BPPV occurs when someone experiences dizziness while their head is in a certain position.
It is most common in older people, but can also occur after whiplash inuries, concussion, sports injuries, and some antibiotic medications.
CAUSE: BBPV is caused by crystals (otoconia) floating in the semicircular canals of the ears that increase the densitivity of the canal to velocity, and sends conflicting sensory input into the brain.
SIGNS and SYMPTOMS: include vertigo, nystagmus and unsteadiness
TREATMENT: Diagnostic tests are performed to determine which of the 6 semicircular canals is affected. This is then followed by a procedure that helps to flush the crystals out of the affected semicircular canal. The procedure is taught to the patient who can then continue with the treatment at home. The most commonly known procedures are the Hlll-Pike-Dix and the Epley maneuvers.
