Of Little Brain: Research suggests that hyperactive kids might have smaller than normal brains. It was a small study - only 152 kids were measured; and the differences in size were small - only 3 to 4%. There are definitely kids with ADD who have something wrong with their wiring. The problem is that a lot of kids get labeled with that diagnosis who aren’t really ADD. It would be nice to have an objective way to diagnosis the disorder, but I don’t think we’ll be measuring kids brains to do it anytime soon:

``The first thought people have is that this is a product of bad parenting'' or that it is environmental, said Dr. Daniel Coury, a professor of clinical pediatrics at the Ohio State University College of Medicine, who was not involved in the research. ``Having clear biological findings that this is something beyond the control of parents or the child themselves helps to remove that stigma.''

Is it any less stigmatizing to be told you're a child of very little brain?
