Wasn't caffeine combined with contact sports linked to some brain damage?

I remember this being a thing going around - the proposed mechanism was that while caffeine helps in general, it constricts brain blood vessels making blows to head more dangerous, since blow to head "spills" stuff from neurons and due to the constriction they take longer to be resupplied. I remember some scientific articles on this but I don't recall if this was conclusive.

It might not be much of a concern for BJJ, where blows to head are relatively rare, but it for sure would be a concern for boxing or MT.

Contact sports and oats will be linked to some brain damage. Contact sports and listening to seagulls in the evening too will lead to brain damage.

I mean that’s true, but it’s still entirely possible that something like caffeine could make it worse.
