Commentary: A spectrum for all? A response to Green et al. (2023), neurodiversity, autism and health careThe broadening of the clinical definition of autism over time-the so-called, autism spectrum-has run in parallel with the growth of a neurodiversity movement that has reframed the concept of autism entirely. Without a coherent and evidence-based framework through which both of these advances can be situated, the field is at risk of losing definition altogether.

Duration of general anaesthetic exposure in early childhood and long-term language and cognitive abilityAnaesthetic dose causing toxicity in animals has been evaluated, but the relationship between duration of VA exposure and development in children remains vague.

Hypermasculinised facial morphology in boys and girls with Autism Spectrum Disorder and its association with symptomatologyThis is the first study demonstrating facial hypermasculinisation in ASD and its relationship to social-communication difficulties in prepubescent children

Occurrence of psychosis and bipolar disorder in adults with autism: A systematic review and meta-analysisEvidence suggests that individuals with autism spectrum disorder have increased rates of co-occurring psychosis and/or bipolar disorder. Considering the peak age of onset for psychosis and bipolar disorder occurs in adulthood, we investigated the co-occurrence of these disorders in adults with autism.

The Utility of Natural Language Samples for Assessing Communication and Language in Infants Referred with Early Signs of AutismNatural Language Sampling (NLS) offers clear potential for communication and language assessment, where other data might be difficult to interpret. We leveraged existing primary data for 18-month-olds showing early signs of autism, to examine the reliability and concurrent construct validity of NLS-derived measures coded from video-of child language, parent linguistic input, and dyadic balance of communicative interaction-against standardised assessment scores. Using Systematic Analysis of Language Transcripts (SALT) software and coding conventions, masked coders achieved good-to-excellent inter-rater agreement across all measures.

Investigating associations between birth order and autism diagnostic phenotypesBirth order effects have been linked to variability in intelligence, educational attainment and sexual orientation. First- and later-born children have been linked to an increased likelihood of an Autism Spectrum Disorder (ASD) diagnosis, with a smaller body of evidence implicating decreases in cognitive functioning with increased birth order.

Performance of the Autism Observation Scale for Infants with community-ascertained infants showing early signs of autismWe investigated whether a commonly used research assessment - the Autism Observation Scale for Infants (AOSI) - accurately measures autism behaviours among infants showing early signs of autism identified within the community. The AOSI is often included in studies tracking the development of infants at increased likelihood of autism, such as the infant siblings of diagnosed children. However, the suitability of this measure has not previously been tested with community-referred infants.

Effect of Preemptive Intervention on Developmental Outcomes Among Infants Showing Early Signs of Autism: A Randomized Clinical Trial of Outcomes to DiagnosisIntervention for individuals with autism spectrum disorder (ASD) typically commences after diagnosis. No trial of an intervention administered to infants before diagnosis has shown an effect on diagnostic outcomes to date.

Delayed cortical processing of auditory stimuli in children with autism spectrum disorder: A meta-analysis of electrophysiological studiesSeveral researchers have hypothesised that individuals with Autism Spectrum Disorder (ASD) show encoding delays in their obligatory event-related potentials (ERPs)/ event-related fields (ERFs) for low-level auditory information compared to neurotypical (NT) samples. However, empirical research has yielded varied findings, such as low-level auditory processing in ASD samples being unimpaired, superior, or impaired compared to NT samples. Diverse outcomes have also been reported for studies investigating ASD-NT differences in functional lateralisation of delays.

Get it right, make it easy, see it all: Viewpoints of autistic individuals and parents of autistic individuals about the autism diagnostic process in AustraliaThe clinical process for being evaluated for an autism diagnosis is often time consuming and stressful for individuals and their caregivers. While experience of and satisfaction with the diagnostic process has been reviewed in the literature, few studies have directly investigated the viewpoints of individuals diagnosed with autism and caregivers of autistic individuals about what is important in the autism diagnostic process.
