i mean it worked in my dad. he was part of a trial to install DBS on moderate parkinson’s patients rather than waiting until the patients had severe parkinson’s. Short story, gave him ten extra years he could work. A bit longer and more details, he was able to manage nearly all of his dyskinesia through the implant rather than via medication (some kind of levi/carbidopa). It was a really neat device, the MDs who put it in were the best at what they do (and, as a professional patient I’ve gotten good at evaluating that) and provided us with all the support we needed up until dad died. So our experience was nothing but positive. I think the charger is in the garage and I can dig it up tomorrow to find out what company built his computer if you want.
