For example, behavioral variant FTD (bvFTD) due to MAPT mutations is, like sporadic bvFTD, characterized by degeneration in the anterior cingulate cortex, insula, striatum, and the amygdala; in addition, bvFTD‐MAPT also is known to more prominently target the mesial temporal lobe (in particular, the hippocampus) – a region that is less likely to exhibit atrophy in sporadic bvFTD.61, 62. Here, MAPT is linked to behavioral variant of frontotemporal dementia.
