Study shows Covid-19 affects brain size and function

A new international study shows that Covid-19 can have a significant effect on brain size and function. The study was carried out by several institutions including Oxford University and the United States National Institutes of Health. It examined hundreds of people aged between 51 and 81 who had tested positive for Covid-19. Brain imaging scans showed some of those infected saw "significant, deleterious" changes to their brains. Maurice Curtis is a Professor of Neuroscience and head of Auckland University's anatomy and medical imaging department. He says the study shows in some cases that brain size went down by six percent.
