Blood microRNA test to detect and predict Alzheimer's

MicroRNAs as Diagnostic and Prognostic Biomarker of Alzheimer's Disease

NIH-funded research Boston University Medical Campus · NIH-11297636

This project looks at whether tiny molecules in blood called microRNAs can help spot Alzheimer's early and predict who will get worse among adults with normal memory, mild cognitive problems, or Alzheimer's dementia.

What this research studies

You would be part of work using blood samples to look for microRNAs, small pieces of genetic material that help control brain genes and may change with Alzheimer's. Researchers will sequence microRNAs in plasma from people who are cognitively normal, have mild cognitive impairment, or have Alzheimer's dementia and compare the patterns. The project combines samples from large studies (ADNI, Framingham, and a German dementia study) to increase reliability and search for markers that track disease onset or progression. If patterns are found, they may be tested against clinical records and imaging to see how well the blood signals match brain changes.

Who could benefit from this research

Good fit: Adults (age 21 and older) who are cognitively normal, have mild cognitive impairment, or have Alzheimer's dementia and who can provide blood samples and medical history are the ideal participants.

Not a fit: People under 21, those with non-Alzheimer's neurological diseases, or anyone unwilling to give blood or medical information would likely not benefit from participation.

Why it matters

Potential benefit: If successful, this could lead to a simple blood test that helps detect Alzheimer's earlier and estimate a person's risk of decline.

How similar studies have performed: Previous small studies have reported altered microRNA patterns in Alzheimer's but results have been inconsistent, while blood tests for amyloid and tau have shown clearer promise.
