Emily Rogalski, a neurology professor at the University of Chicago and a leading expert on 'SuperAgers,' shares insights into the remarkable individuals over 80 who exhibit memory capabilities similar to those in their 50s. She reveals how these 'SuperAgers' defy aging stereotypes through unique cognitive traits and lifestyle choices. The discussion touches on the myths of brain aging, the impact of social connections, and the importance of engaging activities that contribute to maintaining mental health and cognitive function well into old age.
SuperAgers, individuals over 80, exhibit brain structures that show slower atrophy rates, enabling them to maintain exceptional memory performance.
Lifestyle factors, such as social engagement and lifelong learning, play a crucial role in the cognitive resilience seen in SuperAgers.
Deep dives
Understanding Super Agers
Super agers are individuals over 80 years old who exhibit memory performance comparable to people in their 50s and 60s. Research is focusing on these extraordinary individuals to uncover the factors contributing to their robust mental health as they age. By contrasting super agers with those experiencing cognitive decline, researchers hope to identify protective elements that may contribute to successful aging. This shift in perspective encourages a more positive conversation about aging, highlighting the potential for maintaining cognitive abilities rather than only addressing cognitive decline.
Biological Features of Super Agers
Unique biological characteristics distinguish super agers from average older adults, particularly in brain structure. Super agers often retain cortical thickness similar to much younger adults, indicating slower rates of brain atrophy. Studies have shown that areas of the brain vital for attention and memory, such as the anterior cingulate, are thicker in super agers compared to their peers. Additionally, super agers have a higher abundance of certain neurons associated with social behavior, suggesting a complex interplay between biology and social engagement in maintaining cognitive health.
Lifestyle Factors and Social Engagement
While genetics play a significant role, lifestyle factors such as social engagement and new learning activities are critical for super agers. Research indicates that stronger social connections correlate with improved cognitive health, emphasizing the need to combat social isolation. Interestingly, there is no single diet or exercise routine that defines super agers, as their approaches vary widely. The focus should be on maintaining enjoyable and challenging activities that stimulate the brain, as these experiences seem to contribute to cognitive resilience and longevity.
https://haarc.center.uchicago.edu/We used to think aging inevitably led to memory loss, but a small group of people—known as SuperAgers—are defying the odds. These individuals, all over 80, have the memory performance of someone in the 50s. The question is: how?
One of the leading experts studying SuperAgers is University of Chicago neurologist Emily Rogalski. She explores the fascinating science behind SuperAgers—uncovering what makes their physical brains different and how their lifestyle choices could be the key to a having a sharper, healthier brain well into old age.
