We typically think of SARS-CoV-2, the pathogen that causes COVID, as a respiratory virus. That makes sense, given that it is airborne and typically infects humans via the nose and lungs, and causes respiratory symptoms like cough and sore throat. But maybe we should start thinking of SARS-CoV-2 as a brain virus, too.
After all, we have hard evidence that SARS-2 can infect the brain, causing long-lasting or even permanent damage. This can result in life-threatening strokes and encephalitis, inflammation of the brain, or what is colloquially called "brain fog."
