What it can look like
Everyday examples.
Fidgeting or needing to move during quiet activities
Feeling internally driven even while sitting still
Talking quickly or finding pauses uncomfortable
Context matters
A pattern is not a diagnosis.
In adults and teens, hyperactivity may feel more like internal restlessness than obvious running or climbing.
Clinicians consider persistence, developmental history, impairment, multiple settings, health, sleep, mood, anxiety, substance use, learning, and other possible explanations.
