Pediatric attention deficit hyperactivity disorder (ADHD) is a controversial diagnosis and everybody has an opinion on medications like Ritalin. Dr. Rick Mayes, associate professor of public policy at the University of Richmond's department of political science and a faculty research fellow at the Petris Center on Healthcare Markets and Consumer Welfare at University of California, Berkeley, reminds us that this ongoing dialogue doesn't really reflect the scientific validity of ADHD and its treatment, but rather gives us a window into what happens when science is translated into public policy, rules and even the law. Dr. Leslie Lundt hosts.
