empathic involvement theory maintains that empathy, beyond any other human dynamic (including emotions, behavior, personality, and imagination), facilitates and enhances hypnotic experiences for both recipient and provider alike. By the same token, one can reasonably infer from the empathic involvement theory that non-empathic individuals are less likely to benefit from hypnosis. With this perspective in mind, the empathic involvement theory's identification of empathy as an apparent "Holy Grail" of the neural underpinnings and precise nature of hypnosis may be challenged on a number of grounds. Individuals with autistic spectrum disorder, especially those suffering from alexithymia, have been identified as empathy deficient, and therefore according to the empathic involvement theory would be classified as "low-hypnotizable," yet empirical studies, albeit limited in number, suggest otherwise. Furthermore, hypnotic inductions of audience volunteers by stage hypnotists challenge the empathic involvement theory's supposition that empathy is a required component of hypnosis. It is this author's contention that empathy is a beneficial, though not essential, element of successful hypnosis. PMID:26675158

    Abnormalities in melatonin physiology may be involved or closely linked to the pathophysiology and behavioral expression of autistic disorder, given its role in neurodevelopment and reports of sleep-wake rhythm disturbances, decreased nocturnal melatonin production, and beneficial therapeutic effects of melatonin in individuals with autism. In addition, melatonin, as a pineal gland hormone produced from serotonin, is of special interest in autistic disorder given reported alterations in central and peripheral serotonin neurobiology. More specifically, the role of melatonin in the ontogenetic establishment of circadian rhythms and the synchronization of peripheral oscillators opens interesting perspectives to ascertain better the mechanisms underlying the significant relationship found between lower nocturnal melatonin excretion and increased severity of autistic social communication impairments, especially for verbal communication and social imitative play. In this article, first we review the studies on melatonin levels and the treatment studies of melatonin in autistic disorder. Then, we discuss the relationships between melatonin and autistic behavioral impairments with regard to social communication (verbal and non-verbal communication, social interaction), and repetitive behaviors or interests with difficulties adapting to change. In conclusion, we emphasize that randomized clinical trials in autism spectrum disorders are warranted to establish potential therapeutic efficacy of melatonin for social communication impairments and stereotyped behaviors or interests.

    Anxiety and Autistic Disorder (AD) are both neurological conditions and both disorders share some features that make it difficult to precisely allocate specific symptoms to each disorder. HPA and SAM axis activities have been conclusively associated with anxiety, and may provide a method of validating anxiety rating scale assessments given by parents and their children with AD about those children. Data from HPA axis (salivary cortisol) and SAM axis (salivary alpha amylase) responses were collected from a sample of 32 high-functioning boys (M age=11yr) with an Autistic Disorder (AD) and were compared with the boys' and their mothers' ratings of the boys' anxiety. There was a significant difference between the self-ratings given by the boys and ratings given about them by their mothers. Further, only the boys' self-ratings of their anxiety significantly predicted the HPA axis responses and neither were significantly related to SAM axis responses. Some boys showed cortisol responses which were similar to that previously reported in children who had suffered chronic and severe anxiety arising from stressful social interactions. As well as suggesting that some boys with an AD can provide valid self-assessments of their anxiety, these data also point to the presence of very high levels of chronic HPA-axis arousal and consequent chronic anxiety in these boys.

    This study focused on the coping strategies of parents' with children with autistic spectrum disorders (ASD) and the relation between these strategies and parenting styles. Coping strategies were measured using the Sense of Coherence Scale (SOC) and the Purpose in Life Test (PIL-R). Parental attitudes toward loving care, stress, worry, and guilt feelings were assessed using the Family Impact Questionnaire. Two groups of participants were included: parents with children with ASD (EG) (n = 66) and a matched control group (CG) (n = 66). Paired Samples t-Test and Pearson's r correlation were used as methods of analysis. Main results distinguished significant (p < .001 to .003) differences between the EG and CG for almost all variables included. The M level of coping strategy was much higher for the CG than for the EG. SOC showed a stress-reducing effect in both the EG and CG. PIL-R explained 50% of the variance in SOC for the EG and 33% for the CG. The only significant gender difference in the EG was on SOC indicating a higher sense of coherence among the fathers and probably an indicator of a stronger burnout effect of the mothers.

    Background Williams-Beuren syndrome (WBS), a rare developmental disorder caused by deletion of contiguous genes at 7q11.23, has been characterized by strengths in socialization (overfriendliness) and communication (excessive talkativeness). WBS has been often considered as the polar opposite behavioral phenotype to autism. Our objective was to better understand the range of phenotypic expression in WBS and the relationship between WBS and autistic disorder. Methodology The study was conducted on 9 French individuals aged from 4 to 37 years old with autistic disorder associated with WBS. Behavioral assessments were performed using Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) scales. Molecular characterization of the WBS critical region was performed by FISH. Findings FISH analysis indicated that all 9 patients displayed the common WBS deletion. All 9 patients met ADI-R and ADOS diagnostic criteria for autism, displaying stereotypies and severe impairments in social interaction and communication (including the absence of expressive language). Additionally, patients showed improvement in social communication over time. Conclusions The results indicate that comorbid autism and WBS is more frequent than expected and suggest that the common WBS deletion can result in a continuum of social communication impairment, ranging from excessive talkativeness and overfriendliness to absence of verbal language and poor social relationships. Appreciation of the possible co-occurrence of WBS and autism challenges the common view that WBS represents the opposite behavioral phenotype of autism, and might lead to improved recognition of WBS in individuals diagnosed with autism.

    Over a 10-year period in a Down syndrome Clinic, 11 children and adolescents were encountered with a history of new-onset (8) or worsening (3) autistic characteristics. Ten of the 11 (91%) had cognitive decline to a dementia-like state and 9 of the 11 (82%) new-onset insomnia. The mean age at which symptoms developed was 11.4 years (standard deviation = 3.6 years; range 5-14 years), an older age than usual for autistic regression in Down syndrome. Ten of 11 cases (91%) had elevated ("positive") thyroperoxidase antibody titers compared to only 5 of 21 (23%) age-matched control subjects with Down syndrome (P < .001). At follow-up at a mean age of 20.7 years (standard deviation = 3.9 years), 8 of the 11 (73%) were at least somewhat better. Down syndrome disintegrative disorder seems an appropriate name for this newly recognized clinical association, which may be due to autoimmunity. PMID:25367918

    It has been reported that autism is a hypoglutamatergic disorder. Therefore, it was of interest to assess the efficacy of piracetam, a positive modulator of AMPA-sensitive glutamate receptors in autistic disorder. About 40 children between the ages three and 11 years (inclusive) with a DSM IV clinical diagnosis of autism and who were outpatients from a specialty clinic for children were recruited. The children presented with a chief complaint of severely disruptive symptoms related to autistic disorder. Patients were randomly allocated to piracetam + risperidone (Group A) or placebo + risperidone (Group B) for a 10-week, double-blind, placebo-controlled study. The dose of risperidone was titrated up to 2 mg/day for children between 10 and 40 kg and 3 mg/day for children weighting above 40 kg. The dose of piracetam was titrated up to 800 mg/day. Patients were assessed at baseline and after 2, 4, 6, 8 and 10 weeks of starting medication. The measure of the outcome was the Aberrant Behavior Checklist-Community (ABC-C) Rating Scale (total score). The ABC-C Rating Scale scores improved with piracetam. The difference between the two protocols was significant as indicated by the effect of group, the between subjects factor (F = 5.85, d.f. = 1, P = 0.02). The changes at the endpoint compared with baseline were: -11.90 +/- 3.79 (mean +/- SD) and -5.15 +/- 3.04 for group A and B respectively. A significant difference was observed on the change in scores in the ABC-C Rating Scale in week 10 compared with baseline in the two groups (t = 6.017, d.f. = 38, P < 0.0001). The results suggest that a combination of atypical antipsychotic medications and a glutamate agent such as piracetam, might have increase synergistic effects in the treatment of autism.

    The aim in the current study was to investigate the early development of joint attention, eye contact and affect during the first 2 years of life, by using retrospective parental interviews and analyses of home videos of infants who were later diagnosed with Autistic Disorder (AD). The 36 children with AD and the 27 matched control children were all aged between 3 and 5 years at recruitment. Reported anomalies in gaze and affect emerged in the children with AD as early as the first 6 months of life, generally becoming more severe just prior to the second birthday. Video data confirmed these anomalies from as early as the first year. Joint attention impairments were found throughout the second year of life. The results suggest that early dyadic behaviours-eye contact and affect-may play a role in the joint attention impairment in AD. PMID:17917803

    Research indicates that autism is the extreme end of a continuously distributed trait. The Social Responsiveness Scale (SRS) and the Social and Communication Disorders Checklist (SCDC) aim to assess autistic traits. The objective of this study was to compare their clinical validity. The SRS showed sensitivities of .74 to .80 and specificities of .69 to 1.00 for autism. Sensitivities were .85 to .90 and specificities .28 to.82 for the SCDC. Correlations with the ADI-R, ADOS and SCQ were higher for the SRS than for the SCDC. The SCDC seems superior to the SRS to screen for unspecific social and communicative deficits including autism. The SRS appears more suitable than the SCDC in clinical settings and for specific autism screening. PMID:20422277

    2009-10-01

    The relationship between dyadic (eye contact and affect) and triadic (joint attention) behaviours in infancy, and social responsiveness at pre-school age, was investigated in 36 children with Autistic Disorder. Measures of eye contact and affect, and joint attention, including requesting behaviours, were obtained retrospectively via parental interviews and home videos from 0- to- 24-months of age. Concurrent measures (3-5 years) included social responsiveness to another's distress and need for help. Early dyadic behaviours observed in home videos, but not as reported by parents, were associated with later social responsiveness. Many triadic behaviours (from both parent-reports and home video) were also associated with social responsiveness at follow-up. The results are consistent with the view that early dyadic and triadic behaviours, particularly sharing attention, are important for the development of later social responsiveness. PMID:19475503

    Challenging behaviours restrict opportunities and choices for people with autistic spectrum disorders (ASD) and frequently lead to inappropriate and costly service interventions. Managing challenging behaviours of people with autism is an important area of research. This paper examines some of the evidence for the role of physiological arousal influencing these behaviours. Evidence from the emerging literature about sensory differences is examined. It is proposed that sensory reactivity is associated with hyperarousal; catatonic type behaviours are associated with low levels of reactivity (hypoarousal). A low arousal approach is proposed as a generalised strategy to managing challenging behaviours with ASD. The use of non-contingent reinforcement and antecedent control strategies are recommended for use with challenging behaviours which have a sensory component. Examples are provided to illustrate the approach. The implications of arousal and the use of physical interventions are discussed. It is proposed that arousal is a construct which has significant heuristic value for researchers and practitioners. PMID:25462491

    There is increasing evidence that abnormalities of fatty acid and membrane phospholipid metabolism play a part in a wide range of neurodevelopmental and psychiatric disorders. This proposal is discussed here in relation to attention-deficit/hyperactivity disorder (ADHD), dyslexia, developmental coordination disorder (dyspraxia) and the autistic spectrum. These are among the most common neurodevelopmental disorders of childhood, with significant implications for society as well as for those directly affected. However, controversy still surrounds both the identification and management of these conditions, and while their aetiology is recognized as being complex and multifactorial, little progress has yet been made in elucidating predisposing factors at the biological level. An overview is provided here of the contents of this Special Issue, which contains a selection of reports from a unique multidisciplinary workshop involving both researchers and clinicians. Its purpose was to explore the possibility that ADHD, dyslexia, dyspraxia and autism fall within a phospholipid spectrum of disorders. This proposal could explain the high degree of co-morbidity between these conditions, their aggregation within families and relation to other psychiatric disorders, and a range of associated features that are already well known at a clinical level. The existing evidence for fatty acid abnormalities in these disorders is summarized, and new approaches are outlined that have the potential to improve both the identification and the management of these and related neurodevelopmental and psychiatric conditions.

    In recent years, the advent of comparative genomic hybridization (CGH) and single nucleotide polymorphism (SNP) arrays and its use as a first genetic test for the diagnosis of patients with neurodevelopmental phenotypes has allowed the identification of novel submicroscopic chromosomal abnormalities (namely, copy number variants or CNVs), imperceptible by conventional cytogenetic techniques. The 3q13.31 microdeletion syndrome (OMIM #615433) has been defined as a genomic disorder mainly characterized by developmental delay, postnatal overgrowth, hypotonia, genital abnormalities in males, and characteristic craniofacial features. Although the 3q13.31 CNVs are variable in size, a 3.4 Mb recurrently altered region at 3q13.2-q13.31 has been recently described and non-allelic homologous recombination (NAHR) mediated by flanking human endogenous retrovirus (HERV-H) elements has been suggested as the mechanism of deletion formation. We expand the phenotypic spectrum associated with this recurrent deletion performing the clinical description of a 9-year-old female patient with autistic disorder, total absence of language, intellectual disability, anxiety disorder and disruptive, and compulsive eating behaviors. The array-based molecular karyotyping allowed the identification of a de novo recurrent 3q13.2-q13.31 deletion encompassing 25 genes. In addition, we compare her clinical phenotype with previous reports of patients with neurodevelopmental and behavioral disorders and proximal 3q microdeletions. Finally, we also review the candidate genes proposed so far for these phenotypes. PMID:26332054

    The anthropomorphic bias describes the finding that the perceived naturalness of a biological motion decreases as the human-likeness of a computer-animated agent increases. To investigate the anthropomorphic bias in autistic children, human or cartoon characters were presented with biological and artificial motions side by side on a touchscreen. Children were required to touch one that would grow while the other would disappear, implicitly rewarding their choice. Only typically developing controls depicted the expected preference for biological motion when rendered with human, but not cartoon, characters. Despite performing the task to report a preference, children with autism depicted neither normal nor reversed anthropomorphic bias, suggesting that they are not sensitive to the congruence of form and motion information when observing computer-animated agents' actions.

    In the DSM-5, 'Asperger's Disorder' was incorporated into 'Autistic Spectrum Disorder' (ASD). One key concern in this change has been that the ASD label will increase negative attitudes relative to the Asperger's label. To test this, we asked 465 American adults to read a vignette describing a child with autistic symptoms that included an ASD label, an Asperger's label, or no label, and rate their stigma and treatment attitudes (help-seeking and perceived effectiveness). Contrary to predictions, label did not impact stigma. Label did impact treatment attitudes, with greater help-seeking and perceived treatment effectiveness for both Asperger's and ASD labels. In sum, concern that the ASD label will increase negative perceptions, at least amongst the general public, is not supported. PMID:26043847

    The current review covers extant literature on pharmacotherapy for core symptoms of autism. The core symptoms of autism include impairments in social interaction and communication, as well as the presence of restricted and repetitive behaviors. There are no known efficacious treatments for the core social symptoms, although effects on repetitive behaviors are indicated with some data. While studies of fenfluramine, secretin, opiates, and mood stabilizers generally find no effect, mixed results suggest more research is needed on antidepressants and atypical antipsychotics. Newer lines of research, including cholinergic and glutamatergic agents and oxytocin, will be of considerable interest in the future. However, research on the treatment of core symptoms is plagued by limitations in study design, statistical power and other issues inherent to the study of treatments for autism (e.g., heterogeneity of the disorder) that continue to prevent the elucidation of efficacious treatments.

    Abstract Objective: The purpose of this study was to evaluate the long-term safety and efficacy of risperidone in treating irritability and related behaviors in children and adolescents with autistic disorders. Methods: In this 6 month (26 week) open-label extension (OLE) study, patients (5–17 years of age, who completed the previous fixed-dose, 6 week, double-blind [DB] phase) were flexibly dosed with risperidone based on body weight. The maximum allowed dose was 1.25 mg/day for those weighing 20 to <45 kg, and 1.75 mg/day for those weighing ≥45 kg. The study primarily assessed risperidone's safety; efficacy was assessed as a secondary end-point. Results: Fifty-six (71%) out of 79 enrolled patients completed the OLE; the most common discontinuations were for insufficient response (7 [9%]) or adverse events (AE) (5 [6%]). The most common (≥5% frequency in the total group) AEs were increased appetite (11% [n=9]); increased weight and vomiting (9% [n=7] each); sedation, pyrexia, and upper respiratory tract infection (8% [n=6] each); nasopharyngitis (6% [n=5]); and somnolence and fatigue (5% [n=4] each). Extrapyramidal AEs were reported in 6 (8%) patients. Increase in mean weight (11–15%) and body mass index (5–10%) occurred; one patient discontinued because of weight increase. One potentially prolactin-related AE (irregular menstruation) was reported. The risperidone high-dose group had the greatest mean improvement in sleep visual analog scale (24.6). All groups showed additional improvement in efficacy scale scores during the OLE. Conclusions: During this OLE, safety findings with risperidone treatment (maximum weight-based dose of 1.25 mg/day or 1.75 mg/day) were consistent with those observed in the DB phase, and with the current safety information for risperidone in autistic, psychiatric, and behavioral disorders. Patients experienced some additional improvement in irritability and related behaviors. Clinical Trials Registry: This phase-4

    The Autism Detection in Early Childhood (ADEC; Young, 2007) was developed as a Level 2 clinician-administered autistic disorder (AD) screening tool that was time-efficient, suitable for children under 3 years, easy to administer, and suitable for persons with minimal training and experience with AD. A best estimate clinical Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) diagnosis of AD was made for 70 children using all available information and assessment results, except for the ADEC data. A screening study compared these children on the ADEC with 57 children with other developmental disorders and 64 typically developing children. Results indicated high internal consistency (α = .91). Interrater reliability and test-retest reliability of the ADEC were also adequate. ADEC scores reliably discriminated different diagnostic groups after controlling for nonverbal IQ and Vineland Adaptive Behavior Composite scores. Construct validity (using exploratory factor analysis) and concurrent validity using performance on the Autism Diagnostic Observation Schedule (Lord et al., 2000), the Autism Diagnostic Interview-Revised (Le Couteur, Lord, & Rutter, 2003), and DSM-IV-TR criteria were also demonstrated. Signal detection analysis identified the optimal ADEC cutoff score, with the ADEC identifying all children who had an AD (N = 70, sensitivity = 1.0) but overincluding children with other disabilities (N = 13, specificity ranging from .74 to .90). Together, the reliability and validity data indicate that the ADEC has potential to be established as a suitable and efficient screening tool for infants with AD. PMID:24490680

    2012-01-01

    This study used fMRI to measure brain activity during adult processing of cries of infants with autistic disorder (AD) compared to cries of typically developing (TD) infants. Using whole brain analysis, we found that cries of infants with AD compared to those of TD infants elicited enhanced activity in brain regions associated with verbal and prosodic processing, perhaps because altered acoustic patterns of AD cries render them especially difficult to interpret, and increased activity in brain regions associated with emotional processing, indicating that AD cries also elicit more negative feelings and may be perceived as more aversive and/or arousing. Perceived distress engendered by AD cries related to increased activation in brain regions associated with emotional processing. This study supports the hypothesis that cry is an early and meaningful anomaly displayed by children with AD. It could be that cries associated with AD alter parent-child interactions much earlier than the time that reliable AD diagnosis normally occurs. PMID:22835685

    A variety of distinct phenotypes has been associated with supernumerary inv dup(15) chromosomes. Although different cytogenetic rearrangements have been associated with distinguishable clinical syndromes, precise genotype-phenotype correlations have not been determined. However, the availability of chromosome 15 DNA markers provides a means to characterize inv dup(15) chromosomes in detail to facilitate the determination of specific genotype-phenotype associations. We describe 2 patients with an autistic disorder, mental retardation, developmental delay, seizures, and supernumerary inv dup(15) chromosomes. Conventional and molecular cytogenetic studies confirmed the chromosomal origin of the supernumerary chromosomes and showed that the duplicated region extended to at least band 15q13. An analysis of chromosome 15 microsatellite CA polymorphisms suggested a maternal origin of the inv dup(15) chromosomes and biparental inheritance of the two intact chromosome 15 homologs. The results of this study add to the existing literature which suggests that the clinical phenotype of patients with a supernumerary inv dup(15) chromosome is determined not only by the extent of the duplicated region, but by the dosage of genes located within band 15q13 and the origin of the normal chromosomes 15. 21 refs., 2 figs., 1 tab.

    In the present study, the cytogenetic and molecular cytogenetic analysis of 90 children with autism and their mothers (18 subjects) was carried out. Chromosome fragility and abnormalities were found in four cases: mos 47,XXX[98]/ 46,XX[2]; 46,XY,r(22)(p11q13); 46,XY,inv(2)(p11.2q13),16qh-; 46Y,fra(X)(q27.3)16qh-. Using C-banding and quantitative fluorescent in situ hybridization (FISH), the significantly increased incidence of heterochromatic region variation was shown in autism as compared to the controls (48 and 16%, respectively). Pericentric 9phqh inversion was not characteristic of the patients with autism whereas heterochromatic variations 1phqh, 9qh+ and 16qh- were more frequent in autism (p<0,05). Basing on the data obtained, a possible role of position effect in autism pathogenesis as well as a potential of heterochromatic region variation analysis for the search of biological markers of autistic spectrum disorders are discussed.

