Do high-impact sports damage our brains?

Whether it’s watching your kids play their local club fixtures or gathering around the telly for the grand final, sport brings Australians together more than almost anything else. But there’s a hidden – and potentially deadly – cost.  Lydia loves Aussie Rules football, but she was forced to retire from the sport before turning 30. After a series of head knocks, the risk of another is too high, and managing the symptoms of her injuries is a daily struggle. Associate Professor Michael Buckland studies the brain, and through the Australian Sports Brain Bank, he examines the brains of athletes who’ve passed away. He’s worried by just how many brains come into the bank and are revealed to have CTE, or chronic traumatic encephalopathy.   It’s a degenerative brain disease caused by repeated head impacts over a long period of time. In other words, the kind of thing that might happen if you’ve been playing collision sports since you were a kid.   Michael explains how our understanding of CTE has changed in recent years, its causes, and most importantly, how we can mitigate the risk of CTE for all athletes, of all ages.   NOTE: This episode contains a reference to suicide.
