Neurological symptoms have been sporadically reported in COVID-19 patients but have not yet been well studied [48,49]. The current body of evidence suggests that the SARS-CoV-2 can affect the nervous system in previously unsuspected ways [50]. The neuroinvasive capabilities of the SARS-CoV-2 doubtless exist but remain to be elucidated. Observed neurological symptoms of COVID-19 include febrile seizures, convulsions, mental status changes, and encephalitis [51]. Among the most commonly reported possibly neurological symptoms of COVID-19 are nonspecific symptoms, such as headache, myalgia, dizziness, and fatigue [21]. In a study at a single center in China (n = 214), 36.4% (n = 78) of hospitalized COVID-19 patients had what were identified as neurological symptoms[52]. In a multicenter retrospective study from Europe of 417 patients who recovered from mild to moderate COVID-19, 86% reported olfactory dysfunction and 88% problems with taste. In fact, in 12% of patients, the loss of the sense of smell was the first symptom of COVID-19 [53]. The loss of smell has emerged as being more prevalent among patients infected with COVID-19 than patients infected with other viruses or with other types of respiratory conditions [54] and has been recommended as a symptom that may help guide earlier diagnosis and treatment of COVID-19 [55]. In a meta-analysis (n = 1,627 patients, 10 studies), a loss of the sense of smell was reported in 53% of COVID-19 patients [55].
