Autism Spectrum Disorder (ASD) is a construct used to describe individuals with a specific combination of impairments in social communication and repetitive behaviours, highly restricted interests and/or sensory behaviours beginning early in life. The worldwide prevalence of autism is just under 1%, but estimates are higher in high-resource countries. Although gross brain pathology is not characteristic of autism, subtle anatomical and functional differences have been observed in postmortem, neuroimaging and electrophysiological studies. Initially it was hoped that accurate measurement of behavioural phenotypes would lead to specific genetic subtypes, but genetic findings have mainly applied to heterogeneous groups that are not specific to autism. Psychosocial interventions in children can improve specific behaviours, such as joint attention, language and social engagement that may affect further development and could reduce symptom severity. However, further research is necessary to identify the long-term needs and treatments and the mechanisms behind them that could result in improved independence and quality of life over time. Families are often the major source of support for people with AUTISM throughout much of life and need to be considered, along with the perspectives of autistic persons, in both research and practice. [H1] Introduction Autism spectrum disorder (ASD) is a common, highly heritable and heterogeneous neurodevelopmental disorder that has underlying cognitive features and commonly co-occurs with other conditions. The Autism spectrum disorder-or autism-is a neurodevelopmental disorder that typically manifests in young children. This Primer by Lord and colleagues reviews the epidemiology, mechanisms, clinical detection and treatment of autism.

WHAT'S KNOWN ON THIS SUBJECT: Previous research has identified low rates of employment and postsecondary education for youth with autism, but generalizability has been limited by small samples. WHAT THIS STUDY ADDS:Using national data, the authors of this study found that youth with autism are at high risk for no postsecondary education or employment, especially in the first 2 years after high school. Findings highlight the need for improved transition planning. abstract OBJECTIVES: We examined the prevalence and correlates of postsecondary education and employment among youth with an autism spectrum disorder (ASD).METHODS: Data were from a nationally representative survey of parents, guardians, and young adults with an ASD. Participation in postsecondary employment, college, or vocational education and lack of participation in any of these activities were examined. Rates were compared with those of youth in 3 other eligibility categories: speech/ language impairment, learning disability, and mental retardation. Logistic regression was used to examine correlates of each outcome. RESULTS:For youth with an ASD, 34.7% had attended college and 55.1% had held paid employment during the first 6 years after high school. More than 50% of youth who had left high school in the past 2 years had no participation in employment or education. Youth with an ASD had the lowest rates of participation in employment and the highest rates of no participation compared with youth in other disability categories. Higher income and higher functional ability were associated with higher adjusted odds of participation in postsecondary employment and education. CONCLUSIONS:Youth with an ASD have poor postsecondary employment and education outcomes, especially in the first 2 years after high school. Those from lower-income families and those with greater functional impairments are at heightened risk for poor outcomes. Further research is needed to understand how transition planning before high school exit can facilitate a better connection to productive postsecondary activities.

This report describes the post-high school educational and occupational activities for 66 young adults with autism spectrum disorders who had recently exited the secondary school system. Analyses indicated low rates of employment in the community, with the majority of young adults (56%) spending time in sheltered workshops or day activity centers. Young adults with ASD without an intellectual disability were three times more likely to have no daytime activities compared to adults with ASD who had an intellectual disability. Differences in behavioral functioning were observed by employment/day activity group. Our findings suggest that the current service system may be inadequate to accommodate the needs of youths with ASD who do not have intellectual disabilities during the transition to adulthood.
