[Show abstract][Hide abstract] ABSTRACT: Premenstrual syndrome (PMS) affects up to 80% of women, often leading to significant personal, social and economic costs. When apparently maladaptive states are widespread, they sometimes confer a hidden advantage, or did so in our evolutionary past. We suggest that PMS had a selective advantage because it increased the chance that infertile pair bonds would dissolve, thus improving the reproductive outcomes of women in such partnerships. We confirm predictions arising from the hypothesis: PMS has high heritability; gene variants associated with PMS can be identified; animosity exhibited during PMS is preferentially directed at current partners; and behaviours exhibited during PMS may increase the chance of finding a new partner. Under this view, the prevalence of PMS might result from genes and behaviours that are adaptive in some societies, but are potentially less appropriate in modern cultures. Understanding this evolutionary mismatch might help depathologize PMS, and suggests solutions, including the choice to use cycle-stopping contraception.
[Show abstract][Hide abstract] ABSTRACT: The proposals to include a menstruation-related mood disorder in the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R), and DSM-IV led to intense public and behind-the-scenes controversy. Although the controversies surrounding the DSM-5 revision were greater in number than the controversies of the earlier revisions, the DSM-5 proposal to include a menstruation-related mood disorder was not among them. Premenstrual dysphoric disorder was made an official disorder in the DSM-5 with no significant protest. To understand the factors that led to this change, we interviewed those psychiatrists and psychologists who were most involved in the DSM-IV revision. On the basis of these interviews, we offer a list of empirical and nonempirical considerations that led to the DSM-IV compromise and explore how key alterations in these considerations led to a different outcome for the DSM-5.
