Vascular dementia, caused by multiple small strokes, is the second commonest cause of dementia behind Alzheimer's disease. In recent years there has been a radical reappraisal of the concept of vascular dementia and a move away from an Alzheimer-based diagnostic paradigm towards one moreappropriately tailored for vascular disease. Vascular Cognitive Impairment presents a new definition for this class of cerebrovascular process with an emphasis on early detection, prompt treatment and the prevention of disease progression. Vascular Cognitive Impairment: Preventable Dementia presents an overview of the current state of our knowledge in this field. It reviews the historical background, prevalence, risk factors and economic consequences of the condition. In addition, the book summarises our knowledge of thepathological process, describing insight derived from genetic and imaging studies, before examining opportunities for early diagnosis, prevention and the options for management, both now, and as a result of ongoing clinical trials. With contributions from an expert team of international contributors, this book provides a comprehensive summary of the state-of-the-art in this field, providing a framework for a new understanding of a complex, disabling but Preventable condition.
