How do I know if this is PMS, PMDD, or something else?
Some conditions look like PMS. Some overlap with it. Some just make it worse. Here is what tells them apart.
Is it PMS, or something else
- moderate PMDD + ADHD
If you have ADHD, the week before your period can hit focus and motivation harder. That's the dopamine dip, not you slacking.
Up to ~46% of women with ADHD report PMDD; dopamine dip is the bridge; adolescent PMS-ADHD OR 2.43
- moderate PMDD safety
If the heavy feeling never fully lifts after your period, that's worth a proper look.
PME (depression/anxiety/bipolar worsening premenstrually) vs true PMDD (clears in follicular phase)
- moderate PCOD
PCOS and PMS aren't the same thing, but they can feed each other.
PCOS doesn't cause classic PMS (needs ovulation) but overlaps: insulin resistance + androgens drive mood/cravings
- weak PMS
Thyroid issues can look like PMS, so they're worth ruling out.
Thyroid dysfunction can mimic PMS (1986 finding; 1990 study failed to replicate)

Knowing why only helps if you can use it
