I'm 46 and was diagnosed 18 months ago... and got the same impression as Kate that you're taking a lot of meds. Actually, it's not so much the quantity of meds (I'm also taking a fair number, if I count the number of pills/day). The thing that I found striking is that your meds seem to be the l-dopa meds which everybody apparently will have to go through sooner or later... but which I'm not taking yet and which I'm personally trying to postpone. Of course, PD seems to vary a lot from person to person and the two neurologists I see tell me there is no real drawback to taking l-dopa. Despite their reassurance, I confess I do have a prejudice against l-dopa because (a) of it's side effects and (b) it seems to work less well after a few years. I guess I'll have to go through it too, but my personaly philosophy for the time being is: the later the better.
I'm conscious there's a fair chance I may have gotten everyting wrong. And so, I'm not going to suggest that anyone does what I do (note I have no medical background) but anyway, for whatever it's worth, here's a short summary of what I'am doing, which is obviously what I believe is best for me:
1. Do exercise (I've started taking 2 hours / week of swimming classes)
2. Eat better (I've seen a nutricionist and added a few twists of my own)
3. Seek to avoid stress (easier said than done for me - not doing so well on this one)
4. Went back to my old medical check-ups (plus did new ones) and now am seeking to fix anything that looked out-of-norm (even if the doctors tell you it's not important - in my case I find it especially suspicions that I have low vit D and some signs of inflammation; all doctors tell me it's not a big deal, but I can't avoid thinking there might be a link with PD)
5. Take some neuroprotective stuff or stuff that is thought to help with PD (I take CoQ10, Vit E, Vit C, and magnesium.
6. Take Azilect (rasagiline; prescribed by one of the neurologists i see; the other one says she doesn't perscribe it as she doesn't believe it makes any difference)
7. Take l-tyrosine -> note this one is potentially dangerous, so DO NOT take it lightly in combination with rasagiline/selegiline or any MAO-inhibitor (see http://www.parkinsons.org.uk/pdsforum/posts.aspx?forum=treatments&topic=l-tyrosine-supplements
Again, the above is just what I'm trying to do for myself in case it might give you any ideas. I have no idea if it will have any positive/negative long-term effects nor if it works better/worse for anyone else. I can only say that so far my PD symptoms are light and haven't progressed much (if at all) in the past 18 months... If you (or any one else) is interesting in any of the above topics, just let me know and I'll be happy to go into much more detail in any of the topics above. I am also obviously interested in any comments/insights/experiences anyone might have about any of them too.
Hope this helps and good luck,
