Mental retardation is a term for a pattern of persistently slow learning of basic motor and language skills ("milestones") during childhood, and a significantly below-normal global intellectual capacity as an adult. One common criterion for diagnosis of mental retardation is a tested intelligence quotient (IQ) of 70 or below. This book presents leading-edge research from around the world.

Language and communication problems have long figured prominently in the definition of mental retardation. Volume 27 of the International Review of Research in Mental Retardation focuses exclusively on these language and communication issues. The pace of research on language learning and use in mental retardation has increased in recent years and taken new direction. This revitalization has been fueled by three factors: 1) advances in genetic technologies allowing investigation of the behavioral phenotypes of well-defined syndromes, 2) an increased emphasis on maximizing abilities of individuals with mental retardation to live and succeed in a broader range of contexts and settings, and 3) theoretical debates concerning the mechanisms of language development and the nature of the human mind. Contents in Language and Communication in Mental Retardation include syndromes (e.g., Down syndrome, Williams syndrome), domains of language skill (e.g., reading), and intervention strategies. - Contains the most current research on genetic syndromes, including Williams syndrome, Down syndrome, and fragile X syndrome - Outlines the most current research on language and communication intervention for persons with mental retardation - Authors consider the implications of the research reviewed for both theory and clinical practice - Authors bring state-of-the-art knowledge of cognitive science, developmental science, linguistic, and behavioral genetics to bear on important questions about language and mental retardation - Includes new research on long-studied conditions (e.g., Down syndrome) and disorders that are of only recent interest to child language researchers (e.g., fetal alcohol syndrome) - Includes a consideration of nonverbal, as well as verbal, communication

This book brings together the latest research in the battle against autism. Autism is a complex developmental disability that typically appears during the first three years of life. The result of a neurological disorder that affects the functioning of the brain, autism and its associated behaviours have been estimated to occur in as many as 2 to 6 in 1,000 individuals. Autism is four times more prevalent in boys than girls and knows no racial, ethnic, or social boundaries. Autism is a spectrum disorder. The symptoms and characteristics of autism can present themselves in a wide variety of combinations, from mild to severe. Although autism is defined by a certain set of behaviours, children and adults can exhibit any combination of the behaviours in any degree of severity. People with autism process and respond to information in unique ways. In some cases, aggressive and/or self-injurious behaviour may be present.

Current estimates suggest that between one and three percent of people living in the United States will receive a diagnosis of mental retardation. Mental retardation, a condition characterized by deficits in intellectual capabilities and adaptive behavior, can be particularly hard to diagnose in the mild range of the disability. The U.S. Social Security Administration (SSA) provides income support and medical benefits to individuals with cognitive limitations who experience significant problems in their ability to perform work and may therefore be in need of governmental support. Addressing the concern that SSA's current procedures are consistent with current scientific and professional practices, this book evaluates the process used by SSA to determine eligibility for these benefits. It examines the adequacy of the SSA definition of mental retardation and its current procedures for assessing intellectual capabilities, discusses adaptive behavior and its assessment, advises on ways to combine intellectual and adaptive assessment to provide a complete profile of an individual's capabilities, and clarifies ways to differentiate mental retardation from other conditions.

This handbook addresses behavior problems and mental health disorders in persons with intellectual disabilities. It provides an overview of the history of dual diagnosis and related theories, ethics, diagnostic systems, mental health disorders, and challenging behaviors. The handbook examines general clinical issues, such as the effects of cognitive performance on the choice of assessment and treatment methods, service delivery systems, education models, risk factors, functional assessment, and structured interviews. Chapters provide a much-needed reference for practitioners and practitioners in training. The applied focus of the book continues with assessment/diagnosis sections of mental health disorders, and challenging behaviors. In addition, chapters describe treatments for discrete mental health and behavior problems, such as intellectual disabilities, severe psychopathology, autism, ADHD, substance abuse, and aggression. Topics featured in this handbook include: Genetic disorders and dual diagnosis. Assessment of anxiety in persons with dual diagnosis. Aging with intellectual disabilities. Feeding problems and assessment in individuals with dual diagnosis. Pica in individuals with intellectual disability. Treatment of social skills in dual diagnosis. The Handbook of Dual Diagnosis is an essential reference for researchers, graduate students, clinicians and related therapists and professionals in clinical child and school psychology, child and adolescent psychiatry, social work, developmental psychology, behavioral therapy/rehabilitation, pediatrics, and special education.

Psychological Therapies for Adults with Intellectual Disabilities brings together contributions from leading proponents of psychological therapies for people with intellectual disabilities, which offer key information on the nature and prevalence of psychological and mental health problems, the delivery of treatment approaches, and the effectiveness of treatment. Offers a detailed guide to available therapies for adults with intellectual disabilities Includes case illustrations to demonstrate therapies in action Provides up-to-date coverage of current research in the field Puts forward a consideration of the wider contexts for psychological therapy including the relationship with social deprivation, general health, and the cost effectiveness of treatment Places individual interventions in the context of the person’s immediate social network including families and carers Includes contributions from leading proponents from around the world
