You can't concentrate. Your mind jumps from one thing to the next. You feel restless, you put things off, and you lie awake at night. Is that ADHD, anxiety, or both?
It's a genuinely tricky question, because the two can look remarkably similar from the outside. The difference often lies in why your attention slips and what is driving the restlessness. This guide breaks down the overlap, the key differences and what to do next.
Why ADHD and anxiety are so easy to confuse
ADHD is a neurodevelopmental condition that affects attention, activity levels, impulse control and executive function — the mental skills used to plan, start, organise and finish tasks. Anxiety disorders involve excessive, persistent worry or fear that is hard to control.
On paper they're different. In daily life, though, they share a lot of surface-level symptoms:
- Trouble concentrating
- Restlessness or feeling "on edge"
- Difficulty sleeping
- Irritability
- Procrastination and avoidance
- Feeling overwhelmed by everyday tasks
So two people can describe almost identical struggles while having quite different underlying causes.
The key question: what's pulling your attention away?
One of the most useful distinctions clinicians often look at is the source of distraction.
- With ADHD, attention tends to drift towards whatever is most interesting, new or stimulating in the moment — a sound, a thought, a browser tab. Your mind wanders even when you feel calm.
- With anxiety, attention tends to be pulled towards worry. You can't focus on the report because your mind keeps circling back to what might go wrong.
A simple way to put it: ADHD distraction is often scattered, while anxious distraction is often stuck.
ADHD vs anxiety: side-by-side comparison
| ADHD | Anxiety | |
|---|---|---|
| When it started | Symptoms present before age 12, even if unnoticed | Can begin at any age, often linked to stress or life events |
| Focus problems | Mind wanders to whatever is interesting; hard to sustain attention on dull tasks | Mind is preoccupied with worries and "what ifs" |
| Restlessness | Feels like a need for stimulation or movement | Feels like tension, nervousness or dread |
| Procrastination | Hard to start boring or unstructured tasks | Avoiding tasks because of fear of failure or judgement |
| Sleep | Mind racing with ideas; trouble winding down | Mind racing with worries; trouble switching off fear |
| When calm | Symptoms usually persist even on relaxed days | Symptoms often ease when stress drops |
| Pattern over time | Long-standing and consistent across settings | Can fluctuate with circumstances |
These are general tendencies, not hard rules. Many people recognise themselves in both columns.
When it's both: ADHD and anxiety often co-occur
ADHD and anxiety frequently show up together. Clinicians often see adults whose anxiety grew partly because of unrecognised ADHD.
Think about what years of missed deadlines, forgotten appointments and "why can't you just focus?" comments can do. It's understandable to become a chronic worrier when you never quite trust your own brain to keep up. Some people develop anxious habits — triple-checking, over-preparing, perfectionism — as a way to compensate for ADHD symptoms.
The reverse can also happen: high anxiety can make attention and memory worse, making someone appear more ADHD-like than they are.
Signs that both might be part of your picture:
- You've had focus and organisation difficulties since childhood, and you worry a lot now
- Your worries often centre on forgetting, being late, or letting people down
- Reducing stress helps somewhat, but core attention problems remain
- You use anxiety as fuel to get things done at the last minute
Questions to ask yourself
These questions won't give you an answer, but they can help you notice patterns worth sharing with a professional.
- Can I trace this back to childhood? ADHD symptoms must be present before age 12. Anxiety can start later.
- Does my focus improve when I feel relaxed? If yes, anxiety may be a bigger factor. If calm days still feel scattered, ADHD may be worth exploring.
- What am I thinking about when I lose focus? Random new ideas suggest one pattern; recurring worries suggest another.
- Why do I avoid tasks? Boredom and difficulty starting point one way; fear of the outcome points another.
- Do these difficulties show up everywhere? ADHD typically affects more than one setting, such as work, home and relationships.

Why getting it right matters
Telling ADHD and anxiety apart isn't just a labelling exercise. The two can call for different approaches, and treating only one when both are present may leave you feeling stuck.
For example, someone with unrecognised ADHD might work hard on managing worry, yet still struggle with time management and follow-through. Someone with anxiety might be given focus strategies when what they need is support with the worry itself.
Treatment options for ADHD include medication, therapy or coaching, and skills-based strategies. Anxiety also has well-established, effective treatments. A clinician can help work out what's going on and which combination fits you.
The bottom line
ADHD and anxiety share symptoms like poor focus, restlessness and sleep problems, but they often have different roots. ADHD is long-standing and tends to make attention scattered even when you're calm; anxiety tends to pull attention towards worry and often fluctuates with stress. Very often, they come as a pair.

FAQ
Can ADHD be mistaken for anxiety?
Yes. Because they share symptoms such as restlessness and difficulty concentrating, ADHD can be overlooked when anxiety is more visible, and vice versa. A thorough assessment looks at your full history, including childhood.
Can you have ADHD and anxiety at the same time?
Yes, and it's common. ADHD and anxiety frequently co-occur, and living with unrecognised ADHD can contribute to ongoing worry.
How do I get assessed for ADHD if I already have an anxiety diagnosis?
Speak to your GP or the professional who manages your anxiety and explain your attention concerns. Our guide to getting an adult ADHD assessment walks through what the process usually involves.
