Risk factors for developing atypical (schizophreniform) psychosis following stroke

Five patients who developed an atypical schizophreniform psychosis
following right hemisphere stroke are described and compared to five
patients matched for lesion size and location who did not develop any
psychopathology after stroke. The patients who developed the
schizophreniform illness had a larger frontal horn ratio and larger third
ventricle ratio on CT head scans than did the comparison group. This
finding suggests that preexisting subcortical atrophy and a right
hemisphere lesion location are risk factors for developing schizophreniform
disorder following stroke.
