Grete My Dad, no PD but 85, when he had a hip replacement and a femoral artery( the main artery in the leg) by-pass within a couple of weeks. After both of these major surgeries it took him at least a week to recover a proper sense of emotional balance. In conversation with his anesthesiologist, I got quite a lecture on age- recovery rates. The substance was that it is quite common for "older" people to be quite disoriented for several days following major surgery. It would be interesting to me, a PD victim, to know whether there is a special susceptability to post-anesthesia-related disorientation amongst PDers. [log in to unmask]< Don Hoesterey>
