COVID19’s impact on the brain

By now we know that mortality is not the only outcome of COVID-19 disease. The virus can reach all of our organs, so a number of survivors continue to battle symptoms long after initial disease. How does SARS-CoV-2 reach organs? We have COVID19 doors (called ACE2 receptors) on almost all of our organs. The little spikes on the virus are keys to these doors. It takes about 10 minutes for COVID19 to open the door and make a cell its home. Once in, the virus starts multiplying eventually killing the cell (and sometimes even killing all the cells in the organ). On top of this, our immune system then “overreacts” to these cells dying causing even more problems. This has been documented to happen in almost every organ in the human body, even among those with asymptomatic disease.
