Doctor: Hernandez’s brain was severely damaged by disease
BOSTON — Former New England Patriots player Aaron Hernandez suffered substantial damage to parts of the brain that affect memory, judgment and behaviour from the most severe case of a degenerative disease linked to head blows ever found in someone so young, a researcher said Thursday.
Dr. Ann McKee, director of Boston University’s CTE Center, stressed she could not “connect the dots” between the brain disease chronic traumatic encephalopathy and the behaviour of the 27-year-old who hanged himself in April while serving life in prison for murder.
But McKee said CTE had significantly impacted key parts of Hernandez’s brain, including the hippocampus — which is associated with memory — and the frontal lobe, which is involved in impulse control, judgment and behaviour.
“We can say collectively, in our collective experience, that individuals with CTE — and CTE of this severity — have difficulty with impulse control, decision-making, inhibition of impulses or aggression, often emotional volatility and rage behaviours,” said McKee, who has studied hundreds of brains from football players, college athletes and even younger players, donated after their deaths.
