These biomarkers include glycated hemoglobin (HbA1c), C-reactive protein (CRP), erythropoietin (EPO), interleukin-6, uric acid, endocan, copeptin, and numerous other molecules involved in the pathogenesis of neurodegenerative diseases, lipid, and vascular metabolic pathways [29,30,31,33,34,35,36,37,38]. This evidence concerns the gene EPO and neurodegenerative disease.
