Chronic psychosis in epilepsy

Abstract

A clinical study comprising psychiatric, psychological and neurological examination of 29 patients suffering from long-term psychosis and severe epilepsy was performed. Only five patients fulfilled the diagnostic criteria of schizophrenia. They differed from the rest of the patients by being less organic and having infrequent laterality to the left of their epileptogenic focus. They were regarded as genuine schizophrenics, while the pathogenesis of the remaining sample was considered multifactorial, including both organic and psycho-social causes.
