In the recent pandemic disease, called COVID-19, the role of neurologists and neurobiologists represents a chance to study key features of brain infection and deepen neurological manifestations of COVID-19 and other coronavirus infections. In fact, many studies suggest brain damage during infection and persistent neurological symptoms after COVID-19 infection. Reverse transcription PCR test, antibody tests, Magnetic Resonance of lung, and Computed Tomography of brain of the patient were periodically performed during this case report for eight months after infection. The aim of this article is to describe the prolonged neurological clinical consequences related to COVID-19. We believe it is clinically clear that we can define a post-acute COVID-19 neurological syndrome. Therefore, in patients after a severe clinical condition of COVID-19, a deepening of persistent neurological signs is necessary.
In December 2019, in Wuhan (China), a highly pathogenic coronavirus, named SARS-CoV-2, dramatically emerged. This new virus, which causes severe pneumonia, is rapidly spreading around the world, hence it provoked the COVID-19 pandemic. This emergency launched by SARS-CoV-2 also had, and still has, devastating socio-economic aspects. Assessing the impact of COVID-19 on vulnerable groups of people is crucial for the adaptation of governments’ responses. Growing scientific evidence suggests that it is essential to keep the attention on people after acute SARS-CoV-2 infection; indeed, some clinical manifestations are frequently present even after recovery. There is consensus on the need to define which symptoms persist after the infection and which disabilities may arise after COVID-19. Recent reviews, case reports, and original contributions suggest that various organs may be affected, and neurological symptoms are present in about one third of patients with COVID-19. Neurological complications after severe COVID-19 infection might include delirium, brain inflammation, stroke, and nerve damage. In the recent pandemic, neurologists and neurobiologists have a chance to study key features of infection neurology. Furthermore, the psychological impact of the pandemic should not be underestimated, although there is currently no definition for this condition.
Background The COVID-19 pandemic, induced by the worldwide spreading of the SARS-CoV-2, is well known for its clinical picture consistent with respiratory symptoms. If pulmonary complications are the most common manifestation of the disease, neurological problems are also significantly present, with complications including acute cerebrovascular events, encephalitis, Guillain-Barré and Miller Fisher syndromes, acute necrotizing hemorrhagic encephalopathy and hemophagocytic lymphohistiocytosis. These medical signs can be considered direct effects of the virus on the nervous system, para-infectious or post-infectious immune-mediated diseases, and neurological complications of the systemic effects of the SARS-CoV-2. Case In the present article, the encephalitis case in a 5-year-old girl positive for COVID-19 admitted to the emergency department complaining of fever and swelling in the neck is described. At this time, her neurological examination was unremarkable. Over the next few days, the fever went down and she experienced acute behavioral changes, mild confusion, and drowsiness. The brain MRI and electroencephalography (EEG) showed CNS involvement, suggestive of encephalitis. Conclusion The dramatic improvement of the symptoms after immunotherapy with corticosteroids reinforced the hypothesis of an immune-related mechanism.
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.
