The most common form of vertigo is best treated with the easiest and quickest method, according to a new practice parameter issued on May 26 by the American Academy of Neurology.
Posterior canal benign paroxysmal positional vertigo (BPPV) accounts for up to 30% of all vestibular presentations to dizziness clinics and also has a lifetime prevalence of 2.4% in the general population. This form of vertigo is believed to be caused when calcium crystals found throughout the inner ear break loose and migrate into the lumen of the posterior semicircular canal. These crystals, or canaliths, then trigger abnormal stimulation of cells that signal the sensation of movement and the position of the head, resulting in vertigo.
