Magnetic seizure therapy （MST） is a new neuromodulation technique which is developed based on repetitive transcranial magnetic stimulation and electroconvulsive therapy （ECT）. The non-invasive， focused，and targeted stimulation provided by MST has the advantage of preserving cognitive functions while exerting a neuromodulatory effect. MST has been applied in intervention studies for various mental disorders such as depressive disorder，bipolar disorder，and schizophrenia，but further clinical research and evidence are needed. This review summarizes the mechanisms，current treatment procedure，clinical efficacy，and safety profile of MST.
