Serum Vitamin D Level and Clinical Risk Factors for Benign Paroxysmal Positional Vertigo

The comorbidities identified in this study, along with the deficiency levels of 25-hydroxyvitamin D, were factors associated with BPPV in our cohort and may have contributed to the onset and recurrence of benign paroxysmal positional vertigo; thus, we suggest that prospective studies should address this possible association and, if so, treat it to accomplish an effective treatment.
