CHICAGO (CBSMiami/AP) — The proof of a connection between playing football and brain injury is coming in as clear as day.
Research on 202 former football players found evidence of a brain disease linked to repeated head blows in nearly all of them, from athletes in the National Football League, college and even high school.
It’s the largest update on chronic traumatic encephalopathy, or CTE, a debilitating brain disease that can cause a range of symptoms including memory loss.
The report doesn’t confirm that the condition is common in all football players; it reflects high occurrence in samples at a Boston brain bank that studies CTE.
