摘要
Background: Patients with logopenic variant of primary progressive aphasia (lvPPA) display neuropathological differences from typical amnestic Alzheimer's disease (AD). Objective: The aim of the study was to compare cerebrospinal fluid (CSF) biomarker levels between patients with lvPPA due to AD (lvPPA-AD), non-logopenic forms of AD (nlAD), and amnestic mild cognitive impairment due to AD (aMCI-AD). Methods: CSF biomarker concentrations were assessed in 124 patients divided into three groups matched for age, level of education, center, and disease duration: lvPPA-AD (n = 30), nlAD (n = 67). and aMCI-AD (n = 27). Results: p-Tau181 levels were higher in the lvPPA-AD group than in the aMCI-AD group (p < 0.05). Total tau levels were higher in the lvPPA-AD group versus those in the nlAD (p < 0.05) and aMCI-AD (p < 0.001) groups. Conclusions: These results suggest a more pronounced involvement of a taupathy in lvPPA-AD compared to aMCI-AD and a more important neuronal death in lvPPA-AD than in nlAD or aMCI-AD.
