There is a potential new test for brain injuries currently in development. Researchers are closing in on identifying biomarkers that would allow diagnosis of brain injuries with a simple blood test. The biomarkers are proteins produced by an injured brain. Such testing could allow for quicker diagnosis of a brain injury and quicker appropriate medical treatment. For example, brain injury is not just an immediate injury. It is a disease process that can last for days following the traumatic event. During that time, a cascade of biomarker proteins are produced. This suggests that the brain damage continues to take place. If a simple blood test could result in an immediate diagnose, earlier medical intervention could prevent the additional brain damage from occurring.
