What to expect

Most of the illnesses that cause dementia are progressive, which means that the problems they cause become gradually worse. Sadly, there is no way to stop or reverse the damage that these illnesses do to a person’s brain.

A person who is living with dementia will change over time. Nobody can say for sure what the changes will be, or when they will happen, because everyone experiences dementia in a different way. In the early stages of dementia, some people have a lot of difficulties with some things but can still do other things well. For example, they may become very forgetful but their personality and sense of humour may be normal. Or it may just be their speech or behaviour that changes initially, while their memory seems to be fine.
