Premenstrual dysphoric disorder (PMDD) is a severe mood disorder affecting 3-8% of women and individuals assigned female at birth, leading to debilitating symptoms before menstruation. Those with PMDD are at a significantly increased risk of suicide, with studies showing they are seven times more likely to attempt suicide compared to those without the disorder. The majority experience suicidal thoughts, and one in three have attempted suicide. Despite the serious implications, PMDD often goes under-diagnosed and mismanaged. To address this, researchers from the University of St Andrews, University of Glasgow, and University of the West of Scotland have developed a new model to aid healthcare professionals in understanding the relationship between PMDD and suicide risk. This model emphasizes the importance of menstrual cycle tracking, allowing for better risk assessment and patient interaction. The aim is to identify patterns of suicidality linked to hormonal fluctuations and improve care for those suffering from PMDD. The need for dedicated PMDD-specific suicide prevention interventions remains critical, as existing treatments may not adequately address the unique challenges faced by these individuals.
