Cognitive Dysfunction in Patients With Vestibular Disorders

Cross-Sectional Analysis of Cognitive Dysfunction in Patients With Vestibular Disorders: Objective:

The relationship of cognitive dysfunction and vestibular dysfunction has been established by various studies. However, the available Patient-Reported Outcome Measures questionnaires that address the main vestibular complaint fail to highlight this domain of dysfunction in this patient population. The objective of this study was to quantify and compare cognitive impairment using a validated cognitive questionnaire across several vestibular diagnoses.

Study Design:

Cross-sectional study of 186 patients presenting to a tertiary care vestibular clinic with a diagnosis of vestibular migraine, Meniere’s disease (MD), benign positional paroxysmal vertigo, or persistent postural-perceptual dizziness (PPPD). Patients completed the Cognitive Failures Questionnaire (CFQ) and the Dizziness Handicap Inventory (DHI).

Results:

Mean CFQ scores for this cohort were significantly higher than similarly aged published controls (34.9/100 versus 31.3/100; p
