While vomiting is the extreme response, the predominant functioning of the vestibular system is to restore equilibrium as rapidly as possible. The vestibular nuclei are a major center for the integration of visual, vestibular, and muscular proprioceptive inputs and may also receive flight-related signals. Direct connectivity between subcortical nuclei (vestibular, collicular) and the oculomotor complex exists and these structures could interact independently of the cortex. The primary afferent projections of vestibular end organs are distributed to several ipsilateral vestibular nuclei. Some ototoxic drugs such as streptomycin and gentamicin are remarkably selective for the vestibular system, so that monitoring hearing is of little use. In addition, it highlights the role of alternative contemporary approaches in the management of vestibular schwannomas. Similarly, gravito-inertial structure (available to the vestibular system) taken alone is ambiguous with respect to this difference. The most common identifiable cause of bilateral vestibular loss is ototoxic drug exposure. Vestibular function can also be assessed at the bedside. Although vestibular input will eventually counteract the reflex, post-operative tilts in excess of 60 degrees were common. Some patients show improvement in vestibular function after ototoxic drugs are discontinued, but often the damage is irreversible. The sensation of orientation is made possible by cortical-subcortical mechanisms, including the vestibular system. Degenerative changes occur with age in the visual, vestibular, motor, sensory and cerebellar systems. Walking requires proprioceptive, visual and vestibular afferent information in addition to normal motor function. Patients with acute vestibular loss are unsteady and often veer or fall toward the side of the affected ear for several days after the event. However, as a secondary symptom to other vestibular cause of vertigo/dizziness, we find it more common. The asterisk shows the elevation known as the vestibular spine. The head rotation should however be lower than the trunk rotation since visual and vestibular head reflexes will operate to stabilize head in space. In addition, there are several ascending projections to the thalamus and vestibular cortex. However, for the majority of patients with identified peripheral vestibular dysfunction, the underlying pathological process may be poorly defined and specific treatment not available. Evaluating the dizzy patient: bedside examination and laboratory assessment of the vestibular system. Age-dependent changes in visual perception and proprioception have been demonstrated and degenerative changes in the vestibular receptor organs and vestibular nerve fibres have been reported. These are compound signals constructed from sensory afferents generated by various sensory systems (somatosensory, vestibular, and visual). To maintain postural stability when standing and walking, the brain must rapidly process signals from the visual, vestibular and somatosensory systems.
