Vertigo

The purpose of this study is to develop and validate methods to use hearing aids equipped with embedded sensors and artificial intelligence to assist in the assessment of fall risk and in the implementation of interventions aimed at reducing the risk of falling, as well as to improve speech intelligibility in quiet and in background noise, track physical activity, and social engagement. The investigators hope is that the knowledge that is generated through this study will ultimately translate to the clinical setting and will help reduce the likelihood that individuals experience a fall, and improve the quality of hearing in individuals who wear hearing aids.

Aim of this work was to assess the role of polymorphisms belonging to genes involved in the regulation of ionic homeostasis in Caucasian patients with Ménière Disease (MD) and compare results with a cohort of patients affected by vestibular migraine and a cohort of non vestibular subjects

Vertigo and dizziness are common neurological complaints in the emergency department and may represent a wide spectrum of etiologies, including vertebrobasilar transient neurological attacks (VB-TNAs). Distinguishing VB-TNAs, particularly vertebrobasilar transient ischemic attacks (VB-TIAs), from migraine-like and other non-vascular conditions is often challenging at first presentation due to the absence of specific biomarkers and overlapping clinical features. The UTRAVERA study is a multicenter, prospective, observational investigation designed to characterize the clinical features of patients presenting with acute transient vertigo or dizziness suspected to be VB-TNAs. The study will also evaluate diagnostic evolution over time, treatment responses, and prognostic factors associated with clinical outcomes.

Consultations for vertigo in general practice are difficult, primarily due to practitioners' lack of experience. Patient referrals can be inaccurate, leading to missed opportunities or misuse of resources. The creation of a diagnostic aid flowchart that provides referrals will improve patient care and reassure general practitioners during consultations for vertigo.

Background and Purpose: Vertigo is common in emergency and outpatient settings, yet standard oculomotor testing usually requires dedicated equipment and exam rooms. This study evaluates whether nystagmus examinations performed with wearable augmented-reality (AR) glasses are equivalent to conventional examination-room testing for classifying central vs. peripheral vertigo. The investigators also assess diagnostic accuracy, patient tolerability, and the reliability of AR-based interpretation (test-retest and inter-rater). Study Design: Prospective, single-center, within-subject randomized equivalence study at Kaohsiung Chang Gung Memorial Hospital. Each participant completes both AR-based and conventional oculomotor testing in a randomized order during the same visit, separated by a 30-minute washout. The study uses an evaluator-blind approach: de-identified trajectories are reviewed offline by independent experts who are masked to test modality. A follow-up visit (\~1 week) captures adverse events and patient experience. Participants: Adults (≥18 years) presenting with vertigo who can tolerate the AR headset and provide consent. Key exclusions include conditions that prevent reliable eye-tracking (e.g., corrected visual acuity \<20/40), recent use of vestibular suppressants (within 24 hours), and other factors limiting cooperation or safety. Interventions and Procedures: The AR system records eye movements and presents standardized visual stimuli. Conventional testing follows current clinical standards (e.g., Frenzel/oculomotor exam). All recordings are stored securely for blinded review. Outcomes: Primary endpoint: Equivalence of diagnostic agreement (central vs. peripheral) between AR-based and conventional methods, quantified by Cohen's kappa (κ) with a predefined equivalence margin. Secondary endpoints: (1) Diagnostic accuracy of the AR method in a clinically-indicated imaging subgroup (MRI preferred; CT as needed) using a sequential evaluation strategy; (2) Patient discomfort/tolerability using VAS and CSQ-VR, compared between modalities; (3) Test-retest reliability of AR-based classifications; (4) Inter-rater reliability between independent evaluators, with a third reader adjudicating discordant cases; (5) prespecified subgroup analyses by age, medical history, and vestibular function. Sample Size and Duration: Approximately 200 participants will be enrolled (target \~180 evaluable after \~10% attrition). Total study duration is \~2 years, including enrollment, follow-up, and analysis. Risks and Benefits: Both tests are non-invasive. Potential transient discomfort (e.g., eye strain or cybersickness) will be monitored. There may be no direct benefit to participants; however, results could support broader, more accessible, and standardized vertigo assessment. Data Security and Privacy: All data are de-identified, stored on secure platforms with role-based access and audit trails. Safety events are monitored and graded, and protocol deviations are handled per Good Clinical Practice.

Vertigo, dizziness, and imbalance are commonly reported by patients and technologists when near high-field strength magnets (\>4 Tesla, T) used for magnetic resonance imaging (MRI) (1-5) Prior research from the investigators has established that the mechanism is likely a Lorentz force occurring in the inner ear, as a result of interactions with normal electrical currents in the inner ear and the strong static magnetic field of the MRI machine. The investigators have recently developed preliminary data to suggest that slower rates of entry into the magnetic field can greatly attenuate the sensations of vertigo. The explanation for this is that the rates of vestibular adaptation exceed that of the stimulus, allowed a reduction or elimination of the symptoms of vertigo. The aim of this study is to recruit individuals who are already getting an MRI scan as part of other research studies to randomize the rate of entry into and exit from the static magnetic field (i.e., before and after imaging is performed). The usual rate of entry is 20 seconds. This will be increased to one, two or three minutes. The investigators will record subjective sensations of dizziness and vertigo associated with the entry into the MRI.

