I just heard on the radio: a scientific study that links the type of injury caused by TBI, especially war veterans, with the CTE experienced by some athletes. The bad news: TBI is now linked with a degenerative condition. The good news: they may have found a physical marker, specifically the TAU protein compacted into certain tissues, that can serve as a diagnostic tool.

I don't know if there's a way to detect these protein clumpings in vivo, but it's still exciting to know there's a real and discrete physical component to what we're suffering. Also, I believe the effects of the TAU protein are fairly well known, so it's a good one to "choose".

Here's the link: Does brain injury link NFL players, wounded warriors?
