 Severity of ADHD may be Assessed by Hand Movements
Hand-movement control can be used as a parameter to assess the severity of attention-deficit hyperactivity disorder (ADHD), says a new research by scientists from Cincinnati Children's Hospital Medical Center and the Kennedy Krieger Institute in Baltimore.

Researchers noted that kids with ADHD had extra movements. Using sequential finger-tapping experiments on youngsters, the researchers observed that these "overflow" movements were twice the amount as seen in normal youngsters.

The study involved 50 right-handed children ages 8 to 13. Half of them had ADHD, while the other half did not. The finger-tapping movements of these kids were recorded with a video and electronic finger positioning device that measured "excessive mirror overflow." It was found that boys with ADHD had nearly 4 times the excess overflow as compared with normal boys. This variation was not seen in girls.

"We now have a real, quantifiable measure of a problem with controlling behavior in these children," said Dr. Stewart Mostofsky, senior author of the finger-tapping study.

The study appears in the February 15 print issue of the journal Neurology.
