Could magnetic pulses lift depression in schizophrenia?
NCT ID NCT05671185
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether repetitive transcranial magnetic stimulation (rTMS) can reduce depression in people with schizophrenia. About 180 adults will receive rTMS to the left prefrontal cortex. Researchers will measure changes in mood, thinking, and other symptoms over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation (rTMS)
- What this could lead to
- If it works, this could offer a non-drug option to treat depression in people with schizophrenia, potentially reducing suicide risk and improving quality of life.
- What could go wrong
- This is an early-stage study with no phase, so results are uncertain. The effect may be small, and not all participants may benefit. rTMS is generally safe but can cause headache or scalp discomfort.

Inclusion Criteria: * Age ≥ 20 years * Able to give informed consent * Diagnosed with schizophrenia or schizoaffective disorder according to DSM-5 * Has a score ≥ 7 on Calgary depression scale for schizophrenia * The principal psychotropic agents are not changed within one month of the first session of rTMS Exclusion Criteria: * DSM-5 defined substance use disorder (excluding tobacco) in the past 3 months * Have clinically relevant cognitive impairment (e.g., delirium, intellectual disability or MMSE \< 15) * With electronic and/or magnetic implants (e.g. pacemaker, implantable cardioverter defibrillator \[ICD\], cerebral shunts, cochlear implant, etc.) * With metallic or mechanic fragments (e.g., screws, plates, stents, clips, etc.) * Pregnant, or has a pregnancy plan within 3 months * With any known or history of neurological conditions including cerebral vascular accidents, epilepsy (or epileptiform waves detected by EEG prior to the first session of rTMS), brain tumor or space occupying lesion * Received rTMS or iTBS treatment within 3 months * Has a clinically significant abnormality on the screening examination that might affect safety, study participation, or confound interpretation of study results
