The first reliable description of ADHD comes from England in early 20 th century. The prevalence of this disorder varies from 1% to 20% depending on the diagnostic criteria, the population of children studied and the source of information. Around 60% of ADHD children will carry some of their behavior in adulthood. 1 The cardinal symptoms are inappropriate levels of inattentiveness, motor over-activity and impulsivity. The symptoms must appear in at least two contexts, for duration of atleast 6 months, have an onset before age of 7 years and cause significant functional impairment. 2 Recent reports highlight behavioral, social, familial and academic difficulties in school age children with ADHD as compared to their counterparts without ADHD. 3
