The brain and dementia

Dementia occurs when the brain is damaged by disease

Knowing more about the brain may help someone caring for a person with dementia to understand the condition and support them better. There has been a lot of research into how the brain works. However, not all the details are clear and more research is needed. These pages explain which areas of the brain are thought to be responsible for which skills and abilities. They explain how changes in the brain of someone with dementia relate to the changes that they - and those around them - may notice as the condition progresses. They will be helpful for anyone who wants to find out more about how the brain is affected in dementia.

The brain is incredibly complex and this section of our site contains a lot of information about how the brain is thought to function. For more about how the brain works and the effects of dementia, see our set of videos.
