Summary

This study will use brain electrodes (SEEG) and breathing monitors in 20 adults with drug-resistant epilepsy to map which brain areas control breathing during a challenge. The goal is to understand why some patients experience fatal breathing arrest after seizures (SUDEP). No treatment is tested—this is a knowledge-gathering study.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could reveal which brain regions are critical for breathing control during seizures, pointing toward future ways to predict or prevent SUDEP.
What could go wrong: This is a very early, small observational study (20 people) that only maps brain activity—it does not test any treatment. Results may not lead directly to clinical changes.
