I am curious to find out now how Walt made out having just realized that this all happened five years ago now. What was the implantation of the control unit like? How long did it take to alleviated his symptoms? DID IT alleviate his symptoms? What would he say about the procedure now five years out? I am honestly hoping for a happy ending to Walt's journey, wonderfully chronicled by his loving, and articulate wife. Thanks for sharing, some of us are still considering DBS and it really helps.
