Childhood obsessive-compulsive disorder

The authors collected clinical diagnostic, neurophysiological, electrophysiological, and biochemical data on 9 adolescents who had primary obsessive-compulsive disorder. The results indicate considerable descriptive validity of the syndrome in childhood and its independence from obsessional traits; however, all of the children had a history of major depressive disorder, and their sleep EEG measures resembled those of young adults with primary depressive disorder. The patients' families did not have a more consistent pattern of anxiety disorder or any other psychiatric disorder than do families of adult obsessive patients. Psycholinguistic test results showed a lack of normal laterality, which has been reported for other psychiatric illness.
