The proportion of people with primary affective disorders presenting to early intervention services: systematic review and meta-analysis

Listen to this summary

The authors aimed to determine the prevalence of primary affective disorders among individuals presenting to early intervention services (EIS) for first-episode psychosis. Through a systematic review and meta-analysis of 83 studies, they found that affective psychotic disorders accounted for 18.0% of presentations, with significant variations based on geographical region and urbanicity. The findings highlight the need for improved screening and tailored treatment approaches for this subgroup within EIS.
