ABSTRACT
The article is devoted to the study of vitamin D levels in patients who have had a coronavirus infection. As a result of the study, it was revealed that there is an inverse correlation between the severity of neurological complications after COVID-19 and the vitamin D content in the blood of patients who have undergone COVID-19, i.e. the lower the vitamin D content in the blood, the higher the probability of a severe course of postcovid neurological complications in the form of cephalgic syndrome.

ABSTRACT
Objective of the article is to provide more comprehensive data of the prevalence of neurological comorbid disorders and preexisting neurological disorders in patients with COVID-19. Method. We systematically searched the literature through Pubmed, based on the search of combination of keywords: Covid 19, coronavirus, neurological disorders, stroke, complications, neurorehabilitation. Results. The increased biomedical interest in the problem of COVID-19 is due to its high contagiousness, variable symptomatology, severe course and multiple organ failure in a pandemic, the critical importance of the state of the nervous system. The manifestations can be considered as direct effects of the virus on the nervous system, para-infectious or post-infectious immune-mediated disease, and neurological complications of the systemic effects of COVID-19. Conclusion. The article deals with brief aspects of some factors contributing to the development of neurological disorders in COVID-19 patients. The study results of coronavirus infection of foreign researchers are summarized.
