Is Alzheimers hereditary
Familial Alzheimer’s disease (FAD) is a rare form of the disease, affecting less than 10 percent of Alzheimer’s disease patients. All FAD is early-onset, meaning the disease develops before age 65. It is caused by gene mutations on chromosomes 1, 14, and 21. Even if one of these mutated genes is inherited from a parent, the person will almost always develop early-onset Alzheimer’s disease. All offspring in the same generation have a 50/50 chance of developing FAD if one of their parents had it.
