简要总结
The purpose of this research study is to investigate the effectiveness of MS Disease modifying medications on cognitive fatigue in persons with relapsing remitting multiple sclerosis (RRMS). Cognitive fatigue is the kind of fatigue that occurs after intense mental concentration as after a session of problem solving.
详细描述
The researchers aim is to investigate the effects of disease modifying treatments on cognitive fatigue and on specific brain areas that have been shown to underlie cognitive fatigue in individuals with Multiple Sclerosis (MS). The researchers will investigate the effects on the cognitive fatigue that develops during the performance of a demanding task, and also on how cognitive fatigue changes as a function of duration of treatment.

研究组 & 干预措施
MS Zeposia
Individuals with MS who will begin taking Zeposia as part of standard care.
干预措施: Zeposia (Drug)
结局指标
主要结局
Brain activation (BOLD signal)
时间窗: Measured for change at 3 time points (before, six months and 12 months after intervention)
A change in brain activation as measured with functional magnetic resonance imaging through blood oxygen level dependent signal will be measured in association with cognitive fatigue (as measured by the Visual Analogue scale during performance of the modified Symbol Digit Modality and Modified Fatigue Impact Scale).
次要结局
- Fatigue Onset(Measured for change at 3 time points (before, six months and 12 months after intervention))
