Attention Deficit Hyperactivity Disorder: Symptoms of ADHD

The symptoms of ADHD include inattention and/or hyperactivity and impulsivity. These are traits that most children display at some point or another. But to establish a diagnosis of ADHD, sometimes referred to as ADD, the symptoms should be inappropriate for the child's age.

ADHD is common in children and teens. Adults also can have ADHD. With ADHD in adults, there may be some variation in symptoms. For instance, an adult may experience restlessness instead of hyperactivity. In addition, adults with ADHD consistently have problems with interpersonal relationships and employment.
