Psychoses of Epilepsy: A Radiological Evaluation

Abstract

SummaryComputerized axial tomography (CAT) scanning was carried out on 57 patients who had received a hospital diagnosis of psychoses associated with epilepsy, and 78 epileptic patients with psychiatric illness other than epilepsy. Abnormal scans were reported in approximately half of the cases in both groups. An excess of left hemisphere abnormality was noted in the psychotic group, but this was not significant. These findings failed to provide firm support for the hypothesis that lateralized structural damage to the cerebral hemispheres plays a major part in determining the specific pattern of associated psychotic illness.
