Hyperkinetic disorder is the generic ICD-10 (WHO, 1992) term used to describe one of the most common childhood psychiatric disorders. It is a severe form of a syndrome which is referred to in DSM–IV (APA, 1994) and the American literature as attention deficit hyperactivity disorder (ADHD). Hyperactivity or hyperkinesis can be defined as “an enduring disposition to behave in a restless, inattentive, distractible and disorganised fashion” (Taylor, 1994). It is thus more than motor overactivity. Diagnostically there are three main groups of symptomatology: overactivity, inattentiveness and impulsiveness.
