AI Summary

A study published in Nature Communications found that premenstrual dysphoric disorder (PMDD) does not follow a single symptom pattern but can be divided into three distinct subtypes, each showing different symptom trajectories. Researchers arrived at this classification by analyzing symptom diaries, noting that PMDD symptoms typically begin shortly after ovulation and persist until menstruation starts. The authors suggest that recognizing these subtypes could enable more individualized treatment approaches for women experiencing this severe form of premenstrual syndrome.
