The anxiety, obsessive-compulsive, and trauma- and stressor-related disorders are, together, the most common class of mental disorders. From a systematic review of prevalence studies across 44 countries, the global current prevalence for the DSM IV anxiety disorders was estimated at 7.3% (95% CI 4.8%–10.9%), suggesting that one in 14 people around the world at any given time has an anxiety disorder. Women are approximately twice as likely as men to have an anxiety disorder. Anxiety disorders are a substantial contributor to the heavy burden of disease conveyed by mental and substance use disorders worldwide, where they are second only to depressive disorders in years-lost-to-disabilility.

Abstract Objective The aim of this systematic review and meta-analysis was to provide an estimate of the prevalence of anxiety and depressive disorders in youth with epilepsy (YWE). It also aimed to calculate the overall magnitude of observed differences in anxiety and depressive symptoms reported by YWE compared with healthy controls and investigate whether any factors moderated anxiety and depression outcomes in YWE. Methods Following prospective registration, electronic databases were searched up until October 2018. Studies were included if they reported on the rate of anxiety or depression in samples of YWE, and/or if they used valid measures of anxious or depressive symptomatology in YWE compared with a healthy control sample. Results Twenty-three studies met inclusion criteria. The overall pooled prevalence of anxiety disorders in YWE was 18.9% (95% confidence interval [CI] 12.0%–28.5%), and for depression the pooled prevalence was 13.5% (95% CI 8.8%–20.2%). In samples of YWE compared with healthy controls, significantly higher anxiety (d = 0.57, 95% CI 0.32–0.83, p < .000) and depressive (d = 0.42, 95% CI 0.16–0.68, p < .000) symptomatology was reported. Conclusions YWE report anxiety and depressive disorders and symptoms to a significantly higher degree than youth without epilepsy. There is also evidence that certain anxiety disorders (e.g. generalized anxiety disorder, separation anxiety disorder) are particularly elevated, perhaps reflecting the unique impact of epilepsy on youth psychopathology. Research is needed to understand the risk factors associated with anxiety and depressive disorders in epilepsy, and better understand how these symptoms change across development.

Background Although there have been many changes in the diagnosis of anxiety and depressive disorders in the past 20 years there have been few comparative enquiries into the clinical outcome of greater diagnostic categories. We therefore compared the outcome of all studies which compared the outcome of specific anxiety and depressive disorders using the standard procedures of systematic review.Method A Medline search was carried out of all studies comparing the outcome of anxiety and depressive disorders or mixed anxiety-depressive disorders in which information was available separately for each disorder.Results Eight studies satisfied the search criteria (all involving a period of observation of two years or greater); only one of these included randomisation of treatment and comparison between specific anxiety disorder outcome. There was a somewhat better outcome in patients with depressive disorders compared with anxiety ones, and strong evidence that both anxiety and depressive disorders singly had better outcomes than comorbid mixed disorders.Conclusion Comorbid anxiety-depressive disorders have a poor outcome compared with single anxiety and depressive disorders, and there is some evidence that anxiety disorders have a worse outcome than depressive ones.

Evidence in the literature indicates that neurocognitive impairments may represent endophenotypes in psychiatric disorders. Objective: This study aimed to conduct a systematic review on executive functions as a potential neurocognitive endophenotype in anxiety disorder diagnosis according to the DSM-IV and DSM-5 classifications. Methods: A literature search of the LILACS, Cochrane Library, Index Psi Periódicos Técnico-Científicos, PubMed and PsycInfo databases was conducted, with no time limits. Of the 259 studies found, 14 were included in this review. Results: Only studies on obsessive-compulsive disorder (OCD) were found. The executive function components of decision-making, planning, response inhibition, behavioral reversal/alternation, reversal learning and set-shifting/cognitive flexibility were considered to be a neurocognitive endophenotypes in OCD. Conclusion: Further studies on executive functions as a neurocognitive endophenotype in other anxiety disorders are needed since these may have different neurocognitive endophenotypes and require other prevention and treatment approaches.

Background This study explores the temporal relationship between anxiety and major depressive disorders in a cohort of patients with current major depression.Method Current prevalence and lifetime history of specific anxiety disorders were assessed using the Structured Clinical Interview for DSM–III–R Diagnosis (SCID–P) in 85 patients with DSM–III–R major depression. Consensus DSM–III–R diagnoses were assigned by at least two psychiatrists or psychologists.Results Twenty-nine per cent met criteria for at least one current anxiety disorder and 34% had at least one anxiety disorder at some point in their lives. The mean (s.d.) age of onset of anxiety disorder in the depressed patients with comorbid social or simple phobia (15 (9) years) was significantly younger than was that of their major depression (25 (9) years). In contrast, the mean (s.d.) age of onset of anxiety in patients with comorbid panic or OCD (20 (8) years) was similar to that seen for their major depression (21 (9) years). In patients with major depression with comorbid anxiety disorders, both the social phobia (10 of 13) and simple phobia (4 of 4) were more commonly reported to start at least two years prior to their major depression in contrast to depressives with comorbid panic (3 of 10 subjects) – Fisher's exact test, P=0.01.Conclusions Early-onset social and simple phobias appear to be risk factors for later onset of major depression.

