Investigating how IL-6 affects cognitive decline after surgery in older adults and those with Alzheimer's disease

Official title: IL-6 Trans-signaling increases vulnerability to Postoperative Cognitive Decline in Aging and Alzheimers Disease

Funded at University of California, San Francisco · NIH-11187149 · Data updated 2026-11-12

This study is looking at how a substance called IL-6 might make it harder for older adults and people with Alzheimer's to think clearly after surgery, and it hopes to find ways to lower this risk by blocking IL-6 during and after surgery.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults and individuals diagnosed with Alzheimer's disease who are scheduled for surgical procedures.

Less likely to help

Patients who are younger than 21 years old or do not have cognitive decline or Alzheimer's disease may not benefit from this research.

What this research studies

This research focuses on understanding how a specific inflammatory cytokine, IL-6, may increase the risk of cognitive decline following surgery in older adults and individuals with Alzheimer's disease. By using animal models, the study aims to explore the mechanisms behind postoperative neurocognitive disorders (PNDs) and how IL-6 trans-signaling contributes to these conditions. The researchers will assess the levels of IL-6 in the brain during the perioperative period and evaluate whether blocking this signaling pathway can reduce the risk of cognitive decline. This approach could lead to new strategies for protecting vulnerable patients during and after surgical procedures.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing cognitive decline in older adults and those with Alzheimer's disease after surgery.

How similar studies have gone: Previous research has indicated that targeting inflammatory pathways may help mitigate cognitive decline, suggesting potential success for this approach.
