COVID-19 Induced Miller Fisher Syndrome Presenting With Autonomic Dysfunction: A Unique Case Report and Review of Literature.

ABSTRACT

A plethora of neurological manifestations are associated with the 2019 coronavirus infectious disease (COVID-19). We hereby report the first case of a patient infected with SARS-CoV-2 who acutely presented with autonomic dysfunction preceding the onset of complete clinical picture of Miller Fisher syndrome. She was finally diagnosed to be a case of anti-ganglioside antibody positive post-COVID-19 Miller Fisher syndrome with dysautonomia and treated with intravenous immunoglobulin with an excellent response. We also discuss the plausible pathogenic mechanisms of COVID-19 induced Miller Fisher syndrome and furnish a review of the post-COVID-19 Miller Fisher syndrome cases reported.
