(名詞) 認知能力沒什麼衰退的老年人。亦寫成 SuperAger, super-agersuper ager

Don’t we all want to be superagers? These are the folks identified in studies as having exceptionally sharp memories in their 80s and 90s. Researchers are looking at them, trying to figure out what makes them retain bigger brain size, with accompanying attention and thinking abilities greater than most other people their age.

Our lab used functional magnetic resonance imaging to scan and compare the brains of 17 superagers with those of other people of similar age. We succeeded in identifying a set of brain regions that distinguished the two groups. These regions were thinner for regular agers, a result of age-related atrophy, but in superagers they were indistinguishable from those of young adults, seemingly untouched by the ravages of time.
