A comparison of autism prevalence trends in Denmark and Western Australia

Prevalence statistics for autism spectrum disorders (ASD) vary widely across geographical boundaries. Some variation can be explained by diagnostic methods...

Narrowing the broader autism phenotype: A study using the Communication Checklist

This study investigated whether the Communication Checklist - Adult (CC-A) could identify subtypes of social and communication dysfunction in autism probands an

Inner speech impairment in children with autism is associated with greater nonverbal than verbal skills

We present a new analysis of Whitehouse, Maybery, and Durkin's (2006, Experiment 3) data on inner speech in children with autism (CWA).

Further defining the language impairment of Autism Spectrum Disorders: Is there a Specific Language Impairment subtype?

The diagnosis of autism in a female: could it be Rett syndrome?

The aims of this study were to compare the early and subsequent clinical courses of female subjects with Rett syndrome categorised by whether...

The broader language phenotype of Autism: A comparison with Specific Language Impairment

Some individuals with autism spectrum disorders (ASD) experience linguistic difficulties similar to those found in individuals with specific language...

Parent-reported atypical development in the first year of life and age of autism diagnosis

This study examined whether parent-reported atypical development in their child's first year was associated with age of diagnosis and age when parents first needed to consult a specialist about their child's development.

The relationship between pitch contours in infant-directed speech and early signs of autism in infancy

Mother-infant interactions during the first year of life are crucial to healthy infant development. The infant-directed speech (IDS), and specifically pitch contours, used by mothers during interactions are associated with infant language and social development.

The first six months of life: A systematic review of early markers associated with later autism

There is now good evidence that behavioural signs of autism spectrum conditions (autism) emerge over the first two years of life. Identifying clear developmental differences early in life may facilitate earlier identification and intervention that can promote longer-term quality of life. Here we present a systematic review of studies investigating behavioural markers of later autism diagnosis or symptomology taken at 0-6 months.

Identification of subgroups of children in the Australian Autism Biobank using latent class analysis

The identification of reproducible subtypes within autistic populations is a priority research area in the context of neurodevelopment, to pave the way for identification of biomarkers and targeted treatment recommendations. Few previous studies have considered medical comorbidity alongside behavioural, cognitive, and psychiatric data in subgrouping analyses.
