At least one in four NFL players has CTE when they die, according to a new study that examined the brains of former pro football players. CTE is a brain disease thought to be caused by years of sustained head trauma and can only be diagnosed after an autopsy of the brain. amna speaks to Chris Nowinski, Ph.D., a co-author of the study, for more.

If you've watched football this season, you've probably seen the new State Farm ad with Giants RB Cam Skattebo. It shows him repeatedly smashing his head into things during his daily life off the field. This comes after his comment earlier this year that “CTE isn’t real; it’s an excuse.” For the families I speak with every day, CTE is no laughing matter. CTE is a real, progressive brain disease associated with repetitive head impacts. It can profoundly affect a person’s cognition, behavior, mood, and quality of life, and its consequences extend far beyond the individual diagnosed. For these families, there is nothing funny about the devastating toll of CTE.

My take on Giants RB Cam Skattebo saying CTE is not real? Disrespectful. He's since apologized calling it a “tasteless joke,” but as someone who knows the stories & the families of the almost 400 NFL players diagnosed with CTE, there is nothing funny about it. Skattebo has been given a gift by these families - the gift of knowledge. He now knows he's at risk for CTE. Those who built the NFL did not. He benefits from their support of CTE research. We need football players like him to stop denying the science and join us in the fight to end the disease so we can find a cure in their lifetime.

Michael Brooks, a former teammate of mine at Harvard in 1999, passed away last November at just 45 years old. He was the second member of our team diagnosed with CTE, and the first person under age 50 in the UNITE Brain Bank diagnosed with CTE with limbic-predominant age-related TDP-43 encephalopathy (LATE), named as such because it usually doesn't appear in the brain until after age 80. If you or a loved one is struggling with symptoms of suspected CTE, the Concussion & CTE Foundation HelpLine is here for you. Reach out at to get connected with free support and resources.

Today we announced, on behalf of the Kneeland family, that former Dallas Cowboys DE Marshawn Kneeland has been diagnosed with stage 1 CTE by our research collaborators at Boston University CTE Center. Kneeland died by suicide in November 2025 at 24 years old. Despite playing in the modern era of concussion protocols and better helmets, he still developed CTE. What that tells me is we have no reason to believe the current generation is at a lower risk of CTE than previous generations. Concussion protocols do not prevent CTE, because CTE is caused by repeated head impacts, not just concussions. If we want to reduce CTE risk, we must implement CTE prevention protocols and aggressively reduce the number and strength of head impacts at every level of the game. Suicide is complex and multifactorial. A post-mortem CTE diagnosis should not be considered the cause of a suicide and is not known to be a risk factor for suicide. We encourage anyone worried about suspected CTE symptoms to reach out to he Concussion & CTE Foundation HelpLine team for support at If you or someone you know is struggling, the 988 Suicide & Crisis Lifeline is available 24/7 by calling or texting 988.

I spoke with CTV News about the sudden passing of Chris Simon by suicide recently Chris was publicly suffering with CTE like symptoms because he played in the NHL the last professional sports league to deny a link between repetitive head trauma and neurodegenerative disease What did the NHLPA or NHLAlumni do to help him after he came out publicly in 2017, saying he was suffering with CTE and brain injury symptoms? We need to do better Onward

Football gave the University of Maryland Coach Michael Locksley a scholarship, a family and a career. But it also likely contributed to his son’s CTE diagnosis, the degenerative brain disease caused by repeated blows to the head.

Former Boston Bruins enforcer Lyndon Byers had stage 3 CTE. It’s heartbreaking, but sadly, it’s not surprising. For years, the science has continued to grow while NHL Commissioner Gary Bettman continues to deny the link between repetitive head impacts in hockey and CTE. Researchers at Boston University CTE Center have now diagnosed CTE in 19 out of the 20 former NHL players they’ve studied. This is not about attacking hockey. It’s about telling the truth, supporting players, and making sure the next generation doesn’t suffer in silence because the people in power refused to listen.
