Prevalence of CTE Among NFL Players Raises Concerns
A recent study reveals that at least 25% of NFL players who passed away over a five-year period were found to have CTE, although researchers believe the actual figures could be significantly higher.
CTE, characterized by cognitive decline and troubling personality changes such as aggression, confusion, and impaired judgment, can only be definitively diagnosed post-mortem through brain tissue examination. Not every former player donates their brain for such analysis, complicating the overall assessment.
Researchers from Mass General Brigham, Boston University, and the Concussion & CTE Foundation estimated the prevalence of CTE in deceased NFL players based on available data, revealing alarming potential statistics.
Between 2016 and 2021, during a period when brain donations surged, about one in four (or 24.5%) of those examined had CTE. This estimate, while conservative, could reach as high as 97.7%, though such a high figure seems improbable. Comparatively, only about 1% of the general population is affected by this condition.
Dr. Daniel Daneshvar, a lead author of the study, expressed feelings of both surprise and sadness at the high minimum estimate. “It’s unfortunate, but we recognized the high rate. We know the cause, and we can control the risk associated with it. Understanding this is crucial for risk mitigation,” he mentioned.
Understanding CTE
Chronic traumatic encephalopathy, or CTE, arises from repeated head trauma and has been identified in athletes across various sports, including ice hockey and boxing, as well as military veterans. However, it has particularly drawn attention in the context of the NFL.
Out of 878 former NFL players who died in the studied period, researchers examined the brains of 235. They found CTE in over 90% of these brains, with 30% exhibiting stage 4 CTE, the most severe form.
Severe CTE cases often correlate with dementia, showing significant decline in memory and cognitive abilities—a pattern that is typically easier to diagnose during a person’s lifetime. The researchers noted that nearly 60% of brain donors had dementia, with 18.6% listing neurodegenerative disease as the primary cause of death.
“Many experienced such severe cognitive impairment that they struggled with daily activities like grooming or self-care,” Daneshvar stated, reflecting on the distressing realities faced by many players.
The study coincided with the deaths of several high-profile NFL players under tragic circumstances, including suicides and struggles with substance abuse. For instance, in 2021, Philip Adams took the lives of six individuals and then himself, while Aaron Hernandez died by suicide in 2017. Wide receiver Vincent Jackson also succumbed to chronic alcoholism in 2021, which his wife noted was linked to his cognitive difficulties.
The NFL’s History with CTE
The NFL has faced scrutiny over player safety for many years. In 1994, it formed the Mild Traumatic Brain Injury Committee, which controversially claimed that serious injuries were unlikely in football and that recovery was fast.
Despite thousands of lawsuits for negligence, the league settled in 2013 for $765 million concerning the health of former players. In their response to the new study, the NFL stated their ongoing commitment to enhancing the safety of football, including reducing head impacts.
While much has focused on mitigating serious head injuries like concussions, researchers advocate for a broader approach to prevent CTE, emphasizing the need to minimize repeated head impacts.
Currently, there’s no direct treatment or cure for CTE. However, experts can address its symptoms through various methods, from physical therapy to behavioral treatments aimed at managing mood disorders. “Help is available,” Dr. Jesse Mez emphasized, noting that proper medical care can lead to improvement in symptoms.
