Investigating a new blood biomarker for Alzheimer's disease

Plasma brain-derived tau: a novel Alzheimer’s disease-type neurodegeneration biomarker with potential to complete the AT(N) scheme in blood

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11086130

This study is looking at a new blood test called brain-derived tau (BD-tau) to see if it can help doctors better diagnose Alzheimer's disease and track how it affects people over time, especially across different backgrounds.

What this research studies

This research focuses on developing and validating a novel biomarker called brain-derived tau (BD-tau) that can be measured in blood to improve the diagnosis of Alzheimer's disease (AD). The study will analyze data from diverse patient cohorts to compare BD-tau with existing biomarkers, such as neurofilament light (NfL) and total-tau (t-tau), to determine its effectiveness in diagnosing AD and tracking cognitive decline. By leveraging existing clinical and post-mortem evaluations, the research aims to enhance the accuracy of AD diagnosis and understand its implications across different racial and ethnic groups.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals diagnosed with Alzheimer's disease or those experiencing cognitive decline.

Not a fit: Patients with other forms of dementia or neurological conditions unrelated to Alzheimer's may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more accurate and accessible blood tests for diagnosing Alzheimer's disease.

How similar studies have performed: Previous research has shown promise in using blood biomarkers for neurodegenerative diseases, but the specific approach of using BD-tau is novel.
