Research indicates that the potential for serious lifelong traumatic brain injury is increased greatly if a subsequent head injury occurs a short time after a concussion, so a quick and inexpensive means of determining mild brain injuries could be a lifesaver for military personnel, workers, children, and sports participants.

If research by the Army and Cleveland Clinic is successful, then diagnosis for brain injury could include an inexpensive blood test. Medical researchers are developing a test that will determine the presence of a protein that is released into the bloodstream after a person suffers a brain injury.

Researchers are currently testing their findings by analyzing the blood of college football, hockey, and soccer players to even diagnose concussions. Current methods of diagnosing brain injury involve the use of a CT scanner. These scans are expensive and may also fail to detect slight bleeding and other signs of a brain injury.

The military has also ordered nearly 50,000 sensor helmets with the ability to measure severity of blows to the head and to detect for possible concussions. The NFL is partnering with the military to place similar sensors in the helmets of professional football players.
