Coexistence of SARS-CoV-2 and cerebrovascular diseases: does COVID-19 positivity trigger cerebrovascular pathologies?

Abstract

The objectives of this study were to determine the prevalence of cerebrovascular diseases caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, and to assess the pharmacological agents used in such cases as reported in the literature. Patient files were retrospectively scanned to determine the prevalence of neurological symptoms of the central nervous system (headache, dizziness, lack of smell and taste, numbness in arms and legs, change in consciousness, muscle weakness, loss of urine and stool control) and cerebrovascular diseases (ischemic cerebrovascular diseases, cerebral venous sinus thrombosis, intracerebral hemorrhage, subarachnoid/subdural hemorrhage) in 2019 novel coronavirus (2019-nCoV) disease (COVID-19) cases (n = 20,099). The diagnostic laboratory, radiology examinations and treatments applied to these cases were recorded. The data from studies presenting cerebrovascular diseases associated with SARS-Cov-2, which constituted 0.035% of all cases, were systematically evaluated from electronic databases. During the treatment of cerebrovascular diseases, it was discovered that high doses of enoxaparin sodium anti-Xa are combined with apixaban or acetylsalicylic acid or clopidogrel or piracetam, and mannitol, in addition to SARS-CoV-2 treatment modalities. While neurological symptoms of the central nervous system are uncommon in cases of SARS-CoV-2 infection, cerebrovascular diseases are far less common, according to the findings of this study. Acute cerebral ischemia was discovered to be the most common cerebrovascular disease associated with SARS-CoV-2. The mortality rate increases with the association between SARS-CoV-2 and cerebrovascular disease.
