Examining the link between blood microRNAs and Alzheimer's disease risk and severity

Study on the Relationship Between Peripheral Blood miRNA and Risk and Severity of Alzheimer's Disease

Observational Tongji Hospital · NCT06442852

This study is trying to see if certain tiny molecules in the blood can help us understand the risk and severity of Alzheimer's disease in both patients and healthy volunteers.

What this trial studies

This observational study investigates the relationship between peripheral blood microRNAs and the risk and severity of Alzheimer's Disease (AD). It aims to identify potential biomarkers that could help in understanding the progression of AD and its underlying mechanisms. The study includes both Alzheimer's patients who meet specific diagnostic criteria and healthy volunteers without cognitive impairment. By analyzing blood samples, researchers hope to uncover insights into how microRNAs may influence the disease's development and severity.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with Alzheimer's disease and healthy volunteers without cognitive impairment.

Not a fit: Patients with dementia due to other diseases or those with severe cognitive impairments unrelated to Alzheimer's may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of new biomarkers for early detection and monitoring of Alzheimer's disease.

How similar studies have performed: While the relationship between microRNAs and Alzheimer's disease is being explored, this specific approach is relatively novel and has not been extensively tested in prior studies.
