Brain waves under the spotlight: a new clue to cyclic vomiting?
NCT ID NCT05256160
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This study uses a non-invasive brain stimulation technique called transcranial magnetic stimulation (TMS) to compare brain activity in people with cyclic vomiting syndrome (CVS) and healthy volunteers. The goal is to see if there are differences in cortical excitability—how easily the brain's motor cortex responds to stimulation. Researchers will measure brain responses and heart rate variability to explore potential underlying mechanisms of CVS.
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) paired-pulse assessment
- What this could lead to
- If differences are found, it could point toward new ways to understand or treat cyclic vomiting syndrome.
- What could go wrong
- This is an exploratory study, so it may not find clear differences, and results may not lead to treatments.
