Anxiety and ADHD can look surprisingly alike: both can cause restlessness, trouble concentrating, poor sleep and feeling overwhelmed. They also often occur together. Telling them apart matters, because the treatments differ. This guide explains the key differences, the overlap, and how to get a proper evaluation. Only a qualified clinician can diagnose either.

Key differences
| Anxiety | ADHD | |
|---|---|---|
| Why focus slips | Worry and “what if” thoughts take over attention | Attention drifts regardless of mood; trouble sustaining focus on boring tasks |
| Restlessness | Driven by tension or dread | Long-standing need to move; impulsivity |
| Onset | Can start at any age, often linked to stressors | Symptoms present since childhood (before 12) |
| Consistency | Worse in stressful situations | Present across settings most of the time |
| Procrastination | Avoiding because of fear of failure | Difficulty starting or organizing tasks |
Why they’re often confused
- Both cause trouble concentrating and sleeping.
- Living with untreated ADHD (missed deadlines, forgotten tasks) can create real anxiety.
- Anxiety can mimic inattention, especially in adults.
- Each can make the other worse.
Can you have both?
Yes. A significant share of adults with ADHD also have an anxiety disorder. When both are present, clinicians usually treat both, sometimes deciding which to address first based on what’s most disruptive.

Getting evaluated
An ADHD assessment usually involves a detailed history (including childhood), rating scales and sometimes input from family. Anxiety is assessed with interviews and questionnaires such as the GAD-7. A psychologist or psychiatrist can assess both.
Treatment differences
- Anxiety: CBT and exposure-based therapy are first-line; medication is an option to discuss with a doctor.
- ADHD: often a combination of medication (prescribed and monitored by a doctor) and skills-based therapy, coaching and environmental changes.
- Both: CBT adapted for adult ADHD can help with organization and the anxiety that comes with it.
Note: Online-Therapy.com provides therapy, not ADHD medication or diagnostic testing. If you suspect ADHD, ask your doctor or a psychiatrist for an evaluation; therapy can still help with anxiety, stress and coping skills.
