A rare neurological complication of COVID-19: Pediatric Miller Fisher Syndrome. A case report

Abstract

The SARS-CoV-2 pandemic has significantly transformed the world. While it was initially viewed as a respiratory virus, it has now been found to cause cardiovascular, gastrointestinal, and psychological complications. Moreover, the nervous system (NS) is also greatly affected. Research has identified dizziness, headaches, as well as disturbances in one's taste and smell abilities as the most frequent symptoms of NS involvement. Even more significant changes may occur in patients who get infected with SARS CoV-2, such as the development of acute cerebrovascular disorders (stroke), multiple sclerosis, acute disseminated encephalitis, Guillain-Barré syndrome, encephalitis, and myelitis. It is important to note these potential complications and monitor patients closely. A retrospective study conducted in Wuhan, China revealed that CNS (central nervous system) involvement occurred three times more frequently than PNS (peripheral nervous system) involvement. This emphasizes the critical importance of studying and describing CNS manifestations. This case report depicts Miller Fisher syndrome in a 5-month-old infant after SARS CoV-2 infection and explores literature on pediatric cases and potential pathogenic mechanisms.
