Overview of Attention-Deficit/ Hyperactivity Disorder (ADHD)

Attention-Deficit/ Hyperactivity Disorder (ADHD) is a condition where individuals have a much more difficult time than most people to maintain attention and focus on a task while ignoring distractions, and in many cases they tend to be more restless and impulsive than most people. For the complete definition and list of symptoms of this disorder, see here.

By definition, this condition begins in early childhood and affects over 1 in every 20 children and adolescents in most countries of the world [ref]. Approximately half of these individuals will continue to have symptoms of ADHD in adulthood.

The causes of ADHD are thought to include various genetic and environmental factors that together result in the reduced functioning of certain brain areas that are responsible for focusing the mind on tasks and filtering-out background distractions.

Effective treatments exist that can significantly improve the quality of life of people with this condition.
