This is a guide for clinical psychologists and other therapists working with people who have children, and also adults with learning disabilities. It provides an overview of the definitions, causes and epidemiology of learning disabilities as well as descriptions of the main associated syndromes with learning disabilities, including Down's, Fragile-X and Autism. The book discusses the different approaches to understanding learning disabilities, using research related to development, attention, cognition, memory, learning and performance, and gives an overview of developments in service provision. A strength of the book is its discussion of legal and ethical frameworks which guide clinical practice (e.g. issues of consent, confidentiality, duty of care, restraint).
