What is Dementia?

Dementia is caused by a number of diseases that affect the brain. The most common is Alzheimer's but diseases also include vascular dementiadementia with Lewy bodies and Pick's disease.

Different types of dementia affect the brain at different rates and in different ways, but other things like someone's personal circumstances, the people around them and the environment in which they live, will affect their experience of dementia. Dementia progresses in a way that is unique to each individual.

The word 'dementia' describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life. A person with dementia may also experience changes in their mood or behaviour. 

It is true that more people over 65 have dementia but it is not exclusively an older person's disease; younger people get dementia too.
