Can COVID make your brain shrink?

Al Jazeera  

A recent Oxford University study revealed changes in several parts of the brain after people contracted the virus, including those who experienced mild symptoms. Now, researchers at the University of Oxford have conducted the first major peer-reviewed study comparing the brain scans of 785 people, aged 51 to 81 of whom 401 had contracted COVID and 384 had not. The study revealed that, when compared to the scans of a control group, those who tested positive for COVID had greater overall brain shrinkage and more grey matter shrinkage and tissue damage in regions linked to smell and mental capacities months after the initial infection. The scans they did reveal changes in several parts of the brain after people contracted COVID, including: Greater reduction in grey matter thickness and tissue contrast in the orbitofrontal cortex and parahippocampal gyrus.
