Accelerated Intermittent Theta-Burst Stimulation Ameliorate Major Depressive Disorder by Regulating CAMKII Pathway

Major depressive disorder(MDD) is a complex and heterogeneous mental disorder. Repeated transcranial magnetic stimulation (rTMS), as a non-invasive neuroregulatory technique, has shown a promising function in the treatment of depression. Theta-burst transcranial magnetic stimulation (TBS) model significantly shortened the duration of physical therapy treatment, and iTBS under the accelerated model (The latter is referred to as aiTBS)showed promising therapeutic effect. However, whether aiTBS has a better and faster curative effect in the first untreated or recurrent unmedicated MDD patients and the mechanism of its alleviation of depressive symptoms remains unclarified. This project intends to verify changes in CAMKII levels, CAMKII molecules and GABA receptors in brain-derived exosomes in normal controls and patients who received sham, aiTBS and high-frequency (10Hz) stimulation respectively. Neuroimaging and TMS-EEG were used to pinpoint the target of stimulation and to record the changes of brain waves before and after treatment in real time. To clarify the neurobiological mechanism of aiTBS rapidly improving depression, and to provide a new strong evidence for clinical transcranial magnetic stimulation for accurate treatment of MDD patients.

Treatment and study plan

Sham stimulation

Device

The parameters in the sham arm will be as above with the internal randomization of the device internally switching to sham in a blinded fashion.

Accelerated intermittent theta burst stimulation

Device

Participants in the active stimulation group will receive the accelerated intermittent TBS to left DLPFC. The L-DLPFC will be targeted utilizing the neuronavigation system. Stimulation intensity will be standardized at 90% of RMT.

Stimulation will be delivered to the L-DLPFC using an NTK-TMS-II100 TMS device,is compatible with the Brainsight TMS navigation system.

High frequency stimulation

Device

Participants in the active stimulation group will receive the high frequnency stimulation to left DLPFC. The L-DLPFC will be targeted utilizing the neuronavigation system. Stimulation intensity will be standardized at 90% of RMT.

Stimulation will be delivered to the L-DLPFC using an NTK-TMS-II100 TMS device,is compatible with the Brainsight TMS navigation system.

Secondary outcomes

  1. Change in the score of THINC-it.

    Time frame: Baseline

    THINC-it is a computerized cognitive screening tool that is designed to assess cognitive function in adults. THINC-it stands for "THINking Clearly," and it includes a series of brief tests that evaluate several cognitive domains, including attention, working memory, executive function, and processing speed. The tool is administered on a tablet or computer, and it takes approximately 20 minutes to complete.

  4. Change in neuroimaging using functional magnetic resonance

    Time frame: Baseline

    Scanning functional magnetic resonance. Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that is used to measure changes in brain activity by detecting changes in blood flow. In the context of major depression, fMRI has been used to study changes in brain function that may be associated with the condition. Research using fMRI in major depression has shown that there are alterations in the activity of certain brain regions in people with the condition. Specifically, fMRI studies have identified changes in the activity of the prefrontal cortex, the amygdala, and the hippocampus in people with major depression. Overall, fMRI has provided valuable insights into the neural mechanisms underlying major depression, and may help to inform the development of new treatments for the condition.
