My father, who is 72, was diagnosed with Parkinson's 14 years ago, and is having problems with hallucinations. I'm hoping that somebody on this list has had some success in dealing with this symptom. Dad is taking quite a lot of Sinemet: about 8 25/100 of the immediate release form (in hourly divided doses), and 2 50/200 of the CR type, each day. The hallucinations began (or at least became much worse) during a trial of Mirapex. Unfortunately, they did not remit much when the trial was ended. He is not taking any other dopamine agonists. His neurologist has had him try Seroquel (a new anti-psychotic drug) and Melleril (an old one), but neither drug helped, and they may have actually made the problems worse. He is barely functional on the current Sinemet dose, and does not want to reduce it unless it is absolutely necessary. Any suggestions? Robert S. Massey ***********************
