Jordan W Smoller
Anxiety disorders are the most common class of psychiatric disorders and incur an enormous burden in terms of economic costs, disability and personal suffering. Despite their public health importance and documented heritability, genetic research aimed at identifying the genetic contributions to these disorders has had limited success, particularly in comparison to recent advances in the genetics of other major psychiatric disorders. The major factor contributing to this lagging progress has been a dearth of well-powered genomic studies...

OBJECTIVES: The number of children in the United States utilizing emergency department (ED) services for psychiatric crises is increasing, and psychiatric-related ED visits disproportionately burden hospital resources. Yet, there is limited available information on the epidemiology and outcomes of pediatric mental health emergencies. The present study sought to characterize pediatric mental health-related ED presentations in a large urban center and identify factors predictive of inpatient hospitalization...

Cannabis use has been reported to affect the course of various psychiatric disorders, however its effect on the course of major depressive disorder (MDD) is not yet clear. We used data from Wave 1 and Wave 2 of the National Epidemiologic survey on Alcohol and Related Conditions (NESARC). Individuals with baseline MDD (N=2,348) were included in the study. Cannabis users without a Cannabis Use Disorder (CUDs) and individuals with a CUD were compared to nonusers using linear and logistic regression analyses controlling for sociodemographics, psychiatric disorders and substance use disorders at baseline...

Cancer patients are at high risk for suicide, particularly when they are informed about the cancer diagnosis or hospitalized for cancer treatment. Therefore, oncology healthcare settings such as large general hospitals in China, may represent an ideal setting to identify and treat suicidality in cancer patients. However, the clinical epidemiology of suicidality of Chinese cancer patients remains largely unknown. This study examined the prevalence and correlates of suicidal ideation among Chinese cancer inpatients of large general hospitals...

Inflammatory bowel disease is a group of chronic medical conditions comprising Crohn's disease and ulcerative colitis that involves increased frequency of mental disorders. The most common psychiatric disorders in inflammatory bowel disease are depression and anxiety, however, some epidemiologic and biological evidence suggest that other disorders like bipolar disorder occur more often. Biological mechanisms concerning both inflammatory bowel disease and depression or anxiety explain susceptibility to developing mental disorders in inflammatory bowel disease...

PURPOSE: There is a need to better understand the epidemiological relationship between language development and psychiatric symptomatology. Language development can be particularly impacted by social factors-as seen in the developmental choices made for deaf children, which can create language deprivation. A possible mental health syndrome may be present in deaf patients with severe language deprivation. METHODS: Electronic databases were searched to identify publications focusing on language development and mental health in the deaf population...

Major Depressive Disorder (MDD) and Nicotine dependence (ND) often co-occur. However, little attention has been given to the temporal order between the two disorders. We compared the sociodemographic and clinical characteristics of individuals whose onset of ND preceded (ND-prior) or followed the onset of MDD (MDD-prior). Binary logistic regression models were computed to compare ND-prior (n=546) and MDD-prior (n=801) individuals from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, n=43,093)...

PURPOSE: The course of conduct disorder (CD) is heterogeneous. Moffitt proposed the heuristic of life course persistent (LCP) and adolescence limited (AL) to differentiate etiologically distinct forms of antisocial behavior (AB), each with distinct predictors and consequences, although a few studies have assessed this demarcation within the context of CD. The objective of this study was to apply Moffitt's taxonomy in a nationally representative US sample to investigate the prevalence, predictors, and outcomes of LCP and AL CD...

BACKGROUND: Males are diagnosed with dyslexia more frequently than females, even in epidemiological samples. This may be explained by greater variance in males' reading performance. METHODS: We expand on previous research by rigorously testing the variance difference theory, and testing for mediation of the sex difference by cognitive correlates. We developed an analytic framework that can be applied to group differences in any psychiatric disorder. RESULTS: Males' overrepresentation in the low performance tail of the reading distribution was accounted for by mean and variance differences across sex...

BACKGROUND: Prolonged grief disorder (PGD) is a bereavement-specific syndrome expected to be included in the forthcoming ICD-11. Defining the prevalence of PGD will have important nosological, clinical, and therapeutic implications. The present systematic review and meta-analysis aimed to estimate the prevalence rate of PGD in the adult bereaved population, identify possible moderators, and explore methodological quality of studies in this area. METHODS: A systematic literature search was conducted in PubMed, PsycINFO, Embase, Web of Science, and CINAHL...

BACKGROUND: Insomnia symptoms are common in the population and have negative psychosocial and functional sequelae. There are no prospective studies of the course of such symptoms and their impact, if any, in stroke survivors. This prospective cohort study investigated insomnia after stroke in working-age adults and evaluated its impact on psychological and functional outcomes over the subsequent year. METHODS: We prospectively recruited 441 young (<65 years) consecutive stroke survivors from 20 public hospitals in the New South Wales Stroke Service network...

PURPOSE OF REVIEW: To review some aspects of the relationship between epilepsy and depression that have recently received increasing attention and may become major research topics in the near future. RECENT FINDINGS: Epidemiological studies show that depression and suicide are, in some cases, premorbid symptoms preceding the onset of the epilepsy. Suicide is also three times more frequent in epilepsy than in the general population. Reliable screening instruments for depression and suicidality in patients with epilepsy are now available but data from real life clinical settings are needed to develop shared clinical pathways between neurology and psychiatry...

Hallucinations are classically associated with psychotic disorders. Recent research, however, has highlighted that hallucinations frequently occur outside of the context of psychosis. Despite this, to our knowledge, there has been no epidemiological research to compare the prevalence of hallucinations across common mental disorders with the prevalence in borderline personality disorder (BPD). Using data from the Adult Psychiatric Morbidity Survey (n = 7403), we investigated the prevalence of hallucinations in individuals with a range of mental disorders and BPD...

Growing evidence from epidemiological studies strongly suggests maternal infection as a risk factor for psychiatric disorders including bipolar disorder, schizophrenia, and autism. Animal studies support this association and demonstrate that maternal immune activation (MIA) changes brain morphology and inflammatory cytokines in the adult offspring. Evidence for changes in inflammatory cytokines is also demonstrated in human post-mortem brain and peripheral blood studies from subjects with psychiatric disorders...

BACKGROUND: Numerous suicide risk factors have been proposed but not adequately validated for epidemiology, treatment and prevention efforts. AIMS: Exposures to suicidal behaviors (ESB), from family and friend suicide attempts and completions, were tested for validity as a suicidal risk factor and also for measurement and construct adequacy. METHODS: An anonymous online survey yielded 713 participants (aged 18-71), who reported ESB, completed the Suicidal Affect-Behavior-Cognition Scale (SABCS), and comprised a broad spectrum on those variables...

INTRODUCTION: Studies about mental disorders are very rare in the Northeast of Brazil, especially when psychopathologies in children and adolescents are considered. The consequence is a small availability of data and an absence of a real epidemiological profile. METHODS: This is a systematic review with meta-analysis, following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol, in the period from 2003 to 2015, using the databases LILACS, SciELO and BVS...
