NIH-funded research R21 grant

Understanding pain in older adults and its causes

Official title: Pain in the Elderly: Role of Hyperalgesic Priming

Funded at University of California, San Francisco · NIH-11184521 · Data updated 2026-11-12

This study is looking into why older adults often feel more pain than they should, by using aged rats to understand how past injuries and inflammation can make their pain receptors more sensitive, with the hope of finding new ways to help ease chronic pain for seniors.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 65 and older who experience chronic pain.

Less likely to help

Patients under the age of 65 or those without chronic pain may not benefit from this research.

What this research studies

This research investigates the reasons behind chronic pain in older adults, focusing on a phenomenon called hyperalgesic priming, which is a change in how pain receptors function due to past injuries or stress. The study will use aged rats to explore how inflammation and other factors contribute to this heightened sensitivity to pain. By measuring inflammatory markers and examining the mechanisms of pain receptor changes, the research aims to identify potential treatments that could alleviate chronic pain in the elderly.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that effectively reduce chronic pain in older adults.

How similar studies have gone: Previous research has shown promising results in understanding pain mechanisms in older populations, suggesting that this approach could yield valuable insights.
