Effect of Impairment on the Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder in a National Survey: Nation-Wide Prevalence and Comorbidities of ADHD.

Objective: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder (ADHD) by evaluating a large-scale nation-wide sample of children.

Method: The inclusion criterion was being enrolled as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842 participants.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

Aim: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey.

Method: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently.

Evaluation of the Relationship between Brain-Derived Neurotropic Factor Levels and the Stroop Interference Effect in Children with Attention-Deficit Hyperactivity Disorder.

Introduction: Brain-derived neurotropic factor (BDNF) has been suggested to play a role in the pathogenesis of attention-deficit hyperactivity disorder (ADHD). In addition, impairment in executive functions has been reported in children with ADHD. This study investigated the presence of a relationship between Stroop test scores and BDNF levels in children with ADHD.

Cortisol and ACTH levels in drug-naive adolescents with first-episode early onset schizophrenia.

The aim of this study was to investigate serum levels of cortisol and adrenocorticotropic hormone in adolescents with first-episode early onset schizophrenia. A total of 23 adolescent patients, who did not receive prior therapy and who were diagnosed with psychosis according to DSM-IV, were included. Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version, Positive and Negative Symptom Scale, and Clinical Global Impression Scale were conducted with the participants.

Cortisol and Brain-Derived Neurotrophic Factor Levels Prior to Treatment in Children With Obsessive-Compulsive Disorder.

Objective: In this study, we investigated serum brain-derived neurotrophic factor (BDNF), adrenocorticotropic hormone (ACTH), and cortisol levels between children with obsessive-compulsive disorder (OCD) prior to treatment and healthy controls. In addition, the study aimed to assess any correlations between OCD symptom severity and BDNF, ACTH, and cortisol levels.

Methods: Twenty-nine children, aged from 7 to 17 years (male/female: 21/8) and diagnosed with OCD according to DSM-IV prior to treatment, were compared with 25 healthy control subjects (male/female: 16/9).

Oxidative Stress and DNA Damage in Untreated First-Episode Psychosis in Adolescents.

Objective: Oxidative stress has been reported to play a role in the psychopathology of schizophrenia, though only a few studies have investigated the relationship between early-onset schizophrenia and oxidative stress. The aim of the present study is to evaluate the level of oxidative stress and the presence of DNA damage in first-episode psychosis (FEP) in adolescents.

Methods: This study was conducted in the Department of Child Psychiatry of the Dicle University Hospital.

DNA damage and antioxidants in treatment naïve children with obsessive-compulsive disorder.

The current study aimed to investigate whether serum antioxidant levels and DNA damage differ between the children and adolescents with Obsessive Compulsive Disorder (OCD) and healthy controls. The study included 31 children (Male/Female, 22/9; age range 7-17 years), with treatment naïve OCD diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-V (DSM-V) and 28 age- and gender-matched healthy control subjects. Children's Yale Brown Obsession Compulsion Scale (CY-BOC) was applied to the children.

Effects of Gluten-Free Diet on Quality of Life and Depression in Children With Celiac Disease.

Objectives: The aim of this study was to investigate the level of depression and quality of life in children with celiac disease (CD). In addition, it aimed to examine the relations of depression level and life quality with adherence to a gluten-free diet (GFD).

Methods: Twenty-five children with CD and 25 healthy controls were included.

Lower Brain-Derived Neurotropic Factor Levels in Untreated Adolescents With First-Episode Psychosis.

Objective: Brain-derived neurotropic factor (BDNF) is known to play a role in the pathogenesis of schizophrenia. However, the relationship between early onset schizophrenia and BDNF has not been extensively studied. The aim of the study was to compare the levels of BDNF between adolescent patients with first-episode psychosis (FEP) and the healthy control subjects.

Attachment styles and psychopathology among adolescent children of parents with bipolar disorder.

Background: The aim of this study was to compare attachment styles and psychopathology in adolescent children of parents with bipolar disorder (BD) with a healthy control group.

Material And Methods: We studied 25 adolescents who had at least 1 parent with BD (BD group) and 28 adolescents who had no parents with BD (control group). The adolescent participants were between the ages of 12 and 17 years.

Evaluation of adult attention deficit hyperactivity disorder in smokers and Maras powder users.

Background: The aim of this study was to evaluate adult attention deficit and hyperactivity disorder (ADHD) in smokers, Maras powder users and non-users of tobacco products by using the Adult Attention Deficit and Hyperactivity Disorder Self-report Scale (ASRS).

Methods: The study was performed on 446 males presenting to family health centers in Kahramanmara, Turkey. Of 446 participants, 104 were Maras powder users, 133 were smokers and 209 were volunteers not using any tobacco products.
