An ex-NFL footballer who killed himself in April after he was acquitted in a double murder trial had a “severe case” of a neurodegenerative brain disease.
Aaron Hernandez, 27, suffered from chronic traumatic encephalopathy (CTE), a brain disease associated with head injury, his family lawyer said.
He was found hanging in a Massachusetts prison, where he was serving a life sentence for another murder.
Hernandez’s family had asked his brain to be tested for CTE.
His attorney, Jose Baez, disclosed the CTE revelation as he sued Hernandez’s former team, the New England Patriots, and the NFL on behalf of the athlete’s young daughter.
Researchers at Boston University, which studies the progressive degenerative disease that is found in people with a history of repetitive brain trauma, found Hernandez’s brain to be at “an advanced stage” of CTE, according to Mr Baez.
