What unanswered questions remain about ADHD biology and evolution?

Women with ADHD often experience symptom changes across the menstrual cycle due to fluctuations in estrogen, which affects dopamine regulation. Tracking symptoms can help identify patterns and guide treatment. This can be done by keeping a simple daily log that rates focus, impulsivity, emotional regulation, motivation, sleep, and anxiety, while also noting the phase of the menstrual cycle or days relative to the start of the period. Recording medication effectiveness, side effects, and wear-off timing is also helpful, along with tracking hormonal symptoms such as PMS, fatigue, mood changes, or headaches. Many women notice improved ADHD symptoms during the follicular and ovulatory phases and worsening during the late luteal and menstrual phases. This information allows clinicians to individualize treatment strategies and helps patients understand that symptom fluctuations are biologically driven, not a personal failure.
