The recent inclusion of Premenstrual Dysphoric Disorder (PMDD) in DSM-5 has been challenged from multiple angles. The main criticisms point to flaws in the validity of PMDD, as well as the potential for pathologizing and stigmatizing the physical and behavioral changes experienced by women during their premenstrual phase. To shed light on this controversy, I borrow some tools from the conceptual framework of epistemic injustices (EI) developed by Miranda Fricker. Specifically, I will build on recent work that has attempted to apply this framework to the categorization processes in medicine and psychiatry. This will allow me to uncover a blind spot in the current debate on PMDD, namely the perspectives of those affected by these symptoms. These views have generally been overlooked, but the EI framework allows us to refocus the debate on the interests and needs of those affected by psychiatric categorization processes.
