Neurologists at Mayo Clinic in Arizona have used autonomic reflex testing to find physical signs a concussion has occurred, a step toward creating a diagnostic test to gauge the severity of concussions.
In the study of 21 patients, each patient displayed the same abnormality, viewed as a sign a concussion has occurred. The hope is that, with more testing, what happens with this abnormality over time will prove a reliable physical sign of recovery.
Right now, physicians rely on a patient reporting when symptoms have subsided to determine stages of recovery. Doctors know from functional imaging studies that there is a lag between when the person reports that their symptoms have resolved and the time they are actually healed.
Above, David Dodick, M.D., Brent Goodman, M.D., and Bert Vargas, M.D., neurologists at Mayo Clinic in Arizona, discuss their study findings presented today at the 2013 American Academy of Neurology Annual Meeting.
