The Human Barometer

There has long been a question about what causes BPPV, or vertigo caused by “loose crystals” in the ear. Personally, I will often get an influx of new patients with vertigo at the change in seasons and/ or with certain weather patterns. There was a recent research article: “Barometric pressure and the incidence of benign paroxysmal positional vertigo” that was released in American Journal of Otolaryngology this May that finally confirmed the correlation. The article found that where every one-unit increase in barometric pressure there is an expected increase of 6.1 diagnoses. It’s nice that they finally have the research to match what therapists and patients have been feeling for years!
