Deep brain stimulation (DBS) is an advanced surgical treatment for Parkinson's disease that uses implanted electrodes to modulate abnormal neural activity in specific brain regions. It is an established therapy for patients with motor complications not adequately controlled with medication[1][2].
DBS delivers electrical impulses to targeted brain structures:

Considerations:
| Symptom | Improvement with DBS |
|---|---|
| Tremor | 60-80% |
| Rigidity | 50-70% |
| Bradykinesia | 50-70% |
| OFF-medication time | Reduced by 4-6 hours/day |
| ON-time with dyskinesia | Reduced by 50-70% |
| Factor | DBS | Levodopa-Carbidopa Intestinal Gel | Apomorphine |
|---|---|---|---|
| Invasiveness | High | Moderate | Low |
| Reversibility | Yes | Yes | Yes |
| Target | Neural circuits | Dopamine replacement | Dopamine receptor |
| Medication change | Can reduce | Can reduce | Continuous + rescue |
| Cognitive impact | Possible | Minimal | Minimal |
| Best for | Motor fluctuations + tremor | Motor fluctuations | Motor fluctuations |
