Investigating brain waste clearance and its link to postoperative delirium in elderly patients

Investigating the Link Between Preoperative Glymphatic Transport and Postoperative Delirium

Technical University of Munich · NCT06236854

This study is trying to see if problems with brain waste removal are linked to the risk of confusion after surgery in older patients aged 65 and up.

What this trial studies

This observational study aims to explore the relationship between glymphatic transport impairment and the risk of postoperative delirium (POD) in elderly patients aged 65 and older. By measuring glymphatic transport, the study seeks to identify preoperative factors that may predispose certain patients to develop POD following surgery. The research focuses on understanding how perioperative stressors may exacerbate existing vulnerabilities in the glymphatic system, potentially leading to cognitive decline and other complications. The findings could help in developing strategies to mitigate the risk of POD in susceptible patients.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients aged 65 and older who are fluent in German and have at least one risk factor for postoperative delirium.

Not a fit: Patients who are scheduled for neurological surgery or have pre-existing neurological impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved identification and management of patients at risk for postoperative delirium, enhancing recovery and reducing healthcare costs.

How similar studies have performed: While the specific approach of measuring glymphatic transport in relation to POD is novel, there is existing literature on the risk factors for POD that supports the relevance of this investigation.
