For the first time since announcing former NFL star Aaron Hernandez’s CTE diagnosis in September, Boston University neuropathologist Dr. Ann McKee shared the findings from Hernandez’s brain autopsy on Thursday.

McKee and her team have examined more than 100 former NFL players’ brains for the neurodegenerative disease, formally named chronic traumatic encephalopathy, and found Hernandez’s case to be significant.
