Advancing Alzheimer’s Disease Detection Through Blood-Based Biomarkers


November 8, 2023



Phosphorylated tau (p-Tau), amyloid-beta (Ab) 42/40, glial fibrillary acidic protein (GFAP), and neurofilament light (NfL) are current key Alzheimer’s disease (AD) blood-based biomarkers. Interpreting results of the four biomarkers simultaneously in a clinical context is challenging due to issues such as tissue sample size, cost, and timing. A decision algorithm could aid in the interpretation, tailored to clinically relevant questions: 1) identify positive amyloid status among preclinical and prodromal AD stages, 2) discriminate AD-dementia from frontotemporal dementia (FTD), and 3) characterize AD-dementia from dementia with Lewy bodies (DLB).

This webinar will discuss the development and validation of such an interpretation tool and demonstrate that the combination of p-Tau 181, GFAP, and NfL in plasma could support decision making in different clinical contexts and serve as a tool to support both detection and differential diagnosis of Alzheimer’s disease.

During this webinar, participants will:

  • Learn about current and upcoming blood-based biomarkers for Alzheimer’s disease and other neuropsychiatric syndromes
  • Gain insight on how multiple biomarkers are needed to sort out the complexities of AD, co-pathologies, and non-AD dementias
  • Hear about the advantages and disadvantages of using these biomarkers for research and clinical correlations
  • Have an opportunity to ask questions during the live broadcast
