About

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.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

90 participants in 3 patient groups

Placebo stimulation

Sham Comparator group

Description:

The sham group of MDD will receive sham rTMS stimulation.

Treatment:

Device: sham stimulation

accelerated intermittent theta burst stimulation

Active Comparator group

Description:

Stimulation site: According to the localization of neural orientation navigation system, magnetic resonance data was read in Brainsight software, and three-dimensional brain reconstruction was carried out. The stimulation target was located in the coordinates of Montreal Neurological Institute (MNI), which was located in the left dorsolateral prefrontal cortex BA46(-44, 40, 29).The treatment intensity was 100% exercise threshold, and a TBS stimulus series was stimulated for 2 seconds, including 10 times of 3 intra plexus stimuli of 50Hz and 5Hz intraplexus stimuli, 10s of interval, repeated 60 times, that is, a total of 1800 pulses per treatment, 10 times a day, 50 minutes interval, a total of 18000 pulses per day, continuous for 5 days.
