The purpose

Background: - Attention deficit hyperactivity disorder (ADHD) is one of the most common and inheritable of all neuropsychiatric disorders. It causes problems with attention and impulse control. However, the genetic component of ADHD has not been fully studied, including how genes interact with the environment. Researchers want to study children and adults who have ADHD. They will look at how genetic, brain structure, and environmental factors affect ADHD in children and adults. Objectives: - To study genetic, brain structure, and environmental factors in ADHD in children and adults. Eligibility: - Individuals at least 3 years of age who have ADHD. Design: - Participants will be screened with a physical exam and medical history. - Participants will be interviewed about their ADHD. They will also complete behavior and psychological tests. Parents or guardians will complete the tests along with participants under 18 years of age. - Participants will provide saliva or blood samples. - Participants will also have imaging studies of the brain. - Participants under 25 years of age will return once a year to repeat the tests. Those over 25 years of age will have only the one set of tests. Those who are starting stimulant drugs and who are receiving behavioral treatment for the first time will also have another set of tests 12 weeks after the start of treatment.
