153: Overviewing the 2025 Alzheimer's Association's Blood-Based Biomarker Guidelines

Welcome to the NeurologyLive® Mind Moments® podcast. Tune in to hear leaders in neurology sound off on topics that impact your clinical practice.Following the 2025 Alzheimer's Association International Conference (AAIC), Rebecca Edelmayer, PhD, outlines the Alzheimer’s Association’s first clinical practice guidelines for using blood-based biomarkers (BBMs) in the diagnostic workup of suspected Alzheimer’s disease within specialized care. She explains the guideline mission, how tests were evaluated for accuracy, and when BBMs should serve as triage versus confirmatory tools relative to CSF and PET. Edelmayer details current scope limits (cognitively impaired patients in specialty settings), cautions against overextending to primary care or unimpaired populations, and previews the education roll-out—executive summaries, micro-learning modules, and shared decision-making resources. She closes with research priorities: stronger peer-reviewed reporting, broader validation across diverse populations and settings, and building an equitable pathway that leverages BBMs to speed accurate diagnosis and treatment access.Looking for more Alzheimer & dementia discussion?
