Treating Mental Illness and Behavior Disorders in Children and Adults with Mental Retardation
Since the 1970s, the development of normalization philosophy and the implementation of community care policies have highlighted the nature and treatment of psychiatric and behaviour disorders in people with mental retardation and rekindled the interest of scientists, psychiatric practitioners, and service providers. With these changes has grown a substantial body of new research and information on the phenomenology, epidemiology, classification, and clinical features of mental illness and behavior disorders in mentally retarded persons.
This is a comprehensive and up-to-date survey of mental retardation caused by genes on the X chromosome. Clinical and laboratory data on 130 syndromes are presented in a concise and consistent manner. Each syndrome is defined and information is provided on somatic features, growth and development, neurological signs, cognitive performance, imaging and other laboratory findings, and when possible, the nature and localization of the responsible gene. Craniofacial and other somatic findings are extensively illustrated.
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.
