Test-Retest Reliability of Repetitive Ocular Vestibular Evoked Myogenic Potentials in Myasthenia Gravis Patients and Healthy Control Subjects.

Purpose: Repetitive ocular vestibular evoked myogenic potentials (ROVEMP) are a novel diagnostic test to quantify neuromuscular transmission deficits in extraocular muscles in myasthenia gravis. We aimed to investigate the test-retest reliability of the ROVEMP and the effect of amplitude and age.

Methods: We performed the ROVEMP test twice in 19 patients with myasthenia gravis (52.

Paroxysmal localized Hyperhidrosis, a case-report: When excessive sweating occurs in combination with severe headaches.

Background: Paroxysmal localized hyperhidrosis is a rare disorder of the central autonomic nervous system. No association between paroxysmal hyperhidrosis and severe headache has been previously described in literature. A 65-year-old woman with idiopathic paroxysmal localized hyperhidrosis combined with severe holocranial headache attacks is described in this case report.

Neurovestibular Dysfunction and Falls in Parkinson's Disease and Atypical Parkinsonism: A Prospective 1 Year Follow-Up Study.

Our primary aim was to determine whether neurovestibular laboratory tests can predict future falls in patients with either Parkinson's disease (PD) or atypical parkinsonism (AP). We included 25 healthy subjects, 30 PD patients (median Hoehn and Yahr stage 2.5, range 1-4), and 14 AP patients (6 multiple system atrophy, 3 progressive supranuclear palsy, and 5 vascular parkinsonism) in a case-control study design (all matched for age and gender).

Static Subjective Visual Vertical in Healthy Volunteers: The Effects of Different Preset Angle Deviations and Test-Retest Variability.

The static subjective visual vertical (SVV) was assessed in 24 healthy volunteers with different preset angles (i.e., 10, 20, and 30 degrees), and in 20 other volunteers, the static SVV was tested and retested 1 week later.

Neurovestibular analysis and falls in Parkinson's disease and atypical parkinsonism.

The primary aim of our study was to determine the extent of vestibular dysfunction in patients with Parkinson's disease (PD). Our secondary aim was to determine if vestibular dysfunction in PD is a risk factor for falling. The tertiary aim was to determine both the extent of vestibular dysfunction and if this dysfunction is a risk factor for falling in patients with atypical parkinsonism (AP).
