Gordie Howe did suffer from dementia in the latter years of his life.
Of course he was 88 when he died so it was not necessarily hockey related.
Yup... If you get to 88 and you’re having a hard time finding your car keys, or remembering your children... That likely isn’t a result of concussions. Troy Aikman is 53 and having trouble finding his car keys... That IS a result of concussions... He had several, so I assume his head is pretty soft.
