BOSTON — Aaron Hernandez suffered the most severe case of chronic traumatic encephalopathy ever discovered in a person his age, damage that would have significantly affected his decision-making, judgment and cognition, researchers at Boston University revealed at a medical conference Thursday.
Ann McKee, the head of BU’s CTE Center, which has studied the disease caused by repetitive brain trauma for more than a decade, called Hernandez’s brain “one of the most significant contributions to our work” because of the brain’s pristine condition and the rare opportunity to study the disease in a 27-year-old.
Hernandez, a former New England Patriots tight end, hanged himself with a bedsheet in April in a Massachusetts prison while serving a life sentence for the murder of his friend Odin Lloyd in 2013.
In a diagnosis that linked one of football’s most notorious figures with the sport’s most significant health risk, doctors found Hernandez had Stage 3 CTE, which researchers had never seen in a brain younger than 46 years old, McKee said. Because the center has received few brains from people Hernandez’s age, McKee could not say whether Hernandez’s brain was representative of a 27-year-old who had played football as much as Hernandez. But she found the advanced stage of CTE alarming.
It just seems like you're rolling the dice, and the cost/benefit ratio is not that good.
