title: Vestibular disorders in elderly patients: characteristics, causes and consequences.
abstract: BACKGROUND
  This study assessed vestibular disorders in elderly patients, describing the causes, clinical characteristics, therapies and treatment outcomes.
  
  
  METHODS
  Five-year hospital-based prospective study, conducted at the ENT clinic of a tertiary referral center. Subjects were consecutive elderly patients with dizziness, treated and followed-up for a minimum of six months. Data was generated using structured questionnaire and case record files. Analyzed results were presented in simple descriptive forms as graphs and tables.
  
  
  RESULTS
  Among the elderly patients, prevalence of vestibular disorders was 18.6%, 49.1% were retired, 71.9% were married, M:F was 1:1.1. Mean age±SD were 69.4±1.1 and 69.0±0.8 years for males and females respectively. 56.9% of the patients presented early on experiencing the vestibular symptoms. The symptoms were associated with nausea or vomiting in 26.3%, with an aura in 12.3%. While 50.9% of the patients experienced intermittent symptoms, laterality of the symptoms was not clear in 45.6%. Positional vertigo was diagnosed in 33.3% while in 17.5%, the symptoms could be attributable to previous trauma or assaults. 31.6% of the elderly were referred to ENT surgeons by other specialties, 45.6% were managed with multidisciplinary approach, while 82.5% had the vestibular symptoms initially controlled with labyrinthine sedatives. At follow-up, 43.9% had intermittent periods of recurrence of symptoms.
  
  
  CONCLUSIONS
  Prevalence of vestibular disorders in elderly patients is high, most patients present early with intermittent, relatively innocuous symptoms which may be difficult to lateralize. Positional vertigo was the most common cause, it is frequently relieved with labyrinthine sedatives but tends to recur intermittently.
