Right, that is to diagnose CTE post-mortem. But does CTE also cause other phyiscal symptoms which are just indistinguishable from regular Alzheimer's? For instance, would a person with CTE also have visible plaques on an MRI, or is the disease really invisible in the living? The fact that they found CTE in 110 out of 111 NFL players post-mortem should indicate that they had a pretty good idea about which players to pick for autopsy. Was those picks based on their history of psychological issues alone, or were there other indicators such as definite signs of Alzheimer's?
