Mayo Clinic's AI-Driven Deep Brain Stimulation Shows Promise for Drug-Resistant Epilepsy

Mayo Clinic study highlights a new approach to treating drug-resistant epilepsy

Mayo ClinicApr 7 2025 A study published in Brain Communications highlights a new approach to treating drug-resistant epilepsy. Researchers at Mayo Clinic have developed an innovative deep brain stimulation (DBS) platform that was used to not only reduce seizures, but also improve memory and sleep - two common challenges for patients with epilepsy. Epilepsy, a seizure disorder that affects about 50 million people worldwide, often disrupts memory, emotions and sleep. Many cases are drug-resistant, leaving people with limited treatment options. Researchers at Mayo Clinic found that low-frequency DBS not only reduced seizures, but it also improved memory and sleep. "Using an implanted investigational device, the team continuously monitored brain activity with AI-driven seizure and sleep tracking," says Gregory Worrell, M.D., Ph.D., Mayo Clinic neurologist and co-lead author of the study. "A cloud-based platform simultaneously assessed participants' behavior, memory and mood at home. This real-time data enables precise tuning of stimulation settings, maximizing benefits while minimizing side effects." By using an implanted device that continuously monitors brain activity, we can detect seizures more accurately than patient-reported diaries in order to optimize deep brain stimulation in real-time and improve treatment." Vaclav Kremen, Ph.D., Mayo Clinic researcher and co-lead author of the study The researchers monitored five patients with temporal lobe epilepsy throughout their DBS treatment. The system allowed patients to track their brain activity and symptoms remotely, providing doctors with detailed, real-world data to fine-tune treatments. This technology could lead to more effective treatments for drug-resistant epilepsy and could be expanded to treat other neurological and psychiatric disorders. "Our study demonstrates the potential of emerging neurotechnology to treat human disease," says Jamie Van Gompel, M.D., Mayo Clinic neurosurgeon and co-author of the study. "Combining neuroscience, engineering and artificial intelligence, our work is paving the way for more personalized and effective treatments for epilepsy and other brain disorders," says Dr. Worrell. The study was supported by the National Institutes of Health - National Institute of Neurological Disorders and Stroke, Defense Advanced Research Projects Agency, and the CLARA project, which has received funding from the European Union's Horizon Europe research and innovation program. The implanted devices were donated by Medtronic as part of the National Institutes of Health Brain Initiative Public-Private Partnership. Mayo Clinic
