title: Established chronicity of psychotic symptoms in first-admission schizophrenic patients.
abstract: The course of schizophrenia before a patient's first admission is important theoretically, prognostically, and from a preventive psychiatric perspective. However, there is little systematically collected information on this topic. In this evaluation of a representative sample of first-admission schizophrenic patients, there was a wide variation in chronicity of psychotic symptoms before admission, with 20% of the patients having been symptomatic for more than 2 years and 28% for less than 1 week. Delusions of grandeur, delusions of reference, and suspiciousness were more common in the more chronic patients than in the most acute patients; symptoms of withdrawal and retardation showed the opposite pattern. The authors discuss the implications of these findings for prognosis, prevention, and theory.
