Has anyone on this board heard of bilateral vestibular dysfuction with polyneuropathy?

I did a random internet search last night and came up with a few hits on the bvd + pn but there wasn't too much info. In may 2007 after my vertigo hit I had a VNG/ENG done that showed I had severely reduced responses to the caloric testing. None of my doctors have even commented on that or suggested we investigate further.

Anyone with a similar experience.
