November 21, 2025- Mayo Clinic researchers have developed a new, personalized approach to deep brain stimulation (DBS) for people with drug-resistant epilepsy. By mapping each patient’s unique brain wave patterns, the method allows physicians to target the precise area in the brain where stimulation is most effective, moving beyond the traditional one-size-fits-all approach.
DBS involves implanting electrodes in the brain to deliver electrical pulses that help prevent and control seizures. While effective, DBS is typically administered with electrodes placed in the same brain region across most patients. Mayo Clinic physician-scientists are now tailoring the treatment to an individual’s seizure network before DBS placement.
Ten patients received this personalized approach while being evaluated for epilepsy surgery. The next phase of research will follow those who have since received permanent DBS implants using this personalized approach.
