Former New England Patriots star Aaron Hernandez had a severe case of the degenerative brain disease chronic traumatic encephalopathy, researchers said on Thursday. His lawyer announced a lawsuit against the NFL and the team, accusing them of hiding the true dangers of the sport.
Dr. Ann McKee, the director of the CTE Center at Boston University, said Hernandez had stage 3 (out of 4) of the disease, which can cause violent mood swings, depression and other cognitive disorders.
“We’re told it was the most severe case they had ever seen for someone of Aaron’s age,” attorney Jose Baez said.
Hernandez was 27 when he killed himself in April in the prison cell where he was serving a life-without-parole sentence for murder. Baez said Hernandez had shown signs of memory loss, impulsivity and aggression that could be attributed to CTE.
“When hindsight is 20-20, you look back and there are things you might have noticed,” he said. “But you don’t know.”
CTE, which can be diagnosed only in an autopsy, has been found in former members of the military, football players, boxers and others who have been subjected to repeated head trauma. A recent study found signs of the disease in 110 of 111 NFL players whose brains were inspected.
The lawsuit filed in U.S. District Court claimed that the league and the Patriots failed to protect their players’ safety, leading to the disease that deprived Hernandez’s 4-year-old daughter, Avielle, of her father’s companionship.
“Defendants were fully aware of the dangers of exposing NFL players, such as Aaron, to repeated traumatic head impacts,” the lawsuit said. “Yet, defendants concealed and misrepresented the risks of repeated traumatic head impacts.”
