OBJECTIVES: The video-head-impulse test (vHIT) provides a functional assessment of all six semicircular canals (SCC). Occasionally isolated loss of the posterior canal(s) (ILPC) is diagnosed, though this finding is poorly characterized. Here we assessed how accurate that diagnosis is by measuring the co-occurrence of abnormalities on caloric irrigation, vestibular-evoked myogenic-potentials and audiometry. METHODS: We identified 52 patients with ILPC (unilateral=40, bilateral=12)...

INTRODUCTION AND OBJECTIVES: The set of symptoms relating to disorders of the balance system are common in the general population. However, there are few studies quantifying the frequency of onset of the various vestibular disorders that present in specialist otoneurology units in the Spanish population. The aim of this study is to establish the epidemiology of vestibular disorders, their form of presentation, and the expected care burden in a specialist otoneurology clinic. MATERIAL AND METHODS: A retrospective, descriptive, observational study of patients referred to the otoneurology unit of a third level hospital between 1/1/2015 and 31/12/2015...

We sought to identify predictors of symptomatic recovery in vestibular neuritis. Forty VN patients were prospectively studied in the acute phase (median = 2 days) and 32 in the recovery phase (median = 10 weeks) with vestibulo-ocular reflex, vestibular-perceptual, and visual dependence tests and psychological questionnaires. Clinical outcome was Dizziness Handicap Inventory score at recovery phase. Acute visual dependency and autonomic arousal predicted outcome. Worse recovery was associated with a combination of increased visual dependence, autonomic arousal, anxiety/depression, and fear of bodily sensations, but not with vestibular variables...

Controversy still surrounds both the etiology and pathophysiology of vestibular neuritis (VN). Especially uncertain is why the superior vestibular nerve (SVN) is more frequently affected than the inferior part (IVN), which is partially or totally spared. To address this question we developed an improved method for preparing human vestibular ganglia (VG) and nerve. Subsequently macro- and micro-anatomical as well as PCR studies were performed on 38 human ganglia from 38 individuals. The SVN was 2.4 mm longer than the IVN, and in 65% of the cases the IVN ran in two separate bony canals, which was not the case for the SVN...

The aim of this study was to establish the effect of vestibular lesion on vestibular imagery. Subjects were required to estimate verbally their passively travelled rotation angles in complete darkness, i.e., to activate vestibular imagery. During motion, the vestibulo-ocular reflex (VOR) was measured. Thus, we examined the coherence between the vestibulo-ocular reflex and self-rotation imagery, with vestibular-lesioned patients and healthy participants. Unilateral acute and chronic patients, bilateral patients, and healthy subjects were compared...

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...

In response to passive high-acceleration head impulses patients with low vestibulo-ocular reflex (VOR) gains often produce covert (executed while the head is still moving) corrective saccades in the direction of deficient slow phases. Here we examined 23 patients using passive, and nine also active, head impulses with acute (< 10 days from onset) unilateral vestibular neuritis and low VOR gains. We found that when corrective saccades are larger than 10°, the slow-phase component of the VOR is inhibited, even though inhibition increases further the time to reacquire the fixation target...

: 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...
