As the global population ages, understanding the variability in cognitive aging becomes increasingly important. Why do some individuals remain cognitively sharp while others experience significant decline? This question has been central to my doctoral research. Recent studies introduce the “orchid and dandelion” phenomenon to cognitive aging, suggesting that some people, like orchids, are highly sensitive to their environment, thriving or deteriorating based on external conditions. Others, like dandelions, show resilience and maintain cognitive performance regardless of their surroundings. This framework could reshape our approach to cognitive health interventions in older adults, leading to more personalized and effective strategies to mitigate…
