Zapping the brain to silence hallucinations: small study shows promise
NCT ID NCT05165654
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested whether a mild electrical current applied to a specific brain region (the right superior temporal sulcus) could reduce hallucinations in 12 adults with psychosis. Participants received transcranial electrical stimulation while researchers measured changes in hallucination severity and brain activity. The goal was to see if this noninvasive approach could improve sensory integration and lessen hallucinations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcranial electrical stimulation
- What this could lead to
- If it works, this could point toward a noninvasive brain stimulation treatment to ease hallucinations in people with psychosis.
- What could go wrong
- This is a very small, early study with only 12 participants. It may not show clear benefits, and the effects may not last or apply to everyone.
