Impulsive Behavior: What to Know

Medically Reviewed By Yalda Safai, MD, MPH

Impulsivity is a tendency to take action without thinking. A small amount of impulsive behavior can be typical, especially for children. However, extensive or frequent impulsive behavior may suggest an underlying health condition, such as ADHD or a concussion. Impulsive behavior itself is not a condition or diagnosis. Instead, it may be a symptom or sign of an underlying condition.

Still, it is standard for everyone to experience a small amount of impulsivity occasionally. This may be particularly true for children and adolescents, whose brains are still developing.

If impulsive behavior is very frequent or is starting to have negative effects on life, however, it may be helpful to talk with a doctor. They can identify whether any underlying conditions may be contributing to impulsivity and help you access treatment if necessary.

This article explains impulsive behavior examples, symptoms, and underlying causes. It also discusses treatment options and some frequently asked questions about impulsive behavior.
