Schizencephaly associated with bipolar affective disorder.

Schizencephaly is a rare congenital anomaly of the brain, characterized by formation of abnormal unilateral or bilateral clefts in the cerebral hemispheres. It often manifests with partial seizures, mental retardation and hemiparesis. Only two cases of schizencephaly associated with psychosis have been reported in the literature. A patient of schizencephaly, who had bipolar affective disorder is described. It has been compared with the earlier two reported cases of schizencephaly associated with pyschosis.