    Persons with autism spectrum disorders (ASD) are known to have difficulty in eye contact (EC). This may make it difficult for their partners during face to face communication with them. To elucidate the neural substrates of live inter-subject interaction of ASD patients and normal subjects, we conducted hyper-scanning functional MRI with 21 subjects with autistic spectrum disorder (ASD) paired with typically-developed (normal) subjects, and with 19 pairs of normal subjects as a control. Baseline EC was maintained while subjects performed real-time joint-attention task. The task-related effects were modeled out, and inter-individual correlation analysis was performed on the residual time-course data. ASD-Normal pairs were less accurate at detecting gaze direction than Normal-Normal pairs. Performance was impaired both in ASD subjects and in their normal partners. The left occipital pole (OP) activation by gaze processing was reduced in ASD subjects, suggesting that deterioration of eye-cue detection in ASD is related to impairment of early visual processing of gaze. On the other hand, their normal partners showed greater activity in the bilateral occipital cortex and the right prefrontal area, indicating a compensatory workload. Inter-brain coherence in the right IFG that was observed in the Normal-Normal pairs (Saito et al., 2010) during EC diminished in ASD-Normal pairs. Intra-brain functional connectivity between the right IFG and right superior temporal sulcus (STS) in normal subjects paired with ASD subjects was reduced compared with in Normal-Normal pairs. This functional connectivity was positively correlated with performance of the normal partners on the eye-cue detection. Considering the integrative role of the right STS in gaze processing, inter-subject synchronization during EC may be a prerequisite for eye cue detection by the normal partner. PMID:23060772

    Hahn, Chris; Salajegheh, Mohammad Kian

    2016-01-01

    The myotonic disorders are a heterogeneous group of genetically determined diseases that are unified by the presence of myotonia, which is defined as failure of muscle relaxation after activation. The presentation of these disorders can range from asymptomatic electrical myotonia, as seen in some forms of myotonia congenita (MC), to severe disability with muscle weakness, cardiac conduction defects, and other systemic features as in myotonic dystrophy type I (DM1). In this review, we describe the clinical features and pathophysiology of the different myotonic disorders, their laboratory and electrophysiologic findings and briefly review the currently available treatments.

  18. The ongoing dissection of the genetic architecture of autistic spectrum disorder

    PubMed Central

    2011-01-01

    The development of robust, non-hypothesis based case/control studies has led to a large push forward towards identifying common genetic variants that contribute to complex traits. However, despite many attempts, the search for common disease-predisposing variants in childhood developmental disorders has largely failed. Recently, a role for rare causal variants and de novo mutations is emerging in the genetic architecture of some of these disorders, particularly those that incur a large degree of selection against the phenotype. In this paper, we examine these data and use classic genetic epidemiological approaches to gain insights into the genetic architecture of ASD. Future studies using next generation sequencing should elucidate the precise role de novo mutations play in disorders traditionally thought to have resulted from polygenic or common disease, common variants inheritance.

  19. Can Neurotypical Individuals Read Autistic Facial Expressions? Atypical Production of Emotional Facial Expressions in Autism Spectrum Disorders.

    2016-02-01

    The difficulties encountered by individuals with autism spectrum disorder (ASD) when interacting with neurotypical (NT, i.e. nonautistic) individuals are usually attributed to failure to recognize the emotions and mental states of their NT interaction partner. It is also possible, however, that at least some of the difficulty is due to a failure of NT individuals to read the mental and emotional states of ASD interaction partners. Previous research has frequently observed deficits of typical facial emotion recognition in individuals with ASD, suggesting atypical representations of emotional expressions. Relatively little research, however, has investigated the ability of individuals with ASD to produce recognizable emotional expressions, and thus, whether NT individuals can recognize autistic emotional expressions. The few studies which have investigated this have used only NT observers, making it impossible to determine whether atypical representations are shared among individuals with ASD, or idiosyncratic. This study investigated NT and ASD participants' ability to recognize emotional expressions produced by NT and ASD posers. Three posing conditions were included, to determine whether potential group differences are due to atypical cognitive representations of emotion, impaired understanding of the communicative value of expressions, or poor proprioceptive feedback. Results indicated that ASD expressions were recognized less well than NT expressions, and that this is likely due to a genuine deficit in the representation of typical emotional expressions in this population. Further, ASD expressions were equally poorly recognized by NT individuals and those with ASD, implicating idiosyncratic, rather than common, atypical representations of emotional expressions in ASD.

  20. Increased Intra-Participant Variability in Children with Autistic Spectrum Disorders: Evidence from Single-Trial Analysis of Evoked EEG

    PubMed Central

    Milne, Elizabeth

    2011-01-01

    Intra-participant variability in clinical conditions such as autistic spectrum disorder (ASD) is an important indicator of pathophysiological processing. The data reported here illustrate that trial-by-trial variability can be reliably measured from EEG, and that intra-participant EEG variability is significantly greater in those with ASD than in neuro-typical matched controls. EEG recorded at the scalp is a linear mixture of activity arising from muscle artifacts and numerous concurrent brain processes. To minimize these additional sources of variability, EEG data were subjected to two different methods of spatial filtering. (i) The data were decomposed using infomax independent component analysis, a method of blind source separation which un-mixes the EEG signal into components with maximally independent time-courses, and (ii) a surface Laplacian transform was performed (current source density interpolation) in order to reduce the effects of volume conduction. Data are presented from 13 high functioning adolescents with ASD without co-morbid ADHD, and 12 neuro-typical age-, IQ-, and gender-matched controls. Comparison of variability between the ASD and neuro-typical groups indicated that intra-participant variability of P1 latency and P1 amplitude was greater in the participants with ASD, and inter-trial α-band phase coherence was lower in the participants with ASD. These data support the suggestion that individuals with ASD are less able to synchronize the activity of stimulus-related cell assemblies than neuro-typical individuals, and provide empirical evidence in support of theories of increased neural noise in ASD.

    PubMed Central

    Smith, Alastair D.

    2015-01-01

    On the basis of relative strengths that have been attributed to the autistic cognitive profile, it has been suggested by a number of theorists that people with autism spectrum disorders (ASD) excel at spatial navigational tasks. However, many of these claims have been made in the absence of a close inspection of extant data in the scientific literature, let alone anecdotal reports of daily navigational experiences. The present review gathers together published studies that have attempted to explicitly address functional components of navigation in ASD populations, including assays of wayfinding, large-scale search, and path integration. This inspection reveals a pattern of apparent strengths and weaknesses in navigational abilities, thus illustrating the necessity for a more measured and comprehensive approach to the understanding of spatial behavior in ASD.

    Atypical benign partial epilepsy (ABPE) of childhood or pseudo-Lennox syndrome is a form of idiopathic focal epilepsy characterized by multiple seizure types, focal and/or generalized epileptiform discharges, continuous spike-wave during sleep (CSWS), and sometimes reversible neurocognitive deficits. There are few reported cases of ABPE describing detailed correlative longitudinal follow-up of the various associated neurocognitive, language, social communicative, or motor deficits, in parallel with the epilepsy. Furthermore, the molecular inheritance pattern for ABPE and the wider spectrum of epilepsy aphasia disorders have yet to be fully elucidated. We describe the phenotype-genotype study of a boy with ABPE with follow-up from ages 5 to 13 years showing acquired oromotor and, later, a specific lexical semantic and pervasive developmental disorder. Exome sequencing identified variants in SCN9A, CPA6, and SCNM1. A direct role of the epilepsy in the pathogenesis of the oromotor and neurocognitive deficits is apparent. PMID:27504264

    Autism is a neurodevelopmental disorder of unknown origin that manifests in early childhood. Autism spectrum disorders (ASDs) refer to a broader group of neurobiological conditions, pervasive developmental disorders. Despite several arguments for a strong genetic contribution, the molecular basis in most cases remains unexplained. Several studies have reported an association between ASDs and mutations in the mitochondrial DNA (mtDNA) molecule. In order to confirm these causative relationship, we screened 21 individuals with idiopathic ASDs for a number of the most common mtDNA mutations. We identified two patients with candidate mutations: m.6852G>A that produces an amino acid change of glycine to serine in the MT-CO1 gene and m.8033A>G (Ile→Val) in the MT-CO2 gene. Overall, these findings support the notion that mitochondrial mutations are associated with ASDs. Additional studies are needed to further define the role of mitochondrial defects in the pathogenesis of autism. PMID:24052731

    Autism, like schizophrenia, are heterogeneous diseases, which are directed by both genetic factors and external influences in the early stages of development. Knowledge about the similarities and differences of these disorders can help early diagnosis and treatment. Patients with autism have specific cognitive difficulties in social relations. They are characterized by impairment of social interaction, communication and behavioral flexibility. The severity of the delay the development of autistic children, clinical and psychological indicators is correlated with an increase in the high frequency of spontaneous EEG activity. Cognitive task in autistic children, unlike normal persons, does not lead to a significant restructuring of high-frequency EEG activity, which may be a violation of the reaction mechanism to external stimuli and behavioral disorders. Abnormality in high-frequency components of EEG reactivity on cognitive task, the perception of human faces and visual illusions as well as the inadequate system of mirror neurons, can be considered common mechanisms underlying disorders of autism and schizophrenia. These general mechanisms may be considered as related to violation of the inhibition-exitation balance, controlled via GABA-transmission and NMDA-receptors. A multidimensional study of patterns of disontogenesis in autism, in addition to detailing the clinical picture of disease and rehabilitation activities, allows us to clear the fundamental understanding of the brain.

    There is overwhelming evidence that autism spectrum disorder (ASD) is related to altered brain connectivity. While these alterations are starting to be well characterized in subjects where the clinical picture is fully expressed, less is known on their earlier developmental course. In the present study we systematically reviewed current knowledge on structural connectivity in ASD infants and toddlers. We searched PubMed and Medline databases for all English language papers, published from year 2000, exploring structural connectivity in populations of infants and toddlers whose mean age was below 30 months. Of the 264 papers extracted, four were found to be eligible and were reviewed. Three of the four selected studies reported higher fractional anisotropy values in subjects with ASD compared to controls within commissural fibers, projections fibers, and association fibers, suggesting brain hyper-connectivity in the earliest phases of the disorder. Similar conclusions emerged from the other diffusion parameters assessed. These findings are reversed to what is generally found in studies exploring older patient groups and suggest a developmental course characterized by a shift toward hypo-connectivity starting at a time between two and four years of age.

    PubMed Central

    2013-01-01

    The peer-reviewed literature investigating the relationship between pain expression and perception of pain in individuals with ASD is sparse. The aim of the present systematic PRIMSA review was twofold: first, to see what evidence there is for the widely held belief that individuals with ASD are insensitive to pain or have a high pain threshold in the peer-reviewed literature and, second, to examine whether individuals with ASD react or express pain differently. Fifteen studies investigating pain in individuals with ASD were identified. The case studies all reported pain insensitivity in individuals with ASD. However, the majority of the ten experimental studies reviewed indicate that the idea that individuals with ASD are pain insensitive needs to be challenged. The findings also highlight the strong possibility that not all children with ASD express their physical discomfort in the same way as a neurotypical child would (i.e., cry, moan, seek comfort, etc.) which may lead caregivers and the medical profession to interpret this as pain insensitivity or incorrectly lead them to believe that the child is in no pain. These results have important implications for the assessment and management of pain in children with ASD. PMID:23843740

    2014-08-01

    This study examined the relationship between child language skills and parent and child gestures of 58 youths with and without an autism spectrum disorder (ASD) diagnosis. Frequencies and rates of total gesture use as well as five categories of gestures (deictic, conventional, beat, iconic, and metaphoric) were reliably coded during the collaborative Tower of Hanoi task. Children with ASD had lower Peabody Picture Vocabulary Test scores and gestured less and at lower rates compared to typically developing children. Gesture use was unrelated to vocabulary for typically developing children, but positively associated with vocabulary for those with ASD. Demographic correlates of gesturing differed by group. Gesture may be a point of communication intervention for families with children with ASD. PMID:24535577

    Autism spectrum disorders (ASDs) are a heterogeneous group of neurodevelopmental disorders, including childhood autism, atypical autism, and Asperger syndrome, with an estimated prevalence of 1.0-2.5% in the general population. ASDs have a complex multifactorial etiology, with genetic causes being recognized in only 10-20% of cases. Recently, copy-number variants (CNVs) have been shown to contribute to over 10% of ASD cases. We have applied a custom-designed oligonucleotide array comparative genomic hybridization with an exonic coverage of over 1700 genes, including 221 genes known to cause autism and autism candidate genes, in a cohort of 145 patients with ASDs.

    Autism spectrum disorders (ASDs) are a heterogeneous group of neurodevelopmental disorders, including childhood autism, atypical autism, and Asperger syndrome, with an estimated prevalence of 1.0–2.5% in the general population. ASDs have a complex multifactorial etiology, with genetic causes being recognized in only 10–20% of cases. Recently, copy-number variants (CNVs) have been shown to contribute to over 10% of ASD cases. We have applied a custom-designed oligonucleotide array comparative genomic hybridization with an exonic coverage of over 1700 genes, including 221 genes known to cause autism and autism candidate genes, in a cohort of 145 patients with ASDs. The patients were classified according to ICD-10 standards and the Childhood Autism Rating Scale protocol into three groups consisting of 45 individuals with and 69 individuals without developmental delay/intellectual disability (DD/ID), and 31 patients, in whom DD/ID could not be excluded. In 12 patients, we have identified 16 copy-number changes, eight (5.5%) of which likely contribute to ASDs.

    Auditory hypersensitivities are a common feature of autism spectrum disorder (ASD). In the present study, the effectiveness of a novel intervention, the listening project protocol (LPP), was evaluated in two trials conducted with children diagnosed with ASD. LPP was developed to reduce auditory hypersensitivities. LPP is based on a theoretical “neural exercise” model that uses computer altered acoustic stimulation to recruit the neural regulation of middle ear muscles. Features of the intervention stimuli were informed by basic research in speech and hearing sciences that has identified the specific acoustic frequencies necessary to understand speech, which must pass through middle ear structures before being processed by other components of the auditory system. LPP was hypothesized to reduce auditory hypersensitivities by increasing the neural tone to the middle ear muscles to functionally dampen competing sounds in frequencies lower than human speech. The trials demonstrated that LPP, when contrasted to control conditions, selectively reduced auditory hypersensitivities. These findings are consistent with the polyvagal theory, which emphasizes the role of the middle ear muscles in social communication. PMID:25136545

    The ability to remember faces is critical for the development of social competence. From childhood to adulthood, we acquire a high level of expertise in the recognition of facial images, and neural processes become dedicated to sustaining competence. Many people with autism spectrum disorder (ASD) have poor face recognition memory; changes in hairstyle or other non-facial features in an otherwise familiar person affect their recollection skills. The observation implies that they may not use the configuration of the inner face to achieve memory competence, but bolster performance in other ways. We aimed to test this hypothesis by comparing the performance of a group of high-functioning unmedicated adolescents with ASD and a matched control group on a "surprise" face recognition memory task. We compared their memory for unfamiliar faces with their memory for images of houses. To evaluate the role that is played by peripheral cues in assisting recognition memory, we cropped both sets of pictures, retaining only the most salient central features. ASD adolescents had poorer recognition memory for faces than typical controls, but their recognition memory for houses was unimpaired. Cropping images of faces did not disproportionately influence their recall accuracy, relative to controls. House recognition skills (cropped and uncropped) were similar in both groups. In the ASD group only, performance on both sets of task was closely correlated, implying that memory for faces and other complex pictorial stimuli is achieved by domain-general (non-dedicated) cognitive mechanisms. Adolescents with ASD apparently do not use domain-specialized processing of inner facial cues to support face recognition memory. PMID:23894016

    Background There is evidence that children with Attention Deficit Hyperactivity Disorder (ADHD) and Autistic Spectrum Disorder (ASD) have lower omega-3 polyunsaturated fatty acid (n-3 PUFA) levels compared with controls and conflicting evidence regarding omega-6 (n-6) PUFA levels. Objectives This study investigated whether erythrocyte n-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were lower and n-6 PUFA arachidonic acid (AA) higher in children with ADHD, ASD and controls, and whether lower n-3 and higher n-6 PUFAs correlated with poorer scores on the Australian Twin Behaviour Rating Scale (ATBRS; ADHD symptoms) and Test of Variable Attention (TOVA) in children with ADHD, and Childhood Autism Rating Scale (CARS) in children with ASD. Methods Assessments and blood samples of 565 children aged 3–17 years with ADHD (n = 401), ASD (n = 85) or controls (n = 79) were analysed. One-way ANOVAs with Tukey’s post-hoc analysis investigated differences in PUFA levels between groups and Pearson’s correlations investigated correlations between PUFA levels and ATBRS, TOVA and CARS scores. Results Children with ADHD and ASD had lower DHA, EPA and AA, higher AA/EPA ratio and lower n-3/n-6 than controls (P<0.001 except AA between ADHD and controls: P = 0.047). Children with ASD had lower DHA, EPA and AA than children with ADHD (P<0.001 for all comparisons). ATBRS scores correlated negatively with EPA (r = -.294, P<0.001), DHA (r = -.424, P<0.001), n-3/n-6 (r = -.477, P<0.001) and positively with AA/EPA (r = .222, P <.01). TOVA scores correlated positively with DHA (r = .610, P<0.001), EPA (r = .418, P<0.001) AA (r = .199, P<0.001), and n-3/n-6 (r = .509, P<0.001) and negatively with AA/EPA (r = -.243, P<0.001). CARS scores correlated significantly with DHA (r = .328, P = 0.002), EPA (r = -.225, P = 0.038) and AA (r = .251, P = 0.021). Conclusions Children with ADHD and ASD had low levels of EPA, DHA and AA and high ratio of n-6/n-3 PUFAs and these

    Several reports have described salutary effects such as decreased physical aggression and improved social responsiveness being associated with the administration of high doses of pyridoxine and magnesium (HDPM) in open-labeled and controlled studies of patients with autism. Despite this fact, this intervention remains controversial. A 10-week double-blind, placebo-controlled trial was undertaken to examine both the efficacy and safety of HDPM in autism. Twelve patients were enrolled, and 10 patients (mean age 6 years 3 months) were able to complete the study. HDPM at an average dose of 638.9 mg of pyridoxine and 216.3 mg of magnesium oxide was ineffective in ameliorating autistic behaviors as assessed by the Children's Psychiatric Rating Scale (CPRS), the Clinical Global Impression Scale, and the NIMH Global Obsessive Compulsive Scale. Furthermore, no clinically significant side effects were noted during HDPM administration. A trend for a transient change on the CPRS was found that was possibly due to a placebo response. This study raises doubts about the clinical effectiveness of HDPM in autistic disorder. PMID:9261669

    Two experiments examined whether over-selectivity is the product of a post-acquisition performance deficit, rather than an attention problem. In both experiments, children with Autistic Spectrum Disorder were presented with a trial-and-error discrimination task using two, two-element stimuli and over-selected in both studies. After behavioral control by the previously over-selected stimulus was extinguished, behavioral control by the previously under-selected cue emerged without direct training. However, this effect was only found in higher-functioning children, and not with more severely impaired children. These findings suggest that over-selectivity is not simply due to a failure to attend to all of the stimuli presented. They also suggest that extinction of over-selected stimuli may be a fruitful line of intervention for clinical intervention for some individuals. PMID:18787937

    Gender differences in autism spectrum disorder (ASD) symptoms and associated problem behaviours over development may provide clues regarding why more males than females are diagnosed with ASD. Fifty-six high-functioning children with ASD, and 44 typically developing controls, half of the participants female, were assessed at baseline (aged 7-12 years) and one-year later, collecting measures of autism, attention and anxiety symptoms, school placement and support information. Findings indicated no gender differences in autistic symptoms. Males were more hyperactive and received more integration-aide support in mainstream schools, and females were more socially anxious. Overall, similar gender profiles were present across two time points. Lower hyperactivity levels in females might contribute to their under-identification. Implications are discussed using a biopsychosocial model of gender difference. PMID:24105364

    The first purpose of this article is to review the literature related to the use of computers with autistic individuals. Although only a limited number of applications have been reported, the potential of the computer to facilitate the progress of autistic persons is promising. The second purpose is to identify specific learning problems or styles associated with autism from the research literature and link these with the unique aspects of computer-based instruction. For example, the computer's role in improving the motivation of autistic individuals is related to its capacity to analyze the reinforcing qualities of a particular event interactively and immediately for each user. Finally, recommendations that may enable computers to be maximally beneficial in assessing the learning process and remediating learning problems are offered. Two such recommendations are selecting appropriate software and integrating computer instruction within the classroom environment. PMID:6549182

  20. TOPICAL REVIEW: Supersolidity and disorder

    Balibar, Sébastien; Caupin, Frédéric

    2008-04-01

    A solid is called 'supersolid' if it exhibits superfluid properties. Supersolidity is a paradoxical phenomenon whose understanding has become a major challenge since 2004, when Kim and Chan first observed what could be mass superflow through solid helium 4. In this review, we describe how successive experiments indicated that what was observed in helium 4 was not intrinsic properties of the crystalline state as originally proposed 35 years before. Disorder coming from how the solid is grown (dislocations, grain boundaries and other interfaces, liquid or glassy regions, impurities...) was shown to play an essential role. However, one does not know yet which type of disorder is involved or by which mechanism it leads to the observed properties. Furthermore, all the experimental features probably cannot be explained by a common mechanism. Recent measurements of the shear modulus of helium 4 crystals could even be explained without the need of any superfluidity. In fact, many theoretical predictions need to be checked experimentally, so the whole issue is far from understood. Even some crucial experiments would need to be repeated more systematically. The present review of the experimental observations and theoretical scenarios raises a series of questions which call for answers.

