Brain waves reveal: do unresponsive patients hear us in their final days?
NCT ID NCT05091632
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses a brain wave test (EEG) to check if cancer patients who seem unresponsive in their last days can still hear or feel. Researchers will measure brain activity when sounds or words are played. The goal is to help families and doctors understand what patients may experience, improving care and decisions at the end of life.
