How prescription opioids affect thinking and brain health in older adults
Prescription opioids, brain structure, and cognition in older adults with chronic pain
This project follows adults 65 and older with chronic pain to compare brain scans and thinking skills between people who take prescription opioids and those who do not.

What this research studies
If you join, researchers will enroll older adults (65+) with chronic pain and collect medical history, medication records, and tests of thinking and memory over time. They will use brain MRI scans to look at white matter and other structures linked to thinking and compare people who use prescription opioids with similar people who do not. The team will apply statistical methods to try to separate the effects of opioids from the effects of the pain itself and explore biological markers that could explain changes in the brain. Study visits will likely include interviews, cognitive testing, and imaging at Mayo Clinic in Rochester.
Who could benefit from this research
Good fit: Adults aged 65 or older with chronic pain, including people currently prescribed opioids and those using non-opioid treatments, are the ideal candidates.
Not a fit: People under 65, those without chronic pain, or individuals with advanced dementia are unlikely to benefit or be eligible for this project.
Why it matters
Potential benefit: If successful, this work could clarify whether opioids raise the risk of faster thinking decline and help guide safer pain treatment choices for older adults.
How similar studies have performed: Previous observational studies, including work from this team, have linked opioid use to faster cognitive decline and white-matter changes but could not prove causation, so this project builds on prior findings.
