Bruce-
What a great post! A lot of questions must arise daily about this topic. I wish I'd known an iota of what I do now when I applied and was accepted 5 years ago!
I read an article published by the APDA that also recommended to list other physical complications (related to PD or not.)
It seemed that my carpel tunnel was the deciding factor in my case. (and it was 6 months to the day for me! - I was 42) Also list if you have GERD, have broken bones because of falls, or any other problem(s) you may have consulted a doctor for that may be with you for life. The more problems, the better off you are

I had to fill out all these papers a second time after my DBS surgery for continuing SSDI. I was just a little peeved about having to do this again but was happy to oblige, plus add all the extras I'd not put on the first time. I was NOT so intimidated this time as the first time. Also, I was prepared to have, at my nurses advice, my stimulators turned off, sit in a wheelchair and be wheeled down to the SSDI office (in the same hospital as the Movement Disorders Clinic!) if I had to submit to a second doctor's opinion, like I did the first time. She told me they did that with a DBS patient and he had no problem "demonstrating" his PD. I also included in my second report that PD was degenerative and progressive, and that DBS surgery was not a cure but a last resort for a quality-life. Needless to say, I was approved again, but may have to go through this process again and again. It's the law.
Just my two-cents - I'm not from Missouri, but believe in "Give 'em hell, Harry".
