This unit examines the evidence base for, and the potential impact of, community-level initiatives aimed at (1) reducing the incidence of dementia in the general population, and (2) improving quality of life for those living with dementia. These are classed as public health approaches to dementia. The large- scale impact of dementia on societies, both current and forecast, is surveyed, and used to inform an evaluation of effective public health strategies initiatives designed to reduce this impact. Initiatives investigated include community-wide inclusion and support of people living with dementia and their carers, such as dementia friendly communities and environments, and dementia risk reduction efforts. You will be encouraged to develop skills to explain evidence, arguments and advice on dementia support and prevention in a variety of community contexts.This unit of study is part of the Postgraduate Studies in Dementia Program, offered by the University of Tasmania.
