Objective: To compare parental psychopathology and psychiatric disorders in ADHD children with and those without enuresis. Method: The participants of the clinical sample interviewed according to "DSM-IV" diagnostic criteria were 35 children with ADHD and enuresis, 153 ADHD children without enuresis, 115 fathers, and 172 mothers. Results: Only ODD comorbidity was the predictor of enuresis. Conduct disorder, tic disorder, major depressive disorder, separation anxiety disorder, bruxism, generalized anxiety disorder, obsessive compulsive disorder, and nail biting were not statistically more frequent in ADHD children with enuresis than in the ADHD children without enuresis. The only parental psychiatric disorder that was related to the groups was father's major depressive disorder. Conclusion: Enuresis in ADHD has a relationship with ODD. Physicians who treat patients with ADHD and enuresis should routinely inquire about the presence of major depression in the fathers. (Contains 3 tables.)
