Why do people with dementia change so much?

Living with dementia is very hard - not just for the person who is ill, but for their family and friends.

One of the most upsetting things can be the way dementia changes a person’s relationships with the people they love.


Often, people who are living with dementia forget things that happened recently – the world as it is now – but remember things from long ago. This can feel very hurtful.

Remember that these changes are not their fault, and they are not your fault. They happen because the person’s brain is not working like it used to. They cannot see the world in the same way anymore.

Each person with dementia is different. These problems may happen after months or years, or not at all. If they do happen, they can be upsetting and hard to understand.
