Genetics is defined as the study of heredity and the variation of inherited characteristics. In every one of our cells, there are 46 strands of DNA that are tightly coiled into a chromosome. Within each chromosome, it is estimated that we have between 20,000 and 25,000 genes. For the most part, genes are the same in all humans, but a small number of genes are slightly different for each individual. These small differences are what make you who you are and unique from everyone else.

Since most of our genes are the same, we are able to pick out specific segments of genetic code that correlate with a particular dysfunction or disease. These segments of genetic code can indicate the likelihood of developing a disease, such as Alzheimer’s. The most common gene associated with Alzheimer’s is apolipoprotein E (ApoE). There are three different forms of the ApoE gene: ApoE2, E3 and E4. The likelihood of developing Alzheimer’s can be influenced depending on which ApoE gene you have. On one end of the spectrum, E2 appears to be more protective, and on the other end, E4 increases the likelihood of developing Alzheimer’s.

While ApoE4 does not cause Alzheimer’s, it is associated with an increased risk of developing Alzheimer’s. This is why it is important to test early and see where you are on the spectrum. There are many therapies and lifestyle factors that can be utilized to maximize optimal health and reduce overall risk of developing Alzheimer’s or other genetic risk factors. As I tell my patients, your genetics load the gun, but it is your lifestyle that pulls the trigger. Get tested, see what genetic markers you have, correct any deficiencies you may have, clean out the inflammatory foods from your diet and maximize your health.
