Stop the spin: A practical guide to curing benign positional vertigo

Benign paroxysmal positional vertigo (BPPV) is one of the most frequent and treatable causes of dizziness, often misinterpreted as a more serious neurological issue. Characterized by brief, sudden episodes of vertigo triggered by changes in head position, BPPV stems from tiny calcium crystals (otoconia) that dislodge and float into the semicircular canals of the inner ear, disrupting normal balance signals to the brain. Although it may sound complex, BPPV is highly responsive to in-office diagnostic and repositioning maneuvers that can provide immediate relief.

Typical triggers include rolling over in bed, looking up or down, or sitting up from lying down. The Dix-Hallpike and supine roll tests are the primary tools for diagnosis, helping clinicians pinpoint the affected semicircular canal by observing specific eye movements (nystagmus) during positional changes. Once diagnosed, maneuvers like the Epley, Semont, or log roll (depending on the canal involved) guide the dislodged crystals back to their proper place, resolving the disorienting vertigo in up to 90% of cases.

Despite its simplicity, BPPV is often overlooked, leading to unnecessary testing, prolonged symptoms, and increased fall risk—especially in older adults. When correctly identified, treatment is safe, quick, and highly effective, even in primary care settings. Seasonal links to low vitamin D and conditions like migraine or osteoporosis are emerging as possible risk factors, offering new preventive avenues. Ultimately, understanding and applying these evidence-based techniques can restore balance—literally and figuratively—for countless patients.
