Deep Brain Stimulation
(DBS)
A highly advanced surgical procedure in which electrodes are implanted in specific areas of the brain to deliver electrical stimulation.
Duration
3-4 hours (electrodes); extra 1-2 hours (generator)
Hospital Stay
1-2 days
Effectiveness
60-80% symptom improvement in Parkinson's
Description
Deep Brain Stimulation (DBS) is a surgical procedure in which electrodes are implanted in specific areas of the brain to deliver electrical stimulation. This stimulation helps modulate abnormal brain activity and alleviate symptoms of various neurological disorders.
Indications
Procedure Steps
Stage 1: Stereotactic Frame Application
Local anesthesia is applied to scalp
Stereotactic frame is attached to skull
MRI or CT imaging is performed for precise targeting
Stage 2: Electrode Placement
Patient is positioned in operating room
Small burr holes are made in skull
Electrodes are carefully inserted into target brain areas
Intraoperative testing confirms correct placement
Electrodes are secured to skull
Stage 3: Pulse Generator Implantation
Small incision is made under collarbone
Pulse generator (similar to pacemaker) is implanted
Wires connecting electrodes to pulse generator are tunneled under skin
Incisions are closed
Recovery & Care
- • Gradual return to normal activities (2-4 weeks)
- • Avoid strenuous activity for 4-6 weeks
- • Avoid heavy lifting for 6 weeks
- • Pulse generator is activated 2-4 weeks after surgery
- • Regular follow-up appointments for programming adjustments
Programming
- ✓ Initial settings are conservative
- ✓ Gradual adjustments over weeks to months
- ✓ Patient feedback guides optimization
- ✓ Regular clinic visits for parameter adjustments
Effectiveness
60-80% of Parkinson's patients experience significant symptom improvement
• Benefits may increase over time
• Medication requirements often decrease
Potential Risks (rare)
- • Infection
- • Bleeding
- • Electrode displacement
- • Hardware malfunction
- • Personality or mood changes
- • Speech changes
Advantages
- ✓ Effective symptom control in many patients
- ✓ Adjustable (can be modified without surgery)
- ✓ Reversible (can be turned off or removed)
- ✓ Reduces need for medications
- ✓ Improves quality of life
Preparation
- • Detailed preoperative evaluation
- • MRI imaging for surgical planning
- • Neuropsychological testing
- • Informed consent discussion
- • Fasting before surgery
Cost Information
Significant; typically covered by insurance for approved indications.
