Using emotional sounds to assess consciousness in critically ill patients
Official title: Emotional and Neutral Sounds for Neurophysiological Prognostic Assessment of Critically Ill Patients With a Disorder of Consciousness (DOC)
Run by Assistance Publique - Hôpitaux de Paris · NCT05740735 · Data updated 2026-11-12
This study is testing if critically ill patients can show signs of awareness by measuring their brain responses to hearing their name spoken by someone they know compared to a stranger.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include ICU patients with persistent disorders of consciousness following cardiac arrest, stroke, or head trauma.
✕Probably not a fit
Patients who are moribund, brain dead, or have known deafness will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to evaluate the neurophysiological responses of critically ill patients with a disorder of consciousness by comparing their reactions to emotional sounds of their own name spoken by a familiar voice versus a non-familiar voice. It focuses on measuring event-related potentials (ERPs), specifically the P300 response, to determine the prognostic value of these responses in assessing patient outcomes. The study is conducted in intensive care units and involves patients who have experienced cardiac arrest, stroke, or head trauma. By utilizing advanced neurophysiological techniques, the research seeks to improve the accuracy of consciousness assessments in these patients.
Why it matters
Potential benefit: If successful, this study could enhance the ability to predict recovery outcomes in critically ill patients with disorders of consciousness.
How similar studies have gone: While some studies have explored neurophysiological assessments in similar contexts, this specific approach using emotional sounds is relatively novel.
