Can a gentle brain current silence voices that medication Can't?
NCT ID NCT04352569
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial tests whether transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, can reduce auditory hallucinations in people with schizophrenia who haven't found relief from antipsychotic medications. Participants receive either real tDCS or a placebo (sham) stimulation, with two sessions per day for two weeks. The study measures changes in hallucination severity and overall symptoms to see if this approach could be a helpful addition to current treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique
- What this could lead to
- If effective, tDCS could offer a new, non-drug option to reduce distressing auditory hallucinations in people with schizophrenia who haven't responded to antipsychotics.
- What could go wrong
- This is a small, early-stage trial, so results may not be conclusive or widely applicable. tDCS is generally safe but may cause mild discomfort or tingling at the stimulation site.
