Clinicians, educators and other specialists who work with young people with intellectual disabilities are increasingly aware of the extent to which their clients’ behaviours are shaped by the respective causal syndrome. This book is a practical response to the need for interventions and ongoing care programmes to take account of this within the context of coordinated multimodal case planning. An international team of experts drawn from child health, special education, psychology, psychiatry and related disciplines explores general principles of case management, in addition to giving consideration to a large number of individual syndromes, resulting in a comprehensive review of the subject. All of the authors have been involved in original research on the themes explored, and in the development of coherent service responses to the challenges posed by behavioural phenotypes. This will be essential reading for all professionals engaged in the care and management of people with intellectual disabilities.
