Did you know forty percent of adults will experience significant dizziness at some time in their lives, and that nearly one in four emergency room visits includes a complaint of dizziness?

The vestibular system includes the parts of the inner ear and brain that process the sensory information involved with controlling balance and eye movements. If disease or injury damages these processing areas, vestibular disorders can result. Vestibular disorders can also result from or be worsened by genetic or environmental conditions, or occur for unknown reasons.

The most commonly diagnosed vestibular disorders include benign paroxysmal positional vertigo (BPPV), labyrinthitis or vestibular neuritis, Ménière’s disease, and secondary endolymphatic hydrops. Vestibular disorders also include superior semicircular canal dehiscence, acoustic neuroma, perilymph fistula, ototoxicity, enlarged vestibular aqueduct, migraine-associated vertigo, and Mal de Débarquement. Other problems related to vestibular dysfunction include complications from aging, autoimmune disorders, and allergies.
