Abstract: 【Abstract】Currently, blood purification has been the first-line therapy for many immunEmediated neurological disorders. Plasma exchange (PE) and immunoadsorption (IA) are the two blood purification modalities commonly used in the treatment of immunEmediated neurological disorders. PE and IA significantly improve neurological function of the patients with immunEmediated neurological disorders via removing various kinds of pathogenic factors from circulating blood. This paper reviews the research progresses in the treatment of immunEmediated nervous system diseases by using blood purification.
