As more people are living longer this growing number of older people means an increase in mental health problems. Twenty-five per cent of people over 85 develop dementia and between ten and sixteen per cent of those over 65 develop clinical depression. In addition, people who developed severe and enduring mental health problems such as schizophrenia when young are now growing older (Audit Commission, 2000). Most people with dementia live in the community. About half are cared for at home by a family carer, usually a spouse or adult child (Keady & Nolan, 1995).
