Understanding how sepsis affects brain function in older adults

Official title: Neuroinflammatory mechanisms underlying sepsis-induced cognitive dysfunction

Funded at Vanderbilt University Medical Center · NIH-10835675 · Data updated 2026-11-12

This study is looking at how sepsis affects thinking and memory in older adults, especially how inflammation in the brain might cause long-lasting problems, and it aims to find ways to help improve brain function for those who have had sepsis.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults who have suffered from sepsis and are experiencing cognitive difficulties.

Less likely to help

Patients who are younger or have not experienced sepsis may not benefit from this research.

What this research studies

This research investigates the impact of sepsis on cognitive function in older adults, particularly focusing on how inflammation in the brain may lead to long-term cognitive impairments. The study aims to explore the role of microglia, the brain's immune cells, in causing memory and attention issues after sepsis. By using advanced animal models that better mimic the conditions of older adults, the researchers will assess how age and existing Alzheimer's-related changes in the brain influence recovery from sepsis. The findings could help identify new therapeutic targets to improve cognitive outcomes for affected patients.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments for cognitive dysfunction in older adults who have experienced sepsis.

How similar studies have gone: Previous research has shown that understanding neuroinflammatory responses can lead to significant advancements in treating cognitive dysfunction, suggesting this approach has potential for success.
