BOSTON — A Boston University researcher says the brain damage suffered by former New England Patriots player Aaron Hernandez was the most severe case she has ever seen for someone his age.
Doctor Ann McKee compared Hernandez’s brain scans to a typical 27-year-old.
She found damage to his frontal lobes which are important for impulse control, judgment and behavior.
Researchers also found large holes in his brain, which, they say is evidence of the advanced disease.
In the study, one hundred ten out of the one hundred eleven brains of former NFL players were found to have CTE.
“This acceleration-deceleration rotational injury happens despite the helmet it happens inside the skull,” McKee said. “It’s an intrinsic component of football.”
Hernandez played in high school and college before the New England Patriots drafted him in 2010.
But, in 2013, he was convicted of murdering a friend.
This spring, he hung himself in prison.
