C.T.E. Found In Aaron Hernandez (Age 27) at Autopsy

What first occurred to me is that Aaron Hernandez was genetically vulnerable.
What that means is while he seemed far too young to have brain damage this advanced, the reality is that some people are simply at greater risk.
It’s a sad reality that this vulnerability wasn’t understood until autopsy.As we study further, we hope to be able to identify those like Aaron, before it’s too late
