There was a post to the technical paper in Nature Medicine a few weeks ago about an innovation to traditional DBS. Adaptive DBS involves putting in brain sensors to automatically increase or reduce the amount of stimulation. Medscape had an optimistic review of the technology here:

TL;DR
"Adaptive DBS adjusts the intensity of stimulation based on the patient's need — increasing stimulation when PD symptoms break through and decreasing stimulation at other times to prevent potential side effects caused by stimulation"
"reduced the duration of motor symptoms by 50% compared with clinically optimized standard DBS"
"[programming] automation is crucial for making adaptive DBS more accessible"
"shows "great promise" but widespread implementation will likely take a few more years"
