Patricia: I had my right side pallidotomy a year ago this month, on 2 April 96. Mine was performed at the U of Utah Research Hospital. It was adjudged as successful by both myself and the Neuro-Surgeon. My primary complaints were: Freezing; ON-OFF(mainly off) ;left side immobility or bad diskinesia. My tolerance to Sinemet was a very narrow window, I seemed to be either underdosed or overdosed. Immediately after the operation, I had total elimination of my left side symptoms. My meds were immediately reduced to approximately one-half. I continued to have minor improvement in mobility and mental attitude for approx six months. After this time, the progression of the Parkinson's started to show up on my right side, and continues to increase. I now take 5 Sinamet (25/100) per day and 2 Eldepryl per day,which is about 2/3 of what I was taking prior to the Pallidotomy. Other than that I take some E and C vitamens. I no longer drive or have much stamina. You should have been briefed that the Pallidotomy would neither cure the disease nor affect the other (right) side. You need the meds to help fight this disease. Don't fell bad or depressed that you still need them. Enjoy the improved quality of life you can expect to have now, and rejoice. If we can be of any help, just let us ( The Parky List) know. Ron C. 63/9
