reported were stroke, GBS, ADEM and encephalitis. A rare case of sensory motor polyneuropathy (SMPN) in COVID 19 was reported
in our institute.
Methods: A COVID19 diseased patient without any previous neurological disorders was admitted and during the course of treatment
developed neurological complications. After complete radiological and pathological evaluation he was diagnosed as a case of SMPN
- a new manifestation of SARS - CoV2 infection.
Results: HRCT chest shows COVID 19 related ARDS, MRI (T2W) at D6-10 spines shows subtle patchy intramedullary high signal
intensity and Nerve conduction study revealed asymmetrical sensory-motor polyneuropathy. He had leucocytosis with neutrophilia,
lymphopenia, raised Neutrophil-lymphocyte ratio, D-Dimer and ferritin.
Conclusion: SMPN is relatively rare but acute manifestation of SARS-CoV2 infection which need immediate management and long
term follow up to diagnose chronic complication related with it.

one-third of patients with SARS-CoV-2 develop neurological mani-
festations [1]. The pathological spectrum of the disease include
encephalitis, plexitis, radiculitis, encephalopathy, ischemic stroke,
GBS, Multiple sclerosis, transverse myelitis and sensory-motor
polyneuropathy. SARS-CoV-2 attacks the olfactory bulb and then
affect the CNS through the olfactory tract in the early stages of in-
fection [2]. Neurological impairment and demyelinating reaction
appear as complications in case of severe COVID-19 [1].
Neurotropism may occur via trans-lamina cribrosa to reach the
brain through the olfactory tract [3]. The SARS -CoV2 spike pro-
tein binds with host ACE 2receptor, expressed in the CNS capillary
endothelium and allows the virus to penetrate the neuronal cells
[4]. Budding of Virus particle lead to the onset of symptoms such
as anosmia and dysguesia in the early phase of infection [1]. The

the diagnosis of GBS. The recent studies had described less than
30 cases to date of GBS as CNS manifestation of COVID 19 disease;
however, the pathophysiology of the same is still not clear.
ADEM is a syndrome of multifocal demyelination, developing
weeks after an infection, presents generally with focal neurologi-
cal symptoms and often with encephalopathy. There are two cases
of ADEM reported to date. One have progressive dysphagia, dysar-
thria, and encephalopathy nine days after the onset of headache
and myalgia [7]. The other presented with seizures and reduced
consciousness and required intubation for respiratory failure [8].
Both patients had normal CSF and high signal intensities on MRI,
typical of acute disseminated encephalomyelitis. Both of them
show clinical improvement after treatment with IV Ig and steroids
respectively. Symptoms of our case resemble very similar to this;
hence we cannot exclude the possibility of the same.
In investigating patients with limb weakness and sensory
change, it is crucial to distinguish between the disease of the pe-

[9]. CSF examination, neurophysiological studies, and spinal imag-
ing are essential.
Conclusion
CNS manifestations in SARS - CoV2 infection is probably the re-
sult of direct cytolytic activity of virus itself or the indirect effect
of altered hemodynamic milieu secondary to cytokine storm that
result in acute CNS disorders, some of which are entirely reversible
whereas few of them may progress gradually in a dormant form
and reappear in future. Possibilities of psychomotor dysfunction
cannot be ruled out. Hence it will be suggested that these patients
must be followed up for several years at frequent intervals to as-
sess the long term effect of the virus.
Key Messages
Sensory motor polyneuropathy is an immediate COVID 19 asso-
ciated complication which will be completely reversible provided
diagnosed and treated as early as possible.

Importance The outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, is serious and has the potential to become an epidemic worldwide. Several studies have described typical clinical manifestations including fever, cough, diarrhea, and fatigue. However, to our knowledge, it has not been reported that patients with COVID-19 had any neurologic manifestations. Objective To study the neurologic manifestations of patients with COVID-19. Design, Setting, and Participants This is a retrospective, observational case series. Data were collected from January 16, 2020, to February 19, 2020, at 3 designated special care centers for COVID-19 (Main District, West Branch, and Tumor Center) of the Union Hospital of Huazhong University of Science and Technology in Wuhan, China. The study included 214 consecutive hospitalized patients with laboratory-confirmed diagnosis of severe acute respiratory syndrome coronavirus 2 infection. Main Outcomes and Measures Clinical data were extracted from electronic medical records, and data of all neurologic symptoms were checked by 2 trained neurologists. Neurologic manifestations fell into 3 categories: central nervous system manifestations (dizziness, headache, impaired consciousness, acute cerebrovascular disease, ataxia, and seizure), peripheral nervous system manifestations (taste impairment, smell impairment, vision impairment, and nerve pain), and skeletal muscular injury manifestations. Results Of 214 patients (mean [SD] age, 52.7 [15.5] years; 87 men [40.7%]) with COVID-19, 126 patients (58.9%) had nonsevere infection and 88 patients (41.1%) had severe infection according to their respiratory status. Overall, 78 patients (36.4%) had neurologic manifestations. Compared with patients with nonsevere infection, patients with severe infection were older, had more underlying disorders, especially hypertension, and showed fewer typical symptoms of COVID-19, such as fever and cough. Patients with more severe infection had neurologic manifestations, such as acute cerebrovascular diseases (5 [5.7%] vs 1 [0.8%]), impaired consciousness (13 [14.8%] vs 3 [2.4%]), and skeletal muscle injury (17 [19.3%] vs 6 [4.8%]). Conclusions and Relevance Patients with COVID-19 commonly have neurologic manifestations. During the epidemic period of COVID-19, when seeing patients with neurologic manifestations, clinicians should suspect severe acute respiratory syndrome coronavirus 2 infection as a differential diagnosis to avoid delayed diagnosis or misdiagnosis and lose the chance to treat and prevent further transmission.

