Study Finds High Incidence of CTE Among Former NFL Players

A new study indicates that at least one in four former NFL players has chronic traumatic encephalopathy (CTE) at the time of death. CTE is a brain disease believed to result from repeated head trauma, and it can only be diagnosed posthumously through an autopsy. The study, which involved examining the brains of 235 former players who died between 2016 and 2021, suggests that the actual prevalence of CTE among NFL players could be higher than reported. Dr. Chris Nowinski, co-founder and CEO of the Concussion and CTE Foundation, noted that the findings indicate a significant public health issue within the NFL and football in general. The study found that nearly two-thirds of the players with CTE exhibited symptoms such as dementia while alive. Nowinski emphasized the need for further research, particularly regarding younger players, including those in high school and college. He pointed out that while the NFL has implemented measures to enhance player safety, the size and strength of players have increased, potentially exacerbating the risk of head injuries. The average age of the players studied at the time of death was around 66 years, raising questions about the long-term impacts of playing football in earlier eras. Nowinski concluded that more efforts are needed to address the crisis of CTE in football and to develop effective treatments.
