Recent Insights in the Treatment for Clinical High Risk for Psychosis and Recent Onset Psychosis

Abstract

Objectives: This study aims to assess the effectiveness of early interventions in preventing psychosis transition, promoting remission, and reducing hospitalization rates in individuals at high risk for psychosis and those with recent onset psychosis (ROP).Methods: A systematic review and meta-analysis were conducted, comparing early intervention strategies such as cognitive-behavioral therapy and psychosocial support to no intervention. The study focused on outcomes related to psychosis transition, remission rates, and prevention of psychiatric hospitalization.Results: Although only a subset of clinical high risk (CHR) individuals transition to full psychosis, non-pharmacological treatments like cognitive-behavioral therapy are generally recommended as a first-line approach. In ROP patients, early pharmacological treatment reduces relapse rates, while psychosocial interventions aim to improve various functional outcomes. The meta-analysis results of this study did not show a significant reduction in psychosis transition rates with specialized interventions for CHR patients. For ROP patients, early interventions initially reduced hospitalization rates, but this effect was not sustained in mid-term follow-up results.Conclusion: While early interventions offer short-term benefits in reducing psychosis transition and hospitalization, additional research is needed to determine their long-term effectiveness in functional recovery and overall patient outcomes.
