What actually is multiple sclerosis? can it cause deaf?

Immunologic disorder: Ms is an immunologic disorder most commonly occurring in young adults. It is more common in northern latitudes, less common towards the equator. The immune system attacks the insulating covering of nerves, reducing transmission speed and"short circuiting" the flow of information. Uncommonly it affects the auditory nerve producing hearing loss. I have never seen deafness as a result, it's possible.

Definition: Ms is an autoimmune disorder, associated with genetic and environmental influences. But we know that 99.5% of patients have had exposure to ebstein-barr virus, that vitamin d-3 deficiency may be a risk factor, that living north of latitude 42 increases incidence, and that cigarette smoking may be another risk factor. Deafness is rare, but unilateral loss of hearing can occur.
