Sponsor

Centre for Addiction and Mental Health

Enrollment

80 participants

Start Date

Apr 22, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

This trial aims to assess the clinical effects and tolerability of Magnetic Seizure Therapy (MST) as an alternative to electroconvulsive therapy (ECT) for Treatment Resistant Schizophrenia (RS).


Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is testing Magnetic Seizure Therapy (MST) as a treatment for schizophrenia that has not responded well to antipsychotic medications. MST uses a focused magnetic field to induce a brief, controlled brain seizure under anesthesia, similar to electroconvulsive therapy (ECT) but with fewer side effects. **You may be eligible if...** - You are 18 or older with a diagnosis of schizophrenia or schizoaffective disorder for at least 2 years - You have tried at least 2 antipsychotic medications at adequate doses for at least 6 weeks each, without sufficient improvement - Your symptoms are at least moderately severe based on a standard rating scale - You are currently an inpatient or outpatient and can give informed consent **You may NOT be eligible if...** - You have a metal implant in your brain or body that is incompatible with magnetic therapy - You have a seizure disorder or other neurological conditions that make this procedure unsafe - You are pregnant - You have significant heart conditions that increase anesthesia risk Talk to your doctor to see if this trial is right for you.

Interventions

DEVICEMagnetic Seizure Therapy (MST)

MST treatment will be administered using the MagPro MST with a Cool TwinCoil over the frontal cortex in the midline position using 100 Hz stimulation at 100% machine output. Seizure threshold will follow prior protocols used for frontal MST. Patients will receive care and be managed by anaesthesia as per standard ECT practice.

DEVICEElectroconvulsive Therapy (ECT)

In the ECT arm treatment, the MECTA spectrum 5000Q or MECTA sigma machine will be used. The ECT determination of seizure threshold and the adjustment of energy at subsequent sessions will be based on a standard published protocol. All participants will receive RUL-UB ECT at six times the seizure threshold. Patients will receive care and be managed by anaesthesia as per standard ECT practice.
