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.

Exploring the Experience of Seeking an Autism Diagnosis as an Adult

Emerging research suggests that seeking an autism diagnosis as an adult is usually difficult and time-consuming but brings relief once a diagnosis is made. This study explored the experience of the pathway to an autism diagnosis during adulthood for adults living in Australia.

Developmental Vitamin D Deficiency in Pregnant Rats Does Not Induce Preeclampsia

Preeclampsia is a pregnancy disorder characterized by hypertension. Epidemiological studies have associated preeclampsia with an increased risk of neurodevelopmental disorders in offspring, such as autism and schizophrenia. Preeclampsia has also been linked with maternal vitamin D deficiency, another candidate risk factor also associated with autism.

An evidence-based framework for determining the optimal amount of intervention for autistic children

The provision of timely, effective, and socially valid non-pharmacological intervention is at the core of efforts to support the development of young autistic children. These efforts are intended to support children to develop skills, empower their caregivers, and lay the foundation for optimal choice, independence, and quality of life into adulthood.

A Survey of Autistic Adults from New Zealand on the Autism Diagnostic Process During Adolescence and Adulthood

The diagnostic experiences of autistic adults in New Zealand have not been investigated and little is known globally about autistic adults' satisfaction with the autism diagnostic process. This study describes the diagnostic experiences of 70 autistic adults living in New Zealand and explores how these experiences are related to satisfaction during three stages of the diagnostic process. The results show that autistic adults were reasonably satisfied with the early query and diagnostic assessment stages, but were dissatisfied with the post-diagnostic support stage, with significant unmet needs. Dissatisfaction during the post-diagnostic support stage was also related to satisfaction during previous stages and poor coordination of supports. Suggestions are made on how to improve the autism diagnostic pathway for autistic adults in New Zealand.

Parent-reported Early Atypical Development and Age of Diagnosis for Children with Co-occurring Autism and ADHD

Autism and attention-deficit/hyperactivity disorder (ADHD) often co-occur. This survey of 288 New Zealand parents of children diagnosed with autism, ADHD, or both conditions, examined the relations between age of diagnosis and early atypical development, the age specialist consultation was needed and types of specialists seen.
