The Swedish BioFINDER Study
The BioFINDER studies are independent and non-overlapping studies that have been initiated with the overarching aims to discover key mechanisms in Alzheimer’s disease, Parkinson’s disease and other neurodegenerative disorders. These studies are designed to develop early and accurate diagnostic tests, identify novel treatment targets and help to understand the links between different pathologies and clinical symptoms.

New paper out in EMBO Mol Med! We use machine learning to predict Aβ-PET burden from fluid biomarkers
Findings:
-Performance R² = 0.79
-CSF Aβ42/Aβ40 most predictive of Aβ plaque presence
-Plasma p-tau217 best for tracking increasing amyloid plaque burden
Prediction of continuous amyloid positron emission tomography with fluid measures of phosphorylated...

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.
The study was led by @NiklasMattsson4, @karlssonlinda1, and Weizhong Tang. Thank you to all co-authors: Kaj Blennow, Henrik Zetterberg, @RandallBateman3, @SuzanneESchind1, Nicolas Barthelemy, @SebastianPalmqv, @EStomrud, Shorena Janelidze, and @OskarHansson9.

Systematic Review & Meta-analysis of ALS Fluid Biomarkers
🧵Key findings:
• NfL leads for both diagnosis (AUC 0.81–0.92) & prognosis (HR 2.8–4.3)
• CSF chitinases, p-tau/t-tau: moderate values
• Marked heterogeneity

💡 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.
