Autism spectrum disorder is a severe developmental disability of genetic and neurological etiology that cannot yet be diagnosed in the first months of life. Different research methods have been used to identify behavioral or cognitive markers that permit early identification of the disorder. Some of the procedures involve parental retrospective reports, analysis of home videos or prospective studies of siblings of children with autism. Research shows differences as from twelve months of age, but not earlier, in behaviors such as joint attention, response to name, delays in verbal and non-verbal communication, atypical exploring of objects, motor delay, certain repetitive behaviors, differences in temperament and reduced imitation. However, conflicting results are still apparent among different studies even in these behaviors. In addition, at this moment no single marker consistently predicts diagnoses of autism at a later age.
