REVIEW
Thomas Brandt, Marianne Dieterich
Vertigo and dizziness are among the most common complaints in neurology clinics, and they account for about 13% of the patients entering emergency units. In this Review, we focus on central vestibular disorders, which are mostly attributable to acute unilateral lesions of the bilateral vestibular circuitry in the brain. In a tertiary interdisciplinary outpatient dizziness unit, central vestibular disorders, including vestibular migraine, comprise about 25% of the established diagnoses. The signs and symptoms of these disorders can mimic those of peripheral vestibular disorders with sustained rotational vertigo...

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral-type vertigo in the elderly. While some studies have investigated BPPV among the elderly, no study has focused on the isolated idiopathic BPPV (iBPPV) in the elderly. AIMS: To investigate the clinical features and recurrence rate in elderly patients diagnosed with iBPPV. METHODS: The authors prospectively reviewed the medical records of 627 patients diagnosed with BPPV, and a total of 370 patients fulfilled the inclusion criteria...

Vestibular neuritis is one of the most common peripheral causes of acute vestibular syndrome, of which the diagnosis is generally based on a comprehensive interpretation of clinical and laboratory findings following reasonable exclusion of other disorders. This study aimed to investigate the final diagnosis of patients admitted to hospital under the clinical impression of vestibular neuritis who showed no unilateral caloric paresis. Forty-five patients who visited the emergency department with isolated acute spontaneous vertigo were included...

This study investigated the relationship among the severity of hearing impairment, vestibular function and balance function in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). A total of 35 ISSNHL patients (including 21 patients with vertigo) were enrolled. All of the patients underwent audiometry, sensory organization test (SOT), caloric test, cervical vestibular-evoked myogenic potential (cVEMP) test and ocular vestibular-evoked myogenic potential (oVEMP) test. Significant relationship was found between vertigo and hearing loss grade (P=0...

AIM: The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with type 2 diabetes (DM). The impact of DM on mobility, balance, and management of BPPV is unknown. This prospective study compared symptom severity, mobility and balance before and after the canalith repositioning maneuver (CRM) in people with posterior canal BPPV canalithiasis, with and without DM. METHODS: Fifty participants, BPPV (n=34) and BPPV+DM (n=16) were examined for symptom severity (dizziness handicap inventory, DHI), mobility (functional gait assessment, FGA), and postural sway (using an accelerometer in five conditions) before and after the CRM...

BACKGROUND AND PURPOSE: Diabetes has been shown to affect the peripheral vestibular end organs and is associated with an increase in the frequency of benign paroxysmal positional vertigo (BPPV). People with diabetes have higher postural sway; however, the impact of symptomatic BPPV on postural sway in individuals with diabetes is unclear. The purpose of this cross-sectional study was to examine postural sway in people with type 2 diabetes who have symptomatic, untreated BPPV (BPPVDM)...

The acute vestibular syndrome is a clinically defined entity consisting of vertigo or dizziness that develops acutely over minutes to hours and is accompanied by nausea/vomiting, gait instability, head motion intolerance, and nystagmus, while persisting over a day or more. When it is caused by a peripheral vestibular lesion and is not associated with clinically manifest auditory deficits, it is mostly labeled vestibular neuritis/neuronitis/neuropathy or sometimes peripheral vestibulopathy. Here, we propose hypotheses and discuss current research advances on viral or vascular factors in the pathogenesis, the recurrence, the site of lesion, old and new treatment options, contraindicated measures, the differential diagnosis, and the prognosis of vestibular neuritis/neuronitis/neuropathy or vestibulopathy...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is a common type of vertigo caused by the peripheral vestibular system. The majority of cases are accepted as idiopathic. Calcium metabolism also plays a primary role in the synthesis/absorption of otoconia made of calcium carbonate and thus might be an etiological factor in the onset of BPPV. In this study, we aimed to investigate the role of osteoporosis and vitamin D in the etiology of BPPV by comparing BPPV patients with hospital-based controls...

BACKGROUND: The primate ocular motor system is designed to acquire peripheral targets of interest by coordinating visual, vestibular, and neck muscle activation signals. The vestibulo-ocular reflex (VOR) is greatly reduced at the onset of large eye-head (gaze) saccades and resumes before the end of the saccades to stabilize eye-in-orbit and ensure accurate target acquisition. Previous studies have relied on manipulating head movements in normal individuals to study VOR suppression and gaze kinematics...

Dizziness is a common yet imprecise symptom. It was traditionally divided into four categories based on the patient's history: vertigo, presyncope, disequilibrium, and light-headedness. However, the distinction between these symptoms is of limited clinical usefulness. Patients have difficulty describing the quality of their symptoms but can more consistently identify the timing and triggers. Episodic vertigo triggered by head motion may be due to benign paroxysmal positional vertigo. Vertigo with unilateral hearing loss suggests Meniere disease...

BACKGROUND: Fusiform aneurysms in the posterior inferior cerebellar artery (PICA) are rare and challenging to treat. Surgical treatment options for a fusiform aneurysm in the PICA include trapping with/without bypass and wrap-clipping, when elimination of the pathological wall from the systemic circulation and prevention of perforator injury are important. In addition, lower cranial nerve impairment due to surgical manipulation should also be avoided. METHOD: A fusiform-shaped aneurysm was found in a proximal part of the PICA by magnetic resonance angiography undertaken for evaluation of repeated vertigo in a 36-year-old man...

PURPOSE: Positional nystagmus is usually caused by peripheral vestibular disorder, mostly benign paroxysmal positional vertigo (BPPV). However, positional nystagmus is also encountered in central lesions. We aimed to determine clinical characteristics of the structures responsible for central positional nystagmus (CPN) associated with brain tumors. METHODS: All four patients (3 men; range=19-77years) had an evaluation of spontaneous and positional nystagmus using video-oculography...

INTRODUCTION: Dizziness is a common symptom in general practice with a high prevalence among older adults. The most common cause of dizziness in general practice is peripheral vestibular disease. Vestibular rehabilitation (VR) is a safe and effective treatment for peripheral vestibular disease that entails specific exercises to maximise the central nervous system compensation for the effects of vestibular pathology. An internet-based VR intervention has recently been shown to be safe and effective...

Vertigo and dizziness are extremely common complaints, related to either peripheral or central nervous system disorders. Among the latter, epilepsy has to be taken into consideration: indeed, vertigo may be part of the initial aura of a focal epileptic seizure in association with other signs/symptoms, or represent the only ictal manifestation, a rare phenomenon known as "vertiginous" or "vestibular" seizure. These ictal symptoms are usually related to a discharge arising from/involving temporal or parietal areas, which are supposed to be a crucial component of the so-called "vestibular cortex"...
