Like all parts of the body, brains sometimes become ill. There are illnesses that stop a person's brain from working properly.
When a person has one of these illnesses, their brain starts to have problems doing all the jobs it has to do.
The person may start to have problems with remembering, thinking, speaking or seeing what or where things are. They might say or do things that seem strange to us. They may find it more difficult to do everyday things. They may not seem like the same person they used to be.
Doctors use the word dementia to describe these different problems.
