Analysis of selected research cohorts has highlighted an association between plasma neurofilament light (NfL) protein and cross-sectional cognitive impairment as well longitudinal decline. However, the findings have yielded inconsistent results regarding its possible application in clinical practice. Despite potential prognostic significance, role NfL daily practice with unselected patients suffering from remains largely unexplored. This retrospective, monocentric study enrolled 320 Alzheimer's disease ([AD], n = 158), dementia Lewy body ([DLB], 30), frontotemporal ([FTD], 32), non-neurodegenerative diseases ([NND], 59) or subjective decline ([SCD], 41). Plasma levels were measured at baseline on Simoa platform. AD, DLB, FTD also analyzed altogether a 'degenerative conditions' subgroup, whereas SCD NND grouped 'non-degenerative subgroup. We assessed relationship performance, including global cognition six specific domains. A subset 239 had follow-up mini-mental state examinations (MMSE) up to 60 months. Models adjusted age, education level, glomerular filtration rate mass index. In patients, negatively associated (β=-1.28 (-1.81 ; -0.75) P < 0.001), memory (β=-1.48 (-2.38 -0.59), language (β=-1.72(-2.49 -0.95) praxis (β=-2.02 (-2.91 -1.13) 0.001) executive functions (β=-0.81, 0.001). Across diagnosis, all but specifically AD (respectively β=-0.71(-1.21 -0.211), 0.005 β=-1.29 (-2.17 -0.42), 0.004), attention LBD (β=-0.81(-1.16 -0.002), 0.03). Linear mixed-effects models showed that predicted MMSE population (βPlasmaNfLxTime=-0.15 (-0.26 -0.04), 0.006), neurodegenerative condition subgroup (βPlasmaNfLxTime=-0.21 (-0.37 − 0.06), 0.007), not our cohort, was faster dementia, which corroborates data obtained cohorts. Yet, predictive accelerated individuals without neurodegeneration, suggesting use neurodegeneration-specific biomarker.
