Advanced Seizure Control Through Vagus Nerve Stimulation
When medication alone does not provide full seizure control, advanced therapy options may help. One such option is Vagus Nerve Stimulation (VNS), a device-based treatment that sends mild electrical impulses to the brain through the vagus nerve.
At Georgia Epilepsy & Neurology Institute, Dr. Ki Hyeong Lee, MD and Dr. Joo Hee Seo, MD evaluate patients for VNS therapy and manage ongoing programming and follow-up for optimal outcomes.
What Is Vagus Nerve Stimulation?
VNS therapy involves a small device implanted under the skin of the chest with a thin wire connected to the vagus nerve in the neck. The device sends gentle, regular pulses to help prevent or reduce seizures.
Candidates for VNS
VNS may be recommended for patients who:
- Have not achieved full seizure control with medication
- Experience partial seizures or focal epilepsy
- Are not candidates for epilepsy surgery
- Desire additional non-drug therapy options
Evaluation and Follow-Up
Our evaluation includes reviewing medical history, EEG data, and imaging results to confirm eligibility. After implantation (performed by a neurosurgeon), follow-up visits with our team ensure proper device settings and progress tracking.
FAQs About Vagus Nerve Stimulation
Q: Is VNS surgery safe?
A: Yes. It is a minimally invasive outpatient procedure performed under general anesthesia by an experienced surgeon.
Q: How long does the device last?
A: Batteries typically last 5–10 years and can be replaced if needed.
Q: Can I feel the stimulation?
A: Some patients notice mild tingling or throat sensations that fade over time.
Q: How effective is VNS therapy?
A: Many patients experience significant seizure reduction and improved quality of life after consistent use.
Q: Will I still need medication with VNS?
A: Most patients continue taking medication, but often at lower doses or with better results.
