Neurological Complications of the COVID-19 Pandemic: What Have We Got So Far?
Adv Exp Med Biol. 2021;1321:21-31. doi: 10.1007/978-3-030-59261-5_2.ABSTRACTThe recently emerged coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of COVID-19, is the newest threat to human health. It has already infected more than 54.5 million people worldwide, currently leading to more than 1.3 million deaths. Although it causes a mild flu-like disease in most patients, lethality may increase to more than 20% in elderly subjects, especially in those with comorbidities, like hypertension, diabetes, or lung and cardiac disease, and the mechanisms are still elusive. Common symp...

Does a history of cardiovascular disease or cancer affect mortality after SARS-CoV-2 infection?
Tidsskr Nor Laegeforen. 2020 Dec 29;140(2). doi: 10.4045/tidsskr.20.0956. Print 2021 Feb 2.ABSTRACTBACKGROUND: Cardiovascular disease and cancer have been described as possible risk factors for COVID-19 mortality. The purpose of this study was to investigate whether a history of cardiovascular disease or cancer affects the risk of dying after a COVID-19 diagnosis in Norway.MATERIAL AND METHOD: Data were compiled from the Norwegian Surveillance System for Communicable Diseases, the Norwegian Cardiovascular Disease Registry and the Cancer Registry of Norway. Univariable and multivariable regression models were used to calcul...

Pharmacological and cardiovascular perspectives on the treatment of COVID-19 with chloroquine derivatives.
Abstract The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) and an ongoing severe pandemic. Curative drugs specific for COVID-19 are currently lacking. Chloroquine phosphate and its derivative hydroxychloroquine, which have been used in the treatment and prevention of malaria and autoimmune diseases for decades, were found to inhibit SARS-CoV-2 infection with high potency in vitro and have shown clinical and virologic benefits in COVID-19 patients. Therefore, chloroquine phosphate was first used in the treatment of COVID-19 in China. Later, under a lim...

Etiologic Subtypes of Ischemic Stroke in SARS-CoV-2 Patients in a Cohort of New York City Hospitals
Conclusion: COVID-19-related ischemic events can present as small vessel occlusions, branch emboli or large vessel occlusions. The most common etiology is cryptogenic. Patients with LVO syndromes tend to be younger, male and may have elevated acute inflammatory markers.

The potential role of microvascular pathology in the neurological manifestations of coronavirus infection
We present the hypothesis that pre-existing vascular damage (due to aging, cardiovascular disease, diabetes, hypertension or other conditions) facilitates infiltration of the virus into the central nervous system (CNS), increasing neuro-inflammation and the likelihood o f neurological symptoms. We also discuss the role of a neuroinflammatory cytokine profile in both blood–brain barrier dysfunction and macrovascular disease (e.g. ischemic stroke and thromboembolism). Future studies are needed to better understand the involvement of the microvasculature in coronavi rus neuropathology, and to test the diagnostic potential o...

Characteristics and predictors of hospitalization and death in the first 11  122 cases with a positive RT-PCR test for SARS-CoV-2 in Denmark: a nationwide cohort
ConclusionsIn this nationwide population-based COVID-19 study, increasing age and multimorbidity were strongly associated with hospitalization and death. In the absence of co-morbidities, the mortality was, however,<5% until the age of 80  years.

Coagulopathy and thromboembolic events in patients with SARS-CoV-2 infection: pathogenesis and management strategies
AbstractIn October 2019, a viral infectious disease appeared in the city of Wuhan in China. A new betacoronavirus, SARS-CoV-2, has been recognized as the responsible pathogen in this infection. Although coronavirus disease is principally expressed as a pulmonary infection, critical SARS-CoV-2 infection is frequently complicated with coagulopathy, and thromboembolic events are recognizable in several patients. Dehydration, acute inflammatory condition, protracted immobilization during disease, existence of multiple cardiovascular risk factors such as diabetes, obesity or hypertension, previous coronary artery disease, ische...

Spectrum of Neurological Manifestations in Covid-19: A Review
Ravindra K GargNeurology India 2020 68(3):560-572 COVID-19, in most patients, presents with mild flu-like illness. Elderly patients with comorbidities, like hypertension, diabetes, or lung and cardiac disease, are more likely to have severe disease and deaths. Neurological complications are frequently reported in severely or critically ill patients with comorbidities. In COVID-19, both central and peripheral nervous systems can be affected. The SARS-CoV-2 virus causes the disease COVID-19 and has the potential to invade the brain. The SARS-CoV-2 virus enters the brain either via a hematogenous route or olfactory system. A...

COVID-19 Infection and Neurological Complications: Present Findings and Future Predictions
The present outbreak caused by SARS-CoV-2, an influenza virus with neurotropic potential, presents with neurological manifestations in a large proportion of the affected individuals. Disorders of the central and peripheral nervous system are all present, while stroke, ataxia, seizures, and depressed level of consciousness are more common in severely affected patients. People with these severe complications are most likely elderly with medical comorbidities, especially hypertension and other vascular risk factors. However, postinfectious complications are also expected. Neurological disorders as sequelae of influenza viruse...

SARS-CoV-2 infection of the nervous system: A review of the literature on neurological involvement in novel coronavirus disease (COVID-19).
In conclusion, SARS-CoV-2 infection can cause multiple neurological syndromes in a more complex presentation. Therefore, this review elucidated the involvement of the nervous system in SARS-CoV-2 infection and will hopefully help improve the management of COVID-19.
