"Dementia: A Very Short Introduction explains how dementia is diagnosed, its different types and symptoms, and its effects on sufferers and their families. Why is dementia resistant to treatment? Why has the most successful scientific hypothesis not led to a cure? Are there variations between different countries, and given the rise in the ageing population, are there more or less cases than we think? This VSI looks at the history of dementia research and examines the genetic, physiological, and environmental risk factors and how individuals might reduce them. It also investigates developments in diagnosis and symptom management, and the economic and political context of dementia care"--Provided by publisher.
