This review examines later life family support for adults with developmental disabilities from a life course perspective that takes into account social trends and changes in service patterns and in attitudes of families. Key issues addressed include: (1) trends affecting family caregiving, (2) health and social outcomes of life-long caregiving,…

In a review of current research and the No Child Left Behind (NCLB) legislation, this paper focuses on two specific issues: (a) how students with developmental disabilities show adequate yearly progress, including a description of the assessments in which this population may participate, and (b) the policy issues surrounding NCLB including…

This article reviews the current and changing status of residential supports for persons with intellectual and developmental disabilities (ID/DD). It examines four major trends in those supports: (1) Decreasing use of larger institutions and increasing use of community housing; (2) Decreasing size among community settings; (3) Increasing numbers…

This article extracts principles from two Surgeon General reports, "Closing the Gap: A National Blueprint to Improve the Health of Persons with Mental Retardation" (2002) and "Call to Action to Improve the Health and Wellness of Persons with Disabilities" (2005), and combines them with the Objectives from "Chapter 6 of Healthy People 2010" to…

Public financial support for intellectual disability in the United States grew from 2.3 billion in 1955 to 82.6 billion in 2004, and the federal government emerged during this period as the principal provider of such support. Notwithstanding this unprecedented growth in financial support, many inequities persist today in the distribution of…

Difficulties in finding, keeping, and ensuring the competence of the direct support workforce in community developmental disability services has long been a challenge for individuals, families, providers, and policy makers. Direct support staff recruitment, retention, and competence are widely reported as one of the most significant barriers to…

The forces shaping intellectual disability policy-making are diverse; while many of the policy issues reviewed in this issue are specific to intellectual disabilities, there are others that transcend disability-specific concerns. Our review is organized around six emerging demographic and socio-cultural trends that may directly and profoundly…

Down syndrome (DS) is the most common genetic cause of significant intellectual disability in the human population, occurring in roughly 1 in 700 live births. The ultimate cause of DS is trisomy of all or part of the set of genes located on chromosome 21. How this trisomy leads to the phenotype of DS is unclear. The completion of the DNA…

Down Syndrome (DS) caused by trisomy 21 is characterized by a variety of phenotypes and involves multiple organs. Sequencing of human chromosome 21 (HSA21) and subsequently of its orthologues on mouse chromosome 16 have created an unprecedented opportunity to explore the complex relationship between various DS phenotypes and the extra copy of…

The years 2006 and 2007 saw the publication of three new and different approaches to prevention or amelioration of Down syndrome effects on the brain and cognition. We describe the animal model systems that were critical to this progress, review these independent breakthrough studies, and discuss the implications for therapeutic approaches…

Down syndrome (DS) is the most commonly identified genetic form of mental retardation and the leading cause of specific birth defects and medical conditions. Traditional epidemiological studies to determine the prevalence, cause, and clinical significance of the syndrome have been conducted over the last 100 years. DS has been estimated to occur…

Down syndrome is the most prevalent cause of intellectual impairment associated with a genetic anomaly, in this case, trisomy of chromosome 21. It affects both physical and cognitive development and produces a characteristic phenotype, although affected individuals vary considerably with respect to severity of specific impairments. Studies…

Down syndrome (DS) is characterized by increased mortality rates, both during early and later stages of life, and age-specific mortality risk remains higher in adults with DS compared with the overall population of people with mental retardation and with typically developing populations. Causes of increased mortality rates early in life are…

Down syndrome (DS) is associated with abnormalities in multiple organ systems and a characteristic phenotype that includes numerous behavioral features. Language, however, is among the most impaired domains of functioning in DS and, perhaps, also the greatest barrier to independent meaningful inclusion in the community. In this article, we review…

Of the recent advances in education-related research in Down syndrome, the characterization of the Down syndrome behavioral phenotype has become a potentially critical tool for shaping education and intervention in this population. This article briefly reviews the literature on brain-behavior connections in Down syndrome and identifies aspects of…
