Re: Unilateral vs. Bilateral VN
Hi! I think that bilateral VN is much more unusual...I think maybe one side is hit and then the other side is hit later???, but again very rare.
You will need to have inner ear testing: VNG test, including a caloric test, and possibly a rotary chair test, which I believe is more useful to determine bilateral damage. Best doc to see for this is a neurotologist.
