So what triggered the leap from hearing loss to incapacitating dizziness in Miller's case? The etiology is unknown, Miller says, pointing to the possibility of a virus or inner-ear inflammation. Tumors are another cause, says Nevin, along with specific conditions such as Meniere's disease or benign paroxysmal positional vertigo, the latter of which is the most common. In BPPV, which is diagnosed with a simple clinical test, particles in the inner ear dislodge and cause the spinning sensation when one rolls over in bed or bends. I can't remove the particles, but I can help them go back in place, says Nevin.
