Dementia is not something that just happens to everyone as they get older. It is caused by different illnesses.
What is dementia?
Our brains control everything we think, feel, say and do. They also store our memories for us.
There are diseases that stop a person’s brain from working properly. When a person has one of these diseases, they may have problems remembering, thinking and speaking. They might say or do things that seem strange to others, and find it harder to do everyday things. They may not seem like the person they used to be.
Doctors use the word dementia to describe these different problems.
Why does it happen?
Dementia is not something that just happens to everyone as they get older. It is caused by different diseases.
Most people with dementia have Alzheimer’s disease or vascular dementia but there are other types too
These diseases affect different parts of the brain, so they affect people in different ways.
At the moment we don’t know why one person may get one of these diseases while another person may not. Doctors and scientists are working hard to find out more about dementia.
How does dementia affect someone?
Most of us forget things from time to time, like where we left our keys. This does not mean we have dementia. Symptoms of dementia slowly get worse until they get in the way of daily life.
When people start to get dementia, you might see some of these things happen:
Forgetting recent events, names and faces.
Asking the same questions often in a short space of time.
Putting things in the wrong place.
Finding it hard to pay attention or make simple decisions.
Not being sure about the date or time of day.
Getting lost, mostly in places that are new.
Finding it hard to use the right words or understand other people’s words.
Changes in how someone feels, like becoming sad or easily upset, or losing interest in things.
As dementia gets worse, people may have trouble speaking clearly or telling you what they need or how they feel. They may find it hard to eat and drink, wash and dress themselves, and go to the toilet without help.

Is there a cure?
At the moment there is no cure for dementia. Once a person has dementia, they will have it for the rest of their life.
There are some medicines that can help for a while, by making day-to-day life a little easier. There may also be group activities people can take part in to help them live better with their symptoms. Your doctor can tell you more about these.
Unfortunately there are no medicines at the moment that can stop these diseases so people will continue to get worse over time.

Where to go for help
If you think someone you know may have dementia, encourage them to go to see their doctor.

If the doctor says anything you’re not sure about, speak up and ask them to explain.
