Zapping the brain without surgery: a new hope for Tough-to-Treat epilepsy
NCT ID NCT06708143
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This study tests whether a noninvasive technique called temporal interference (TI) stimulation can reduce seizures in people aged 6 to 60 with drug-resistant epilepsy. Researchers apply TI stimulation to deep brain areas using external electrodes, aiming to calm overactive circuits without surgery. The main goal is to see if seizure frequency drops by at least half during the treatment period.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- temporal interference (TI) stimulation
- What this could lead to
- If it works, this could offer a noninvasive alternative to brain surgery for controlling seizures in people with drug-resistant epilepsy.
- What could go wrong
- This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The treatment may not reduce seizures enough to be clinically meaningful.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants are between the ages of 6 -60 years of age. * Patients must be clinically evaluated as having drug resistant epilepsy. * Persistence of disabling seizures at least 2 times per months or greater. * Informed consent signed. Exclusion Criteria: * Psychogenic non-epileptic seizures within 12 months; * Presence of implanted electrical stimulation medical device anywhere in the body (e.g., pacemaker, spinal cord stimulator, responsive neurostimulation) or any metallic implants in the head (e.g., aneurysm clips, cochlear implants). Note: Vagal nerve stimulators are allowed if the parameter remains stable for at least 3 months prior to the screening visit; * Risk factors that would put the participant at risk for intraoperative or postoperative bleeding. (e.g., coagulation abnormalities, etc.) or the need for chronic anticoagulation or antiplatelet aggregation medications; IQ \< 55 or severe cognitive dysfunction, unable to complete the study; Diagnosed with a progressive neurological disorder (including progressive Rasmussen's encephalitis, etc.); * Diagnosed with a severe neuropsychiatric disorder such as dementia, major depression (admission to a psychiatric specialty/hospital within 5 years or any suicidal or self-injurious tendencies), schizophrenia, or neurodegenerative disorders; * Diagnosed with other serious physical disorders, internal diseases or severe abnormalities in liver or kidney function; Pregnant, or planning to pregnant within 2 years; Participation in another clinical study within 3 months; Not suitable for enrollment as assessed by the multidisciplinary team of the center.
