Dementia is not a natural part of the ageing process. It's caused by illnesses that affect the brain.

​

Dementia is an umbrella term for over 100 different types of disease and symptoms. It is possible to have more than one type. What all these diseases have in common is that they damage brain cells, so the brain cannot work as well as it should.

​

Dementia can affect every area of human thinking, feeling and behaviour, but each person with dementia is different. 

 

How the illness affects someone depends on a range of factors, including which area of the brain is damaged.

  

We do not yet know exactly what causes dementia. Medical researchers all over the world are working to find the cause and develop treatments.
