Exploring the secrets of super-aging: a UK Biobank study on brain health and cognitive function

Communities across the globe are faced with a rapidly aging society, where age is the main risk factor for cognitive decline and development of Alzheimer's and related diseases. Despite extensive research, there have been no successful treatments yet. A rare group of individuals called super-agers have been noted to thrive with their exceptional ability to maintain a healthy brain and normal cognitive function even in old age. Studying their traits, lifestyles, and environments may provide valuable insight. This study used a data-driven approach to identify potential super-agers among 7121 UK Biobank participants and found that these individuals have the highest total brain volume, best cognitive performance, and lowest functional connectivity. The researchers suggest a novel hypothesis that these super-agers possess enhanced neural processing efficiency that increases with age and introduce a definition of the neural efficiency index. Furthermore, several other types of aging were identified and significant structural-functional differences were observed between them, highlighting the benefit of research efforts in personalized medicine and precision nutrition.

Automated summary

Communities around the world face the challenge of an aging population, where age is the primary risk factor for cognitive decline and diseases like Alzheimer's. However, a group of exceptional individuals known as super-agers have been found to maintain a healthy brain and cognitive function in old age. This study identified potential super-agers among UK Biobank participants and found that they have larger brain volume, better cognitive abilities, and less functional connectivity.
