As expected, tau haplotypes (H1H2 and H2H2) showed impairments in cognition (general cognitive state, visual-constructional skills, executive functioning, and ToM skills) and more severe chronic neuropsychiatric symptoms (total scores, disinhibition, apathy, and disorganized behavior) compared to S-FTD (GR3) [36, 77]. This evidence concerns the gene MAPT and frontotemporal dementia.
