Ah, sometimes I think most of them (neurologists) are just kind of "funny".
I've seen many, many specialist. I've been to at least one doc every specialism.
And well, not to generalize of course, but they just always seem to be a bit strange in their contact wit patients, kind of like they lack some kind of social skills.
This is just my experience, but my reumatologists never say: "oh you look all bloated" and make a sound to indicate my moonface "PFFFRRRT" when I show myself after starting prednisone. My haematologist or endocrinologist accept that I'm not just a random patient who lies there and waits for god-in-white-coat-almighty to do something, but that I want to be involved. Two neurologists talking about me, and use stuff like "globulines" and "melanoma" smile and say "Just look the other way, we're talking difficult stuff here. It's jibberish for you".

Not to generalize, there must be some non autistic out there.

Good luck with an enocrinologist! I know the best, he is fantastic, my best doc ever. He's not in the US though, sorry.