Vestibular migraine is a phenotype of migraine, characterized by more prominent vertigo symptoms compared to headache. Treatments for VM are mainly divided into two categories: acute treatment and preventive treatment. Acute treatment aims to reduce the severity and duration of a single episode, while preventive treatment aims to decrease the frequency, severity, and duration of attacks. Current acute treatments are primarily divided into pain relief and anti-dizziness, with specific drugs such as triptans and ergots being applicable for pain relief, but only betahistine has weak evidence for anti-dizziness, and relevant clinical evidence is very scarce. Preventive treatment mainly refers to migraine preventive treatments, with recommended medications including traditional drugs like topiramate, flunarizine, propranolol, etc., but the efficacy and safety of these drugs are limited. CGRP-targeted drugs are believed to play a role in the preventive treatment of VM, and there are related literature reports, but most are small-sample studies or retrospective studies. This study aims to explore the real-world efficacy of CGRP-targeted drugs in the acute and preventive treatment of VM through a prospective real-world study.

THIS STUDY IS A RANDOMIZED CONTROL TRIAL AND THE PURPOSE OF THE STUDY IS TO DETERMINE THE EFFECT OF WIIFIT TRAINING IN COMPARISON TO VESTIBULAR REHAB TRAINING ON BALANCE IN PATIENTS WITH BENIGN PAROXYSMAL POSITIONAL VERTIGO

BACKGROUND: A chief complaint of acute vertigo/dizziness is related to about 2.1-7.1% of all emergency department (ED) visits. About 25% of all patients with acute prolonged vertigo meeting diagnostic criteria of AVS (acute vestibular syndrome) suffer from a vertebrobasilar stroke and about 35% of these patients are initially missed. Differentiating dangerous central from more benign peripheral causes of AVS is essential. Subtle oculomotor paradigms such as HINTS (Head-Impulse, Nystagmus, Test-of-Skew) have been shown to detect central causes with high diagnostic accuracy, however, require sufficient training. Thus, identifying other bedside tests that can be reliably performed by frontline providers is essential to reduce misdiagnosis. WORKING HYPOTHESIS: By using additional oculomotor (saccades, pursuit) and pupillomotor parameters at the bedside or quantitatively, the diagnostic accuracy for distinguishing peripheral from central AVS causes can be further improved, especially in the setting when expertise for applying more sophisticated algorithms (HINTS(+), STANDING) is lacking. AIM 1: Detecting changes in oculomotor and pupillomotor responses in acutely dizzy patients and characterizing the spectrum of abnormalities in peripheral and central AVS. AIM 2: Comparing different composite oculomotor-/pupillomotor scores to identify those scores with the highest diagnostic accuracy at the bedside and quantitatively. AIM 3: Comparing the diagnostic accuracy of bedside and quantitative oculomotor and pupillomotor testing in AVS- identifying potential limitations of bedside testing. METHODS: To assess oculomotor and pupillomotor responses in patients with peripheral or central AVS and healthy controls (25 participants each) at the bedside and quantitatively by use of a Pioneer research eye tracker (PRET) system and to compare the diagnostic accuracy of individual and composite responses. EXPECTED VALUE OF THE PROJECT: The proposed project will shed more light on the value of different examination techniques in AVS for distinguishing peripheral from central causes. This is achieved by investigating oculomotor and pupillomotor parameters obtained at the bedside and quantitatively in the acute stage and at follow-up. The insights gained will likely have a direct impact on diagnostic accuracy and thus on future strategies how to evaluate acutely dizzy patients in the ED. Eventually, this may reduce the rate of misdiagnosis and may improve patients' outcome.

Vertigo is among the most prevalent disorder in older adults around the world leads to dizziness and balance problems resulting in decreased quality of life. Brandt daroff exercises can accelerate vertigo recovery and prevent recurrence without taking drugs. Cawthorne Cooksey first presented vestibular exercises to improve neurophysiological habituation, improves balance in the elderly. This study aims to determine the effects of brandt daroff exercises with cawthorne cooksey exercises on balance, dizziness and functional parameters in older adults with vertigo.

The main objective is to analyze the abnormality of physical condition, mental health and blood examination of the patients with benign paroxysmal positional vertigo (BPPV). Besides, the investigators aim to establish a database of BPPV based on multimodal magnetic resonance imaging data in the brain to identify high-risk patients with residual dizziness (RD) and systematically establish the comprehensive assessment system for the precise diagnosis, treatment and recovery of RD, optimize the tactics of BPPV management in China.
