Active clinical trials for "Vertigo"

Clinical investigation of a medical device (CAVA) for recording eye movements. Patients suffering from diagnosed dizziness conditions will wear the device for 23 hours a day, for 30 days. The device will capture normal eye movement data as well as data corresponding to any dizzy events experienced. At the end of the trial, the data will be downloaded and a scientist will perform a blinded analysis of the data. Specifically, they will attempt to identify the dates on which dizziness was reported.

Obstructive Sleep Apnea may cause dizziness or vertigo through hypoxia of the vestibular nuclei in the brain. Treating sleep apnea may improve dizziness or vertigo.

Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.

DeepDoc is an AI-based decision support system for the early etiology diagnosis of neurological diseases using clinical data points from patients admitted to hospital within 24 hours.This study aims to evaluate whether the diagnosis of the DeepDoc AI-based decision support system is better than the doctor's initial diagnosis by a multi-center, superiority diagnostic study.

The score on the Dizziness Handicap Inventory (short version) before and after hearing aid fitting and usage will be compared

To evaluate the function of vestibular system in patients with chronic suppurative otitis media safe type.

The alternate binaural bithermal caloric test (ABBT) is a well established examination in the evaluation of the dizzy patient. ABBT is useful in detecting the side of peripheral vestibulopathy by stimulating each ear separately, it contributes to the diagnosis of bilateral vestibular involvement when all responses to cold and warm stimuli are reduced, and adds to the differentiation of peripheral from central vestibular involvement by measuring the fixation-induced inhibition of the caloric response. In spite of these benefits, ABBT is the most time-consuming part of the electronystagmography/Videonystagmography (ENG/VNG) test battery, and frequently causes significant inconvenience to the patient due to the repeated extreme vestibular stimuli. The head impulse test (HIT) assesses vestibular function by brisk, passive rotations of the head in the plane of the examined semicircular canals. Whenever the vestibulo-ocular reflex (VOR) is deficient, this maneuver would produce catch-up saccades aiming to the re-fixation of the eyes on the target. Hence, both residual VOR and catch-up saccades act synergistically to stabilize gaze. The HIT requires only several minutes and might cause minimal discomfort only. The study hypothesis is that the HIT recorded by standard VNG equipment of the VNG system would provide diagnostic information on the side of vestibular involvement matching that of the ABBT.

Patients hospitalized at the rehabilitation department at the hospital will fill a questionnaire regarding dizziness and ear diseases, and the Dizziness Handicap Inventory, and then will be examined by an ENT physician, followed by a video Head Impulse Test (vHIT) study.
