Summary
For Parkinson's disease (PD) patients with inadequate medical therapy, surgical interventions offer significant benefits. Procedures like thalamic stimulation and subthalamic nucleus (STN) stimulation can effectively manage refractory motor symptoms and improve quality of life.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Medical therapy for Parkinson's disease (PD) often becomes inadequate over time.
- Patients may experience increasing disability, motor fluctuations, dyskinesia, and tremor unresponsive to medication.
Purpose of the Study:
- To review the history and current state of surgical therapies for Parkinson's disease.
- To explore emerging neurosurgical options for medically refractory PD symptoms.
Main Methods:
- Review of historical and current surgical procedures for PD.
- Discussion of outcomes for thalamotomy, thalamic stimulation, pallidotomy, pallidal stimulation, and subthalamic nucleus (STN) stimulation.
- Overview of experimental cell transplantation therapies.
Main Results:
- Unilateral thalamotomy and thalamic stimulation are effective for contralateral tremor.
- Pallidotomy and pallidal stimulation primarily reduce contralateral dyskinesia.
- Subthalamic nucleus (STN) stimulation improves "off" period function and reduces "off" time and dyskinesia.
Conclusions:
- Surgical therapies offer significant benefits for select Parkinson's disease patients with medically refractory symptoms.
- Advances in neurosurgery provide a growing array of options for managing PD.
- Fetal cell transplantation remains an experimental area requiring further safety and efficacy studies.
