In fact, the extent of neuronal tau in FTD + MND, in line with that seen in FTD, was not greater, but in fact less, than that seen in MND alone, and a glial cell tau pathology specifically detected by pThr217 immunostaining in MND [36] was not seen in either FTD + MND or FTD alone. Here, MAPT is linked to mild neurocognitive disorder.
