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…

This brief, co-produced by the National Center on Deaf-Blindness (NCDB) and Accessible Teaching, Learning, and Assessment Systems (ATLAS), provides important information about students with dual sensory loss who also have significant cognitive disabilities, as well as recommendations for identification and implications for instruction. The…

The present study performed a systematic comparison of DSM-5 and ICD-11 diagnostic criteria for reading disability. We quantitatively investigated the consequences of using DSM-5 or ICD-11, and of the different ways of implementing each diagnostic criterion on the prevalence of reading disability. We did so in a representative sample of the…

All but seven U.S. states have laws that govern some aspects of dyslexia screening, intervention, or teacher training in public schools. However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better…

Dysphagia is the clinical expression of disruption of the synchronized activity surrounding the normal swallowing mechanism. It results from a large number of causes including neurologic, myopathic, metabolic, inflammatory/autoimmune, infectious, structural, iatrogenic, and psychiatric diseases. It can have a significant impact on social and…

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…

Based on the latest U.S. Department of Education data, this article presents the enrollment figures for students identified with specific learning disabilities (SLD) under the Individuals with Disabilities Education Act (IDEA) for the school years from 1995-1996 to 2011-2012. The figures for each year are (a) the number of students with SLD ages 6…

The etiology of autism spectrum disorders is unknown but there are claims of increasing prevalence in many countries. Despite more than a decade of epidemiological investigation, it is still unclear whether the rising trend in prevalence reflects a true increase or changes in diagnostic trends and improvements in case ascertainment. This paper…

This study examined the consequences of classifying postsecondary students as learning disabled (LD) using five objective sets of criteria: IQ-achievement discrepancies (1.0 to 1.49 SD, 1.5 to 1.99 SD, and greater than or equal to 2.0 SD), DSM-IV criteria, and chronic educational impairment beginning in childhood. The participants were 378…

A study investigated whether higher prevalence of reading disabilities among boys is related to gender bias in the prediction of reading from IQ. Data from 1,139 New Zealand children (collected during ages 5-13) indicate a significant intercept bias. Boys' predicted reading scores were systematically overestimated, thereby inflating IQ-reading…

A study examined the validity of the Gilliam Autism Rating Scale (GARS) with 119 children (ages 3-10) with strict DSM-IV (Diagnostic Statistical Manual of Mental Disorders-IV) diagnoses of autism. The GARS consistently underestimated the likelihood that children would be classified as having autism. Limitations of ratings scales and of the GARS…

A study involving 4,141 schools investigated gender and race/ethnicity disproportionality among students identified as having learning disabilities. There was a clear association between ethnicity and gender and the odds of being identified as a student with learning disabilities. School sociodemographic factors also associated with the proportion…

This paper examines statistics that appear to show a 20 percent decline in the number of students identified as mildly mentally retarded. Evidence is provided which suggests that the primary reason for these declining figures is that these children are being classified as learning disabled. Relatively loose criteria for the learning disabilities…

Reviews the debate from the standpoint of entitlement about the education of children who are classified as seriously emotionally disturbed or socially maladjusted. It examines how research has supported or contradicted the notion of entitlement from the standpoint of prevalence, classification, intervention, and cost. Ethical guidelines are…

Ohio has used 12 disability categories to report and fund students with special education needs. In June of 2001, the Ohio General Assembly divided the "other health handicapped" category into 2 categories: "other health handicapped-minor" and "other health handicapped-major." Students identified in the major category…
