An interventional study of Electroencephalography (EEG) in Coma, sponsored by Hospices Civils de Lyon. Completed at 1 site in France. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-03.

Exposure to music improves cognitive function in 'healthy' participants and in brain-damaged patients. However, it is still difficult to understand what precisely in music causes a positive effect : are they emotional components, familiarity or preference which improve cognition or is there any specific effect of music? Moreover, it is not yet possible to characterize the neural and functional links between the brain systems solicited by music and those associated with other cognitive functions enhanced by music.
Finally, researches on brain-damaged patients have not exploited the potential effect of music on the level of alert and perceptual awareness, while this type of stimulation could be a valuable tool to improve cognition in patients with a disturbance of consciousness and alertness.
The main objective is to describe the impact of music on the brain's response to self-referential or neutral stimuli in brain-damaged patients with persistent consciousness disorder after a coma and in healthy participants.
138 studies on the registry are indexed under Coma; 35 are open to participants now.
This study's enrollment of 86 is close to the median of 85 across 77 interventional studies indexed under Coma.

Exclusion Criteria:
Electroencephalography (EEG) will be performed in patients in coma, in a vegetative state or in a minimally conscious state to assess the P300 response after different auditive stimulations
Other: Electroencephalography (EEG)
Electroencephalography (EEG) will be performed in healthy participants to assess the P300 response and medial prefrontal cortex activity after different auditive stimulations
Other: Electroencephalography (EEG)
EEG will be performed to assess brain activity in response to sounds of different nature, including music and the given name of the registered person
P300 response in brain-damaged patients
Improvement of the P300 response (increase in amplitude and / or a decrease in latency) to the first name pronunciation will be assessed in patients in coma, in a vegetative state or in a minimally conscious state, when it is preceded by a favorite or familiar sound (music, language, environmental noise) and / or a positive emotional connotation, compared to a control condition (unfamiliar sound and / or neutral emotional connotation). This improvement in brain response will be the sign of a more efficient categorization of patient's own name.
Time frame: 24 hours after inclusion
P300 response in healthy volunteers
Improvement of the P300 response (increase in amplitude and / or a decrease in latency) to a self-referential stimulation (eg first name pronunciation) compared to a non-self-referential stimulation (eg other name) will be assessed in healthy participants when it is preceded by a favorite or familiar sound (music, language, environmental noise) and / or a positive emotional connotation, compared to a control condition (sound unfamiliar and / or neutral emotional connotation)
Time frame: 24 hours after inclusion
P300 response in brain-damaged patients
Increase of the P300 response (increase in amplitude and / or a decrease in latency) to a self-referential stimulation (e.g. name pronunciation) will be assessed when the patient is awake (according to EEG measures and / or eye opening) compared to when the patient is asleep (according to EEG measures and / or eye closure).
Time frame: 24 hours after inclusion
Medial prefrontal cortex activity level in healthy volunteers
Increase of the level of activity measured in the medial prefrontal cortex will be assessed in healthy participants after a favorite or familiar sound (music, language, environmental noise) and / or a positive emotional connotation, compared to a control condition (unfamiliar sound and / or neutral emotional connotation).
Time frame: 24 hours after inclusion

Ran from Jun 2013 to primary completion in Oct 2019, 75 months.
Of 39 non-industry interventional studies with no phase under Coma, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 54. This study's 75 months is above that.
Counting every sponsor, half of 39 studies reached it within 39 months; a quarter within 17 and three quarters within 54.
