The process begins with a detailed evaluation completed weeks before surgery, including a specialized MRI, movement assessments, and medical clearance to confirm candidacy and guide surgical planning. During lead placement, electrodes are implanted in the brain at the hospital, typically followed within weeks by a separate outpatient procedure to place the neurostimulator under the skin of the chest. After activation, the device is carefully programmed over multiple follow-up visits to achieve the best balance between symptom relief and side effects, a process that often spans several months. Over the long term, DBS settings can be adjusted as symptoms or goals evolve, giving patients ongoing access to a care team experienced in long-term outcomes.
