Validation of blood biomarkers for Alzheimer's disease

Clinical Validation of the Use of Blood Biomarkers for the Diagnosis and Monitoring of Alzheimer's Disease

NA · University Hospital, Montpellier · NCT05427448

This study is testing whether certain blood tests can help doctors diagnose Alzheimer's disease more accurately by comparing them to traditional tests done on spinal fluid.

What this trial studies

This study aims to evaluate the diagnostic performance of blood biomarkers for Alzheimer's disease (AD) through a prospective clinical trial. It focuses on measuring amyloid peptides, tau proteins, and neurofilaments in blood samples from patients consulting at memory clinics. The study will compare these blood biomarkers with cerebrospinal fluid (CSF) analysis to assess their effectiveness in diagnosing AD and related conditions. The goal is to improve the stratification of patients and enhance diagnostic accuracy in clinical practice.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are consulting at memory clinics and have undergone CSF AD biomarker testing.

Not a fit: Patients who refuse lumbar puncture or are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a less invasive and more accessible method for diagnosing Alzheimer's disease.

How similar studies have performed: Other studies have shown promise in using blood biomarkers for Alzheimer's diagnosis, but this approach is still being validated in a prospective setting.
