In recent years, we’ve seen a growing number of sportspeople speak out about their experiences of head injuries, and concussions are forcing more and more athletes to take a break from or cut short their sporting careers.  And research on the brains of former athletes is raising awareness of the long-term neurological damage that can be caused by repeated, apparently minor knocks to the head.  Associate Professor  Fatima Nasrallah is currently spearheading a ground-breaking study here at the Queensland Brain Institute, investigating the long-term effects of concussion on the brain.
