Researchers Identify Factors Linked With Healthy Memory in Older Adults

A study by University of Alberta (U of A) neuroscientists published in the Journal of Alzheimer's Disease identified different factors for maintaining healthy memory and avoiding memory decline for people 55 and older. Medical Xpress reports that the researchers used machine learning to analyze data from a long-term study. They found adults with healthy memory were more likely to be female, educated, and enjoy more social activities. They also were more likely to engage in new cognitive activities, like using a computer or learning a second language. Healthy memory was associated with lower heart rate, higher body mass index, more self-maintenance activities, and living companions in people 55 to 75, while adults older than 75 exhibited faster gait and fewer depressive symptoms. Persons with declining memory tended to pursue fewer new cognitive activities. "These modifiable risk and protective factors may be converted to potential intervention targets for the dual purpose of promoting healthy memory aging or preventing or delaying accelerated decline, impairment, and perhaps dementia," suggested U of A's Peggy McFall.
