Deep Brain Stimulation

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Indications

Primary Indications

Parkinson's disease with motor fluctuations or dyskinesiasMedication-refractory essential tremorGeneralized or segmental dystoniaSevere OCD unresponsive to pharmacotherapy and psychotherapy

Mechanism

DBS delivers continuous electrical stimulation to targeted brain nuclei (e.g., subthalamic nucleus, globus pallidus internus, ventral capsule/ventral striatum), modulating pathological neural activity and restoring more normal circuit function.

Protocol

Preparation

Multidisciplinary evaluation; neuroimaging (MRI/CT) for targeting; neuropsychological testing; informed consent.

Procedure

Stereotactic implantation of intracranial electrodes under local or general anesthesia.
Connection of electrodes to an implantable pulse generator placed subcutaneously in the chest wall.
Postoperative programming of stimulation parameters over multiple visits.

Frequency: Continuous stimulation; follow-up visits every few months for optimization.

Duration: Years; device battery replacement or recharging required periodically.

Total Treatment Time: Initial surgery plus lifelong follow-up.

Equipment

Session Structure

Pre-Session

Preoperative evaluation and planning.

Treatment Phase

Surgical implantation followed by stimulation initiation.

Post-Session

Device programming and maintenance visits.

Expected Outcomes

Immediate

Partial symptom relief upon stimulation initiation

Short Term

Improved motor function
Reduced tremor or dystonia
Decreased OCD symptom severity

Long Term

Sustained symptom control
Improved quality of life

Side Effects

Poor compliance with follow-up
High surgical risk

special considerations

Careful psychiatric screening to minimize adverse mood effects.

Greenberg BD, et al. Deep brain stimulation of the ventral internal capsule/ventral striatum for OCD: worldwide experience. Mol Psychiatry. 2010;15(1):64–79.

Limitations

Requires surgery; potential for hardware complications; not effective for all patients.

Cost Considerations

typical session cost: Surgical procedure $35,000–$50,000; follow-up programming visits $200–$500

total treatment cost: $50,000–$100,000 including device and follow-up over initial years

insurance coverage: Common for FDA-approved indications; variable for psychiatric applications

cost effectiveness: High for severe, medication-refractory movement disorders

Integration Support

Concurrent Therapies

Medication adjustments
Physical therapy
Psychotherapy for psychiatric indications

Special Populations

👶Pregnancy

Device can remain in place; avoid surgery during pregnancy unless urgent.

Clinical Notes

DBS is adjustable and reversible, offering advantages over ablative procedures.
Requires lifelong follow-up and device management.
Emerging psychiatric applications require further study.
