Genetics and Alzheimer’s Disease

Like recipes, genes provide instructions about how to make something, indicating what ingredients go in and in what order. But, the environment (things outside the body like food, the air we breathe, or chemicals we are exposed to) and processes inside the body determine which ingredients are available and in what forms and quantities.

Genes play a complex and not yet fully understood role in all living things. Their part in Alzheimer’s Disease is no exception. The more researchers learn about Alzheimer’s Disease, the more they become aware of the important function genes play in the development of Alzheimer’s Disease. Recent excitement has centered around the discovery of the relationship between the apolipoprotein E (apoE) gene and Alzheimer’s Disease.
