INTRODUCTION. Multiple sclerosis (MS) it is not considered any more a rare disease in Latin America. Most of the Latin American countries have reported moderate or lower prevalence data. However only very few countries have developed therapeutic guidelines. LACTRIMS prepared this consensus document with specific recommendations for the treatment of the disease. DEVELOPMENT. Experts on treatment and clinical research on MS were invited by LACTRIMS in order to generate a initial document to be discussed in Quito, Ecuador. Several groups were organized in relation of the different clinical variants. These groups were coordinated by experts leaders and prepared a preliminary document that was discussed in Quito during July 8th and 9th, 2011. Finally the final version was submitted to the members and delegates of LACTRIMS in most of the Latin American countries who were able to make modifications and suggest changes to the final manuscript. CONCLUSIONS. Based on the different evidence levels and the AGREE criteria, the clinical variants were reviewed and recommendations were made for the use of drugs and different modifying disease therapeutic agents.
