New research suggests women with bipolar disorder and regular periods report higher rates of severe premenstrual distress, highlighting gaps in reproductive health care.

A study of 267 women of reproductive age with bipolar disorder found that those with regular menstrual cycles are more likely to report severe premenstrual symptoms than those with irregular cycles. The preliminary findings, presented at the 2026 ECNP Congress in Munich, indicate that these symptoms often include irritability, anger, and significant interference with daily activities.

Contraceptive Use and Sensitivity

The research revealed that women with regular cycles were less likely to use hormonal contraceptives compared to those with irregular cycles. While 93% of the total sample had tried hormonal birth control, a higher proportion of women with regular menstruation discontinued use due to side effects and expressed greater reluctance toward hormonal treatments. Lead researcher Dr. Sofie Ragnhild Aminoff noted that this suggests some women with bipolar disorder may be particularly sensitive to hormonal contraceptives.

Clinical Implications and Future Research

The study highlights a lack of clinical guidance for managing mood changes, psychotic symptoms, or suicidal thoughts that fluctuate with the menstrual cycle in patients with bipolar disorder. Researchers emphasize that premenstrual symptoms in this population are often not taken seriously, and there is a critical need for better collaboration between psychiatry and gynecology. The authors noted that these findings are preliminary, based on an online survey, and have not yet been submitted to a peer-reviewed journal.
