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.

Abstract INTRODUCTION People with neurodegenerative disorders (ND) frequently face diagnostic delay and misdiagnosis. We investigated blood cerebrospinal fluid (CSF) neurofilament light chain (NfL) to distinguish ND from primary psychiatric (PPD), a common challenge in clinical settings. METHODS Plasma CSF NfL levels were measured compared between groups, adjusting for age, sex, weight. RESULTS A total of 337 participants included: 136 ND, 77 PPD, 124 Controls. was 2.5‐fold elevated PPD had strong performance (area under the curve, [AUC]: 0.86, 81%/85% specificity/sensitivity) that comparable (2‐fold elevated, AUC: 0.89, 95%/71% specificity/sensitivity). Diagnostic especially younger people (40– < 60 years). Additional findings cutoffs optimized sensitivity specificity, issues important future translation. CONCLUSIONS This study adds evidence simple blood‐based biomarker assist as screening test neurodegeneration distinction Highlights significantly higher versus PPD. showed performance, NfL, people, where challenges are greater.

Background: Predicting which patients with prodromal AD (pAD) will imminently convert to dementia may be paramount in a memory clinical setting, especially potential disease-modifying therapies on the horizon. Objective: To explore practical tool for this prediction, combining cognitive tests and cerebrospinal fluid (CSF) biomarkers. Methods: We designed longitudinal prospective, observational, multicenter study, enrolling pAD. Inclusion criteria comprised complaints, Mini-Mental State Examination (MMSE) score of≥22, impairment as indicated by Free Cued Selective Reminding Test Immediate Recall (FCSRT + IR) and/or TMA-93, Clinical Dementia Rating-Global Score (CDR-GS) of 0.5, positive CSF Aβ42/Aβ40 ratio (<0.095, Euroimmun). The primary outcome was conversion (CDR-GS≥1) within first year follow-up, referred “short-term conversion”. A multiple regression logistic model adopted design “Predict Short-Term Conversion” (PSTC) score. Results: Between 2020 2022, 83 were recruited. median age 74, 49.4% being women. Twenty-five (30.1%) classified short-term converters.
