My current theory on brain fog is that COVID is punching a hole in the BBB and that means all kinds material that is normal for you body but bad for your brain get in to it.

I don't think this is the ONLY cause of it, but I am led to believe it is a major driver.
Your BBB is like a filter that keeps all the stuff in your blood that doesn't belong in your brain out... 1/2
