Dear Readers! On behalf of the editorial board of the Korsakov Journal of Neurology and Psychiatry I congratulate you with the New Year 2021! The past year went down in history as the year of a new infectious respiratory disease, the coronavirus infection COVID-19, which swept the world in a few months and turned into a pandemic. The pandemic was a major challenge for all areas of clinical and basic medicine, including neuroscience, and focused all domestic and global health resources on helping the sick and developing effective treatment and prevention methods.
