As I have discussed in detail in my previous blog in our long COVID series, residual virus is not thought to be the only problem we face relevant to ongoing neurological issues following an infection. Medical News Today reported in a new perspective article, based on clinical observations, autopsies, and lab findings by a team of researchers in Chicago, which argues against the virus directly affecting brain cells. Instead, it appears that the brain is affected by systemic inflammation and circulatory problems.1
