OBJECTIVE: Vestibular dysfunction is a well-recognized complication of type 2 diabetes (DM) that may contribute to increased fall risk. The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with DM. The impact of DM on the otolith organs of the vestibular system in people with BPPV is unknown. The purpose of this study was to analyze otolith function using vestibular-evoked myogenic potential (VEMP) tests in people with DM and concurrent BPPV (BPPV + DM), and to examine the relationships between VEMP variables and diabetes-related variables...

CONCLUSION: The Li maneuver is a safe, effective, and simple repositioning method for the treatment of BPPV. It is simple to master and exerts an exact effect. As a rapid repositioning method, the Li maneuver can result in reduced treatment times and increased treatment efficacy, and is, therefore, especially suitable for patients with limited cervical spine movement. OBJECTIVE: To compare the short-term efficacies of the Li and Epley maneuvers in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV)...

CONCLUSION: Elevated Motion Sickness Susceptibility (MSS) in Meniere?s disease (MD) is likely to be a consequence of the onset of MD and not migraine per se. OBJECTIVES: Pathologies of the vestibular system influence MSS. Bilateral vestibular deficits lower MSS, vestibular neuritis or benign paroxysmal positional vertigo have little overall effect, whereas vestibular migraine elevates MSS. However, less is known about MSS in MD, a condition in which many patients experience vestibular loss and migraine symptoms...

BACKGROUND: Positional compression of the vertebral artery (VA) due to cervical spondylosis is an uncommon cause of stroke. We report two cases of cervical spondylosis causing wake-up stroke, which is extremely rare. CASE DESCRIPTION: The first case was a 78-year-old woman who presented with vertigo and vomiting lasting from waking up. Magnetic resonance (MR) images and angiography documented right cerebellar infarction, and stenosis of the right cervical VA. Dynamic angiography revealed that the right VA was occluded when her neck was extended or rotated to the right...

The Le Fort I osteotomy is widely used to correct dentofacial deformities. Benign paroxysmal positional vertigo (BPPV) is a common vestibular end organ disorder characterized by short, often recurrent episodes of vertigo. Head trauma is one of the known causes of BPPV. During pterygoid osteotomy, the surgical trauma induced by percussion with the surgical mallet and osteotomes can displace otoliths into the semicircular canal, resulting in BPPV. The aim of this study was to evaluate the potential risk of occurrence of BPPV in individuals undergoing Le Fort I osteotomy...

Vertigo and dizziness are with an annual incidence of more than 10% and a lifetime prevalence of more than 30% among the most frequent symptoms. The keys to the diagnosis are the patient history and the bedside examination: a) for the patient history the time course, type and triggers of symptoms and accompanying symptoms, b) for the clinical examination of the vestibular system the head-impulse test (HIT), the examination for a spontaneous nystagmus, a displacement of subjective visual vertical, a positional nystagmus and the Romberg test, and c) for the differentiation between an acute peripheral and central vestibular lesion the skew deviation, central fixation nystagmus, gaze-evoked nystagmus, saccadic smooth pursuit and a normal HIT...

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). We recruited 155 patients with definite Ménière Disease and 186 controls (Control Group 1) without a lifetime history of vertigo, overlapping with patients for age and rate of hypertension. We validated the positive results on 413 Caucasian subjects selected from a European general population (Control Group 2). The clinical history for migraine and hypertension was collected; genomic DNA was characterized for a panel of 33 SNPs encoding proteins involved in ionic transport...

OBJECTIVE: Although there has been a wide consensus on the mechanism of nystagmus and clinical presentation of benign paroxysmal positional vertigo (BPPV), the neuroepithelial pathophysiology of BPPV still remains unclear. In this study, we aimed to clarify the pathophysiology of BPPV by evaluating the cervical vestibular-evoked myogenic potential (cVEMP) findings of patients. MATERIALS AND METHODS: Thirty-six BPPV patients and 20 healthy volunteers were included...

CONCLUSION: Patients with BPPV experienced short but intense anxiety and/or panic disorder, especially at the initial visit, but most patients recovered without medication with successful treatment. OBJECTIVE: Recent studies have shown that people with dizziness report some psychological problems such as panic and agoraphobia and anxiety. The aim of this study was to evaluate anxiety and panic agorophobia levels in patients with benign paroxysmal positional vertigo on initial presentation and at the follow-up visit and compare the scores with the control group...

We herein present a rare case of bilateral positional vertebrobasilar insufficiency secondary to mechanical obstruction of the V2 segment of the vertebral artery in a 71-year-old patient presenting with vertigo, occipital headache, tremors and respiratory irregularities. Two-dimensional digital subtraction angiography is the traditional diagnostic imaging standard but does not capture any peri-vascular bony or soft tissue abnormalities that are important to understand the three-dimensional pathophysiology. Intra-procedural cone-beam computed tomography (CT) is an increasingly used diagnostic adjunct, available in most modern angiographic suites that allows for the three-dimensional visualization of the vasculature as well as CT-like soft tissue visualization of its surrounding anatomy...
