At first, neuronal and glial inclusions of hyperphosphorylated tau protein were identified in FTLD-tau, which represent nearly 30–40% of FTLD cases, and are found in patients carrying MAPT gene mutations, as well as in Pick’s disease, PSP, and corticobasal degeneration (CBD) (Josephs et al., 2006). Here, MAPT is linked to red-green color blindness.
