Hyperactive ADHD Symptoms
Direct answer
What are the hyperactive symptoms of ADHD?
Hyperactivity in ADHD means persistent, excessive motor activity or restlessness that is inappropriate to the situation — such as fidgeting, leaving one's seat, running or climbing in children, talking excessively and difficulty relaxing. In adults it often becomes an inner sense of restlessness rather than visible over-activity.
- Fidgeting, restlessness and difficulty staying seated
- Excessive talking
- Feeling 'driven by a motor'
- In adults, often inner restlessness
- Must be beyond normal for age and impairing
Hyperactivity symptoms
- Often fidgets, taps hands or feet or squirms in seat
- Often leaves seat when remaining seated is expected
- Often runs or climbs where inappropriate (in adults, feeling restless)
- Often unable to play or take part in leisure activities quietly
- Is often 'on the go', as if driven by a motor
- Often talks excessively
How hyperactivity changes with age
Visible hyperactivity often reduces through adolescence. Adults may instead describe being unable to sit through films or meetings, choosing active jobs, feeling uncomfortable when still, or a constant mental restlessness.
Other explanations clinicians consider
Anxiety, agitation in low mood, hypomania, thyroid over-activity, stimulant use and sleep disorders can all cause restlessness. A developmental history showing a lifelong pattern helps distinguish ADHD.
