SuperAgers: The 80-Year-Olds Whose Memory Rivals People 30 Years Younger

Ask a room full of 80-year-olds what they did to keep their memory sharp, and you'll hear kale, crosswords, and clean living. Ask the actual SuperAgers — and researchers have been asking them for 25 years — and the honest answer is messier. Many of them don't eat particularly well. Some never exercised much at all. What they consistently have isn't a routine. It's a specific kind of brain.

What actually makes someone a SuperAger

Northwestern University's SuperAging Program has followed roughly 300 people aged 80 and older since the late 1990s, when neurologist M. Marsel Mesulam coined the term. The bar to qualify is specific: a SuperAger has to score at least 9 out of 15 on a delayed word-recall test — matching the average performance of a 56- to 66-year-old. A typical 80-year-old scores around 5 out of 15.

That gap is the whole story of normal aging in miniature. Memory decline isn't universal or uniform. Some people lose half their recall by 80. A smaller group loses almost none of it.

The brain difference is real, and it's not where you'd expect

When Northwestern's team scanned and, in some cases, later examined SuperAgers' brains after death, three findings stood out. Their anterior cingulate cortex — a strip of tissue involved in decision-making and emotional regulation — was thicker than in typical older adults, and thicker even than in people 20 to 30 years younger. They carried a higher density of von Economo neurons, a specialized cell type tied to social processing. And neurons in the entorhinal cortex, a relay station that feeds information into the hippocampus, were physically larger and largely free of the tau tangles that mark Alzheimer's pathology.

None of that is something you can train at the gym.

Parvizi's patients weren't SuperAgers. But the region that switched on their will to push through a problem is the same region that stays thicker, decade after decade, in people who don't lose their memory. That's not proof of cause and effect — a stimulated patient and a naturally thick cortex are different things. It is, at minimum, a strange and specific coincidence worth sitting with.

The one behavior that does hold up

If diet and exercise don't reliably separate SuperAgers from everyone else, something else does: how they feel about getting older. In a 2002 study out of Yale, epidemiologist Becca Levy tracked 660 adults aged 50 and up for as long as 23 years, using survey data on how positively or negatively they viewed their own aging. People with more positive self-perceptions of aging lived 7.5 years longer on average — a gap that survived statistical controls for baseline health, income, and loneliness. Part of the effect, Levy's team found, ran through something they measured directly: will to live.

Attitude here isn't a vague self-help concept. It's a measured variable with a survival curve attached to it.

Train the part you can actually train

You can't will your entorhinal cortex to grow bigger neurons overnight. What you can do is keep giving your working memory a reason to stay engaged — the kind of deliberate, effortful recall that SuperAging research keeps circling back to as protective.

SuperAging isn't a formula you can copy. But it's not entirely a mystery either, and that's the more useful takeaway: the brain region tied to pushing through difficulty happens to be the one that holds up best, and the people who age well tend to expect that they will.
