ed,
something to consider about DBS is that with more and more acceptance of it and aging population, might be much longer waiting lists and higher out of pocket costs? so at the minimum, even if you want to put it off, at least get all the info you can especially where you would want to have it done.

DBS was always on the back burner, i thought the "cure" would be developed by now after 13 years since diagnosis. now i'm taking up to 200mg C/L every 2 hours, it's a long story but i woke up 1 morning a lot worse and i want a DBS, it's a no brainer. but it's obvious i waited too long. my point is, even if your're not mentally/physically ready for DBS, it never hurts to keep tabs on what's happening in R&D and who has the best record so if the need comes on suddenly, that you aren't in a panic to just "get in line" wherever you can and can attempt to get the best neurosurgeon/organization.
