Overview
The ‘IMV-PMDD Model’: a new framework to advance understanding of PMDD and suicidality
Webinar key points:
Suicide prevention is a priority area for PMDD stakeholders, including those who live with PMDD, and their loved ones, clinicians, researchers and support organisations.
Our new model identifies PMDD-specific factors that advance our understanding of suicidality, including phase of the menstrual cycle, hormonal ‘triggers’, neurodivergence and more.
The new IMV-PMDD model provides a framework to enhance the quality of screening, assessment and management of those living with heightened PMDD-suicide risk.

Alongside Julie Riddell, they led the development of the UK PMDD Research Agenda, and led the development of the IMV-PMDD model, a new evidence-based framework for understanding suicide risk in people with PMDD. Her programme of research also spans PMDD and disordered eating, parenting, welfare, and hormonal trigger events. Lynsay is a Trustee of IAPMD UK and sits on the NIHR's Women's Mental Health working group and the Scottish Government's Health of Women and Girls Research Network.
