More than twenty years before the first symptom, something was already showing up in people's blood.
A study published in Brain this month has put the sequence in order. Swedish researchers went back to blood frozen in national biobanks years before anyone knew who would go on to develop MS. Nine hundred and eighty one people who did, matched against twelve hundred and seventy eight who didn't.
Antibodies against the Epstein Barr virus in its active phase, more than twenty years out. The latent marker at fifteen. Antibodies against one of the body's own proteins at nine. A marker of nerve damage at seven.
Two things the headlines will drop. These are group averages, not a clock you can put yourself on, and there's no test here to ask for. And the study can't prove the virus caused any of it.
