SOME ASPECTS OF ETHIOPATHOGENESIS OF NEUROLOGICAL MANIFESTATIONS IN CORONAVIRUS INFECTION AND STUDY OF THE EXPRESSION AND PREVALENCE OF SMELLAND TASTE IMPAIRMENTS IN PATIENTS WITH SARS-COV-2

Abstract

The new coronavirus SARS-CoV-2 and the disease it causes, COVID-19, along with damage to the respiratory system, sometimes leads to nervous system disorders. The loss of smell and taste in COVID-19 is most likely of a perceptual nature. Because of the active accumulation of information about the symptomatology of this nosology, data appeared on the characteristic manifestations of thedisease in mild and moderate cases, in particular, on the violation of taste and smell. Although there is currently insufficient data to determine the exact mechanisms of anosmia and ageusia in patients diagnosed with COVID-19, there are studies that support certain theories. This paper presents the results of a systematic database review of COVID-19 taste and smell disorders. The article analyzes information on the etiopathogenic aspects of the neurological manifestations of COVID-19 and data on the severity and prevalence of smell and taste disorders in patients with coronavirus.Keywords: COVID-19, SARS-CoV-2, novel coronavirus infection, loss of smell and taste, anosmia, hypogeusia, ACE2 receptors
