We must consider how autonomic nervous system modifies or influences the results of the test in the vestibular function test. From this point of view, I have examined 48 (men and women) adults who subjectively and objectively have normal hearing abilities and equilibrious functions. First, I have classified them into two groups, one is the stable and the other is unstable groups of autonomic ne...

BACKGROUND Vestibular neuritis (VN) is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost. CASE PRESENTATIONS We describe three patients with symptoms suggestive of VN, but normal calorics. All 3 had...

background chronic vestibular dysfunction is a frustrating problem in the elderly and can have a tremendous impact on their life, but only a few studies are available. vestibular rehabilitation therapy (vrt) is an important therapeutic option for the neuro-otologist in treating patients with significant balance deficits. objectives the purpose of this study was to assess the effect of vestibula...

A dysfunction of the vestibular system is commonly characterized by a combination of phenomena involving perceptual, ocular motor, postural, and autonomic manifestations: vertigo/dizziness, nystagmus, ataxia, and nausea. These 4 manifestations correlate with different aspects of vestibular function and emanate from different sites within the central nervous system. The diagnosis of vestibular s...

OBJECTIVES Visuo-spatial neglect and vestibular disorders have common clinical findings and involve the same cortical areas. We questioned (1) whether visuo-spatial hemineglect is not only a disorder of spatial attention but may also reflect a disorder of higher cortical vestibular function and (2) whether a vestibular tone imbalance due to an acute peripheral dysfunction can also cause symptom...

Visual-vestibular and postural interactions can act as cues that trigger motion sickness and can also have a role in some anxiety disorders. We explore a method to detect individual sensitivity to visual-vestibular unusual patterns, which can signal a vulnerability to develop motion sickness and possibly anxiety disorders such as a fear of heights and panic. 65 undergraduate students were recru...

T he increased use of automobile transportation and lack of awareness of safety measures at work have resulted in many accidents, which have caused head and neck injuries. Direct blow to the head may result in minor brain injury, such as postconcussion syndrome. Flexion-extension or whiplash injury is a very common sequel of indirect trauma to the neck. Many patients suffering from these syndro...

The pathogenesis of motion sickness includes both inner-ear stimulation by body movement, especially a Coriolis-type stimulus, and optokinetic stimulation due to the shift of the surrounding visual fields. According to Kornhuber, Sakata and others, the vestibular cerebellum also participates in an important way. We conducted this study to elucidate the influence of the vestibular cerebellum on ...

This study investigated the frequency of vestibular disorders in developmentally disabled preschoolers who did and who did not have a history of otitis media. Fifteen children with a history of otitis media and fifteen children with no history of otitis media were given two tests for vestibular functioning: the Southern California Postrotary Nystagmus Test (SCPNT) and the Lateral Labyrinthine R...
