Multiple Sclerosis

What is Multiple Sclerosis (MS): How is it Related to Dizziness and Imbalance?


Multiple Sclerosis (MS) is a degenerative autoimmune disease process that results in the episodic demyelination of neurons, or nerves. Many of the body’s neurons are partially coated in a fatty substance called myelin that protects the nerve and also speeds up its transmission of signals. MS can affect any part of the body and can be localized or widespread. If demyelination occurs within the temporal lobe, cerebellum and/or brainstem, patient is likely to experience dizziness and imbalance.


Multiple Sclerosis Vestibular Testing:

Indications of central lesion may be revealed during videonystagmography (VNG) testing. VNG central indications may include: abnormalities of eye movements, direction-changing nystagmus within one head position, or nystagmus exacerbated by visual fixation. Upon caloric testing, a gain asymmetry can be noted indicating presence of demyelinating pathology. This information can then be sent to patient’s referring physician for further investigation.


Multiple Sclerosis Vestibular Management:

Dizziness, imbalance and fall prevention can be addressed via vestibular rehabilitation and balance retraining therapy as prescribed by a physical therapist. Refer to this link for more information regarding vestibular rehabilitation and balance retraining therapy:
