Intolerance of uncertainty (IU) is a multidimensional construct involving maladaptive responses to uncertainty. IU is strongly associated with autism and anxiety, yet no studies have examined its symptom profile in autistic children. This study compares IU symptom profiles in autistic and NT children and in autistic children with and without…

To propose novel differential criteria of the DSM-5 for diagnosing transient Autistic-like behaviors in children with congenital blindness as a secondary condition. Most references indicate a significantly higher prevalence of autism in children with congenital blindness compared to sighted children. These behavioral symptoms may be transient…

Children with autism frequently present with complex mental health diagnoses and psychotropic medications are often a component of comprehensive biopsychosocial treatment plans for these conditions. The purpose of this study is to provide rates and patterns of psychotropic medication use, and predictors thereof, in children and youth with autism…

Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder affecting 1 in 36 children in the United States. Given the rising prevalence and significant economic and social costs associated with ASD, it is critical that continued efforts be made towards better understanding the underlying etiology as well as…

Only one in every five children with autism is diagnosed before the age of 3 years. As a result, tens of thousands of children every year in the United States miss benefiting from early interventions and supports that could potentially optimize their lifetime outcomes. A major obstacle is the extremely limited access to high quality diagnosis. To…

Purpose: The present study aimed to assess the psychiatric characteristics of children with chronic functional constipation using the Aberrant Behavior Checklist-Japanese version and the Pervasive Developmental Disorders/Autism Society Japan Rating Scale, and to examine the frequency of autism spectrum disorder in children with chronic functional…

SYNGAP1-related ID is a genetic condition characterised by global developmental delay and epilepsy. Individuals with SYNGAP1-related ID also commonly show differences in attention and social communication/interaction and frequently receive additional diagnoses of Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). We…

This study aimed to investigate the phonological awareness (PA) skills of school age autistic children (age range = 6-12) in two parts: (1) comparing their performance on a PA task to non-autistic children with groups matched on chronological age, verbal and non-verbal cognitive skills, and (2) exploring the role of cognitive skills and autism…

Background: Few studies have explored community participation for autistic adults, with or without intellectual disability. This study aims to investigate how autistic adults participate in the community, and the childhood and adulthood factors that predict community participation in adulthood. Method: Eighty-four autistic adults (mean age 34…

Autism spectrum disorders and developmental coordination disorders are both associated with sensorimotor impairments, yet their nature and specificity remain unknown. In order to clearly distinguish the specificity between the two disorders, children with autism spectrum disorder or developmental coordination disorder presenting the same degree of…

Although neurobiologic and genetic factors figure prominently in the development of attention deficit/hyperactivity disorder (ADHD), adverse physical health experiences and conditions encountered during childhood may also play a role. Poor health is known to impact the developing brain with potential lifelong implications for behavioral issues. In…

This study aimed to systematically assess the impact of clinical and demographic variables on the diagnostic yield of Whole Exome Sequencing (WES) when applied to children with Autism Spectrum Disorder (ASD) from a consanguineous population. Ninety-seven children were included in the analysis, 63% were male and 37% were females. 77.3% had a…

Approximately 3-4 boys for every girl meet the clinical criteria for autism in studies of community diagnostic patterns and studies of autism using samples of convenience. However, girls with autism have been hypothesized to be underdiagnosed, possibly because they may present with differing symptom profiles as compared to boys. This secondary…

Autism spectrum disorder (ASD) and Developmental Coordination Disorder (DCD) are distinct clinical groups with overlapping motor features. We attempted to (1) differentiate children with ASD from those with DCD, and from those typically developing (TD) (ages 8-17; 18 ASD, 16 DCD, 20 TD) using a 5-min coloring game on a smart tablet and (2)…

Internalising symptoms are elevated in autism compared to the general population. Few studies have investigated emotional dysregulation (ED) as a potential mediator between specific transdiagnostic processes and anxiety and depression symptoms in autistic youth. In a sample of 94 autistic young people aged 5-18 years referred to a specialist…
