Background In December 2019, unexplained cases of pneumonia emerged in Wuhan, China, which were found to be secondary to the novel coronavirus SARS-CoV-2. On March 11, 2020, the WHO declared the Coronavirus Disease 2019 (COVID-2019) outbreak, a pandemic. Objective To clarify the neurological complications of SARS-CoV-2 infection including the potential mechanisms and therapeutic options. Methods We conducted a systematic literature search from December 01, 2019 to May 14, 2020 using multiple combinations of keywords from PubMed and Ovid Medline databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included articles with cases of COVID-19 where neurological involvement was evident. Results We were able to identify 82 cases of COVID-19 with neurological complications. The mean age was 62.3 years. 37.8% of the patients were women (n = 31). 48.8% of the patients (n = 40) had cerebrovascular insults, 28% (n = 23) had neuromuscular disorders, and 23% of the patients (n = 19) had encephalitis or encephalopathy. Conclusions Neurological manifestations of COVID-19 are not rare, especially large vessel stroke, Guillain-Barre syndrome, and meningoencephalitis. Moving forward, further studies are needed to clarify the prevalence of the neurological complications of SARS-CoV-2 infection, investigate their biological backgrounds, and test treatment options. Physicians should be cautious not to overlook other neurological diagnoses that can mimic COVID-19 during the pandemic.
Background: In December 2019, unexplained cases of pneumonia emerged in Wuhan, China, which were found to be secondary to the novel coronavirus SARS-CoV-2. On March 11, 2020, the WHO declared the Coronavirus Disease 2019 (COVID-2019) outbreak, a pandemic. Although the most common presentations of COVID-19 are fever, cough and shortness of breath, several clinical observations indicate that COVID-19 does affect the central and peripheral nervous system. Methods: We conducted a systematic literature search from December 01, 2019 to May 14, 2020 using multiple combinations of keywords from PubMed and Ovid Medline databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included articles with cases of COVID-19 that were evident for neurological involvement. Results: We were able to identify 82 cases of COVID-19 with neurological complications. The mean age was 62.28 years. 37.8% of the patients were women (n = 31). 48.8% of the patients (n=40) had cerebrovascular insults, 28% (n=23) had neuromuscular disorders, 18.3% of the patients (n=15) had encephalitis or encephalopathy, and 2.4% (n=2) presented with status epilepticus. Conclusions: Neurological manifestations of COVID-19 infection are not rare, especially large vessel stroke, Guillain barre syndrome and meningoencephalitis. Moving forward, further studies are needed to clarify the prevalence of the neurological complications of COVID-19, investigate their biological backgrounds, and test treatment options. Physicians should be cautious not to overlook other neurological diagnoses that can mimic COVID-19 during the pandemic.
Infection from SARS-CoV-2 virus has developed into a worldwide pandemic. Potential neurological complications include meningitis, encephalitis, Guillain-Barre syndrome, cerebrovascular disease, seizures, and demyelinating disease. In this paper, we describe a case of newly diagnosed multiple sclerosis co-occurring with active COVID-19 infection.
Background Idiopathic intracranial hypertension, also known as pseudotumor cerebri, is a disorder characterized by increased intracranial pressure of unclear pathogenesis in the absence of other structural and obstructive lesions that is predominantly, although not exclusively, seen in obese women of childbearing age. Patients with idiopathic intracranial hypertension commonly present with a headache, transient visual obscurations, and intracranial noises with some cranial nerves occasionally involved, most commonly CN VI. We report idiopathic intracranial hypertension presenting with isolated complete unilateral facial nerve palsy, as the sole cranial nerve involved, which is a presentation rarely reported in the literature. Case presentation A 40-year-old Hispanic woman with a history of obesity and hypertension presented to our emergency department complaining of bifrontal headache for 3 days associated with nausea, vomiting, transient visual disturbances, and a picture of right-sided cranial nerve VII palsy. Her neurologic examination including other cranial nerves was otherwise normal, but a fundus examination revealed bilateral grade II papilledema. Imaging studies ruled out structural and obstructive lesions as possible causes of her symptoms and lumber puncture results were unremarkable except for an increased opening pressure. She was then started on prednisone and acetazolamide. Two days later, she reported a dramatic improvement in both headache and facial nerve palsy. Conclusions Idiopathic intracranial hypertension should be suspected in obese young women presenting with headache and transient visual complaints and some cranial nerve abnormalities. Idiopathic intracranial hypertension is a diagnosis of exclusion and imaging studies should always be performed to rule out other structural and obstructive lesions. In this case report, we aimed to draw attention to the possibility of idiopathic intracranial hypertension presenting with unilateral cranial nerve VII palsy as the only cranial nerve involved, which needs a high index of suspicion by clinicians. The mechanisms of cranial nerve VII palsy in idiopathic intracranial hypertension are not well understood and prompt further investigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
