title: The results of vestibular evoked myogenic potentials, with consideration of age-related changes, in vestibular neuritis, benign paroxysmal positional vertigo, and Meniere's disease.
abstract: CONCLUSIONS
  We interpreted VEMP findings in patients with the three major peripheral vertigo diseases, taking age-related changes into consideration. We found different abnormal VEMP rates among the three diseases, as well as differences in the proportion of parameters that were abnormal, according to the type of disease.
  
  
  OBJECTIVE
  Vestibular neuritis, benign paroxysmal positional vertigo (BPPV), and Meniere's disease, common diseases that cause peripheral vertigo, often affect the saccule or inferior vestibular nerve, which are pathways of vestibular evoked myogenic potential (VEMP). Also, aging could have a primary effect on diminished VEMP responses. Our study investigated VEMP the findings in patients with the diseases in relation to their age.
  
  
  METHODS
  A total of 134 patients with vestibular neuritis, 62 with BPPV, and 29 with Meniere's disease were enrolled in this study. The VEMP findings in patients within the three disease groups were interpreted using our own normative ranges according to age.
  
  
  RESULTS
  Abnormal VEMP rates in the vestibular neuritis, BPPV, and Meniere's disease groups were 36.6%, 25.8%, and 69%, respectively. The proportion of prolonged p13 latency in BPPV patients with abnormal VEMP responses was relatively high compared with the other two diseases. VEMP asymmetry in the patients with Meniere's disease was relatively high.
