Can magnetic pulses sharpen the mind in schizophrenia?
NCT ID NCT07445620
First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This study compares two types of brain stimulation—accelerated theta burst and high-frequency TMS—against a sham (fake) treatment to see if they can improve cognitive problems like memory and attention in people with treatment-resistant schizophrenia. Ninety adults on clozapine will receive 20 sessions over 4 weeks. Researchers will measure thinking skills, social cognition, and brain activity changes up to 12 weeks later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial magnetic stimulation (TMS)
- What this could lead to
- If successful, this could point toward a non-drug way to improve cognitive symptoms like memory and attention in people with schizophrenia who haven't responded to other treatments.
- What could go wrong
- This is an early-stage study with only 90 participants, so results may not apply to everyone. The treatment is experimental and may not improve cognition more than a placebo.
