ADHD and Anxiety: Why They Often Show Up Together

Anxiety and ADHD frequently overlap, and research estimates a meaningful proportion of people with ADHD also experience clinically significant anxiety at some point. Some of this connection may be circumstantial — years of missed deadlines, forgotten commitments, or feeling "behind" can genuinely produce anxiety as a natural response — and some may share underlying biological threads that researchers are still working to fully understand.

This overlap matters practically because the two can mask or amplify each other. Racing thoughts at bedtime might be ADHD-driven mental restlessness, anxiety, or both at once — and the useful next step often depends on telling them apart, which is genuinely hard to do without support from a professional.

General stress-management tools (movement, consistent routines, reducing overall cognitive load) tend to help both, which is part of why they show up so often in ADHD-focused advice — not because they're a cure for either, but because they lower the overall load the nervous system is carrying.

If anxiety is a significant part of your experience, it's genuinely worth raising directly with a healthcare professional rather than assuming it's "just part of" ADHD — the two sometimes need different support, and getting an accurate picture helps target what actually helps.
