Should stressful life events be monitored after a first episode of psychosis?

Abstract

In the 3 years following a first episode of psychosis, 50% of individuals will experience a relapse, which could be expressed as symptom exacerbation or readmission to a psychiatric inpatient unit. 1 Alvarez-Jimenez M Priede A Hetrick SE et al.

Schizophr Res. 2012; 139: 116-128 Crossref PubMed Scopus (312) Google Scholar Hence, finding the relevant risk factors for new episodes is an urgent matter in psychiatric research and clinical practice. Whereas risk factors such as substance misuse and non-adherence to medication are well understood and can be targeted by interventions, less is known about other factors that might also be important, such as sleep deprivation, depressive or manic symptoms, or stressful life events. 1 Alvarez-Jimenez M Priede A Hetrick SE et al.

Stressful life events and relapse of psychosis: analysis of causal association in a 2-year prospective observational cohort of individuals with first-episode psychosis in the UKThese results provide converging evidence of a causal effect of stressful life events on the risk of relapse in psychosis. They suggest that there is a need to develop interventions at the individual and health-service level that could mitigate the harmful effects of stressful life events. Full-Text PDF Open Access
