Autonomic Dysfunction and Concussion - Mayo Clinic

David Dodick, M.D., Brent Goodman, M.D., and Bert Vargas, M.D., neurologists at Mayo Clinic in Arizona, discuss study findings presented at the 2013 American Academy of Neurology Annual Meeting. Currently, there is no biomarker or diagnostic test to both reliably indicate when a brain concussion has occurred and when the brain has recovered. The study results indicate that autonomic nervous dysfunction is common in concussion and autonomic nervous system testing may be a sensitive biomarker in patients with concussion.
