NFL Players Face High Rates of CTE, New Study Finds

A recent study led by Massachusetts researchers highlights a concerning trend among former NFL players. It suggests that at least 25% of those who played professional football may develop chronic traumatic encephalopathy (CTE), a terminal brain disease diagnosed only after death.

The study, published in The BMJ, evaluated data from hundreds of NFL players who died between 2008 and 2021. Researchers focused on 338 brains of the over 1,700 players who died. They found that 315 of these showed signs of CTE. Importantly, the brains of players who passed away in the last six years were more often donated for research. Of these recent donations, over 210 out of 235 players were confirmed to have CTE.

Postmortem brain analysis remains the only definitive method for CTE diagnosis.

Understanding CTE

CTE significantly alters brain function. Research associates it with harmful protein build-up in the brain, causing cell death. Individuals with repetitive head trauma, such as football players, often have the disease. However, CTE is not restricted to football. It has been found in boxers, soccer and hockey players, military personnel, and first responders. Symptoms, which manifest years post-impact, can include cognitive difficulties, mood changes, and suicidal thoughts.

The CDC notes that these symptoms, while indicative of CTE, do not guarantee a diagnosis. Those experiencing these issues should consult a healthcare professional. Various treatments exist to manage symptoms.

Ongoing Research

Efforts to understand CTE’s development and risk factors are ongoing, as emphasized by Boston University. Their research aims to improve early diagnoses and explore potential interventions.

Notable Cases of CTE in NFL Players

Many former NFL players have posthumously received CTE diagnoses. A 2023 report noted that 345 out of 376 former NFL players examined by Boston University had CTE. Some notable players include:

• Former Dallas Cowboys defensive end Marshawn Kneeland: Diagnosed with Stage 1 CTE after his suicide in 2023.
• Aaron Hernandez: The former player, who died by suicide in 2017, had Stage 3 CTE.
• Frank Wycheck: The Tennessee Titan had Stage 3 CTE after his death in 2023 following a fall.
• Demaryius Thomas: Suffered from CTE-related symptoms until his death in 2021 and was later confirmed to have Stage 2 CTE.
• Irv Cross: The CBS anchor had Stage 4 CTE, as confirmed in 2021 after his death.
• Phillip Adams: Diagnosed with Stage 2 CTE after a shooting incident and his death in 2021.
• Shane Tamura: Though not an NFL player, his CTE was confirmed after a tragic incident in New York City.

The study and its findings reflect urgent attention needed on the potential long-term impacts of competitive sports, particularly those involving repeated head trauma.
