Human eye fixation is steadily interrupted by small, physiological or abnormal, movements. Square-wave jerks (SWJ) are the most common saccadic intrusion which can be readily seen at bedside and also quantified using oculographic techniques. Various neurological, neuropsychiatric psychiatric disorders display abnormal fixational movement patterns characterized frequent SWJ. For clinician, SWJ particularly important because they observed bedside. Here, we will discuss pathological conditions...
Abstract Introduction Persistent Postural-Perceptual Dizziness (PPPD), as an umbrella term for functional dizziness, encompasses a wide range of subjective symptoms affecting visual, vestibular, and motor functions. We developed the Athens-Lübeck Questionnaire (ALQ) bedside tool to differentiate specific symptom subtypes, which could inform more targeted research into pathogenesis syndrome facilitate tailored physiotherapeutic interventions. Methods A total 96 patients with primary or...

Our subjective sense-of-direction is influenced by how good we are at spatial navigation using vestibular cues. Global positioning systems (GPS) may inhibit sense of direction. Increased use GPS the young explain why elderly’s direction not worse than young’s. Patients with vestibulo-cerebellar dysfunction (downbeat nystagmus syndrome) display normal navigation, suggesting that ascending vestibulo-cerebellar-cortical pathways carry velocity rather position signals. Pilot data indicate...
Introduction: Previous epidemiological evidence has established the co-occurrence of malignant melanoma (MM) and Parkinson’s disease (PD). Shared molecular mechanisms have been proposed to be implicated in this relationship. The aim present study was assess prevalence MM patients with sporadic genetic types PD, as well asymptomatic carriers PD-related genes. Methods: Data regarding past medical history concomitant 1416 PD (including 20 participants prodromal who phenoconverted PD), 275...
Previous studies in phobic postural vertigo patients showed characteristic frequency changes body sway fluctuations, raising the question whether similar spectral can be also observed recently defined syndrome of persistent postural-perceptual dizziness (PPPD).Cross-sectional prospective study.Tertiary referral center.Sixty-one PPPD and 41 healthy controls.Static balance was assessed while standing on firm surface with eyes open or closed (conditions 1 2) foam 3 4). Postural analyzed by...
Abstract Monocular torsional eye oscillations are a rare form of disconjugate nystagmus and the underlying pathophysiology is not well understood. Here, we present discuss case with disabling oscillopsia in one only. The patient exhibited spontaneous pendular left rhythmic involuntary movements soft palate uvula, consistent syndrome oculopalatal tremor monocular nystagmus. Brain MRI revealed an infarct dentate nucleus cerebellum and, more caudally, secondary hypertrophic degeneration right...
