Neurofilament Light Chain as a Biomarker in Cerebral Small-Vessel Disease

AbstractNeurofilament light chain is part of the neuroaxonal cytoskeleton and upon disease-related neuroaxonal damage, it is released to the extracellular space and, based on modern highly sensitive assays, can also be detected in the peripheral blood. Thus, neurofilament light chain in the blood  is an emerging marker of neurological disease, including age-related conditions, such as neurodegenerative but also neurovascular diseases. Recently, blood neurofilament light chain has been shown to serve as a potentially interesting marker of disease burden and prognostication also in cerebral s mall-vessel disease, a condition that is highly prevalent in elderly subjects. Small-vessel disease is a progressive condition, often related to common vascular risk factors such as arterial hypertension and is an important cause of stroke, vascular cognitive impairment, and dementia. As an age-dep endent condition, small-vessel disease may occur concomitantly with neurodegenerative diseases, with both conditions having a potential impact on clinical status or cognitive performance. The aim of the present article is to give an overview on the current knowledge on neurofilament light chain as a disease or progression marker in small-vessel disease.
