Encephalitis secondary to SARS-CoV-2 infection

Abstract

Introduction: All the methodological processes that involve the discussion about the neurological complications of Covid-19, and in particular encephalitis, indicate that although the clinical characteristics most observed in patients infected with SARS-CoV-2 are associated with the respiratory system, systemic and systemic changes can also occur in these patients. Methodology: This is an integrative literature review study carried out in the VHL, PMC and IPTODATE, which are online databases of the virtual health library. The following scientific descriptors were used to capture the sample: “Encephaliti”, “viral Encephalophaty” and Covid-19”. The study sample consisted of 54 articles, of which only 19 articles published between the dates of September 2020 and August 2021 comprised the study sample after applying the eligibility criteria. National and international articles available in full were included. Results: The results presented were of great significance regarding the learning of theoretical and practical concepts in the discipline about the occurrence of neurological impacts of Covid-19. Discussion: The study of the subject allowed to observe the neurological complications of covid infection 19, mainly regarding encephalitis and the mechanisms in which Sars-CoV-2 has to reach the central nervous system, its epidemiology, clinical manifestations and treatment. Conclusion: Therefore, it was shown how Sars-CoV-2 virus infection can result in encephalitis, in addition to presenting important data such as its main signs and symptoms, its prevalence and treatment. However, there is still little literature that addresses these repercussions of Covid-19, mainly related to encephalitis. Therefore, more in-depth approaches and research are needed in order to better understand the mechanisms related to the entry of the virus into the central nervous system and how it generates such complications.
