One of the least understood effects of COVID-19 infection is “brain fog,” a kind of mental confusion that can take hold among seriously ill patients, sometimes lingering long after recovery.

Now, a new study has spotted a possible neurological clue in the form of highly unusual cell clusters in the brains of people who had COVID-19.

“What we’re talking about is a situation where patients feel fuzzy and foggy in their thoughts,” said study lead author Dr. David Nauen.

“It’s when you’re extremely tired and sluggish, and your mental activity just doesn’t seem to be working as crisply and sharply as usual. And it’s been reported among COVID-19 patients still under care and afterwards, during the long recovery phase,” he explained.

“We thought it must be due to something affecting the brain, because we know other viruses can certainly affect the brain, sometimes with severe neurologic consequences,” said Nauen, who’s an assistant professor in the department of pathology at Johns Hopkins University, in Baltimore.
