Loss of Taste as an Initial Symptom of a ?Facial Diplegia and Paresthesia? Variant of Guillain-Barr? Syndrome

Loss of taste is a relatively common symptom of coronavirus disease 2019 (COVID-19) and has also been considered a rare Guillain-Barre syndrome (GBS) symptom. We herein report a case of a facial diplegia and paresthesia (FDP) variant of GBS that initially presented as a loss of taste occurring two weeks after COVID-19 mRNA vaccination. The patient recovered completely after intravenous immunoglobulin therapy. Clini-cians should consider the possibility of post-vaccination FDP manifesting as facial palsy and should be aware that GBS, including the FDP variant, can initially present as an isolated loss of taste.

Automated summary

Loss of taste can be a symptom of Guillain-Barre syndrome (GBS) after COVID-19 vaccination. Clinicians should be aware of this possibility and provide timely treatment.
