Translation requires biomarkers before treatment trials: CSF/plasma 4-HNE, F2-isoprostanes, oxidized PE species, GPX4 activity, and iron MRI should stratify patients. Deferiprone-like strategies need careful anemia and mitochondrial safety monitoring.

["Motor neurons are credible candidates for ferroptotic vulnerability because high metabolic demand, long axons, and PUFA-rich membranes raise lipid-peroxidation burden.", "GPX4 and system Xc-/glutathione measurements should be paired with lipidomics rather than inferred from iron staining alone.", "Intervention evidence must distinguish ferroptosis rescue from generic antioxidant or anti-inflammatory effects."]
