How genes and inflammation may raise risk for delirium and Alzheimer's in older adults

Brain Vulnerability in Delirium and Alzheimer’s Disease and Related Dementias: Intersection of Polygenic Risk and Inflammation

NIH-funded research Beth Israel Deaconess Medical Center · NIH-11237979

This project looks at whether older adults with higher genetic risk for Alzheimer's plus inflammation from events like surgery or infection are more likely to get delirium, faster memory decline, or dementia.

What this research studies

If you join, researchers will combine information about your genes (a polygenic risk score) with blood tests that measure inflammation to track changes in thinking and memory. You may be followed after events that raise inflammation, such as surgery or infection, using medical records and standard cognitive tests over time. The team will compare people with higher versus lower genetic risk to see whether inflammation more often leads to delirium or long-term cognitive decline in those with a 'vulnerable' brain. This builds on prior links between inflammation, delirium, and Alzheimer's but uses modern genetic scoring to try to pinpoint who is at greatest risk.

Who could benefit from this research

Good fit: Ideal candidates are older adults (typically age 65 and up), especially those who may undergo surgery or experience infections and who can provide blood samples and medical records for follow-up.

Not a fit: Younger people or those without available genetic or inflammation data, and people whose cognitive problems are due to non‑Alzheimer causes, are less likely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the work could help identify older adults at higher short- and long-term risk so clinicians can target prevention or closer monitoring when inflammation occurs.

How similar studies have performed: Previous studies have linked inflammation to delirium and certain genes (like APOE) to dementia risk, and polygenic risk scores have improved Alzheimer's prediction, but combining polygenic risk with inflammation to predict delirium and downstream dementia is relatively new.
