People who have even a mild case of Covid-19 may have accelerated aging of the brain and other changes to it, according to a new study.
The study, published Monday in the journal Nature, is believed to be the largest of its kind. It found that the brains of those who had Covid-19 had a greater loss of gray matter and abnormalities in the brain tissue compared with those who didn’t have Covid-19. Many of those changes were in the area of the brain related to the sense of smell.
“We were quite surprised to see clear differences in the brain even with mild infection,” lead author Gwenaëlle Douaud, an associate professor of neurosciences at the University of Oxford, told CNN in an email.
