Neurofilament Light: A Biomarker of Nervous System Damage
The Promise of Neurofilament Light (NfL) as a Biomarker Neurofilament Light (NfL) is a structural component of axons that provides stability. When neurons are damaged or destroyed, NfL is released into the cerebrospinal fluid (CSF) and bloodstream. The more severe the damage, the higher the levels of NfL.(1) Elevated NfL
