Attention-Deficit/Hyperactivity Disorder (ADHD)

The Attention Deficit Hyperactivity Disorder (ADHD) topic includes research on the causes, diagnosis, prevention, and treatment of ADHD, a disorder marked by an ongoing pattern of inattention, hyperactivity, and/or impulsivity.

ADHD is one of the most common childhood disorders and can continue through adolescence and into adulthood. Symptoms include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (over-activity).

ADHD often co-occurs with other disorders and conditions, such as disruptive behavior, learning disorders, sleep problems, anxiety, or depression, which can make the conditions harder to diagnose and treat. The exact cause of ADHD is unknown but likely results from a combination of factors, such as genetics and the environment.
