FDA: Concussion & blood Test To Assist With Concussion Evaluations

Just over 1-year ago, FDA authorized first blood test to aid in the evaluation of concussion in adults. 

Today, Research: Concussion & Blood Biomarker for Predicting Concussion Recovery

Now, a small study published online in Neurology showed blood-based inflammation biomarker predicted  concussion symptom recovery time.

The study involved 43 high school and college football players who had concussions. Author of study, Timothy B. Meier, PhD,  a member of the American Academy of Neurology, states:

“With so many people sustaining concussions and a sizeable number of them having prolonged symptoms and recovery, any tools we can develop to help determine who would be at greater risk of problems would be very beneficial, so these results are a crucial first step.”

However, Michael Alosco, PhD, of Boston University, who was not involved with the study, told MedPage Today :

“These inflammatory markers actually might be very important for identifying who does go on to have prolonged problems or delayed recovery…. What you really need is a panel of biomarkers that can start to tease apart different causes.”
