Notably, tau pathology is not only presented in AD but also associated with many other tau pathologies, such as chronic traumatic encephalopathy (CTE), a subclass of frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17tau); Pick’s disease (PiD); progressive supranuclear palsy (PSP); corticobasal degeneration (CBD); and argyrophilic grain disease (AGD) [94]. The gene discussed is MAPT; the disease is Alzheimer disease.
