Vestibular Deficits in Deafness: Clinical Presentation, Animal Modeling, and Treatment Solutions.

Front Neurol 2022 4;13:816534. Epub 2022 Apr 4.

Unit Progressive Sensory Disorders, Pathophysiology and Therapy, Institut Pasteur, Institut de l'Audition, Université de Paris, INSERM-UMRS1120, Paris, France.

The inner ear is responsible for both hearing and balance. These functions are dependent on the correct functioning of mechanosensitive hair cells, which convert sound- and motion-induced stimuli into electrical signals conveyed to the brain. During evolution of the inner ear, the major changes occurred in the hearing organ, whereas the structure of the vestibular organs remained constant in all vertebrates over the same period.

Vestibulo-ocular dysfunction in mTBI: Utility of the VOMS for evaluation and management - A review.

NeuroRehabilitation 2022 ;50(3):279-296

Herbert Wertheim School of Optometry & Vision Science at the University of California, Berkeley, CA, USA.

Background: Individuals who have suffered a concussion/mild traumatic brain injury (mTBI) frequently report symptoms associated with vestibular and/or oculomotor dysfunction (VOD) like dizziness, nausea, fatigue, brain fog, headache, gait and neurocognitive impairments which are associated with the development of chronic symptoms. The Vestibular/Ocular Motor Screening (VOMS) tool has been established as a reliable and clinically relevant complement to use alongside a battery of post-concussion tests to improve screening and referral for further evaluation and treatment of VOD.

Objectives: This paper will review the pathoanatomy and symptomatology of common vestibular and oculomotor disorders after concussion, as well as the utility of the VOMS to assist in diagnosis, referral, and management. Read More

Minimum Stimulus Strategy: A step-by-step diagnostic approach to BPPV.

J Neurol Sci 2022 Mar 19;434:120158. Epub 2022 Jan 19.

Audiology & Vestibology Service, Centromedico Bellinzona, Bellinzona, Switzerland.

Benign Paroxysmal Positional Vertigo (BPPV) is among the most common vestibular disorders, characterized by brief vertigo spells triggered by head position changes with abrupt onset and rapid decrease. BPPV is ascribed to otoconial matter dislodged from utricular macula and attached to the cupula of the affected semicircular canal (cupulolithiasis) or free-floating within its lumen (canalolithiasis). According to the vestibulo-ocular reflex pathophysiology, each cupular deflection, either exciting or inhibiting the corresponding ampullary afferents, generates the contraction of specific extraocular muscles couples leading to pathognomonic nystagmus.

Machine Learning Techniques for Differential Diagnosis of Vertigo and Dizziness: A Review.

Sensors (Basel) 2021 Nov 14;21(22). Epub 2021 Nov 14.

School of Computer Science, Faculty of Engineering and Information Technology, University of Technology Sydney, Sydney 2007, Australia.

Vertigo is a sensation of movement that results from disorders of the inner ear balance organs and their central connections, with aetiologies that are often benign and sometimes serious. An individual who develops vertigo can be effectively treated only after a correct diagnosis of the underlying vestibular disorder is reached. Recent advances in artificial intelligence promise novel strategies for the diagnosis and treatment of patients with this common symptom. Read More

Department of Otolaryngology Head and Neck Surgery,Shenzhen Second People's Hospital,Shenzhen,518000,China.

By observing the nystagmus forms at different positions during Epley reduction in patients with posterior semicircular canal benign parochial positional vertigo(PC-BPPV), to compare the effects of the first reduction, and to further summarize the possible causes of reduction failure and the prognosis of patients with different nystagmus forms. A retrospective analysis of 191 PC-BPPV patients diagnosed with PC-BPPV showed that 95 cases had positive nystagmus during the reduction process(group A), 69 cases had no nystagmus (group B), and 27 cases had reverse nystagmus (group C). All the patients were diagnosed by G-Force BPPV and were treated through simulative Epley CRP. Read More

Episodic Positional Dizziness.

Authors:
Kevin A Kerber

Continuum (Minneap Minn) 2021 04;27(2):348-368

Purpose Of Review: This article provides a summary of the evaluation and treatment of patients presenting with episodic positional dizziness.

Recent Findings: Positional components are nearly ubiquitous among diagnoses of dizziness, so it can be challenging to classify patients with episodic positional dizziness simply based on the history of present illness. Overreliance on the presence of a report of positional components has likely resulted in misapplication or misinterpretation of positional testing and negative experiences with maneuvers to treat positional dizziness.
