Randomized Controlled Trial Assessing Vitamin D's Role in Reducing BPPV Recurrence in Older Adults

Area of Science:

• Geriatric Medicine
• Neurology
• Nutritional Science

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness in older adults, increasing fall risk.
• The role of vitamin D in BPPV recurrence is not fully understood, necessitating further investigation.

Purpose of the Study:

• To evaluate the efficacy of vitamin D treatment in reducing BPPV recurrence rates in elderly individuals.
• To compare vitamin D supplementation against a placebo in a randomized controlled trial setting.

Main Methods:

• A single-center, double-blinded, randomized placebo-controlled trial with a 12-month follow-up.
• Participants depleted of vitamin D3 were randomized to receive vitamin D3 supplementation or placebo, alongside dietary advice.
• A control group of vitamin D3-replete participants was also monitored.

Main Results:

• The vitamin D treatment group demonstrated an 87% reduction in BPPV recurrence compared to the placebo group.
• The time to the first recurrence of BPPV was significantly longer in the vitamin D-treated group.
• No significant differences in recurrence rates or dizziness scores were observed between the vitamin D group and the replete control group.

Conclusions:

• Vitamin D supplementation shows promise in reducing BPPV recurrence in older adults, potentially lowering fall risks.
• These findings support further research into vitamin D as a potential standard of care for BPPV management.
• Reduced BPPV episodes may enhance postural stability and decrease the incidence of falls among seniors.
