This paper summarizes research currently being conducted on the biologic underpinnings of learning disorders, particularly dyslexia. The research findings discussed are derived from studying neuroanatomic, neurophysiologic, neurogenetic, neuroimaging, and behavioral characteristics in animal models that exhibit developmental brain anomalies and…

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…

A three-stage identification process is recommended for students suspected of having learning disabilities. This process examines discrepancy, causality, and the need for special education, and it complies with legal requirements. (Author)

Focuses on environmental issues that affect learning disabilities and provides a rationale for learning disabilities as a public health and economic-risk issue. The link between learning disabilities and poverty and the impact of low birth weight and lead poisoning are discussed. Action steps are provided. (CR)

This article reviews recent research in the field of learning disabilities and, in particular, dyslexia. It summarizes findings from numerous studies employing widely divergent methodologies that have attempted to establish the neurobiological correlates of learning disabilities and concludes that it is impossible to deny a neurobiological basis…

Describes the five learning disability research centers that make up the collaborative research network of the National Institute of Child Health and Human Development. Highlights the teams and focus of the centers, and identifies the findings of the centers and issues that need to be examined. (CR)
