Cerebral Ventricular Enlargement in Non-Genetic Schizophrenia: a Controlled Twin Study

Abstract

Summary: In a group of schizophrenics of twin birth, no evidence of ventricular enlargement was found where there was a family history of major psychiatric disorder. Among those schizophrenics without such a family history, cerebral ventricular size was significantly increased (P <0.01), and there was also evidence of birth complications. Among normal control twins, those who reported complicated births had significantly larger ventricles.
