Department of Health – Dementia: A state of the nation report on dementia care and support in England (November 2013)


  • Of the top 25 causes of years of life lost in the UK due to premature mortality between 1990 to 2010, a study found Alzheimer’s disease and other dementias had risen from 24th place to 10th, accounting for 2.6% of total years of life lost across the top 25 causes.

Hospital care:

  • An estimated 25% of hospital beds are occupied by people with dementia. People with dementia also stay in hospital for longer, are more likely to be re-admitted and more likely to die than patients admitted for the same reason.

Care homes and care at home:

  • An estimated one-third of people with dementia live in residential care with two-thirds living at home.
