Even Mild Cases of COVID Can Cause Brain Damage and Shrinkage

Those who had COVID-19 had significantly more brain tissue loss and shrinkage, the researchers found. People typically lose around 0.2-0.3% of gray matter each year with normal aging, and those who had COVID-19 were losing far more, up to 2%. They also lost more overall brain volume and had higher amounts of tissue damage.

The damage was equivalent to at least an extra year of aging, Gwenaëlle Douaud, an associate professor at the Nuffield Department of Clinical Neurosciences at Oxford and the paper's lead author, told NBC News.

"It is brain damage, but it is possible that it is reversible," she said. "But it is still relatively scary because it was in mildly infected people."
