Hernandez was diagnosed with CTE.
Earlier this year, Aaron Hernandez, who was serving a life sentence for murder, committed suicide in his jail cell.
On Thursday, the New York Times reported that Hernandez suffered from severe chronic traumatic encephalopathy, the degenerative brain disease that has been linked to repeated head truama.
According to the NYT report, Hernandez, 27, had the "the most severe case they had ever seen in someone of Aaron’s age."
From the report:
Aaron Hernandez, the former New England Patriots tight end who committed suicide in April while serving a life sentence for murder, was found to have one of the most severe forms of C.T.E.
A lawyer for Hernandez, Jose Baez, in announcing the result at a news conference Thursday, said doctors determined it was “the most severe case they had ever seen in someone of Aaron’s age,” which was 27.
Baez said the Hernandez family plans to sue the NFL.
Hernandez is the latest NFL star to have committed suicide and then be found with CTE, joining Dave Duerson and Junior Seau, among others.