    In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), gambling disorder was recategorized from the “Impulse Control Disorder” section to the newly expanded “Substance-related and Addictive Disorders” section. With this move, gambling disorder has become the first recognized nonsubstance behavioral addiction, implying many shared features between gambling disorder and substance use disorders. This review examines these similarities, as well as differences, between gambling and substance-related disorders. Diagnostic criteria, comorbidity, genetic and physiological underpinnings, and treatment approaches are discussed. PMID:27051333

    Aggression, self-injurious behavior, and severe tantrums are impairing symptoms frequently experienced by individuals with autism spectrum disorders. Despite US Food and Drug Administration approval of two atypical antipsychotics targeting these symptoms in youth with autistic disorder, they remain frequently drug refractory. We define drug-refractory aggression, self-injurious behavior, and severe tantrums in people with autism spectrum disorders as behavioral symptoms requiring medication adjustment despite previous trials of risperidone and aripiprazole or previous trials of three psychotropic drugs targeting the symptom cluster, one of which was risperidone or aripiprazole. We reviewed the medical records of individuals of all ages referred to our clinic for autism spectrum disorder diagnostic evaluation, as well as pharmacotherapy follow-up notes for all people meeting autism spectrum disorder criteria, for drug-refractory symptoms. Among 250 consecutively referred individuals, 135 met autism spectrum disorder and enrollment criteria, and 53 of these individuals met drug-refractory symptom criteria. Factors associated with drug-refractory symptoms included age 12 years or older (p < 0.0001), diagnosis of autistic disorder (p = 0.0139), and presence of intellectual disability (p = 0.0273). This pilot report underscores the significance of drug-refractory aggression, self-injurious behavior, and severe tantrums; suggests the need for future study clarifying factors related to symptom development; and identifies the need for focused treatment study of this impairing symptom domain.

    Females with high-functioning ASD are known to camouflage their autistic symptoms better than their male counterparts, making them prone to being under-ascertained and delayed in diagnostic assessment. Thus far the underlying cognitive processes that enable such successful socio-communicative adaptation are not well understood. The current results show sex-related differences in the cognitive profile of ASD individuals, which were diagnosed late in life exclusively. Higher verbal abilities were found in males (n = 69) as opposed to higher processing speed and better executive functions in females with ASD (n = 38). Since both sexes remained unidentified during childhood and adolescence, these results are suggestive for sex-distinctive cognitive strategies as an alternative to typically-developed reciprocal social behavior and social mimicry in high functioning ASD.

    Protein kinase C enzymes play an important role in signal transduction, regulation of gene expression and control of cell division and differentiation. The fsI and betaII isoenzymes result from the alternative splicing of the PKCbeta gene (PRKCB1), previously found to be associated with autism. We performed a family-based association study in 229 simplex and 5 multiplex families, and a postmortem study of PRKCB1 gene expression in temporocortical gray matter (BA41/42) of 11 autistic patients and controls. PRKCB1 gene haplotypes are significantly associated with autism (P<0.05) and have the autistic endophenotype of enhanced oligopeptiduria (P<0.05). Temporocortical PRKCB1 gene expression was reduced on average by 35 and 31% for the PRKCB1-1 and PRKCB1-2 isoforms (P<0.01 and <0.05, respectively) according to qPCR. Protein amounts measured for the PKCbetaII isoform were similarly decreased by 35% (P=0.05). Decreased gene expression characterized patients carrying the 'normal' PRKCB1 alleles, whereas patients homozygous for the autism-associated alleles displayed mRNA levels comparable to those of controls. Whole genome expression analysis unveiled a partial disruption in the coordinated expression of PKCbeta-driven genes, including several cytokines. These results confirm the association between autism and PRKCB1 gene variants, point toward PKCbeta roles in altered epithelial permeability, demonstrate a significant downregulation of brain PRKCB1 gene expression in autism and suggest that it could represent a compensatory adjustment aimed at limiting an ongoing dysreactive immune process. Altogether, these data underscore potential PKCbeta roles in autism pathogenesis and spur interest in the identification and functional characterization of PRKCB1 gene variants conferring autism vulnerability.

    The inclusion of animals in therapeutic activities, known as animal-assisted intervention (AAI), has been suggested as a treatment practice for autism spectrum disorder (ASD). This paper presents a systematic review of the empirical research on AAI for ASD. Fourteen studies published in peer-reviewed journals qualified for inclusion. The presentation of AAI was highly variable across the studies. Reported outcomes included improvements for multiple areas of functioning known to be impaired in ASD, namely increased social interaction and communication as well as decreased problem behaviors, autistic severity, and stress. Yet despite unanimously positive outcomes, most studies were limited by many methodological weaknesses. This review demonstrates that there is preliminary "proof of concept" of AAI for ASD and highlights the need for further, more rigorous research. PMID:23124442

    Autism spectrum disorder (ASD) affects about 1.4% of the population in South Asia but very few have access to any form of health care service. The objective of this study was to explore the beliefs and practices related to the care of children with ASD to inform strategies for intervention. In Pakistan, primary data were collected through in-depth interviews of parents (N = 15), while in India a narrative review of existing studies was conducted. The results show that the burden of care is almost entirely on the mother, leading to high levels of stress. Poor awareness of the condition in both family members and front-line health-providers leads to delay in recognition and appropriate management. There is considerable stigma and discrimination affecting children with autism and their families. Specialist services are rare, concentrated in urban areas, and inaccessible to the majority. Strategies for intervention should include building community and family support networks to provide respite to the main carer. In the absence of specialists, community members such as community health workers, traditional practitioners and even motivated family members could be trained in recognizing and providing evidence-based interventions. Such task-shifting strategies should be accompanied by campaigns to raise awareness so greater inclusivity can be achieved. PMID:26107996

    Cytogenetic and molecular cytogenetic analysis of children with autism (90 subjects) and their mothers (18 subjects) is presented. Anomalies and fragility were found in chromosome X in four cases of autism: mos 47,XXX[98]/46, XX[2]; 46,XY,r(22)(p11q13); 46,XY,inv(2)(p11.2q13),16qh-; and 46,Y,fra(X)(q27.3),16qh-. C staining and quantitative fluorescent in situ hybridization (FISH) were used to demonstrate a significant increase in the frequency of variations in the heterochromatin regions of chromosomes in children with autism as compared with a control group (48% and 16% respectively). Pericentric chromosome inversion 9phqh was not characteristic of patients with autism, while variation in heterochromatin regions 1phqh, 9qh+, and 16qh-were found significantly more frequently in children with autism. These data provide the basis for discussing the possible role of the gene position effect in the pathogenesis of autism and the possible search for biological markers of autistic disorders.

    Background The TPH2 gene encodes the enzyme responsible for serotonin (5-HT) synthesis in the Central Nervous System (CNS). Stereotypic and repetitive behaviors are influenced by 5-HT, and initial studies report an association of TPH2 alleles with childhood-onset obsessive-compulsive disorder (OCD) and with autism. GLO1 encodes glyoxalase I, the enzyme which detoxifies α-oxoaldehydes such as methylglyoxal in all living cells. The A111E GLO1 protein variant, encoded by SNP C419A, was identifed in autopsied autistic brains and proposed to act as an autism susceptibility factor. Hyperserotoninemia, macrocephaly, and peptiduria represent some of the best-characterized endophenotypes in autism research. Methods Family-based and case-control association studies were performed on clinical samples drawn from 312 simplex and 29 multiplex families including 371 non-syndromic autistic patients and 156 unaffected siblings, as well as on 171 controls. TPH2 SNPs rs4570625 and rs4565946 were genotyped using the TaqMan assay; GLO1 SNP C419A was genotyped by PCR and allele-specific restriction digest. Family-based association analyses were performed by TDT and FBAT, case-control by χ2, endophenotypic analyses for 5-HT blood levels, cranial circumference and urinary peptide excretion rates by ANOVA and FBAT. Results TPH2 alleles and haplotypes are not significantly associated in our sample with autism (rs4570625: TDT P = 0.27, and FBAT P = 0.35; rs4565946: TDT P = 0.45, and FBAT P = 0.55; haplotype P = 0.84), with any endophenotype, or with the presence/absence of prominent repetitive and stereotyped behaviors (motor stereotypies: P = 0.81 and 0.84, verbal stereotypies: P = 0.38 and 0.73 for rs4570625 and rs4565946, respectively). Also GLO1 alleles display no association with autism (191 patients vs 171 controls, P = 0.36; TDT P = 0.79, and FBAT P = 0.37), but unaffected siblings seemingly carry a protective gene variant marked by the A419 allele (TDT P < 0.05; patients vs

    Persons with autism spectrum disorders (ASD) are known to have difficulty in eye contact (EC). This may make it difficult for their partners during face to face communication with them. To elucidate the neural substrates of live inter-subject interaction of ASD patients and normal subjects, we conducted hyper-scanning functional MRI with 21 subjects with autistic spectrum disorder (ASD) paired with typically-developed (normal) subjects, and with 19 pairs of normal subjects as a control. Baseline EC was maintained while subjects performed real-time joint-attention task. The task-related effects were modeled out, and inter-individual correlation analysis was performed on the residual time-course data. ASD–Normal pairs were less accurate at detecting gaze direction than Normal–Normal pairs. Performance was impaired both in ASD subjects and in their normal partners. The left occipital pole (OP) activation by gaze processing was reduced in ASD subjects, suggesting that deterioration of eye-cue detection in ASD is related to impairment of early visual processing of gaze. On the other hand, their normal partners showed greater activity in the bilateral occipital cortex and the right prefrontal area, indicating a compensatory workload. Inter-brain coherence in the right IFG that was observed in the Normal-Normal pairs (Saito et al., 2010) during EC diminished in ASD–Normal pairs. Intra-brain functional connectivity between the right IFG and right superior temporal sulcus (STS) in normal subjects paired with ASD subjects was reduced compared with in Normal–Normal pairs. This functional connectivity was positively correlated with performance of the normal partners on the eye-cue detection. Considering the integrative role of the right STS in gaze processing, inter-subject synchronization during EC may be a prerequisite for eye cue detection by the normal partner. PMID:23060772

    This paper aimed to review currently available cohort studies of subjects with mood disorders such as major depressive disorder (MDD) and bipolar disorder (BD). Using the PubMed and KoreaMed databases, we reviewed eight major cohort studies. Most studies recruited participants with MDD and BD separately, so direct comparison of factors associated with diagnostic changes was difficult. Regular and frequent follow-up evaluations utilizing objective mood ratings and standardized evaluation methods in a naturalistic fashion are necessary to determine detailed clinical courses of mood disorders. Further, biological samples should also be collected to incorporate clinical findings in the development of new diagnostic and therapeutic approaches. An innovative cohort study that can serve as a platform for translational research for treatment and prevention of mood disorders is critical in determining clinical, psychosocial, neurobiological and genetic factors associated with long-term courses and consequences of mood disorders in Korean patients.

    2016-05-01

    Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in Assessment of autism spectrum disorders. Guilford Press, New York, 2008; Mottron in J Autism Dev Disord 34(1):19-27, 2004). However, previous studies suggest that while WISC-III and Raven's Progressive Matrices (RPM) provide similar estimates of non-autistic intelligence, autistic children perform significantly better on RPM (Dawson et al. in Psychol Sci 18(8):657-662, doi: 10.1111/j.1467-9280.2007.01954.x , 2007). The latest WISC version introduces substantial changes in subtests and index scores; thus, we asked whether WISC-IV still underestimates autistic intelligence. Twenty-five autistic and 22 typical children completed WISC-IV and RPM. Autistic children's RPM scores were significantly higher than their WISC-IV FSIQ, but there was no significant difference in typical children. Further, autistic children showed a distinctively uneven WISC-IV index profile, with a "peak" in the new Perceptual Reasoning Index. In spite of major changes, WISC-IV FSIQ continues to underestimate autistic intelligence. PMID:25308198

    Participatory research aims to increase the relevance and broaden the implementation of health research by involving those affected by the outcomes of health studies. Few studies within the field of neurodevelopmental disorders, particularly autism spectrum disorders, have involved autistic individuals as partners. This study sought to identify and characterize published participatory research partnerships between researchers and individuals with autism spectrum disorder or other neurodevelopmental disorders and examine the influence of participatory research partnerships on the research process and reported study outcomes. A search of databases and review of gray literature identified seven studies that described participatory research partnerships between academic researchers and individuals with autism spectrum disorder or other neurodevelopmental disorders. A comparative analysis of the studies revealed two key themes: (1) variations in the participatory research design and (2) limitations during the reporting of the depth of the partner's involvement. Both themes potentially limit the application and generalizability of the findings. The results of the review are discussed in relation to the use of evaluative frameworks for such participatory research studies to determine the potential benefits of participatory research partnerships within the neurodevelopmental and autism spectrum disorder populations.

    The etiology of autism spectrum disorders (ASDs) is complex and largely unclear. Among various lines of inquiry, many have suggested convergence onto disruptions in both neural circuitry and immune regulation/glial cell function pathways. However, the interpretation of the relationship between these two putative mechanisms has largely focused on the role of exogenous factors and insults, such as maternal infection, in activating immune pathways that in turn result in neural network abnormalities. Yet, given recent insights into our understanding of human neurodevelopment, and in particular the critical role of glia and the immune system in normal brain development, it is important to consider these putative pathological processes in their appropriate normal neurodevelopmental context. In this review, we explore the hypothesis that the autistic brain cellular phenotype likely represents intrinsic abnormalities of glial/immune processes constitutively operant in normal brain development that result in the observed neural network dysfunction. We review recent studies demonstrating the intercalated role of neural circuit development, the immune system, and glial cells in the normal developing brain, and integrate them with studies demonstrating pathological alterations in these processes in autism. By discussing known abnormalities in the autistic brain in the context of normal brain development, we explore the hypothesis that the glial/immune component of ASD may instead be related to intrinsic exaggerated/abnormal constitutive neurodevelopmental processes such as network pruning. Moreover, this hypothesis may be relevant to other neurodevelopmental disorders that share genetic, pathologic, and clinical features with autism. PMID:26379512

    Singleton, Clarence J; Ashwin, Chris; Brosnan, Mark

    2014-12-01

    Researchers have suggested that the two primary cognitive features of autism spectrum disorder (ASD), a drive toward nonsocial processing and a reduced drive toward social processing, may be unrelated to each other in the neurotypical (NT) population and may therefore require separate explanations. Drive toward types of processing may be related to physiological arousal to categories of stimuli, such as social (e.g., faces) or nonsocial (e.g., trains). This study investigated how autistic traits in an NT population might relate to differences in physiological responses to nonsocial compared with social stimuli. NT participants were recruited to examine these differences in those with high vs. low degrees of ASD traits. Forty-six participants (21 male, 25 female) completed the Autism Spectrum Quotient (AQ) to measure ASD traits before viewing a series of 24 images while skin conductance response (SCR) was recorded. Images included six nonsocial, six social, six face-like cartoons, and six nonsocial (relating to participants' personal interests). Analysis revealed that those with a higher AQ had significantly greater SCR arousal to nonsocial stimuli than those with a low AQ, and the higher the AQ, the greater the difference between SCR arousal to nonsocial and social stimuli. This is the first study to identify the relationship between AQ and physiological response to nonsocial stimuli, and a relationship between physiological response to both social and nonsocial stimuli, suggesting that physiological response may underlie the atypical drive toward nonsocial processing seen in ASD, and that at the physiological level at least the social and nonsocial in ASD may be related to one another.

    2007-06-01

    Eating disorders in adolescence are a public health concern with both personal costs and a financial burden for the community health services. This paper is a review of incidence and gender differences of eating disorders; comorbid psychopathology, including substance abuse, mood disorders, anxiety disorders and personality disorders; developmental and intellectual factors; family, socio-cultural functioning and birth order; self-injury and suicidal behaviour with health outcome and therapy success rate. We have also asked several questions from our clinical experience and tried to answer them with our clinical knowledge and based on literature review. Overall, there is an indication that therapy success is significantly correlated with (low) manifestation, specifically for social problems and aggressivity. Due to the complexity of factors involved in the manifestation of eating disorders, the inclusion of cognitive-behavioural therapy as well as family-oriented therapeutic concepts coupled with medical treatment would appear to offer an intervention inventory, which would be most effective in offering adolescents optimal treatment programmes. The implications of our review is discussed in terms of psychotherapeutic treatment plans for adolescents in clinical care. PMID:17519869

    Few studies have compared the efficacy of the Picture Exchange Communication System (PECS) and iPads used as speech generating devices (SGDs), and none have targeted preschoolers. This study compares the relative efficacy of PECS and an iPad/SGD with three preschool-aged children with autism spectrum disorder and limited functional speech who lived in Malta. The study utilized an adapted alternating treatment design embedded in a multiple baseline design, with requesting of reinforcers as the dependent variable. Visual analysis of the results indicated that all participants required more prompted trials and sessions for the iPad/SGD condition. All participants learned a three step navigational sequence on the iPad. Participant preference probes were inconclusive and were not linked to speed of acquisition of requesting skills. Results suggest that both PECS and an iPad could be appropriate for teaching requesting skills to beginning communicators. PMID:26586580

    Potential contributions of environmental chemicals and conditions to the etiology of Autism Spectrum Disorders are the subject of considerable current research and speculation. The present paper describes the results of a study undertaken as part of a larger project devoted to the connection between properties of the indoor environment and asthma and allergy in young Swedish children. The larger project, The Dampness in Buildings and Health (DBH) Study, began in the year 2000 with a questionnaire distributed to parents of all children 1-6 years of age in one Swedish county (DBH-I). A second, follow-up questionnaire (DBH-III) was distributed in 2005. The original survey collected information about the child, the family situation, practices such as smoking, allergic symptoms, type of residence, moisture-related problems, and type of flooring material, which included polyvinyl chloride (PVC). The 2005 survey, based on the same children, now 6-8 years of age, also asked if, during the intervening period, the child had been diagnosed with Autism, Asperger's syndrome, or Tourette's syndrome. From a total of 4779 eligible children, 72 (60 boys, 12 girls) were identified with parentally reported autism spectrum disorder. A random sample of 10 such families confirmed that the diagnoses had been made by medical professionals, in accordance with the Swedish system for monitoring children's health. An analysis of the associations between indoor environmental variables in 2000 as well as other background factors and the ASD diagnosis indicated five statistically significant variables: (1) maternal smoking; (2) male sex; (3) economic problems in the family; (4) condensation on windows, a proxy for low ventilation rate in the home; (5) PVC flooring, especially in the parents' bedroom. In addition, airway symptoms of wheezing and physician-diagnosed asthma in the baseline investigation (2000) were associated with ASD 5 years later. Results from the second phase of the DBH

    To the best of our knowledge, there are no case studies of serotonin syndrome (SS) in patients with autism spectrum disorder. We report the case of a 33-year-old male who presented SS under the combined use of clomipramine and risperidone. More specifically, within 2 days after clomipramine (10 mg/BID-two times a day) was added to risperidone (4 mg/OD-once a day), mirtazapine 45 mg/OD and alprazolam (0,5 mg/TID-three times a day) he began to present mental, neurological and autonomic symptoms. All his psychopathological manifestations and laboratory findings normalized after the above-mentioned drugs' discontinuation, and the administration of supportive medical care and lorazepam 2,5 mg/TID. The diagnosis of serotonin syndrome was challenging due to the relatively low dose of clomipramine, an increase of risperidone which had taken place before clomipramine administration and clinical symptoms which could be attributed to both serotonin and neuroleptic malignant syndrome.

