"Attention-deficit/hyperactivity disorder (ADHD or AD/HD) is a neurobehavioral developmental disorder. ADHD is defined as a “persistent pattern of inattention or hyperactivity—impulsivity that is more frequently displayed and more severe than is typically observed in individuals at a comparable level of development.” It is the most commonly diagnosed psychiatric disorder in children. It affects about 3 to 5% of children globally with symptoms starting before seven years of age. ADHD is generally a chronic disorder with 30 to 50% of those individuals diagnosed in childhood continuing to have symptoms into adulthood. As they mature, adolescents and adults with ADHD are likely to develop coping mechanisms to compensate for their impairment."
