19 Jan 2020
People with ADHD also have problems with hyperactivity and impulsivity.
Hyperactivity is simply having a high level of activity or excitement.
Impulsivity is defined as acting suddenly on an idea or emotion, without first thinking it through.
In order to diagnose hyperactivity, a person must have had 6 of the following symptoms (5 for individuals older than 17 years):

1. Often fidgets with or taps hands or feet or squirms in seat;

2. Often leaves seat in situations when remaining seated is expected;

3. Often runs about or climbs in situations where it is not appropriate (adolescents or adults may be limited to feeling restless);

4. Often unable to play or take part in leisure activities quietly;

5. Is often "on the go," acting as if "driven by a motor";

6. Often talks excessively;

7. Often blurts out an answer before a question has been completed;

8. Often has trouble waiting for his or her turn;

9. Often interrupts or intrudes on others (e.g., butts into conversations or games).

A diagnosis is based on the symptoms that have occurred over the past 6 months.