    Hyperkinetic movement disorders represent a heterogeneous group of disorders in which involuntary movements are the prevalent clinical symptoms. The five main categories of hyperkinetic disorders are tremor, dystonia, tics,myoclonus and drug-induced dyskinesia.The severity of hyperkinetic disorders is assessed by all clinicians when they examine a patient; quantifying the severity also provides a means of studying the natural history of a given disorder and the possible effect of new therapeutic interventions. This means that good rating instruments are required in both everyday practice and experimental settings. Unfortunately, the clinical evaluation of these disorders is complicated by the inherent nature and variability over time of involuntary movements. A number of scales have been proposed over the years to study the various hyperkinetic disorders. The aim of this review is to systematically identify all the clinical scales that have been proposed and to classify them according to the criteria developed by the Movement Disorder Society (MDS) task force for rating scales in Parkinson's disease.On the basis of this methodology, a scale may be defined as 'Recommended', 'Suggested' or 'Listed' in decreasing order of value.We found that, although numerous scales aimed at assessing hyperkinetic disorders have been published, their variability in terms of clinimetric properties, availability and effort required to administer them is high. In this evaluation, we identified scales defined as 'Recommended' for the assessment of all forms of hyperkinetic disorders. The situation highlighted by our analysis varies considerably, with several 'Recommended' scales being available for some conditions such as tics or dystonia, but only one being available for myoclonus. This gap needs to be filled by the scientific community through both the development of new clinical tools and there finement of existing ones. PMID:26428309

    Dependent personality disorder (DPD) has evolved from an abstract idea rooted in a historic and psychoanalytic context to a codified diagnosis in the DSM-IV-TR. This comprehensive review paper chronicles the evolution of DPD through each version of the DSM. Major topics relevant to the disorder are also investigated, including gender and cultural considerations, stability and manifestations of DPD across different developmental stages, comorbidity issues, and others. The purpose of this review is to provide a broad yet comprehensive examination of the complex angles of maladaptive dependency and to identify essential next steps in furthering our knowledge of this disorder. The paper concludes with a discussion of shortcomings in the body of research relevant to DPD, along with specific suggestions for improvement in this field of study. PMID:24185092

    2013-01-01

    Background This study examined the efficacy and safety of N-acetylcysteine (NAC) augmentation for treating irritability in children and adolescents with autism spectrum disorders (ASD). Method Forty children and adolescents met diagnostic criteria for ASD according to DSM-IV. They were randomly allocated into one of the two groups of NAC (1200 mg/day)+risperidone or placebo+risperidone. NAC and placebo were administered in the form of effervescent and in two divided doses for 8 weeks. Irritability subscale score of Aberrant Behavior Checklist (ABC) was considered as the main outcome measure. Adverse effects were also checked. Results The mean score of irritability in the NAC+risperidone and placebo+risperidone groups at baseline was 13.2(5.3) and 16.7(7.8), respectively. The scores after 8 weeks were 9.7(4.1) and 15.1(7.8), respectively. Repeated measures of ANOVA showed that there was a significant difference between the two groups after 8 weeks. The most common adverse effects in the NAC+risperidone group were constipation (16.1%), increased appetite (16.1%), fatigue (12.9%), nervousness (12.9%), and daytime drowsiness (12.9%). There was no fatal adverse effect. Conclusions Risperidone plus NAC more than risperidone plus placebo decreased irritability in children and adolescents with ASD. Meanwhile, it did not change the core symptoms of autism. Adverse effects were not common and NAC was generally tolerated well. Trial registration This trial was registered at http://www.irct.ir. The registration number of this trial was IRCT201106103930N6 PMID:23886027

  14. Developmental heterochrony and the evolution of autistic perception, cognition and behavior

    PubMed Central

    2013-01-01

    Background Autism is usually conceptualized as a disorder or disease that involves fundamentally abnormal neurodevelopment. In the present work, the hypothesis that a suite of core autism-related traits may commonly represent simple delays or non-completion of typical childhood developmental trajectories is evaluated. Discussion A comprehensive review of the literature indicates that, with regard to the four phenotypes of (1) restricted interests and repetitive behavior, (2) short-range and long-range structural and functional brain connectivity, (3) global and local visual perception and processing, and (4) the presence of absolute pitch, the differences between autistic individuals and typically developing individuals closely parallel the differences between younger and older children. Summary The results of this study are concordant with a model of ‘developmental heterochrony’, and suggest that evolutionary extension of child development along the human lineage has potentiated and structured genetic risk for autism and the expression of autistic perception, cognition and behavior.

    Objective There is probably a relationship between zinc/cupper concentration in individuals with autism. The present review was written to estimate this probability by using meta-analysis method. Martials & Methods In this meta-analysis of Fixed Effect Model, by searching PubMed, Scopus and Google scholar databases, 11 articles were selected and verified published in 1978 to 2012. I² statistics were calculated to examine heterogeneity. The information was analyzed by R and STATA Ver. 11.2. Results Due to non-uniform measurement methods of Zn/Cu concentrations, the concentration of these elements was measured in various subgroups (plasma, hair and general) in both study cases and controls. There was a significant statistical difference between plasma OR=0.252 (95% CI: -0.001-0.504) and hair OR=0.27(95% CI: 0.059-0.481, P=0.01) concentrations of Zn/Cu statuses between controls and autistic patients. Using a Fixed Effects Model, the overall integration of data from the two groups was significant as risk factor OR=0.31(95% CI:0.16-0.46, P=0.001). Conclusion Significant correlation existed between Zn/Cu levels and the development of autistic disorders in general analysis. Therefore, Zn/Cu levels could be mentioned as a pathogenesis reason of autism spectrum disorders. PMID:26664435

  18. Reduced GABAergic Action in the Autistic Brain.

    2016-01-11

    An imbalance between excitatory/inhibitory neurotransmission has been posited as a central characteristic of the neurobiology of autism [1], inspired in part by the striking prevalence of seizures among individuals with the disorder [2]. Evidence supporting this hypothesis has specifically implicated the signaling pathway of the inhibitory neurotransmitter, γ-aminobutyric acid (GABA), in this putative imbalance: GABA receptor genes have been associated with autism in linkage and copy number variation studies [3-7], fewer GABA receptor subunits have been observed in the post-mortem tissue of autistic individuals [8, 9], and GABAergic signaling is disrupted across heterogeneous mouse models of autism [10]. Yet, empirical evidence supporting this hypothesis in humans is lacking, leaving a gulf between animal and human studies of the condition. Here, we present a direct link between GABA signaling and autistic perceptual symptomatology. We first demonstrate a robust, replicated autistic deficit in binocular rivalry [11], a basic visual function that is thought to rely on the balance of excitation/inhibition in visual cortex [12-15]. Then, using magnetic resonance spectroscopy, we demonstrate a tight linkage between binocular rivalry dynamics in typical participants and both GABA and glutamate levels in the visual cortex. Finally, we show that the link between GABA and binocular rivalry dynamics is completely and specifically absent in autism. These results suggest a disruption in inhibitory signaling in the autistic brain and forge a translational path between animal and human models of the condition. PMID:26711497

    Children with CHARGE syndrome frequently exhibit moderate to severe behavior difficulties, and are often diagnosed with obsessive-compulsive disorder, attention deficit disorder, Tourette syndrome, and autism. Hartshorne and Cypher (2004) surveyed parents of 100 children with CHARGE worldwide and confirmed the prevalence of behaviors that are associated with these disorders. They also found behaviors that could be described as typical of persons who are deafblind. The present study examined whether the autistic-like behaviors of children with CHARGE are more similar to those of children who are deafblind, to those of children who are autistic or are unique to CHARGE. Surveys including the Autism Behavior Checklist (ABC) were mailed to families of 204 children with CHARGE, and 160 usable surveys were returned (78%). Total scores on the ABC for children with CHARGE were significantly different from the norms for those with autism, and those who were deafblind. However, the variance for CHARGE was larger than for the normative groups, and 27.5% of those with CHARGE could be classified as autistic. The pattern of subscale scores for those with CHARGE differed from the other normative groups. PMID:15637726

    The link between parental autistic tendency and anxiety symptoms was studied in 491 Taiwanese couples raising biological children with autism spectrum disorders (ASDs). Parental autistic tendency as measured by Autism Spectrum Quotient (AQ) was associated with anxiety symptoms across all domains. Large effect sizes were found in social phobia and post traumatic stress disorders for both parents, and in general anxiety disorder and agoraphobia for mothers. These associations were irrespective of child's autistic tendency, spouse's AQ scores and the couples' compatibility in their autistic tendency. Perceived family support and parental education moderated the link but not child's autistic severity. Research and clinical implications regarding psychiatric vulnerability of parents of children with ASD were drawn and discussed. PMID:24907095

    Psoriasis is an immune-mediated chronic inflammatory disorder which manifests as dermatologic lesions, and psoriatic arthritis (PsA) in about 30% of cases. Psoriasis is associated with multiple comorbidities including metabolic syndrome, hypertension, diabetes, cardiovascular events, obesity and psychiatric disorders, which can all affect the course of sleep disorders. A systematic review of the literature on the relationship between psoriasis, PsA, and formal sleep disorders identified 33 studies. There is an increased prevalence of obstructive sleep apnea (OSA) with 36%-81.8% prevalence in psoriasis versus 2%-4% in the general population. There was also an increase in the prevalence of restless legs syndrome of 15.1%-18% in psoriasis versus 5%-10% in European and North American samples. The wide variety of insomnia criteria used in studies resulted in an insomnia prevalence of 5.9%-44.8% in psoriasis, which is insufficient to show an elevated prevalence when the general population has a 10% prevalence of chronic insomnia and 30-35% prevalence of transient insomnia. There is evidence that symptoms of insomnia in psoriasis are directly mediated by pruritus and pain. Treatments that decrease the cutaneous symptoms in psoriasis were successful in mitigating insomnia, but did not show improvements in OSA where the relationship with psoriasis is multifactorial.

    There are several unique psychiatric disorders that are likely to present to a dermatologist because of their accompanying skin complaints. Delusions of parasitosis (DP) is a fixed, false belief of parasitic infestation that may lead patients to compulsively self-mutilate while attempting to remove the non-existent parasites. Morgellons disease is a controversial condition characterized by a fixed belief that fibers that are imbedded or extruding from the skin; this condition is likely in the spectrum of DP. Body dysmorphic disorder (BDD) is a preoccupation with an imagined defect in appearance that causes significant distress and is associated with time consuming rituals, isolation, depression, and increased risk of suicide. Olfactory reference syndrome (ORS) is a preoccupation with body odor leading to the stigmata of shame, embarrassment, and social isolation. This brief review examines each of these conditions and their management because any one of them may present to a dermatologist. PMID:18713583

    The study of the pathophysiology of seasonal affective disorder (SAD, also known as winter depression) has historically been intimately linked to investigations into the mechanisms of action of light therapy. This paper reviews the studies on the pathophysiology of SAD with emphasis on circadian, neurotransmitter, and genetic hypotheses. There is substantial evidence for circadian phase shift and serotonergic hypotheses, but conflicting results may indicate that SAD is a biologically heterogeneous condition. Recent progress in defining the molecular mechanisms of the human circadian clock and retinal phototransduction of light will provide important new directions for future studies of the etiology and pathophysiology of SAD.

  12. Efficacy and tolerability of pharmacotherapy options for the treatment of irritability in autistic children.

    PubMed

    Kirino, Eiji

    2014-01-01

    Children with autism have a high rate of irritability and aggressive symptoms. Irritability or self-injurious behavior can result in significant harm to those affected, as well as to marked distress for their families. This paper provides a literature review regarding the efficacy and tolerability of pharmacotherapy for the treatment of irritability in autistic children. Although antipsychotics have not yet been approved for the treatment of autistic children by many countries, they are often used to reduce symptoms of behavioral problems, including irritability, aggression, hyperactivity, and panic. However, among antipsychotics, the Food and Drug Administration has approved only risperidone and aripiprazole to treat irritability in autism. Among atypical antipsychotics, olanzapine and quetiapine are limited in their use for autism spectrum disorders in children because of high incidences of weight gain and sedation. In comparison, aripiprazole and ziprasidone cause less weight gain and sedation. However, potential QTc interval prolongation with ziprasidone has been reported. Contrary to ziprasidone, no changes were evident in the QT interval in any of the trials for aripiprazole. However, head-to-head comparison studies are needed to support that aripiprazole may be a promising drug that can be used to treat irritability in autistic children. On the other hand, risperidone has the greatest amount of evidence supporting it, including randomized controlled trials; thus, its efficacy and tolerability has been established in comparison with other agents. Further studies with risperidone as a control drug are needed. PMID:24932108

  13. Transference and countertransference in the analysis of a child with autistic nuclei.

    PubMed

    Franch, N J

    1996-08-01

    The author stresses the importance of using the countertransference when working with autistic and borderline children, in whom severe disorders of cognitive and emotional development have not permitted the establishment of an internal three-dimensional space whereby emotions can be contained, meaning can be assigned to those emotions and symbols can be formed. She argues that the transference will arise gradually in response to the analyst's countertransference. Great importance is attached to the setting in both its material and psychic aspects, the stability of the former being essential because of the patient's two-dimensional mode of functioning, in which he lacks any representation of space and time. After a review of the theoretical background to the treatment of autistic children with particular reference to the work of Houzel and Tustin and a brief discussion of general aspects of the transference in the light of the views of Freud, Klein and Bion, the author turns to the clinical material proper, presenting vignettes from a number of sessions in the analysis of an autistic boy. These show how she utilises her own emotions, sensations and associations to gain information about the patient's state and, by assigning meaning to these manifestations and communicating it to him, to impart motion to his frozen internal world. The author reports that, after several years of analysis, the patient has introjected a stable object that will lead to healthier development and a sense of security. PMID:8876335

  14. Power and Autistic Traits

    PubMed Central

    Overskeid, Geir

    2016-01-01

    Autistic traits can help people gain and sustain power, and has probably done so throughout history, says the present paper. A number of testable claims follow from this assumption. First, the powerful should have more autistic traits than others – which they do appear to have. Among other things, powerful people, and those with many autistic traits, tend to prefer solitary activities and are often aloof. Moreover, they are often rigid and socially insensitive, low on empathy and with low scores on the trait of agreeableness – and as a rule they do not have many friends. Both groups are also more self-centered than others, more honest, less submissive, more sensitive to slights, and with a stronger tendency to engage in abstract thinking. They tend to behave in bossy or dominant ways, and their moral judgment is more based on rules than on feelings. In addition to experimental evidence, I cite biographies showing that a surprising number of presidents, prime ministers and other powerful people seem to have had traits like those in question – and interestingly, in animals, leaders are often rigid and insensitive to group members’ needs and feelings, mostly acting the way they are themselves inclined to, not responding much to others. Problem solving is important in leadership, and people with many autistic traits appear often to be better thinkers than typical subjects with similar IQs. However, these and other congruities could be coincidences. Hence the question of whether traits the two groups have in common also have a common cause constitutes a strong test of the paper’s thesis – and a common cause does appear to exist, in the form of testosterone’s effects on the central nervous system. Finally, there is evidence that, other things equal, powerful men have more reproductive success than others. If men wielding power do indeed have more autistic traits than those less powerful, this will lead to, other things equal, such traits becoming more

    The study of schizotypal personality disorder (SPD) is important clinically, as it is understudied, challenging to treat, often under-recognized or misdiagnosed, and associated with significant functional impairment. SPD also represents an intermediate schizophrenia-spectrum phenotype, and therefore, can provide a better understanding of the genetics, pathogenesis, and treatment of related psychotic illnesses. In this review we discuss recent findings of SPD related to epidemiology and functional impairment; heritability and genetics; working memory and cognitive impairments; social-affective disturbances; and neurobiology. Additionally, we examine the challenges associated with treating patients with SPD, as well as clinical recommendations. Finally, we address future directions and areas in need of further exploration. PMID:24828284

    Homocysteine (Hcy) is a sulfur-containing amino acid that is generated during methionine metabolism. It has a physiologic role in DNA metabolism via methylation, a process governed by the presentation of folate, and vitamins B6 and B12. Physiologic Hcy levels are determined primarily by dietary intake and vitamin status. Elevated plasma levels of Hcy (eHcy) can be caused by deficiency of either vitamin B12 or folate, or a combination thereof. Certain genetic factors also cause eHcy, such as C667T substitution of the gene encoding methylenetetrahydrofolate reductase. eHcy has been observed in several medical conditions, such as cardiovascular disorders, atherosclerosis, myocardial infarction, stroke, minimal cognitive impairment, dementia, Parkinson's disease, multiple sclerosis, epilepsy, and eclampsia. There is evidence from laboratory and clinical studies that Hcy, and especially eHcy, exerts direct toxic effects on both the vascular and nervous systems. This article provides a review of the current literature on the possible roles of eHcy relevant to various neurologic disorders. PMID:25324876

    Persons with autistic traits may be at elevated risk for interpersonal victimization across the life course. Children with high levels of autistic traits may be targeted for abuse, and deficits in social awareness may increase risk of interpersonal victimization. Additionally, persons with autistic traits may be at elevated risk of posttraumatic stress disorder (PTSD) symptoms subsequent to trauma. We examined retrospectively reported prevalence of childhood abuse, trauma victimization and PTSD symptoms by autistic traits among adult women in a population-based longitudinal cohort, the Nurses' Health Study II (N=1,077). Autistic traits were measured by the 65-item Social Responsiveness Scale. We estimated odds ratios (OR) for childhood sexual and physical/emotional abuse and PTSD symptoms by quintiles of autistic traits. We examined possible mediation of PTSD risk by abuse and trauma type. Women in the highest versus lowest quintile of autistic traits were more likely to have been sexually abused (40.1% versus 26.7%), physically/emotionally abused (23.9% versus 14.3%), mugged (17.1% versus 10.1%), pressured into sexual contact (25.4% versus 15.6%) and have high PTSD symptoms (10.7% versus 4.5%). Odds of PTSD were elevated in women in the top three quintiles of autistic traits compared with the reference group (OR range=1.4 to 1.9). Childhood abuse exposure partly accounted for elevated risk of PTSD in women with autistic traits. We identify for the first time an association between autistic traits, childhood abuse, trauma victimization, and PTSD. Levels of autistic traits that are highly prevalent in the general population are associated with abuse, trauma and PTSD. PMID:25957197

    The 1980s were a decade of advancement in the knowledge of anxiety disorders in children and adolescents; this sets the stage for research achievements in the 1990s. This review examines the anxiety disorders of childhood and adolescence (separation anxiety disorder, overanxious disorder, and avoidant disorder), including prevalence rates, demographic profiles, comparisons of clinical presentations in different developmental age groups, and comorbidity patterns. Fears and simple phobias, obsessive-compulsive disorder, post-traumatic stress disorder, and panic disorder in children and adolescents are also evaluated. The controversy of whether panic attacks occur in prepubertal children is addressed. A brief review of behavioral and pharmacological treatment studies is included. Future directions for research are suggested. PMID:1890084

    Studies suggest associations between childhood autistic traits and adolescent psychotic experiences. However, recent research suggests that a general neuropsychiatric problems factor predicts adverse outcomes better than specific diagnostic entities. To examine if the alleged association between autistic traits and psychotic experiences could rather be explained by a general neuropsychiatric problems factor comprising symptoms of ADHD, tic disorder, developmental coordination disorder, and learning disorder, we conducted a prospective cohort study based on the Child and Adolescent Twin Study in Sweden. In addition, we examined the genetic and environmental influences on the associations. A total of 9,282 twins with data on childhood autistic traits and other neuropsychiatric problems, and follow-up data on psychotic experiences at ages 15 and/or 18 years were included. First, psychotic experiences were regressed on autistic traits and second, the general neuropsychiatric problems factor was added to the model. Auditory hallucinations were analyzed separately from the other psychotic experiences. Finally, twin analyses were employed to disentangle genetic from environmental influences in the observed associations. Replicating prior research, significant associations were found between autistic traits in childhood and auditory hallucinations at ages 15 and 18. However, after controlling for the general neuropsychiatric problems factor, the associations between autistic traits and auditory hallucinations disappeared, whereas the association between the general neuropsychiatric problems factor and auditory hallucinations persisted after controlling for autistic traits. Twin analyses revealed that the association between the general neuropsychiatric problems factor and auditory hallucinations was driven by shared genetic influences. © 2015 Wiley Periodicals, Inc.

