A study in Nature Medicine found that a single blood test model using plasma %p-tau217 can estimate when Alzheimer’s symptoms are likely to begin. In 603 patients, the model linked biomarker positivity with symptom onset, with a median error of 3.0 to 3.7 years.

New research reveals significant advances in blood-based biomarkers for Alzheimer's disease, including a pTau 217 assay showing 93% agreement with amyloid PET imaging and identification of interferon gamma as a diagnostic signal linked to genetic risk. These developments address challenges in early diagnosis and monitoring while requiring substantially less plasma than previous tests.

Recent studies demonstrate that blood-based biomarkers combined with AI can predict dementia risk 25 years early in women, identify liver cancer-prone environments with 93% accuracy, and classify prediabetes risk groups with 90% accuracy.
Feb 20, 2026
Researchers at Washington University School of Medicine developed a blood test-based method to predict when Alzheimer's symptoms will begin, with accuracy within three to four years, using plasma p-tau217 protein levels.
