WebMany hypotheses have been raised regarding the pathophysiology of Alzheimer's disease (AD). Because amyloid beta peptide (Ab) deposition in senile plaques appears as a late, nonspecific event, recent evidence points to tau phosphorylation and aggregation as the final common pathway in this multifactorial disease. WebOct 19, 2024 · 2.1. Historical evolution. The amyloid hypothesis has dominated the AD field and is based largely on the persuasive genetics of autosomal dominant AD and corroborative data from genetic mouse models, positing that Aβ accumulation initiates and drives the tau pathology, which disables and ultimately kills affected neurons. 1 This …
