This type of Alzheimer’s testing is more high tech, but it is still not completely conclusive. Alzheimer’s disease is a condition that is devastating for both individuals and their families, and for society and our health care system. In addition, clinicians are concerned about the potential for patient discrimination. Some feel that treatment needs to occur prior to the onset of dementia to be effective. Ultimately, the choice of whether to get a genetic test remains a personal one – all the more reason it’s important to be informed about the pros and cons of Alzheimer’s screening and what doctors know about your risk for the disease and whether viable treatment options are available. 1. In the opinion of Dr. Power, who speaks about dementia around the world, these are the possible pros and cons to getting the genetic test for Alzheimer’s disease: For those who want to engage in research trials to treat or prevent a familial form of dementia, a test would be useful. 1.

There might be some type of direct connection or link between these factors and Alzheimer’s disease.
The most common risk gene is called APOE.
Being Patient spoke with Tyrone and Dr. Sabbagh about genetic testing, the potential for further genetic research, what people should know about living with the ApoE4 gene and the lifestyle changes that can influence an individual’s risk. Until you are actually diagnosed, it is difficult to process that a debilitating disorder could be a reality of your life.

Brief Cognitive Test This test is almost always a preliminary test, because the results can never be conclusive. This test is designed to find a different cause of memory problems. In addition to advancing age, there are known genetic risk factors associated with Alzheimer’s, with a gene called ApoE4 being the most important of all of them. The vast majority of Alzheimer’s cases have late onset, or after age 65, and advancing age is the greatest risk factor. Genetic Testing for Alzheimer's Has Emotional Risk. But people should be aware that there are several things to consider before testing for this treacherous disease at home.

The tests help to understand how genetics affects your body, health, and how the genes result in certain diseases or conditions. Genetic testing can be difficult emotionally, not provide conclusive results and cause practical difficulties. Also, for some people, the knowledge of their increased lifetime risk might help them to plan and prioritize their lives.

My answer is that at this time, genetic testing for Alzheimer’s disease has many limitations and is beneficial for only a limited number of people. Although it is present in about 25 percent of the population, not everyone who inherits an APOE e4 develops Alzheimer’s disease, and not everyone who develops Alzheimer’s disease has an APOE e4.
