Background:Astrocytes play an essential role in neuroinflammation and are involved in the pathogenesis of neurodenegerative *** of glial fibrillary acidic protein(GFAP),an astrocytic damage marker,may help advance our understanding of different neurodegenerative *** this study,we investigated the diagnostic performance of plasma GFAP(pGFAP),plasma neurofilament light chain(pNfL)and their combination for frontotemporal dementia(FTD)and Alzheimer's disease(AD)and their clinical utility in predicting disease ***:pGFAP and pNfL concentrations were measured in 72 FTD,56 AD and 83 cognitively normal(CN)participants using the Single Molecule Array *** the 211 participants,199 underwent cerebrospinal(CSF)analysis and 122 had magnetic resonance *** compared cross-sectional biomarker levels between groups,studied their diagnostic performance and assessed correlation between CSF biomarkers,cognitive performance and cortical *** prognostic performance was investigated,analyzing cognitive decline through group comparisons by ***:Unlike pNfL,which was increased similarly in both clinical groups,pGFAP was increased in FTD but lower than in AD(all P<0.01).Combination of both plasma markers improved the diagnostic performance to discriminate FTD from AD(area under the curve[AUC]:combination 0.78;pGFAP 0.7;pNfL 0.61,all P<0.05).In FTD,pGFAP correlated with cognition,CSF and plasma NfL,and cortical thickness(all P<0.05).The higher tertile of pGFAP was associated with greater change in MMSE score and poor cognitive outcome during follow-up both in FTD(1.40 points annually,hazard ratio[HR]3.82,P<0.005)and in AD(1.20 points annually,HR 2.26,P<0.005).Conclusions:pGFAP and pNfL levels differ in FTD and AD;and their combination is useful for distinguishing between the two *** could also be used to track disease severity and predict greater cognitive decline during follow-up in patients with FTD.
