History of obstetric complications, family history, and CT scan findings in schizophrenic patients.

It has been proposed that obstetric complications (OCs) are more common in patients with nonfamilial schizophrenia, and associated with lateral ventricular enlargement in such patients. We examined the relations among OCs, family history of schizophrenia or bipolar mood disorder, and lateral ventricular size and cortical sulcal prominence in 44 schizophrenic patients. A history of OCs was not related to an absence of a family history of schizophrenia, ventricle-brain ratio, or cortical sulcal prominence. None of the CT findings was related to family history.
