Defining the 'Super Ager'
First coined by researchers at Northwestern University's Mesulam Center for Cognitive Neurology and Alzheimer's Disease, the term “super ager” refers to individuals over the age of 80 who possess the memory and cognitive abilities of people decades younger. It is not a single person but a research classification for a select group of the elderly population. This remarkable subset challenges common beliefs about aging, offering valuable clues into how the brain can remain resilient against typical age-related decline.
Brain Differences in Super Agers
Research using MRI scans has revealed significant differences in the brains of super agers compared to their cognitively average peers. Instead of the expected brain shrinkage, super agers exhibit a thicker cerebral cortex, particularly in areas important for memory and attention. They also show a much slower rate of annual brain volume loss—about half the rate of their peers. Furthermore, studies have found a higher density of specialized neurons, known as von Economo neurons, in the anterior cingulate cortex, a region linked to social-emotional functioning. These findings suggest that the super ager's brain is biologically more robust.
The Real-World 95-Year-Old Super Ager
While '95-year-old super ager' is a general category, individuals like Sally Froelich, a 95-year-old from New York, have gained attention for their outstanding health and cognitive abilities. A former TV host, Froelich has publicly shared her perspective on healthy aging. Her advice, often centered on lifestyle choices, provides a human face to the scientific findings. Her story, along with those of other super agers, demonstrates that certain habits and attitudes are consistent among those who age exceptionally well.
Lifestyle Traits and Habits
Across numerous studies and anecdotal accounts, several lifestyle characteristics consistently appear among super agers, including those well into their 90s. These factors are not guarantees but are strongly associated with a higher likelihood of maintaining cognitive health.
- Maintain Social Connections: Strong, positive social relationships and an active social life are a prominent theme. Super agers report warmer, higher-quality relationships, and studies suggest a link between social engagement and lower risk of dementia.
- Embrace Physical Activity: Regular physical exercise is crucial, helping to improve cardiovascular health, reduce stress, and strengthen muscles and bones. Super agers tend to be more physically independent and less sedentary than their peers.
- Pursue Mental Challenges: Continually stimulating the brain is essential for creating new neural pathways through neuroplasticity. This can involve learning a new language, playing an instrument, doing puzzles, or taking classes.
- Cultivate Resilience: Many super agers have a history of overcoming significant life challenges and exhibit a remarkable ability to bounce back from adversity. This trait is difficult to quantify but is a common thread.
Comparing Lifestyle and Biological Factors
Understanding exceptional aging involves recognizing both the genetic lottery and the power of personal choice. The following table highlights the interplay between these two dimensions.
| Factor | Biological (Nature) | Lifestyle (Nurture) |
|---|---|---|
| Brain Volume | Slower annual brain shrinkage rate, suggesting genetic predisposition. | Enhanced through physical and mental activity that promotes overall brain health. |
| Neuron Density | Higher density of specialized von Economo neurons. | Social engagement is linked to regions of the brain where these neurons are found. |
| Cognitive Function | Potential genetic markers that offer protection against decline. | Lifelong learning and mental challenges actively strengthen neural networks. |
| Resilience | Possibly innate temperament, but also a learned trait. | Shaped by past experiences and social support systems. |
Ongoing Research and the Search for Answers
Research into super aging is an active field, with multiple initiatives aiming to uncover the secrets of exceptional longevity. Researchers are not only examining the brains of living super agers through imaging but also studying the brains of deceased donors. The American Federation for Aging Research and Albert Einstein College of Medicine, for example, have recruited super agers aged 95 and older to study genetic and biological factors that slow aging and protect against diseases like Alzheimer's. The ultimate goal is to develop therapies that could help more people age with the same level of cognitive sharpness.

Conclusion: A Blueprint for Better Aging
No single 95-year-old super ager holds the exclusive key to eternal youth. Instead, these remarkable individuals represent a compelling intersection of genetic resilience and committed lifestyle choices. Their existence proves that cognitive decline is not an inevitable fate for all. The ongoing research into their unique biology and behavior provides a powerful blueprint for everyone, regardless of age, to proactively invest in their brain health. By prioritizing social connections, staying physically active, challenging our minds, and building resilience, we can all strive for a longer, more fulfilling life with enhanced cognitive vitality.
