Using diffusion tensor imaging to detect cortical changes in fronto-temporal dementia subtypes.

ABSTRACT: Fronto-temporal dementia (FTD) is a common type of presenile dementia, characterized by a heterogeneous clinical presentation that includes three main subtypes: behavioural-variant FTD, non-fluent/agrammatic variant primary progressive aphasia and semantic variant PPA. To better understand the FTD subtypes and develop more specific treatments, correct diagnosis is essential. This study aimed to test the discrimination power of a novel set of cortical Diffusion Tensor Imaging measures (DTI), on FTD subtypes. A total of 96 subjects with FTD and 84 healthy subjects (HS) were included in the study. A "selection cohort" was used to determine the set of features (measurements) and to use them to select the "best" machine learning classifier from a range of seven main models. The selected classif
