Paroxysmal positional vertigo is more common in older adults, affecting over 40% of those 70 and older. The nystagmus observed in these elderly patients is typically the Barany type, similar to younger individuals.

Area of Science:

  • Geriatrics
  • Neurology
  • Otolaryngology

Background:

  • Dizziness is a common complaint among the elderly.
  • Paroxysmal positional vertigo (PPV) is a frequent cause of dizziness.
  • Age-related changes may influence the prevalence and presentation of PPV.

Purpose of the Study:

  • To determine the prevalence of PPV in elderly patients (70 years and older) presenting with dizziness.
  • To compare the prevalence of PPV in the elderly with that in younger age groups.
  • To characterize the type of nystagmus observed during positional paroxysms in elderly patients.

Main Methods:

  • Retrospective chart review of 806 patients aged 70+ with dizziness.
  • Analysis of patient history for symptoms suggestive of PPV.

  • Clinical elicitation of positional paroxysms and observation of nystagmus.
  • Classification of nystagmus type.

    • Main Results:

    • 40.7% of elderly patients (328/806) reported symptoms suggestive of PPV.
    • This prevalence is higher than in younger cohorts (33.7% in those ≤50 years, 26.6% in those ≤40 years).
    • In 158 patients with elicited paroxysms, nystagmus was observed in 135, predominantly of the Barany type.

    Conclusions:

    • The prevalence of paroxysmal positional vertigo increases with advancing age.
    • The nystagmus associated with PPV in the elderly is typically the Barany type, consistent with findings in younger age groups.
    • PPV is a significant contributor to dizziness in the geriatric population.
