In all my conversations with my neuro and research online I have found that the only thing we know with absolute certainty is that exercise delays the progression of PD.
The Stalevo, and to a lesser extent Azilect, have to this point successfully managed my symptoms so well that I have returned to running. I have worked my way back to 2 miles a day with my sights set on a 5K next month and a 10K after that. The result has been the conquering of my lingering depression, better leg strength, increased stamina, better and longer sleep cycles, and more.
My point is this. I was diagnosed in June of this year at the age of 45. In short order I slipped into a depression that robbed me of the joy there is in life. I withdrew from my family and became angry and resentful. Running has given me back my life. I urge those of you newly diagnosed and those that may have given in to the darkness to stay active and stay plugged in. Get active in these forums, join a support group, and get active with a exercise routine that includes stretching. You will be amazed at how much better you feel physically....and mentally. I for one refuse to be defined by my illness.
Happy Thanksgiving.
