Although the literature contains many reports of psychotic syndromes associated with brain lesions, there are relatively few systematic studies of patients with psychosis following stroke. Davison and Bagley (1968) reviewed 50 reports of schizophrenialike syndromes associated with disruption of normal brain anatomy or physiology. They concluded that no single type of brain injury or location was causally associated with these syndromes. Levine and Finkelstein (1982) and Price and Mesulam (1985) reported, however, that schizophrenia-like symptoms were strongly associated with right hemisphere infarctions as well as seizure disorders. Levine and Finkelstein (1982) reported on eight patients who developed hallucinations between 1 month and 11 years after a cerebrovascular infarction or traumatic brain injury. None of them had a previous personal history of psychiatric disorder and all of them were right handed. All of the patients had right hemisphere lesions with partial or complete involvement of the temporoparietal-occipital junction. The hallucinations and delusions developed acutely and lasted a period of days to months. In addition to the association with right hemisphere lesions, seven of the eight patients had seizures that developed after the brain injury: six of them had focal seizures while the remaining patient had generalized seizures. The seizures had preceded the onset of psychosis in five patients and followed the onset in the remaining two.
