At least 25% of recently deceased NFL players had CTE, study finds

A new study found that at least 25% of former NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE), a brain disease linked to repeated head impacts. American football has long been associated with CTE, but the true prevalence of the condition has remained unclear. The findings add new data to the ongoing debate about the safety of contact sports.
