Researcher: Hernandez’s brain severely affected by disease
BOSTON — Former New England Patriots player Aaron Hernandez suffered severe damage to parts of the brain that play an important role in memory, impulse control and behaviour, a researcher who studied his brain said Thursday.
Dr. Ann McKee, director of the CTE Center at Boston University, said she could not “connect the dots” between Hernandez’s severe case of chronic traumatic encephalopathy, which is linked to repeated blows to the head, and his behaviour. The 27-year-old hanged himself in April, while serving life in prison for murder.
But McKee said she says Hernandez experienced substantial damage to key parts of the brain, including the hippocampus — which is important to memory — and the frontal lobe, which is involved in problem solving, judgment and behaviour.
“In any individual we can’t take the pathology and explain the behaviour,” said McKee, who has studied hundreds of brains from football players, college athletes and even younger players, donated after their deaths. “But we can say collectively, in our collective experience, 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,” she said.
