WebAug 5, 2024 · CSF p-tau, t-tau and neurogranin are widely accepted biomarkers of tau protein pathophysiology, neurodegeneration, and synaptic dysfunction, respectively. These associations between AD biomarkers and ePVS survived after correcting for relevant demographic and cardiovascular risk factors, as well as CSF Aβ40 levels. WebNeurodegenerative tauopathies are marked by their common pathologic feature of aggregates formed of hyperphosphorylated tau protein, which are associated with synapse and neuronal loss. Changes in tau conformation result in both loss of normal function and gain of fibrillogenicity that leads to aggregation. Here, we discuss the pathophysiology of …
