Cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome (CANVAS) is a novel ataxic disorder consisting of the triad of cerebellar impairment, bilateral vestibular hypofunction, and a somatosensory deficit. We report the first Japanese case of CANVAS. The patient is a 68-year-old Japanese male. He was referred to our university for further evaluation of progressive gait disturbance and ataxia. He exhibited horizontal gaze-evoked nystagmus and sensory deficit. Nerve conduction studies showed sensory neuronopathy...

PURPOSE OF REVIEW: This review considers recent advances in central vertigo in terms of clinical and laboratory features and pathophysiology. RECENT FINDINGS: Strokes presenting dizziness-vertigo are more likely to be associated with a misdiagnosis in the emergency setting. The risk of future strokes after discharge is higher in patients diagnosed with peripheral vertigo than in control patients. Strokes and transient ischemic attacks account for one-quarter of acute transient vestibular syndrome...

This paper describes the diagnostic criteria for bilateral vestibulopathy (BVP) by the Classification Committee of the Bárány Society. The diagnosis of BVP is based on the patient history, bedside examination and laboratory evaluation. Bilateral vestibulopathy is a chronic vestibular syndrome which is characterized by unsteadiness when walking or standing, which worsen in darkness and/or on uneven ground, or during head motion. Additionally, patients may describe head or body movement-induced blurred vision or oscillopsia...

OBJECTIVE: It has long been suggested that antivertiginous medications exert their symptomatic effect through inhibition of the vestibulo-ocular reflex (VOR). We tested this hypothesis by directly measuring the VOR after administration of three agents from different substance classes: an antihistamine, a benzodiazepine and a calcium channel antagonist. METHODS: The gain and the variability of the high velocity VOR was assessed using video head impulses (vHIT) under the following conditions: baseline, after dimenhydrinate, after diazepam and after cinnarizine...

Patients with bilateral vestibular failure (BVF) suffer from postural and gait unsteadiness with an increased risk of falls. The aim of this study was to elucidate the differential role of otolith, semicircular canal (SSC), visual, proprioceptive, and cognitive influences on the postural stability of BVF patients. Center-of-pressure displacements were recorded by posturography under six conditions: target visibility; tonic head positions in the pitch plane; horizontal head shaking; sensory deprivation; dual task; and tandem stance...

Tandem gait testing is an integral part of the neurological exam. It is informative in a wide variety of disorders ranging from cerebellar disease to vestibular and peripheral neuropathies, parkinsonism, and other neurodegenerative conditions. We discuss the history and development of tandem gait testing as well as its technique, utility, and limitations in the assessment of neurological conditions. Tandem gait has emerged as a tool in the assessment of cerebellar disease, Huntington disease, idiopathic Parkinson's disease, atypical parkinsonism, peripheral neuropathies, and vestibulopathies...

Gentamicin, which is still used in modern medicine, is a known vestibular toxic agent, and various degrees of balance problems have been observed after exposure to this pharmacologic agent. Photobiomodulation is a candidate therapy for vertigo due to its ability to reach deep inner ear organs such as the cochlea. Previous reports have suggested that photobiomodulation can improve hearing and cochlea function. However, few studies have examined the effect of photobiomodulation on balance dysfunction. We used a rat model to mimic human vestibulopathy resulting from gentamicin treatment and evaluated the effect of photobiomodulation on vestibular toxicity...

BACKGROUND: Bilateral vestibulopathy (BVP) is a debilitating condition characterized by gait ataxia, oscillopsia, and imbalance. OBJECTIVE: Case series of patients with migraine-linked vertigo spells and profound BVP. PATIENT 1:: A 69-year-old man presented with a history of recurrent severe vertigo spells lasting up to 3 days in duration associated with prostrating migraine headaches starting at age 60. His symptoms were misdiagnosed as an anxiety syndrome. At age 68, electronystagmography (ENG) revealed bilaterally absent caloric responses and complete BVP...

