Predict MDE Outcomes After MST
Study Details
Study Description
Brief Summary
This trial attempts to explore the treatment outcome of magnetic seizure therapy (MST) for major depressive episode. Half of the participants will receive MST, while the other half will receive electroconvulsive therapy (ECT).

Detailed Description
Magnetic seizure therapy (MST) is likely to be an alternative options to electroconvulsive therapy (ECT).
Widespread stimulation of cortical and subcortical regions is inevitable for ECT since the substantial impedance of the scalp and skull shuts most of the electrical stimulus away from the brain. Nevertheless, magnetic pulses are capable to focus the stimulus to a specific area of the brain because they can pass the scalp and skull without resistance. In Addition, electric current will penetrate into deeper structures, while magnetic stimulus are only capable to reach a depth of a few centimeters. As a consequence, MST are able to generate focus stimuli on superficial regions of the cortex while ECT can't, which may give MST the capability to produce comparable therapeutic benefits with the absence of apparent cognitive side effects.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: magnetic seizure therapy 12 treatment sessions of MST, three times per week. |
Device: Magpro X100 + Option
In addition to treatment as usual (TAU), participants were supposed to receive twelve sessions of MST in four weeks (three sessions per week)
|
| Active Comparator: electroconvulsive therapy 12 treatment sessions of ECT, three times per week. |
Device: ThymatronSystem Ⅳ Electroconvulsive System
In addition to treatment as usual (TAU), participants were supposed to receive twelve sessions of ECT in four weeks (three sessions per week)

Outcome Measures
Primary Outcome Measures
- changes in the 17-item Hamilton Depression Rating Scale (HAMD-17) [At baseline and 4-week follow-up]
The HAMD-17 score ranges from 0 to 52. A higher score indicates a worse outcome.
Secondary Outcome Measures
- changes in the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) [At baseline and 4-week follow-up]
- changes in the spectral power of the electroencephalogram (EEG) in square microvolt during resting state [At baseline and 4-week follow-up]
- changes in the spectral power of the electroencephalogram (EEG) in square microvolt during the auditory mismatch negativity task [At baseline and 4-week follow-up]
- changes in the spectral power of the electroencephalogram (EEG) in square microvolt during the facial recognition task. [At baseline and 4-week follow-up]
