Vestibular migraine is among the commonest causes of episodic vertigo. Chronically, patients with vestibular migraine develop abnormal responsiveness to both vestibular and visual stimuli characterized by heightened self-motion sensitivity and visually-induced dizziness. Yet, the neural mechanisms mediating such symptoms remain unknown. We postulate that such symptoms are attributable to impaired visuo-vestibular cortical interactions, which in turn disrupts normal vestibular function. To assess this, we investigated whether prolonged, full-field visual motion exposure, which has been previously shown to modulate visual cortical excitability in both healthy individuals and avestibular patients, could disrupt vestibular ocular reflex and vestibular-perceptual thresholds of self-motion during rotations...

Dizziness is a common chief complaint with an extensive differential diagnosis that includes both benign and serious conditions. Physicians must distinguish the majority of patients who suffer from self-limiting conditions from those with serious illnesses that require acute treatment. The preferred approach to the diagnosis of an acutely dizzy patient emphasizes different aspects of the history to guide a focused physical examination, with the goal of differentiating benign peripheral vestibular conditions from dangerous posterior circulation strokes...

PURPOSE: There is little knowledge on how neck pain impacts dizzy patients, and if different diagnoses of dizziness associate with neck pain. The aim was to examine differences in dizziness severity, quality of life and demographics in dizzy patients with and without neck pain. Additionally, we examined if neck pain was associated with a non-vestibular or vestibular diagnosis. METHODS: We included 236 consecutive patients referred to an otorhinolaryngological university clinic for vertigo and balance problems...

BACKGROUND: Stroke mimics (SMs)are medical conditions that are at first considered to be of cerebrovascular etiology but turn out to be a condition other than stroke. While many reports on SMs have been published, there have been none from Japan. Thus, we sought to assess the current state of SMs in a Japanese population. METHODS: We collected data of patients referred with suspicion of stroke to neurosurgeons by emergency department (ED) doctors, and we retrospectively evaluated the diagnosis concordance rate between the ED doctors and the neurosurgeons...

BACKGROUND: Vertigo is a common symptom of multiple sclerosis (MS) that can be caused by a central or peripheral involvement of the vestibular pathways. Magnetic Resonance Imaging (MRI) is commonly used to evaluate progression of MS but is not sensitive enough to detect small lesions. Vestibular evoked myogenic potentials (VEMPs) are commonly used to evaluate function of vestibular-cochlear pathways. The aim of this literature review is to evaluate the role of VEMPs in patients with MS-related vertigo as a tool to detect demyelinating lesions in the vestibular pathways of MS patients and to monitor MS progression...

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and accounts for 8% of individuals with moderate or severe dizziness. BPPV patients experience substantial inconveniences and disabilities during symptomatic periods. BPPV therapeutic processes - the Dix-Hallpike Test (DHT) and the Canalith Repositioning Maneuver (CRM) - have an evidence base that is at the clinical practice guideline level. The most commonly used CRM is the modified Epley maneuver...

PURPOSE OF REVIEW: To provide an update on the most frequent peripheral vestibular disorders. RECENT FINDINGS: The on-going classification of vestibular disorders by the Bárány Society represents major progress. The diagnosis of bilateral vestibulopathy (BVP) requires quantitative testing of vestibular function. 'Acute unilateral peripheral vestibulopathy' (AUPVP) is now preferred over 'vestibular neuritis.' Menière's disease is a set of disorders with a significant genetic contribution...

Benign paroxysmal positional vertigo (BPPV) is the most common cause of balance disorders in the elderly. Dislodgement of the otoconia in BPPV might have an association with damage to the otolith organs. The aim of this study was to investigate whether aging is a risk factor for otolith organ dysfunction in idiopathic BPPV. We retrospectively reviewed the medical records of 112 consecutive idiopathic BPPV patients who underwent cervical VEMP testing to air-conducted sound (ACS cVEMP), ocular VEMP testing to bone-conducted vibration (BCV oVEMP), and caloric testing...

Botulism is a serious illness caused by exposure to botulinum toxin. It is manifested by flaccid, paralysis, symmetric and in descending pattern affecting cranial and peripheral nerves. Given the frequent need for invasive mechanical ventilation, these patients should be approached in an intensive care setting. Treatment with anti-botulinum toxin is the only effective treatment. The authors present the case of a 64-year-old patient, with vomiting and vertigo, evolution to diplopia, dysphagia and flaccid, muscle paralysis, installation after ingestion of canning homemade...

Objectives: Direction-changing positional nystagmus (PN) was considered to indicate the presence of benign paroxysmal positional vertigo involving lateral semicircular canal in most cases. We investigated the incidence of PN on the supine head-roll test and compared the characteristics of nystagmus in patients with vestibular neuritis (VN) and Meniere disease (MD). Methods: A retrospective review of patients, who were diagnosed with unilateral VN or unilateral definite MD between September 2005 and November 2011, was conducted...

Vertigo is defined as an abnormal sensation of body motion or of its surrounding objects. It is a common chief complaint in emergency departments comprising 2 to 3% of these consultations worldwide. Vertigo is classified as peripheral or central, according to its origin, and can also be occasionally mixed, the most common cause of peripheral involvement being benign paroxysmal positional vertigo. The initial findings on clinical evaluation of patients are the clues for making a correct diagnosis. The differentiation between central and peripheral vertigo can be optimized by analysing nystagmus, by using the skew test and the head impulse test (HINTS), as also by performing the appropriate tests to evaluate the integrity of the vestibular-cerebellar pathway...

The assessment and treatment of sport-related concussion (SRC) often requires a multifaceted approach. Vestibular dysfunction represents an important profile of symptoms and pathology following SRC, with high prevalence and association with prolonged recovery. Signs and symptoms of vestibular dysfunction may include dizziness, vertigo, disequilibrium, nausea, and visual impairment. Identifying the central and peripheral vestibular mechanisms responsible for pathology can aid in management of SRC. The most common vestibular disturbances after SRC include benign paroxysmal positional vertigo, vestibulo-ocular reflex impairment, visual motion sensitivity, and balance impairment...
