title: The treatment and natural course of peripheral and central vertigo.
abstract: BACKGROUND
  Recent studies have extended our understanding of the pathophysiology, natural course, and treatment of vestibular vertigo. The relative frequency of the different forms is as follows: benign paroxysmal positional vertigo (BPPV) 17.1%; phobic vestibular vertigo 15%; central vestibular syndromes 12.3%; vestibular migraine 11.4%; Menière's disease 10.1%; vestibular neuritis 8.3%; bilateral vestibulopathy 7.1%; vestibular paroxysmia 3.7%.
  
  
  METHODS
  Selective literature survey with particular regard to Cochrane reviews and the guidelines of the German Neurological Society.
  
  
  RESULTS
  In more than 95% of cases BPPV can be successfully treated by means of liberatory maneuvers (controlled studies); the long-term recurrence rate is 50%. Corticosteroids improve recovery from acute vestibular neuritis (one controlled, several noncontrolled studies); the risk of recurrence is 2-12%. A newly identified subtype of bilateral vestibulopathy, termed cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS), shows no essential improvement in the long term. Long-term high-dose treatment with betahistine is probably effective against Menière's disease (noncontrolled studies); the frequency of episodes decreases spontaneously in the course of time (> 5 years). The treatment of choice for vestibular paroxysmia is carbamazepine (noncontrolled study). Aminopyridine, chlorzoxazone, and acetyl-DL-leucine are new treatment options for various cerebellar diseases.
  
  
  CONCLUSIONS
  Most vestibular syndromes can be treated successfully. The efficacy of treatments for Menière's disease, vestibular paroxysmia, and vestibular migraine requires further research.
