Kind: research · Impact: medium

## In brief

- A study in Nature Communications reports that premenstrual dysphoric disorder (PMDD) does not follow one universal symptom pattern.
- The study identifies three PMDD subtypes with different symptom patterns, based on symptom diaries.
- The research uses predictive symptom networks to examine how PMDD symptoms unfold over time and identifies anxiety as a key symptom.

## Why it matters

The finding that PMDD has distinct symptom subtypes suggests that a single diagnostic pattern may not fit all patients, which could matter for how the condition is studied and understood.
