A recent study has revealed alarming statistics regarding the health conditions of former NFL players, specifically in relation to chronic traumatic encephalopathy (CTE), a progressive brain disease linked to repeated head injuries. This research, conducted by a collaborative team from Boston University, Mass General Brigham, and the Concussion & CTE Foundation, was published in the JAMA Network Open on October 28.

The study scrutinised the cases of 2,362 former NFL players and found that approximately 75% of those who passed away between 2008 and 2023 were diagnosed with CTE. This marks a significant increase from a previous study published in August, which estimated that between 25% and 98% of NFL players who died from 2016 to 2021 were similarly affected by the condition.
CTE is characterised by the gradual degeneration of brain cells, often stemming from repeated head trauma, a common occurrence in contact sports such as American football. The condition is assessed in stages, complicating the understanding of its prevalence and the extent to which it might interact with other diseases that may have contributed to the deaths of the individuals studied.
Julia Gallini, the lead author and a PhD candidate at Boston University’s School of Public Health, emphasised the importance of these findings. “Providing a precise estimate for the prevalence of CTE among deceased NFL players helps define the scale of the problem and informs priorities for the potential current and future medical needs of this community,” she stated in a press release.
The study also notes that the brains examined were predominantly from players who had lengthy careers and generally died at a younger age. A staggering 94% of the studied brain donors had CTE, drawing attention to the severe implications of exposure to head injuries in professional football.
These findings raise concerns not only about the health of current NFL players but also about extending this research to college and high school athletes. The study’s limitations mean it does not address the prevalence of CTE in living players nor does it provide insights into younger athletes who might be at risk.
In response to the study, the NFL reiterated its commitment to enhancing player safety, stating it continuously seeks to reduce concussions and related injuries. “The NFL remains committed to ensuring that the NFL community has access to a robust – and expanding – set of resources to enhance their physical and mental well-being,” the league asserted in a statement to the media.
The NFL Players’ Association (NFLPA), which represents NFL players, also offered its perspective on the study. The organisation recognised the significance of such research for understanding the long-term impacts of football on health. “Studies like this are critical to improving our understanding of football’s long-term impacts,” the NFLPA noted, reasserting its commitment to supporting research and resources that improve player health and well-being during and after their careers.
These emerging figures paint a troubling picture for the future of American football, raising urgent questions about the safety protocols in place and the responsibilities of leagues, teams, and governing bodies in safeguarding players’ health. With the alarming prevalence of CTE among former players now firmly on the table, it remains imperative for stakeholders in the sport to focus on effective strategies for prevention and support for affected individuals and their families.
As discussions continue around the implications of CTE, the need to increase awareness, diagnosis, and treatment options has never been more pressing. Athletes, medical professionals, and sports organisations must unite to ensure that the health risks associated with the sport are addressed comprehensively, paving the way for safer practices in football and other contact sports.
