Summary
This research article covers the establishing of the Latin American Epidemiological Network of ALS (LAENALS) to perform a comparative analysis of ALS epidemiology between three different Latin American populations (Cuba, Uruguay and Chile). There is evolving evidence of non-uniform distribution of ALS worldwide, with apparently lower incident and prevalent rates outside populations of European origin. LAENALS aims to test the hypothesis that the demographics, phenotype and outcome of ALS are influenced by ancestral origin, and that environmental and occupational risk factors differ across different ethnicities due to subtle differences in gene- environmental interactions
