    ✓ Peer-reviewed alzhub usefulness score 64 out of 100. Neurology 2022-03-21 Brain scans and imaging

    Aβ-positive individuals can remain tau-negative for at least 5 years.

  3. Plasma levels of phosphorylated tau 181 are associated with cerebral metabolic dysfunction in cognitively impaired and amyloid-positive individuals

    ✓ Peer-reviewed alzhub usefulness score 66 out of 100. Brain communications 2021-04-15 Biomarkers
