The facts about the growing number of people with dementia in the UK and the associated costs are firmly established. It is well known that dementia is a significant and growing driver of demand for health and social care. The cost of dementia in the UK in 2010 was estimated to be £20 billion and this is expected to grow to over £27 billion by 2018. It is also clear that health and social care budgets are under extreme pressure and there is an urgent need to improve the cost-effectiveness of services.