  10. The epidemiology of anxiety disorders: a review

    PubMed Central

    2003-01-01

    Epidemiological studies show that anxiety disorders are highly prevalent and an important cause of functional impairment; they constitute the most frequent menial disorders in the community. Phobias are the most common with the highest rates for simple phobia and agoraphobia. Panic disorder (PD) and obsessive-compulsive disorder (OCD) are less frequent (2% lifetime prevalence), and there are discordant results for social phobia (SP) (2%-16%) and generalized anxiety disorder (GAD) (3%-30%). These studies underline the importance of an accurate definition of disorders using unambiguous diagnostic and assessment criteria. The boundaries between anxiety disorders are often ill defined and cases may vary widely according to the definition applied. Simple phobia, agoraphobia, and GAD are more common in vmrnen, while there is no gender différence for SP, PD, and OCD, Anxiety disorders are more common in separated, divorced, and widowed subjects; their prevalence is highest in subjects aged 25 to 44 years and lowest in subjects aged >65 years. The age of onset of the different types of anxiety disorders varies widely: phobic disorders begin early in life, whereas PD occurs in young adulthood. Clinical - rather than epidemiological - studies have examined risk factors such as life events, childhood experiences, and familial factors. Anxiety disorders have a chronic and persistent course, and are frequently comorbid with other anxiety disorders, depressive disorders, and substance abuse. Anxiety disorders most frequently precede depressive disorders or substance abuse, Comorbid diagnoses may influence risk factors like functional impairment and quality of life. It remains unclear whether certain anxiety disorders (eg, PD) are risk factors for suicide. The comorbidity of anxiety disorders has important implications for assessment and treatment and the risk factors should be explored. The etiology, natural history, and outcome of these disorders need to be further addressed

  11. Antipsychotic Management of Schizoaffective Disorder: A Review.

    Lindenmayer, Jean-Pierre; Kaur, Amandeep

    2016-04-01

    Schizoaffective disorder (SAD) is an incapacitating illness that presents clinicians with challenges in terms of both its diagnosis and its psychopharmacological management. Most studies conducted on the psychopharmacological treatment of SAD also include patients with schizophrenia or other psychotic illnesses, thereby providing an unspecific view to the clinician as to the best way of treating patients with SAD. The objective of this article is to review studies on evidence-based treatment of patients with SAD. We conducted a systematic literature search in MEDLINE/PubMed for full-text studies in the English language using the terms 'Schizoaffective and treatment' or 'antipsychotic schizoaffective'. Our review found relatively few studies with either an active comparator or placebo that examined the efficacy of antipsychotics for patients with SAD without an admixture of patients with schizophrenia. Only oral paliperidone extended release (ER), paliperidone long-acting injection (LAI), and risperidone have been shown to be effective and safe in reducing psychotic as well as affective components in acutely ill SAD patients in controlled studies. Paliperidone ER and LAI have also been shown to be efficacious in the maintenance treatment phase of SAD patients. While no supportive data exist, it is possible that other atypical antipsychotics may have similar efficacy to the two mentioned above. We conclude with a number of research recommendations for the study of treatment options for patients with SAD. First, there is a need for studies with patients specifically diagnosed with SAD for both the acute and the maintenance phase. The sample size needs to be adequate to allow a primary analysis of efficacy and to allow for analysis of the SAD subtypes: depressed and bipolar. Another recommendation is the need for studies of patients with SAD stratified into patients with and without mood stabilizers or antidepressants to allow the examination of the adjunctive role of

    Children with deafness who are also on the autistic spectrum are a group with complex support needs. Carers worry about their ability to communicate with them, and are often uncertain about what constitutes 'good' communication in this context. This paper analyses the use of a therapeutic intervention, Video Interaction Guidance (VIG), which originates in developmental psychology and focuses on the relational foundations of communication. We draw on a single case using an ethnomethodological/conversation analytic framework, and in particular Goodwin's (1994) work on 'professional vision', to show how the ability to see 'success' is a socially situated activity. Since what counts as success in this setting is often far removed from everyday ideas of good communication, how guiders facilitate particular 'ways of seeing' are critical for both the support of carers and the impact of the intervention. We argue that this work has implications in three areas: for the practice of VIG itself; for the role of qualitative, interactional research addressing the way in which interaction-based interventions are protocolised, enacted and assessed; and for the way in which expertise is conceptualised in professional/client interactions in health and social care.

    Objective: Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder frequently co-occur. Several studies show increased risk of substance use disorders in ADHD, yet there is limited information related to how ADHD symptoms, autistic traits, and their combined effects are associated with nicotine, alcohol, and cannabis use and use disorders in the general population. Method: Cross-sectional interview and self-report questionnaire data from 3,080 young adult Australian twins (mean age 31.9 years) were used to assess ADHD symptoms, autistic traits, substance use, and substance use disorders. Substance use disorders—based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria—were assessed in the full sample as well as in those who reported substance use. Logistic regression analyses were used for comparing the associations between ADHD symptoms, autistic traits, substance use, and substance misuse after conduct disorder, sex, age, and zygosity were controlled for. Results: Greater ADHD symptoms and autistic traits scores were associated with elevated levels of regular smoking; cannabis use; and nicotine, alcohol, and cannabis use disorders, even after conduct disorder was adjusted for. In contrast, for alcohol use, those with high autistic traits scores were less likely to report drinking to intoxication. However, upon initiation, and similar to the findings for nicotine and cannabis, they were at elevated risk for developing alcohol dependence. Conclusions: Increased liability to ADHD and elevated autistic traits scores were associated with substance use and misuse, with the exception of alcohol use. Given the social underpinnings of drinking, persons with autistic traits may be less likely to engage in it; however, upon engagement in drinking, their vulnerability to alcohol dependence is elevated.

    Post-traumatic stress disorder is highly prevalent among individuals who suffer from opioid use disorder. Compared to individuals with opioid use disorder alone, those with post-traumatic stress disorder have a worse course of illness, occupational functioning, and physical health. The neurobiological pathways underlying each disorder overlap substantially, and there are multiple pathways through which these disorders may interact. This narrative review explores evidence underpinning 3 explanatory perspectives on comorbid post-traumatic stress disorder and opioid use disorder: The opioid susceptibility model (a.k.a.: the Self-Medication Hypothesis), the post-traumatic stress disorder susceptibility model, and the common factors model. Diagnostic implications, treatment implications, and directions for future research are discussed. PMID:27010975

  2. Sexual abuse and eating disorders: a review.

    PubMed

    Connors, M E; Morse, W

    1993-01-01

    Studies investigating a possible relationship between sexual abuse and eating disorders have reported highly discrepant results. Some variability can be accounted for by methodological issues including diagnostic criteria, study design, and assessment techniques. The heterogeneity of an eating disordered population, especially regarding the comorbidity of eating pathology and personality disorder, is also a factor. Overall results suggest that around 30% of eating disordered patients have been sexually abused in childhood, a figure that is relatively comparable to rates found in normal populations. For some patients there may be a direct link between sexual trauma and eating pathology, but in general sexual abuse is best considered a risk factor in a biopsychosocial etiological model of eating disorders. Complex associations between trauma, self-regulatory deficits, and psychopathology require further research. PMID:8477269

    2013-01-01

    Bipolar disorder and alcohol use disorder represent a significant comorbid population, which is significantly worse than either diagnosis alone in presentation, duration, co-morbidity, cost, suicide rate, and poor response to treatment. They share some common characteristics in relation to genetic background, neuroimaging findings, and some biochemical findings. They can be treated with separate care, or ideally some form of integrated care. There are a number of pharmacotherapy trials, and psychotherapy trials that can aid programme development. Post-treatment prognosis can be influenced by a number of factors including early abstinence, baseline low anxiety, engagement with an aftercare programme and female gender. The future development of novel therapies relies upon increased psychiatric and medical awareness of the co-morbidity, and further research into novel therapies for the comorbid group. PMID:22983943

    2004-04-01

    Considerable clinical and experimental evidence now supports the idea that deficiencies or imbalances in certain highly unsaturated fatty acids may contribute to a range of common developmental disorders including ADHD, dyslexia, dyspraxia and autistic spectrum disorders (ASD). Definitive evidence of a causal contribution, however, can only come from intervention studies in the form of randomised, double-blind, placebo-controlled trials. Published studies of this kind are still fairly few in number, and mainly involve the diagnostic categories of ADHD and dyslexia, although other trials involving individuals with dyspraxia or ASD are in progress. The main findings to date from such studies are reviewed and evaluated here with the primary aim of guiding future research, although given that fatty acid supplementation for these conditions is already being adopted in many quarters, it is hoped that some of the information provided may also help to inform clinical practice.

    PubMed Central

    2012-01-01

    Background Glutathione has a wide range of functions; it is an endogenous anti-oxidant and plays a key role in the maintenance of intracellular redox balance and detoxification of xenobiotics. Several studies have indicated that children with autism spectrum disorders may have altered glutathione metabolism which could play a key role in the condition. Methods A systematic literature review and meta-analysis was conducted of studies examining metabolites, interventions and/or genes of the glutathione metabolism pathways i.e. the γ-glutamyl cycle and trans-sulphuration pathway in autism spectrum disorders. Results Thirty nine studies were included in the review comprising an in vitro study, thirty two metabolite and/or co-factor studies, six intervention studies and six studies with genetic data as well as eight studies examining enzyme activity. Conclusions The review found evidence for the involvement of the γ-glutamyl cycle and trans-sulphuration pathway in autistic disorder is sufficiently consistent, particularly with respect to the glutathione redox ratio, to warrant further investigation to determine the significance in relation to clinical outcomes. Large, well designed intervention studies that link metabolites, cofactors and genes of the γ-glutamyl cycle and trans-sulphuration pathway with objective behavioural outcomes in children with autism spectrum disorders are required. Future risk factor analysis should include consideration of multiple nutritional status and metabolite biomarkers of pathways linked with the γ-glutamyl cycle and the interaction of genotype in relation to these factors.

    2015-01-01

    Objective: Gabapentin is commonly used off-label in the treatment of psychiatric disorders with success, failure, and controversy. A systematic review of the literature was performed to elucidate the evidence for clinical benefit of gabapentin in psychiatric disorders. Data sources: Bibliographic reference searches for gabapentin use in psychiatric disorders were performed in PubMed and Ovid MEDLINE search engines with no language restrictions from January 1, 1983, to October 1, 2014, excluding nonhuman studies. For psychiatric references, the keywords bipolar, depression, anxiety, mood, posttraumatic stress disorder (posttraumatic stress disorder and PTSD), obsessive-compulsive disorder (obsessive-compulsive disorder and OCD), alcohol (abuse, dependence, withdraw), drug (abuse, dependence, withdraw), opioid (abuse, dependence, withdraw), cocaine (abuse, dependence, withdraw), and amphetamine (abuse, dependence, withdraw) were crossed with gabapentin OR neurontin. Study selection and data extraction: The resulting 988 abstracts were read by 2 reviewers; references were excluded if gabapentin was not a study compound or psychiatric symptoms were not studied. The resulting references were subsequently read, reviewed, and analyzed; 219 pertinent to gabapentin use in psychiatric disorders were retained. Only 34 clinical trials investigating psychiatric disorders contained quality of evidence level II-2 or higher. Results: Gabapentin may have benefit for some anxiety disorders, although there are no studies for generalized anxiety disorder. Gabapentin has less likely benefit adjunctively for bipolar disorder. Gabapentin has clearer efficacy for alcohol craving and withdrawal symptoms and may have a role in adjunctive treatment of opioid dependence. There is no clear evidence for gabapentin therapy in depression, PTSD prevention, OCD, or other types of substance abuse. Limitations of available data include variation in dosing between studies, gabapentin as monotherapy or

    Personality disorders have been associated with a wide swath of adverse health outcomes and correspondingly high costs to healthcare systems. To date, however, there has not been a systematic review of the literature on health conditions among individuals with personality disorders. The primary aim of this article is to review research documenting the associations between personality disorders and health conditions. A systematic review of the literature revealed 78 unique empirical English-language peer-reviewed articles examining the association of personality disorders and health outcomes over the past 15 years. Specifically, we reviewed research examining the association of personality disorders with sleep disturbance, obesity, pain conditions, and other chronic health conditions. In addition, we evaluated research on candidate mechanisms underlying health problems in personality disorders and potential treatments for such disorders. Results underscore numerous deleterious health outcomes associated with PD features and PD diagnoses, and suggest potential biological and behavioural factors that may account for these relations. Guidelines for future research in this area are discussed. PMID:26456998

    Excessive use of alcohol has been identified as a major contributor to the global burden of disease. Excessive use of alcohol is a component cause of more than 200 disease and injury conditions. Alcohol use has been associated with increased morbidity and mortality across all regions of the world including South-East Asia. Epidemiological as well as clinic-based studies from Western countries have reported a high prevalence of co-occurrence of alcohol use disorder and psychiatric disorders. The research has established the clinical relevance of this comorbidity as it is often associated with poor treatment outcome, severe illness course, and high service utilization. Understandably, dual disorders in from of alcohol use disorders and psychiatric disorders present diagnostic and management challenge. The current article is aimed to review systematically the published Indian literature on comorbid alcohol use disorders and psychiatric disorders. PMID:27011396

    2013-01-01

    Radiosurgery for psychiatric disorders has been performed for more than 50 years. The use of deep brain stimulation has recently been expanded to the investigational treatment of specific psychiatric disorders. A literature review of past studies incorporating radiosurgical stereotactic lesions for psychiatric disorders was performed to provide historic context and possible guidance for current and future attempts at treating psychiatric disorders, especially by gamma capsulotomy. The anatomic target localization, dose selection, and the outcome of the radiosurgical procedures were reviewed, and the evolutions of lesioning strategies were analyzed with particular emphasis on the dose selection. Large-scale prospective studies with strict inclusion and well-defined, objective outcome criteria are necessary for defining the role of radiosurgery for the treatment of psychiatric disorders.

    Eating disorders are a major challenge for health professionals, with many patients receiving ineffective care due to underdiagnosis or poor compliance with treatment. The incidence of eating disorders is increasing worldwide, producing an increasing burden on healthcare systems, and they most often affect young patients, with significant long-term complications. The effects of long-term malnutrition manifest in almost every organ system, and many can be detected radiologically, even without overt clinical findings. Musculoskeletal complications including osteoporosis result in a high incidence of insufficiency fractures, with long-term implications for bone health and growth, while respiratory complications are often recognized late due to disordered physiologic responses to infection. Gastrointestinal complications are numerous and in extreme cases may result in fatal outcomes after acute gastric dilatation and rupture subsequent to binge eating. In patients with severely disordered eating, in particular anorexia nervosa, marked derangement of electrolyte levels may result in refeeding syndrome, which requires emergent management. Recognition of such complications is critical to effective patient care and requires radiologists to be aware of the spectrum of imaging abnormalities that may be seen. Since many patients are reluctant to disclose their underlying condition, radiologists also play a critical role in identifying previously undiagnosed eating disorders. PMID:23842978

    2014-02-01

    Sex is an integral part of the basic needs of an individual. However, Asian populations have had a conservative attitude towards discussing and expressing their sexual concerns to the clinician. Consequently, very limited research on sexuality-related issues has been done on these populations. Many of the biological and socio-cultural factors are different for Asians and Asian migrants to the West, when compared to the native Western population, and this requires dedicated research. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders 5th Edition) has made the classification of sexual dysfunctions gender-specific and has introduced the concepts of 'gender dysphoria' and 'paraphilic disorders' (distinct from paraphilias); it has removed subtypes based on sexual orientation. These changes will have a definite impact on our understanding of sexual dysfunctions and related disorders in the Asian populations. PMID:24524717

  6. Sleep disorders of early childhood: a review.

    PubMed

    Benhamou, I

    2000-01-01

    Night awakening and refusal to go to sleep are common problems during the first three years of life, comprising 6-30% of children in the general population. The organization and regulation of child sleep is thought to be closely related to his mode of attachment to his mother. Sleep aids (pacifier, teddy bear, etc.) during the night seem to reduce the occurrence of sleep disorders whereas prolonged breastfeeding and co-sleep with the parents interfere with the normal development of sleep. During the preschool years, the main issue affecting sleep is the ability of parents to set firm limits while respecting the sense of autonomy of the child. Sleep disorders are considered to be more common among physically and mentally handicapped children. Children with a difficult temperament sleep less than those with an easy one. A clear association is found between sleep patterns and psychopathology of the mother probably due to emotional unavailability and inappropriate behavior. Evaluation of the disorder should follow medical examination. It should take place in the presence of the child in order to view the real interaction as well as given information about the reported interaction between the child and his mother. Therapeutic interventions in cases of early childhood sleep disorders can be behavioral or psychodynamic and are advised to be focused and brief, unless there is psychopathology in the parents.

  7. Skeletal disorders in the fowl: a review.

    PubMed

    Thorp, B H

    1994-06-01

    Selection pressure for production traits in modern lines of poultry has placed increasing demands on skeletal integrity. Disruption of the normal process of skeletal growth and homeostasis results in bone diseases that are manifest throughout the modern poultry industry. Bone conditions in poultry can be grouped under three headings based on the age and type of fowls affected, and are indicative of the genetic and production stresses applied to the skeleton. In broilers during growth it is primarily pathologies of the growth plate that lead to most skeletal disorders. In broiler and turkey breeding stock the progressive degeneration of the articular cartilage results in osteoarthrosis, lameness and a consequential loss of reproductive performance. In laying hens bone fragility is most frequently the result of osteoporosis. Before attempting to determine the aetiology of a skeletal disorder an accurate diagnosis must be made. Only then can short- and long-term strategies be developed for the prevention and control of skeletal disorders. Diagnosis requires gross and histological examination, and also dietary, environmental and management analyses. The pathology often reflects lesions initiated when the bird was considerably younger and analyses must extend to assessing the factors prevalent during the initiation of lesions. Current studies are furthering the understanding of the aetiopathogenesis of avian skeletal disorders. For example, structural bone loss at the onset of follicular activity before egg-laying is pivotal to the development of osteoporosis in layers and deficiencies in growth factor expression are integral to the development of tibial dyschondroplasia.

    2016-01-01

    Skin disorders, usually neglected and frequently underdiagnosed among diabetic patients, are common complications and encounter a broad spectrum of disorders in both type 1 and type 2 diabetes mellitus (DM)-e.g. cutaneous infection, dry skin, pruritus. Skin disorders are highly associated with increased risk of important outcomes, such as skin lesions, ulcerations and diabetic foot, which can lead to major complications and revolve around multifactorial factors besides hyperglycemia and advanced glycation end products. Although diabetic's skin disorders are consistent in the literature, there is limited data regarding early-stage skin disorders in DM patients. Disease control, early-stage treatment (e.g. skin hydration, orthotic devices) and awareness can reduce morbidity of DM patients. Thus, better understanding of the burden of skin disorders in DM patients may raise awareness on prevention and management. Therefore, the aim of this study is to perform a literature review to evaluate the main clinical characteristics and complications of skin disorders in diabetic's patients. Additionally, physiopathology early-stage skin disorders and dermocosmetic management were also reviewed. PMID:27583022

    Attention deficit disorder (ADD) in adolescents has received scant attention when compared with that given to children. With or without hyperactivity, ADD does not disappear at puberty and is an important factor in scholastic and social failure in adolescents. As a condition associated with decreased metabolism in the premotor and prefrontal superior cerebral cortex, ADD in adolescents responds well to treatment with stimulants, tricyclic antidepressants and monoamine oxidase inhibitors. Nonpharmacologic modalities such as behavior modification, individual and family therapy, and cognitive therapy are useful adjuncts to psychopharmacologic management. Without effective treatment, ADD often results in increased risk of trauma, substance abuse and conduct and affective disorders during adolescence, and marital disharmony, family dysfunction, divorce, and incarceration in adulthood. Properly treated with medication and counseling, adolescents with ADD succeed as well as their peers. PMID:7779826

    The treatment of bipolar disorders is a demanding task involving patients, therapists and relatives. As bipolar disorders are associated to multiple psychosocial disturbances, the management of a bipolar disease should focus on psychosocial interventions. Despite an exploding literature on this topic, psychopharmacological interventions applied as a monotherapy have shown unsatisfactory outcomes. In order to enhance outcome, psychotherapy, such as cognitive behavioural therapy (CBT), psychoeducation, a modified form of interpersonal psychotherapy (IPSRT) or family focussed psychotherapy (FFT) were investigated. When used in conjunction with pharmacotherapy, these interventions may prolong time to relapse, reduce symptom severity, and increase medication adherence. These combinations are currently considered being the golden standard in the treatment of bipolar disorders. Psychotherapeutic interventions as an add-on strategy exert better effects when patients are euthymic at entry. Prevention of manic episodes seems to be more successful as compared to the prevention of depressive episodes. There are currently no hints for a method specific efficacy. Efficacy of psychoeducation seems to be rather short lived. Currently not yet evaluated booster-sessions might help. More data are needed in order to identify patients with a putative good response to psychotherapeutic interventions. PMID:17640496

    2013-01-01

    Autistic individuals typically excel on spatial tests that measure abstract reasoning, such as the Block Design subtest on intelligence test batteries and the Raven's Progressive Matrices nonverbal test of intelligence. Such well-replicated findings suggest that abstract spatial processing is a relative and perhaps absolute strength of autistic individuals. However, previous studies have not systematically varied reasoning level--concrete vs. abstract--and test domain--spatial vs. numerical vs. verbal, which the current study did. Autistic participants (N = 72) and non-autistic participants (N = 72) completed a battery of 12 tests that varied by reasoning level (concrete vs. abstract) and domain (spatial vs. numerical vs. verbal). Autistic participants outperformed non-autistic participants on abstract spatial tests. Non-autistic participants did not outperform autistic participants on any of the three domains (spatial, numerical, and verbal) or at either of the two reasoning levels (concrete and abstract), suggesting similarity in abilities between autistic and non-autistic individuals, with abstract spatial reasoning as an autistic strength.

    Pregnancy and the postpartum period are recognized as times of vulnerability to mood disorders, including postpartum depression and psychosis. Recently, changes in sleep physiology and sleep deprivation have been proposed as having roles in perinatal psychiatric disorders. In this article we review what is known about changes in sleep physiology and behaviour during the perinatal period, with a focus on the relations between sleep and postpartum “blues,” depression and psychosis and on sleep-based interventions for the treatment and prevention of perinatal mood disorders. The interaction between sleep and perinatal mood disorders is significant, but evidence-based research in this field is limited. Studies that measure both sleep and mood during the perinatal period, particularly those that employ objective measurement tools such as polysomnography and actigraphy, will provide important information about the causes, prevention and treatment of perinatal mood disorders.

