Thanks so much for the answer. I am already on meds for essential tremor (propanolol) but I wasn't sure if the head movement thing was essential tremor or not. No one in my fathers family have this head thing (except my Dad).
Thanks again.
Yes, she did have essential tremor. It is not the same as Parkinson's and some believe it is indeed genetic. Hepburn's grandfather had it. Here is a link to some of the more recent ideas about the disorder:

There are other websites, if you'll Google for it, that have other info on it, trials to see what helps it, and so on. As far as I could tell from a variety of websites I looked at concerning this health issue, no one has come up with a solution to help or prevent it, so I'm not sure if the RLS meds you asked about will have any effect on it one way or the other.
I think you should take your interest in it and do some research on the subject, get involved, because many more people suffer from tremor than even Parkinson's!
Doesn't anybody know what was wrong with her?
