BPPV is a disease that affects the inner ear’s vestibular system causing vertigo along with other adverse symptoms. Vertigo is the sensation of the surrounding environment being whirled during normal movements. The vestibular organs, which include the utricle, saccule, and 3 semicircular canals, are located in the innermost part of the ear. Crystals of calcium are present in the utricle,  aiding the ability to sense motion. These crystals can occasionally fall into one of the fluid-filled semicircular canals. If the crystals are moving, the canals can send incorrect balance signals to the brain causing many disorienting symptoms.
