ADHD and PMDD: why symptoms spike before your period (and what helps)

Some weeks you can handle anything. Then, seemingly overnight, everything feels impossible. Your mood. Your focus. Your patience with yourself. If that shift keeps landing the same week of your cycle, it might not just be PMS.
In this episode, Dr. J — a licensed psychologist who works with people with ADHD — breaks down premenstrual dysphoric disorder. PMDD, a diagnosis recognized in the DSM-5-TR, goes well beyond typical PMS and shows up disproportionately in women with ADHD. Research suggests that 31–46% of women with ADHD also meet criteria for PMDD. And the overlap isn’t a coincidence. Both ADHD and PMDD are tied to dopamine regulation and sensitivity to hormonal shifts.
Dr. J walks through what actually separates PMDD from PMS and why it so often goes undiagnosed. She also looks at what’s happening in the brain during the luteal phase — including why your ADHD symptoms, and even your medication, can feel different that week. And she offers practical, evidence-based strategies to make PMDD more manageable, like:
Symptom tracking
Adjusting diet and exercise
Talking to your provider about medication timing
Planning your schedule around your cycle
Plus building the kind of self-compassion that makes hard weeks survivable instead of shameful.
If you’ve ever felt like you lose yourself for a week every month, this one’s for you.
