What is premenstrual exacerbation (PME)?
Premenstrual exacerbation (PME) is the worsening of an existing condition, such as depression, anxiety, bipolar disorder, ADHD, migraine or epilepsy, in the days before a period. Unlike PMDD, symptoms are present across the whole cycle but get stronger in the late luteal phase. It is common and often overlooked, yet treatment can be adjusted to it.
PME vs PMDD
| PMDD | PME | |
|---|---|---|
| Symptoms after the period | Mostly gone in the follicular phase | Still present, just milder |
| Underlying condition | No | Yes, all cycle long |
| Pattern | On and off with the cycle | Background condition, turned up before a period |
Daily tracking is the best way to tell them apart. If your mood never fully clears in the week after your period, PME is more likely than PMDD. Some people have both.
Conditions that often show PME
- Depression and anxiety disorders
- Bipolar disorder
- ADHD, with harder focus and more emotional reactivity before a period
- Eating disorders
- Migraine and epilepsy
What helps
Tell your doctor about the cyclical pattern. Some people benefit from a higher dose of their usual medicine in the late luteal phase, from hormonal treatment to steady the cycle, or from extra therapy support at that time. Read the full guide to PME and ADHD and the menstrual cycle.

Frequently asked questions
How do I know if I have PME or PMDD?
Track mood daily for two cycles. If symptoms clear after your period, it points to PMDD; if they stay but ease, PME is more likely.
Is PME a recognized diagnosis?
It isn't a separate diagnosis in the DSM-5, but doctors and researchers widely use the term to describe this pattern.
