Ex-NFL star had 'severe' case of CTE brain disease: lawyer

State officials originally refused to release the brain because it was part of the ongoing investigation into Hernandez's death, but later agreed to release it after the ex-NFL star's lawyer accused them of holding the brain illegally.

Now, attorney Jose Baez tells PEOPLE the results show Hernandez suffered from chronic traumatic encephalopathy (CTE), a degenerative brain disease that has been linked to head trauma. According to Yahoo Sports' Dan Wetzel, Hernandez's family believes the CTE is related to his pro football career and is planning to sue not only the NFL but also the New England Patriots.

Shayanna filed the lawsuit in Mass. on behalf of the daughter she had with Aaron. Hernandez killed himself in April in the jail cell where he was serving a life-without-parole sentence for a 2013 murder.

"Aaron Hernandez had an advanced, stage 3 of CTE, which is normally found in the median age of a 67-year-old man", Baez said.

Attorney Jose Baez said that Boston University scientists said that he had one of the most severe cases of the neurological impairment CTE that they have ever seen.

Attorneys for Aaron Hernandez announced the results of a study of the late National Football League player's brain, which revealed he suffered from as Chronic Traumatic Encephalopathy, or CTE. CTE only can be diagnosed following death after examining brain tissue.

It was just after 3 a.m. a few days after he was acquitted on double murder charges when corrections officers found Hernandez hanging from a bed sheet.

"While we still maintain that he was innocent [of the murders], the CTE can explain a lot of his behavior", Baez says. Her research has demonstrated that CTE is associated with aggressiveness, explosiveness, impulsivity, depression, memory loss and other cognitive changes.

Baez said the results of a post-mortem study conducted on Hernandez's brain showed signs of a severe case of Chronic Traumatic Encephalopathy.

Per a technicality in MA state law, Hernandez's existing murder conviction was vacated due to him not going through the automatic appeals process that would have confirmed or overturned the 2015 conviction.
