Most people who get infected with the coronavirus recover within a few weeks. However, some continue to experience symptoms weeks or even months after they are infected. They have what are known as long-haul symptoms of COVID-19. As such, they are sometimes called COVID-19 long-haulers. Sometimes, even patients who had a mild or asymptomatic coronavirus infection can become long-haulers.
A growing body of scientific evidence suggests some COVID-19 patients will experience neurological signs or symptoms of the infection. Genetic material from SARS-CoV-2, the virus that causes COVID-19, has been found in the cerebrospinal fluid of a person with COVID-19. And the virus has been found in the brain tissue of patients who died of COVID-19, which suggests it can affect the nervous system.
