The purpose of this study is to obtain long-term clinical data from patients approximately 15 years after their first clinical event, who participated in the former BENEFIT 304747 study and were treated at least once within that study. This study will collect clinical information on the disease course, on disability, relapses, cognitive function over time, quality of life, depression, fatigue, resource use, and employment status. In addition, brain MRI is performed.
