Among these are the tauopathies, which exhibit accumulation of tau protein [2] and include Alzheimer’s disease (AD), progressive supranuclear palsy, Pick’s disease, corticobasal degeneration, and frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17) [3–6]. This evidence concerns the gene MAPT and early-onset autosomal dominant Alzheimer disease.
