Neurofilament Subunit L Levels in the Cerebrospinal Fluid and Serum of Patients with Amyotrophic Lateral Sclerosis.

Background: There are no reliable biomarkers that could evaluate the disease burden in amyotrophic lateral sclerosis (ALS).

Objectives: The aim of our study is to evaluate the changes in cerebrospinal fluid (CSF) and serum neurofilament subunit L (NF-L) in patients with ALS and to analyze the correlations between the levels of NF-L and clinical parameters.

Method: CSF and serum samples were obtained from 80 ALS patients and 40 controls.

Risk factors of carotid plaque and carotid common artery intima-media thickening in a high-stroke-risk population.

Introduction: To analyze the risk factors of carotid plaque (CP) and carotid common artery intima-media thickening (CCAIMT) and the association between the risk factors and CP numbers and the side of the CCAIMT in a high-stroke-risk population.

Methods: Carotid ultrasonography was conducted in 2025 participants with high stroke risk. Participants were divided into different groups according to the results of the ultrasound.
