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.”
Yes.
There are of course varying levels of inflammation so some are going to be worse than others. There are also different contributing factors, like high fevers that can also impact the brain in addition to the swelling.
So not completely unique to covid, but the way that it happens with covid is the concerning part.
