| Povzetek: | The complexity of neurodegenerative disorders necessitates an integrative approach that incorporates morphological, functional, and molecular biomarkers. The advent of highly sensitive single-molecule array (Simoa®) assays has significantly enhanced the accuracy of blood-based biomarker quantification, including glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL), and phosphorylated tau181 (p-tau181). This study evaluates the diagnostic utility of these biomarkers in neurodegenerative diseases. We analyzed data from 279 individuals from the PADUA-CESNE cohort: 120 with Parkinson's disease (PD), 88 with Alzheimer's disease (AD), 16 with frontotemporal dementia (FTD), 11 with multiple system atrophy (MSA), 14 with progressive supranuclear palsy (PSP), and 30 cognitively unimpaired controls. NfL levels were significantly lower in PD and AD compared to atypical parkinsonisms and FTD, effectively distinguishing MSA and PSP from controls. NfL also negatively correlated with Montreal Cognitive Assessment (MoCA) scores in AD and PD, indicating its association with cognitive decline. Elevated GFAP levels were observed in both PD and AD and inversely correlated with global cognition. Combining GFAP and p-tau181 improved AD differentiation from PD and other parkinsonian disorders, while the integration of all three biomarkers facilitated the distinction between AD and FTD. Notably, lower NfL levels (<20 ng/L) in conjunction with elevated p-tau181 were indicative of AD, whereas NfL levels below 40 ng/L were suggestive of PD. In conclusion, NfL serves as a sensitive indicator of neurodegeneration, albeit with limited specificity. However, by establishing biomarker concentration thresholds and integrating complementary biomarkers, blood-based assays may enhance the differential diagnosis of neurodegenerative diseases, providing valuable clinical insights. |
