Temporal interference (TI) stimulation is a new neuromodulation method. Compared with traditional neuromodulation therapy, TI has deep targeting and focusing, and it has been confirmed to modulate sleep, cognition, and movement disorders. Recent study shown that TI stimulation targeting the hippocampus could significantly reduce epileptiform discharges, but its efficacy on seizures was still unclear. Therefore, the aim of this study is to observe the therapeutic effect of TI stimulation targeting the hippocampus in patients with refractory temporal lobe epilepsy (TLE) for 5 days, and to provide support for clinical trials of non-invasive treatment of refractory TLE.
