Socioeconomic status and access to multiple sclerosis treatment in Mexico

•We evaluated the association between SES and DMT access from a national referral center in Mexico.•A significant influence of SES was found on the percentage of patients with higher levels of disability (EDSS >6), the proportion of patients not receiving any DMT and a higher proportion of secondary progressive MS in lower SES levels.•We found that lower educational levels had a significance and inverse association with EDSS on first visit, symptomatic onset to diagnosis and a higher disability status.
