Attention-deficit hyperactivity disorder (ADHD) is the name of a group of behaviors found in many children and adults. People who have ADHD have trouble paying attention in school, at home or at work. Even when they try to concentrate, they find it hard to pay attention. Children may be much more active and/or impulsive than what is usual for their age. These behaviors contribute to significant problems in relationships, learning and behavior. For this reason, children who have ADHD are sometimes seen as being “difficult” or as having behavior problems.
People who have ADHD have a hard time organizing things, listening to instructions, remembering details and controlling their behavior. As a result, people who have ADHD often have problems getting along with other people at home, at school or at work.
Often adults who have ADHD are diagnosed when they find out their children have ADHD. This health problem may run in families. Reasearch shows that ADHD is more common in people who have close relatives with the disorder. Other medical problems may also mimic ADHD symptoms.
