That's correct, we know that COVID can and does have an effect on the brain but we don't know the extent of what it does or how it relates to what people colloquially call Long COVID. That said, it's always disappointing to see people push quackery like dietary fixes or claiming it's just a sociological thing. Especially the sociological angle because it isn't just limited to places like the US (where I presume people are pushing the theory for political reasons). It appears in places regardless if they did full on lockdowns or did a more light touch like in Sweden. It makes me think that nowadays people would claim Shingles is fake and made up and unrelated to Chicken Pox.
