Family history is critical in understanding possible diseases that may emerge, particularly those with a genetic link. Trump’s father, Fred Trump, died from complications of late-onset Alzheimer’s disease. That condition, which is the most common form of Alzheimer’s, emerges in people in their mid-60s or later. Trump is 70.
There is a genetic component to the disease. Risk increases when a person has a particular type of apolipoprotein E (APOE) gene on the 19th chromosome. The type of APOE gene a person has is testable. Has Dr. Bornstein, the gastroenterologist, tested for it? If not, why not? Is that why Trump has avoided seeing an internist, since they would conduct such a test?
