There is some information produced by local scholars and institutions but it needs to be “tied” together. Future epidemiologic research should focus on expanding population-based descriptive data on ASDs, exploring candidate risk factors in large well-designed studies incorporating both genetic and environmental exposure data and addressing possible etiologic heterogeneity in studies that can stratify case groups and consider alternate endophenotypes. It is becoming apparent that: Autism Spectrum Disorder (ASD) is most probably caused by multiple factors interacting in complex ways (i.e. A total of 344 twins (172 pairs; mean age 15.56 ± 5.62 years) enriched for ASD and other neurodevelopmental conditions were examined. d) It is primarily an experimental science.
