The Vestibular System01:29

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Summary

Aging affects vestibular-evoked myogenic potentials (VEMPs) measured by galvanic vestibular stimulation (GVS). After age 60, GVS-VEMPs show prolonged latencies and reduced amplitude, likely due to fewer vestibular afferents.

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Gerontology

Background:

  • Vestibular-evoked myogenic potentials (VEMPs) assess vestibular function.
  • Galvanic vestibular stimulation (GVS) is a method to elicit VEMPs.
  • Aging is known to affect sensory systems, including the vestibular system.

Purpose of the Study:

  • To compare characteristic parameters of VEMPs elicited by GVS in healthy subjects across different age groups.
  • To determine the impact of aging on GVS-VEMPs.

Main Methods:

  • A prospective study was conducted at a university hospital.
  • Fifty-two healthy subjects were divided into five age groups.
  • VEMP testing was performed using GVS with an intensity of 5 mA for 1 ms.

Main Results:

  • Clear GVS-VEMPs were observed in all subjects younger than 60 years.
  • Prevalence of clear GVS-VEMPs did not significantly differ between younger and older groups (83% in the 60-69 group).
  • Significant differences in latency and amplitude were found; subjects over 60 had longer p13 and n23 latencies and lower p13-n23 amplitude.

Conclusions:

  • GVS-VEMP amplitude decline and latency prolongation after age 60 are observed.
  • These age-related changes may be attributed to a reduction in the number and caliber of vestibular afferents.
