Characterizing restricted and unusual interests in autistic youth

A broad range of interests characterized by unusual content and/or intensity, labeled as circumscribed interests are a core diagnostic feature of autism. Recent evidence suggests that a distinction can be drawn between interests that, although characterized by unusually high intensity and/or inflexibility, are otherwise common in terms of their content (e.g., an interest in movies or animals), labeled as restricted interests and interests that are generally not salient outside of autism (e.g., an interest in traffic lights or categorization), labeled as unusual interests.

Profiles of circumscribed interests in autistic youth

Circumscribed interests encompass a range of different interests and related behaviors that can be characterized by either a high intensity but otherwise usual topic [referred to as restricted interests] or by a focus on topics that are not salient outside of autism [referred to as unusual interests].

Autism Research

The Kids' autism research takes place at CliniKids, a centre that integrates world-class research with a clinical service for children with developmental delay and/or autism and their families.

Perinatal testosterone exposure and autistic-like traits in the general population: a longitudinal pregnancy-cohort study

Increased prenatal testosterone exposure has been hypothesized as a mechanism underlying autism spectrum disorders (ASD).

Genome-Wide Analyses of Vocabulary Size in Infancy and Toddlerhood: Associations With Attention-Deficit/Hyperactivity Disorder, Literacy, and Cognition-Related Traits

The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes, and neurodevelopmental conditions, including attention-deficit/hyperactivity disorder. 

Development of a Model of Care resource for FASD in the justice system

This article describes the development of a Model of Care resource to support youth involved with the justice system where a neurodevelopmental disability such as Fetal Alcohol Spectrum Disorder is suspected. Service staff within the Youth Justice sector were engaged in an iterative process of resource development over a 9-month period.

The effects of prenatal bisphenol A exposure on brain volume of children and young mice

Bisphenol A (BPA) is a synthetic chemical used for the manufacturing of plastics, epoxy resin, and many personal care products. This ubiquitous endocrine disruptor is detectable in the urine of over 80% of North Americans.

MACROD2 gene associated with autistic-like traits in a general population sample

The MACROD2 gene is a strong positional candidate risk factor for autistic-like traits in the general population

Prevalence and risk factors for parent-reported recurrent otitis media during early childhood

The objective was to describe the prevalence and risk factors of recurrent otitis media (rOM) in an urban Australian population at 3 years of age.

Is the broad autism phenotype in mothers of children with autism spectrum disorder exacerbated by the challenges of caring for their children?

This qualitative study of parental interviews provided a preliminary examination of whether behaviours consistent with the BAP may have been exacerbated by...
