A new study published on Wednesday estimates that about 75% of former NFL players who died over a 15-year period had evidence of chronic traumatic encephalopathy (CTE).
asserted
who → publish → encephalopathy
The research, published in Jama Network Open and conducted by a Boston-based team, examined the estimated prevalence of the degenerative brain disease among NFL players who died from 2008 through 2023.
asserted
who → publish → 2023
Researchers found that the estimated rate of CTE among these players was substantially higher than the rates observed in brain samples collected from the general population.
asserted
rate → find → population
The analysis included records from 2,362 deceased former NFL players who spent an average of five years in the league.
asserted
who → include → league
Of the nearly 400 players whose brains were donated for examination, 93.5% showed evidence of CTE.
asserted
% → donate → CTE
Researchers said the findings represented the first attempt to estimate how widespread CTE was among all former NFL players who died during the 2008-2023 period, rather than limiting the analysis to individuals whose brains were donated for research.
asserted
brains → say → research
Physical changes associated with the condition include brain atrophy, which involves the loss of brain tissue, and accumulations of tau protein, a characteristic also associated with Alzheimer’s disease.
asserted
which → associate → disease
The difference compared with the broader population was substantial.
asserted
difference → compare → population
According to the study’s authors, less than 1% of brain samples from community-based brain banks contain evidence of CTE.
uncertain
% → accord → CTE
However, the presence of CTE-related changes in the brain does not necessarily mean a person will develop dementia or experience declining cognitive abilities.
asserted
person → relate → abilities
Some individuals with the condition may never develop noticeable symptoms.
uncertain
individuals → develop → symptoms
Researchers estimated that approximately 27% of the former NFL players included in the analysis had dementia.
asserted
% → estimate → dementia
CTE can also damage areas of the brain responsible for emotional control and behavior.
asserted
CTE → damage → control
Potential symptoms include depression, memory problems, severe mood changes and other behavioral difficulties.
asserted
symptoms → include → depression
“We recognize these findings may cause concern for the community of living players and their families,” Yorghos Tripodis, the study’s senior author, said in a statement released by Mass General Brigham.
uncertain
Tripodis → recognize → Brigham
“We want them to know that we and others are standing by to provide support, and that we have hope for those living with CTE.
asserted
we → want → CTE
“Discoveries from the brain bank have already brought us significantly closer to a diagnosis during life, at which point our most important goal will be to develop effective treatments for CTE,” Tripodis added.
asserted
Tripodis → bring → CTE
The findings follow another study released in August, which determined that at least one in four of former NFL players who died between 2016 and 2021 had CTE.
asserted
who → follow → CTE
Following the publication of the earlier study, the NFL addressed its efforts to improve player safety in a statement: “The NFL continuously strives to make the game of football safer, including by implementing strategies to reduce concussions and head impacts.”
asserted
game → follow → concussions
A number of high-profile NFL players who took their own lives – including Junior Seau, Dave Duerson and Aaron Hernandez – were found to have had CTE when their brains were analyzed after their deaths.
asserted
brains → take → deaths
