Genetics plays a large role. After advancing age, the greatest risk factor for developing Alzheimer's is having a family history of it. If you have a parent, sibling, or even child with the disease, you're more likely to get it. This risk rises with each family member who has it. Genes do play a role in Alzheimer's disease. The gene with the strongest influence on the development of Alzheimer's is called APOE-e4 (short for apolipoprotein E-e4). Scientists believe up to one-quarter of all Alzheimer's cases are due to this gene.
