When we were very young, we didn’t know how to walk, talk, play, eat or go to the toilet. We had to learn these things. As we grow, we keep learning new things every day. All this learning is stored in our brains.
When a person has dementia, their brain starts to forget some of the things they have learned and has trouble helping them do other things. They might forget words and names. They might forget what they’ve just said, and say the same thing over and over again. They may get muddled up and have trouble working out what to do and when.
As their brain gets more unwell, they start to have trouble with more and more things. They might have trouble working out where they are, and get lost easily. They might not be able to recognise who people are – even people that they love. They might find it really hard to do things that used to be easy for them.
Over time, people with dementia can find it tricky to do things like talking, getting dressed, washing, eating or going to the toilet. They need even more help and care from other people.