Vestibular rehabilitation using individualized vibrotactile neurofeedback training (IVNT) can lead to significant improvement in the postural stability of patients with vestibular symptoms of different origins. However, some of these patients have complex, severe dizziness, meaning that a pharmacological pretreatment or parallel (to vestibular rehabilitation) treatment can help them perform the rehabilitation exercises. Hence, the present study investigated the influence of a pharmacological treatment on the efficacy of vibrotactile neurofeedback training in patients with chronic, noncompensated vestibulopathies...

OBJECTIVE: To characterize the stability limits and region in patients with unilateral vestibulopathy according to the side of the lesion and determine if that imposes any bias. To analyze if the stability limits and region depend on the functional deficit as evaluated in the sensory organization test. METHODS: Forty patients with chronic dizziness and without any vertigo spell for least 6 months prior to testing. In all of them, a unilateral vestibulopathy was diagnosed clinically and at vestibular testing...

REVIEW
Benjamin Kwok-Tung Tsang, Alex Siew-Kar Chen, Mark Paine
This review article aims to provide an evidence-based approach to evaluating the patient who presents with acute prolonged, spontaneous vertigo in the context of the acute vestibular syndrome (AVS). Differentiation of posterior circulation stroke presenting as an acute vestibular syndrome has been regarded as an important diagnostic challenge for physicians involved in acute care. Current evidence suggests that a targeted approach to history taking and physical examination with emphasis on the oculomotor examination, more specifically the HINTS (Head Impulse/ Nystagmus/Test-of-skew) examination battery, yields a higher sensitivity for diagnosis of posterior circulation stroke than even standard magnetic resonance imaging with diffusion weighted imaging...

Rehabilitation for vestibular disease is a safe method to partially alleviate symptoms of vertigo. It was hypothesized that principles of military aviation vestibular desensitization procedures that have a success rate of more than 80% can be extrapolated to chronic vestibular disease as well.The virtual reality motion base computer-assisted rehabilitation environment was used as treatment modality in 17 patients. They were exposed to sinusoidal vertical passive whole body motion in increasing intensity for a maximum of 12 sessions...

OBJECTIVE: To report an unusual lateral medullary stroke (LMS) associated with transient unidirectional horizontal, nystagmus, and decreased horizontal vestibulo-ocular reflex (h-VOR) gain that mimicked a peripheral vestibulopathy. MRI suggested involvement of caudal medial vestibular nucleus (MVN); however, the rapid resolution of the nystagmus and improved h-VOR gain favored transient ischemia without infarction. Decreased h-VOR gain is expected with peripheral vestibular lesions within the labyrinth or superior vestibular nerve; less frequently lateral pontine strokes involving the vestibular root entry, the vestibular fascicle, or neurons within the MVN may be responsible...

INTRODUCTION: Neurosyphilis producing basal meningitis presenting as sequential transient cranial nerve palsies was well recognized before the antibiotic era. OBJECTIVE: To report two patients presenting with acute unilateral peripheral vestibulopathy due to syphilitic basal meningitis. RESULTS: In Case 1 basal meningitis occurred early in the secondary phase of the infection, in Case 2 in the late latent phase. The diagnosis was not made immediately in either case; in Case 1 after previous presentation with increasing hearing loss and then with facial palsy and then a subsequent presentation with optic neuritis; in Case 2 after investigation for possible lymphoma...

We describe the case of a 34-year-old patient presenting with the unique combination of bilateral vestibulopathy in combination with noise- and pressure-induced nystagmus. Bilateral vestibular dysfunction was demonstrated by pathological results in video-based head impulse testing as well as in caloric testing. In contrast, cervical vestibular-evoked myogenic potentials were normal, demonstrating normal sacculus function. Due to the positive Tullio phenomenon, semicircular dehiscence syndrome was excluded. Recently, this symptom combination was related to the histopathological finding of vestibular atelectasis...
