Vitamin D Insufficiency/Deficiency in Patients with Recurrent Benign Paroxysmal Positional Vertigo

Area of Science:

• Neurology
• Endocrinology

Background:

• Hypovitaminosis D, or vitamin D deficiency, is a growing concern.
• Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder.

Purpose of the Study:

• To investigate the association between vitamin D levels and BPPV.
• To determine if vitamin D supplementation impacts BPPV relapse rates.
• To assess if correcting vitamin D deficiency improves BPPV treatment outcomes.

Main Methods:

• A cohort of 26 BPPV patients and 24 controls were analyzed.
• Serum 25(OH) vitamin D levels were measured in all participants.
• BPPV patients received physical therapy and, if deficient, vitamin D (cholecalciferol) supplementation.

Main Results:

• A significant relationship was found between vitamin D deficiency and BPPV onset.
• Correction of hypovitaminosis D led to a reduction in BPPV relapses.
• Fewer patients experienced recurrent BPPV after vitamin D supplementation.

Conclusions:

• Vitamin D deficiency is associated with the occurrence of BPPV.
• Supplementation helps reduce BPPV recurrence.
• Vitamin D supplementation did not significantly alter BPPV response to physical therapy.
