Hello Karen,
Welcome to NeuroTalk
You could also ask over on the
Multiple Sclerosis Forum
As mentioned above, most of the posts regarding DBS will be on the
Parkinson's Disease Forum
You can find past posts by using the forum search feature (link below).
DBS will not work as a keyword though as it is only 3 letters long. The search term needs to be at least 4, so using Deep Brain Stimulation as the keyword will work better.

All the best to you with your decision.
