Alzheimer's disease (AD) is characterized by dysfunction and degeneration of neurons in brain regions involved in learning and memory, which is associated with accumulations of aggregated extracellular amyloid β‐peptide (Aβ) and intracellular hyperphosphorylated Tau protein (Mattson, 2004; Crews & Masliah, 2010). Here, MAPT is linked to Alzheimer disease.
