The sudden vestibular abnormalities among people with the COVID-19 infection or improved people of the COVID-19: a literature review

The aim of this review study was to overview articles available from 2019 to 2021 to answer the question: "Is the COVID-19 associated with sudden vestibular abnormalities among people with COVID-19 infection or improved peopleof the COVID-19?" Articles included in this review were searched through the PubMed, Scopus, and Google Scholar databases from 2019 to 2021. We have utilized the search terms vertigo, dizziness, vestibular neuritis, and C0VID-19. According to the 33 available articles, the total number of patients was 363. The 95 patients (26.1%) reported dizziness, vertigo, and imbalance during the COVID-19 infection or after of the recovery. The 12 patients (12.6%) showed the vestibular neuritis, 2 patients (2.1%) indicated the cerebellitis, 2 patients (2.1%) demonstrated the benign paroxysmal positional vertigo, 2 patients observed (about 1%) with the labyrinthitis, and 1 patient (about 1%) depicted the intra-labyrinthine hemorrhage. Several studies have been reported the relationship between the COVID-19 and the vestibular system. Although more comprehensive studies are needed to investigate this matter but the evidence suggests that the COVID-19 is a neuroinvasive virus, and it is the most likely hypothesis for the cause of sudden vestibular abnormalities in the infected patients.
