Many children with attention deficit hyperactivity disorder will go on to become adults with ADHD, and some adults with the disorder are not diagnosed until adulthood. ADHD expert Stephen Faraone, PhD, discusses how the symptoms in children differ from those seen in adults. He also addresses diagnosis and treatment options. Faraone is a distinguished professor of psychiatry and behavioral sciences and a professor of neuroscience and physiology at Upstate. He  recommends the website ADHDinadults.com as a source of information for both health care providers and the general public.
