Assessing consciousness in brain-injured patients using fMRI and EEG

CONNECT-ME: CONsciousness in NEurocritical Care cohorT Study Using fMRI and EEG

Observational Rigshospitalet, Denmark · NCT02644265

This study is trying to see if new brain imaging techniques can help find out if patients with severe brain injuries are still aware, even if they can't communicate.

What this trial studies

This study aims to detect preserved consciousness in patients with acute brain injuries who are unable to communicate. By utilizing advanced technologies like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), the study seeks to identify patients who may be misclassified as being in a vegetative state. The approach focuses on cognitive tasks that patients can perform mentally, which may indicate their level of consciousness. This research is crucial for improving prognosis, treatment decisions, and resource allocation for these patients.

Who should consider this trial

Good fit: Ideal candidates for this study are non-responding patients with acute or sub-acute brain injuries, including those in a coma, vegetative state, or minimally conscious state.

Not a fit: Patients with severe pre-existing neurological deficits or those unable to undergo MRI due to contraindications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate assessments of consciousness in brain-injured patients, improving their treatment and care.

How similar studies have performed: Other studies have shown promise in using fMRI and EEG to assess consciousness, suggesting that this approach could be effective.
