The APOE gene has already been determined to be the biggest predictor of alzheimer’s. There are 3 variants of the gene: e2, e3, and e4. In terms of alzheimers risk, you want e2. e3 confers average risk. e4 confers really shitty alzheimers risk. You have 2 copies of this gene. So the “best in terms of alz. risk is 2 copies of e2 and the worst is 2 copies of e4. e4 has the lowest frequency and people with 2 copies are only around 2 or 3 percent of the population. But they make up a third of all alzheimers patients. People who have one copy of e4 make up another third. So people with some combination of e2 and e3 alleles are the other third and thats around 87% of the population. They passed a law declaring that it was illegal for geneticists to tell you if you had the “bad” APOE allele, because it would make you depressed and was therefore unethical. They may have changed that rule. But that just goes to show how fucking retarded our healthcare regulators have become. If you have APOE e4, don’t plan on a long retirement. Cause you’re gonna be retarded by 70 or so. There may also be an association between some viral or bacterial infections and alzheimers. Theyve found a correlation with the presence of H. Pylori in the brain. >African Americans, for example, are up to twice as likely as white Americans to develop Alzheimer’s disease. Research shows that much of this disparity is likely due to structural racism causing differences in nutrition, socioeconomic status and other social risk factors. This is a horseshit statement. People with low IQs are more likely to be diagnosed with Alz. because they become dysfunctional more quickly as the disease progresses. Intelligent people can “cope” with alzheimers dysfuction for a longer period because their brains can compensate for the loss. My mother’s neurologist basically told me point blank stupid people go down hill faster and there are a few studies on AAs and alzheimers that support this as well.
