Optimizing Outcomes: A Review of Pre- and Post-Surgical Evaluations in Deep Brain Stimulation for Parkinson's Disease...

Deep brain stimulation (DBS) has significantly advanced the treatment of moderate to severe motor symptoms in conditions such as Parkinson's disease and essential tremor. Although DBS is generally considered a safe and effective therapy, selecting suitable candidates requires careful diagnostic evaluation and ensuring a stable neuropsychiatric baseline. Effective patient counseling is crucial, as it helps manage expectations regarding the potential benefits, the limitations of DBS, and the typical timeline for symptom improvement. This counseling is as important as the precision in surgical targeting to achieve optimal therapeutic outcomes. Once DBS is implanted, the remaining adjustable component is the programming of the device, which plays a vital role in patient response. Despite the absence of formal programming algorithms, various studies have provided collective insights into best practices, offering guidance on how to approach device programming for improved results. The aim of this review is to equip clinicians with valuable practical knowledge to enhance the management of patients undergoing DBS therapy, ultimately optimizing patient outcomes. By understanding the complexities of patient selection, surgical placement, and ongoing device management, clinicians can better tailor DBS interventions to individual needs and maximize the long-term benefits of the therapy.
