COVID-19 is an urgent problem all over the world that affects not only the respiratory system, but also causes many neurological disorders. In connection with the clinical manifestations of COVID-19, further detailed study of neurological complications is required, such as ischemic and hemorrhagic strokes, damage to the peripheral nervous system, and inflammatory diseases of the brain. Some neurological symptoms after an illness may persist for several weeks or even months. Hemorrhagic encephalitis is one such complication of COVID-19. Taking into account the growth of COVID-19 and frequent neurological complications after a previous illness, more and more often patients will seek medical help from a specialist, such as a neurologist, psychologist, psychiatrist. The only protection against COVID-19, which causes serious complications, is vaccination. The purpose of the study was to highlight a rare case of hemorrhagic encephalitis, which developed against the background of the previous COVID-19 disease. Materials and methods. The work is based on a description of a clinical case of hemorrhagic encephalitis in a patient who has undergone COVID-19. The modern literature data on the clinical and diagnostic features and therapeutic possibilities of hemorrhagic encephalitis are presented. Results and discussion. The article examines data on the clinical manifestations of COVID-19, which can occur in both mild and severe forms, reflects the diagnostic criteria of this disease, highlights treatment approaches, discusses in detail and provides data on the main aspects of the pathogenetic mechanisms underlying development of the disease. Complications of COVID-19 have been described, not only from the central and peripheral nervous system, but also from other systems. The second part of the article is presented in the form of a clinical case of hemorrhagic encephalitis against the background of the undergone COVID-19, which was recorded in our hospital. This part of the article describes in detail the patient's complaints and anamnestic data, the data of the somatic and neurological examination at the time of admission to the hospital and in dynamics, and describes the treatment tactics. Attention is especially focused on the cognitive functions of this patient, which will become the reason for seeing a psychiatrist in the future. Conclusion. Neurological complications of COVID-19 are increasingly registered, requiring close attention from neurologists. Hemorrhagic encephalitis can be one of these complications

The novel coronavirus disease 2019 (COVID-19) is a global pandemic. Although the main clinical manifestations of the COVID-19 infection have confined to the respiratory system, there is some evidence suggesting the neuro-invasive potential of the COVID-19. There are limited reports of Guillain–Barré syndrome (GBS) as a peripheral nervous system complication of COVID-19 infection. We described four patients with COVID-19 infection who developed acute polyneuropathy with a final diagnosis of Guillain–Barré syndrome. COVID-19 may have the potential to invade the peripheral nervous system. GBS, as one of the critical neurological complications of COVID-19, could be considered as a post-infectious event.

AbstractCoronavirus disease 2019 (COVID-19) is a potentially severe acute respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This outbreak, which emerged in Wuhan city, rapidly spread throughout China and has now become a global public health concern. SARS-CoV-2 is a highly pathogenic and transmissible virus. Common clinical manifestations of COVID-19 include fever, dry cough, shortness of breath, muscle ache, headache, and confusion. Currently, there is no confirmed effective therapeutic strategy for COVID-19 because the pathological mechanism is poorly understood. In addition to the respiratory system involvement, recent evidence has shown that SARS-CoV-2 can affect other organ systems including nervous, vascular, digestive, and urinary system. Various neurological complications have also been described in various studies. Nervous system involvement in the case of SARS-CoV-2 is explained by direct neuro invasion, immune mechanism, and other systemic factors. Neurological complications due to SARS-CoV-2 include both central and peripheral nervous system involvement. Central nervous system complications range from mild headache to seizures, encephalitis, myelitis, and acute cerebrovascular accidents. Peripheral nervous system complications range from vague muscle pains to Guillain–Barré syndrome. This article briefly discusses the various neurological and mental health issues related to COVID-19.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

In clinical practice, a sufficiently large number of patients complain of neurological disorders caused by osteochondrosis of the cervical spine. Despite this, in some cases, the development and progression of this symptomatology may be due to an anomaly in the structure of the cervical spine (Klippel-Feil syndrome), which is genetically determined. Timely diagnosis of this pathology with the implementation of complex research methods allows you to develop individual tactics for each individual patient, taking into account the severity of clinical manifestations to slow the progression of complications.

