Cohort study design
Analysis of all-cause and cause-specific mortality
Consideration of familial factors
Bipolar II disorder patients exhibited a significant risk of premature mortality
All-cause mortality remained higher even when comparing with bipolar I disorder

Abstract

In this cohort study, BD-II was associated with a significant risk of premature mortality across multiple causes; even after accounting for shared familial factors and relative to BD-I, all-cause mortality remained elevated. These findings underscore the importance of comprehensive psychiatric care for individuals with BD-II.
