THIS PAPER IS FOCUSED ON ONE MAJOR ASPECT OF COMPENSATION: the recent measures of saccadic responses to high acceleration head turns during human vestibular compensation and their possible implications for recovery after unilateral vestibular loss (UVL). New measurement techniques have provided additional insights into how patients recover after UVL and have given clues for vestibular rehabilit...

BACKGROUND AND PURPOSE To define the detailed spectrum of audiovestibular dysfunction in anterior inferior cerebellar artery territory infarction. METHODS Over 8.5 years, we prospectively identified 82 consecutive patients with anterior inferior cerebellar artery territory infarction diagnosed by MRI. Each patient completed a standardized audiovestibular questionnaire and underwent a neuro-ot...

Ethanol affects many parts of the nervous system, from the periphery to higher cognitive functions. Due to the established effects of ethanol on vestibular and oculomotor function, we wished to examine its effect on two new tests of the vestibulo-ocular reflex (VOR): the video head impulse test (vHIT) and dynamic visual acuity (DVA). We tested eight healthy subjects with no history of vestibula...

BACKGROUND AND OBJECTIVES ACCORDING TO PREVIOUS REPORTS, PATIENTS WITH VESTIBULAR MIGRAINE (VM) DISPLAY VARIABLE RESULTS FROM VESTIBULAR FUNCTION TESTS (VFT): central, peripheral, or normal. The aim of this study was to classify the VM patients into the three groups according to interictal VFT findings (central, peripheral or normal) and to clarify the relationship between VFT results and the c...

BACKGROUND The medial vestibulospinal tract (MVST), which descends in the medial longitudinal fasciculus (MLF), may mediate the vestibular evoked myogenic potentials (VEMPs) in the contracting sternocleidomastoid muscle. We report herein abnormal VEMPs in a patient with medial medullary infarction (MMI) that appeared to involve the MLF. CASE REPORT A patient with infarction involving the righ...

Otolaryngologists typically perform diagnoses and offer medical treatment for vestibular dysfunction. This vestibular dysfunction manifests as benign paroxysmal positional vertigo (BPPV), Ménière's disease, vestibular neuronitis, and so on. The etiology of BPPV is still not clear, so in this article we discuss inner-ear function, etiology, and factors related to BPPV. We examined by pure-tone a...

Objectives. To investigate whether sensory function declines independently or in parallel with age within a single individual. Methods. Cross-sectional analysis of Baltimore Longitudinal Study of Aging (BLSA) participants who underwent vision (visual acuity threshold), proprioception (ankle joint proprioceptive threshold), vestibular function (cervical vestibular-evoked myogenic potential), hea...

objective to determine the changes in thyroid function tests in children who underwent antiepileptic therapy in shahid beheshti hospital, kashan, in 2008. materials & methods this analytical-observational study was carried out in a cohort fashion without an external control group (self controlled) on 45 children with new onset epilepsy who had not been previously treated with antiepileptic medi...

The patho-physiology of inner ear is an intriguing entity, which is yet to be understood in its full entirety. It is an interesting phenomenon to explore the way in which the labyrinth responds to various insults with a myriad of presentations manifesting clinically. Otologists have long wondered for a reasonable explanation as to why Stapedotomy patients may develop intense post-operative vert...

The diagnosis of patient disorders in modern neurootological centers has to include not only history and examination but objective and quantitative tests. In this study, we stress the importance of a short but significant test used to study vestibular function--the vestibular test of balance. The most common and widespread technique used to evaluate a patient's equilibrium in static condition i...
