Neurologists at Mayo Clinic in Arizona have taken a promising step toward identifying a test that helps support the diagnosis of concussion. Research has shown that autonomic reflex testing, which measures involuntary changes in heart rate and blood pressure, consistently appear to demonstrate significant changes in those with concussion. In the study, Mayo Clinic doctors monitored 21 consecutive patients after concussion, and all experienced significant abnormalities in heart rate and blood pressure during autonomic testing. The physicians conclude that these abnormalities are tied to the concussion.
