If you rely on energy drinks to rev you up, this may change your mind: Teens who down the heavily caffeinated drinks may be more prone to traumatic brain injury (TBI), according to a new University of Toronto study.
Although TBIs happen in a variety of ways ? falls, fistfights, car accidents ? the No. 1 cause among teens is sports. And, unfortunately, the rate of brain damage is only rising: Between 2001 and 2009, the number of sports-related head injuries among children (ages 19 or younger) leapt by 57 percent, according to a CDC analysis.
