It becomes apparent that the neurological complications of COVID-19 are significantly common, but in some cases, establishing a causal relationship is difficult. For example, a stroke can occur for reasons unrelated to coronavirus infection, while Guillain–Barré syndrome and meningoencephalitis are likely to be a parainfection. Only long-term epidemiological studies in large groups of patients can clarify some of these issues. This will help to better understand the mechanisms of development of complications and develop schemes for their treatment and subsequent rehabilitation. The article presents the mechanisms of penetration of the coronavirus into the nervous system and systematizes the neurological manifestations and complications of COVID-19, which were described in the first 3 months of the pandemic. Particular attention is paid to the consideration of the complications of COVID-19 from the central and peripheral nervous system, the most interesting clinical examples are considered. Summing up the analysis of the literature, we can say that the clinical picture of neurological diseases and syndromes caused by coronavirus infection corresponds to the usual notions. Also considered is the assumption that SARS-CoV-2 can persist for a long time in the central nervous system in the form of inactive fragments, which means that it can recur in predisposed individuals when appropriate conditions arise. This suggestion is alarming regarding distant neurological complications in infected and cured patients.

The Impact

Increasing evidence suggests that Severe Acute Respiratory Syndrome-coronavirus-2 (SARS-CoV-2) can also invade the central nervous system (CNS). However, findings available on its neurological manifestations and their pathogenic mechanisms have not yet been systematically addressed. A literature search on neurological complications reported in patients with COVID-19 until June 2020 produced a total of 23 studies. Overall, these papers report that patients may exhibit a wide range of neurological manifestations, including encephalopathy, encephalitis, seizures, cerebrovascular events, acute polyneuropathy, headache, hypogeusia, and hyposmia, as well as some non-specific symptoms. Whether these features can be an indirect and unspecific consequence of the pulmonary disease or a generalized inflammatory state on the CNS remains to be determined; also, they may rather reflect direct SARS-CoV-2-related neuronal damage. Hematogenous versus transsynaptic propagation, the role of the angiotensin II converting enzyme receptor-2, the spread across the blood-brain barrier, the impact of the hyperimmune response (the so-called “cytokine storm”), and the possibility of virus persistence within some CNS resident cells are still debated. The different levels and severity of neurotropism and neurovirulence in patients with COVID-19 might be explained by a combination of viral and host factors and by their interaction.

COVID-19 has spread rapidly worldwide since its outbreak and has now become a major public health problem. More and more evidence indicates that SARS-CoV-2 may not only affect the respiratory system but also cause great harm to the central nervous system. Therefore, it is extremely important to explore in-depth the impact of SARS-CoV-2 infection on the nervous system. In this paper, the possible mechanisms of SARS-CoV-2 invading the central nervous system during COVID-19, and the neurological complications caused by SARS-CoV-2 infection were reviewed.

Portal Of Entry

Along with the respiratory, cardiovascular, gastrointestinal, rheumatological, and neurological manifestations of the new coronavirus infection (COVID-19), the effects of this virus on the ENT organs is undeniable, as the main portal of entry of any respiratory infection. It has been proven that symptoms such as hypo- and anosmia are associated with one of the ways of the virus penetration – transnasal, through the olfactory nerves into the central nervous system. Otorhinolaryngological complaints of patients are not limited only to deterioration or loss of smell, many note the appearance of dizziness, tinnitus, worsening of the course of chronic sensorineural hearing loss, and in some cases – sudden hearing loss, which may indicate damage to the auditory and vestibular analyzer by a viral agent. The mechanisms of development of the corresponding complications at the moment are still unclear. The presented article is a review of the literature data of foreign and domestic sources, which examines the central and peripheral neurological complications, the pathways and molecular features of the penetration of the virus, as well as clinical cases of hearing impairment and the appearance of tinnitus against the background of new coronavirus infection. At the moment, information on the direct effect of the SARS-CoV-2 virus on the auditory and vestibular analyzer is insufficient and scattered, which requires further observation with subsequent detailed analysis of the results.

The article discusses the management of patients with various neurological diseases during the COVID-19 pandemic, taking into account the determination of the level of risk of infection. The possibility of increasing the risk of infection in patients with disability, especially with impaired function of the respiratory and bulbar muscles, limited mobility, and the presence of concomitant diseases, is indicated. The recommendations on the treatment of patients with stroke, neuromuscular diseases, inflammatory and autoimmune diseases of the central nervous system, in particular, multiple sclerosis and neuromyelitis optica spectrum disorder (NMOSD), as well as non-inflammatory diseases of the central nervous system (epilepsy, Parkinson’s disease, atypical parkinsonism, dystonia, hereditary spastic paraplegia, infantile cerebral palsy, benign intracranial hypertension) are considered. Interactions of drugs for the treatment of COVID-19 and neurological diseases are given. Potential neurological complications of COVID-19 are overviewed. Potential neurological complications of COVID-19 were noted: anosmia, ageusia, viral meningitis, encephalitis, post-infectious stem encephalitis, acute necrotizing hemorrhagic leukoencephalopathy, Guillain-Barre syndrome, myositis. The importance of the fact that during the COVID-19 pandemic, when examining patients with neurological diseases, clinicians should take into account the possibility of a patient with COVID-19, and also consider it as a differential diagnosis in order to avoid diagnostic errors, prescribe timely treatment and prevent the spread of infection.

