Introduction: Anxiety disorders are highly prevalent in individuals with autism spectrum disorder (ASD), but knowledge is limited regarding identification and treatment of these disorders in individuals with ASD and more severe levels of intellectual disability (ID). The current case study aims to explore and describe the inpatient, psychiatric…

Diminished response to name, a potential early marker of autism spectrum disorder (ASD), may also indicate risk for other disorders characterized by attention problems, including attention-deficit/hyperactivity disorder (ADHD). Using a familial risk design, we examined whether response to name ability at 6, 12, 18, 24, and 36 months of age…

Greater understanding can increase our knowledge and intervention effectiveness for activity participation problems of children with disabilities. We examined participation difficulties of children with autism spectrum disorders (ASD) and intellectual disabilities (ID) in the 2011 Survey of Pathway to Diagnosis and Services. We utilized propensity…

Community violence and its physical health consequences are well known among youth living in urban settings. However, less is known about the cumulative effect of contextual and demographic risk factors on posttraumatic stress symptoms (PTSS) among vulnerable youth. Longitudinal data (baseline, 9-month, 21-month) were analyzed to investigate…

Background: Neurodivergence has been established as associated with a significant number of co-occurring physical conditions, particularly for autistic individuals who are at risk for increased pain, hypermobility (including Ehlers-Danlos Syndrome) and gastrointestinal problems. However, data, so far, has been focused on adults and generally…

This brief covers issues related to the assessment of dual sensory loss in students with significant cognitive disabilities, including the impact of suspected dual sensory loss on communication and learning and recommendations for assessment.

Handwriting deficits, or dysgraphia, are present in several neurodevelopmental disorders. To investigate whether dysgraphia differs according to the associated disorder, we performed a detailed analysis of handwriting in a group of French children with developmental coordination disorders (DCD), reading disorder (RD), or comorbid RD and DCD.…

Purpose: Despite having distinct etiologies, acquired apraxia of speech (AOS) and childhood apraxia of speech (CAS) share the same central diagnostic challenge (i.e., isolating markers specific to an impairment in speech motor planning/programming). The purpose of this review was to evaluate and compare the state of the evidence on approaches to…

Youth with autism spectrum disorder are at elevated risk for impaired emotion regulation and clinically impairing anxiety. A prior developmental framework posited that impaired emotion regulation leads to co-occurring psychiatric conditions such as anxiety, with outcome determined in part by autism spectrum disorder-specific moderating factors.…

Objectives: Certain heart conditions and diseases are common in Down syndrome (DS; trisomy 21), but their role in early onset dementia that is prevalent in older adults with DS has not been evaluated. To address this knowledge gap, we conducted a study of risk factors for low neurocognitive/behavioral scores obtained with a published dementia test…

Both sleep problems and unemployment are common in adults with autism spectrum disorder; however, little research has explored this relationship in this population. This study aimed to explore factors that may be associated with the presence of an International Classification of Sleep Disorders--Third Edition defined sleep disorder in adults with…

Attention Deficit Hyperactivity Disorder is a common neurodevelopmental disorder. This article examines attention-deficit/hyperactivity disorder. The focus is on the Diagnostic Criteria in DSM-5, age of onset, gender differences diagnostic features, prevalence, differential diagnosis, risk and prognostic factors and comorbidity are discussed.

Attention Deficit Hyperactivity Disorder is a common neurodevelopmental disorder. This article examines attention-deficit/hyperactivity disorder. The focus is on the Diagnostic Criteria in DSM-5 ["Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition"], age of onset, gender differences diagnostic features, prevalence,…

This study proposes a multi-informant (youth, teachers, and parents) measure of relationship quality with adults for youth with intellectual disabilities (ID). A sample of 395 youth with mild (49.15%) and moderate (50.85%) ID, aged 11-22 (M = 15.82) was recruited in Canada (French-speaking, N = 142), and Australia (English-speaking, N = 253).…

The prevalence of autism is rising, a dynamic attributed to numerous explanations (e.g. better diagnostic practices, decreased stigma). As this neurodevelopmental disability increases in visibility, disparities in its diagnostic rate grow. Female and Black populations in the United States have historically lower prevalence, are diagnosed later,…
