VESTIBULAR DISORDERS

An estimated 20% of the general population is affected by a vestibular disorder.¹
At least half of the overall United States population is affected by a balance or vestibular disorder sometime during their lives.²
Approximately 15 out of every 1000 individuals consult their family physician each year with complaints of vertigo, dizziness, or imbalance; half the individuals over the age of 65 will develop positional vertigo.³
Of all falls suffered by the elderly, 50% are reported to be the result of vestibular problems.⁴
In approximately 15% of vestibular patients, the cause cannot be recognized.¹
Traditional vestibular function tests fail to establish a localizing diagnosis that can account for a patient's symptoms in a reported 30% to 50% of cases.⁵
Inner ear problems may not be amenable to surgical treatment, and pharmacological treatment of these conditions with vestibular suppressants often retards the recovery process.³
Vestibular dysfunction is a prominent part of balance disorders, particularly in the elderly, and is a significant source of morbidity.⁶
