The scientific controversy over head injuries in sport

At a Senate committee last year, the NRL and Football Australia acknowledged the link between head injuries in contact sports and the neurodegenerative disease chronic traumatic encephalopathy (CTE).But a core member of the NRL’s concussion research group is also one of the most outspoken critics of the link between repeated head injury and CTE, calling it an “invented disease … conjured out of thin air”.His views corroborate the Australian NRL’s multimillion-dollar research program into former elite-level rugby league players, which to date has concluded there is no link between concussion and depression or other cognitive problems.So how does the NRL justify advancing a position that most scientists don’t agree with? Today, journalist and contributor to The Saturday Paper Wendy Carlisle, on the brain epidemic killing ex-athletes and why the science is still being contested.Socials: Stay in touch with us on Twitter and InstagramGuest: Journalist and contributor to The Saturday Paper, Wendy Carlisle.See omnystudio.com/listener for privacy information.
