Narrator:       This is Science Today. For the first time, researchers found direct evidence of a disconnect between two brain regions in children with attention deficit hyperactivity disorder, or ADHD. Blythe Corbett, a researcher at the University of California, Davis' M.I.N.D. institute participated in this study and says there's still a belief among some people that ADHD is solely a behavior-based disorder, or that it's the fault of parents not regulating their child's behavior.

Corbett:          We clearly have, in addition to other neuroscientists, a finding here that supports that their brains are functioning very differently and so probably one of the over-arching goals and hopes that I have as a clinical scientist is that people take this more seriously and they recognize that a child does want to sit in the chair and pay attention in class. This is a serious condition. There is functional disconnection, it looks like, in certain parts of the brain, but we believe that we can address it through providing behavioral supports.
