BPPV is a mechanical disorder which occurs as a result of the displacement of tiny crystals of calcium carbonate‚ also called otoconia. Typically‚ otoconia reside in the otolith organs and play a crucial role in detecting head movement. When the crystals get displaced‚ often due to trauma‚ they collect in one of the semicircular canals and cause vertigo symptoms. When the head is still‚ the otoconia settle within the semicircular canals and there are no vertigo symptoms. When the head is rapidly
