Abstract
The issues of diagnosis and treatment of nervous system damage in the new coronavirus infection (COVID-19) remain relevant, regardless of information and experience in treating such patients, accumulated nowadays. The review contains updated data on the ways of SARS-CoV-2 invasion, examines mechanisms of central nervous system damage: direct virus-induced damage, immune dysfunction, excessive thrombo-inflammation, coagulation disorder, cytokine and metabolic imbalance, hypoxia, etc.; it presents clinical examples with one variant of damage — the development of Guillain-Barre syndrome that, to some extent, allows to confirm the virus neurotropism. Doctors’ knowledge about this infection is constantly expanding, new information appears on its various neuropsychiatric effects during an acute period and post-COVID syndrome, on symptoms, treatment and prevention strategy. These data enables to understand better the reasons for developing the main clinical manifestations, from a headache or myalgia to more severe symptoms, such as a stroke, psychosis and anosmia, severity and reversibility of their course. Although several hypothesis of CNS damage pathogenesis in COVID-19 are being discussed, the unified pathophysiological mechanism of many dysfunctions remains unclear, and, probably, additional factors, such as social isolation during a pandemic, presence and treatment in the intensive care unit, premorbid somatic status of a patient, contribute to the development of some registered nervous system disorders.
