Autism spectrum disorder (ASD) is a neurodevelopmental disability that can cause significant social, communication, and behavioral challenges yet it is defined and diagnosed by the absence or presence of behaviors described in, for example, the Diagnostic and Statistical Manual 5. Descriptions of the disorder include symptoms such as intellectual…

Excessive crowding in the visual periphery has been demonstrated in children with developmental dyslexia (DD). However, less is known about crowding in the fovea, even though foveal crowding is at least equally important, as reading is mostly accomplished through foveal vision. Here we used a special set of digit stimuli (Pelli fonts) to measure…

Children with attention-deficit/hyperactivity disorder (ADHD) may also have undiagnosed developmental coordination disorder (DCD). Prevalence rates of the ADHD/DCD comorbidity are estimated between 30% and 50%. Given the significant impact these disorders have on a child's occupational performance, lack of detection of DCD is of concern.…

ADHD affects over six million children in the U.S. and despite its prevalence, many clinicians do not accurately diagnose ADHD and do not screen for and identify the numerous conditions that can coexist and even worsen true ADHD or cause ADHD-like presentations when it does not exist. To help clinicians, this book offers three components. Part 1…

Accurate diagnosis of attention deficit/hyperactivity disorder (ADHD) in children is difficult because the major symptoms, inattentiveness and hyperactivity, can be exhibited by any child. This study finds evidence of systematic differences in diagnosis and treatment of ADHD due to third party financial incentives. In some states, due to the…

The Hong Kong Chinese version of the Autism-Spectrum Quotient-Child and Autism-Spectrum Quotient-Adolescent were examined for their psychometric properties and specificity on screening autism spectrum disorder against attention-deficit/hyperactivity disorder. This study recruited three groups of participants: typically developing children;…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field of autism research. The "2021 Summary of Advances" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles…

The purpose of this article is to provide the reader with insight into the clinical reasoning involved in the assessment and intervention planning for a child with Attention-Deficit/Hyperactivity Disorder. The reader will be guided through the authors' conceptualization of this case, and suggestions for intervention in the classroom will be…

Objective: This report examines the prevalence of developmental disabilities among children in both rural and urban areas as well as service utilization among children with developmental issues in both areas. Methods: Data from the 2015-2018 National Health Interview Survey (NHIS) were used to examine the prevalence of 10 parent- or…

Handwriting execution is based on the cognitive, kinesthetic, motor skills, and manual co-ordination skills of an individual. The deterioration in handwriting quality is a common implication of neurological disorders. Difficulty and degradation in handwriting has been attributed to the sensory motor deficits prevalent in developmental disorders.…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

This study was designed to identify items of the ADI-R that allow an early and sensitive identification of children with possible Asperger syndrome (AS). The aim was to obtain an economic short interview suitable for screening purposes. The study was based on data from a clinical sample of 5-18-year-old children and adolescents (mean age 10.9…

To evaluate evidence for motor impairment specificity in autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). Children completed performance-based assessment of motor functioning (Movement Assessment Battery for Children: MABC-2). Logistic regression models were used to predict group membership. In the models…

Currently, both the DSM-IV-TR and ICD-10 preclude the diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in cases that present with an Autism Spectrum Disorder (ASD). This criterion will be removed in the upcoming DSM-V, but the relationship between ASD and ADHD, and in particular the prevalence of ADHD among the ASD population, remains…

Objective: Many EEG studies have reported that ADHD is characterized by elevated Theta/Beta ratio (TBR). In this study we conducted a meta-analysis on the TBR in ADHD. Method: TBR data during Eyes Open from location Cz were analyzed from children/adolescents 6-18 years of age with and without ADHD. Results: Nine studies were identified with a…
