title: Prevalence of obsessive-compulsive disorder in schizophrenia and significance of motor symptoms.
abstract: To investigate the differences between schizophrenic subjects with and without obsessive-compulsive disorder (OCD), the authors systematically assessed 76 schizophrenic subjects for OCD. Subjects with and without OCD were then compared with regard to motor symptoms, including catatonia, and several measures of psychopathology. Treatment strategies were evaluated retrospectively. The 12 subjects with OCD (15.8%) had more motor symptoms, including catatonia, than non-OCD schizophrenic subjects. Some differences were found with regard to psychopathological symptoms. Treatment strategies also differed in the two groups. The high prevalence of motor symptoms in these subjects supports the hypothesis of a basal ganglia-frontal lobe connection linking OCD with schizophrenia.
