This study was great because they had data from before COVID that was just part of the Bio Bank, so they were able to review participants already in the bio bank based COVID status. 394 COVID patients and 388 controls. Based on a small sample size of only 15 that were hospitalized, it also appears to increase grey matter loss based on severity, although sample size is not large enough to say so conclusively.

- eightysixfour 5y agoYou’ll have your perfect data in around 5 years. In the mean time, there is significant evidence that suggests COVID impacts the brain. You can ignore it or argue against it all you want, but it is there.
