Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder of the neurodevelopmental type. It’s characterized by problems paying attention, excessive activity, or difficulty controlling behavior which is not appropriate for a person’s age.These symptoms begin by age six to twelve, are present for more than six months, and cause problems in at least two settings (such as school, home, or recreational activities).In children, problems paying attention may result in poor school performance.Although it causes impairment, particularly in modern society, many children have a good attention span for tasks they find interesting.

 

Despite being the most commonly studied and diagnosed psychiatric disorder in children and adolescents, the cause is unknown in the majority of cases. The World Health Organization estimated that it affected about 39 million people as of 2013. It affects about 5–7% of children when diagnosed via the DSM-IV criteria and 1–2% when diagnosed via the ICD-10 criteria.Rates are similar between countries and depend mostly on how it is diagnosed. ADHD is diagnosed approximately three times more in boys than in girls. About 30–50% of people diagnosed in childhood continue to have symptoms into adulthood and between 2–5% of adults have the condition. The condition can be difficult to tell apart from other disorders as well as to distinguish from high levels of activity that are still within the normal-range.

ADHD management recommendations vary by country and usually involve some combination of counseling, lifestyle changes, and medications. The British guideline only recommends medications as a first-line treatment in children who have severe symptoms and for the medication to be considered in those with moderate symptoms who either refuse or fail to improve with counseling.Canadian and American guidelines recommend that medications and behavioral therapy be used together as a first-line therapy, except in preschool-aged children.Stimulant therapy is not recommended as a first-line therapy in preschool-aged children in either guideline. Treatment with stimulants is effective for up to 14 months; however, its long term effectiveness is unclear. Adolescents and adults tend to develop coping skills which make up for some or all of their impairments.

The medical literature has described symptoms similar to ADHD since the 19th century. ADHD, its diagnosis, and its treatment have been considered controversial since the 1970s.The controversies have involved clinicians, teachers, policymakers, parents, and the media. Topics include ADHD’s causes and the use of stimulant medications in its treatment. Most health care providers accept ADHD as a genuine disorder, and the debate in the scientific community, mainly centers on how it is diagnosed and treated. The condition was officially known as attention deficit disorder (ADD) from 1980 to 1987 while before this it was known as hyperkinetic reaction of childhood.
