Investigating how blood-brain barrier changes affect cognitive recovery after surgery in older adults

Blood-Brain Barrier Disruption as a Biomarker for Perioperative Neurocognitive Disorder:Cognitive Recovery after Elective Surgery

NIH-funded research Rhode Island Hospital · NIH-11003835

This study is looking at how problems with the blood-brain barrier might affect thinking and memory in older adults after they have surgery, using a special brain scan to see if these changes can help predict issues like confusion or memory loss after the operation, with the hope of finding ways to keep their minds safe during surgery.

What this research studies

This research explores the relationship between blood-brain barrier (BBB) dysfunction and cognitive issues that can arise after surgery in older adults. By using a specialized brain imaging technique called water exchange index MRI (WEI-MRI), the study aims to identify how changes in the BBB may predict the risk of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). The research involves a longitudinal approach, tracking older patients undergoing major elective surgeries to better understand the impact of surgical stress on cognitive health. Ultimately, the goal is to develop strategies that enhance cognitive safety during surgery for elderly patients.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults, particularly those over 65 years, who are scheduled for major elective non-cardiac surgeries.

Not a fit: Patients who are younger than 65 or those undergoing non-elective surgeries may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved methods for preventing cognitive decline and enhancing recovery in older adults after surgery.

How similar studies have performed: Previous research has indicated that BBB dysfunction is linked to cognitive decline, suggesting that this approach may yield valuable insights, although the specific use of WEI-MRI in this context is relatively novel.
