Thanks for your posting. Yes I have both kinds of tremors (essential and Parkinsonian) I have difficulty writing and typing too, also I sometimes go blank when speaking and stop in the middle of a sentence.The most difficult problem is the restless legs syndrome where I have very bad cramps and shaking of both legs. I take a medicine called (Requip) which helps as long as I don't miss a dose. I do not know of any studies going on but would suggest contacting one of the bigger research hospitals. bye for now.
