Brain wave test may reveal hidden thoughts in brain injury patients
NCT ID NCT01899924
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study tested whether brain wave recordings (event-related potentials) can detect cognitive processing in people with brain injuries, including those with altered consciousness. Researchers compared 320 patients and healthy adults using high-density EEG. The goal was to see if the brain responds to tasks even when the person cannot speak or move.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could improve how doctors assess hidden cognitive function in patients with brain injuries, even if they cannot respond outwardly.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to direct patient benefits, and results may not apply to all types of brain injury.
