Note: I have friends who thankfully survived infection now affected by this phenomenon. The article thus grabbed my attention.

SARS-CoV-2 appears to travel widely across the cerebral cortex

“Brain fog” is not a formal medical descriptor. But it aptly describes an inability to think clearly that can turn up in multiple sclerosis, cancer, or chronic fatigue. Recently, the condition has grabbed headlines because of reports that it afflicts those recovering from COVID-19.

COVID’s brain-related symptoms go beyond mere mental fuzziness. They range across a spectrum that encompasses headaches, anxiety, depression, hallucinations, and vivid dreams, not to mention well-known smell and taste anomalies. Strokes and seizures are also on the list. One study showed that more than 80 percent of COVID patients encountered neurological complications.

The mystery of how the virus enters and then inhabits the brain’s protected no-fly zone is under intensive investigation. At the 50th annual meeting of the Society for Neuroscience, or SFN (held in virtual form this month after a pandemic hiatus in 2020), a set of yet-to-be-published research reports chronicle aspects of the COVID-causing SARS-COV-2 virus’s full trek in the brain—from cell penetration to dispersion among brain regions, to disruption of neural functioning.
