Have you noticed your levels of attention may slightly change during your menstrual cycle? This may be particularly noticeable for women and people assigned female at birth with attention deficit hyperactivity disorder (ADHD). They have differences in their ability to easily focus and sustain their attention. There may be times during their menstrual cycle when it seems harder to plan, organise and focus their attention. And they may find their ADHD medication doesn't seem to work as well. Very little research has explored the interaction between female hormones and symptoms of ADHD .
