attention-deficit/hyperactivity disorder


attention-deficit/hyperactivity disorder
= ADHD; = attention deficit disorder; = hyperkinetic disorder
a mental disorder, usually of children, characterized by a grossly excessive level of activity and a marked impairment of the ability to attend. Learning is impaired as a result, and behaviour is disruptive and may be defiant or aggressive. The disorder is more common in the low-average intelligence group and in patients with epilepsy or brain damage. Treatment usually involves drugs (such as amphetamines and methylphenidate) and behaviour therapy; the family needs advice and practical help. The illness can carry on into adult life, but more commonly improves as the affected children mature.
