This article addresses the nature of dyslexia and best practices for identification and treatment within the context of multitier systems of support (MTSS). We initially review proposed definitions of dyslexia to identify key commonalities and differences in proposed attributes. We then review empirical evidence for proposed definitional…

To help educators understand the cognitive and behavioral sequelae of cerebral injury, the neuropathology of traumatic brain injury and the main neuropathological features resulting from trauma-related brain damage are reviewed. A glossary with definitions of 37 neurological terms is appended. (Author/DB)

The paper evaluates the empirical and theoretical basis upon which several recent studies reject the hypothesis of a visual-perceptual deficit in reading disabilities. (Author)

This article introduces four papers (and responses to them) originally given at an April 1990 conference on the identification and treatment of dyslexia. Noted is the lack of consensus on what dyslexia is, how the condition comes to be, and what the nature of educational intervention ought to be, though developmental views are seen to predominate.…

Reading instruction for learning disabled students is discussed, with emphasis on the instruction provided by the general classroom teacher and by the reading specialist with cooperation from other personnel. (IM)

Reviews the methods, technologies, and operating tenets of case studies of reading disabilities completed during the late 19th and early 20th centuries. Results suggest that the assumptions of anatomical and functional modularity for cortical processes become guiding principles for diagnosing and correcting reading difficulties. (Author/CR)

This study of 640 twins with reading disability and 436 controls (mean age 12) examined external validity of the distinction between specific reading retardation and reading backwardness, in 3 domains: genetic etiology, sex ratio and clinical correlates, and neuropsychological profiles. There was no evidence of differential genetic etiology of the…

Considers whether mental retardation can be considered a concomitant disability associated with learning disabilities or whether these are mutually exclusive categories. Emerging issues concerning definitions, classification, etiology, and lifelong development of these students are addressed. Also discussed are appropriate educational curricula,…
