*Highly Commended in the Health and Social Care category at the 2012 British Medical Association Book Awards*Behaviours that challenge can significantly interfere with the quality of life of a person with dementia, as well as that of those who live with and care for them. Yet there is a great deal of confusion surrounding how such behaviours should be addressed. This book provides theory and practical guidance on the assessment and treatment of behaviours that challenge in dementia, with a particular emphasis on non-pharmacological approaches. The author describes the different categories and causes of challenging behaviour in people with dementia, and provides tried-and-tested models which will aid identification, assessment and treatment. A thorough evaluation of the use of psychotropic medication is provided, as well as of a wide range of psychological and biopsychosocial interventions. The book contains useful tools and protocol derived from the author's work at a specialist challenging behaviour unit, as well as case studies which demonstrate how the various models may be used in practice. This will be an invaluable resource for any professional involved in the assessment and treatment of behaviours that challenge in people with dementia, including psychiatrists, psychologists, community psychiatric nurses, GPs and occupational therapists. It will also be of interest to those involved in commissioning, providing and managing services.
