Is dementia becoming more common?

Dementia is not a disease itself, but a word used to describe a set of symptoms. Dementia is caused by diseases that affect the brain, and the symptoms of dementia can vary a great deal. They can include problems with memory, decision-making, communication, confusion, changes in mood and behaviour, and hallucinations.

Dementia can be caused by a number of different diseases, with Alzheimer’s disease being the most common. Other causes of dementia include vascular dementia, dementia with Lewy bodies and frontotemporal dementia. In some cases, a person’s dementia is caused by more than one disease, such as Alzheimer’s disease and vascular dementia. This is often called mixed dementia.
