The Effect of Sleep Deprivation on the Vestibulo‐Ocular Reflex and Vestibular Adaptation in Healthcare Night‐Shift Workers

The Laryngoscope, Volume 135, Issue 9, Page 3364-3370, September 2025.
This study examined the effects of sleep deprivation on the vestibulo‐ocular reflex (VOR) in healthcare night‐shift workers. Results showed a significant reduction in VOR gain (7.5%) during passive head movements toward far targets after a night shift, whereas other VOR functions and gaze stability remained unaffected.

Comparative utility of vestibular function tests in patients with peripheral and central vestibular dysfunction

Journal of Otology
Background: Bithermal caloric irrigation, video head impulse test (vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral ...

Age Is a Greater Influence on Small Saccades Than Target Size in Normal Subjects on the Horizontal Video Head Impulse Test

Frontiers in Neurology, 2019
Objective: This study sought to investigate whether the size of the target used in the horizontal vHIT has an effect on the saccade profile of healthy subjects, and to expand upon previous work linking age to the existence of small vHIT saccades.Methods:

Feasibility of Using the Video-Head Impulse Test to Detect the Involved Canal in Benign Paroxysmal Positional Vertigo Presenting With Positional Downbeat Nystagmus

Frontiers in Neurology, 2020
Positional downbeat nystagmus (pDBN) represents a relatively frequent finding. Its possible peripheral origin has been widely ascertained. Nevertheless, distinguishing features of peripheral positional nystagmus, including latency, paroxysm and torsional

Contrast Agent Uptake in Endolymphatic Sac and Duct: Inverse Relation to Endolymphatic Hydrops

The Laryngoscope, Volume 135, Issue 8, Page 2914-2922, August 2025.
Question: Is there a disease‐specific abnormality of the endolymphatic sac and duct system (ES/ED) in delayed, contrast‐enhanced inner ear MRI in patients with Ménière's disease (MD) and vestibular migraine (VM) that correlates with the endolymphatic hydrops (ELH)?

Evaluation of the Peripheral Vestibular System due to Inner Ear Barotrauma in the Hyperbaric Environment

Laryngoscope Investigative Otolaryngology, Volume 10, Issue 4, August 2025.
This study investigates changes that may occur in the peripheral vestibular system due to inner ear barotrauma in self‐contained underwater breathing apparatus (SCUBA) divers exposed to hyperbaric environments. Our findings demonstrate that the significant increase in c‐VEMP response amplitudes among SCUBA divers exposed to hyperbaric environments ...

Reduced Vestibular Function is Associated With Cortical Surface Shape Changes in the Frontal Cortex

Human Brain Mapping, Volume 46, Issue 10, July 2025.
We identified significant cortical surface shape changes in focal areas of the prefrontal cortex that correlate with age‐related vestibular dysfunction in 117 older adults from the Baltimore Longitudinal Study of Aging. These findings provide important insights into mechanisms linking vestibular decline, cognitive impairment, and fall risk in aging ...

Corrective saccades with normal VOR gain in Vestibular Schwannoma

Revista Portuguesa Otorrinolaringologia e Cirurgia de Cabeça e Pescoço
The Video Head Impulse Test (vHIT) is used to assess vestibular function. It has been shown to be valuable in patients with Vestibular Schwannoma (VS). We present a case of a 64-year-old male with a 6mm VS in the left internal acoustic canal, detected
