Joao, Yes have briefly considered DBS: but chickened out on the day of surgical consult. You see for the first eight years of having pd I had to rely on my emotional strength for a I was misdiagnosed as psychosymatically causing my symptoms. I have a fear that something would go wrong and I would lose my mental capabilities. There is always a risk. I would be interested in knowing the reason you are asking? Thanks so much for the question> Sandy Norris 40/28/20 "Faith is the daring of the soul to go farther than it can see."
