Multiple sclerosis: Advances in understanding, diagnosing, and treating the underlying disease

Recent advances in our understanding of the diagnosis, imaging, pathology, and clinical monitoring of multiple sclerosis (MS) have significantly increased our ability to successfully treat this often perplexing neurologic disorder. Magnetic resonance imaging (MRI) is now integral to the diagnostic process. Treatment of MS can be considered as three parallel pathways: treatment of relapses, symptom management, and long-term prevention of tissue injury.
