With growing evidence about concussion, repetitive head impacts and long-term brain disease, have we underestimated the risks of sport all along? How did we get here, what do we really know about head injuries and given the risks, is it time to rethink children’s participation in sport?

In this episode, we chat to Alan Pearce, a neuroscientist and Adjunct Professor at Swinburne University of Technology in Melbourne who has been researching sports-related concussions for more than two decades.
