Condition Basics
What is attention deficit hyperactivity disorder (ADHD)?
Attention deficit hyperactivity disorder (ADHD) is a common condition. A person who has ADHD has trouble paying attention and focusing on tasks, tends to act without thinking, and has trouble sitting still.
It may begin in early childhood and can continue into adulthood. ADHD can be treated with medicines, behavior therapy, and counseling. Treatment can improve your life.
In the past, ADHD was called attention deficit disorder (ADD).
What causes it?
The exact cause of ADHD is not clear, but it tends to run in families. Ongoing research is focused on finding the genes that may make a person more likely to get ADHD. Although many parents believe that foods with sugar and food additives make their children more hyperactive, these foods haven't been shown to cause ADHD.footnote 1