Central Nervous System Manifestations in Rheumatic DiseasesPatients with multi-system rheumatic conditions may have a disease affecting the central nervous system (CNS). Central nervous system manifestations vary according to the location of the lesion and range from focal findings (e.g., stroke-like presentations), although serious neurological complications in rheumatic disease appear to be rare. The most prominent features of neurological involvement in rheumatic diseases include cerebral ischaemia and psychiatric symptoms. Little information is available on the prevalence of neurological disease in patients with a rheumatological diagnosis. Involvement of the CNS may be a striking early or presenting feature with a wide variety of manifestations. There is more clarity about the CNS syndromes attributable to systemic lupus erythematosus and new insights into the central mechanisms involved in the manifestations of Sjögren's syndrome and rheumatoid arthritis. Severe CNS involvement is associated with poor prognosis, and high mortality rate. We review the spectrum of neurological diseases in patients with a rheumatological diagnosis.

Abstract As the coronavirus disease 2019 (COVID-19) pandemic continues to be a multidimensional threat to humanity, more evidence of neurological involvement associated with it has emerged. Neuroimmune interaction may prove to be important not only in the pathogenesis of neurological manifestations but also to prevent systemic hyperinflammation. In this review, we summarize reports of COVID-19 cases with neurological involvement, followed by discussion of possible routes of entry, immune responses against coronavirus infection in the central nervous system and mechanisms of nerve degeneration due to viral infection and immune responses. Possible mechanisms for neuroprotection and virus-associated neurological consequences are also discussed.

Coronavirus Infection

Infections of the central nervous system (CNS) infections are critical problems for public health. They are caused by several different organisms, including the respiratory coronaviruses (CoVs). CoVs usually infect the upper respiratory tract causing the common cold. However, in infants, and in elderly and immunocompromised persons, they can also affect the lower respiratory tract causing pneumonia and various syndromes of respiratory distress. CoVs also have neuroinvasive capabilities because they can spread from the respiratory tract to the CNS. Once infection begins in the CNS cells, it can cause various CNS problems such as status epilepticus, encephalitis, and long‐term neurological disease. This neuroinvasive properties of CoVs may damage the CNS as a result of misdirected host immune response, which could be associated with autoimmunity in susceptible individuals (virus‐induced neuro‐immunopathology) or associated with viral replication directly causing damage to the CNS cells (virus‐induced neuropathology). In December 2019, a new disease named COVID‐19 emerged which is caused by CoVs. The significant clinical symptoms of COVID‐19 are related to the respiratory system, but they can also affect the CNS, causing acute cerebrovascular and intracranial infections. We describe the possible invasion routes of coronavirus in this review article, and look for the most recent findings associated with the neurological complications in the recently published literature.

AbstractCurrently, SARS-CoV-2 has caused a global pandemic and threatened many lives. Although SARS-CoV-2 mainly causes respiratory diseases, growing data indicate that SARS-CoV-2 can also invade the central nervous system (CNS) and peripheral nervous system (PNS) causing multiple neurological diseases, such as encephalitis, encephalopathy, Guillain-Barré syndrome, meningitis, and skeletal muscular symptoms. Despite the increasing incidences of clinical neurological complications of SARS-CoV-2, the precise neuroinvasion mechanisms of SARS-CoV-2 have not been fully established. In this review, we primarily describe the clinical neurological complications associated with SARS-CoV-2 and discuss the potential mechanisms through which SARS-CoV-2 invades the brain based on the current evidence. Finally, we summarize the experimental models were used to study SARS-CoV-2 neuroinvasion. These data form the basis for studies on the significance of SARS-CoV-2 infection in the brain.

In December 2019, coronavirus disease (COVID-19) emerged in China and rapidly spread to the world to become the largest pandemic since the 1918 influenza. The disease has been identified as a severe acute respiratory syndrome caused by a novel coronavirus-2 (SARS-CoV-2). Although the typical presentation is respiratory symptoms, reports of neurological involvements are increasing, as more than one-third of patients with COVID-19 develop neurological manifestations. The most frequently reported neurological manifestations in COVID-19 patients were headache, dizziness, taste, and smell impairments, and altered level of consciousness. More specific neurological complications were also reported in literature including acute cerebrovascular complications, seizures, meningoencephalitis, and Guillain-Barré syndrome. Very few studies have shown CNS demyelinating lesions as complications of COVID-19. Current report described a case of a COVID-19 patient with an acute solitary demyelinating lesion in the central nervous system. I also reviewed and summarized the available related cases.

Abstract Background Presently, it is known that, even if less frequently than in adults, children can develop a severe new coronavirus disease 2019 (COVID-19). Children with the SARS-CoV-2 infection can have neurological signs and symptoms of disease more frequently than previously thought, revealing the involvement of the central nervous system, the peripheral nervous system, or both. Aim of this manuscript is to highlight the neurologic complications associated with SARS-CoV-2 among pediatric patients with COVID-19, suggesting when to monitor carefully neurologic development. Main findings Children with a severe chronic underlying disease, infants and toddlers and those who develop the so-called multisystem inflammatory syndrome (MIS-C) are those with the highest incidence of neurological complications. Fortunately, in most of the cases, neurological manifestations, mainly represented by headache and anosmia, are mild and transient and do not significantly complicate the COVID-19 course. However, in some cases, very severe clinical problems associated with relevant alterations of neuroimaging, electroencephalography, nerve conduction studies and electromyography findings can develop. Generally, almost all the children with COVID-19 and neurological manifestations till now described have made a complete recovery, although in some cases this has occurred after several weeks of treatment. Moreover, COVID-19 infection during pregnancy has been found associated with an increased risk of obstetric complications that can lead to neurological acute and long-term manifestations in neonates. Conclusions Based on data showing the neurologic impact of COVID-19 in pediatric age, we suggest monitoring neurological development a few months after healing in pediatric patients who have presented MIS-C, seizures or other neurological manifestations and in children of pregnant women with COVID-19 in order to detect overt and subtle deficits.
