Understanding Intellectual Disabilities

This Manual contains the most current and authoritative information and knowledge on intellectual disability, including best practice guidelines on diagnosing and classifying intellectual disability and developing a system of supports for people living with an intellectual disability. Written by a committee of 18 experts, "Intellectual Disability: Definition, Classification, and Systems of Supports" (11th edition) is based on seven years of work on: (1) a synthesis of current information and best practices regarding intellectual disability; (2) numerous reviews and critiques of the 10th edition of the American Association on Intellectual and Developmental Disabilities (aaidd) definition manual; and (3) feedback from the field regarding a series of articles published by the Committee. This is the first official aaidd definition manual with the terminology "Intellectual Disability" (formerly mental retardation).

Children living in poverty are more likely to have mental health problems, and their conditions are more likely to be severe. Of the approximately 1.3 million children who were recipients of Supplemental Security Income (SSI) disability benefits in 2013, about 50% were disabled primarily due to a mental disorder. An increase in the number of children who are recipients of SSI benefits due to mental disorders has been observed through several decades of the program beginning in 1985 and continuing through 2010. Nevertheless, less than 1% of children in the United States are recipients of SSI disability benefits for a mental disorder. At the request of the Social Security Administration, Mental Disorders and Disability Among Low-Income Children compares national trends in the number of children with mental disorders with the trends in the number of children receiving benefits from the SSI program, and describes the possible factors that may contribute to any differences between the two groups. This report provides an overview of the current status of the diagnosis and treatment of mental disorders, and the levels of impairment in the U.S. population under age 18. The report focuses on 6 mental disorders, chosen due to their prevalence and the severity of disability attributed to those disorders within the SSI disability program: attention-deficit/hyperactivity disorder, oppositional defiant disorder/conduct disorder, autism spectrum disorder, intellectual disability, learning disabilities, and mood disorders. While this report is not a comprehensive discussion of these disorders, Mental Disorders and Disability Among Low-Income Children provides the best currently available information regarding demographics, diagnosis, treatment, and expectations for the disorder time course - both the natural course and under treatment.

It is estimated that 7.2 million people in the United States have mental retardation or associated impairments - a spectrum now referred to as "intellectual disability." This book provides professionals with the latest and most reliable information on these disabilities. It utilizes a developmental perspective and reviews the various types of intellectual disabilities, discusses approaches to classification, diagnosis, and appropriate interventions, and provides information on resources that may offer additional help. Case examples are included in each section to highlight specific diagnostic and treatment issues. The emphasis in this book is on the development of the person, the provision of interventions for behavioral and emotional problems associated with intellectual disability, and the positive support necessary for self-determination. It discusses the facilitation of transitions throughout the lifespan from infancy to maturity and old age. Additionally, the book reviews evaluations for behavioral and emotional problems, genetic factors, appropriate psychosocial, medical, and pharmacological interventions, and family and community support.

Brain disordersâ€"neurological, psychiatric, and developmentalâ€"now affect at least 250 million people in the developing world, and this number is expected to rise as life expectancy increases. Yet public and private health systems in developing countries have paid relatively little attention to brain disorders. The negative attitudes, prejudice, and stigma that often surround many of these disorders have contributed to this neglect. Lacking proper diagnosis and treatment, millions of individual lives are lost to disability and death. Such conditions exact both personal and economic costs on families, communities, and nations. The report describes the causes and risk factors associated with brain disorders. It focuses on six representative brain disorders that are prevalent in developing countries: developmental disabilities, epilepsy, schizophrenia, bipolar disorder, depression, and stroke. The report makes detailed recommendations of ways to reduce the toll exacted by these six disorders. In broader strokes, the report also proposes six major strategies toward reducing the overall burden of brain disorders in the developing world.

Approximately 2.5 million people in the United States--one percent of the population--have an intellectual disability (previously referred to as mental retardation). These conditions range from genetic disorders such as Down syndrome to disabilities caused by infectious diseases and brain injury. Intellectual Disability: A Guide for Families and Professionals, by one of the country's foremost authorities on intellectual disability, is a comprehensive resource that will be of importance to anyone with a personal connection to a child or adult with a neurodevelopmental disorder. Emphasizing the humanity of persons with intellectual and related developmental disabilities, psychiatrist and pediatrician James Harris provides essential information on assessment and diagnosis of intellectual disability, treatments for specific disorders, and ways to take advantage of the wide array of services available today. The focus throughout is on the development of the person, the positive supports necessary for self-determination, and, to the extent possible, independent decision making. Harris also surveys historical attitudes toward intellectual disability, the medical community's current understanding of its causes and frequency, and the associated physical, behavioral, and psychiatric conditions (such as seizure disorder, depression, and autism) that often accompany particular types of intellectual disability. The book addresses legal, medical, mental health, and research-related issues as well as matters of spirituality, highlighting the ways in which individuals with intellectual disability can meaningfully participate in the spiritual lives of their families and their communities. Each chapter ends with a series of key points to remember, and the book concludes with a list of additional resources of further interest. Intellectual Disability is a must-read for parents and families of those with neurodevelopmental disorders, providing guidance and essential information to help their family members effectively, and to make a significant, positive difference in their lives now and in the future.

Children with developmental disabilities inhabit a gray zone: they live and learn under normal conditions in some aspects of their lives, while their "inconvenient brains" present a range of challenges in other school and life contexts. Dr. Martha Bridge Denckla provides parents and educators with general knowledge, research findings, and practical recommendations about a variety of these developmental conditions, including dyslexia, dyscalculia, ADHD, autism spectrum disorder, problems with motor coordination, and executive dysfunction. Inspired by her efforts to explain these conditions to parents over 45 years of clinical practice, she provides a science-based understanding of the issues in an accessible format. She uses the science of cognitive and behavioral neurology to help readers understand how the interrelationships of brain, environment, and behavior produce these developmental disorders, and to provide a basis for parenting and education programs based upon understanding how variations in brain development should guide plans for what is taught when to whom. Such developmentally appropriate, evidence-based, differentiated instruction within general education can diminish the demand for separate special education, and will thus serve all kinds of brains, whether "typical" or "inconvenient."

The third edition provides thorough coverage of the causes and characteristics of intellectual disabilities as well as detailed discussions of the validated instructional approaches in the field today. A revised "Future Directions" chapter explores the most recent philosophical, social, legal, medical, educational, and personal issues that professionals and people with intellectual disabilities face. All chapters have been updated with recent developments in research and the newest terminology being used in the field. This comprehensive and current introductory textbook is ideally suited for introductory or methods courses related to intellectual disabilities.
