Sadly, there are no treatments that can stop the illnesses that cause dementia, or fix the problems they cause in the brain. Once a person has dementia, they will have it for the rest of their life.
A person with dementia needs help and care from other people. Their family and friends often help. Doctors, nurses and carers help too.
Doctors, nurses and carers cannot cure dementia yet, but they can help to make life easier for people with dementia.
