The hockey world is mourning the sudden death of former Montreal Canadien Claude Lemieux, as experts say his family’s decision to donate his brain to research could help advance understanding of a devastating disease.
Lemieux died by suicide in Florida last week, just days after appearing in Montreal, where he carried a ceremonial torch into the Bell Centre for Game 3 of the Eastern Conference final against the Carolina Hurricanes.
His family has since chosen to donate his brain to Boston University’s CTE Center, contributing to ongoing research into the long-term effects of repeated head injuries.
“I was very appreciative that the Lemieux family chose to donate his brain, independent of how his life ended,” said Dr. Chris Nowinski, a former football player and professional wrestler turned neuroscientist, author and co-founder of the Concussion and CTE Foundation.
“I was playing through them until I couldn’t anymore, until I did too much damage to my brain,” Nowinski told Global News. “And I have never quite been exactly the same.”
Lemieux played a physical style over a 21-year NHL career that spanned nearly 1,500 games. It is not known whether chronic traumatic encephalopathy, or CTE, contributed to his death.
The degenerative brain disease — which can only be diagnosed after death — has been found in several former hockey players, including Henri Richard, Chris Simon and Bob Probert.
Experts say repeated head trauma can lead to a range of symptoms, including memory loss and severe depression.
“They become so depressed and have so many symptoms, like they can’t remember what they had for breakfast,” said Dr. Charles Tator, director of the Canadian Concussion Centre.
There is currently no cure or treatment that can slow or stop the disease.
Nowinski, a former athlete who retired after multiple concussions, said each brain donation is critical to advancing research.
“Each brain that’s donated is getting us closer to a cure while also giving us better insights on how to prevent this in the next generation,” he said.
Tator says prevention remains key, recommending that body checking be banned for players under 18, arguing older athletes are better equipped to protect themselves and make informed decisions.
He also noted athletes often resist safety measures.
“They are about the most non-compliant group of people you can imagine,” Tator said.
Despite the tragedy, experts say Lemieux’s legacy may ultimately help protect future players.
