Hall of Fame quarterback Brett Favre’s recent disclosure of his Parkinson’s disease diagnosis has reignited discussions about the potential links between collision sports and an increased risk of brain diseases. Favre revealed his condition on Tuesday while testifying before Congress regarding his alleged misuse of taxpayer money. Although the hearing focused on a welfare scandal in Mississippi, Favre’s health became a topic of interest when he mentioned losing an investment in a company he believed was making a “breakthrough concussion drug.”
“I’m sure you’ll understand why it’s too late for me because I’ve recently been diagnosed with Parkinson’s,” Favre said.
Favre played 20 seasons in the National Football League, mostly for the Green Bay Packers, and retired 13 years ago. In a 2022 interview with “The Bubba Army” radio show, he estimated that he had suffered thousands of concussions. “Every time my head hit the turf, there was ringing or stars going, flash bulbs, but I was still able to play,” he said in that interview. “That’s what’s kind of frightening about the concussion thing. It’s the ones that seem minor that do the damage.”
Sports that involve repetitive collisions—such as football, boxing, and rugby—carry a risk of concussions and other head injuries. “We know that the brain can only take so much, and when there’s this kind of trauma—not even just sports-related, but any kind of repeated trauma to the brain—we know it’s going to affect it down the line,” said Shannon Shaffer, a nurse practitioner at the Cleveland Clinic and liaison at Rune Labs, a neurology-focused software and data analytics company.
