Thanks to everyone who responded to my request regarding pallidotomy. My mother had her operation July end at the Hospital for Joint Diseases in NYU NY. She is currently 55 years old and has had PD for 11 years . she had a lot of stiffness, slowness of movement, on/off and dyskenesia but virtually no tremors. She was estimated to be 30% worse on the right side than the left and went in for a left Pallidotomy with Dr. Kelly. Dr. Fazzini was our neurosurgeon who evaluated her for the procedure. It is now 2 weeks since the operation and she has had dramatic improvement so far. While she could not walk more than 10 feet except with great difficulty and with assistance even while on medication prior to the procedure, she could get up easily and walk with no assistance and could turn by herself after the operation. We wandered around malls together 4 days after the operation, something that would have been impossible before. She has no dyskenesia on the right side 50% improvement in stiffness/slowness of movement on the right side (and 25% on the left) and no sweating. The most dramatic improvement is in her on/off state. While before she could not even get up in her off state, now she was wandering in the mall in what would have been her off state (It was like a miracle!). She still has dyskenesia on her left side (but we were told that that would be the case). A word on the hospital and all the attending doctors. They were all completely wonderful and made the whole experience easy for us. The staff at the hospital (particularly the nurses) were just incredibly nice and attentive. Both Dr. Kelly and Dr. Fazzini were wonderful and extremely genorous with their time to answer questions. The recovery time is really quick, my mother left the hospital in two days and has left for India a week after the operation. If anyone has any questions I would be happy to help in any way I can. Cheers Ram
