So this little pretty was published at Bloomberg News about brain shrinkage in long Covid, titled "COVID Can Shrink the Brain as Much as a Decade of Aging, Study Finds." The New York Times titled the story a bit more calmly, though still slightly alarming:"COVID May Cause Changes in the Brain, New Study Finds." The actual article in Nature is titled even more accurately, noting that this is an observation from banked bio-data in the UK: "SARS-CoV-2 is Associated with Changes in Brain Structure in UK Biobank."
Decide for yourself.
It might just be that I'm a little touchy on the matter of not having the brain power I had before long COVID.
