Where the overlap comes from
Both ADHD and anxiety can involve distractibility, restlessness, avoidance, forgetfulness, sleep disruption and difficulty completing tasks. The mechanisms may differ. Anxiety may pull attention toward threat or worry, while ADHD may involve difficulty regulating attention even when the person is not anxious.
Questions that help clarify the pattern
Was it there before anxiety?
Longstanding childhood patterns can be clinically informative when current stress has made everything worse.
What happens when calm?
If attention and organisation remain difficult during low-anxiety periods, that is useful information to bring to assessment.
What drives avoidance?
Fear of a bad outcome, boredom, uncertainty, task complexity and difficulty initiating can feel similar but may need different strategies.
Can both be true?
Yes. Co-occurring anxiety is common in people with ADHD, and treating only one part of the picture may leave important difficulties unchanged.
Do not self-diagnose from one distinction
No single online question reliably separates ADHD from anxiety. If symptoms are causing significant impairment, a qualified professional can consider both conditions and other explanations.
