From the article:
“…two new studies published in the New England Journal of Medicine shed further light on the profound toll of COVID-19 on cognitive health.” And in other studies cases “with mild to moderate COVID-19 showed significant prolonged inflammation of the brain and changes that are commensurate with seven years of brain aging.”
I definitely find it harder to think of words when I’m talking to people and it seems like something that came about after COVID. Also, I have a much shorter fuse now and seem to get annoyed almost randomly.
