Psychosis associated with demonstrable brain disease

Abstract

Sixty-five psychotic patients with unequivocal evidence of brain pathology and a variety of neurological disorders were assessed with respect to phenomenology and outcome. No relationship was found between site of brain pathology and type of psychotic disorder. A majority of patients had a syndrome indistinguishable from schizophrenia without coarse brain involvement and shared similar variables predicting outcome of psychosis, thus raising important issues concerning their nosological status.
