Researchers Develop Genetic Test That Can Predict Your Risk of Alzheimer’s Disease

July 7, 2016

(Los Angeles Times) – New research into the genetic underpinnings of Alzheimer’s disease offers fresh evidence that the devastating brain disorder may gain a foothold years before dementia sets in, and takes a key step toward earlier detection of the disease. In a study that scoured the genes of healthy young people for the presence of variants linked to Alzheimer’s disease, researchers have found that those who carried many of the telltale gene variations had a smaller hippocampus — a brain structure that is crucial to memory-formation – than did their peers with few of the genetic variations.
