We all recognize the typical signs and symptoms of COVID-19 (fever, shortness of breath, persistent non-productive cough). Less common symptoms are headaches, confusion (talking nonsense), numbness/hypoesthesia, seizure (convulsions), vomiting, loss of smell (anosmia), and sense of taste (ageusia). It can be noted that this group of symptoms consisted mostly of neurological complaints. COVID-19 causes CNS damage with various mechanisms. For example, anosmia or hyposmia is seen quite frequently among individuals even with mild COVID-19. Therefore, physicians should be alert in noting nervous system-related symptoms and findings that can be seen in the course of COVID-19.
