Answer:
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, or excessive activity and impulsivity, which are otherwise not appropriate for a person's age.[1][2][11][12] Some individuals with ADHD also display difficulty regulating emotions or problems with executive function.[13][14][15][2] For a diagnosis, the symptoms should appear before a person is twelve years old, be present for more than six months, and cause problems in at least two settings (such as school, home, or recreational activities).[3][16] In children, problems paying attention may result in poor school performance.[1] Additionally, there is an association with other mental disorders and substance misuse.[17] Although it causes impairment, particularly in modern society, many people with ADHD can have sustained attention for tasks they find interesting or rewarding (known as hyperfocus).
