Document Summary
Attention deficit disorder (add) is a variation in central nervous system processing characterized by developmentally inappropriate behaviors involving inattention. When hyperactivity and impulsivity accompany inattention, the disorder is called attention deficit hyperactivity disorder (adhd). The latter is the most common mental health alteration of childhood, affecting about 8. 4% of all school- age children. Boys are affected almost four times more commonly than girls. It is now known to affect adolescents and adults; those with the disorder often continue to manifest at least some of the symptoms as they grow into adulthood. Hyperactivity and impulsivity may improve as the child nears adulthood, with inattentiveness the most persistent characteristic. The adolescent may have difficulty due to the increasing cognitive demands of school. Examples of known associations include exposure to high levels of lead or mercury in childhood and prenatal exposure to alcohol or tobacco smoke.
