Brain metabolism may foretell Post-Surgery confusion in elderly diabetics
NCT ID NCT07369466
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow 154 older adults with type 2 diabetes who are scheduled for liver tumor surgery. Researchers will measure brain glucose metabolism using a PET scan before surgery and then check for delirium (sudden confusion) for a week after. The goal is to see if lower brain metabolism can predict who will develop delirium, which could lead to better monitoring and prevention strategies.
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 provide a brain scan-based way to identify older diabetic patients at high risk for delirium after surgery, enabling earlier preventive care.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks for a link between brain metabolism and delirium—it won't test any intervention. Results may not apply to all surgeries or patients.
