Newsweek (7/22, Gander) reports, “Both our genes and our lifestyles may explain why some people maintain good memory into their 90s,” research indicated.HealthDay (7/22, Reinberg) reports that in a study involving “100 people without dementia, average age 92, who were followed for up to 14 years,” researchers sought to find out why “some people in their 90s stay sharp whether their brain harbors amyloid protein plaques – a hallmark of Alzheimer’s disease – or not.” The study revealed that “a combination of genetic luck and a healthy, fulfilling lifestyle” were probably why these people maintained cognitive resilience as nonagenarians. The findings were published online July 22 in the journal Neurology. (SOURCE: APA Headlines)
