The
most common cause of vertigo caused by the inner ear is a disease called Benign
Paroxysmal Positional Vertigo (BPPV) or Benign Paroxysmal Vertigo (BPV)
The ear normally uses small crystals called “otoconia” to determine
the direction of gravity. In a disease state these crystals come loose and float
around inside the inner ear. These crystal particles cause the sensation of vertigo
(spinning) every time they are disturbed by head motion.
