We’d love to hear your thoughts and feedback!

Main takeaway:
CSF Ab42/Ab40 and plasma p-tau217 showed distinct contributions when predicting Aβ-PET, improving our understanding of disease progression and guiding how biomarkers can be applied in clinical and research settings.

💡 Takeaway:
• NfL is robust but not sufficient alone in low-prevalence settings.
• Diagnostic and prognostic frameworks should move toward standardized multimodal models integrating fluid #biomarkers with established predictors.

🎯The use of plasma p-tau217 will reduce resource demands and burdensome procedures accelerating the development and implementation of early AD therapeutics.

7/🧵 These results suggest that hemispheric difference in Aβ deposition, rather than reduction in connectivity, is associated with asymmetric tau accumulation, highlighting regional vulnerability as a crucial factor in determining the distribution of AD pathology.

4⃣In summary, we have developed a biomarker-based staging model using plasma tau biomarkers and validated in TRIAD. We believe these findings will enhance the application of blood tau biomarkers, improving patient management in both clinical trials and routine clinical practice.

6/🧵Taken together, we present an accurate two-step approach for predicting LBP in the brain using a smell test followed by CSF SAA testing in smell-test positive individuals. This could minimize costs, reduce patient burden, and improve the known underdiagnosis of DLB and PD.

7⃣This suggests that region-specific atrophy functions as one pathway of tau-induced cognitive subdomain impairments. Yet, large portions of variance remains unexplained, highlighting the need for investigating other mechanistic links.🔬

8⃣A huge thank you to all authors as well as the #ADNI study participants who made this work possible. Your contributions are vital for advancing our understanding of the disease and contribute to #ENDALZ.
