Characterization of Thyroid Hormones Antivertigo Effects in a Rat Model of Excitotoxically-Induced Vestibulopathy.

Front Neurol 2022 25;13:877319. Epub 2022 May 25.

Aix Marseille Université-CNRS, Laboratoire de Neurosciences Cognitives, LNC UMR 7291, Marseille, France.

Impaired vestibular function induces disabling symptoms such as postural imbalance, impaired locomotion, vestibulo-ocular reflex alteration, impaired cognitive functions such as spatial disorientation, and vegetative deficits. These symptoms show up in sudden attacks in patients with Ménière or neuritis and may lead to emergency hospitalizations. To date, however, there is no curative solution to these pathologies and the effectiveness of treatments used to reduce symptoms in the management of patients is discussed. Read More

Front Neurol 2022 16;13:845707. Epub 2022 May 16.

Department of Neurology, Ajou University Medical Center, Ajou University School of Medicine, Suwon, South Korea.

Background: This study aimed to determine the clinical significance of acute vestibular syndrome (AVS)/acute imbalance syndrome (AIS) in posterior circulation stroke (PCS) and how it should be addressed in the thrombolysis code.

Toward a Digital Health Intervention for Vestibular Rehabilitation: Usability and Subjective Outcomes of a Novel Platform.

Front Neurol 2022 29;13:836796. Epub 2022 Mar 29.

Academic Unit of Neurology, School of Medicine, Trinity College Dublin, Dublin, Ireland.

Digital technologies are increasingly available and are reducing in cost. There is an opportunity to move to a digital health approach in vestibular rehabilitation (VR), but there is a paucity of suitable systems available and a consequent lack of evidence to support their use. This study aimed to investigate a novel digital platform developed specifically for VR (comprising clinician software, a wearable sensor, and a patient-facing app). Read More

Downbeat nystagmus becomes attenuated during walking compared to standing.

J Neurol 2022 Apr 12. Epub 2022 Apr 12.

German Center for Vertigo and Balance Disorders, University Hospital, LMU, Munich, Germany.

Downbeat nystagmus (DBN) is a common form of acquired fixation nystagmus related to vestibulo-cerebellar impairments and associated with impaired vision and postural imbalance. DBN intensity becomes modulated by various factors such as gaze direction, head position, daytime, and resting conditions. Further evidence suggests that locomotion attenuates postural symptoms in DBN. Read More

Nystagmus only with fixation in the light: a rare central sign due to cerebellar malfunction.

J Neurol 2022 Jul 9;269(7):3879-3890. Epub 2022 Apr 9.

Department of Neurology, Dizziness Center, Clinical Neuroscience Center, Seoul National University Bundang Hospital, Seongnam, South Korea.

Fixation nystagmus refers to the nystagmus that appears or markedly increases with fixation. While relatively common in infantile (congenital) nystagmus, acquired fixation nystagmus is unusual and has been ascribed to lesions involving the cerebellar nuclei or the fibers projecting from the cerebellum to the brainstem. We aimed to report the clinical features of patients with acquired fixation nystagmus and discuss possible mechanisms using a model simulation and diagnostic significance. Read More

Development and Content Validity of the Bilateral Vestibulopathy Questionnaire.

Front Neurol 2022 17;13:852048. Epub 2022 Mar 17.

Division of Balance Disorders, Department of Otorhinolaryngology and Head and Neck Surgery, Maastricht University Medical Center, School for Mental Health and Neuroscience, Maastricht, Netherlands.

Background: To date, the burden and severity of the full spectrum of bilateral vestibulopathy (BVP) symptoms has not yet been measured in a standardized manner. Since therapeutic interventions aiming to improve BVP symptoms are emerging, the need for a new standardized assessment tool that encompasses the specific aspects of BVP arises. Therefore, the aim of this study was to develop a multi-item Patient Reported Outcome Measure (PROM) that captures the clinically important symptoms of BVP and assesses its impact on daily life.

In vivo neuroplasticity in vestibular animal models.

Mol Cell Neurosci 2022 05 22;120:103721. Epub 2022 Mar 22.

Department of Neurology, University Hospital, LMU Munich, Germany; German Center for Vertigo and Balance Disorders, DSGZ, LMU Munich, Germany; Munich Cluster of Systems Neurology, SyNergy, Munich, Germany.

An acute unilateral vestibulopathy leads to symptoms of vestibular tone imbalance, which gradually decrease over days to weeks due to central vestibular compensation. Animal models of acute peripheral vestibular lesions are optimally suited to investigate the mechanisms underlying this lesion-induced adaptive neuroplasticity. Previous studies applied ex vivo histochemical techniques or local in vivo electrophysiological recordings mostly in the vestibular nucleus complex to delineate the mechanisms involved. Read More

Agreement Between Caloric and Horizontal Video Head Impulse Testing in School-Aged Children Presenting With Dizziness.

Am J Audiol 2022 Jun 14;31(2):299-304. Epub 2022 Mar 14.

Division of Vestibular Sciences, Vanderbilt University Medical Center, Nashville, TN.

Objective: The purpose of this investigation was to determine the relationship between the horizontal semicircular canal video head impulse test (hvHIT) and the caloric test in a sample of school-age children evaluated due to complaints of dizziness or imbalance. In adults, these two tests provide different but complementary information regarding vestibular function and/or pathology. However, the most common causes of vestibular loss in children are different than those in adults, and it is not clear how these two tests of horizontal semicircular canal function are related in a pediatric population.

Feasibility of Telemedical HINTS (Head Impulse-Nystagmus-Test of Skew) Evaluation in Patients With Acute Dizziness or Vertigo in the Emergency Department of Primary Care Hospitals.

Front Neurol 2021 11;12:768460. Epub 2022 Feb 11.

Department of Neurology, TEMPiS Telestroke Center, Academic Teaching Hospital of the Ludwig-Maximilians-University, München Klinik, Munich, Germany.

Background: Acute dizziness, vertigo and imbalance are common symptoms in emergency departments. Stroke needs to be distinguished from vestibular diseases. A battery of three clinical bedside tests (HINTS: Head Impulse Test, Nystagmus, Test of Skew) has been shown to detect stroke as underlying cause with high reliability, but implementation is challenging in primary care hospitals.

Background: Uncompensated vestibular hypofunction can result in symptoms of dizziness, imbalance, and/or oscillopsia, gaze and gait instability, and impaired navigation and spatial orientation; thus, may negatively impact an individual's quality of life, ability to perform activities of daily living, drive, and work. It is estimated that one-third of adults in the United States have vestibular dysfunction and the incidence increases with age. There is strong evidence supporting vestibular physical therapy for reducing symptoms, improving gaze and postural stability, and improving function in individuals with vestibular hypofunction.

Vestibular compensation of otolith graviceptive dysfunction in stroke patients.

Eur J Neurol 2022 03 1;29(3):905-909. Epub 2021 Dec 1.

Department of Neurology, University Hospital, Ludwig-Maximilians-University, Munich, Germany.

Background And Purpose: A sensitive and frequent clinical sign of a vestibular tone imbalance is the tilt of the perceived subjective visual vertical (SVV). There are no data yet focusing on lesion location at the cortical level as a factor for predicting compensation from the tilt of the SVV.

Methods: With modern voxelwise lesion behavior mapping analysis, the present study determines whether lesion location in 23 right-hemispheric cortical stroke patients with an otolith dysfunction could predict the compensation of a vestibular tone imbalance in the chronic stage. Read More
