attention deficit disorder

Attention deficit disorder (ADD), is the old name for a disorder in which a person shows a certain pattern of behavior over time. This pattern includes inattention and impulsivity. Attention deficit / hyperactivity disorder, (AD/HD) as it is now called, is characterized by physical hyperactivity, impulsivity, and/or distractibility, in addition to the other behaviors.
