Elizabeth Usher Memorial Lecture: Rethinking the clinical pathway for autism spectrum disorder and challenging the status quo

The aim of the paper is to outline the future of early identification and intervention of ASD and the research goals to be addressed to achieve this vision.

Unpacking the complex nature of the autism epidemic

This paper discusses changes in diagnostic criteria, decreasing age at diagnosis, improved case ascertainment, diagnostic substitution, and social influences.

Adult psychosocial outcomes of children with specific language impairment, pragmatic language impairment and autism

Evidence that some children also develop autistic symptomatology over time has raised suggestions that developmental language disorder...

Cerebral dominance for language function in adults with specific language impairment or autism

A link between developmental language disorders and atypical cerebral lateralization has been postulated since the 1920s, but evidence has been indirect and...

Do children with autism 'switch off' to speech sounds? An investigation using event-related potentials

Autism is a disorder characterized by a core impairment in social behaviour. A prominent component of this social deficit is poor orienting to speech.

Autism and diagnostic substitution: Evidence from a study of adults with a history of developmental language disorder

Rates of diagnosis of autism have risen since 1980, raising the question of whether some children who previously had other diagnoses are now being diagnosed...

Evidence against poor semantic encoding in individuals with autism

This article tests the hypothesis that individuals with autism poorly encode verbal information to the semantic level of processing, instead paying greater...

Interactions between the lipidome and genetic and environmental factors in autism

Autism omics research has historically been reductionist and diagnosis centric, with little attention paid to common co-occurring conditions (for example, sleep and feeding disorders) and the complex interplay between molecular profiles and neurodevelopment, genetics, environmental factors and health. Here we explored the plasma lipidome in 765 children (485 diagnosed with autism spectrum disorder (ASD)) within the Australian Autism Biobank.

Assessing Restricted and Repetitive Behaviours in Online-Sampled Autistic and Non-autistic Individuals: Factor Structure of the Repetitive Behaviours Questionnaire for Adults (RBQ-2A)

The Repetitive Behaviours Questionnaire for Adults (RBQ-2A) measures two factors of restricted and repetitive behaviours (RRBs) associated with autism. However, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provides four criteria for RRBs: repetitive motor behaviours, insistence on sameness, restricted interests, and interest in sensory aspects of the environment (or atypical sensitivity).

Estimated Therapy Costs and Downstream Cost Consequences of iBASIS-Video Interaction to Promote Positive Parenting Intervention vs Usual Care Among Children Displaying Early Behavioral Signs of Autism in Australia

The growing global prevalence of autism spectrum disorder is associated with increasing costs for support services. Ascertaining the effects of a successful preemptive intervention for infants showing early behavioral signs of autism on human services budgets is highly policy relevant.
