Adult ADHD Self-Test: Do I Have ADHD?
Many adults discover ADHD late – often after their child's diagnosis or because work has stopped working. This article shows the signs and what a serious self-test looks like.
Three symptom types
ADHD is more than being "fidgety":
- Inattentive: focus issues, forgetfulness, procrastination, distractibility.
- Hyperactive-impulsive: inner restlessness, talking without filter, impatience, impulsive decisions.
- Combined: both at once.
In adults, the hyperactivity is often internal – outwardly calm, head spinning.
Everyday signs
- You start ten tasks and finish none.
- Keys, phone, appointments – constantly lost.
- You need pressure (deadlines, adrenaline) to get going.
- Emotions are intense and fast, hard to regulate.
- Frequent job, hobby or relationship changes.
ADHD or autism – or both?
The two spectrums overlap. Both can cause sensory overload, but the mechanics differ:
- ADHD: too many stimuli at once, no filter.
- Autism: single stimuli become unbearably intense.
- AuDHD: both – amplifying each other. See AuDHD in adults.

The ADHD Check is based on the WHO ASRS scale and takes about 5 minutes. You get an assessment, not a diagnosis.
What to do if you suspect ADHD
- Note concrete examples from childhood, school, work.
- Talk to your GP or a specialist clinic directly.

Driving fitness
Untreated ADHD measurably increases crash risk; treated ADHD brings it back down. If unsure, consult a traffic-medicine specialist.
