ROCHESTER, Minn. – November 21, 2025 – In a significant leap forward for neurology, researchers at the Mayo Clinic have developed a personalized approach to Deep Brain Stimulation (DBS) that targets the unique neural architecture of individual patients. By mapping specific brain wave patterns to identify precise “hubs” in the thalamus, this new method moves beyond merely controlling seizures to potentially rewiring the brain to “forget” them entirely, offering new hope for millions with drug-resistant epilepsy.
Key Takeaways
- Personalized Precision: The new protocol uses individual brain mapping to target the specific thalamic area connecting to a patient’s seizure network, replacing the traditional “one-size-fits-all” placement.
- Potential for Cure: Unlike standard DBS, which acts as a pacemaker to manage symptoms, this approach aims to reorganize neural networks to permanently reduce excitability.
- Study Success: The method was successfully evaluated in 10 patients and detailed in a new study published in the Annals of Neurology.
- Strategic Innovation: This breakthrough is part of Mayo Clinic’s BIONIC initiative, which merges clinical expertise with advanced bioelectronic engineering.

Precision Over Protocol: The New Approach
For decades, Deep Brain Stimulation (DBS) has been a lifeline for patients whose epilepsy does not respond to medication. Traditionally, this procedure involves implanting electrodes in a standardized location within the thalamus—a “one-size-fits-all” strategy that, while often effective, fails to account for the unique neural wiring of each patient.
The new Mayo Clinic protocol upends this standard. Led by neurologist Dr. Nick Gregg, the research team realized that to achieve better outcomes, they needed to target the specific network responsible for the seizures, not just a general anatomical region.
“We’re moving away from one-size-fits-all to an individualized approach that maximizes seizure network engagement to better modulate abnormal brain wave activity.” — Dr. Nick Gregg, M.D., Mayo Clinic Neurologist.
Mapping the “Seizure Hub”
The innovation relies on advanced diagnostics. Because seizures are often infrequent, researchers analyze erratic brain wave patterns during non-seizure periods. These patterns act as breadcrumbs, leading physicians to a specific “hub” in the thalamus that serves as the central connector for that patient’s unique seizure network.
By fine-tuning stimulation to this exact location, the device can disrupt “pathological hypersynchrony”—the abnormal, synchronized firing of neurons that triggers a seizure—with far greater efficiency than standard placement.
From Management to Cure
The most provocative aspect of this research is its long-term ambition. Standard DBS is typically viewed as a management tool—effective only as long as the device is on. The Mayo team, however, posits that their personalized approach could lead to lasting physiological changes.
Dr. Gregg explains that by persistently quieting the specific seizure network, the brain may eventually reorganize itself. This process, described as “forgetting” the seizure network, suggests that the treatment could evolve from a control mechanism into a functional cure.

The findings, published in the prestigious Annals of Neurology, were based on an evaluation of ten patients undergoing analysis for epilepsy surgery. The study demonstrated that the personalized targeting effectively reduced network excitability in these subjects.
This research is a flagship project of the Mayo Clinic’s Bioelectronic Neuromodulation Innovation to Cure (BIONIC) initiative. BIONIC is designed to accelerate the translation of engineering breakthroughs into clinical therapies. The study was also supported by the Tianqiao & Chrissy Chen Institute, highlighting the global interest in this neuro-engineering frontier.

How does personalized DBS differ from traditional Deep Brain Stimulation?
Traditional DBS places electrodes in the same anatomical spot for every patient. Personalized DBS maps the individual’s brain waves to find the specific “hub” in the thalamus that controls their unique seizure network, allowing for highly targeted stimulation.
Can brain stimulation cure drug-resistant epilepsy?
While traditional DBS controls symptoms, this new personalized approach aims to “rewire” the brain. By constantly disrupting the seizure network, researchers believe the brain can be retrained to “forget” the abnormal pathways, potentially leading to a cure.
What is the success rate of the new Mayo Clinic epilepsy treatment?
The current study evaluated the approach in 10 patients with promising results regarding network excitability reduction. Long-term efficacy rates will be determined in the next phase of trials involving permanent implants.
What to Watch For Next
- Long-Term Trials: Researchers will now follow patients who have received permanent DBS implants based on this personalized protocol to measure long-term seizure freedom.
- BIONIC Expansion: Expect the Mayo Clinic’s BIONIC initiative to apply this “network mapping” philosophy to other neurological conditions, potentially including Parkinson’s and depression.
- Regulatory Updates: If the larger trials replicate these early successes, look for the FDA to potentially review guidelines for DBS electrode placement in epilepsy patients.
