Blood test for Alzheimer's brain changes
Part of Brain & nervous system clinical trials.
This study uses a simple blood test to quickly detect Alzheimer's-related brain changes (amyloid plaques). It may help people with memory concerns avoid a more invasive PET scan and get answers faster.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have memory or thinking problems (mild cognitive impairment, Alzheimer's, or another dementia).
- You have already had a brain amyloid PET scan (using PiB, AV1, or AV45 tracer).
- You have a frozen blood sample from after January 1, 2024, or are willing to give an extra 5 ml of blood.
- You have a brain MRI scan taken within 3 months of your PET scan.
- You do not have severe stroke, liver/kidney disease, drug/alcohol problems, or untreated depression.
- Healthy volunteers without memory problems are also needed (must have a normal PET scan and MRI).
