Blood test identifies brain damage from concussion in ice hockey
News   Mar 14, 2014

Half way into last year's season, 35 of 288 players in the Swedish Hockey League had already had a concussion. Researchers at Sahlgrenska Academy, who surveyed all of the players in the league's 12 clubs, have now developed a method that can show just an hour after the injury how severe the concussion is, if there is a risk of long-term symptoms and about when the player can return to the game.
