NIH-funded research R01 grant

Investigating hormone fluctuations and brain receptor changes in women with severe premenstrual symptoms

Official title: 1/2 Allopregnanolone and Dynamic GABA-A Receptor Plasticity in Selective Serotonin Reuptake Inhibitor Responsive Premenstrual Dysphoric Disorder

Funded at Johns Hopkins University · NIH-10975641 · Data updated 2026-11-12

This study is looking at how a low-dose medication called an SSRI can help women with premenstrual dysphoric disorder (PMDD) by understanding how it works with certain hormones and brain receptors during their menstrual cycle.

Who could benefit from this research

Could help

Ideal candidates for this research are women diagnosed with premenstrual dysphoric disorder who have regular menstrual cycles.

Less likely to help

Patients who do not have PMDD or those with irregular menstrual cycles may not benefit from this research.

What this research studies

This research focuses on premenstrual dysphoric disorder (PMDD), a severe condition affecting many women due to hormonal changes during the menstrual cycle. The study will explore how low-dose selective serotonin reuptake inhibitors (SSRIs) interact with specific brain receptors and hormones, particularly allopregnanolone, to understand their effects on PMDD symptoms. By examining the fluctuations of neuroactive steroids and their impact on GABA-A receptors, the research aims to clarify the mechanisms behind PMDD and the effectiveness of SSRIs. Participants will be women with regular menstrual cycles, and the study will involve assessments during the luteal phase of their cycles.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options and a better understanding of PMDD, potentially enhancing the quality of life for affected women.

How similar studies have gone: Previous research has shown promise in understanding hormonal influences on mood disorders, suggesting that this approach could yield valuable insights.
