Blood Test for Concussions.

Currently, 15-30% of concussion sufferers will experience significant, persistent cognitive deficits, such as processing speed, working memory, and the ability to switch or balance multiple thoughts. Unfortunately, doctors have no reliable way to asses if a concussion sufferer may fall into that group. Now, researchers at the University of Pennsylvania and Baylor College believe they have discovered a blood test that can determine if a concussion sufferer will experience long-term neural complications. By testing blood for elevated levels of a specific protein (STNF), medical professionals can accurately identify if recovery issues will arise and what additional treatment measures should be taken.
