This special issue of the ARCHIVES on autism spectrum disorders (ASDs) highlights new approaches to the early identification and treatment of autism, and the associated financial and emotional costs to families and society. While current approaches to early identification involve behavioral screenings, several of which are described in this issue, a longer-term goal is to develop biomarkers that can lower the age at which young infants at risk for autism can be recognized. Although scientists are searching for biomarkers that can identify infants at risk for autism, no reliable biomarkers have yet been identified. Genetic research will be important for identifying such biomarkers.
