The Study About Mechanism of Transcranial Magnetic Stimulation Treatment of Patients With Depression Using Multimodal Magnetic Resonance Imaging

Depression is the most common psychiatric condition and a important public health concern in society. But medications for depression don't work as well as people expected and cause serious side-effects. Transcranial magnetic stimulation (TMS) is a noninvasive electrical stimulation treatment for depression, which has been approved by the FDA and added to the Guidelines for the Treatment of Depression in China. Despite the effect of the treatment is clear ,the TMS target,the neural circuit which plays a role in TMS and its mechanism remain unknown now. TBS target and effective site may be not in the same position. A large number of previous studies demonstrate the advantages and application prospects of different techniques of magnetic resonance (MR)in the study of pathogenesis of depression. Based on the results of previous research supported by the National Natural Science Foundation of China,the National Key Technology Research and Development Program of China during the "10th Five-Year Plan" and New Health Care and New technology. project team puts forward the idea of joint use of brain structure imaging of MR ,Diffusion Tensor Imaging (DTI) and resting-state functional MRI (fMRI) with different analysis methods to conduct a comprehensive study. The study is focused on the effects of TBS treatment on brain structure network, fiber connectivity network and functional connectivity network ,and nodes affected by it. Then we make further investigation about the mechanism of TMS treatment. The research will provide not only help for studying the pathogenesis of depression but also more reliable targets of next TMS treatment.

Study Overview

Detailed Description

The advantages of 3D T1 WI are thin slice scan,no interval, scanning fast and three-dimension reconstruction in any orientation compared with 2D SE. It is not easy to miss small lesions, and shows normal anatomy and lesions more objectively and more accurately.

Doppler tissue imaging (DTI) can reflect white matter fiber so that can be used to determine whether the various diseases affect nerve cell connections.

Arterial spin labeling (ASL) is non-drug perfusion imaging and completely noninvasive technology which can reflect brain perfusion better.

Resting-state functional MRI (fMRI) is used to located the abnormal brain regions whose activity is consistent with dorsolateral prefrontal cortex (DLPFC) by the abnormal resting spontaneous brain activity in patients with depression and the abnormal functional connectivity network.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: TMS treatment group
In the Transcranial magnetic stimulation (TMS) treatment group patients with severe depression receive rTMS treatment without drug treatment.
TMS treatment group is treated with TMS for 20-40 minutes a time, 5 times a week. The stimulation parameters were 20 Hz and 80% MT. Each stimulation continues for 2 seconds, and the interval time of stimulation is 58 seconds.
ACTIVE_COMPARATOR: medication group
In the medication group patients with severe depression are treated with anti-depressants.
Medication group is treated with anti-depression for 6 weeks. The drugs and their doses belong to the first-line treatment for depression in the current guideline .
NO_INTERVENTION: healthy control group
The control group don't accept intervention and treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hamilton Depression Scale-17(HAMD-17)
Time Frame: Difference at HAMD-17 between day 1,week 2 and week 4.
HAMD-17 are to evaluate the severity degree of depression and the clinical effectiveness for treatment of depression.HAMD-17 scores range in 0-52 points.Total score which is between 7 and 16 means that volunteer may be with depression.Total score which is between 17 and 23 means that volunteer certainly is with depression.Total score which is more than 23 means that volunteer is with severe depression.
Difference at HAMD-17 between day 1,week 2 and week 4.
Multimodal Magnetic Resonance Imaging
Time Frame: Difference at Multimodal Magnetic Resonance Imaging between day 1,week 2 and week 4.
Multimodal Magnetic Resonance Imaging include 3D-T1, ASL, DTI, resting-state functional MRI, etc.these show the Brain changes.
Difference at Multimodal Magnetic Resonance Imaging between day 1,week 2 and week 4.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Global Impression.(CGI)
Time Frame: Difference at CGI between day 1,week 2 and week 4.
CGI is to evaluate the severity degree of depression to estimate whether patients are in accordance with inclusion criteria which concludes severty of illness (si),global improvement (gi) and efficacy index (ei).Si scores range in 0-7 points.Gi scores range in 0-7 points.Ei scores range in 0-4.00 points.
Difference at CGI between day 1,week 2 and week 4.
Wisconsin Card Sorting Test (WCST)
Time Frame: Difference at WCST between day 1,week 2 and week 4.
WCST is to to evaluate the cognitive function of volunteers.Total score which is less 69 means that volunteer suffers from mental deficiency.
Difference at WCST between day 1,week 2 and week 4.
