# Are PMS and PMDD the same condition or are they different?

They are different. PMDD is more severe and causes significant distress and impairment in work and relationships, while PMS is broader and milder. PMDD requires more intensive treatment.

 Moderate study design

8,542 subjects across 25 Indian studies (from cited meta-analysis)

## What they did

Editorial commentary discussing diagnostic differences between PMS and PMDD, citing a systematic review and meta-analysis of 25 Indian studies involving 8,542 subjects total.

## What they found

From Indian studies: PMS prevalence 43%, PMDD 8%. PMDD involves mood, physical, or cognitive symptoms during most menstrual cycles, starting days before menses. Symptoms include mood swings, feeling low, worried, irritable, joint aches, and increased appetite or sleep. PMDD causes significant distress and work or personal impairment. PMS is broader and may not be disabling. PMDD has distinct biological mechanisms including hormonal sensitivity and neurotransmitter dysregulation.

## What it means for you

PMS and PMDD are separate conditions needing different approaches. PMDD needs intensive treatment like SSRIs or hormonal medications, while PMS may not. The underlying difference is severity and impact on functioning. Main limitation: this is an editorial based on other studies, not new research.
