Application of the Barany Society's Presbyvestibulopathy Criteria in Older Adults With Chronic Dizziness

Abstract

ObjectiveTo evaluate the older adults with chronic dizziness using the Barany Society's presbyvestibulopathy (PVP) diagnostic criteria and to assess the clinical usability of the criteria.Study DesignRetrospective study.SettingSingle tertiary medical center.MethodsAmong a total of 1964 patients aged 60 years or older, 55 patients who had symptoms suitable for the PVP criteria and who underwent all 3 vestibular function tests were analyzed. Of these 55 patients, 13 patients were diagnosed with PVP based on the peripheral vestibular hypofunction criteria; the remaining 42 patients were categorized as patients without PVP.ResultsIn both patients with PVP and patients without PVP, postural imbalance or unsteadiness was the most frequently reported vestibular symptom. The rotatory chair test contributed the most to the quantitative diagnosis of PVP (6 of 13), followed by the caloric response test (3 of 13) and video head impulse test (vHIT; 2 of 13). When we included the presence of catch‐up saccades in addition to the vHIT gain in the diagnostic criteria, 5 patients without PVP were additionally diagnosed with PVP. Furthermore, when accounting for the inclusion of catch‐up saccades, patients who experienced recurrent falls demonstrated a significantly higher rate of impairments in the lateral and posterior semicircular canals according to the multivariate analysis.ConclusionConsidering the catch‐up saccades in addition to vHIT gain seemed to contribute to the diagnosis of PVP and prediction of recurrent fall risks in older adults. Further studies are needed to solidify the diagnostic criteria for PVP.
