Intervention type: DIAGNOSTIC_TEST
Intervention: Neurological analysis
Description: Neurological examination with the isolation of neurological syndromes (motor, cognitive impairments, sleep disorders, asthenic-depressive syndromes, etc.).~2. Neuropsychological methods - research on the scales of anxiety and depression, MMSE, etc.~3. Instrumental method - EEG, polysonography, ultrasound of the neck vessels, CT perfusion.~4. Laboratory research methods:~1. The study of antibodies to some neurospecific antigens - myelin basic protein (MBP), neurospecific enolase (NSE).~2. Study of cellular immunity (CD3 +, CD4 +, CD8 +) and general indicators of humoral immunity (IgG, IgA, IgM, circulating immune complexes).

Intervention: Immunological analysis:
Description: A comprehensive immunological analysis will be carried out to determine the level of the immune response. Calculation of the level of CD4 +, CD8 + and NK cells. The level of antibodies of the IgG and IgM classes to the proteins of the coronavirus S1, RBD and N was determined

Intervention type: DIAGNOSTIC_TEST
Intervention: Genetic analysis:
Description: Isolation (extraction) of DNA will be performed from whole blood using commercial kits according to the manufacturer's instructions. To analyze a large number of genetic markers, it is planned to carry out genome-wide sequencing followed by analysis of genetic polymorphisms of candidate genes encoding coronavirus receptors and immunological factors.
