Transcranial Electrical Stimulation Targeting the Cerebellum for the Treatment of Refractory Temporal Lobe Epilepsy

This study is a single-center, observational study.This study applies transcranial alternating current stimulation to the cerebellum of patients with refractory temporal lobe epilepsy.For the recruited patients with refractory TLE (Temporal Lobe Epilepsy), they will undergo a 6-week treatment with tACS (transcranial alternating current stimulation) protocol (2mA, 10Hz, 20 minutes per side), following a schedule of treatment for 5 days - rest for 2 days - treatment for another 5 days, and then a reinforcement treatment once a week, completing a total of 14 treatments.Before treatment, at week 10, and at week 14, the frequency of epileptic seizures and the QOLIE-31 questionnaire scores will be recorded and assessed for the patients. EEG data and near-infrared spectroscopy (NIRS) brain functional imaging data will be collected before treatment and after two consecutive weeks of treatment. Magnetic resonance imaging (MRI) data will be acquired before treatment, after two consecutive weeks of treatment, and after six weeks of intensified treatment. Appropriate image processing methods and EEG processing methods will be utilized to analyze the changes in brain networks following tACS treatment, in order to explore the impact of tACS on the neural mechanisms of refractory temporal lobe epilepsy (TLE).
