A review of the aetiology of multiple sclerosis: an ecological approach

Abstract

Multiple sclerosis (MS) is a disease of unknown aetiology characterized by myelin destruction. Approaches to the aetiology of the condition have noted its differential geographic and demographic distribution; a tentative and inconsistent link with infectious agents; a genetic susceptibility; and a tendency to track with dietary lipids. This review proposes a multidisciplinary approach to the aetiology of MS, emphasizing the interlocking and interdependent nature of current aetiological arguments. We suggest that the most profitable interpretation of current empirical data on the aetiology of MS can be accomplished through this kind of analysis.
