      abstract     = {This study tested the hypothesis that patients with primary
                      progressive aphasia (PPA) who do not meet the proposed
                      criteria for any of the recognized subtypes would have the
                      atrophy pattern reported in the past for logopenic variant
                      PPA (lvPPA), in turn suggesting that the PPA of likely
                      Alzheimer disease origin is more variable than that captured
                      in the current lvPPA diagnostic recommendations.MRI gray
                      matter volumes from 14 patients with mixed PPA who failed to
                      meet the diagnostic recommendations for any recognized
                      variant were compared with those of 25 matched control
                      participants via voxel-based morphometry.The mixed PPA group
                      had left temporoparietal atrophy with a pattern identical to
                      that in previously reported lvPPA cohorts.Patients with PPA
                      who did not meet the criteria for any recognized PPA variant
                      at their initial assessment had the group-level atrophy
                      pattern previously reported as the hallmark of lvPPA. We
                      suggest that the specific language features proposed for
                      lvPPA are too narrow to characterize the language
                      impairments arising from likely Alzheimer pathology.},
