Are you asking why they don't do this when you are first diagnosed? I'm 59 and diagnosed at 36. I have been putting it off for at least ten years until it just became unbearable to be me. My doctors wanted me to do it but I wouldn't do it basically because it used to have a higher rate of failure. Now that I got it I am not sorry I waited. I had to be sure in my mind. If I could take a few pills and be fine for eleven years I would be happy with that also. I was at the point where I had no life but strangely like you if I couldn't walk an inch but you put me next to a staircase I could run up and down it all day long. I also walked backwards a lot with my walker. I have been on sinemet in one form or another since the beginning. Do they want to do DBS on you now?
