This book discusses in detail the genetic causes and implications, prevalence, physical characteristics, cognitive profiles, speech and language, medical complications, and behaviors of four major syndromes (Down, Williams, fragile X, and Prader-Willi) an

This remarkable publication focuses on the importance of genetics in mental retardation, investigating the extent to which molecular diagnostic capability and the understanding of genetic causes have improved over recent years. As a result, clinical evaluation and diagnostic laboratory practice are now undergoing an unprecedented period of change. In a single volume, a unique combination of key individuals and world-class clinical, diagnostic and research-based experts share specialized, state-of the-art knowledge in this field. The parents' perspective lies behind chapters dealing with issues such as: - Classification nomenclature - Well-known syndromes - How modern technologies have resulted in newly identified syndromes - How genome architecture can influence disease - Guidelines for clinical evaluation - Valuable database resources for clinical, diagnostic and research departments - Challenges involved in data interpretation and determining clinical relevance - Genetic overlaps with autism and schizophrenia - Processes of health service implementation Genetics of Mental Retardation is an invaluable resource for researchers and students with an active interest in the field. Furthermore, consultants and trainees in clinical genetics and pediatrics, and researchers working in clinical genetics laboratories will benefit from these reviews.

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.

Increasing interest over recent years in the study of the influences of environment and genetic factors on behavioural disorder has come from a wide range of disciplines. These studies have subsequently been focused through the foundation of the Society for the Study of Behavioural Phenotypes, which forms the basis for assimilating new information and coordinating future research in this field. This volume from founder members of the society presents a distillation of thinking and reviews appropriate measurement schedules. Including research findings, explanation of concepts, genetic scientific techniques and methodological issues, this work will be welcomed by those with an interest in behavioural disorder at every level.

This new book is an up-to-date review of the clinical, epidemiological, and cytogenetic aspects of the fragile X (Martin-Bell) syndrome--the most common genetic cause of mental retardation after Down syndrome. The book includes the latest research findings concerning diagnosis on the basis of the appearance of a fragile site in cultured lymphocytes. It assumes little prior knowledge of the subject, and provides a clearly written, easy-to-understand discussion previously unavailable in a single reference source. The book will be of special interest to molecular biologists, cytogeneticists, medical geneticists, and clinicians and other professionals working with the mentally handicapped.

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.

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.
