DBS for Epilepsy
Deep brain stimulation (DBS) for epilepsy is an implantable neuromodulation treatment that can reduce seizure frequency for selected patients whose seizures are not controlled by medication.
Epilepsy surgery pathway
From evaluation to long-term seizure care
Evaluation
Review history, imaging, EEG results, and medication response.
SEEG and mapping
Use video-EEG, imaging, and sEEG when needed to localize where seizures begin, how they spread, and what functions are nearby.
Decision
Choose resection, ablation, neuromodulation, further mapping, or non-surgical care.
Treatment
Carry out the selected procedure with a plan for safety, recovery, and seizure goals.
Follow-up
Track seizure control, medications, recovery, mood, and device settings when needed.
Precision mapping
MRI, video-EEG, neuropsychology, and sEEG when deeper localization is needed.
Tailored treatment
Resection, laser ablation, or neuromodulation selected around seizure anatomy and goals.
Long-term planning
Device programming, follow-up, and medication strategy coordinated with the epilepsy team.
Overview
Deep brain stimulation (DBS) for epilepsy is a neuromodulation option for selected patients with seizures that remain uncontrolled despite medication. Instead of removing brain tissue, DBS uses a surgically implanted system to deliver targeted stimulation to brain networks involved in seizures.
For epilepsy, DBS is generally used to reduce seizure frequency and severity over time. It is not intended to remove a seizure focus, and it is usually continued alongside medication and epilepsy follow-up.
Who it is for
DBS may be considered when seizures are drug-resistant and a seizure-removing operation is not appropriate, is too risky, or is unlikely to control the seizures. It can be especially relevant when seizures are difficult to localize or involve broader brain networks.
How the procedure works
DBS involves placing thin electrodes in carefully selected brain targets and connecting them to a small implanted pulse generator. After surgery, stimulation settings are adjusted over time to reduce seizure burden while minimizing side effects.
DBS is different from RNS. RNS records from one or two seizure-prone regions and responds to detected abnormal activity. DBS typically stimulates a deep brain network on a programmed schedule and is often considered when the seizure network is more distributed.
What to expect
After implantation, the device is activated and programmed. Seizure improvement may take time, and settings are adjusted over multiple visits. Seizure diaries, medication response, side effects, and device data all help guide long-term management.
Dr. Barone’s approach
Dr. Barone combines epilepsy surgery and functional neurosurgery training to evaluate whether DBS is the right neuromodulation option, or whether another approach such as resection, laser ablation, RNS, or VNS is better suited to the patient’s seizure pattern.
Frequently asked questions
What is DBS for epilepsy? +
DBS for epilepsy uses an implanted device to deliver controlled electrical stimulation to specific brain circuits involved in seizure activity. The goal is usually to reduce seizure frequency and severity over time, rather than remove the seizure focus.
Who may be a candidate for DBS? +
DBS may be considered for selected patients with drug-resistant epilepsy, especially when seizures arise from more than one area or when resective surgery is not the safest option. Candidacy depends on a comprehensive epilepsy evaluation.
Is DBS adjustable? +
Yes. DBS is programmed and adjusted over time after implantation. Settings are tailored to each patient's seizure pattern, response, and side effects.
