Anxiety and ADHD both produce fidgeting, distractibility, avoidance of work and difficulty sleeping. The most useful question is usually one of sequence: did the worry come first, or did years of struggling create it?
Distinguishing features
| Observation | Points towards ADHD | Points towards anxiety |
|---|---|---|
| Distraction | Pulled away by anything new or interesting | Pulled inward by worry about a specific thing |
| Situations | Fairly consistent across settings | Worse in specific, predictable situations |
| Avoidance | Avoids effortful or boring tasks | Avoids tasks with a risk of judgement or failure |
| Restlessness | Present most of the time, from early childhood | Rises and falls with the source of worry |
| Sleep | Cannot switch a busy mind off | Kept awake by specific fears |
| History | Present since early childhood | Often traceable to a period or event |
How the two reinforce each other
A common pathway when ADHD goes unrecognised.
Unrecognised ADHD
Repeated setbacks
Fear of failing again
Avoidance
Anxiety diagnosis
Why it matters which is which
Treating anxiety alone in a child whose ADHD is undiagnosed often produces limited progress, because the underlying source of the setbacks remains. Equally, addressing attention without acknowledging real anxiety leaves a child feeling unheard. A good assessment considers both.
What to tell your GP
- When each set of difficulties began, as precisely as you can.
- Whether the worry is about something specific or generalised.
- Whether concentration is poor even in relaxed, low-pressure moments.
- What school has observed, in their words.
Frequently asked questions
- Can anxiety look exactly like ADHD?
- It can look very similar in a classroom. The distinguishing information is usually the developmental history and whether difficulties are situation-specific.
- Can a child have both?
- Yes, and it is common. Anxiety frequently develops alongside unrecognised ADHD.
- Should we treat anxiety first?
- That is a clinical decision. Where ADHD is likely, assessing it rather than deferring it usually helps the anxiety work too.
