It is important to note that if you take a genetic test and the results indicate you have APOE4, the genetic variant associated with late-onset Alzheimer’s disease, you are not destined to develop Alzheimer’s. “It’s not a diagnosis,” said Ramos, “And it’s just one factor. Your chance of getting late-onset Alzheimer’s is a mix of your environment, family history and DNA. That can be a complicated message to tease out.” Even if you have one copy of the APOE4 variant, you are still unlikely to develop Alzheimer’s. For example, a woman with a single copy of APOE4 has a five to seven percent chance of getting Alzheimer’s by the age of 75. The rate increases to between 27 and 30 percent by age 85. (However, for women with two copies of the variant the risk increases to 60 percent by age 85.) In addition, there are a number of potential

It is now easy and relatively inexpensive for consumers to take tests that reveal basic information about their genetic health and ancestry. The market for such tests is booming, a trend that will likely continue following the U.S. Food and Drug Administration’s recent streamlining of the approval process for bringing tests to market. One of the more popular tests, 23andMe, costs $199 and can reveal a number of genetic predispositions. For example, you can discover if you are predisposed to lactose intolerance or a tendency to drink a lot of coffee. It can also tell you whether or not you have one of the genetic markers that increase your chance of developing Alzheimer’s disease. The popularity of 23andMe and similar tests is understandable. If you know you have a risk for certain medical conditions, you can take steps to try and prevent them. You can avoid specific foods, take the
