Vascular vertigo and dizziness: Diagnostic criteria.

This paper presents diagnostic criteria for vascular vertigo and dizziness as formulated by the Committee for the Classification of Vestibular Disorders of the Bárány Society. The classification includes vertigo/dizziness due to stroke or transient ischemic attack as well as isolated labyrinthine infarction/hemorrhage, and vertebral artery compression syndrome. Vertigo and dizziness are among the most common symptoms of posterior circulation strokes.

Persistent Postural-Perceptual Dizziness: Precipitating Conditions, Co-morbidities and Treatment With Cognitive Behavioral Therapy.

Persistent postural perceptual dizziness (PPPD) is a common chronic vestibular disorder characterized by persistent vestibular symptoms, including postural instability and non-spinning vertigo, which is aggravated by motion, upright posture and moving or complex visual stimuli. In our review of 198 cases seen over a 5 year period, we have confirmed a number of common precipitating conditions for PPPD, including anxiety disorders and vestibular migraine. Vestibular abnormalities, including a unilateral loss of vestibular hypofunction and isolated otolith abnormalities, were found on investigation in just under half the cases.

Vestibular migraine: Diagnostic criteria1.

This paper presents diagnostic criteria for vestibular migraine, jointly formulated by the Committee for Classification of Vestibular Disorders of the Bárány Society and the Migraine Classification Subcommittee of the International Headache Society (IHS). It contains a literature update while the original criteria from 2012 were left unchanged. The classification defines vestibular migraine and probable vestibular migraine.

Genetic prion disease: D178N with 129MV disease modifying polymorphism-a clinical phenotype.

Background: Human prion diseases are a group of rare neurological diseases with a minority due to genetic mutations in the prion protein (PRNP) gene. The D178N mutation is associated with both Creutzfeldt-Jakob disease and fatal familial insomnia with the phenotype modified by a polymorphism at codon 129 with the methionine/valine (MV) polymorphism associated with atypical presentations leading to diagnostic difficulty.

Case: We present a case of fatal familial insomnia secondary to a PRNP D178N mutation with 129MV disease modifying polymorphism who had no family history, normal MRI, electroencephalography (EEG), cerebrospinal fluid (CSF) and positron emission tomography findings and a negative real-time quaking-induced conversion result.

HaNDL with bilateral central venous occlusions.

Background: The syndrome of Headache and focal Neurological Deficits with cerebrospinal fluid Lymphocytosis (HaNDL) is considered a rare, idiopathic and self-limited condition.

Methods: We present a patient with HaNDL who had unique findings of florid optic disc haemorrhages from bilateral central retinal vein occlusions.

Results: Our patient made a full recovery with conservative management.

Importance of spontaneous nystagmus detection in the differential diagnosis of acute vertigo.

Vertigo is a common cause of emergency department attendance. Detection of spontaneous nystagmus may be a useful sign in distinguishing vestibular neuritis from other vestibular diagnoses. We aimed to assess the contribution of spontaneous nystagmus in the diagnosis of acute vertigo.

Vestibular migraine: diagnostic criteria.

This paper presents diagnostic criteria for vestibular migraine, jointly formulated by the Committee for Classification of Vestibular Disorders of the Bárány Society and the Migraine Classification Subcommittee of the International Headache Society (IHS). The classification includes vestibular migraine and probable vestibular migraine. Vestibular migraine will appear in an appendix of the third edition of the International Classification of Headache Disorders (ICHD) as a first step for new entities, in accordance with the usual IHS procedures.

Two patients with audiovestibular sarcoidosis.

We report two patients with biopsy-proven audiovestibular sarcoidosis who presented with hearing loss, vertigo and gait ataxia. Oto-neurological investigations confirmed the presence of sensorineural hearing loss, vestibular hypofunction and abnormal auditory brainstem responses. MRI scans of the brain revealed enhancement of the vestibulo-cochlear nerves.

Cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS): a review of the clinical features and video-oculographic diagnosis.

The association of bilateral vestibulopathy with cerebellar ataxia was first reported in 1991 and delineated as a distinct syndrome with a characteristic and measurable clinical sign--an absent visually enhanced vestibulo-ocular reflex--in 2004. We reviewed 27 patients with this syndrome and show that a non-length-dependent sensory deficit with absent sensory nerve action potentials is an integral component of this syndrome, which we now call "cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome" (CANVAS). All patients had brain MRI and 22/27 had evidence of cerebellar atrophy involving anterior and dorsal vermis, as well as the hemispheric crus I.

Vertebrobasilar ischaemia presenting as recurrent isolated vertigo.

Chronic recurrent isolated vertigo is an uncommon manifestation of vertebrobasilar ischaemia. We report a 43-year-old female with 12-month history of recurrent attacks of isolated vertigo who presented with acute pontine infarctions. Clinical examination and vestibular function testing showed bilateral vestibular hypofunction affecting the horizontal and posterior semicircular canals and right saccule.

Does otolith organ dysfunction influence outcomes after a customized program of vestibular rehabilitation?

Background And Purpose: Vestibular rehabilitation (VR) is a successful approach to the treatment of vestibular dysfunction. The purpose of this study was to investigate the influence of otolith dysfunction on the response to VR in individuals with a peripheral vestibular disorder.

Participants And Methods: Eighteen participants with loss of semicircular canal function only, and 29 participants with combined loss of semicircular canal and otolith organ function were recruited.

The influence of otolith dysfunction on the clinical presentation of people with a peripheral vestibular disorder.

Background And Purpose: Traditional vestibular function testing has measured horizontal semicircular canal function only. Otolith function tests have recently been developed, but their clinical significance has not been determined. The purpose of this study was to investigate the influence of otolith dysfunction on the clinical presentation of individuals with a peripheral vestibular disorder.

A pilot study of falls risk and vestibular dysfunction in older fallers presenting to hospital emergency departments.

Purpose: To compare falls risk in older fallers and non-fallers, with an emphasis on dizziness and signs of vestibular dysfunction.

Method: The fallers had presented to the Emergency Department of the Royal Melbourne Hospital, Australia following a fall and were discharged directly home (n = 20) (75% female, mean age 78 years). The non-fallers were an age and gender matched group, who had not fallen in the past 12 months (n = 20).

Chronic migrainous vertigo.

A series of 16 subjects is described who presented with chronic vertigo that was thought to be migrainous in nature. The vertigo occurred on a daily basis and had been present for six months or more. Common symptoms included motion-induced dizziness, positional vertigo and motion sensitivity.
