Genes and dementia
Dementia information
These pages give an overview of what genes are and how they are involved in the different diseases that cause dementia. You will also find information about genetic testing for dementia.
In this section:
Genes determine our traits, such as our eye colour and height. In some cases, they can also determine whether we develop a disease, like Alzheimer’s, or not. They are “passed on” or inherited from our parents.
Every cell in our body contains thousands of genes. Genes are the complex building instructions for each cell in our body. Proteins are the building blocks which make up every part of our body’s cells.
These cells make up our organs, which are like rooms in a house where each has a different purpose. And all of these organs make up our body, which is the finished structure – like a house.