    2014-01-01

    Objective: International and societal conflicts and natural disasters can leave physical and mental scars in people who are directly affected by these traumatic experiences. Posttraumatic stress disorder (PTSD) is the clinical manifestation of these experiences in the form of re-experiencing the trauma, avoidance of trauma-related stimuli, and persistent symptoms of hyperarousal. There is growing evidence that sleep disruption that occurs following trauma exposure may in fact contribute to the pathophysiology of PTSD and poor clinical outcomes. The purpose of this review is to highlight the importance of recognition and management of sleep disorders in patients with PTSD. Data Sources: English-language, adult research studies published between 1985 and April 2014 were identified via the PubMed database. The search terms used were PTSD AND sleep disorders. Study Selection: The search identified 792 original and review articles. Of these, 53 articles that discussed or researched sleep disorders in PTSD were selected. Fourteen randomized controlled trials of therapy for PTSD are included in this review. Results: Impaired sleep is a common complaint mainly in the form of nightmares and insomnia among people with PTSD. Sleep apnea and periodic limb movement disorder are particularly prevalent in patients with PTSD and, yet, remain unrecognized. Although selective serotonin reuptake inhibitors are effective in improving PTSD global symptoms, they have a variable and modest effect on sleep disorder symptoms. Cognitive-behavioral treatment targeted to sleep and/or the use of the centrally acting selective α1 antagonist prazosin have been more successful in treating insomnia and nightmares in PTSD than other classes of medications. In view of the high occurrence of sleep apnea and periodic leg movement disorder, a thorough sleep evaluation and treatment are warranted. Conclusions: Patients with PTSD have a high prevalence of sleep disorders and should be queried for

  16. Alexithymia and eating disorders: a critical review of the literature

    PubMed Central

    2013-01-01

    Alexithymia is characterized by difficulties identifying feelings and differentiating between feelings and bodily sensations, difficulties communicating feelings, and a concrete cognitive style focused on the external environment. Individuals with eating disorders have elevated levels of alexithymia, particularly difficulties identifying and describing their feelings. A number of theoretical models have suggested that individuals with eating disorders may find emotions unacceptable and/or frightening and may use their eating disorder symptoms (i.e., restricting food intake, bingeing, and/or purging) as a way to avoid or cope with their feelings. The current critical review synthesizes the literature on alexithymia and eating disorders and examines alexithymia levels across eating disorders (i.e., anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified), the role of alexithymia in binge eating disorder, and the influence of alexithymia on the development of eating disorders as well as treatment outcome. The clinical implications of the research conducted to date and directions for future research are discussed. PMID:24999402

    PubMed

    Cuijpers, Pim; Schoevers, Robert A

    2004-12-01

    Several factors have been proposed to explain the relationship between excess mortality and depressive disorders. These include mechanisms such as increased suicide rates, hazardous health behavior (smoking, alcohol use, unhealthy eating), psychologic reactions to developing a medical illness, biological dysregulations (hyperactivity of the hypothalamic pituitary adrenal, neuro-immune dysregulation, sympathoadrenergic dysregulation), and noncompliance with medical treatment. The evidence supporting the role of each of these mechanisms in excess mortality varies considerably. The causal direction in most of the mechanisms is not clear. It is possible that the explanatory factors, such as smoking, compliance, or biological mechanisms, cause depression, or that depression causes these factors, or that both are explained by a third, underlying factor. We will summarize the evidence supporting these mechanisms, and propose options for possible interventions aimed at reducing the increased risk of dying. PMID:15538991

    Anorexia nervosa and bulimia nervosa are prevalent illnesses affecting between 1% and 10% of adolescent and college age women. Developmental, family dynamic, and biologic factors are all important in the cause of this disorder. Anorexia nervosa is diagnosed when a person refuses to maintain his or her body weight over a minimal normal weight for age and height, such as 15% below that expected, has an intense fear of gaining weight, has a disturbed body image, and, in women, has primary or secondary amenorrhea. A diagnosis of bulimia nervosa is made when a person has recurrent episodes of binge eating, a feeling of lack of control over behavior during binges, regular use of self-induced vomiting, laxatives, diuretics, strict dieting, or vigorous exercise to prevent weight gain, a minimum of 2 binge episodes a week for at least 3 months, and persistent overconcern with body shape and weight. Patients with eating disorders are usually secretive and often come to the attention of physicians only at the insistence of others. Practitioners also should be alert for medical complications including hypothermia, edema, hypotension, bradycardia, infertility, and osteoporosis in patients with anorexia nervosa and fluid or electrolyte imbalance, hyperamylasemia, gastritis, esophagitis, gastric dilation, edema, dental erosion, swollen parotid glands, and gingivitis in patients with bulimia nervosa. Treatment involves combining individual, behavioral, group, and family therapy with, possibly, psychopharmaceuticals. Primary care professionals are frequently the first to evaluate these patients, and their encouragement and support may help patients accept treatment. The treatment proceeds most smoothly if the primary care physician and psychiatrist work collaboratively with clear and frequent communication. PMID:1475950

    2012-01-01

    Objective To review the past 10 years of research in child language or communication disorders, which are highly prevalent in the general population and comorbid with childhood psychiatric disorders. Method A literature search of 3 major databases was conducted. The child language literature, describing the domains of language development—phonology, grammar, semantics, and pragmatics—is reviewed. Results Disorders of grammar, semantics, and pragmatics, but not phonology, overlap significantly with childhood psychiatric disorders. Receptive language disorders have emerged as high-risk indicators, often undiagnosed. Language disorders and delays are psychiatric risk factors and have implications for evaluation, therapy, and research. However, they are often undiagnosed in child mental health and community settings. The research has focused mostly on monolingual English-speaking children. Conclusion Awareness of basic child language development, delay, and deviance is crucial for the practicing child and adolescent psychiatrist, who must diagnose and refer relevant cases for treatment and remediation. Future research needs to address the growing language diversity of our clinical populations. PMID:10673823

    In the 3 decades since Liebowitz's review of 'a neglected anxiety disorder,' controversy and challenges have remained in the study of social anxiety disorder (SAD). This review examines evidence around the classification and subtyping of SAD, focusing on generalized SAD. Substantial discrepancies and variation in definition, epidemiology, assessment, and treatment of generalized SAD exist as the international literature on it has grown. In East Asian cultures in particular, study of taijin kyofusho has been important to a broadened conceptualization of SAD into generalized SAD. Despite important progress with biological and other studies, many challenges in the understanding of generalized SAD will remain in the years to come. PMID:26121185

  8. The relationship between perfectionism, eating disorders and athletes: a review.

    PubMed

    Forsberg, S; Lock, J

    2006-12-01

    Perfectionism is a potentially maladaptive personality trait implicated in a number of psychopathologies. As our understanding of the construct perfectionism has shifted from more unidimensionally focused conceptualizations to multidimensional ones, our ability to assess its bearing on various disorders has grown. One particular area in which perfectionism appears to play an important role is among eating disorder patients. The personalities of both those with anorexia nervosa (AN) and bulimia nervosa (BN) are thought to be intrinsically perfectionistic, which suggests a need to understand the role perfectionism plays in the development, course and outcome of these disorders. There is also an increased focus on perfectionism among athletes and its relationship to the higher prevalence of eating disorders in this group. With the institution of Title IX in the United States (which prohibited sex discrimination in higher educational settings) the participation of women in various sports has increased exponentially and with it concerns about their well-being in a milieu where a risk for menstrual irregularities, osteoporosis and eating disorders (the female athlete triad) are common. However, conflicting data suggests that athletics may be a protective factor in the development of eating disorders on the one hand, or it may be a risk factor on the other. Thus, it has become important to examine other variables, such as perfectionism, that may influence the outcome, one way or another. This review examines the current evidence about the relations between perfectionism, athletics and eating disorders. PMID:17093375

    High proportions of autistic children suffer from gastrointestinal (GI) disorders, implying a link between autism and abnormalities in gut microbial functions. Increasing evidence from recent high-throughput sequencing analyses indicates that disturbances in composition and diversity of gut microbiome are associated with various disease conditions. However, microbiome-level studies on autism are limited and mostly focused on pathogenic bacteria. Therefore, here we aimed to define systemic changes in gut microbiome associated with autism and autism-related GI problems. We recruited 20 neurotypical and 20 autistic children accompanied by a survey of both autistic severity and GI symptoms. By pyrosequencing the V2/V3 regions in bacterial 16S rDNA from fecal DNA samples, we compared gut microbiomes of GI symptom-free neurotypical children with those of autistic children mostly presenting GI symptoms. Unexpectedly, the presence of autistic symptoms, rather than the severity of GI symptoms, was associated with less diverse gut microbiomes. Further, rigorous statistical tests with multiple testing corrections showed significantly lower abundances of the genera Prevotella, Coprococcus, and unclassified Veillonellaceae in autistic samples. These are intriguingly versatile carbohydrate-degrading and/or fermenting bacteria, suggesting a potential influence of unusual diet patterns observed in autistic children. However, multivariate analyses showed that autism-related changes in both overall diversity and individual genus abundances were correlated with the presence of autistic symptoms but not with their diet patterns. Taken together, autism and accompanying GI symptoms were characterized by distinct and less diverse gut microbial compositions with lower levels of Prevotella, Coprococcus, and unclassified Veillonellaceae.

    Children with autistic spectrum disorders are often encountered in anesthesia practice mainly for outdoor procedural sedation or anesthesia in endoscopy and magnetic resonance imaging suites. We describe a case of a 7-year-old autistic boy who required management of dental caries. He had a phobia to intravenous cannulation, displayed increasing anxiety and became combative on the day of surgery. With parental involvement and distraction, we succeeded in giving oral midazolam by concealing it, with the intent of avoiding intramuscular injection or unnecessary restraint. Lack of knowledge about the medical condition of such a patient can lead to inadequate preoperative preparation and use of restraint on the patient, which might cause anxiety or panic attacks in the operative room. To effectively manage children with special needs one needs to have clear guidelines on the management of uncooperative children, involve parents perioperatively, plan ahead with an emphasis on perioperative analgesia and sometimes incorporate the ethical use of restraint.

    The autistic spectrum disorders (ASD) form a set of multi-faceted disorders with significant genetic, epigenetic and environmental determinants. Oxidative and nitrosative stress (O&NS), immuno-inflammatory pathways, mitochondrial dysfunction and dysregulation of the tryptophan catabolite (TRYCATs) pathway play significant interactive roles in driving the early developmental etiology and course of ASD. O&NS interactions with immuno-inflammatory pathways mediate their effects centrally via the regulation of astrocyte and microglia responses, including regional variations in TRYCATs produced. Here we review the nature of these interactions and propose an early developmental model whereby different ASD genetic susceptibilities interact with environmental and epigenetic processes, resulting in glia biasing the patterning of central interarea interactions. A role for decreased local melatonin and N-acetylserotonin production by immune and glia cells may be a significant treatment target. PMID:24669209

    Objectives The aim of this literature systematic review was to evaluate the possible association between malocclusions, orthodontic treatment and development of temporomandibular disorders. Material and Methods: A search was carried out on PubMed-Medline database from January 2000 to August 2013 using the keywords “orthodontics and temporomandibular disorders”, “orthodontics and facial pain” and “malocclusion and temporomandibular disorders”. Human studies included in the study were those assessing signs and symptoms of temporomandibular disorders in relation to orthodontic treatment. Material and Methods A search was carried out on PubMed-Medline database from January 2000 to August 2013 using the keywords “orthodontics and temporomandibular disorders”, “orthodontics and facial pain” and “malocclusion and temporomandibular disorders”. Human studies included in the study were those assessing signs and symptoms of temporomandibular disorders in relation to orthodontic treatment. Results The search strategy resulted in 61 articles. After selection according to the inclusion/exclusion criteria 9 articles qualified for the final analysis. The articles which linked orthodontics and development of temporomandibular disorders showed very discrepant results. Some indicated that orthodontic treatment could improve signs and symptoms of temporomandibular disorders, but none of them obtained statistically significant differences. Conclusions According to the authors examined, there is no evidence for a cause-effect relationship between orthodontic treatment and temporomandibular disorders, or that such treatment might improve or prevent them. More longitudinal studies are needed to verify any possible interrelationship. Key words:Malocclusion and temporomandibular disorders, orthodontics and facial pain, orthodontics and temporomandibular disorders, temporomandibular disorders, temporomandibular dysfunction.

    Case histories of a mother and her two children are reported. The mother was a recovered alcoholic. She and her two children, both of whom had symptoms that are typical of autistic spectrum disorder, had dysautonomia. All had intermittently abnormal erythrocyte transketolase studies indicating abnormal thiamine pyrophosphate homeostasis. Both children had unusual concentrations of urinary arsenic. All had symptomatic improvement with diet restriction and supplementary vitamin therapy but quickly relapsed after ingestion of sugar, milk, or wheat. The stress of a heavy metal burden, superimposed on existing genetic or epigenetic risk factors, may be important in the etiology of autism spectrum disorder when in combination. Dysautonomia has been associated with several diseases, including autism, without a common etiology. It is hypothesized that oxidative stress results in loss of cellular energy and causes retardation of hard wiring of the brain in infancy, affecting limbic system control of the autonomic nervous system.

    Executive dysfunction has been shown to be a promising endophenotype in neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). This article reviewed 26 studies that examined executive function comparing ASD and/or ADHD children. In light of findings from this review, the ASD + ADHD group appears to share impairment in both flexibility and planning with the ASD group, while it shares the response inhibition deficit with the ADHD group. Conversely, deficit in attention, working memory, preparatory processes, fluency, and concept formation does not appear to be distinctive in discriminating from ASD, ADHD, or ASD + ADHD group. On the basis of neurocognitive endophenotype, the common co-occurrence of executive function deficits seems to reflect an additive comorbidity, rather than a separate condition with distinct impairments.

    This article provides a systematic review of articles on quality of life (QoL) among individuals with eating disorders. A literature search was conducted using six databases. Manual searches were also performed in two specialized journals, covering the period from January 1975 to June 2008. The search strategies identified a total of 29,537 articles. Forty-one studies met the inclusion criteria, and 36 were analyzed in the present review. Patients with eating disorders showed reduced QoL as compared to normal controls and individuals with other psychiatric disorders. The mental health component of QoL showed greater impairment than the physical component. Patients with binge eating disorders showed reduced physical and psychological QoL. We identified few studies on QoL in bulimia nervosa-only patients. QoL assessment of anorexia nervosa patients showed a modest impact on the physical domain. However, this finding should be interpreted with caution, since it may be due to an artifact in the disorder's psychopathology rather than better health status per se. PMID:20464063

    Autism, characterized by profound impairment in social interactions and communicative skills, is the most common neurodevelopmental disorder, and its underlying molecular mechanisms remain unknown. Ca2+-dependent activator protein for secretion 2 (CADPS2; also known as CAPS2) mediates the exocytosis of dense-core vesicles, and the human CADPS2 is located within the autism susceptibility locus 1 on chromosome 7q. Here we show that Cadps2-knockout mice not only have impaired brain-derived neurotrophic factor release but also show autistic-like cellular and behavioral phenotypes. Moreover, we found an aberrant alternatively spliced CADPS2 mRNA that lacks exon 3 in some autistic patients. Exon 3 was shown to encode the dynactin 1–binding domain and affect axonal CADPS2 protein distribution. Our results suggest that a disturbance in CADPS2-mediated neurotrophin release contributes to autism susceptibility. PMID:17380209

    Measurement of sleep microarchitecture and neural oscillations is an increasingly popular technique for quantifying EEG sleep activity. Many studies have examined sleep spindle oscillations in sleep-disordered adults; however reviews of this literature are scarce. As such, our overarching aim was to critically review experimental studies examining sleep spindle activity between adults with and without different sleep disorders. Articles were obtained using a systematic methodology with a priori criteria. Thirty-seven studies meeting final inclusion criteria were reviewed, with studies grouped across three categories: insomnia, hypersomnias, and sleep-related movement disorders (including parasomnias). Studies of patients with insomnia and sleep-disordered breathing were more abundant relative to other diagnoses. All studies were cross-sectional. Studies were largely inconsistent regarding spindle activity differences between clinical and nonclinical groups, with some reporting greater or less activity, while many others reported no group differences. Stark inconsistencies in sample characteristics (e.g., age range and diagnostic criteria) and methods of analysis (e.g., spindle bandwidth selection, visual detection versus digital filtering, absolute versus relative spectral power, and NREM2 versus NREM3) suggest a need for greater use of event-based detection methods and increased research standardization. Hypotheses regarding the clinical and empirical implications of these findings, and suggestions for potential future studies, are also discussed. PMID:27034850

    Caffeine is the most commonly used drug in the world. Although consumption of low to moderate doses of caffeine is generally safe, an increasing number of clinical studies are showing that some caffeine users become dependent on the drug and are unable to reduce consumption despite knowledge of recurrent health problems associated with continued use. Thus, the World Health Organization and some health care professionals recognize caffeine dependence as a clinical disorder. In this comprehensive literature review, we summarize published research on the biological evidence for caffeine dependence; we provide a systematic review of the prevalence of caffeine dependence and rates of endorsement of clinically meaningful indicators of distress and functional impairment among habitual caffeine users; we discuss the diagnostic criteria for Caffeine Use Disorder-a condition for further study included in the Diagnostic and Statistical Manual of Mental Disorders (5(th) ed.); and we outline a research agenda to help guide future clinical, epidemiological, and genetic investigations of caffeine dependence. Numerous controlled laboratory investigations reviewed in this article show that caffeine produces behavioral and physiological effects similar to other drugs of dependence. Moreover, several recent clinical studies indicate that caffeine dependence is a clinically meaningful disorder that affects a nontrivial proportion of caffeine users. Nevertheless, more research is needed to determine the reliability, validity, and prevalence of this clinically important health problem. PMID:24761279

    Neurodevelopmental disorders (NDDs) are defined as a group of disorders caused by changes in early brain development, resulting in behavioral and cognitive alterations in sensory and motor systems, speech, and language. NDDs affect approximately 1-2% of the general population. Up to 80% of children with NDDs are reported to have disrupted sleep; subsequent deleterious effects on daytime behaviors, cognition, growth, and overall development of the child are commonly reported. Examples of NDDs discussed in this review include autism spectrum disorder, cerebral palsy, Rett syndrome, Angelman syndrome, Williams syndrome, and Smith-Magenis syndrome. The etiology of sleep disorders in children with NDDs is largely heterogeneous and disease specific. The diagnosis and management of sleep disorders in this population are complex, and little high-quality data exist to guide a consistent approach to therapy. Managing sleep disorders in children with NDDs is critical both for the child and for the family but is often frustrating due to the refractory nature of the problem. Sleep hygiene must be implemented as first-line therapy; if sleep hygiene alone fails, it should be combined with pharmacologic management. The available evidence for the use of common pharmacologic interventions, such as iron supplementation and melatonin, as well as less common interventions, such as melatonin receptor agonists, clonidine, gabapentin, hypnotics, trazodone, and atypical antipsychotics is reviewed. Further, parents and caregivers should be provided with appropriate education on the nature of the sleep disorders and the expectation for modest pharmacologic benefit, at best. Additional data from well-designed trials in children with NDDs are desperately needed to gain a better understanding of sleep pharmacotherapy including efficacy and safety implications. Until then, clinicians must rely on the limited available data, as well as clinical expertise, when managing sleep disorders in the

  4. Child sexual abuse in the etiology of anxiety disorders: a systematic review of reviews.

    There is considerable controversy about the role of child sexual abuse in the etiology of anxiety disorders. Although a growing number of research studies have been published, these have produced inconsistent results and conclusions regarding the nature of the associations between child sexual abuse and the various forms of anxiety problems as well as the potential effects of third variables, such as moderators, mediators, or confounders. This article provides a systematic review of the several reviews that have investigated the literature on the role of child sexual abuse in the etiology of anxiety disorders. Seven databases were searched, supplemented with hand search of reference lists from retrieved papers. Four meta-analyses, including 3,214,482 subjects from 171 studies, were analyzed. There is evidence that child sexual abuse is a significant, although general and nonspecific, risk factor for anxiety disorders, especially posttraumatic stress disorder, regardless of gender of the victim and severity of abuse. Additional biological or psychosocial risk factors (such as alterations in brain structure or function, information processing biases, parental anxiety disorders, family dysfunction, and other forms of child abuse) may interact with child sexual abuse or act independently to cause anxiety disorders in victims in abuse survivors. However, child sexual abuse may sometimes confer additional risk of developing anxiety disorders either as a distal and indirect cause or as a proximal and direct cause. Child sexual abuse should be considered one of the several risk factors for anxiety disorders and included in multifactorial etiological models for anxiety disorders. PMID:23262751

    Sleep and sleep-related problems play a role in a large number of human disorders and affect every field of medicine. It is estimated that 50 to 70 million Americans suffer from a chronic sleep disorder, which hinders their daily life, affects their health, and confers a significant economic burden to society. The negative public health consequences of sleep disorders are enormous and could have long-term effects, including increased risk of hypertension, diabetes, obesity, heart attack, stroke and in some cases death. Polysomnographic modalities can monitor sleep cycles to identify disrupted sleep patterns, adjust the treatments, increase therapeutic options and enhance the quality of life of recording the electroencephalogram (EEG), electromyogram (EMG) and electrocardiogram (ECG). Although the skills acquired by medical facilitators are quite extensive, it is just as important for them to have access to an assortment of technologies and to further improve their monitoring and treatment capabilities. Computer-aided analysis is one advantageous technique that could provide quantitative indices for sleep disorder screening. Evolving evidence suggests that Parkinson's disease may be associated with rapid eye movement sleep behavior disorder (RBD). With this article, we are reviewing studies that are related to EMG signal analysis for detection of neuromuscular diseases that result from sleep movement disorders. As well, the article describes the recent progress in analysis of EMG signals using temporal analysis, frequency-domain analysis, time-frequency, and sparse representations, followed by the comparison of the recent research.

