Changes in serum neurofilament light protein (sNfL) associated with normal aging

According to Dr Michael Khalil, Medical University of Graz, Austria, neurofilament light protein (sNfL) may be useful as a biomarker of age-related sub-clinical brain changes in normal healthy individuals as it can be relatively easily measured in serum. He described how increasing sNfL and increasing variability of levels in older people (>60 years) signifies an acceleration of neurodegeneration.
