Many epidemiologic studies of vestibular disorders are based on responses to questionnaires which have not been tested against objective tests of the vestibular system.

The goal was to determine if the dizziness and balance questions used in the National Health Interview Survey (NHIS) are valid and predict performance on objective tests of the vestibular system (VNG).

Data from 367 participants recruited from the community, aged 21.4 to 87.6 years, were collected in the Otolaryngology department at a tertiary care center. They were asked the eight NHIS questions twice, at least 30 minutes apart and were tested on VNG.

Question responses changed from Test 1 to Test 2 and differed between males and females. "Yes" responses did not predict abnormal VNG responses, for the total group and when the group was categorized into younger (<60 years) and older (>60 years) subjects. The sensitivity and specificity of all questions was low.

The NHIS questions provide some information about what people recall of their experiences, but they may not provide insight into the diagnostic prevalence of vestibular and balance disorders because the sensitivity and specificity are too low. Questionnaire-based epidemiologic studies should be interpreted with caution.

The diagnosis of Menière's disease (MD) is made according to diagnostic criteria, the last revision of which was in 2015. For diagnosis, symptoms are weighted with audiometric findings and this can be challenging in individual patients.

To analyze patient's characteristics and symptoms in a real-life cohort of 96 patients with diagnosed MD regarding sociodemographic parameters, clinical specifics, and audiometry.

Prospective clinical patient registry containing demographic and socioeconomic parameters, symptoms, as well as pure-tone audiometry data.

31 patients with definite MD, and 36 with probable MD were identified. 29 patients showed typical clinical signs of MD, but did not meet the full diagnostic criteria, and were considered separately. Mean duration of symptoms prior to presentation was 3.9±4.6 years. Significant differences between categories were found regarding aural fullness, tinnitus, and fluctuating hearing. If multiple audiograms were available, 28.6 %(6/21) documented fluctuating hearing.

Current diagnostic criteria probably do not represent patients with monosymptomatic presentation or an early stage very well. Long-term follow-up with repeated audiometry is advisable.

Parkinson's disease (PD) is a common multi-system neurodegenerative disorder with possible vestibular system dysfunction, but prior vestibular function test findings are equivocal.

To report and compare vestibulo-ocular reflex (VOR) gain as measured by the video head impulse test (vHIT) in participants with PD, including tremor dominant and postural instability/gait dysfunction phenotypes, with healthy controls (HC).

Forty participants with PD and 40 age- and gender-matched HC had their vestibular function assessed. Lateral and vertical semicircular canal VOR gains were measured with vHIT. VOR canal gains between PD participants and HC were compared with independent samples t-tests. SCH66336 order Two distinct PD phenotypes were compared to HC using Tukey's ANOVA. The relationship of VOR gain with PD duration, phenotype, severity and age were investigated using logistic regression.

There were no significant differences between groups in vHIT VOR gain for lateral or vertical canals. There was no evidence of an effect of PD severity, phenotype or age on VOR gains in the PD group.

The impulsive angular VOR pathways are not significantly affected by the pathophysiological changes associated with mild to moderate PD.

Self-motion misperception has been observed in vestibular patients during asymmetric body oscillations. This misperception is correlated with the patient's vestibular discomfort.

To investigate whether or not self-motion misperception persists in post-ictal patients with Ménière's disease (MD).

Twenty-eight MD patients were investigated while in the post-ictal interval. Self-motion perception was studied by examining the displacement of a memorized visual target after sequences of opposite directed fast-slow asymmetric whole body rotations in the dark. The difference in target representation was analyzed and correlated with the Dizziness Handicap Inventory (DHI) score. The vestibulo-ocular reflex (VOR) and clinical tests for ocular reflex were also evaluated.

All MD patients showed a noticeable difference in target representation after asymmetric rotation depending on the direction of the fast/slow rotations. This side difference suggests disruption of motion perception. The DHI score was correlated with the amount of motion misperception. In contrast, VOR and clinical trials were altered in only half of these patients.

Asymmetric rotation reveals disruption of self-motion perception in MD patients during the post-ictal interval, even in the absence of ocular reflex impairment. Motion misperception may cause persistent vestibular discomfort in these patients.

Persistent Postural Perceptual Dizziness (PPPD) is a newly defined condition which was added to the International Classification of Vestibular Disorders in 2017. Little is known about its impact on patients.

The goal of this study was to analyze the symptomology, epidemiology and impact of PPPD on patients.

A retrospective chart review was done to identify patients who attended the Multidisciplinary Dizziness Clinic (MDC) and were diagnosed with PPPD. Responses to demographic questions, health-related quality of life surveys and several well-validated questionnaires commonly used to assess dizziness severity were analyzed.

One hundred patients were diagnosed with PPPD between March 2017 and January 2019, of which 80%(80/100) were females. The average Dizziness Handicap Index score was 60.3±19.0. Responses to the Patient Health Questionnaire classified 53 patients (53/99;53.5%) as moderately to severely depressed. Sixty-four patients (64/100;64.0%) were minimally or mildly anxious according to the Generalized Anxiety Disorder scale.
