Typical risks - there's a 1-2% prevalence of hemorrhage which usually isn't too bad. It's really rare to have a major event. The other major risk is infection (as with all implanted hardware), or device malfunction. Otherwise, the most common side effects that could happen is that the stimulation causes some spasms or tingling. There's some hand-waving as to whether it may increase susceptibility to depression or falls, but that is hard to tease out between disease progression. Of note, if it's Parkinson's, one hard part is that the meds will have to be adjusted a lot post-op which cause some folks problems.
