Webdystrophic neurites (tau-containing degenerated axons and dendrites surrounding Aβ plaques). Although these structures can be seen in some brainstem nuclei in young adults 69 , tauopathy in the medial temporal lobe is the initial site relevant to cognition 70 , 71.

WebFeb 29, 2000 · The appearance of these dystrophic neurites was very similar to those seen surrounding thioflavine-S-positive deposits in AD brain by using the same method (Fig. 1). These findings support the possibility that the process of structural changes in which Aβ is converted from a “soluble/diffuse” form to a “fibrillar” form results in the ...
