History of perinatal complications (PCs) and first degree family history (FH) of psychiatric illness were examined in groups of schizophrenic/ schizoaffective (n = 21) and bipolar (n = 10) patients. PCs were significantly more frequent in the schizophrenic and schizoaffective patients than in bipolar patients. An inverse relationship was found between PCs and FH status, with FH-positive patients having significantly fewer PCs than the FH-negative group. This relationship persisted when the bipolar patients were excluded. Findings emphasize the etiological importance of genetics and perinatal events in the psychoses, and support the validity of a familial/sporadic distinction.
