Calling it manic-depressive illness versus bipolar disorder

How many of you would prefer the term "manic-depressive," versus Bipolar? Personally, I prefer manic-depressive as I find the "Bipolar" term misleading and somewhat dehumanizing.

I mean, we have "Attention Deficit Hyperactivity Disorder," the description of the disorder is in the name.

Edit: Thanks for all the responses! It seems like there's a solid split of opinions on the matter. Maybe I'm just a bit nostalgic in my preferences.
