Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the most common form of dementia [1] characterized by senile plaque (SP), which is the extracellular deposit of amyloidβ(Aβ)aggregates [2],and neurofibrillary tangle, which is the intracellular accumulation of phosphorylated tau protein [3]. This evidence concerns the gene MAPT and Alzheimer disease.
