Jen, I think Jane described young onset PD pretty well. In your father's case, being less than 55 years old, he would probably still fit that definition. Indeed, it usually progresses at a slower rate the younger you are. When I was first told I had PD, and had read an article that said something about having 15 good years once diagnosed, I tearfully went to my movement disorders specialist/ neurologist expecting to hear I had better get my affairs in order. Instead, he reassured me, that while I would have PD all my life, which was going to be as long as it would be without PD; it wouldn't kill me because we have medicines than keep you going whereas that wasn't the case 40 years ago. He said that would be my biggest challenge; being on medicine the rest of my life. Well, I "rocked and rolled" for quite a few years before I was correctly diagnosed; went on Sinemet which did me well for 6-7 years, and then tried every agonist; most of which I couldn't tolerate. I went the route of retiring after 21 years of teaching, getting disability (SSDI), and in May of 1999, had experimental bilateral brain surgery (DBS/STN), which has given me a new lease on life. With all of that going on, oh yes, I also have gone through menopause. I now have little computers in my chest, sending out electrical pulses through wires that run under my skin and up into my brain; a bionic woman!! A walking miracle!! It has all been an adventure, I think, and I feel I wouldn't have experienced as much of what life held in store for me. Parkinson's MADE me slow down and smell the roses!! Your dad's outlook on life in general will have a lot to do with how he adjusts to this new twist in his road. I can't speak for a man, but as a Parkie, I know that support, encouragement, etc. is ultra-essential from my loved ones! He'll need it from you, so don't be afraid to support him, love him, and help him learn all there is about what is happening. I, for one, rejoiced when I was finally diagnosed, because no doctor had gotten it right for years. My first symptoms were evident to other people when I was 30 and my son had just been baptized. It took several years, and even after diagnosis, I had doctor/friends who were in disbelief; I was just too young!! We have learned so much about this disease/condition in the past 5 years, it's almost hard to remember such attitudes existed. Michael J. Fox has shed light on the fact that this isn't just for "old folks." My best wishes to your father and your family, as you all move ahead to find out what is going on. Knowing will be better than not knowing, in my opinion. Good luck, and keep reading. You are being proactive and that will be a blessing!
