A quick guide to dementia

Dementia is not something that just happens to everyone as they get older. It is caused by different illnesses.

Types of dementia

Dementia is not a disease in itself. Dementia is a word used to describe a group of symptoms that occur when brain cells stop working properly.

Support for people affected by dementia

There is support for everyone affected by dementia, including carers.

Reducing your risk of dementia

Alzheimer’s and other dementias are complex diseases. In the majority of cases they are caused by a mix of factors, called risk factors. Some of the risk factors for dementia, like our age and genetics, we cannot change. But there are steps we can take to look after our brain health, and to reduce our risk of dementia.

Genes and dementia

We are often asked about the genetics of dementia – whether diseases like Alzheimer’s can be inherited, or passed down through families.

How dementia affects everyday life

Dementia is caused by diseases that damage the brain and affect a person’s ability to think, remember and go about their day-to-day life.

For children and young people
