ADHD Hyperactivity-Impulsivity Symptoms

Understanding hyperactive and impulsive behaviors in ADHD

Hyperactivity-impulsivity is one of the two main symptom categories in ADHD. These symptoms involve excessive physical movement, restlessness, and difficulty with impulse control.

Hyperactivity Symptoms

• Fidgeting or tapping hands/feet frequently
• Difficulty remaining seated in situations where it's expected
• Running or climbing at inappropriate times (restlessness in adults)
• Unable to play or engage in activities quietly
• Often "on the go" as if "driven by a motor"
• Excessive talking

Impulsivity Symptoms

• Blurting out answers before questions are completed
• Difficulty waiting turn in conversations or activities
• Often interrupting or intruding on others
• Making hasty decisions without considering consequences
• Acting or speaking without thinking

Age-Related Changes

Hyperactivity-impulsivity symptoms often change with age:

• Children may show more obvious physical hyperactivity
• Teens might experience more internal restlessness
• Adults often report feeling driven by an "internal motor"
• Impulsivity may shift from physical actions to decision-making
