Objective: To describe a unique case of definite neuroborreliosis presenting with bilateral vestibulopathy (BV) due to simultaneous involvement of both vestibular systems highlighted by a complete assessment for all five vestibular receptors.
Patient: A 72-year-old woman presented with disabling disequilibrium arisen about 4 weeks earlier and history of erythema migrans developing about 45 days before.
Interventions: Assessing all five vestibular receptors with the video-head impulse test (vHIT), the suppression head impulse paradigm (SHIMP) and vestibular evoked myogenic potentials (VEMPs), a severe bilateral vestibulopathy was diagnosed. IgG and IgM Borrelia-specific antibodies on patient serum and cerebrospinal fluid analysis confirmed the diagnosis of neuroborreliosis. Following diagnosis, a course of doxycycline was started and the patients received an individualized vestibular rehabilitation program.
Results: The patient exhibited slowly progressive improvements for disabling symptoms and the improving function of all five vestibular receptors was monitored with vHIT, SHIMP, and VEMPs over time.
Conclusions: This is the first case report of bilateral vestibulopathy likely caused by neuroborreliosis. Although neurotologic involvement is an uncommon complication in this condition, clinicians should consider a vestibular testing battery when addressed by patient's history and bedside vestibular findings.

Efficient gaze stabilization during video Active Gaze Shift Test (vAGST) in bilateral vestibulopathy.
Front Neurol
December 2024
Institut de Recherche Oto-Neurologique (IRON), Paris, France.
Introduction: While most head movements in daily life are active, most tools used to assess vestibular deficits rely on passive head movements. A single gain value is not sufficient to quantify gaze stabilization efficiency during active movements in vestibular deficit patients. Moreover, during active gaze shifts, anticipatory mechanisms come into play.

Objectives: This study aimed to determine if the presence of corrective saccades during video head impulse test (vHIT) stimulation of the bilateral posterior semicircular canals (PSCs) correlated with other vestibular test results, demographics, symptoms, or diagnoses.
Design: This study was a retrospective chart review where 1006 subjects' vHIT records were screened with 17 subjects meeting inclusion criteria for isolated bilateral PSC saccades.
Results: Of the 1006 patients undergoing vHIT testing, only 1.
Catch-Up Saccades in Vestibulo-Ocular Reflex Deficit: Contribution of Visual Information?
Ear Hear
December 2024
Institut national de la santé et de la recherche médicale, U1028, Centre National de Recherche Scientifique, UMR5292, Lyon Neuroscience Research Center, Integrative Multisensory Perception and ACTion Team, Lyon, France.
Objectives: Catch-up saccades help to compensate for loss of gaze stabilization during rapid head rotation in case of vestibular deficit. While overt saccades observed after head rotation are obviously visually guided, some of these catch-up saccades occur with shorter latency while the head is still moving, anticipating the needed final eye position. These covert saccades seem to be generated based on the integration of multisensory inputs.

Bilateral middle cerebellar peduncle (MCP) infarction is a rare manifestation of ischemic stroke. We report a middle-aged male patient who presented with acute onset of vertigo, left ear deafness, and severe ataxia. Magnetic resonance imaging (MRI) of the brain confirmed the presence of infarction in the bilateral middle cerebellar peduncles due to stenosis of the posterior circulation arteries.

This review attempts to analyze the relationship between the vestibular system and the circadian timing system. The activity of the biological clock allows an organism to optimally perform its tasks throughout the nychtemeron. To achieve this, the biological clock is subjected to exogenous factors that entrain it to a 24h period.
