Vestibular schwannomas are benign neoplasms originating from the Schwann cells of the vestibular vestibular nerve of the vestibulocochlear nerve, and rarely from the pars cochlearis. These are tumors that are in contact with the nerve but do not bind the fibers. Benign neoplasms of the Schwann cells of the auditory and equilibrium nerves can also occur primarily in the inner ear and are referred to as intralabyrinthine schwannomas (ILS). Vestibular schwannomas represent 6-7 % of all intracranial and 90 % of cerebellopontine angle tumors...

Objectives: Direction-changing positional nystagmus (PN) was considered to indicate the presence of benign paroxysmal positional vertigo involving lateral semicircular canal in most cases. We investigated the incidence of PN on the supine head-roll test and compared the characteristics of nystagmus in patients with vestibular neuritis (VN) and Meniere disease (MD). Methods: A retrospective review of patients, who were diagnosed with unilateral VN or unilateral definite MD between September 2005 and November 2011, was conducted...

BACKGROUND: Deficits in sensory integration and fear of falling in complex environments contribute to decreased participation of adults with vestibular disorders. With recent advances in virtual reality technology, head-mounted displays are affordable and allow manipulation of the environment to test postural responses to visual changes. OBJECTIVES: To develop an assessment of static and dynamic balance with the Oculus Rift and (1) to assess test-retest reliability of each scene in adults with and without vestibular hypofunction; (2) to describe changes in directional path and sample entropy in response to changes in visuals and surface and compare between groups; and (3) to evaluate the relation between balance performance and self-reported disability and balance confidence...

Menière's disease is a disorder of the inner ear that causes vertigo, tinnitus, fullness, and hearing loss. Several pharmacological treatments are available, but none of them has shown significant results. Betahistine has been largely used but its effect on the main symptoms of Menière's disease remains unclear. In order to improve clinical appropriateness and to reduce the heterogeneity of the therapeutic approaches for Menière's disease, we proposed a European Consensus Conference on Betahistine's prescription...

Ménière's disease is a disorder of the inner ear that causes vertigo, tinnitus, fullness and hearing loss. Although several treatments are available, the success rate is reported to be around 70%, similar to placebo. Betahistine, a weak H1 receptor agonist and an effective H3 receptor antagonist, is frequently prescribed for Ménière's disease, especially to reduce recurrent vertigo attacks. The effects of this drug on hearing and other audiological symptoms remains unclear. Given the inconclusive reports in the literature, we proposed a consensus conference on the use of betahistine in Ménière's disease...

Background: Mental health comorbidities are frequent in patients with vertigo and dizziness. The current study was conducted in a specialized interdisciplinary university center for vertigo and dizziness. Clinical routines consist of a structured work-up in which neuro-otological and neurological tests are performed to first detect possible organic vestibular deficits. In addition, psychiatric disorders and comorbidities are considered. The study aimed to evaluate neurologists' awareness of psychiatric next to somatic disorders within patients' first examination in terms of diagnostic congruence between neurologists' diagnoses and structured clinical assessment of mental disorders...

Introduction: Mal de Debarquement Syndrome (MdDS) is a neurological disorder which affects the vestibular system pathways, manifesting as a constant sensation of movement in the form of rocking, bobbing, or swaying. The mechanism of MdDS is poorly understood and there is a lack of awareness amongst medical professionals about the condition. This study aimed to examine treatments and symptom management strategies used by MdDS patients and evaluate their self-reported effectiveness. Method: Motion-Triggered and Spontaneous/Other onset MdDS patients responded to a set of comprehensive questions as a retrospective survey regarding epidemiological details, diagnostic procedures, onset, and symptom triggers, hormonal influences as well as treatments and symptom management strategies used to reduce symptoms...

Gravity is a defining force that governs the evolution of mechanical forms, shapes and anchors our perception of the environment, and imposes fundamental constraints on our interactions with the world. Within the animal kingdom, humans are relatively unique in having evolved a vertical, bipedal posture. Although a vertical posture confers numerous benefits, it also renders us less stable than quadrupeds, increasing susceptibility to falls. The ability to accurately and precisely estimate our orientation relative to gravity is therefore of utmost importance...

Disorders of the inner-ear balance organs can be grouped by their manner of presentation into acute, episodic, or chronic vestibular syndromes. A sudden unilateral vestibular injury produces severe vertigo, nausea, and imbalance lasting days, known as the acute vestibular syndrome (AVS). A bedside head impulse and oculomotor examination helps separate vestibular neuritis, the more common and innocuous cause of AVS, from stroke. Benign positional vertigo, a common cause of episodic positional vertigo, occurs when otoconia overlying the otolith membrane falls into the semicircular canals, producing brief spells of spinning vertigo triggered by head movement...

The upright stance position is inherently unstable since the smallest deviation from a perfect upright orientation produces forces due to gravity that accelerate the body toward the ground. Stability is achieved by generating appropriate joint torques that correct for deviations from a desired orientation with orientation changes detected by sensory systems (primarily somatosensory/proprioceptive, visual, and vestibular systems). Functionally, balance control can be viewed as a closed-loop feedback control system with the integration of different sources of sensory orientation information being one component of the overall system, but with the system's feedback nature placing constraints on the sensory integration process...

To evaluate the role of video head impulse test in the diagnosis of peripheral vestibular disorders, we performed an observational study in the outpatient department in a tertiary setup in which the clinical head impulse test and the video head impulse test were performed on 45 patients with clinically suspected peripheral vestibular disorders, and their results were correlated. To analyse our results, each ear was counted individually and hence, among 45 patients, 12 out of 90 ears showed abnormal clinical head impulse test for lateral semicircular canals and 27 out of 90 ears showed abnormal video head impulse test for lateral semicircular canals...

Neurofibromatosis is a neurocutaneous, tumor predisposing, inheritable disorder characterized by tumors of the brain and spine and the presence of skin lesions. The most important tumors associated with neurofibromatosis are vestibular nerve schwannomas, with others being meningiomas and ependymomas. The cord is also affected by tumors, ependymoma being the commonest, besides meningiomas and schwannomas. We present a case with café au lait macules, neurofibromas in the skin, bilateral VIII cranial nerve schwannomas, multiple meningiomas in the brain and spine, ependymomas in the brain and spine, and schwannomas in the cauda equina nerve roots...

Background: Uncertainty continues to surround mild traumatic brain injury (mTBI) diagnosis, symptoms, prognosis, and outcome due in part to a lack of objective biomarkers of injury and recovery. As mTBI gains recognition as a serious public health epidemic, there is need to identify risk factors, diagnostic tools, and imaging biomarkers to help guide diagnosis and management. Methods: One hundred and eleven patients (15-50 years old) were enrolled acutely after mTBI and followed with up to four standardized serial assessments over 3 months...
