December 17, 2013 A chronic brain disease afflicts former pro football players, boxers and others who suffer repeated brain injuries. Doctors now can only diagnose it with certainty after someone dies. But researchers are working on tests that could work while people are alive.
December 11, 2013 Student athletes know they need to avoid concussions. But hits that don't cause concussion symptoms can affect the brain, too. Researchers are now trying to figure out who is most at risk from those smaller hits, and if they can be warned in advance.

February 3, 2012 High school football players experienced brain changes long before they had symptoms of concussion. The findings suggest that concussions come from cumulative damage, researchers say.
February 2, 2012 Computerized testing of athletes for concussion isn't a reliable gauge of their brain health or fitness to return to play, according to new research. The computerized tests are used in the NFL and NHL, and in many colleges and high schools.
