Efficacy and Safety of Transcranial Temporal Interference Stimulation for Depression
Sponsor: Yonggui Yuan
Summary
The goal of this clinical trial is to learn whether transcranial temporal interference stimulation (tTIS) can help treat major depressive disorder (MDD) in adults. The study will also learn about the safety of tTIS and explore how it may affect brain structure and brain function. The main questions it aims to answer are whether active tTIS lowers depression symptom scores more than sham stimulation after treatment, and what medical problems or side effects participants have during or after tTIS. Researchers will compare active tTIS targeting the left anterior limb of the internal capsule, active tTIS targeting the left subgenual anterior cingulate cortex, and sham stimulation. Sham stimulation is designed to feel similar to real stimulation but does not provide the same active treatment. Participants with MDD will be randomly assigned to one of the three groups. They will receive two 20-minute treatment sessions each day for 5 days. They will complete depression, anxiety, pleasure, psychosomatic symptom, and safety assessments before treatment, after treatment, and during follow-up. They will also have brain magnetic resonance imaging scans before and after treatment.

Interventions
Active Transcranial Temporal Interference Stimulation Targeting Left ALIC
Participants in this arm will receive active transcranial temporal interference stimulation (tTIS) targeting the left anterior limb of the internal capsule (ALIC). The stimulation target will be individualized based on each participant's magnetic resonance imaging data. The difference frequency will be 130 Hz. Each session will last 20 minutes, twice daily for 5 consecutive days, with a 30-minute interval between sessions.
Active Transcranial Temporal Interference Stimulation Targeting Left sgACC
Participants in this arm will receive active transcranial temporal interference stimulation (tTIS) targeting the left subgenual anterior cingulate cortex (sgACC). The stimulation target will be individualized based on each participant's magnetic resonance imaging data. The difference frequency will be 130 Hz. Each session will last 20 minutes, twice daily for 5 consecutive days, with a 30-minute interval between sessions.
Sham Transcranial Temporal Interference Stimulation
Participants in this arm will receive sham transcranial temporal interference stimulation (tTIS) using the same type of device as active stimulation. Sham stimulation will provide sensory feedback similar to active stimulation to help maintain masking, but it will not deliver the same active treatment dose. Each session will last 20 minutes, twice daily for 5 consecutive days, with a 30-minute interval between sessions.
