If you have ADHD, your perimenopause might already be underway in your late 30s and nobody told you.
A new study followed over 5,300 women, ages 35 to 55, in Iceland. Women with ADHD hit peak perimenopausal symptoms between 35 and 39. Women without ADHD didn't peak until 45 to 49, a full decade later. And 54% of women with ADHD reported debilitating symptoms, versus about a third of women without it.
Quick science note: this is a cross-sectional, self-reported study in a fairly homogeneous population, so it shows a strong association, not proof of cause. I'd rather tell you that than oversell it.
Here's why it happens. Estrogen isn't just reproductive, it stabilizes dopamine, the same chemical behind focus and impulse control. In perimenopause that supply starts flickering. If your dopamine system was already thin because of ADHD, that flicker doesn't feel like an inconvenience. It feels like everything falling apart at once.
I see it constantly: women whose coping systems worked for 20 years suddenly stop working, and they think they're failing. They're not. Their hormonal floor moved.
If this is you, don't just adjust your ADHD management, get your hormones evaluated too. Book a discovery call and let's look at the whole picture.
