Talking back to voices: CBT shows promise for schizophrenia hallucinations
NCT ID NCT07524868
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested whether adding cognitive behavioral therapy (CBT) to standard medication (risperidone) could reduce auditory hallucinations and inflammation in 50 people with schizophrenia. Participants either received CBT plus medication or medication alone. The goal was to see if CBT helps with distressing voices and lowers a blood marker of inflammation called NLR.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cognitive Behavioral Therapy (CBT)
- What this could lead to
- If it works, this could point toward a way to ease distressing voices and reduce inflammation in people with schizophrenia who still hear voices despite medication.
- What could go wrong
- This is a small, completed study with only 50 people, so results may not apply to everyone. CBT requires time and effort, and not all patients may benefit.
