ADD and ADHD are not diseases or mental retardation. People with ADHD are usually physically healthy and are often very smart and creative.

There are three patterns of behavior - hyperactivity, inattentiveness and impulsivity. A child may exhibit some or all of these behaviors.

No single cause has been found, although researchers have found chemical, size, and function differences in the brains of children with ADD and ADHD. Many have a close relative with the disorder.

While there are many different treatments available, including medication and behavioral therapy, there is no cure.
