The purpose of this study was to evaluate the extent and localization of white matter (WM) damages in individuals with primary progressive aphasia (PPA) by using Tract-Based Spatial Statistics (TBSS), extending the findings of previous voxel and tract-based analyses of multi-subject Diffusion Tensor Imaging (DTI) data. WM integrity was studied by comparing three groups of patients (three major subtypes of PPA: non-fluent/agrammatic (PNFA), semantic variant (SD) and logopenic variant (LPA)) with a group of age-matched healthy controls.
