Testing the reliability of a brain blood-flow scan in older adults
Part of Brain & nervous system, Hormones & metabolism, Mental health clinical trials.
This study tests how consistent a special PET scan (called [15O]H2O-PET) is at measuring blood flow in the brain. It is for healthy older adults and involves cognitive testing and possibly light exercise.
Summary written for real people, not researchers, by Clin2.

This study compares how the heart and brain work and how well people think between those with type 2 diabetes and healthy older adults. It aims to understand the effects of diabetes on these functions.
This early-phase study tests a new PET scan tracer that targets a brain chemical transport system involved in dementia. It aims to see if the tracer can safely and clearly show brain changes, which could help future dementia diagnosis or tracking.
This trial studies how tau (a protein linked to Alzheimer’s and related conditions) shows up on a special brain scan called tau PET. It also uses MRI and blood work to understand brain changes and who may be at risk, helping researchers improve future diagnosis.
This Phase 1 study tests a PET scan to measure inflammation-related changes in the brain using a medication called ketoprofen. It may help researchers understand which people with certain brain diseases could benefit from treatments aimed at inflammation.
This study uses brain scans to see how blood flow and sugar transport work in people with both Alzheimer's disease and type 2 diabetes. It may help doctors understand how these conditions interact and find better treatments.
This study uses advanced brain scans to look at brain chemistry in people with type 2 diabetes, narrowed neck arteries, or early memory problems (MCI or early Alzheimer's). It aims to understand how these conditions affect the brain and may help improve future care.