Structure of the nCoV trimeric spike The World Health Organization has declared the outbreak of a novel coronavirus (2019-nCoV) to be a public health emergency of international concern. The virus binds to host cells through its trimeric spike glycoprotein, making this protein a key target for potential therapies and diagnostics. Wrapp et al. determined a 3.5-angstrom-resolution structure of the 2019-nCoV trimeric spike protein by cryo–electron microscopy. Using biophysical assays, the authors show that this protein binds at least 10 times more tightly than the corresponding spike protein of severe acute respiratory syndrome (SARS)–CoV to their common host cell receptor. They also tested three antibodies known to bind to the SARS-CoV spike protein but did not detect binding to the 2019-nCoV spike protein. These studies provide valuable information to guide the development of medical counter-measures for 2019-nCoV. Science , this issue p. 1260

Respiratory viruses infect the human upper respiratory tract, mostly causing mild diseases. However, in vulnerable populations, such as newborns, infants, the elderly and immune-compromised individuals, these opportunistic pathogens can also affect the lower respiratory tract, causing a more severe disease (e.g., pneumonia). Respiratory viruses can also exacerbate asthma and lead to various types of respiratory distress syndromes. Furthermore, as they can adapt fast and cross the species barrier, some of these pathogens, like influenza A and SARS-CoV, have occasionally caused epidemics or pandemics, and were associated with more serious clinical diseases and even mortality. For a few decades now, data reported in the scientific literature has also demonstrated that several respiratory viruses have neuroinvasive capacities, since they can spread from the respiratory tract to the central nervous system (CNS). Viruses infecting human CNS cells could then cause different types of encephalopathy, including encephalitis, and long-term neurological diseases. Like other well-recognized neuroinvasive human viruses, respiratory viruses may damage the CNS as a result of misdirected host immune responses that could be associated with autoimmunity in susceptible individuals (virus-induced neuro-immunopathology) and/or viral replication, which directly causes damage to CNS cells (virus-induced neuropathology). The etiological agent of several neurological disorders remains unidentified. Opportunistic human respiratory pathogens could be associated with the triggering or the exacerbation of these disorders whose etiology remains poorly understood. Herein, we present a global portrait of some of the most prevalent or emerging human respiratory viruses that have been associated with possible pathogenic processes in CNS infection, with a special emphasis on human coronaviruses.

The recent outbreak of coronavirus infectious disease 2019 (COVID-19) has gripped the world with apprehension and has evoked a scare of epic proportion regarding its potential to spread and infect humans worldwide. As we are in the midst of an ongoing pandemic of COVID-19, scientists are struggling to understand how it resembles and differs from the severe acute respiratory syndrome coronavirus (SARS-CoV) at the genomic and transcriptomic level. In a short time following the outbreak, it has been shown that, similar to SARS-CoV, COVID-19 virus exploits the angiotensin-converting enzyme 2 (ACE2) receptor to gain entry inside the cells. This finding raises the curiosity of investigating the expression of ACE2 in neurological tissue and determining the possible contribution of neurological tissue damage to the morbidity and mortality caused by COIVD-19. Here, we investigate the density of the expression levels of ACE2 in the CNS, the host–virus interaction and relate it to the pathogenesis and complications seen in the recent cases resulting from the COVID-19 outbreak. Also, we debate the need for a model for staging COVID-19 based on neurological tissue involvement.

Acute disseminated encephalomyelitis (ADEM) is a rare idiopathic inflammatory demyelinating disease of the central nervous system (CNS), which usually occurs following a viral or bacterial infection, or vaccination. Characteristically, ADEM presents with acute encephalopathy with accompanying multifocal neurological symptoms and signs. Due to unavailability of a specific biological marker, neuroimaging is very important in establishing the diagnosis of ADEM. The typical magnetic resonance imaging findings of ADEM are large, multiple and almost symmetrical white matter lesions. Herein, we report a 31-year-old woman presenting with headache, confusion, left hemiparesis and hemihypoesthesia preceded by an infection. The patient fully recovered after intravenous methylprednisolone treatment. MRI revealed white-matter lesions that were typical for ADEM, but the unihemispheric involvment broadened the spectrum of disseminated encephalomyelitis. (Archives of Neuropsychiatry 2010; 47: 166-8)
