The course of psychosis in early phases of schizophrenia.
To study the course of psychosis in early schizophrenia, the authors assessed 111 patients at hospitalization and at one or two follow-ups. The course of psychosis was analyzed separately for broad (DSM-II) and narrow (DSM-III) concepts of schizophrenia. The patients diagnosed with DSM-II improved in psychosis between the first and second follow-ups. Those also diagnosed with DSM-III showed more persistent psychosis; 40% were psychotic at both follow-ups. A subgroup of patients showed improvement in psychosis even after several years of sustained symptoms. The authors discuss the implications of the data for views about the persistence of psychotic symptoms.
