But the science of sports-related head injuries, including how to measure recovery and decide when it's OK for a patient to play again, needs work.

This study proposes using blood biomarkers to diagnose sports-related concussions. To study the phenomenon, researchers used 280 players from 12 teams in the Swedish Hockey League, the top professional ice hockey league in Sweden.
