Alzheimer's disease (AD) is the most common form of dementia and is marked with cognitive impairment, cell loss, and reduction of life expectancy. Pathologically, senile plaque, beta-amyloid (Aβ) aggregates, and neurofibrillary tangle, tau aggregates, are the hallmark of the disease. Although genetics studies provide a causative link between the disease and Aβ accumulation, the interaction between Aβ and tau and its contribution to the
