Developmental disorder, Tourette disorder and schizophrenia: a case study.

We present a unique case of an 18-year-old male who had a classic picture of schizophrenia preceded by a well documented history of Tourette Disorder and a developmental disorder. The subject, a member of an ongoing study on first-admission psychosis, has been systematically evaluated and followed up for two years, and the interesting neuropsychological findings are presented and compared to those of the rest of the sample with a diagnosis of schizophrenia. The triad of schizophrenia, Tourette Disorder and developmental disorder is described for the first time in a subject with an adult type schizophrenia. Possible neurodevelopmental impairments explaining the clinical picture are discussed in view of the recent literature.
