Summary

Aging significantly impacts vestibular evoked myogenic potential (VEMP) responses, with reduced response rates and amplitude in individuals over 60. These findings highlight age-related changes in the sacculocollic reflex pathway.

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Gerontology

Background:

  • Vestibular evoked myogenic potential (VEMP) assesses the sacculocollic reflex integrity.
  • Aging is known to affect vestibular-ocular reflex pathways.
  • The influence of aging on the sacculocollic reflex pathway via VEMP is not well-established.

Purpose of the Study:

  • To investigate the effect of aging on the sacculocollic reflex pathway using VEMP.
  • To determine how VEMP parameters change with increasing age.

Main Methods:

  • Prospective study conducted at an academic tertiary referral center.
  • Eighty healthy subjects were divided into four age groups (<20, 21-40, 41-60, >60 years).
  • VEMP responses were recorded, analyzing response rate, p13 latency, n23 latency, amplitude, and interaural difference ratio.

Main Results:

  • VEMP response rates significantly decreased in individuals over 60 (60%) compared to younger groups (98-90%).
  • VEMP amplitude negatively correlated with age, while n23 latency showed a positive correlation.
  • P13 latency showed a trend towards prolongation with age, but not significantly.

Conclusions:

  • Aging, particularly over 60, markedly reduces VEMP response rates and amplitude, suggesting deterioration of saccular and neural functions.
  • Age-related changes in VEMP parameters necessitate age-specific reference values for accurate clinical interpretation.
  • These findings underscore the importance of considering age when evaluating VEMP responses in patients with vestibular disorders.
