Vestibular and visual influence on postural stability and egomotion perception in persistent postural-perceptual dizziness (PPPD).

BACKGROUND: Patients suffering from persistent postural-perceptual dizziness (PPPD) often experience postural instability that worsens when exposed to visual motion stimuli. We investigated how different visual motion stimuli affect patients' postural sway and their perceived egomotion during stance. METHODS: 28 PPPD patients and 26 gender and healthy control subjects (HC) underwent posturographic measurements on a firm or foam platform while being exposed to either vestibular or visual motion stimuli or their combination. Vestibular stimuli were applied via 1.3 mA galvanic vestibular stimula…

Prevalence and Risk Factors of Self-reported Dizziness in Post-9/11 Service Members and Veterans.

INTRODUCTION: Dizziness is prevalent in the general population, but little is known about its prevalence in the U.S. military population. Dizziness is commonly associated with blast exposure and traumatic brain injury (TBI), but the potential independent contributions of blast and TBI have yet to be evaluated. This study's goal was to estimate the prevalence of dizziness among post-9/11 service members and Veterans and to examine independent and joint associations between military TBI history, blast exposure, and self-reported dizziness. MATERIALS AND METHODS: The study sample consisted of se…

Imbalance and dizziness caused by unilateral vestibular schwannomas correlate with vestibulo-ocular reflex precision and bias.

Imbalance and dizziness are disabling symptoms for many patients with vestibular schwannomas (VS) but symptom severity typically does not correlate with the vestibulo-ocular reflex (VOR) amplitude-based metrics used to assess peripheral vestibular damage. In this study, we tested the hypothesis that imbalance and dizziness in patients with VS relate to VOR metrics that are not based on response amplitude. Twenty-four patients with unilateral, sporadic VS tumors were studied, and objective (balance) and subjective (dizziness) vestibular dysfunction was quantified. The VOR was tested using two y…

Dizziness and syncope after subclavian steal: A case report of a rarely symptomatic, common vascular disorder.

Subclavian steal syndrome (SSS) is a manifestation of vertebrobasilar artery insufficiency due to stenosis of the proximal subclavian artery. It is a common vascular disorder; however, most patients are asymptomatic, and the disorder is commonly found incidentally during imaging. Nevertheless, some patients may present with arm ischemia or signs and symptoms of vertebrobasilar insufficiency, such as vertigo, dizziness, diplopia, ataxia, dysarthria, and syncopal episodes. We present a case of a male patient who presented with sudden onset dizziness, syncopal episodes, and blood pressure discrep…

Cerebral Responses to Stationary Emotional Stimuli Measured by fMRI in Women with Persistent Postural-Perceptual Dizziness.

Introduction  Persistent postural-perceptual dizziness (PPPD) is a functional vestibular disorder characterized by chronic dizziness, unsteadiness, and hypersensitivity to motion. Preexisting anxiety disorders and neurotic personality traits confer vulnerability to PPPD. High anxiety during acute vertigo or dizziness incites it. A functional magnetic resonance imaging (fMRI) study of chronic subjective dizziness found unexpectedly hypoactive responses to vestibular stimulation in cortical regions that integrate threat assessment and spatial perception. Objective  This fMRI study used non-movin…
