The most intense part of your BPPV symptoms have to do with how long it takes the crystals or sensor to settle after you move or change your head or body position. As the crystals move and settle, your brain is getting powerful false messages telling you that you are violently spinning when all you may have done is laid down or rolled over in bed.

Timothy C. Ear rocks are small crystals of calcium carbonate derived from a structure in the ear called the " utricle " figure1 on right. While the saccule also contains otoconia, they are not able to migrate into the canal system. The utricle may have been damaged by head injury, infection, or other disorder of the inner ear, or may have degenerated because of advanced age. Normal otoconia appear to have a very slow turnover, probably not fast enough to replace loss due to age or trauma.

BPPV is a mechanical problem in the inner ear. It occurs when some of the calcium carbonate crystals otoconia that are normally embedded in gel in the utricle become dislodged and migrate into one or more of the 3 fluid-filled semicircular canals, where they are not supposed to be. When enough of these particles accumulate in one of the canals they interfere with the normal fluid movement that these canals use to sense head motion, causing the inner ear to send false signals to the brain. Figure 1: Inner ear anatomy. Otoconia migrate from the utricle, most commonly settling in the posterior semicircular canal shown , or more rarely in the anterior or horizontal semicircular canals. The detached otoconia shift when the head moves, stimulating the cupula to send false signals to the brain that create a sensation of vertigo.
