Efficacy and Safety of Transcranial Temporal Interference Stimulation for Depression

27 de maio de 2026 atualizado por: Yonggui Yuan

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.

Visão geral do estudo

Descrição detalhada

Major depressive disorder (MDD) is a common and disabling mental disorder. Although medication, psychotherapy, and established brain stimulation methods can help many people with MDD, some participants still have insufficient improvement. Transcranial temporal interference stimulation (tTIS) is a non-invasive brain stimulation technique that may allow modulation of deeper brain regions or pathways. This study is designed to evaluate whether tTIS can improve depressive symptoms in adults with MDD, assess its safety, and explore potential neuroimaging mechanisms.

This is a single-center, randomized, double-blind, sham-controlled clinical trial conducted at Zhongda Hospital, Southeast University. Eligible participants with MDD will be randomly assigned in a 1:1:1 ratio to one of three groups: active tTIS targeting the left anterior limb of the internal capsule (ALIC), active tTIS targeting the left subgenual anterior cingulate cortex (sgACC), or sham tTIS. The sham stimulation will be designed to provide sensory feedback similar to active stimulation while maintaining blinding.

Participants with MDD will receive 10 treatment sessions over 5 consecutive days, with two 20-minute sessions each day. Clinical symptoms and safety will be assessed at baseline, after treatment, and during follow-up. The main clinical outcome is the change in the 24-item Hamilton Depression Rating Scale (HAMD-24) total score from baseline to after treatment. Secondary outcomes include follow-up changes in depressive symptoms, response and remission rates, anxiety symptoms, anhedonia, psychosomatic symptoms, side effects, and adverse events.

Multimodal 5.0T brain magnetic resonance imaging (MRI) will be collected from participants with MDD before and after treatment. MRI measures will include structural imaging, resting-state functional imaging, and diffusion imaging. These data will be used to explore changes in brain structure, functional connectivity, and diffusion-related measures after tTIS, and to identify potential imaging biomarkers related to treatment response.
