Summary

This study looks at whether analyzing brain-wave patterns (EEG) can help predict postoperative delirium—a state of confusion—in older adults after surgery. Researchers will collect EEG data before and during surgery from 90 patients aged 65 and older. The goal is to find a way to identify those at risk early, so doctors can intervene sooner.

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 lead to a simple brain-wave test to identify patients at risk of postoperative delirium before symptoms appear.
What could go wrong: This is a small, early-stage study (90 participants) focused on observation, not treatment. The method may not reliably predict delirium in broader populations.
