But a new study warns that when young people with a family history of Alzheimer’s disease have memory lapses, it could be an early sign of something serious. That’s the concern raised by a new memory test taken by nearly 60,000 men and women between the ages of 18 and 85. The results revealed that participants between 18 and 65 who had family members with Alzheimer’s scored lower than those who did not. That included even young adults in their 20s. But, “no one should feel doomed to experience Alzheimer’s, certainly not simply because your parents or grandparents were diagnosed with the disease,” stressed study author Matt Huentelman. He is a professor of neurogenomics with TGen, a genetics research institute based in Phoenix. Lots of non-inherited factors play a role in Alzheimer’s risk, he explained. And, “there are many cases of people with family history and/or high genetic risk for Alzheimer’s who live long lives without memory problems.” But there’s no getting around the fact that roughly 75% of Alzheimer’s risk is thought to be driven by genetics, said Huentelman. And the test does suggest that a young person’s memory may be impacted by genetic risk “as many as four decades before the typical onset of Alzheimer’s… read on >