Objective. Some viral infections can have a harmful effect on the functioning of the nervous system and can even cause serious neurological damage. This work aims to review the results of studies published so far concerning neurological complications in people infected with coronaviruses, especially SARS-CoV-2, and possible mechanisms responsible for nervous system damage. Literature review. Recently, there have been reports that coronaviruses, including SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), cause acute respiratory disease, exhibit neurotropic properties and can also cause neurological symptoms. There are studies published showing that these viruses may penetrate to the brain and cerebrospinal fluid. Conclusions. Coronaviruses are still poorly understood, so it seems important to study the potential impact of SARS-CoV-2 infections on the nervous system. It seems appropriate that patients infected with SARS-CoV-2 should be early evaluated for neurological symptoms, including headache and impaired consciousness.

Abstract Background: SARS-CoV-2 can affect the human brain and other neurological structures. An increasing number of publications report neurological manifestations in patients with COVID-19. However, no studies have comprehensively reviewed the clinical and paraclinical characteristics of the central and peripheral nervous system's involvement in these patients. This study aimed to describe the features of the central and peripheral nervous system involvement by COVID-19 in terms of pathophysiology, clinical manifestations, neuropathology, neuroimaging, electrophysiology, and cerebrospinal fluid findings.Methods: We conducted a comprehensive systematic review of all the original studies reporting patients with neurological involvement by COVID-19, from December 2019 to June 2020, without language restriction. We excluded studies with animal subjects, studies not related to the nervous system, and opinion articles. Data analysis combined descriptive measures, frequency measures, central tendency measures, and dispersion measures for all studies reporting neurological conditions and abnormal ancillary tests in patients with confirmed COVID-19.Results: A total of 143 observational and descriptive studies reported central and peripheral nervous system involvement by COVID-19 in 10723 patients. Fifty-one studies described pathophysiologic mechanisms of neurological involvement by COVID-19, 119 focused on clinical manifestations, 4 described neuropathology findings, 62 described neuroimaging findings, 28 electrophysiology findings, and 60 studies reported cerebrospinal fluid results. The reviewed studies reflect a significant prevalence of the nervous system's involvement in patients with COVID-19, ranging from 22.5% to 36.4% among different studies, without mortality rates explicitly associated with neurological involvement by SARS-COV-2. We thoroughly describe the clinical and paraclinical characteristics of neurological involvement in these patients. Conclusions: Our evidence synthesis led to a categorical analysis of the central and peripheral involvement by COVID-19 and provided a comprehensive explanation of the reported pathophysiological mechanisms by which SARS-CoV-2 infection may cause neurological impairment. International collaborative efforts and exhaustive neurological registries will enhance the translational knowledge of COVID-19's CNS and PNS involvement and generate strategies for therapeutic decision-making.Registration: This review is registered in PROSPERO (CRD42020193140), July 24, 2020.

Noradrenergic Differentiation

Mash1, a mammalian homologue of the Drosophila proneural genes of the achaete-scute complex, is transiently expressed throughout the developing peripheral autonomic nervous system and in subsets of cells in the neural tube. In the mouse, targeted mutation of Mash1 has revealed a role in the development of parts of the autonomic nervous system and of olfactory neurons, but no discernible phenotype in the brain has been reported. Here, we show that the adrenergic and noradrenergic centres of the brain are missing in Mash1 mutant embryos, whereas most other brainstem nuclei are preserved. Indeed, the present data together with the previous results show that, except in cranial sensory ganglia, Mash1 function is essential for the development of all central and peripheral neurons that express noradrenergic traits transiently or permanently. In particular, we show that, in the absence of MASH1, these neurons fail to initiate expression of the noradrenaline biosynthetic enzyme dopamine beta-hydroxylase. We had previously shown that all these neurons normally express the homeodomain transcription factor Phox2a, a positive regulator of the dopamine beta-hydroxylase gene and that a subset of them depend on it for their survival. We now report that expression of Phox2a is abolished or massively altered in the Mash1−/− mutants, both in the noradrenergic centres of the brain and in peripheral autonomic ganglia. These results suggest that MASH1 controls noradrenergic differentiation at least in part by controlling expression of Phox2a and point to fundamental homologies in the genetic circuits that determine the noradrenergic phenotype in the central and peripheral nervous system.
