I am knew and this is my first post. I have Parkinson's Diesease. I have had Deep Brain Stimulation surgery. I have 3 leads in my brain. I have been back to Mayo quite a few times. They are having trouble controling my leg tremor. They have mentioned a 4th. lead might be necessary to control the tremor. Is there anyone out there that has had the surgery and how many leads do you have ? It has been working but not for my tremor. At least not without giving me speech problems. My biggest symptom was leg tremor and still is. If there is any thing someone thinks I should know before having the next surgery please let me know.
