Blood test offers swifter, safer diagnosis of sport brain injury

LONDON (REUTERS) - Swedish researchers say they have devised a blood test that could better diagnose sports-related brain injuries and prevent American football, rugby and ice hockey players returning to the field in danger.

"In ice hockey and other contact sports, repeated concussions are common, where the brain has not finished healing after the first blow," said Professor Henrik Zetterberg of the Sahlgrenska Academy at the University of Gothenburg, who led the study.
