Excerpt from Alzheimer's DiseaseAt the same time, data indicate that the likelihood that a close relative (sibling, child, or parent) of an afflicted individual will develop Alzheimer's disease is low. In most cases, such an individual's risk is only slightly higher than that of someone in the general population, where the lifetime risk is below 1 percent. And, of course, many disorders have a genetic potential that is never expressed-that is, despite being at risk for a certain illness, one might go through life without ever developing any symptom of the disease.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
