34 of the 35 brains donated by former NFL players had CTE.
The largest study of CTE, a brain disease caused by repeated hits to the head, was conducted at Boston University. They were able to break down stages of CTE based on damage inflicted upon the brain. CTE causes confusion, depression and dementia.
Of note, 34 of the 35 brains donated by NFL football players for the study were found to have CTE.
Of the 85 brains donated by the families of deceased veterans and athletes with histories of repeated head trauma, they found CTE in 68 of them. Of those, 34 were professional football players, nine others played college football and six played only high school football.
Six only in high school. That is going to scare parents. The NFL must be at the forefront of concussion research, if only for self-survival.
