Is Meniere's Disease really a disease?

Meniere's Disease is a idiopathic condition - translation nobody know the cause of it. There are plenty of opinions of why it happens to certain people. It could be an injury, or a virus in the inner ear or something that no one has ever thought about. I know in my own case that it came about when I had a car accident. One of the first ENTs that I saw balked at that idea because the wreck that I was in wasn't that bad. But I find it strange that I started to have attacks right after the car wreck.
Now I have also had a history of ear problems since I was young I don't know if that is the reason that I am stuck with this MD stuff.

I haven't been feeling bad lately so ( knock on wood ) maybe I'm getting better. Maybe.
