Environmental risk factors for autism: an evidence-based review of systematic reviews and meta-analyses

ConclusionsCompared to genetic studies of ASD, studies of environmental risk factors are in their infancy and have significant methodological limitations. Future studies of ASD risk factors would benefit from a developmental psychopathology approach, prospective design, precise exposure measurement, reliable timing of exposure in relation to critical developmental periods and should  take into account the dynamic interplay between gene and environment by using genetically informed designs.
