The Evolution of Symptoms in Institutionalized Hebephrenic/Catatonic Schizophrenics

Abstract

SummaryThe charts of 52 hebephrenic/catatonic schizophrenics requiring long-term institutionalization were selected from the Iowa 500 study and reviewed. The presence or absence of 28 different symptoms was noted on a year by year basis over a span of 35 years. Symptoms usually classified as positive symptoms of schizophrenia, such as hallucinations and delusions, were found to have earlier onset and greater tendency to resolve over time than symptoms usually classified as negative such as flat affect, decreased social interaction and sensorium defects.
