Is Your Brain Shrinks When You Get Covid?

Covid people often lose their sense of smell. They also see brain changes, and specifically reduction in gray matter density. We don't know if this is actually a permanent we still need to do follow ups of these very same people months and years later. Are the brain regions that usually process smells and process memories and smells, connect smells to all these other functions, just not being used? And then when we get our smell back again, do they just kind of bounce right back? It's an open question.
