Close friends linked to a sharper memory [medicalxpress.com]

Maintaining positive, warm and trusting friendships might be the key to a slower decline in memory and cognitive functioning, according to a new Northwestern Medicine study.

SuperAgers—who are 80 years of age and older who have cognitive ability at least as good as people in their 50s or 60s—reported having more satisfying, high-quality relationships compared to their cognitively average, same-age peers, the study reports.

Previous SuperAger research at the Cognitive Neurology and Alzheimer's Disease Center (CNADC) at Northwestern University Feinberg School of Medicine has focused on the biological differences in SuperAgers, such as discovering that the cortex in their brain is actually larger than their cognitively average, same-age peers. This study, published Oct. 23 in the journal PLOS ONE, was the first to examine the social side of SuperAgers.
