Narrator: This is Science Today. Recent findings that there is a disconnect between certain brain regions in children with attention deficit hyperactivity disorder, or ADHD, may result in earlier clinical diagnosis. Dr. Ron Mangun, a professor of psychology and neurology at the Center for Mind and Brain at the University of California, Davis says this new insight may serve as a biological marker for whether a child has the disorder or not.
Mangun: Not all the children with the disorder display the same sets of behaviors and perhaps this will turn out as we go forward and do future research, that this biomarker of ours in the brain waves, correlates with one subtype of the disorder and not others.
Narrator: Mangun says they may even find that there's another diagnostic category all together.
Mangun: And that's the hope for a lot of the disorders; not just ADHD, but for a lot of disorders, whether it be schizophrenia or other very, very complicated disorders where the pattern of behaviors moves across a wide range. And we're pretty sure that there may be different underlying aspects to the disorder.
