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 it does. Every time someone gets infected, it does more damage. And a lot of that damage is essentially permanent. eg. damage to blood vessels, heart tissue etc.
