ABSTRACT
Taste disturbances are present in 20.3-88.0% of COVID-19 cases and are the first signs of infection in 11.0-18.1% of cases. They often manifested 3-7 days after the onset of general respiratory symptoms and last 2 to 16 days, followed by recovery. There are also prolonged disturbances of taste sensation (up to 61-76 days or more), which is associated with damage to various types of receptor cells of the mucous membrane of the tongue. More severe taste disturbances are recorded in the elderly. In women, changes in taste sensation are noted more often than in men, and with a longer recovery period. Severe and critical forms of taste disorders predominate in COVID-19; dysgeusia, as a rule, prevails over hypogeusia and ageusia. Taste disturbance is a common clinical symptom in COVID-19, which can and should be considered as a marker of early manifestation of coronavirus infection.

In a COVID-19 pandemic, a neurologist needs to be able to assess the risks of virus infection in patients with individual neurological diseases. The review presents categories of risk groups from the Association of British Neurologists for neuromuscular diseases, multiple sclerosis and other autoimmune diseases of the central nervous system, stroke, epilepsy and Parkinson's disease. The risk of infection and the management of patients with neuromuscular diseases are analyzed in detail. The use of multiple sclerosis disease modifying drugs, the treatment of stroke patients are discussed. The data from the international guidelines for the management of patients with epilepsy and Parkinson's disease are presented.
