According to the attorneys, the former New England Patriot player “had a horrendous existence” as a result of chronic traumatic encephalopathy (CTE), a degenerative brain disease resulting from repeated head trauma. The 86-page civil complaint filed on Monday claimed the football tight end received several blows to the head while wearing the Riddell helmets, as a result he suffered from Stage 3 CTE, People reported.

"Aaron experienced a chaotic and horrendous existence in many respects, due to his [previous] undiagnosed brain injury,' the complaint said, adding the symptoms of the brain disease, “aggression, explosive behavior, loss of concentration, mood swings, depression, apathy, and cognitive impairment.”

Back in September, attorney Jose Baez revealed that Hernandez had the "most severe case" of a degenerative brain disease for football players his age. 

Although the NFL has yet to comment on the latest lawsuit, a spokesperson from Riddell said that they plan to defend themselves and added that they'd worked to "enhance concussion mitigation [in helmets] and awareness" more than 15 years ago, New York Post reported.

Back in April, Hernandez hanged himself in his prison cell using a bedsheet that he attached to his cell window. His suicide came five days after the former NFL player was acquitted of killing two men in 2012. The tight end was serving a life sentence without the possibility of parole for the 2013 murder of Odin Lloyd.
