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. Medial temporal tauopathy may occur independently of Aβ pathology 72 , 73. WebAlzheimer’s disease (AD) is characterized by amyloid plaques composed of the β-amyloid (Aβ) peptide surrounded by swollen presynaptic dystrophic neurites consisting of dysfunctional axons and terminals that accumulate the β-site amyloid precursor protein (APP) cleaving enzyme (BACE1) required for Aβ generation. diamond dynasty lace wigs
