Anti-NMDA receptor (NMDAR) encephalitis is characterized by mood and behavior changes, seizures, abnormal movements, autonomic instability, and encephalopathy. It occurs most commonly in young adults. A paraneoplastic association has been made with ovarian teratoma, though this is rare in children1. More recently, cases of anti-NMDAR encephalitis following viral infections have been reported, including herpes simplex virus (HSV), Japanese encephalitis virus (JEV), and now the 2019 novel coronavirus (SARS-CoV-2)2-5.
AbstractObjectivesEvidences from either small series or spontaneous reporting are accumulating that SARS-CoV-2 involves the Nervous Systems. The aim of this study is to provide an extensive overview on the major neurological complications in a large cohort of COVID-19 patients.MethodsRetrospective, observational analysis on all COVID-19 patients admitted from February 23rd to April 30th, 2020 to ASST Papa Giovanni XXIII, Bergamo, Italy for whom a neurological consultation/neurophysiological assessment/neuroradiologic investigation was requested. Each identified neurologic complication was then classified into main neurolog...
CONCLUSION: According to the Centers for Disease Control, common symptoms of human coronavirus include fever, cough, runny nose, sore throat, and headache. In the case of SARS-CoV-2, there are limited reports about headaches, one of the most common clinical manifestations. There are currently no studies that focus specifically on headache among patients with SARS-CoV-2 infection. PMID: 33017479 [PubMed - as supplied by publisher]
Conclusions High-titer anti-SARS-CoV-2 antibodies were detected in the CSF of comatose or encephalopathic patients demonstrating intrathecal IgG synthesis or BBB disruption. A disrupted BBB may facilitate the entry of cytokines and inflammatory mediators into the CNS enhancing neuroinflammation and neurodegeneration. The observations highlight the need for prospective CSF studies to determine the pathogenic role of anti–SARS-CoV-2 antibodies and identify early therapeutic interventions.

We report a 20-year-old female with SARS-CoV-2 encephalitis who presented with 4 days of upper respiratory symptoms, fevers and sudden acute altered mental status. An extensive work up led to the most likely cause for the neurologic decompensation to be viewed as SARS-CoV-2 symptomology.
AbstractRespiratory viruses are opportunistic pathogens that infect the upper respiratory tract in humans and cause severe illnesses, especially in vulnerable populations. Some viruses have neuroinvasive properties and activate the immune response in the brain. These immune events may be neuroprotective or they may cause long-term damage similar to what is seen in some neurodegenerative diseases. The new “Severe Acute Respiratory Syndrome Coronavirus 2” (SARS-CoV-2) is one of the Respiratory viruses causing highly acute lethal pneumonia coronavirus disease 2019 (COVID-19) with clinical similarities to those rep...
Conclusion: We believe this is the first case involving neural system injury in a patient who confirmed COVID-19 based on CSF antibody test results. Negative ribonucleic acid test results, strong positivity for antibodies, and high protein levels in the CSF suggest the possibility of autoimmune encephalitis secondary to COVID-19. This case highlights additional novel symptoms of COVID-19, and these data are important for the assessment and follow-up of COVID-19 patients.
Mitkumar Dharsandiya, Kinjal Shah, Ketan Patel, Tushar Patel, Amrish Patel, Atul PatelIndian Journal of Medical Microbiology 2020 38(2):219-221 SARS-CoV-2 predominantly involves the lungs producing acute lung injury, but it can also give rise to a variety of complications involving the central nervous system, gastrointestinal system, kidney and also viral sepsis. With this case report, we are discussing unusual series of complication from acute lung injury, followed by viral sepsis then encephalitis, followed by progressive macrophage activation syndrome.
The SARS-CoV-2 pandemic originated in China has caused a severe impact on worldwide health. Respiratory symptoms accompanied by unspecific systemic complaints are the most common presentation. However, neurological symptoms and complications could be found in a patient, and this might confer a poor prognosis. In this view, we aim to present a narrative review of neurological manifestations and complications of SARS-CoV-2 infection by performing literature research. We found nonspecific neurological symptoms such as headache, lethargy, anosmia, and dysgeusia reported in a few cohorts. Case reports of encephalitis, acute nec...
