Hello, I am seeking information for my husband's father. He has had Parkinson's for 15 years and is still a young man (55). Recently a neurologist advised him to have the deep brain stimulation implant. His surgery date is fast approaching and he is looking for feedback from patients who have had this procedure. (Was it worth it? What improvements did you experience? What negative side effects did you experience? Do you still have to take your medication? Etc.) Thank you very much. Sincerely, Kari
