HYPOTHESIS That disease or dysfunction of vestibular end organs in human patients will reduce or eliminate the contribution of the affected end organs to the total eye-movement response to DC surface galvanic vestibular stimulation (GVS). BACKGROUND It was assumed that DC GVS (at current of 5 mA) stimulates all vestibular end organs, an assumption that is strongly supported by physiological e...

Vestibular symptoms are persistent and problematic sequelae of blast exposure. Several lines of evidence suggest that these symptoms often stem from injury to the central nervous system. Current methods of assessing the vestibular system have described vestibular deficits that follow traumatic brain injury and differentiate blunt and blast trauma but have not examined the full range of vestibul...

OBJECTIVE To report the nationwide prevalence of dizziness and vestibular dysfunction in the Korean population and determine the associated factors. DESIGN Cross-sectional analysis of a nationwide health survey. METHODS We obtained data from the 2009 to 2010 Korea National Health and Nutrition Examination Surveys, which were cross-sectional surveys of the South Korean civilian, non-institut...

Despite the importance of symptomatology in the diagnosis of vestibular dysfunction, the qualitative nature of the symptoms related to semicircular canal (canal) versus otolith dysfunction is not fully understood. The purpose of this study was to compare symptoms, and their severity, in individuals with canal versus otolith peripheral vestibular dysfunction. A subjective tool, the Descriptive S...

OBJECTIVES/HYPOTHESIS To identify clinical characteristics of pediatric superior semicircular canal dehiscence (SSCD) and explore suitable options of management. STUDY DESIGN Retrospective review. METHODS The study comprised 10 patients with auditory and/or vestibular symptoms suspicious for SSCD. One patient pursued care at another institution, and two did not return for follow-up. Subsequ...

BACKGROUND Case reports are presented on four Veterans, aged 29-46 years, who complained of chronic dizziness and/or postural instability following blast exposures. Two of the four individuals were diagnosed with mild traumatic brain injury and three of the four were exposed to multiple blasts. Comprehensive vestibular, balance, gait, audiometry and neuroimaging procedures were used to characte...

Purpose: To assess body balance and to quantify possible alterations over the static posturography of the Balance Rehabilitation Unit (BRU) in patients with vestibular dysfunction. Methods: Retrospective study, with files of 100 patients with topographic diagnosis of peripheral or central vestibular dysfunction and 100 healthy individuals that composed the Control Group, of both genders, with a...

Introduction: Vestibular abnormalities are common problems in the whole world, which can lead to bilateral vestibular dysfunction (BVD). That results in symptoms, such as vertigo, unsteadiness, falling, oscillopsia, and lower quality of life. The Objective of this study was to determine BVD in adults and elderlies with vertigo and unsteadiness.   Materials and Methods: This study was conducted ...

Vertigo is caused by unilateral vestibular dysfunction. Unilateral vestibular dysfunction represents either vestibular overactivity as benign positional vertigo or underactivity as in labyrinthitis or both, at different times, as in a Ménière’s attack. Unilateral dysfunction could also be central rather than peripheral, such as in a lateral medullary syndrome. Unilateral vestibular dysfunction ...

Dizziness is a common symptom in medical practice, and may be associated with over 300 diseases. Although most cases of dizziness are related to vestibular system dysfunction, some result from involvement of other parts of the body. Recent studies have shows that there is an association between auditory/vestibular symptoms and autonomous nervous system dysfunction, suggesting that this may be a...
