"Both the ears and fingers of children diagnosed with one type of attention-deficit/hyperactivity disorder (ADHD) differ from those of children diagnosed with another type of ADHD, according to researchers at The University of Texas at Austin."

“We believe that these findings support a contention that many of us have been making for years,” said Dr. Caryn Carlson, another member of the research team. “The current categories of ADHD/Inattentive and ADHD/Combined may constitute different disorders, not different subtypes of a single disorder.”
