Raised Protein In Blood Predicts Concussion Severity In Athletes


An interesting new study looking deeper into concussion in response to the raised contention for how athletes are treated after a significant head impact. New Penn Medicine research has found that elevated levels of the brain rich protein calpain- cleaved alpha 2- spectrin N- terminal fragment….deep breath… known in short as SNTF, is an indicator of concussion severity.

If shortly after a head injury ones levels of SNTF are significantly raised, the chances of the athlete going on to develop a diffuse axonal injury and long term cognitive dysfunction can be predicted. Robert Siman, PhD, Research Professor of Neurosurgery at Penn explained:

"This blood test may aid neurobiologically-informed decisions on suitability for return to play following a sports-related concussion."

So any player suffering a head injury can expect to receive a jab in the arm for their trouble too, but this should go some way to protecting athletes in the future.
