Title: Spanish Researchers Discover Factors Contributing to “SuperAgers”
Spanish researchers have made significant findings that shed light on the lifestyle choices that may contribute to the phenomenon of “SuperAgers” – individuals in their 80s who possess remarkably sharp cognitive abilities comparable to those 30 years younger. The study, conducted by a team of scientists from Spain, reveals several key factors that differentiate SuperAgers from typical older adults.
The research, which involved extensive brain scans, blood tests, and cognitive assessments, spanned over a four-year period. The analysis showed that SuperAgers exhibited more grey matter in the areas of the brain associated with movement, indicating a potential correlation between cognitive health and physical agility. Surprisingly, although physical activity levels were similar for both groups, it was observed that SuperAgers might engage in more demanding activities such as gardening or stair climbing.
The study also revealed that SuperAgers experienced lower levels of depression and anxiety compared to their counterparts, both of which are known risk factors for developing dementia. Additionally, SuperAgers reported being more active during their midlife, satisfied with their sleep patterns, and independent in their daily lives. These lifestyle characteristics may, in turn, contribute to their exceptional brain health and cognitive function.
Another vital finding from the research showed that SuperAgers had a thicker cortex, responsible for vital cognitive functions such as thinking, decision making, and memory. This thicker cortex is considered a key characteristic of individuals who maintain exceptional cognitive abilities in their later years. Moreover, SuperAgers were found to have positive outlooks, continuously challenged their brains, remained engaged in work even in their 80s, and maintained active social lives.
Interestingly, genetic factors did not appear to significantly influence the SuperAgers phenomenon. Despite having similar levels of APOE genes, including the APOE4 variant, a significant risk factor for Alzheimer’s disease, as the typically-aging group, SuperAgers showcased greater grey matter volume in regions of the brain linked to cognitive functioning, spatial memory, and overall memory.
These groundbreaking discoveries suggest that SuperAgers possess additional protective factors that help guard against the risk of dementia. These potential mitigating factors could be attributed to genetic or lifestyle elements that are yet to be fully understood.
The Spanish researchers’ findings offer valuable insights into the lifestyle choices and characteristics that may contribute to maintaining optimal cognitive health in advanced age. Understanding these factors may assist in future research and interventions aimed at promoting healthy brain aging for the general population.
