Youngest in class get ADHD label - USATODAY.com: Nearly 1 million children may have been misdiagnosed with attention deficit hyperactivity disorder, or ADHD, not because they have real behavior problems, but because they're the youngest kids in their kindergarten class, researchers say.
Kids who are the youngest in their grades are 60% more likely to be diagnosed with ADHD than the oldest children, according to a study out today from Michigan State University, given exclusively to USA TODAY. A second study, by researchers at North Carolina State University and elsewhere, came to similar conclusions. Both are scheduled for publication in the Journal of Health Economics.
