Cathy, No need to apologize for your questions. We all learn that way. The drug you refer to is pramipexole, a dopamine agonist, or helper drug, for sinemet. You're correct when you say your mother is not taking a lot of sinemet yet; it's still probably enough to cause dyskinesia, those involutary movements you notice. Most of us have a choice between that and rigidity - it's hard to find the ideal dose. It's all a juggling act. Pramipexole should be going on the market soon, so ask your mom's doctor about it. Good luck. Pat Schark pine`
