Understanding Mental Retardation


Book Description

CONSUMER HEALTH . What measures can parents and advocates take to insure that people who have mental retardation live full, rewarding lives from infancy to old age?. Understanding Mental Retardation explores a diverse group of disorders from their biological roots to the everyday challenges faced by this special population and their families. With parents and those who care for people who have mental retardation in mind, Patricia Ainsworth and Pamela C. Baker write in a style that is at once accessible, informative, and sympathetic to the concerns of those affected. The authors provide practical information that will assist families and other advocates in obtaining needed services. They discuss assessment and treatment, education and employment, social and sexual adjustment, as well as regulatory and legal issues. This book covers the causes of mental retardation, the signs and symptoms of the most common forms of these disorders, and issues of prevention. For the sake of comparison, the book describes basic concepts of normal human development and references the history of Western civilization's responses to those with mental retardation. Understanding Mental Retardation sheds new light on mental illnesses that can complicate the lives of those with mental retardation, and the way symptoms of mental illness may appear confused or masked in a patient with mental retardation. Along with information on treatments and diagnoses, the book offers contact information for governmental resources, as well as a brief summary of the legal issues pertaining to mental retardation in America. Patricia Ainsworth is an assistant professor of psychiatry and human behavior at the University of Mississippi Medical Center, and has a private practice in Ridgeland, Mississippi. She is the author of Understanding Depression (University Press of Mississippi). Pamela C. Baker is director of the South Mississippi Regional Center in Long Beach, Mississippi. She is also an independent consultant in management and disabilities administration and co-editor of Embarking on a New Century: Mental Retardation at the End of the 20th Century .




Mental Retardation and Developmental Delay


Book Description

Recent advances in neuroscience and genetics have greatly expanded our understanding of the brain and of the etiological factors involved in developmental delay and mental retardation. At the same time, the human genome project has yielded a wealth of information on DNA sequencing, regulation of gene expression, epigenetics, and functional aspects of the genome, which newly propels investigation into the pathogenesis of mental retardation. This book makes readily available current knowledge on the subject and applies it to clinical medicine, providing information essential to neurologists, geneticists, physicians and pediatricians as they search for the causes of mental handicap in their patients. Introductory chapters cover normal and abnormal brain structure, neurogenesis, neuronal proliferation, and signal transduction. Latter chapters delve into discussions of both the environmental factors that may lead to neurocognitive deficits and the cytogenetic, biochemical and molecular defects specifically associated with mental retardation. One chapter reviews gene involvement in non-syndromic mental retardation, autism, and language deficits, as well as multifactorial and genetically complex inheritance. The text concludes with a clinically practical discussion of carrier detection, presymptomatic diagnosis, and treatment of various genetic diseases through enzyme therapy, substrate deprivation, and the use of hemapoietic stem cells.




Intellectual Disabilities


Book Description

Advances in biobehavioural sciences are bringing important changes in the field of intellectual disabilities. Of particular interest is the description of particular behavioural phenotypes related to but distinct from genotypes, and the extent to which they are specific. In this text, more than 20 particular genetic syndromes with marked levels of intellectual disability are identified and described from a variety of points of view, including cognitive, language, behavioural, adaptive and social and community inclusion aspects. Readers should better understand genetic intellectual disabilities and how they affect individual behaviours. Researchers and practitioners, including mental health professionals, speech-language therapists, special educators and social workers, should learn considerably more about actively researched syndromes such as Down, Williams, Fragile-X, Prader-Willi, Angelman, Rett, 5-p (Cri-du-chat), Noonan and several others, and obtain the evidence-based information they need to improve developmental, educational, occupational and residential situations, favouring inclusion for the people with intellectual disability syndromes.




Atlas of X-Linked Intellectual Disability Syndromes


Book Description

The Atlas of Intellectual Disability Syndromes presents a concise description of 150 clinically distinctive syndromes caused by genes on the X chromosome. Each entry includes photographs and a differential matrix of similar syndromes. Appendices identify syndromes with common features and provide the location or mapping limits and function of responsible genes.




Hidden Valley Road


Book Description

#1 NEW YORK TIMES BESTSELLER • OPRAH’S BOOK CLUB PICK • ONE OF GQ's TOP 50 BOOKS OF LITERARY JOURNALISM IN THE 21st CENTURY • The heartrending story of a midcentury American family with twelve children, six of them diagnosed with schizophrenia, that became science's great hope in the quest to understand the disease. "Reads like a medical detective journey and sheds light on a topic so many of us face: mental illness." —Oprah Winfrey Don and Mimi Galvin seemed to be living the American dream. After World War II, Don's work with the Air Force brought them to Colorado, where their twelve children perfectly spanned the baby boom: the oldest born in 1945, the youngest in 1965. In those years, there was an established script for a family like the Galvins--aspiration, hard work, upward mobility, domestic harmony--and they worked hard to play their parts. But behind the scenes was a different story: psychological breakdown, sudden shocking violence, hidden abuse. By the mid-1970s, six of the ten Galvin boys, one after another, were diagnosed as schizophrenic. How could all this happen to one family? What took place inside the house on Hidden Valley Road was so extraordinary that the Galvins became one of the first families to be studied by the National Institute of Mental Health. Their story offers a shadow history of the science of schizophrenia, from the era of institutionalization, lobotomy, and the schizophrenogenic mother to the search for genetic markers for the disease, always amid profound disagreements about the nature of the illness itself. And unbeknownst to the Galvins, samples of their DNA informed decades of genetic research that continues today, offering paths to treatment, prediction, and even eradication of the disease for future generations. With clarity and compassion, bestselling and award-winning author Robert Kolker uncovers one family's unforgettable legacy of suffering, love, and hope.

Mental Disorders and Disabilities Among Low-Income Children


Book Description

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.
