Understanding dementia
Dementia describes the effects of certain conditions and diseases on a person’s mental ability, personality and behaviour. People with dementia commonly experience problems with memory and the skills needed to carry out everyday activities. There are many different causes of dementia but Alzheimer’s disease is the most common cause. Dementia is not a normal part of ageing.
About 500,000 people in England have dementia and although it can occur at any age, it's more common in older people. About one in 20 people over 65 has dementia.
Dementia usually gets worse slowly, often over many years, and may mean that the person affected can no longer live independently. This affects both people who develop dementia and the people who care for them. It can shorten people’s lives and is an important cause of disability.
There are currently no treatments that can cure or stop the progression of most forms of dementia. However, drugs and other treatments can improve symptoms in some people, and you and your family can get the help and support you need to live with dementia.
