The cause of attention deficit hyperactivity disorder, which affects roughly 5.4 million kids in the United States alone, remains unknown. But new research into "mirror movements" sheds light on the mysterious neurobehavioral disorder and might even aid in its diagnosis.
Researchers at the Kennedy Krieger Institute in Baltimore studied 50 children between the ages of 8 to 13 who had been diagnosed with ADHD, and 25 who hadn't, as they tapped the fingers of one hand while resting the other in their laps. The ADHD kids showed increased mirror movements, meaning the voluntary finger taps in one hand were involuntarily reflected in the other.
