Dementia is a global concern but it is most often seen in wealthier countries, where people are likely to live into very old age. The Alzheimer’s Society (2014) reports there are over 850,000 people living with dementia in the UK today. Of these, approximately, 42,000 are people with young onset dementia, which affects people under the age of 65. As a person’s age increases, so does the risk of them developing dementia. It is estimated that the number of people living with dementia in the UK by 2025 will rise to over one million. Rates of diagnosis are improving but many people with dementia are thought to still be undiagnosed.
