Developmental language disorder (DLD) is a language deficit affecting approximately 7% of the general population and does not associate with any hearing impairment, neurological damage, or mental disorder. In DLD, the complications arise over time due to the learning difficulties experienced, which causes eventual cognitive delay compared to…

Purpose: Developmental language disorder (DLD) is a lifelong condition that when impacting educational performance is identified and serviced through U.S. schools as outlined in the Individuals with Disabilities Education Act. A few examples of educational categories that refer to DLD are (a) speech or language impairment (S/LI) and (b) specific…

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.…

This article examines issues related to identification of children with specific learning disorders (SLDs). The focus is on the diagnostic criteria in DSM-5. Diagnostic features, associated features supporting diagnosis, and prevalence are discussed.

This article examines issues related to identification of children with specific learning disorders (SLDs). The focus is on the Diagnostic Criteria in DSM-5 ["Diagnostic and Statistical Manual of Mental Disorders, 5th Edition"]. Diagnostic features, associated features supporting diagnosis, and prevalence are discussed.

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…

A relationship between motor and mathematical skills has been shown by previous research. However, the question of whether subtypes can be differentiated within developmental coordination disorder (DCD) and/or mathematical learning disability (MLD) remains unresolved. In a sample of children with and without DCD and/or MLD, a data-driven…

The study of children with Developmental Coordination Disorder (DCD) has emerged as a vibrant line of inquiry over the last three decades. DCD is defined as a neurodevelopmental condition characterized by poor motor proficiency that interferes with a child's activities of daily living (sometimes also known as dyspraxia). Common symptoms include…

Earlier indentification has increased the number of infants identified with hearing loss. A significant and growing proportion of children who are D/deaf or hard of hearing have a disability (DWD). Literature related to infants and toddlers who are DWD is scarce because of the heterogeneity of the population and because many disabilities may go…

This study provides a qualitative examination of the original tenets of Labelling Theory (LT) within the realm of education using a relatively new medical label, developmental coordination disorder. Labelling Theory, although initially proposed in the areas of crime and deviance, has been applied to mental illness and educational labels. However,…

Chromosomal microarray analysis (CMA) has emerged as a powerful new tool to identify genomic abnormalities associated with a wide range of developmental disabilities including congenital malformations, cognitive impairment, and behavioral abnormalities. CMA includes array comparative genomic hybridization (CGH) and single nucleotide polymorphism…

Understanding the precursors and early indicators of dyslexia is key to early identification and effective intervention. Now there's a single research volume that brings together the very latest knowledge on the earliest stages of dyslexia and the diverse genetic, neurobiological, and cognitive factors that may contribute to it. Based on findings…

The aim was to characterize the panorama of developmental disorders in 208 preschool children with a clinical diagnosis of autism spectrum disorder (ASD), referred to a specialized centre, the Autism Centre for Young Children (ACYC), for intervention. At the centre, a research team examined all children according to structured protocols and…

It is argued the proposed definition of dyslexia is restricted to developmental dyslexia in which a student struggles to learn to read and does not apply to acquired dyslexia in which a previously normal reader loses reading functions. The need for classification schemes for defining specific learning disabilities is emphasized. (Contains…

The recent reauthorization of the Individuals With Disabilities Education Improvement Act of 2004 (IDEA; 2004) is first discussed in its historical context. Then, a programmatic line of research (funded by the National Institute of Child Health and Human Development since 1989) is described that is relevant to a proposed model for universal…
