Aaron Hernandez was a victim of the most severe form of chronic traumatic encephalopathy (CTE) discovered in someone his age, The Washington Post reports. And on Thursday, McKee shared additional findings from her examination of Hernandez's brain.

In April he committed suicide by hanging in a MA prison while serving a life sentence for Odin Lloyd's 2013 murder.

Aaron Hernandez's brain scan shows severe damage to the parts of his brain responsible for memory, behavior and impulse control.

Ann McKee is the head of BU's CTE Center, one that's been studying the disease for more than a decade.

Hernandez hanged himself in prison days after he was acquitted in the 2012 drive-by shootings of two men in Boston and just hours before his former teammates visited the White House to celebrate their latest Super Bowl victory.

The late National Football League players Junior Seau, Andre Waters and Dave Duerson all committed suicide, and all three were found to have CTE in their brains.

Jose Baez, Hernandez's attorney, sued the National Football League and the Patriots in September on behalf of his client's daughter. Other parts, like the hippocampus, had begun to shrink and large holes were found in his brain's membrane, McKee said.

According to the AP, McKee did not say Hernandez's behavior was a result of CTE, but McKee did say the frontal lobe of Hernandez's brain had substantial damage. "We've never seen this in our 468 brains, except in individuals some 20 years older", she said.
