Attention deficit hyperactivity disorder (ADHD) is a condition characterized by inattention, hyperactivity and impulsivity. ADHD is most commonly diagnosed in young people. An estimated 8.8% of children aged 4-17 have ADHD. While ADHD is usually diagnosed in childhood, it does not only affect children. An estimated 4.4% of adults aged 18-44 have ADHD.

With treatment, most people with ADHD can be successful in school, work and lead productive lives. Researchers are using new tools such as brain imaging to better understand the condition and to find more effective ways to treat and prevent ADHD.
