Psychoses of epilepsy: a radiological evaluation
BK Toone, J Dawson and MV Driver
Computerized 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.
