Brain Protein Predicts Recovery Time Following Concussion

SCIENCEDAILY

Elevated levels of the brain protein tau following a sport-related concussion are associated with a longer recovery period and delayed return to play for athletes, according to a study published in the January 6, 2017 issue of Neurology®, the medical journal of the American Academy of Neurology. The findings suggest that tau, which can be measured in the blood, may serve as a marker to help physicians determine an athlete’s readiness to return to the game.

Despite the 3.8 million sports-related concussions that occur annually in the United States, there are no objective tools to confirm when an athlete is ready to resume play. Returning to play too early, before the brain has healed, increases an athlete’s risk of long-term physical and cognitive problems, especially if he or she sustains another concussion. Currently, physicians and trainers must make return-to-play decisions based on an athlete’s subjective, self-reported symptoms and their performance on standardized tests of memory and attention.
