Suicide Risk and the Menstrual Cycle: a Review of Candidate RDoC Mechanisms

Purpose of Review Risk for suicidal behavior may fluctuate across the menstrual cycle. Here, we use the RDoC framework to review potential mechanisms by which the cycle may increase acute suicide risk. Recent Findings The menstrual cycle impacts the majority of RDoC constructs linked to suicide risk, particularly among hormone-sensitive women, such as those with premenstrual dysphoric disorder or premenstrual exacerbation of a psychiatric disorder. Despite this, there are no published studies examining suicidal ideation, planning, or behavior longitudinally across the cycle. Summary More work is needed to understand how hormone sensitivity may relate to both trait and state suicide risk. Intensive multilevel investigations of cyclical hormone effects on suicide risk through specific RDoC mechanisms are suggested. This is a fertile research area and may provide key insights regarding the mechanisms of acute suicide risk.
