Blood Biomarkers & Testing for Alzheimer’s Disease

Recorded at the King’s Conference Centre in Southampton this talk was delivered as part of the Wessex Dementia Research Conference 2025 on 2nd July 2025.

In this session, Professor Jonathan Schott (University College London) provides a clear overview of blood biomarkers in Alzheimer’s disease, exploring their development, current use, and what they might offer for the future of diagnosis and care.

He explains the science behind key biomarkers such as p-tau and NfL, and how these tests could be used in memory clinics, primary care, and even population-level screening. The talk addresses regulatory progress, international comparisons, and the readiness of UK services to adopt this technology. Professor Schott also shares insights from real-world clinical trials and implementation studies, raising important questions about access, equity, and interpretation.

This session offers a comprehensive look at the practical and ethical considerations of using blood tests to detect Alzheimer’s disease, while highlighting the promise and limitations of what’s to come.
