Attention Deficit Hyperactivity Disorder



Attention-deficit hyperactivity disorder (ADHD) is a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with completing daily activities or development. Many children and adults are affected by ADHD. People with a diagnosis of ADHD may have trouble at home, school, work, or socially.
 
Children with ADHD 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. ADHD is more common in boys than in girls.
