Summary

This study tests whether high-frequency magnetic stimulation (rTMS) can reduce auditory hallucinations in people with schizophrenia. Unlike standard low-frequency treatment that takes 15 days, this approach uses 20 Hz stimulation over just 2 days, guided by brain scans for precision. 72 participants will receive either real or sham treatment to see if it safely and effectively lessens the voices they hear.

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) device
What this could lead to
If it works, this could offer a faster, more targeted way to reduce auditory hallucinations in people with schizophrenia, potentially shortening treatment from weeks to days.
What could go wrong
This is a mid-stage trial with only 72 participants, so results may not apply to everyone. The treatment is still experimental, and there is a small risk of seizure or headache.
