Predict MDE Outcomes After MST

Research on the Prediction of Clinical Response to Magnetic Seizure Therapy for Patients With Major Depression Episode

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).

Study Overview

• Status: Completed
• Conditions: Major Depressive Episode
• Intervention / Treatment: Device: Magpro X100 + Option; Device: ThymatronSystem Ⅳ Electroconvulsive System

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
changes in the 17-item Hamilton Depression Rating Scale (HAMD-17)	The HAMD-17 score ranges from 0 to 52. A higher score indicates a worse outcome.	At baseline and 4-week follow-up

Secondary Outcome Measures

Outcome Measure	Time Frame
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
