Summary

This study looks at how brain wave (EEG) patterns change during anesthesia in older adults having joint or spine surgery. Researchers will track whether these patterns relate to postoperative delirium, a common confusion after surgery. About 375 patients aged 60 and older will have EEGs recorded before, during, and after surgery, and be checked for delirium using a simple test. The goal is to find early warning signs that could help doctors prevent or manage delirium.

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 help doctors identify patients at risk of postoperative confusion earlier, potentially leading to better monitoring and care.
What could go wrong: This is an observational study, not a treatment trial. It will not directly prevent or cure delirium, and results may not apply to all surgical patients.
