title: Posterior cingulate neurometabolite profiles and clinical phenotype in frontotemporal dementia.
abstract: Proton magnetic resonance spectroscopy was used to compare metabolite levels from a posterior cingulate voxel in a group of patients with 2 syndromic subtypes of frontotemporal dementia (n=10) and an age and education-matched group with Alzheimer disease (n=10). Overall, frontotemporal dementia was indistinguishable from Alzheimer disease, though differences in N-acetylaspartate emerged between patients with the SD and progressive nonfluent aphasia subtypes, attributable to 2 atypical results among the latter. Such values may index cases with atrophy in posterior cortical regions presenting with progressive nonfluent aphasia.
