Spinal fluid and blood tests to understand delirium and thinking problems after surgery

Examining CSF and Blood Biomarkers to Gain Insight into Postoperative Delirium and Neurocognitive Dysfunction

NIH-funded research Stanford University · NIH-11309642

This project looks at spinal fluid and blood markers from adults having surgery to learn why some develop delirium and longer-term thinking problems.

What this research studies

If I join, researchers will collect blood and cerebrospinal fluid (CSF) samples during and after surgery and measure markers like beta-amyloid, tau, signs of blood-brain barrier damage, and inflammation. They will take these measurements at multiple times to see how levels change over days to months. My thinking and memory will be tested before and after surgery and during follow-up to link the lab markers with changes in cognition. The team will combine the biological data with clinical information to look for patterns that explain who develops delirium or lasting cognitive problems.

Who could benefit from this research

Good fit: Ideal candidates are adults scheduled for surgery who can provide blood and CSF samples and agree to cognitive testing before and after their operation.

Not a fit: People who are not having surgery, cannot undergo lumbar puncture, or are unwilling to complete follow-up testing are unlikely to benefit or be eligible.

Why it matters

Potential benefit: This work could help doctors predict, monitor, or eventually prevent delirium and longer-term cognitive decline after surgery using blood or spinal fluid tests.

How similar studies have performed: Animal and some human studies support parts of the hypothesis, but collecting serial CSF around surgery in patients is relatively new and not yet widely tested.