The purpose of this systematic literature review was to evaluate if the prevalence of sleep disorders could be ascertained from the current body of literature regarding sleep in cancer. This was a critical and systematic review of peer-reviewed, English-language, original articles published from 1980 through 15 October 2013, identified using electronic search engines, a set of key words, and prespecified inclusion and exclusion criteria. Information from 254 full-text, English-language articles was abstracted onto a paper checklist by one reviewer, with a second reviewer randomly verifying 50% (k = 99%). All abstracted data were entered into an electronic database, verified for accuracy, and analyzed using descriptive statistics and frequencies in SPSS (v.20) (North Castle, NY). Studies of sleep and cancer focus on specific types of symptoms of poor sleep, and there are no published prevalence studies that focus on underlying sleep disorders. Challenging the current paradigm of the way sleep is studied in cancer could produce better clinical screening tools for use in oncology clinics leading to better triaging of patients with sleep complaints to sleep specialists, and overall improvement in sleep quality.

    Autism spectrum disorder refers to syndromes of varying severity, typified by impaired social interactions, communicative delays and restricted, repetitive behaviours and interests. The prevalence of autism spectrum disorders has been on the rise, while the etiology remains unclear and most likely multifactorial. There have been several reports of a link between autism and chronic gastrointestinal symptoms. Endoscopy trials have demonstrated a higher prevalence of nonspecific colitis, lymphoid hyperplasia and focally enhanced gastritis compared with controls. Postulated mechanisms include aberrant immune responses to some dietary proteins, abnormal intestinal permeability and unfavourable gut microflora. Two autism spectrum disorder patients with chronic intestinal symptoms and abnormal endoscopic findings are described, followed by a review of this controversial topic. PMID:19214283

    The diet industry and media have a powerful influence over women, leading many to believe that they must modify their appearance for societal acceptance. Dietetics, as one of many predominantly female professions, may be particularly vulnerable to these pressures. An integrative review process was used to examine eating disorders and disordered eating within the dietetics profession with the aim to both synthesize existing data and develop questions for future research. Seventeen articles were reviewed using broad search terms and dates because of the dearth of available literature. Given nutrition programs and dietetic practice often involve significant exposure to food, ideas and opinions about food, weight, and its place in health and dietetic practice researchers were compelled to ask "why". Findings were organized under 3 categories including thinness ideology, implications of food and body associated with nutrition or dietetic education, and establishment of a continuum. This review serves as a platform to inspire future research in an understudied but important topic related to dietetic education and practice. Minimally as a profession, baseline data need to be collected to understand the prevalence of disordered eating and eating disorders along the continuum of practice in Canada. PMID:26067246

    At present, no treatment recommendations can be made for compulsive buying disorder. Recent studies have found evidence for the efficacy of psychotherapeutic options, but less is known regarding the best pharmacologic treatment. The purpose of this review is to present and analyze the available published evidence on the pharmacological treatment of compulsive buying disorder. To achieve this, we conducted a review of studies focusing on the pharmacological treatment of compulsive buying by searching the PubMed/MEDLINE database. Selection criteria were applied, and 21 studies were identified. Pharmacological classes reported included antidepressants, mood stabilizers, opioid antagonists, second-generation antipsychotics, and N-methyl-D-aspartate receptor antagonists. We found only placebo-controlled trials for fluvoxamine; none showed effectiveness against placebo. Three open-label trials reported clinical improvement with citalopram; one was followed by a double-blind discontinuation. Escitalopram was effective in an open-label trial but did not show efficacy in the double-blind phase. Memantine was identified as effective in a pilot open-label study. Fluoxetine, bupropion, nortriptyline, clomipramine, topiramate and naltrexone were only reported to be effective in clinical cases. According to the available literature, there is no evidence to propose a specific pharmacologic agent for compulsive buying disorder. Future research is required for a better understanding of both pathogenesis and treatment of this disorder. PMID:27067344

    Bipolar disorder (BD) is a debilitating psychiatric disorder and a growing global public health issue. Notwithstanding BD has been conceptualized as a neuroprogressive illness, there are some evidences to suggest a role for neurodevelopmental pathways in the patho-etiology of this disorder. Evidences on the associations between perinatal infections and risk for bipolar disorder have been inconsistent across studies. Here, we performed a systematic review of observational studies on the relationship between exposure to perinatal pathogens and bipolar disorder. A computerized literature search of the PubMed, Embase, and PsyINFO databases till January 31(st), 2015 was performed. Twenty-three studies ultimately met inclusion criteria. Studies investigated exposure to several pathogens namely Cytomegalovirus (CMV), Epstein-Barr Virus (EBV), Herpes simplex virus-1 (HSV-1), Herpes simplex virus-2 (HSV-2), Human herpesvirus 6 (HHV-6), Toxoplasma gondii, Influenza, and Varicella zoster virus (VZV). Overall, studies provided mixed evidences. Thus, contrary to schizophrenia, the role of perinatal infections as risk factors for BD remain inconclusive. Larger studies with a prospective design would be necessary to elucidate the role of previous exposure to infectious agents as a potential risk factor for BD. PMID:26812921

  15. [Eating disorder and the family--a review].

    The importance of the family in eating disorders has been the subject of a great deal of speculation ever since anorexia nervosa was first described some 130 years ago. Given the importance of the family in child and adolescent development, it also has great bearing on how young people learn to deal with food. But the research is inconclusive as to the family's precise role in the development of an eating disorder. There is no support in the literature on which to base a comprehensive understanding of the family setting in which a member develops an eating disorder; this also applies to anorexia nervosa cases. When groups of families afflicted with different psychiatric disorders are compared, it seems that families in which bulimia nervosa occurs tend to be more dysfunctional than families afflicted with anorexia nervosa. It also seems that families afflicted with anorexia nervosa function better than families afflicted by other psychiatric disorders. In this article the research on family functioning in relation to anorexia nervosa and bulimia nervosa is reviewed and its relevance discussed. PMID:15356692

    Autism is a socio-communication brain development disorder. It is marked by degeneration in the ability to respond to joint attention skill task, from as early as 12 to 18 months of age. This trait is used to distinguish autistic from nonautistic. In this study Near infrared spectroscopy (NIRS) is being applied for the first time to study the difference in activation and connectivity in the frontal cortex of typically developing (TD) and autistic children between 4-8 years of age in response to joint attention task. The optical measurements are acquired in real time from frontal cortex using Imagent (ISS Inc.) - a frequency domain based NIRS system in response to video clips which engenders a feeling of joint attention experience in the subjects. A block design consisting of 5 blocks of following sequence 30 sec joint attention clip (J), 30 sec non-joint attention clip (NJ) and 30 sec rest condition is used. Preliminary results from TD child shows difference in brain activation (in terms of oxy-hemoglobin, HbO) during joint attention interaction compared to the nonjoint interaction and rest. Similar activation study did not reveal significant differences in HbO across the stimuli in, unlike in an autistic child. Extensive studies are carried out to validate the initial observations from both brain activation as well as connectivity analysis. The result has significant implication for research in neural pathways associated with autism that can be mapped using NIRS.

  17. Hyperbaric oxygen therapy may improve symptoms in autistic children.

    2006-01-01

    Autism is a neurodevelopmental disorder that currently affects as many as 1 out of 166 children in the United States. Recent research has discovered that some autistic individuals have decreased cerebral perfusion, evidence of neuroinflammation, and increased markers of oxidative stress. Multiple independent single photon emission computed tomography (SPECT) and positron emission tomography (PET) research studies have revealed hypoperfusion to several areas of the autistic brain, most notably the temporal regions and areas specifically related to language comprehension and auditory processing. Several studies show that diminished blood flow to these areas correlates with many of the clinical features associated with autism including repetitive, self-stimulatory and stereotypical behaviors, and impairments in communication, sensory perception, and social interaction. Hyperbaric oxygen therapy (HBOT) has been used with clinical success in several cerebral hypoperfusion syndromes including cerebral palsy, fetal alcohol syndrome, closed head injury, and stroke. HBOT can compensate for decreased blood flow by increasing the oxygen content of plasma and body tissues and can even normalize oxygen levels in ischemic tissue. In addition, animal studies have shown that HBOT has potent anti-inflammatory effects and reduces oxidative stress. Furthermore, recent evidence demonstrates that HBOT mobilizes stem cells from human bone marrow, which may aid recovery in neurodegenerative diseases. Based upon these findings, it is hypothesized that HBOT will improve symptoms in autistic individuals. A retrospective case series is presented that supports this hypothesis. PMID:16554123

  18. Nonspeech Oral Movements and Oral Motor Disorders: A Narrative Review

    PubMed Central

    2015-01-01

    Purpose Speech and other oral functions such as swallowing have been compared and contrasted with oral behaviors variously labeled quasispeech, paraspeech, speechlike, and nonspeech, all of which overlap to some degree in neural control, muscles deployed, and movements performed. Efforts to understand the relationships among these behaviors are hindered by the lack of explicit and widely accepted definitions. This review article offers definitions and taxonomies for nonspeech oral movements and for diverse speaking tasks, both overt and covert. Method Review of the literature included searches of Medline, Google Scholar, HighWire Press, and various online sources. Search terms pertained to speech, quasispeech, paraspeech, speechlike, and nonspeech oral movements. Searches also were carried out for associated terms in oral biology, craniofacial physiology, and motor control. Results and Conclusions Nonspeech movements have a broad spectrum of clinical applications, including developmental speech and language disorders, motor speech disorders, feeding and swallowing difficulties, obstructive sleep apnea syndrome, trismus, and tardive stereotypies. The role and benefit of nonspeech oral movements are controversial in many oral motor disorders. It is argued that the clinical value of these movements can be elucidated through careful definitions and task descriptions such as those proposed in this review article. PMID:26126128

    2004-01-01

    Introduction Although the term borderline personality disorder (BPD) is used to describe adolescents in clinical settings, there is confusion as to what it comprises. To further elucidate that diagnosis, this article reviews its construct validity. Method Relevant publications appearing in PsychInfo (1872 to present) were reviewed for the purposes of this article. Results Thirty-six of the approximately sixty-five publications selected for consideration were included in this review. Conclusion The construct validity of adolescent BPD is supported by internal consistency (comparable to that of adults), group differences (ie this diagnosis segregates BPD from non-BPD adolescents), convergent validity (ie multiple measures of this disorder measure the same pathology) and concurrent validity, whereby these youth manifest functional impairment and distress. By contrast, the adolescent BPD criteria manifest less construct validity than the adult diagnosis in that its criteria did not uniformly predict the overall diagnosis, and showed more criterion overlap with other personality disorders and a broader pattern of axis II comorbidity. Further diminishing its construct validity, factor analysis suggested that adolescent BPD was not a single entity, and its low predictive validity was demonstrated by little diagnostic stability through adolescence into adulthood.

    Caffeine is the most commonly used drug in the world. Although consumption of low to moderate doses of caffeine is generally safe, an increasing number of clinical studies are showing that some caffeine users become dependent on the drug and are unable to reduce consumption despite knowledge of recurrent health problems associated with continued use. Thus, the World Health Organization and some health care professionals recognize caffeine dependence as a clinical disorder. In this comprehensive literature review, we summarize published research on the biological evidence for caffeine dependence; we provide a systematic review of the prevalence of caffeine dependence and rates of endorsement of clinically meaningful indicators of distress and functional impairment among habitual caffeine users; we discuss the diagnostic criteria for Caffeine Use Disorder—a condition for further study included in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.); and we outline a research agenda to help guide future clinical, epidemiological, and genetic investigations of caffeine dependence. Numerous controlled laboratory investigations reviewed in this article show that caffeine produces behavioral and physiological effects similar to other drugs of dependence. Moreover, several recent clinical studies indicate that caffeine dependence is a clinically meaningful disorder that affects a nontrivial proportion of caffeine users. Nevertheless, more research is needed to determine the reliability, validity, and prevalence of this clinically important health problem. PMID:24761279

    2016-06-01

    Autism spectrum disorders (ASDs) are a group of debilitating neurodevelopmental disorders thought to have genetic etiology, due to their high heritability. The endosomal system has become increasingly implicated in ASD pathophysiology. In an attempt to summarize the association between endosomal system genes and ASDs we performed a systematic review of the literature. We searched PubMed for relevant articles. Simons Foundation Autism Research Initiative (SFARI) gene database was used to exclude articles regarding genes with less than minimal evidence for association with ASDs. Our search retained 55 articles reviewed in two categories: genes that regulate and genes that are regulated by the endosomal system. Our review shows that the endosomal system is a novel pathway implicated in ASDs as well as other neuropsychiatric disorders. It plays a central role in aspects of cellular physiology on which neurons and glial cells are particularly reliant, due to their unique metabolic and functional demands. The system shows potential for biomarkers and pharmacological intervention and thus more research into this pathway is warranted. PMID:27048963

    Based on a literature review, the purpose is to identify the main therapeutic approaches for the compulsive buying disorder, a present time disorder characterized by excessive and uncontrollable concerns or behaviors related to buying or expenses, which may lead to adverse consequences. The systematic review was carried out by searching the electronic scientific bases Medline/Pubmed, ISI, PsycInfo. The search was comprised of full-text articles, written in Portuguese and English, with no time limit or restrictions on the type of study and sample. A total of 1659 references were found and, by the end, 23 articles were selected for this review. From the articles found, it was determined that, although there are case studies and clinical trials underlining the effectiveness of the treatment for compulsive buying, only those studies with a focus on the cognitive-behavioral therapy approach make evident the successful response to the treatment. The publication of new studies on the etiology and epidemiology of the disorder is necessary, in order to establish new forms of treatment and to verify the effectiveness and response of the Brazilian population to the existing protocols.

    2016-06-01

    In the philosophy of well-being, there is hardly anything written on the lives of people with autism or on the question whether existing philosophical theories of well-being are suited for understanding how well the lives of autistic persons are going. This paper tries to make some progress towards filling this gap. I start by giving a concise account of autism, which highlights the huge heterogeneity among autistics. I discuss some basic features of autism, ask whether there are good reasons why we would need an account of well-being specifically for autistics and what philosophical well-being research could learn from being informed by autistic experiences and phenomenology. I then investigate to what extent the capability approach gives us a helpful theory of well-being for autistics, and what looking through an autism-lens can contribute to the further development of the capabilitarian well-being. In particular, I show that some capabilities that are crucially relevant for autistics are also relevant for the lives of non-autistic people. The final part of the paper looks at an important difficulty in using the capabilitarian account of well-being for autistics, namely: should the normative focus be on achievements (functionings) or real opportunities (capabilities)?

    The present study was conducted to investigate the effectiveness of a program designed to teach behavior modification procedures to normal siblings of autistic children. Three sibling pairs participated in a multiple-baseline analysis of the effects of training the normal siblings to use behavior modification procedures to teach their autistic brother or sister a variety of learning tasks. Results indicated that the siblings learned to use the behavioral procedures at a high level of proficiency, they used the procedures in a generalization setting, and there were observed improvements in the behavior of the autistic children. In addition, a social validation assessment of the normal siblings' statements about their autistic sibling indicated a decrease in negative statements and an increase in positive statements after training. These results are discussed in terms of the potential for incorporating siblings into the treatment plan in intervention programs with autistic children. PMID:6885667

    2016-01-01

    Background Disasters are traumatic events that may result in a wide range of mental and physical health consequences. Post-traumatic stress disorder (PTSD) is probably the most commonly studied post-disaster psychiatric disorder. This review aimed to systematically assess the evidence about PTSD following exposure to disasters. Method A systematic search was performed. Eligible studies for this review included reports based on the DSM criteria of PTSD symptoms. The time-frame for inclusion of reports in this review is from 1980 (when PTSD was first introduced in DSM-III) and February 2007 when the literature search for this examination was terminated. Results We identified 284 reports of PTSD following disasters published in peer-reviewed journals since 1980. We categorized them according to the following classification: (1) human-made disasters (n=90), (2) technological disasters (n=65), and (3) natural disasters (n=116). Since some studies reported on findings from mixed samples (e.g. survivors of flooding and chemical contamination) we grouped these studies together (n=13). Conclusions The body of research conducted after disasters in the past three decades suggests that the burden of PTSD among persons exposed to disasters is substantial. Post-disaster PTSD is associated with a range of correlates including sociodemographic and background factors, event exposure characteristics, social support factors and personality traits. Relatively few studies have employed longitudinal assessments enabling documentation of the course of PTSD. Methodological limitations and future directions for research in this field are discussed.

    2015-01-01

    Challenges to epidemiological studies of eating and related body image disturbance disorders in males include, in addition to low base rates and the predominance of residual diagnostic categories, the female-centric nature of current classification schemes and the consequent lack of appropriate assessment instruments. In this narrative review, we summarise epidemiological data regarding the prevalence and correlates of eating disorders, related body image disturbance disorders, and eating disorder features in males. Attention is focused on disorders most likely to be observed among males, such as muscle dysmorphia and muscularity-oriented excessive exercise. It is argued that, given the multiple challenges involved in research of this kind, a focus on features is more likely to advance the field than a focus on diagnoses. In terms of correlates, we focus on impairment and help-seeking, since these issues are most relevant in informing public health burden, service provision, and related issues. We end with some thoughts about current gaps in the knowledge base and directions for future research that we consider to be most promising. PMID:27408719

    2010-01-01

    Objective Based on the increased recognition of the dimensional nature of autistic traits, we examined their neural correlates in neurotypical individuals using the Social Responsiveness Scale-Adult version (SRS-A). The SRS-A measures autistic traits that are continuously distributed in the general population. Here, we establish a novel approach to examining the neural basis of autistic traits, attempting to directly relate SRS-A scores to patterns of functional connectivity observed for the pregenual anterior cingulate cortex (pgACC), a region commonly implicated in social cognition. Methods Resting state fMRI scans were collected in 25 neurotypical individuals (26.4 ± 5.6 y) who provided SRS-A completed by an informant who knew the participant in natural social settings. Whole brain corrected connectivity analyses were then conducted using the SRS-A as a covariate of interest. Results We found a significant negative relationship between SRS-A and pgACC functional connectivity with the anterior portion of mid-insula (Z > 2.3; p < .05, corrected). Specifically, low levels of autistic traits were observed when a substantial portion of the anterior mid-insula showed positive connectivity with pgACC. In contrast, elevated levels of autistic traits were associated with negative connectivity between the pgACC and the anterior mid-insula. Conclusions Resting state functional connectivity of the pgACC-insula social network was related to autistic traits in neurotypical adults. Application of this approach in samples with autism spectrum disorders is needed to confirm whether the pgACC- anterior mid insula circuit is dimensionally related to the severity of autistic traits in clinical populations.

