Research shows that SARS-CoV-2 seemed to have a strong effect on the brain, causing everything from loss of taste and smell and brain fog to, in serious cases, stroke. Scientists are just beginning to understand COVID-19's effect on the brain:
not yet been peer-reviewed also found SARS-CoV-2 spike proteins—which are found on the virus’ surface and allow it to enter human cells—in the brains of people who died from COVID-19.
Dr. Wes Ely, who researches brain disease at Vanderbilt University Medical Center, says he’s convinced SARS-CoV-2 can attack the “support cells” of the brain, or those ensure neurons are able to keep the brain and body functioning normally. Damaging these support cells, Ely says, can kick off a domino effect that leads to tissue death in the brain.
While there may not be a single solution, that doesn’t mean there’s no solution. Ely has found that “cognitive rehab,” a process of rebuilding the brain’s function through targeted mental exercises, can help people who develop similar cognitive decline after stays in the intensive-care unit. That approach could be risky for people with Long COVID, many of whom experience
