Premenstrual exacerbation (PME): when your cycle makes existing conditions worse

What PME means

PME doesn't add new symptoms. It turns up the volume on existing ones during the luteal phase, and they usually ease back toward your baseline once your period starts. Someone with depression might go from a manageable low to a much darker place for a week each month. Someone with ADHD might find their focus and emotional regulation collapse before every period.

PME isn't yet a formal diagnosis in the DSM-5, which is part of why it's so often missed. But it's well described in research and recognized by specialists, including the International Association for Premenstrual Disorders (IAPMD).

Conditions PME can affect

IAPMD lists a wide range, including:

• Major depression and persistent depressive disorder
• Generalized anxiety and other anxiety disorders, including panic
• Bipolar disorder
• ADHD (see ADHD and your menstrual cycle)
• PTSD and borderline personality disorder
• OCD, eating disorders and alcohol use disorder
• Suicidality
• Chronic pain conditions, migraine and epilepsy are also known to vary with the cycle

How common is PME?

A 2021 review found that around 60% of women with mood disorders report premenstrual worsening. IAPMD notes that nearly half of people seeking care for PMS or PMDD actually have PME or another underlying condition. In other words, if you have depression or anxiety and feel your period makes it worse, you're in the majority, not an exception.

PME vs PMDD

The two can also co-occur: someone can have depression all month and PMDD on top. Only a careful daily record can untangle that. Read more in PMS vs PMDD.

How PME is identified

There are no lab tests. IAPMD recommends daily symptom tracking over at least two cycles, using a tool like the DRSP. The clue is a chart where symptoms are there across the whole cycle but rise in the luteal phase, rather than a chart that's clean after your period and spikes before it.

Your baseline matters as much as your worst days

Because Lulu's check-in is one tap, it's easy to keep logging on ordinary days, which is exactly what shows PME. After two cycles, the PMS chart lines up your mood and symptoms by cycle day, ready to export for your doctor. Lulu doesn't diagnose; it helps you show the pattern.

Tips for tracking PME

• Rate your mood every day, not just on bad days. PME shows up as a raised baseline plus a premenstrual climb.
• Add one or two symptoms specific to your condition, like panic, focus or urges, so you can see whether those rise too.
• Note medication changes and big life events, which can otherwise be mistaken for cycle effects.

Treatment for PME

Evidence is still limited, and IAPMD notes there's currently no treatment developed specifically for PME. Current approaches focus on the underlying condition:

• Optimizing treatment for the main condition, for example ongoing antidepressants for depression.
• Luteal-phase adjustments: some clinicians increase a dose in the premenstrual week. A review found this approach has the most support so far, though based on small studies.
• Planning ahead: extra therapy sessions, check-ins and a safety plan for luteal weeks.
• Caution with PMDD-specific treatments: studies suggest hormonal options that help PMDD often work less well for PME of depression, and chemical or surgical menopause doesn't treat PME.
