Tauopathies, characterized by abnormal intracellular accumulation of aggregated and/or hyperphosphorylated tau within neurons, is a hallmark of Alzheimer's disease (AD) and a number of other disorders including frontotemporal dementia with parkinsonism-17 (FTDP-17), Pick disease, progressive supranuclear palsy and corticobasal degeneration [5, 21]. Here, MAPT is linked to semantic dementia.
