Abstract:
This study examines the relationship between duration of untreated psychosis (DUP) and long-term symptomatic and social outcome in 205 patients with schizophrenia, whose parents are member of a consumer organisation. We found only a tendency that longer DUP was related to negative symptoms, but no relation to other outcome domains. The results of this study do not support antipsychotic intervention at the earliest sign of psychosis in order to 'protect the brain'.
