Attention deficit hyperactivity disorder (ADHD) is a common childhood psychiatric disorder with a prevalence of 4 to 8%. ADHD is characterized by hyperactivity, impulsiveness, and inappropriate inattentiveness. Though long considered a disease of childhood, studies have shown that a majority of cases persist in adulthood causing significant psychosocial impairment. Diagnosis is often based on clinical symptoms, and psychostimulants are mainstay in treatment of ADHD that are often complemented by psychotherapy and behavioural modifications.
