> Surprising that having more AMPA receptors would lead to decreased cognition

The study only looked at one marker. It doesn't confirm that increased AMPA receptor density is the cause of decreased cognition. It only suggests that decreased cognition is correlated with increased AMPA receptor density.

There are many processes in the body where reduced activation of a receptor system results in an increased number of those receptors. So don't conclude that this is the reason why patients have brain fog. I would guess it's just more of a symptom than a cause until there's more research
