Abbreviations: bvFTD: behavioural variant frontotemporal dementia; FTLD-CDR = frontotemporal lobar degeneration Clinical Dementia Rating; MMSE: Mini Mental State Examination.
*According to International Behavioral Variant FTD Consortium Criteria [24]. + 6 patients fulfill definite bvFTD criteria according to neuropathological examination, 2 according to genetic examination, and one according to both. Demographic factors and clinical characteristics were compared using Chi-square (x2) and Mann-Whitney U tests [Sex: x2 = 0, p > 0.9; Age: U = 155, p = 0.052; MMSE: U = 13.5, p < 0.001].
