ADHD is an abbreviation for attention deficit hyperactivity disorder. It is a common medical condition characterized by hyperactivity, impulsivity, and inattention.
ADHD affects not only children but also adults. According to the 2016 National Survey of Children’s Health (NSCH), the proportions of children and adults having ADHD were 8.4% and 2.5%, respectively.
