At least 1-in-4 ex-NFL players who died from 2016 to 2021 had CTE, study finds

A new study by Mass General Brigham reveals that at least one-in-four former NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy, known as CTE. This brain disease is linked to repeated blows to the head. The findings indicate that nearly 25% of these athletes were affected, representing a significantly higher rate of the condition than is typically observed in the general population. Dr. Céline Gounder provided further details on these specific results.
