Attention Deficit Hyperactivity Disorder: What Is ADHD?

Attention-deficit/hyperactivity disorder (ADHD) is also known as hyperactivity or attention deficit disorder (ADD). ADHD is a common condition that affects both children and adults.

The National Institute of Mental Health (NIMH) estimates that 3% to 5% of children have ADHD. Some experts, though, says ADHD may occurs in 8% to 10% of school age children. Experts also question whether kids really outgrow ADHD. What that means is that this disorder may be more common in adults than previously thought.

Children with ADHD generally have problems paying attention or concentrating. They can't seem to follow directions and are easily bored or frustrated with tasks. They also tend to move constantly and are impulsive, not stopping to think before they act. These behaviors are generally common in children. But they occur more often than usual and are more severe in a child with ADHD.

The behaviors that are common with ADHD interfere with a child's ability to function at school and at home.

Adults with ADHD may have difficulty with time management, organizational skills, goal setting, and employment. They may also have problems with relationships, self-esteem, and addictions.
