Notwithstanding progress in understanding of the genetic and neurodevelopmental processes that lead to autism spectrum disorders (ASD), clinical diagnosis is reliant on the developmental and behavioral presentation. Until the 1990s, it was rare for children to receive a diagnosis of autism until the age of 3 or 4 years, and sometimes considerably later (Howlin and Asgharian 1999). This was despite the fact that the DSM and ICD diagnostic systems (American Psychiatric Association [APA] 2000; World Health Organization [WHO] 1993) require that the symptoms be evident in the first 3 years of life, although in the proposed modifications in DSM-5, this requirement has been changed to “Symptoms must be present in early childhood (but may not become fully manifest until social demands exceed limited capacities).” However, nowadays many children are now first identified in the toddler and preschool period (Charman and Baird 2002; Mandell et al. 2005; Manning et al. 2011), although others, in particular those with average or above average language and cognitive abilities, are not diagnosed until school age or older. Several factors have driven this change, including efforts to improve earlier identification with the recognition that earlier-delivered intervention may improve outcomes and prevent “secondary” neurodevelopmental disturbances (Dawson 2008; Mundy et al. 2009): the development of prospective screening instruments to identify possible cases of autism from the first few years of life (Barbaro and Dissanayake 2009); and the use of the genetic “high-risk” research design of prospectively studying younger siblings of children with a diagnosis of ASD from the first year of life (Rogers 2009; Yirmiya and Charman 2010).
