Magnetic Seizure Therapy for Psychotic Disorders

November 24, 2025 updated by: Jijun Wang, Shanghai Jiao Tong University School of Medicine

Accelerated 100Hz Magnetic Seizure Therapy for Psychotic Disorders

This trial aims to evaluate the efficacy and safety of Magnetic Seizure Therapy (MST) as an augmentation of antipsychotic medications for psychosis.

Study Overview

Detailed Description

Psychosis is recognized as one of the largest contributors to nonfatal health loss, and substantial portion of patients exhibit resistance to antipsychotics, emphasizing the need for exploring non-pharmacological treatments. In clinical practice, Electroconvulsive therapy (ECT) has been shown to be generally effective in psychosis, but its clinical use sometimes is limited by its cognitive side effects. Magnetic Seizure Therapy (MST) is a novel modification of electroconvulsive therapy (ECT). MST offers the advantages of milder side effects on cognition, a quicker return of orientation, and a shorter duration of post-ictal confusion. A few studies have studied the antipsychotic effect of MST. Therefore, the present study will plan to perform a clinical trial to compare the efficacy of MST treatment plus antipsychotics to antipsychotic medications alone among psychotic disorders in acute phase. In addition, whether MST treatment plus antipsychotics will bring a quicker efficacy response than antipsychotic medications alone is also of important clinical significance. The present trial will plan to administer 10 sessions of MST in 2 weeks, in which the patients will be randomly allocated to either receiving MST+medications or receiving medications alone. After the 2 week's research intervention, all patients will be switched to clinical routine management, but kept under masked clinical assessment for 4 weeks.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Magnetic seizure therapy plus antipsychotics

The patients will receive antipsychotic drugs plus MST during the first 2 weeks.

A TwinCoil of MagPro XP will be positioned centrally over the frontal cortex in the midline position. The output power of MagPro XP is set to 100%, and stimulation frequency is 100 Hz. For MST titration, the first step is given at a 5-second train duration; if there is no seizure, the duration is increased to 10 seconds with a maximum limit of 10 seconds. The subsequent MST treatment will be maintained at 10 seconds. This procedure will be carried out under anesthesia.

A total of up to 10 treatments will be administered to participants, usually five times a week, for 2 weeks.

The seizure is induced by Magnetic stimulator of MagPro MST(XP),MagVenture A/S, Farum, Denmark. It is administered in combinations with antipsychotic medications
Other Names:
  • Seizure therapy
Active Comparator: antipsychotic drugs
The patients will receive second-generation antipsychotic drugs without MST or ECT during the first 2 weeks.
It mainly includes second-generation antipsychotic medications, such as olanzpine, risperidone, aripiprazole, quetiapine, amisulpride, etc, but except clozapine.
Other Names:
  • antipsychotics
