Presymptomatic Amyotrophic Lateral Sclerosis: From Early Biomarker Detection to Phenoconversion Prediction
Amyotrophic lateral sclerosis (ALS) usually enters diagnostic pathways after motor symptoms emerge, by which time neural injury has been ongoing. Long-term hereditary ALS cohorts show that some pathogenic-variant carriers may show elevated neurofilament light chain (NfL), mild motor impairment (MMI), electromyographic...
