As a candidate for DBS of the Globus Pallidus, I have discussed DBS of the STN with a member of the team at ANRI (the Australian Neuromuscular Research Institute). The advice I have been given is that as a double DBS of the STN is preferred to a single DBS/STN those of us who have had a pallidotomy are not considered as candidates - at this time - for DBS/STN. Anyone contemplating surgery should keep this caveat in mind. Dennis +++++++++++++++++++++++++++ Dennis Greene 49/dx 37/ onset 32 There's nothing wrong with me that a cure for PD won't fix!
