Attention Deficit Hyperactivity Disorder

Attention deficit hyperactivity disorder (ADHD) is a problem with paying attention and focusing on tasks. People who have ADHD tend to act without thinking and have trouble sitting still.

ADHD may begin in early childhood and can continue into adulthood. Without treatment, it can cause problems at home, at school, at work, and with relationships.
