Attention Deficit Hyperactivity Disorder (ADHD) and Attention Deficit Disorder (ADD) are terms often used interchangeably. Although similar, ADD is actually a subset of ADHD.
The primary difference in the disorders is that ADD manifests primarily as inattention, distractability, lack of organization, and inability to concentrate. ADHD includes excessive talking, fidgeting, restlessness, interrupting others, and being constantly in motion. A child can have a combination of these symptoms and the diagnosis is based on the number and severity of symptoms that are observed in home and in school.
ADHD is the most commonly diagnosed childhood neurological disorder with an estimated 1 in 20 children in the United States affected. ADHD is not just a childhood disorder. It affects adults as well.
