ADHD (Attention Deficit Hyperactivity Disorder) Symptoms & Signs

Medical Author:

While inattention and hyperactivity are the cardinal symptoms of ADHD, a number of other symptoms are contained within the diagnostic criteria for this condition and are typical for those with ADHD.

Symptoms related to inattention include trouble paying attention in school or work, the appearance of not listening, failing to complete assigned tasks, avoidance of activities that require sustained focus, losing things, and being easily distracted. Symptoms related to hyperactivity include restlessness, fidgeting, interrupting, frequent talking, intrusiveness, trouble paying attention, and trying to do multiple things at once.

Children and adults with ADHD may also have symptoms like insomnia, low tolerance for frustration, poor self-image, forgetfulness, disorganization, mood swings, and "hyperfocus," a tendency to intensely focus on one task or event that precludes focus on other necessary tasks.