BackgroundThe literature describing the global prevalence of anxiety disorders is highly variable. A systematic review and meta-regression were undertaken to estimate the prevalence of anxiety disorders and to identify factors that may influence these estimates. The findings will inform the new Global Burden of Disease study.MethodA systematic review identified prevalence studies of anxiety disorders published between 1980 and 2009. Electronic databases, reference lists, review articles and monographs were searched and experts then contacted to identify missing studies. Substantive and methodological factors associated with inter-study variability were identified through meta-regression analyses and the global prevalence of anxiety disorders was calculated adjusting for study methodology.ResultsThe prevalence of anxiety disorders was obtained from 87 studies across 44 countries. Estimates of current prevalence ranged between 0.9% and 28.3% and past-year prevalence between 2.4% and 29.8%. Substantive factors including gender, age, culture, conflict and economic status, and urbanicity accounted for the greatest proportion of variability. Methodological factors in the final multivariate model (prevalence period, number of disorders and diagnostic instrument) explained an additional 13% of variance between studies. The global current prevalence of anxiety disorders adjusted for methodological differences was 7.3% (4.8–10.9%) and ranged from 5.3% (3.5–8.1%) in African cultures to 10.4% (7.0–15.5%) in Euro/Anglo cultures.ConclusionsAnxiety disorders are common and the substantive and methodological factors identified here explain much of the variability in prevalence estimates. Specific attention should be paid to cultural differences in responses to survey instruments for anxiety disorders.

Women are more likely than men to meet lifetime criteria for an anxiety disorder. Moreover, anxiety is a risk factor for the development of other psychiatric conditions, including major depression. Numerous studies have identified evidence of sex differences in anxiety disorders, and there is considerable research concerning factors that may contribute to vulnerability for anxiety in females. In addition to psychosocial influences, biological components such as the female reproductive hormone cycle have also been implicated. Although psychotropic medication is more likely to be prescribed to women, there is little controlled data available concerning sex differences in the efficacy and/or tolerability of pharmacotherapy in anxiety disorders. This chapter provides an overview of the impact of gender in the epidemiology, phenomenology, course, and treatment response in generalized anxiety disorder (GAD), social anxiety disorder (SAD), posttraumatic stress disorder (PTSD), panic disorder (PD), and obsessive-compulsive disorder (OCD).

Objective: The aim of this study to determine the prevalence of anxiety disorders in publically treated psychiatric inpatients with a DSM-IV diagnosis of schizophrenia, schizoaffective disorder or bipolar disorder. Method: Using the Structured Clinical Interview for DSM-III-R (SCID), 100 consecutive inpatients with a psychotic disorder were examined for the presence or absence of an anxiety disorder. Questionnaire measures of phobias, obsessive-compulsive and general anxiety symptoms were also applied. Results: The prevalences of social phobia (17%), obsessiv-ompulsive disorder (13%) and generalised anxiety disorder in schizophrenia were relatively high, as were prevalences of obsessive-compulsive (30%) and panic disorder (15%) in bipolar disorder. The proportion of subjects with an anxiety disorder (4345%) was almost identical across the three psychoses, with some evidence of gender differences. Although self-ratings of overall psychiatric symptoms were significantly elevated in those with anxiety disorders, hospital admission rates were not. Conclusions: Almost none of those with anxíeGty disorders were being treated for them, primarily because the severity of the acute psychotic illness required full diagnostic and therapeutic attention. Patients were generally discharged as soon as their psychotic episode was resolved, with little recognition of the presence of an anxiety disorder. Given that anxiety disorders are relatively responsive to treatment, greater awareness of their comorbidity with psychosis should yield worthwhile clinical benefits.

AbstractPurposePsychometric properties and clinical sensitivity of brief self-rated dimensional scales to supplement categorical diagnoses of anxiety disorders in the DSM-5 were recently demonstrated in a German treatment seeking sample of adults. The present study aims to demonstrate sensitivity of these scales to clinical severity levels.MethodsThe dimensional scales were administered to 102 adults at a university outpatient clinic for psychotherapy. Diagnostic status was assessed using the Munich-Composite International Diagnostic Interview. To establish a wide range of clinical severity, we considered subthreshold (n= 83) and threshold anxiety disorders (n= 49, including Social Phobia, Specific Phobia, Agoraphobia, Panic Disorder, and Generalized Anxiety Disorder).ResultsIndividuals with either subthreshold or threshold anxiety disorder scored higher on all dimensional scales relative to individuals without anxiety. In addition, individuals with a threshold anxiety disorder scored higher on the dimensional scales than individuals with a subthreshold anxiety disorder (except for specific phobia). Disorder-related impairment ratings, global functioning assessments and number of panic attacks were associated with higher scores on dimensional scales. Findings were largely unaffected by the number of anxiety disorders and comorbid depressive disorders.ConclusionThe self-rated dimensional anxiety scales demonstrated sensitivity to clinical severity, and a cut-off based on additional assessment of impairment and distress may assist in the discrimination between subthreshold and threshold anxiety disorders. Findings suggest further research in various populations to test the utility of the scales for use in DSM-5.
