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 work publication in Molecular Psychiatry!
In >2,000 BioFINDER participants, we show that CSF p-tau205 tracks Alzheimer’s disease progression and could contribute to biological staging, emerging later than Aβ42/40 and p-tau217 and closer to neocortical tau pathology.
📢 New preprint from BioFINDER, led by @karlssonlinda1!
We trained a deep learning model to generate synthetic tau-PET 3D scans from more accessible data: structural MRI, plasma p-tau217, and age. https://www.medrxiv.org/content/10.64898/2026.05.06.26352540v1
New paper in @GreenJournal! We investigated whether future AD dementia can be predicted in individuals with subjective cognitive decline. We found that plasma p-tau217, cognitive testing, and APOE ε4 status accurately identify those at highest risk. https://www.neurology.org/doi/pdf/10.1212/WNL.0000000000214983

5⃣ In conclusion, our results support the clinical utility of plasma p-tau217 as stand-alone tool for identifying preclinical AD but adding confirmatory CSF/PET would further improve PPVs as needed in many clinical applications.
