The most common vestibular diseases in humans are vestibular neuritis, a related condition called labyrinthitis, Ménière's disease, and BPPV. In addition, the vestibular system's function can be affected by tumours on the vestibulocochlear nerve , an infarct in the brain stem or in cortical regions related to the processing of vestibular ...
Other causes include Ménière's disease (12%), superior canal dehiscence syndrome, vestibular neuritis, and visual vertigo. [ 16 ] [ 17 ] Any cause of inflammation such as common cold , influenza , and bacterial infections may cause transient vertigo if it involves the inner ear, as may chemical insults (e.g., aminoglycosides ) [ 18 ] or ...
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke. [citation needed]
When the sense of balance is interrupted it causes dizziness, disorientation and nausea. Balance can be upset by Ménière's disease , superior canal dehiscence syndrome , an inner ear infection , by a bad common cold affecting the head or a number of other medical conditions including but not limited to vertigo .
BPPV is one of the most common vestibular disorders in people presenting with dizziness; a migraine is implicated in idiopathic cases. Proposed mechanisms linking the two are genetic factors and vascular damage to the labyrinth. [20] Although BPPV can occur at any age, it is most often seen in people older than the age of 60. [21]
Many inner ear disorders can cause dizziness, which leads to dysfunctional righting reflex action. Common inner ear disorders can cause vertigo in patients, which can be acute or chronic symptoms. [1] Labyrinthitis, or inflammation of the inner ear, can cause imbalances that must be overcome through therapeutic exercises.
Enlarged vestibular aqueducts can be bilateral or unilateral. Hearing loss caused by large vestibular aqueduct syndrome is not inevitable, although people with the syndrome are at a much higher risk of developing hearing loss than the general population. Hearing loss is very likely.
Symptoms can include: [citation needed] A constant sense of unsteadiness, rocking or swaying, dizziness or lightheadedness; Disequilibrium on most days for at least 3 months; Spatial orientation problems; Off-kilter sensation; Extreme sensitivity to movement and/or complex visual stimuli such as grocery stores or driving in certain weather ...
