Potential concussion biomarkers discovered in circulating blood after brain injury

Concussions are a commonly diagnosed injury in many sports, particularly at college or professional levels. While the diagnosis of a concussion usually depends upon a careful assessment of symptoms, a simple blood test may help to distinguish those who have suffered brain injury from those who have not. Recently, a large study of sports-related concussions in college athletes pointed to a set of proteins that are elevated in circulating blood post-injury (REF), identifying potential biomarkers for rapid, point-of-care identification of a concussion.
