I have a question - Since DBS has not yet received FDA approval, and I assume is still considered experimental in the US, how difficult is it to be accepted for the surgery? How do you find a qualified surgeon? Do you have to be enrolled in a study? Does Medicare, Medicaid or any private insurance presently cover the costs of the surgery, the device and the follow up adjustments? Ok - that was actually more than 1 question, but would appreciate answers to any or all of them. Thanks, Linda
