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. These past statistics might not reflect the current situation, but we believe that the prevalence rate nowadays should be much higher than it was in 2016.
