How COVID-19 Impacts the Brain When COVID-19 first emerged, it was assumed that the virus induces only lung disease, but more and more studies have shown that the whole body gets affected. Evidence shows that the brain and central nervous system (CNS) are affected by the virus. In a study of 214 COVID-19 patients 36% showed neurologic symptoms, such as CNS symptoms. Neurologic symptoms in patients with severe infections were even more common (45.5%). There is also evidence of patients without typical symptoms, such as fever, cough, anorexia and diarrhea, but neurologic manifestation. [1] Another study found that meningitis/encephalitis is associated with SARS-CoV-2. In one patient, the virus was not detected in nasopharyngeal swab, but in cerebrospinal fluid. [2] How exactly the virus affects the brain and nervous system is still unclear. Angiotensin-converting enzyme 2 (ACE2), the protein used by SARS-CoV-2 as a viral receptor for cell-entry, is expressed in both nervous system ...