    2014-01-01

    Background Theoretical and anecdotal support for the role of shame in obsessive compulsive related disorders (OCRDs) is prominent. Developing our understanding of shame’s role in OCRDs is important to building knowledge about this new diagnostic category. This review aims to consolidate our understanding of shame in each OCRD, through summarizing existing clinical, conceptual, and empirical work. Methods We provide an overview of shame, its measurement considerations, and a full review of 110 articles addressing shame in OCRDs. Results General shame and shame about having a mental illness are the broadest types of shame relevant to OCRDs; symptom-based shame and body shame may be more specific to OCRDs. In OCD, violent, sexual, or blasphemous obsessions may trigger symptom-based shame. In trichotillomania (TTM) and skin picking (SP), symptom-based shame may be related to pulling, picking, and post-pulling/picking behaviors. In hoarding disorder, symptom-based shame may accompany beliefs about being defective due to living with clutter. Body shame appears inherent to body dysmorphic disorder, while in TTM and SP it may arise as a secondary response to damage resulting from body focused repetitive behaviors. Limitations Much of the current knowledge on shame in OCRDs comes from anecdotal, case, and conceptual work. Empirical studies do not always assess specific types of shame, instead assessing shame as a general construct. Conclusions Shame is closely related to OCRDs. Clinical and research recommendations drawing from the literature are provided. PMID:25299438

    2012-12-01

    Apotemnophilia or body integrity identity disorder (BIID) denotes a syndrome in which a person is preoccupied with the desire to amputate a healthy limb. In this report, we review the available case reports in the literature in order to enhance psychiatrists' and physicians' comprehension of this disorder. A search for the case reports available via MEDLINE was done since the first case report published by Money et al in 1977 till May 2011, using the following terms: apotemnophilia, self-demand amputation, body integrity identity disorder, and BIID. In all, 14 case reports were found relevant to our search. The desire to amputate one's healthy limb seems to be related to a major disturbance in the person's perception of one's own identity, where limb amputation can relieve temporarily the patient's feeling of distress without necessarily and uniformly adjusting the patient's own identity misperception. More investigations are needed in this domain in order to develop noninvasive treatment strategies that approach this aspect of the patient's distress within a globalist perspective. In addition, the health professionals' awareness regarding this disorder is required to ensure professional management of patients' suffering. PMID:23089967

    2016-01-01

    The current literature shows growing evidence of a link between gender dysphoria (GD) and autism spectrum disorder (ASD). This study reviews the available clinical and empirical data. A systematic search of the literature was conducted using the following databases: PubMed, Web of Science, PsycINFO and Scopus; utilizing different combinations of the following search terms: autism, autism spectrum disorder (ASD), Asperger's disorder (AD), co-morbidity, gender dysphoria (GD), gender identity disorder (GID), transgenderism and transsexualism. In total, 25 articles and reports were selected and discussed. Information was grouped by found co-occurrence rates, underlying hypotheses and implications for diagnosis and treatment. GD and ASD were found to co-occur frequently - sometimes characterized by atypical presentation of GD, which makes a correct diagnosis and determination of treatment options for GD difficult. Despite these challenges there are several case reports describing gender affirming treatment of co-occurring GD in adolescents and adults with ASD. Various underlying hypotheses for the link between GD and ASD were suggested, but almost all of them lack evidence. PMID:26753812

    Acton, P D; Mozley, P D

    2000-01-01

    Parkinsonian symptoms are associated with a number of neurodegenerative disorders, such as Parkinson's disease, multiple system atrophy and progressive supranuclear palsy. Pathological evidence has shown clearly that these disorders are associated with a loss of neurons, particularly in the nigrostriatal dopaminergic pathway. Positron emission tomography (PET) and single photon emission tomography (SPECT) now are able to visualise and quantify changes in cerebral blood flow, glucose metabolism, and dopaminergic function produced by parkinsonian disorders. Both PET and SPECT have become important tools in the differential diagnosis of these diseases, and may have sufficient sensitivity to detect neuronal changes before the onset of clinical symptoms. Imaging is now being utilised to elucidate the genetic contribution to Parkinson's disease, and in longitudinal studies to assess the efficacy and mode of action of neuroprotective drug and surgical treatments. This review summarises recent applications of SPECT imaging in the study of parkinsonian disorders, with particular reference to the increasing role it is playing in the understanding, diagnosis and management of these diseases.

    PubMed

    Adalbert, R; Coleman, M P

    2013-02-01

    'Dying back' axon degeneration is a prominent feature of many age-related neurodegenerative disorders and is widespread in normal ageing. Although the mechanisms of disease- and age-related losses may differ, both contribute to symptoms. Here, we review recent advances in understanding axon pathology in age-related neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and glaucoma. In particular, we highlight the importance of axonal transport, autophagy, traumatic brain injury and mitochondrial quality control. We then place these disease mechanisms in the context of changes to axons and dendrites that occur during normal ageing. We discuss what makes ageing such an important risk factor for many neurodegenerative disorders and conclude that the processes of normal ageing and disease combine at the molecular, cellular or systems levels in a range of disorders to produce symptoms. Pathology identical to disease also occurs at the cellular level in most elderly individuals. Thus, normal ageing and age-related disease are inextricably linked and the term 'healthy ageing' downplays the important contributions of cellular pathology. For a full understanding of normal ageing or age-related disease we must study both processes. PMID:23046254

    1980-01-01

    The Achilles tendon and the classification, etiology, diagnosis, treatment, and management of Achilles tendon disorders in runners are reviewed. Due to the presence of a paratenon sheath, the classification of Achilles tendon disease should be revised. Several etiological mechanisms have been proposed in Achilles tendon disease. The authors recognize: faulty foot biomechanics; poor lower leg flexibility; poorly designed athletic footwear; training surfaces; training intensity; overuse through excessive mileage; inactivity; local steroid injections; rheumatic conditions; and indirect violence. An accurate, thorough differential diagnosis is essential when the athlete presents with an Achilles tendon disorder. Except in total rupture and in extensive partial rupture, the authors do not recommend cast immobilization in the treatment of Achilles tendon disease. When the athlete presents with total rupture of the Achilles tendon, the authors believe that surgical repair is the treatment method of choice. Rehabilitation programs to follow successful treatment of Achilles tendon disease are also presented. PMID:6999281

    2014-03-01

    Olfactory disorders are common and affect about one-fifth of the general population. The main causes of olfactory loss are post viral upper respiratory infection, nasal/sinus disease, and head trauma and are therefore very frequent among patients in ear, nose, and throat clinics. We have systematically reviewed the impact of quantitative, qualitative, and congenital olfactory disorders on daily life domains as well as on general quality of life and depression. From the extensive body of literature, it can be concluded that loss of the sense of smell leads to disturbances in important areas, mainly in food enjoyment, detecting harmful food and smoke, and to some extent in social situations and working life. Most patients seem to deal well and manage those restrictions. However, a smaller proportion has considerable problems and expresses a noticeable reduction in general quality of life and enhanced depression. The impact of coping strategies is discussed.

    While considered for years to play the primary role in the etiology of temporo-mandibular joint disturbances (TMD), occlusal discrepancies are now considered to be just one causative factor among many. Recent studies, literature reviews or meta-analyses, and longitudinal studies with follow-up of children treated for many years all conclude that there is no risk of orthodontic treatment giving rise to episodes of temporo-mandibular disorders. The signs of TMD appearing during the course of orthodontic treatment should be considered in the context of the epidemiology of the disorder, which is characterized by a strong increase in its occurrence during adolescence. In conclusion, it should be stated that if orthodontic treatment can no longer be considered as one of the etiopathogenic factors in the TMD complex, there are no scientific arguments to justify the converse, that there are indications for orthodontic treatment whose sole goal would be the treatment of TMD.

    Patients suffering from body dysmorphic disorder (BDD) are preoccupied with an imagined or minor defect in appearance that causes significant distress and impairment in social and occupational functioning. Despite a rate of up to 15% of BDD patients reported in cosmetic surgery settings, there is no consensus on the best management for these patients. The main purpose of this article was to conduct a literature review on BDD and cosmetic surgery. Properly trained healthcare professionals in recognizing and diagnosing this pathology is essential for the delivery of quality psychiatric care while taking into account the high prevalence of body dysmorphic disorder patients in cosmetic surgery and the poor outcome of these patients following cosmetic procedures.

    Obsessive–compulsive disorder (OCD) is a highly researched and conceptualized disorder, and yet it remains one of the most debilitating, widespread, and expensive disorders one can be afflicted with [Real, E., Labad, J., Alonso, P., Segalas, C., Jimenez-Murcia, S., Bueno, B., … Menchon, J. M. (2011). Stressful life events at onset of obsessive–compulsive disorder are associated with a distinct clinical pattern. Depression and Anxiety, 28, 367–376. doi:10.1002/da.20792]. Exposure treatments and cognitive-behavioural therapy (CBT) have been largely accepted as best practice for those with OCD, and yet there are still many who are left with “treatment-resistant OCD” [Rowa, K., Antony, M., & Swinson, R. (2007). Exposure and response prevention. In C. Purdon, M. Antony, & L. J. Summerfeldt (Eds.), Psychological treatment of obsessive-compulsive disorder: Fundamentals and beyond (pp. 79–109). Washington, DC: American Psychological Association; Foa, E. B. (2010). Cognitive behavioural therapy of obsessive–compulsive disorder. Dialogues of Clinical Neuroscience, 12, 199–207]. Similarly, exposure treatments and CBT have been accepted as best practice for trauma-related distress (i.e. post-traumatic stress disorder; Foa, E. B., Keane, T. M., Friedman, M. J., & Cohen, J. A. (2009). Effective treatments for PTSD: Practice guidelines from the international society for traumatic studies (2nd ed.). New York, NY: The Guilford Press). From a literature review, evidence has been provided that demonstrates a high prevalence rate (30–82%) of OCD among individuals with a traumatic history in comparison to the prevalence rate of the general population (1.1–1.8%; [Cromer, K.

  7. The Autism-Spectrum Quotient and Visual Search: Shallow and Deep Autistic Endophenotypes.

    A high Autism-Spectrum Quotient (AQ) score (Baron-Cohen et al. in J Autism Dev Disord 31(1):5-17, 2001) is increasingly used as a proxy in empirical studies of perceptual mechanisms in autism. Several investigations have assessed perception in non-autistic people measured for AQ, claiming the same relationship exists between performance on perceptual tasks in high-AQ individuals as observed in autism. We question whether the similarity in performance by high-AQ individuals and autistics reflects the same underlying perceptual cause in the context of two visual search tasks administered to a large sample of typical individuals assessed for AQ. Our results indicate otherwise and that deploying the AQ as a proxy for autism introduces unsubstantiated assumptions about high-AQ individuals, the endophenotypes they express, and their relationship to Autistic Spectrum Conditions (ASC) individuals.

    Individuals with autism spectrum disorders are claimed to show a local cognitive bias, termed “weak central coherence”, which manifests in a reduced influence of contextual information on linguistic processing. Here, we investigated whether this bias might also be demonstrated by individuals who exhibit sub-clinical levels of autistic traits, as has been found for other aspects of autistic cognition. The eye-movements of 71 university students were monitored as they completed a reading comprehension task. Consistent with previous studies, participants made shorter fixations on words that were highly predicted on the basis of preceding sentence context. However, contrary to the weak central coherence account, this effect was not reduced amongst individuals with high levels of autistic traits, as measured by the Autism Spectrum Quotient (AQ). Further exploratory analyses revealed that participants with high AQ scores fixated longer on words that resolved the meaning of an earlier homograph. However, this was only the case for sentences where the two potential meanings of the homograph result in different pronunciations. The results provide tentative evidence for differences in reading style that are associated with autistic traits, but fail to support the notion of weak central coherence extending into the non-autistic population.

    The study of proteomics could explain many aspects of obstetric disorders. We undertook this review with the aim of assessing the utility of proteomics in the specialty of obstetrics. We searched the electronic databases of MEDLINE, EBSCOhost, BVS Bireme, and SciELO, using various search terms with the assistance of a librarian. We considered cohort studies, case-control studies, case series, and systematic review articles published until October 2014 in the English or Spanish language, and evaluated their quality and the internal validity of the evidence provided. Two reviewers extracted the data independently, then both researchers simultaneously revised the data later, to arrive at a consensus. The search retrieved 1,158 papers, of which 965 were excluded for being duplicates, not relevant, or unrelated studies. A further 86 papers were excluded for being guidelines, protocols, or case reports, along with another 64 that did not contain relevant information, leaving 43 studies for inclusion. Many of these studies showed the utility of proteomic techniques for prediction, pathophysiology, diagnosis, management, monitoring, and prognosis of pre-eclampsia, perinatal infection, premature rupture of membranes, preterm birth, intrauterine growth restriction, and ectopic pregnancy. Proteomic techniques have enormous clinical significance and constitute an invaluable weapon in the management of obstetric disorders that increase maternal and perinatal morbidity and mortality.

    Mood disorders are a major public health problem and are associated with considerable burden of disease, suicides, physical comorbidities, high economic costs, and poor quality of life. Approximately 30%–40% of patients with major depression have only a partial response to available pharmacological and psychotherapeutic interventions. Complementary and alternative medicine (CAM) has been used either alone or in combination with conventional therapies in patients with mood disorders. This review of the literature examines evidence-based data on the use of CAM in mood disorders. A search of the PubMed, Medline, Google Scholar, and Quertile databases using keywords was conducted, and relevant articles published in the English language in the peer-reviewed journals over the past two decades were retrieved. Evidence-based data suggest that light therapy, St John’s wort, Rhodiola rosea, omega-3 fatty acids, yoga, acupuncture, mindfulness therapies, exercise, sleep deprivation, and S-adenosylmethionine are effective in the treatment of mood disorders. Clinical trials of vitamin B complex, vitamin D, and methylfolate found that, while these were useful in physical illness, results were equivocal in patients with mood disorders. Studies support the adjunctive role of omega-3 fatty acids, eicosapentaenoic acid, and docosahexaenoic acid in unipolar and bipolar depression, although manic symptoms are not affected and higher doses are required in patients with resistant bipolar depression and rapid cycling. Omega-3 fatty acids are useful in pregnant women with major depression, and have no adverse effects on the fetus. Choline, inositol, 5-hydroxy-L-tryptophan, and N-acetylcysteine are effective adjuncts in bipolar patients. Dehydroepiandrosterone is effective both in bipolar depression and depression in the setting of comorbid physical disease, although doses should be titrated to avoid adverse effects.

    Anxiety disorders are the most common psychiatric disorders observed currently. It is a normal adaptive response to stress that allows coping with adverse situations. Nevertheless, when anxiety becomes excessive or disproportional in relation to the situation that evokes it or when there is not any special object directed at it, such as an irrational dread of routine stimuli, it becomes a disabling disorder and is considered to be pathological. The traditional treatment used is medication and cognitive behavioral psychotherapy, however, last years the practice of physical exercise, specifically aerobic exercise, has been investigated as a new non-pharmacological therapy for anxiety disorders. Thus, the aim of this article was to provide information on research results and key chains related to the therapeutic effects of aerobic exercise compared with other types of interventions to treat anxiety, which may become a useful clinical application in a near future. Researches have shown the effectiveness of alternative treatments, such as physical exercise, minimizing high financial costs and minimizing side effects. The sample analyzed, 66.8% was composed of women and 80% with severity of symptoms anxiety as moderate to severe. The data analyzed in this review allows us to claim that alternative therapies like exercise are effective in controlling and reducing symptoms, as 91% of anxiety disorders surveys have shown effective results in treating. However, there is still disagreement regarding the effect of exercise compared to the use of antidepressant symptoms and cognitive function in anxiety, this suggests that there is no consensus on the correct intensity of aerobic exercise as to achieve the best dose-response, with intensities high to moderate or moderate to mild.

    The therapeutic impact of exercise interventions in psychiatric diseases such as depression, anxiety and schizophrenia has already been proven through several reviews whereas substance use disorders such as alcohol use disorders (AUD) have so far less frequently been a matter of investigation. Although several publications have summarized studies focusing on physical activities in substance use disorders, no systematic review exists summarizing the evidence of exercise interventions in AUD. A total of 14 studies using the Medline Database, CCMed, Cochrane Library and PsychINFO were identified and met the inclusion criteria. In order to evaluate the evidence, we used the evaluation system of the Oxford Centre for Evidence-Based Medicine (2011). Due to methodological flaws the overall evidence of the studies is rated level "3" but primarily findings confirm that exercise interventions as a complementary treatment component in AUD are feasible and safe. No adverse events were reported. This systematic review indicates that exercise may have beneficial effects on certain domains of physical functioning including VO2max, basal heart rate, physical activity level and strength. Inconsistent effects with a slight trend towards a positive effect on anxiety, mood management, craving, and drinking behavior have been shown and need to be verified. Results must be interpreted cautiously due to the numerous methodological flaws and the heterogeneity of the interventions and measures. However, according to preclinical studies several mechanisms of action are conceivable, especially as to alcohol-related outcomes and additionally seem to be promising. RCTs with high methodological quality are urgently needed in future research to establish evidence-based exercise recommendations for the treatment of AUD. PMID:25641736

    Posttraumatic stress disorder (PTSD) and sleep-disordered breathing (SDB) are common disorders, but limited data address their co-morbidity. Emerging research indicates PTSD and SDB may co-occur more frequently than expected and may impact clinical outcomes. This review describes historical developments that first raised suspicions for a co-morbid relationship between PTSD and SDB, including barriers to the recognition and diagnosis of this co-morbidity. Objective diagnostic data from polysomnography studies in PTSD patients reveal widely varying prevalence rates for co-morbidity (0-90%). Use of standard, recommended technology (nasal cannula pressure transducer) versus older, less reliable technology (thermistor/thermocouple) appears to have influenced objective data acquisition and therefore SDB rates in sleep studies on PTSD patients. Studies using higher quality respiratory sensors demonstrated the highest prevalence of SDB in PTSD patients. Clinical relevance, theoretical models and research recommendations are discussed. The lack of widely acknowledged, tested, or proven explanatory models and pathophysiological mechanisms to understand the relationship between these two disorders may prove formidable barriers to further investigations on prevalence and clinical relevance, albeit both conditions are associated with waking or sleeping hyperarousal activity, which may inform future studies.

    Relapse is common in substance use disorders (SUDs), even among treated individuals. The goal of this article was to systematically review the existing evidence on mindfulness meditation-based interventions (MM) for SUDs. The comprehensive search for and review of literature found over 2,000 abstracts and resulted in 25 eligible manuscripts (22 published, 3 unpublished: 8 RCTs, 7 controlled non-randomized, 6 non-controlled prospective, 2 qualitative studies, 1 case report). When appropriate, methodological quality, absolute risk reduction, number needed to treat, and effect size (ES) were assessed. Overall, although preliminary evidence suggests MM efficacy and safety, conclusive data for MM as a treatment of SUDs are lacking. Significant methodological limitations exist in most studies. Further, it is unclear which persons with SUDs might benefit most from MM. Future trials must be of sufficient sample size to answer a specific clinical question and should target both assessment of effect size and mechanisms of action. PMID:19904664

    Somatic treatments other than psychotropic drugs are increasingly used in the patients with obsessive compulsive disorder (OCD), however there has been little systematic review of them. Therefore, the present review deals with a variety of somatic treatment methods excluding psychotropic drugs. A literature search was performed on the PubMed database from the beginning of 1980, to September 2012, for published English, Turkish and French-language articles of somatic treatment approaches (excluding psychopharmacological agents) in the treatment of OCD. The search was carried out by using some terms in detail. Afterwards, the obtained investigations on electroconvusive therapy (ECT), deep brain stimulation (DBS), neurosurgical methods and transcranial magnetic stimulation (TMS) were presented. Although psychopharmacological treatment and psychotherapeutic approaches are primary treatment modalities in the management of OCD, other somatic treatment options seem to be used as alternatives, especially for patients with treatmentresistant OCD.

    OBJECTIVE--To review a series of conceptual and methodological problems encountered in surveys primarily devoted to pain disorders. CRITERIA FOR INCLUSION AND EXCLUSION OF ARTICLES--Published reports were systematically collected by electronic database searches (Medline), citations in existing publications, and through personal contacts. Relevant articles from clinical and epidemiological research on pain were included and special attention was given to epidemiological research on back pain. CONCLUSIONS--Surveys of pain disorders should be based on a multidimensional pain model that includes nociceptive input, pain perception, suffering, and pain behaviour as major components. Because of the limited applicability of diagnostic procedures or genuine "non-specificity" of pain states, or both, epidemiological surveys may result in a considerable proportion of cases without an identifiable pathophysiological basis. Staging and grading procedures for pain disorders (as distinguished from classification) may comprise various aspects of pain perception: regional distribution, pain intensity, temporal characteristics, sensory qualities, and dimensions of cognitive-emotional appraisal. Description of temporal development and chronification (staging) should refer to different components of the multidimensional pain model. Explicit a posteriori procedures for grading are preferable to implicit grading based on question wording. Evidence from several sources suggests that localistic concepts of pain may be misleading. Identification of complex pain syndromes should be one primary target for epidemiological pain surveys. Of the many factors that may impair the reliability and validity of data collected in pain surveys, recall biases seem to deserve special attention. PMID:7830005

    This article reviews the state-of-the-art research in posttraumatic stress disorder (PTSD) from several perspectives: (1) Sex differences: PTSD is more frequent among women, who tend to have different types of precipitating traumas and higher rates of comorbid panic disorder and agoraphobia than do men. (2) Risk and resilience: The presence of Group C symptoms after exposure to a disaster or act of terrorism may predict the development of PTSD as well as comorbid diagnoses. (3) Impact of trauma in early life: Persistent increases in CRF concentration are associated with early life trauma and PTSD, and may be reversed with paroxetine treatment. (4) Imaging studies: Intriguing findings in treated and untreated depressed patients may serve as a paradigm of failed brain adaptation to chronic emotional stress and anxiety disorders. (5) Neural circuits and memory: Hippocampal volume appears to be selectively decreased and hippocampal function impaired among PTSD patients. (6) Cognitive behavioral approaches: Prolonged exposure therapy, a readily disseminated treatment modality, is effective in modifying the negative cognitions that are frequent among PTSD patients. In the future, it would be useful to assess the validity of the PTSD construct, elucidate genetic and experiential contributing factors (and their complex interrelationships), clarify the mechanisms of action for different treatments used in PTSD, discover ways to predict which treatments (or treatment combinations) will be successful for a given individual, develop an operational definition of remission in PTSD, and explore ways to disseminate effective evidence-based treatments for this condition.

    Impairment in reciprocal social interaction in children that is less severe than autism can be difficult to diagnose due to the variety of developmental pathways that may lead to this problem. Seven childhood disorders are reviewed that include impaired reciprocal interaction: multisystem developmental disorder, nonverbal learning disability syndrome, semantic-pragmatic disorder, attachment disorders (including a developmental theory of limbic system damage), multiplex developmental disorder, schizoid personality disorder, and pervasive developmental disorder not otherwise specified. Clarification is needed for most of the disorders in the areas of operationalized criteria, assessment tools, and documenting causal relationships. PMID:11579660
