Enlarged vestibular aqueduct (EVA) is one of the commonly identified congenital temporal bone abnormalities associated with sensorineural hearing loss. Hearing loss may be unilateral or bilateral, and typically presents at birth or in early childhood. Vestibular symptoms have been reported in up to 50% of affected individuals, and may be delayed in onset until adulthood. The details of nystagmu...

Patients with acquired chronic bilateral vestibular loss were recently found to have a significant impairment in spatial memory and navigation when tested with a virtual Morris water task. These deficits were associated with selective and bilateral atrophy of the hippocampus, which suggests that spatial memory and navigation also rely on vestibular input. In the present study 16 patients with u...

To understand the neurochemical mechanisms underlying the vestibular compensation, we determined the levels of amino acids such as aspartate, glutamate, glutamine, glycine, taurine, alanine in the medial vestibular nucleus (MVN) following unilateral labyrinthectomy (UL), by using in vivo brain microdialysis and high-performance liquid chromatography technique. Rats were pretreated by infusing 2...

OBJECTIVE To evaluate the short-term effects of vestibular rehabilitation on symptom, disability, balance, and postural stability in patients with chronic unilateral vestibular dysfunction. DESIGN Randomized controlled trial. SETTING Department of Physical Medicine and Rehabilitation, University Hospital. PARTICIPANTS Patients (N=42) with chronic vestibular dysfunction were divided into e...

BACKGROUND A few studies in humans suggest that changes in stimulation of the balance organs of the inner ear (the 'vestibular system') can disrupt numerical cognition, resulting in 'dyscalculia', the inability to manipulate numbers. Many studies have also demonstrated that patients with vestibular dysfunction exhibit deficits in spatial memory. OBJECTIVES It is suggested that there may be a ...

both the peripheral vestibular system, that is, the labyrinth, and the central vestibular system, is known to influence autonomic function in several ways that have clinical implications. This paper discusses evidence for vestibular influences on autonomic control from normal human subjects, evidence for vestibular influences on autonomic control from patients, clinical implications of vestibul...

The aim of our study was to establish a new diagnostic approach, through the use of virtual reality, to the study of the subjective vertical bar in unilateral peripheral vestibular dysfunction. We subjected 174 patients with unilateral peripheral vestibular dysfunction (ages 18-82 years) to vestibular diagnosis with the virtual reality system. We changed the classic configuration of the subject...

Topicality: Despite the fact that during cochlear implantation can have negative impact on peripheral part of vestibular analyzer, in most clinics perform CI, there is no routine examination function pre- and postoperative periods. Aim: to study condition analyzer children with sensorineural deafness before after through analysis quantitative characteristics rotational test. Material methods: T...

The vestibular system contributes to a wide range of functions, from postural and oculomotor reflexes to spatial representation and cognition. Vestibular signals are important to maintain an internal, updated representation of the body position and movement in space. However, it is not clear to what extent they are also necessary to mentally simulate movement in situations that do not involve d...
