>> A new turn in the Aaron Hernandez saga. Doctors say the former football star, who was found dead inside a prison cell last April, suffered the worst case of chronic traumatic encephalopathy they've ever seen in a 27 year old. The brain disease is more commonly known as CTE.
>> I can say that this is substantial damage that undoubtedly took years to develop.>> Boston University's CTE Center researchers diagnosed the New England Patriots tight end after his suicide in jail, where he was serving a life sentence for murder. Hernandez was found guilty of murder in 2015, for the death of Odin Lloyd, who was dating the sister of Hernandez's fiance.
Hernandez was later charged and acquitted in two more killings. CTE is linked to repeated head trauma and can lead to aggression and dementia. Dr. Ann McKee says she can't say whether the CTE contributed to Hernandez's crime, but she does say that his frontal lobe, which is responsible for decision making, judgement, and cognition was damaged.
Slides also showed damage to the brain's inner chambers and the septum, damage never before seen in someone of Hernandez's age.>> This would be the first case we've ever seen of that kind of damage in such a young individual.>> The Hernandez family is currently suing the NFL, accusing the league of failing to warn former tight end about the sport's dangers.
The NFL has vowed to fight the suit.
