A Safety, Tolerability, and Preliminary Efficacy of Low-intensity Focused Ultrasound Neuromodulation in Patients With Drug-resistant Epilepsy

The study aims to demonstrate the safety and preliminary efficacy of LIFU neuromodulation in DR-TLE patients, showing its ability to decrease targeted neuronal activity and alleviate epileptic seizures. Patients diagnosed with epilepsy who meet all eligibility criteria may participate in this study by providing informed consent, either in person or through their legal representative. Eligible patients will undergo a 2-month baseline observation screening period and will be asked to keep a 8-week seizure diary. This diary will serve as a baseline prior to treatment and will continue to be recorded throughout the treatment and follow-up period. This study will enroll a maximum of 8 eligible patients through competitive enrollment. Patients will receive a total of 6 FUS treatments over 3 consecutive weeks using assigned ultrasound exposure doses generated by the NaviFUS System. Following treatment, there will be a 12-week follow-up period. Patients will be allowed concomitant use of anti-seizure medications (ASMs) throughout the whole study period.
