Filaments made of hyperphosphorylated tau protein are encountered in a number of neurodegenerative diseases referred to as “tauopathies”. In the most prevalent tauopathy, Alzheimer's disease, tau pathology progresses in a stereotypical manner with the first lesions appearing in the locus coeruleus and the entorhinal cortex from where they appear to spread to the hippocampus and neocortex. Propagation of tau pathology is also characteristic of argyrophilic grain disease, where the tau lesions appear to spread throughout distinct regions of the limbic system. These findings strongly implicate neuron-to-neuron propagation of tau aggregates. Isoform composition and morphology of tau filaments can differ between tauopathies suggesting the existence of conformationally diverse tau strains. ***Altogether, this points to prion-like mechanisms in the pathogenesis of tauopathies.

***6 Includes 11 cases in which the diagnosis is pending, and 19 inconclusive cases;


***7 Includes 12 (11 from 2014) cases with type determination pending in which the diagnosis of vCJD has been excluded.
