In some people, the SARS-CoV-2 infection causes an overreactive response of the immune system which can also damage body systems. Research shows the many neurological symptoms of COVID-19 are likely a result of the body’s widespread immune response to infection rather than the virus directly infecting the brain or nervous system. These strategies have included preventing infection with vaccines, treating COVID-19 symptoms with medicines or antibodies, and reducing complications in infected individuals. Much of the research to date has focused on the acute infection and saving lives. What do we know about the effects of SARS-CoV-2 and COVID-19 on the nervous system? When severe, this impairs the body’s ability to maintain critical levels of oxygen in the blood stream-which can cause multiple body systems to fail and can be fatal. It is most dangerous when the virus spreads from the upper respiratory tract into the lungs to cause viral pneumonia and lung damage leading to Acute Respiratory Distress Syndrome (ARDS). However, a new coronavirus called Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) emerged and spread to cause the COVID-19 pandemic.ĬOVID-19, which means Coronavirus disease 2019, is an infectious disease that can affect people of all ages in many ways. Coronaviruses are common causes of usually mild to moderate upper respiratory tract illnesses like the common cold, with symptoms that may include runny nose, fever, sore throat, cough, or a general feeling of being ill.
