In the 1980s and 1990s, a surgical DBS intervention was trialled for the treatment of PD.8 Deep brain stimulation (DBS) involves the implantation of one or more electrodes into specific regions of the brain.1,4 The electrodes deliver electrical stimuli to change or disrupt abnormal patterns of neural signalling.1 The process often results in improvements in motor function, as well as reduced motor complications.1 The treatment is now well established worldwide, and more than 200,000 patients have benefited from DBS.9
