Background: Neurofilament light chain (NFL), a potential biomarker of multiple system atrophy (MSA), has been reported in several studies.
Objectives: The objective of this study was to investigate whether plasma NFL levels are correlated with the progression of motor and cognition function in MSA.
Methods: Patients with MSA were part of a prospective cohort study with assessments at baseline and after 1 year. Plasma NFL was quantified using ultrasensitive Simoa technology.
Results: A total of 91 patients with MSA and 60 healthy controls (HCs) were enrolled. NFL levels increased from baseline to 1-year follow-up (P = 0.010). Baseline plasma NFL levels were significantly associated with motor severity and progression in patients with MSA (P < 0.05) but not with cognitive progression (P > 0.05).
Conclusions: Plasma NFL is a reliable biomarker for the disease severity of MSA and monitoring the progression of MSA, but not the progression of cognition. © 2021 International Parkinson and Movement Disorder Society.

Alzheimers Dement (Amst)
January 2025
Introduction: Studies have shown that blood biomarkers can differentiate dementia disorders. However, the diagnosis of dementia still relies primarily on cerebrospinal fluid and imaging modalities. The new disease-modifying treatments call for more widely applicable biomarkers.

Introduction: Novel fluid biomarkers for tracking neurodegeneration specific to Alzheimer's disease (AD) are greatly needed.
Methods: Using two independent well-characterized cohorts (n = 881 in total), we investigated the group differences in plasma N-terminal tau (NT1-tau) fragments across different AD stages and their association with cross-sectional and longitudinal amyloid beta (Aβ) plaques, tau tangles, brain atrophy, and cognitive decline.
Results: Plasma NT1-tau significantly increased in symptomatic AD and displayed positive associations with Aβ PET (positron emission tomography) and tau PET.

Objective: Tofersen, an antisense oligonucleotide, has recently received FDA and EMA approval for treating amyotrophic lateral sclerosis (ALS) in adults with SOD1 gene mutations. This systematic review and meta-analysis synthesized evidence on tofersen's safety and efficacy in patients with SOD1-related ALS.
Methods: A comprehensive search of three databases was conducted from inception through October 2024.

Background: Declining gait performance is seen in aging individuals, due to neural and systemic factors. Plasma biomarkers provide an accessible way to assess evolving brain changes; non-specific neurodegeneration (NfL, GFAP) or evolving Alzheimer's disease (Aβ 42/40 ratio, P-Tau181).
Methods: In a population-based cohort of older adults, we evaluate the hypothesis that plasma biomarkers of neurodegeneration and Alzheimer's Disease pathology are associated with worse gait performance.

Objectives: Loneliness is associated with an elevated risk of dementia. There is mixed evidence from imaging studies on whether loneliness is associated with neuropathology in dementia-free adults. This study tests whether loneliness is associated with plasma neurobiomarkers of amyloid (Aβ42/Aβ40), phosphorylated tau 181 (pTau181), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) and imaging measures of amyloid and tau.
