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 managed. This much-needed 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 summarises the different categories and causes of challenging behaviours in 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 an in-depth summary 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 have been.
