A high-risk gene affects the risk of cognitive decline. Some previous research has found that repeating familiar activities, even challenging ones, may not be enough to ward off cognitive decline. Researchers at the University of Texas at Dallas took a closer look at a subset of 512 people who had an increased risk of cognitive decline because they carried a version of the apolipoprotein E (APOE) gene. For carriers of the high-risk APOE gene, only computer use and social activities were associated with a decreased risk of mild cognitive impairment.
