Prevalence, comorbidities and mediators of childhood anxiety disorders in urban Turkey: a national representative epidemiological study.

PURPOSE: The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children. METHODS: This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years. RESULTS: The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis. CONCLUSION: Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment.

BDNF Val66Met polymorphism is associated with negative symptoms in early-onset schizophrenia spectrum and other psychotic disorders

Abstract Background and Objectives. To investigate the clinical characteristics of adolescents with early-onset full psychotic disorders either with Brain-derived neurotrophic factor (BDNF) Val66Met (rs6265) or DRD2/ANKK1 Taq1A (rs1800497) polymorphisms.

Aripiprazole in children and adolescents with conduct disorder: a single-center, open-label study.

OBJECTIVE: The aim of this study was to determine the eff ectiveness and safety of aripiprazole in children and adolescents with both attention deficit/hyperactivity disorder (ADHD) and conduct disorder (CD). METHODS: 20 children and adolescents, ranging in age from 6­16 years, participated in a singlecenter, open-label study (19 to completion). We began treating patients with 2.5 mg of aripiprazole in an open-label fashion for 8 weeks. Outcome measures included the Turgay DSM-IVbased child and adolescent behavior disorders screening and rating scale (T-DSM-IV), the clinical global impressions-severity and improvement scales (CGI-S and CGI-I), the child behavior checklist (CBCL), the teachers report form (TRF) and the extrapyramidal symptom rating scale (ESRS), along with laboratory assessments. RESULTS: The mean daily dosage of aripiprazole at the end of 8 weeks was 8.55 mg (SD = 1.73), with a maximum dosage of 10 mg. Based on the global improvement subscale of the CGI, we classified 12 of 19 patients (63.1 %) as responders (very much or much improved). We observed significant improvements after aripiprazole treatment with regard to inattention, hyperactivity/impulsivity, ODD, and CD subscales of the T-DSMIV (parent, teacher and clinician forms). We also observed significant improvements on many of the CBCL and TRF subscales (e. g., attention problems as well as delinquent and aggressive behavior). The participants tolerated aripiprazole, and no patient was excluded from the study because of adverse drug events. CONCLUSION: Aripiprazole is an eff ective and well-tolerated treatment for ADHD and CD symptoms; however, additional studies (specifically, placebo-controlled and double-blind studies) are needed to better defi ne the clinical use of aripiprazole in children and adolescents with ADHD-CD.
