Most NFL Players Who Donated Their Brains to Science Had Traumatic Injury

Prior to the Barrow-TGen test, the only way to diagnosis CTE was an autopsy.

The researchers studied the brains of 202 former athletes who had played football in the NFL, the Canadian Football League or at the college or high school level and found signs of CTE in the brains of 110 of the former 111 NFL players.

Safety advocates have long decried contact sports like hockey and football for causing irreparable, long-term damage to athletes at all levels.

The findings were based on the broadest review yet of the brains of former football players for signs of chronic traumatic encephalopathy. Most worrisome, even among those who only played football in high school, almost a quarter of them tested positive for that disease.

"There's a tremendous selection bias", McKee told The New York Times, explaining that a lot of the families donated brains because they noticed previous signs and symptoms of CTE exhibited by the former player. The disease was not found in brains from two younger players.

We took an online poll and asked parents if this recent CTE would affect their decision to let their child play football. He said problems other than CTE might explain some of their most common symptoms before death - depression, impulsivity and behavior changes.

The NFL responded to the new research in a statement reading in part, "The medical and scientific communities will benefit from this publication and the NFL will continue to work with a wide range of experts to improve the health of current and former NFL athletes". Of those diagnosed with CTE, 86% were found to have had a severe form of the condition. Wainright died in April 2016 at age 48 from a heart attack triggered by bleeding in the brain, said his wife, Stacie.

Shepard also said he expects his 14-month-old son to grow up wanting to play football.

Frank Wycheck, another former National Football League tight end, said he worries that concussions during his nine-year career - the last seven with the Tennessee Titans - have left him with CTE and he plans to donate his brain to research.

"That's not really my field", he said.

"Looking back on what we know now, no, I probably wouldn't", Korte said. Of the 14 deceased players who only played in high school, three showed mild cases of CTE.

A type of brain disease associated with repeated hits to the head was found in the brains of almost all of the deceased football players involved in a recent study. He believes the league and the players are becoming more concerned with the after effects of the game and possibilities of developing CTE in the years after leaving the game.
