Did you see the parts of the article where they say that the most severe, “consequential damage” is predominantly found in the elderly and most severely ill? You’re implying that people who have mild cases (>99% of all cases; remember: over 40% cases are so mild that they’re considered “asymptomatic”, and for every one case we detect, 10-20 others never even bother to be tested!) have some kind of neurological damage. That isn’t what this article says.

Aside from a very tiny group who had strokes (again, mostly elderly), this research shows predominantly mild symptoms that (e.g. headache, insomnia), which would not be expected to persist.

If you read past the headline, you will see that even this article makes it clear that the vast majority of patients have minimal symptoms:

” Another large-scale study, this one with 909 coronavirus patients in Madrid, showed that 90% of cases simultaneously experienced changes to, or the loss of, the sense of smell and taste. In most of these cases, these changes were the only clinical expression of coronavirus or were accompanied by other minor symptoms.”
