Clinical Trial Summary

This study aims to compare the efficacy and safety profile of Magnetic Seizure Therapy and Electroconvulsive therapy.


Clinical Trial Description

Magnetic seizure therapy (MST) is a novel, experimental therapeutic intervention, which combines therapeutic aspects of electroconvulsive therapy (ECT) and transcranial magnetic stimulation, in order to achieve the efficacy of the former with the safety of the latter. While ECT remains the most efficacious treatment available for severe and treatment-resistant depression, it is hampered by its side effect profile, specially cognitive deficits, which albeit transitory might be particularly distressing for patient, not to mention the stigma that still clings to this method. MST employs high frequency magnetic pulses applied to the head to the patient in order to induce generalized epileptic activity, thus emulating the core feature of ECT. Though distributed over a large area, such pulses do not penetrate deeper areas of the brain, therefore sparing deeper areas such as the hippocampi, which are crucial for memory encoding. The goal of this study is to compare the antidepressant action of MST to ECT, using a non-inferiority approach. It also aims to compare the cognitive side effects profile of both interventions, as well as investigate possible neuroimaging changes and response predictors before and after treatments. ;
