I know from my symptoms that I would be a poor candidate for DBS (rigid, dystonic , pd), plus I am too advanced now anyway. Yours is a personal decision to make, a very difficult one as you cannot predict the effectiveness of DBS, as it pertains to your particular pd manifestations. Some say it has made their life much better, others decline just as rapidly as they were going to anyway. It's a crap shoot at best. I wish you well, do not take this post as anything more than a simple comment.
