Central vestibular disorder is common after middle cerebral artery (MCA) territory infarction. The MCA supplies blood to the parieto-insular vestibular cortex (PIVC), a core region of central vestibular symptoms. We report on patients that sustained injuries of the core vestibular pathway to the PIVC with central vestibular disorder following MCA territory infarction, demonstrated on diffusion ...

INTRODUCTION Disorders of the auditory and vestibular system are often associated with human immunodeficiency virus infection and acquired immunodeficiency syndrome. However, the extent and nature of these vestibular manifestations are unclear. OBJECTIVE To systematically review the current peer-reviewed literature on vestibular manifestations and pathology related to human immunodeficiency v...

PURPOSE To characterize the recording and analyze the results of the combined cervical and ocular vestibular evoked myogenic potential in individuals without hearing and vestibular complaints. METHODS In this study, 30 individuals without hearing complaints and hearing within normal limits were evaluated. Data were collected through the simultaneous recording of cervical and ocular vestibular...

It is now well established that vestibular information plays an important role in spatial memory processes. Although vestibular lesions induce anxiety in humans, this finding remains controversial in rodents. However, it is possible that anxiety-related behavior is associated with spatial memory impairments after vestibular lesions. We aimed to evaluate anxiety-like behavior and the effect of a...

The vestibular system is important for the development of normal movement reactions, motion tolerance, and motor control for postural alignment, balance, and vision. A vestibular system that is damaged by disease or injury in childhood can have a major impact on a child's development. In addition, the emergence of vestibular lesions may also lead to cognitive deficits, including attention defic...

introduction: the aim of this case report was to investigate the relationship between sleep disorders and audio vestibular symptoms.   case report: a case of undiagnosed sleep disorder, presenting as a temporary auditory processing difficulty, is presented. the disorder was initially treated as sudden deafness with dizziness. a 23-year-old male patient complained of acute hearing disturbance de...

Sixty patients were selected for cochlear implantation and 50 of them received an intracochlear implant (Nucleus). Vestibular function was evaluated before and after surgery using a caloric test and a velocity step test. Sixteen patients had normal or residual vestibular function before surgery, 11 bilateral and 5 unilateral; in 3 of the latter patients, the ear with vestibular areflexia was el...

Balance requires the integration of proprioceptive, visual, and vestibular sensory inputs. Contributions from the vestibular system are increasingly important when other sensory signals are lacking or erroneous [1]. Galvanic vestibular stimulation (GVS), the application of a small electrical current across the mastoid processes, has been used to apply a stimulus to the vestibular system indepen...

The vestibular system contributes to the generation of conjugate eye movements, spatial orientation, and postural control. The functional connections of the vestibular end-organs and of the descending vestibulospinal pathways and their importance to postural control were reviewed in the previous paper by Keshner and Cohen (pp. 320-330). This paper reviews the ascending vestibular pathways, the ...

This work compared the effect of unilateral (right and left) and bilateral vestibular stimulation in a right-brain-damaged patient with neglect. Neglect was improved following left caloric vestibular stimulation, and worsened following right vestibular stimulation. On the other hand, no modification of neglect was observed after bilateral vestibular stimulation. These results support the idea t...
