Reduced vestibular perception thresholds in persistent postural-perceptual dizziness- a cross-sectional study.

ABSTRACT:

Background

Persistent postural-perceptual dizziness (PPPD) is the most common functional vestibular disorder. A multisensory mismatch altered by psychological influences is considered to be an important pathophysiological mechanism. Increased cortical and subcortical excitability may play a role in the pathophysiology of PPPD. We hypothesized that decreased motion perception thresholds reflect one mechanism of the abnormal vestibular responsiveness in this disorder. We investigated the vestibular perception thresholds and the vestibular ocular reflex with a rotatory chair experiment to gain insights in the processing and adaption to vestibular provocation.

Methods

In this cross-sectional study 26 female PPPD patients and 33 healthy female age matched controls (HC) were inves
