Overnight Temporal Interference Stimulation for Temporal Lobe Epilepsy
Official title: Overnight Temporal Interference Stimulation of Bilateral Hippocampi to Reduce Epileptogenic Biomarkers and Improve Sleep in Temporal Lobe Epilepsy
Run by Duke University · NCT07434986 · Data updated 2026-11-12
This study tests whether overnight, non-invasive temporal interference stimulation to the hippocampus can reduce seizure-related brain activity and improve sleep in adults with drug-resistant temporal lobe epilepsy.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18-70 with focal drug-resistant temporal lobe epilepsy who can participate in in-lab overnight PSG/EEG monitoring and adhere to the medication stability requirement.
✕Probably not a fit
Participants with generalized epilepsy, unstable psychiatric conditions, or implants incompatible with TI may not benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults with drug-resistant temporal lobe epilepsy undergo in-lab overnight sleep monitoring with EEG while receiving several nights of TI stimulation targeting both hippocampi. Each participant experiences nights without stimulation, nights with active stimulation, and a follow-up night after stimulation to see if any changes persist. The study compares EEG seizure activity and sleep quality during stimulated versus non-stimulated nights. Researchers also collect brief cognitive questionnaires and memory tasks to explore effects on thinking and memory. The approach uses non-invasive brain stimulation in a tightly controlled overnight setting at a single Duke-led site with international collaboration.
Why it matters
Potential benefit: If successful, TI stimulation could reduce seizure-related brain activity during sleep and improve sleep quality for people with temporal lobe epilepsy.
How similar studies have gone: Prior attempts with non-invasive brain stimulation for epilepsy have shown mixed but encouraging signals; this study applies a novel overnight TI approach focused on the hippocampi.
