Emery Brown, professor of medical engineering and neuroscience at Massachusetts Institute of Technology, likened the cognitive effects of coronavirus to those seen when patients awaken from deep sedation after major surgery. Clinical researchers thought that SARS-CoV-2 would infect the brain and that injury to the brain would be due, in part, to blood clots.
