At the conference Thursday, McKee flipped through slides comparing sections of Hernandez’s brain to a sample without CTE. Hernandez’s brain had dark spots associated with tau protein and shrunken, withered areas, compared to pristine white of the sample. But she found the advanced stage of CTE in Hernandez’s brain alarming. “We know that that’s a risk factor for neurogenerative disease,” McKee said. Researchers had previously disclosed severe signs of CTE in Hernandez’s brain, indicating his brain had degenerated to a degree typically associated with a person in his late 60s.
