ABSTRACT

Neurological complications of COVID-19 occur in almost a third of patients. According to various studies, the frequency of cerebrovascular manifestations in patients with a positive test result for SARS-CoV-2 ranges from 1% to 3%. The most common manifestation was acute ischemic stroke. Cerebrovascular complications in COVID-19 patients are likely multifactorial. They can be associated with coagulopathy, systemic inflammatory response, endothelial dysfunction and microthrombosis, as well as organ failure, impaired cardiac functions. The peculiarities of stroke in patients with COVID-19 include occlusion of large vessels, involvement of several vascular pools, a high incidence of damage to the vertebrobasilar system, a cryptogenic nature and a high severity of the course with high mortality and disability. Particular attention should be paid to impaired cognitive functions as a clinical manifestation of the consequences of stroke associated with a new coronavirus infection.
