Alzheimer's imaging and biomarker initiative (ADNI4)
Alzheimer's Disease Neuroimaging Initiative (ADNI4)
This project collects brain scans, blood and spinal fluid samples and health information from people with and without memory problems to improve tests that spot Alzheimer's earlier and more accurately.

What this research studies
If you join ADNI4 you would provide medical history, cognitive testing, brain imaging, and blood and sometimes spinal fluid samples, and some participants are followed over time. The project combines these data to refine blood, imaging, and other biomarkers that can predict who will develop dementia. ADNI4 places special emphasis on adding more participants from underrepresented racial and ethnic groups so the results apply to more people. The program maintains and widely shares its data and samples so other researchers and clinical trials can build on the findings.
Who could benefit from this research
Good fit: Ideal candidates include adults across the memory spectrum — people with normal cognition, mild cognitive impairment, or early Alzheimer dementia — with a priority for enrollment of underrepresented racial and ethnic groups.
Not a fit: People seeking an immediate treatment benefit should not expect direct clinical improvement because ADNI4 is an observational biomarker and data-sharing effort rather than a treatment trial.
Why it matters
Potential benefit: If successful, this work could enable earlier and more reliable detection of Alzheimer's and help design better clinical trials and treatments for patients.
How similar studies have performed: Previous ADNI phases have produced thousands of publications and guided clinical trial design, including work used in aducanumab trials, so the approach is well-established and influential.
