OBJECTIVE To review implications of genetic research in child psychiatry. METHOD Key advances in quantitative and molecular genetics are noted and findings are summarized with respect to autism, attention-deficit hyperactivity disorder, oppositional defiant and conduct disorders, depression, schizophrenia, and Tourette's syndrome. CONCLUSIONS Genetic findings will be helpful clinically in t...

Oppositional Defiant Disorder (ODD) is a disruptive behavioural disorder in which child displays pattern of an angry mood, defiant or combative behaviour, and vindictiveness toward people authority. The child's behaviour often disrupts their daily routine, including activities within the family at school.

The study examined the association between low birth weight (LBW) (< or = 2,500 g) and attention deficit hyperactivity disorder (ADHD) in two socioeconomically disparate populations. LBW and normal birth weight (NBW) children from the 1983 to 1985 newborn lists of an urban and a suburban hospital in Southeast Michigan were randomly selected. A total of 823 children, 473 LBW and 350 NBW, partici...

Oppositional, defiant, and disruptive behaviors are common in clinical samples of children with tic disorders. In this study, we sought to evaluate the short-term efficacy of a structured parent training program in children with tic disorders accompanied by disruptive behavior. Children with tic disorders and at least a moderate level of disruptive behavior were randomly assigned to a 10-sessio...

Polymorphisms of three different dopaminergic genes, dopamine D2 receptor (DRD2), dopamine beta-hydroxylase (D beta H), and dopamine transporter (DAT1), were examined in Tourette syndrome (TS) probands, their relatives, and controls. Each gene individually showed a significant correlation with various behavioral variables in these subjects. The additive and substractive effects of the three gen...

Oppositional defiant disorder (ODD) is a frequent psychiatric disorder seen in children and adolescents with attention-deficit-hyperactivity disorder (ADHD). ODD is also a common antecedent to both affective disorders and aggressive behaviors. Although the heritability of ODD has been estimated to be around 0.60, there has been little research into the molecular genetics of ODD. The present stu...

BACKGROUND The aim was to study the comorbidity of oppositional defiant disorder (ODD) and anxiety disorders (AD) among preschool children of the general population, and to assess the contribution of comorbidity to the child's functional impairment. METHOD 622 children were assessed at the ages of 3 and 5, through a diagnostic interview. They were clustered into three diagnostic groups: only ...

OBJECTIVES To identify age-related trajectories of obesity from childhood into adolescence, and to test the association of these trajectories with the development of psychiatric disorders (conduct disorder, oppositional defiant disorder, attention-deficit/hyperactivity disorder, substance abuse, depression, and anxiety). METHODS White children (N = 991) 9 to 16 years old from the Great Smoky ...
