JGreentree Sounds like it's time to fire the "team" and move to another one. Hopefully they are not the only team in town and you can get a second opinion from another. Something is definitely not right with your DBS surgery. Has your team considered replacing the implanted pulse generator with a new unit. Since it was so effective when you first had the surgery and suddenly quit working correctly I would be very suspect of a malfunctioning generator. That unit is basically a battery, computer chip, and system board connecting the leads that are implanted in your brain. I've seen many a defective computer system board and chips in my day. They can and do fail sometimes doing crazy stuff before they die completely.
