DESCRIPTION
A pattern of behaviour in children characterized by short attention spans and impulsivity, with or without hyperactivity, attention deficit disorder (ADD) is implicated in learning disorders and estimated to affect 5–10% of school-aged children with incidence substantially greater in boys than girls (10 : 1). Over two million American school-aged boys take the drug methyl-phenidate (Ritalin) for ADD. Onset is usually by 3 years of age, but diagnosis is generally not made until later when the child is in school.
