Comorbidity of autistic disorder in children and adolescents.

Although considerable research has been done on various aspects of autism, information about the prevalence of coincident psychiatric disorders that may complicate this syndrome, is negligible. In this paper, we present preliminary data on the presentation of other psychiatric disorders in children and adolescents with autism. Out of an outpaticent sample of 68 autistic children and adolescents, 6 (9%) presented with an associated psychiatric disorder. Depression was the most common diagnosis. None of the patients was given a diagnosis of schizophrenia. Clinical and research implications of the findings are discussed.
