Study design
Case-control
Follow Up
Patients were first seen at the time of their initial neurological attack, with additional follow-ups at 3, 6, months, 1 year and from there on annually post their first demyelinating event and at the time of any further demyelinating attacks. Healthy research volunteers completed one study visit and were followed-up 18 months later.
