Blood protein markers predict MS risk years before diagnosis

For generations, multiple sclerosis has announced itself only after the damage is already done — a diagnosis arriving late to a crisis long underway. Researchers at McGill University's Montreal Neurological Institute-Hospital have now identified eight proteins in the blood that shift measurably years before any symptom appears, offering medicine a rare gift: time. The discovery, validated against pre-diagnostic samples from the UK Biobank, suggests that the body quietly signals its vulnerability long before the nervous system begins to fail — and that learning to read those signals could chang
