First-episode psychosis

Abstract

Psychosis in the schizophrenia spectrum constitutes a major public health problem. There is convincing evidence for positive effects of 2-year specialized early intervention programs with intensive care, assertive outreach, and family involvement. Follow-up studies indicate a risk of loss of positive clinical effects after termination of specialized programs, but clinical effects can be sustained or even improved with prolonged specialized treatment or transfer to standard treatment, including assertive community treatment (ACT) for the most disabled patients. Long-term studies show substantial heterogeneity in clinical and functional outcomes, resulting in a very diverse picture. Ten-year follow-up studies of the OPUS and the AESOP cohort indicate that more than half of the patients will achieve stable remission of psychotic symptoms and that half of those patients can maintain remission in the long run without antipsychotic medication.
