Moreover, Hashimoto’s thyroiditis (HT) has been found to be closely linked to BPPV recurrence, with correlation analyses yielding significant results (p < 0.0001) (67) Elevated serum levels of thyroid peroxidase antibody (TPO-Ab; p = 0.0117) and thyroglobulin antibody (TG-Ab; p = 0.0025) further confirmed the link between autoimmune thyroid responses and BPPV recurrence (67). Here, TG is linked to thyroiditis.
