You can’t finish a task, your mind won’t settle, and you lie awake replaying the day. Is that ADHD? Anxiety? Both? It is one of the most common questions adults bring to an evaluation, and a fair one, because the two conditions can look almost identical from the inside. This article explains how a careful adult ADHD evaluation separates them, what else can mimic both, and what happens when the answer is “both.”

If you want the step-by-step logistics of an evaluation, such as forms, number of visits and documentation, see our adult ADHD evaluation page. This article focuses on the hardest part of the process: telling ADHD apart from anxiety and other look-alikes.
Why ADHD and anxiety are easy to confuse
Both can cause trouble concentrating, restlessness, irritability, poor sleep and a sense of always being behind. Both can make you procrastinate. Both get worse under stress. And the two often travel together: many adults with ADHD also meet criteria for an anxiety disorder, sometimes because years of missed deadlines and last-minute scrambles teach the nervous system to stay on alert.
The difference usually lies not in whether attention is affected, but in why and since when.
Five questions that help tell them apart
1. When did it start?
ADHD is a neurodevelopmental condition. Several symptoms need to have been present before about age 12, even if no one called it ADHD at the time. Report cards that say “bright but doesn’t apply himself” or “talks too much in class” are clues. Anxiety can begin at any age, and attention problems that first appear at 35, after a promotion or a new baby, point toward other causes first.
2. What pulls your attention away?
With anxiety, attention is usually hijacked by worry: you read the same email four times because your mind keeps jumping to what might go wrong. With ADHD, attention drifts toward whatever is more interesting, or simply drifts, even when you feel calm. People with ADHD often describe being able to hyperfocus on things they enjoy while struggling with anything boring.
3. Does it improve when you are relaxed?
On vacation, with nothing to worry about, does your focus come back? If yes, anxiety or stress may be the main driver. If you lose your keys, miss turns and forget plans just as often on a calm Saturday, ADHD becomes more likely.
4. Is it in every setting?
ADHD symptoms show up across settings: work, home, relationships and money. Anxiety-related focus problems can be more situational, worse in the settings that trigger worry.
5. What does the restlessness feel like?
Anxious restlessness feels like dread or tension. ADHD restlessness often feels like boredom, an itch to move or an urge to do something else.
No single answer settles the question. A clinician looks at the full pattern.
Other things that can mimic ADHD or anxiety
A thorough evaluation also checks for conditions that cause similar symptoms or make them worse:
- Sleep problems, including insomnia and possible sleep apnea. Poor sleep alone can wreck focus. Sleep studies are arranged by referral.
- Depression, which slows thinking and drains motivation.
- Hormonal change, such as perimenopause, which can bring brain fog and new anxiety. See perimenopause anxiety.
- Medical factors like thyroid problems or anemia, which labs can help rule out when clinically appropriate.
- Substances, including heavy caffeine, alcohol and cannabis.
- Trauma, which can keep the body on high alert and make concentration hard. See PTSD treatment.
What the evaluation looks like
At IPW Health, a psychiatric evaluation with a psychiatric nurse practitioner is a detailed conversation about your childhood, school and work history, relationships, sleep, health and family history. You may complete standardized rating scales for ADHD and anxiety. With your permission, your provider may ask a partner, parent or close friend for their observations, because people who know you well often notice patterns you don’t. Old report cards help too.
Your provider then explains what fits and what doesn’t. Sometimes the answer is ADHD, sometimes anxiety, sometimes both, and sometimes something else entirely, such as a sleep or mood problem. That is still useful: it tells you where to put your energy. Formal neuropsychological testing is not done in house and is arranged by referral when it is needed.
When it’s both
If you have ADHD and anxiety, the plan addresses both, and the order matters. For some people, getting ADHD symptoms under control reduces the constant worry about falling behind. For others, anxiety needs attention first. Your provider will talk through the options and the trade-offs, including how any treatment could affect sleep or anxiety, and will follow up closely. Therapy such as CBT can help with both: organization and planning skills for ADHD, and tools for catching anxious thoughts. Our adult ADHD treatment and anxiety treatment pages explain more.

Frequently asked questions
Can anxiety look exactly like ADHD?
It can look very similar, because both affect focus, sleep and restlessness. The biggest differences are usually when symptoms started and what pulls your attention away: worry with anxiety, or drifting and boredom with ADHD.
Can you have ADHD and anxiety at the same time?
Yes. The two often occur together in adults. An evaluation can identify both, and the treatment plan addresses each.
Do I need childhood records for an adult ADHD evaluation?
They are not required, but they help. Old report cards, teacher comments or input from a parent can show whether symptoms were present before about age 12.
What if my evaluation shows anxiety, not ADHD?
That is still a useful answer. Your provider will explain the findings and recommend next steps, which may include therapy, treatment for anxiety, and attention to sleep or other factors.
