Testing sound-based brain signals to predict recovery after severe brain injury
Part of Brain & nervous system, Heart & circulation, Mental health clinical trials.
This study checks how a brain responds to two kinds of sounds—neutral tones and emotional sounds—in people with a persistent disorder of consciousness after a serious event like stroke, head injury, or cardiac arrest. The goal is to see whether these brain “signal” tests can help doctors predict outcomes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are in an ICU after cardiac arrest, stroke, a specific type of brain bleed, or head trauma
- You have a persistent disorder of consciousness, at least 12 hours after sedation is stopped (or you already had a related brain-signal check)
- If you already had a prior brain-signal test, it showed only responses to neutral sounds (not emotional) more than 6 months ago
- You are not currently sedated, and you are not considered near-death
- You are able to hear sounds (no known deafness), and you are not brain-dead

Other trials that look related to this one.
This study looks at how the brain processes sounds in patients with disorders of consciousness, such as unresponsive wakefulness syndrome or minimally conscious state. It may help doctors better understand these conditions and improve care.
This trial tests whether combining music with gentle electrical brain stimulation can improve symptoms after a neurologic event, such as language and attention problems. It’s meant for adults who are living with effects of stroke and certain levels of reduced awareness.
This trial is testing a brain function evaluation system to help understand and possibly improve care for people with disorders of consciousness caused by brain injury, stroke, or lack of oxygen. It is for both acute (recent) and prolonged (lasting) cases.
This trial studies a device and plan to assess brain function and deliver an intervention in people who are in a coma, minimally conscious state, or unresponsive arousal state after brain injury, stroke, or lack of oxygen. If you qualify, it may help doctors understand and potentially improve brain function over time.
This study looks at different ways to predict how people with severe disorders of consciousness might recover after a brain injury. It may help doctors better estimate prognosis and improve care planning.
This trial studies memory abilities in people who are unconscious due to a brain injury. It compares unconscious patients, conscious patients in intensive care, and people who have recovered consciousness after being unconscious. Participation involves memory testing and may help us understand how the brain recovers.
