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…

Attention deficit hyperactivity disorder (ADHD) is the most common neurobehavioral disorder diagnosed in U.S. children (1). While this disorder is most often diagnosed in children when they are in elementary school, it is increasingly being identified in preschool children (2-5). This report describes the prevalence of diagnosed ADHD among…

It is now recognized that there is a very high prevalence of psychological disorders among children and adolescents and relatively few receive psychological treatment. In the current article, we present the argument that levels of distress and dysfunction among young people are substantially underestimated and the prevalence of psychological…

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…

This guide to Asperger syndrome first reviews clinical features (such as social isolation and a lack of empathy) and diagnosis. It then considers epidemiology and prevalence data and offers a case study. Principles of management and education are discussed, including use of structured, routine regimens, focus on the child's strengths, guided…

Six issues relating to assessment of gifted/learning disabled (GLD) students are discussed: (1) incidence; (2) cut-off IQ scores; (3) barriers to identification; (4) use of the Wechsler Intelligence Scale for Children--Revised; (5) differentiation between GLD and underachieving gifted; (6) qualitative differences between GLD, gifted, and learning…

This paper reviews ongoing research designed to specify the cognitive, behavioral, and neuroanatomical phenotypes of specific genetic etiologies of learning disability. The genetic disorders at the focus of the research include reading disability, neurofibromatosis type 1, Tourette syndrome, and fragile X syndrome. Implications for identifying…

The prevalence of learning disabilities (LD) was studied in 233 students (ages 6-16) newly identified with behavioral disorders. Overall, 53.2 percent met at least one LD definition, ranging from 15.9 percent for low achievement to 42.9 percent for regression. Almost one-quarter showed overlapping between low achievement and discrepancy…

A study involving 2,929 Head Start children found that 8% transitioned into special education during kindergarten and showed divergent patterns of receptive language development. Head Start children in special education differed from children in general education based on child demographic, intellectual, behavioral, and health factors. (Contains…

A survey of 1 school district found 136 students (out of 14,229) with attention deficit-hyperactivity disorder (ADHD) of which 77 were receiving special education services; 40 were also identified as behavior disordered, 22 as learning disabled, and 7 as mildly mentally retarded. Fifty students were in general education classrooms with resource…

This paper provides a brief historical outline of attention deficit hyperactivity disorder (ADHD), its definition, its behavioral characteristics, and a guide to creating successful learning environments for these students. Diagnostic criteria for ADHD are listed and discussed, and incidence figures of 3 to 5 percent of all school-age children are…

This fact sheet summarizes basic information on Attention Deficit Disorders (ADD), including prevalence and characteristics, causes, identification, treatment, outcomes, and suggestions. Children with ADD comprise approximately 3-5 percent of the school age population, with boys significantly outnumbering girls. Of 14 characteristics of ADD, the…

A review of 10 studies on the rates of referral for intervention or assessment of students from three racial groups (Caucasian, African American, and Hispanic), found the mean risk ratios comparing the referral rates between African American and Caucasian students were significantly different from zero. (Contains references.) (Author/CR)

Basic information for regular classroom teachers with students who are both gifted and learning disabled covers definition of this population; incidence; characteristics; and six teaching strategies, such as flexibility in how student demonstrates mastery of material, adapting for reading differences, and using attention-directing techniques. A…
