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.
The disturbances to vestibular function during periodic attacks are the primary distinction between vestibulocerebellar syndrome and other similar neurological syndromes. These conditions do not consistently cause the symptoms of dizziness and ocular impairment that have been localized to the vestibulocerebellum, leading researchers to ...
The term vestibular ataxia is used to indicate ataxia due to dysfunction of the vestibular system, which in acute and unilateral cases is associated with prominent vertigo, nausea, and vomiting. In slow-onset, chronic bilateral cases of vestibular dysfunction, these characteristic manifestations may be absent, and dysequilibrium may be the sole ...
Vestibulopathies are disorders of the inner ear. They may include bilateral vestibulopathy, [1] central vestibulopathy, [2] post traumatic vestibulopathy, [3] peripheral vestibulopathy, [4] recurrent vestibulopathy, [5] visual vestibulopathy, [6] and neurotoxic vestibulopathy, [7] among others. Tinnitus is a common vestibulopathy.
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
Vertigo is a relatively common symptom that can result from ischemia to the cerebellum, medulla or (rarely) the internal auditory artery which supplies the vestibular system of the inner ear. While vertigo is a common feature of VBI or posterior circulation stroke, VBI only rarely presents with vertigo alone (without other neurological signs). [5]
The most common disorders that result in vertigo are benign paroxysmal positional vertigo (BPPV), Ménière's disease, and vestibular neuritis. [1] [2] Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, migraines, trauma, and uneven pressures between the middle ears.
Vestibular neuritis is inflammation of the vestibular nerve (the nerve in the ear that sends messages related to motion and position to the brain). [ 2 ] [ 3 ] [ 4 ] Both conditions involve inflammation of the inner ear . [ 5 ]
