Ear Hear 2021 Apr 22. Epub 2021 Apr 22.

1Department of Translational Neurosciences, University of Antwerp, Antwerp, Belgium 2Department of Otorhinolaryngology-Head and neck surgery, Antwerp University Hospital, Edegem, Belgium 3Department of Education, Health & Social Work, University College Ghent, Ghent, Belgium 4Department of Neurology, UZ Brussel and Center for Neurosciences (C4N), VUB, Brussels, Belgium 5Department of Biomedical Sciences and Institute Born-Bunge, University of Antwerp, Antwerp, Belgium 6Department of Neurology, Antwerp University Hospital, Edegem, Belgium.

Importance: Given the rising prevalence of patients with dementia and those at risk for it, early identification is prioritized. As vestibular dysfunction is associated with Alzheimer's disease (AD) and may contribute to its onset, vestibular assessment may yield an opportunity in early dementia screening.

Objective: This systematic review structures and compares the different raw outcome measures used to assess vestibular function while comparing older adults with preserved cognition to individuals with cognitive impairment, either suffering from mild cognitive impairment (MCI) or AD. Read More

Clinical Application of the Vestibular Stimulation Effect on Balance Disorders with Dementia.

Curr Alzheimer Res 2021 Mar 23. Epub 2021 Mar 23.

Department of Neurology, Division of Clinical Medicine, Faculty of Medicine, University of Tsukuba, Tsukuba, Ibaraki. Japan.

Background: In a previous study on Alzheimer's disease (AD), we showed that vestibular dysfunction derived from cerebral disorders contributes to balance disorders. No previous clinical study has attempted to prevent the progression of balance disorders in dementia patients through vestibular stimulation using an air caloric device.

Objective: The purpose of this pilot study was to delay the progression of balance disorders by inducing vestibular compensation, specifically by utilizing the effect of vestibular stimulation to activate the cerebrum. Read More

[Research advances on mechanism and lesion location of vertical nystagmus].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2020 Feb;34(2):186-189

Vertical nystagmus is a vertical nystagmus caused by structural abnormalities and/or dysfunction of the central vestibular system and observed in situ in the center of the eyeball. There are two kinds of nystagmus (UBN) and downbeat nystagmus (DBN) according to the direction of nystagmus. The diagnosis of UBN is mainly made by naked eye or electronystagmography/viewer.

J Vestib Res 2019;29(6):309-314

Santa Casa de Sao Paulo School of Medical Sciences, CEP 01221-010 São Paulo, SP, Brasil.

Objective: To measure the time required in patients with tympanic perforation to reverse paradoxical stimulation (reverse pseudo-nystagmus) and to create a physical model of the process.

Method: An analytical, observational, cross-sectional study with vestibular evaluation (electronystagmography) of 52 individuals with tympanic membrane perforation without otorrhea or concomitant disease.

The evaluation of gravitational recognition in patients with spinocerebellar degeneration using Listing's plane.

Acta Otolaryngol 2019 Jul 20;139(7):581-587. Epub 2019 May 20.

a Department of Otolaryngology , Tokyo Medical and Dental University , Tokyo , Japan.

The thickness of Listing's plane accurately reflects gravitational recognition, constructed through the integration of visual, vestibular, and proprioceptive sensory input in the neural integrator of the central nervous system. Spinocerebellar degeneration (SCD) is a progressive degenerative disease mainly involving the cerebellum and brainstem that leads to destabilize the gravitational recognition, and may thicken thickening of Listing's plane. The aim of this study is to evaluate the gravitational recognition in response to positional change in patients with SCD, using the thickness of Listing's plane as a parameter. Read More

The Eight Years' War: Court Sides With TMA in Long-Running Chiropractic Case on Vestibular Testing.

Authors:
Joey Berlin

Tex Med 2019 Feb 1;115(2):32-33. Epub 2019 Feb 1.

In a split victory, TMA once again prevailed in November 2018 when the Third Court of Appeals upheld a trial court's decision that chiropractors don't have the authority to perform vestibular-ocular-nystagmus testing (VONT). However, a recent change to state law caused the appeals court to find in the Texas Board of Chiropractic Examiners' favor on the use of the word "diagnosis" in the board's administrative rules - meaning chiropractors can diagnose, but only within their scope of practice.
