Relapsing Remitting Multiple Sclerosis (RRMS) is defined by repeated attacks of inflammation and flare-ups in patients already diagnosed with multiple sclerosis. The myelin sheath covering neurons in the CNS is attacked by auto-reactive immune cells, which induce massive inflammatory pathways, leading to a varied range of symptoms in patients. However, every attack is targeted at a different spot and symptoms vary in each individual. In MRI scans, it is often seen that patients with RRMS have a greater number of plaques or scars, which are patches of inflammatory cells in a cluster.
