Converging evidence identifies that the offspring of parents with bipolar disorder
(BD), individuals at clinical high risk of BD, and young people with recent onset
BD may differ from other clinical cases or healthy controls in terms of sleep-wake
profiles. However, it is possible that these differences may reflect current mental
state, subtype of mood disorder, or familial traits. This study aimed to determine
objective and subjective sleep-wake profiles in individuals aged 15-25 years with
a current major depressive episode, in relation to familial traits.
