Memory naturally fades with age, but that doesn’t always mean dementia is setting in. Many older adults experience minor lapses, known as senescent forgetfulness, which may remain stable or even improve. Understanding what drives these changes—and how to slow them—can help preserve cognitive health and overall well-being.
New research from Capital Medical University sheds light on this issue.
A long-term study, published in the British Medical Journal, reveals six key lifestyle habits that can slow memory decline. These habits prove beneficial even for those genetically predisposed to dementia, offering hope for maintaining brain function later in life.
Tracking over 29,000 adults aged 60 and older, the study spanned a decade from 2009 to 2019. Researchers analyzed participants across China, identifying behaviors that significantly impact memory retention. Their findings highlight practical steps that could help aging populations stay sharp longer.
Participants were grouped based on their adherence to six healthy habits:
Participants’ lifestyles were categorized as favorable (four to six healthy habits), average (two to three), or unfavorable (zero to one).

Memory tests and genetic screenings revealed a compelling link between these habits and cognitive health. Individuals in the favorable group showed a slower rate of memory decline over the ten years, regardless of whether they carried the APOEε4 gene—a major risk factor for Alzheimer’s disease.
This finding underscores the potential of lifestyle changes to combat genetic risks. “Even those with the APOEε4 gene benefited from healthier habits,” the study notes, offering hope to millions who carry this genetic marker.
While past research has emphasized the importance of physical and mental exercise, this study highlights the pivotal role of a balanced diet. Consuming a variety of nutrient-rich foods had the most significant impact on memory preservation.
Cognitive activities and social interaction also emerged as key factors, demonstrating that mental stimulation and emotional well-being are vital for cognitive longevity.
Carol Brayne, a public health expert at the University of Cambridge, praised the study for broadening the understanding of lifestyle impacts on cognitive health, particularly since it was conducted outside Western, high-income countries. She emphasized that “engaging in various health-related activities, even in later life, positively influences cognitive function and memory.”
However, the study’s reliance on self-reported data introduces potential inaccuracies. Participants may have already been predisposed to healthier lifestyles, which could have influenced the results. Despite these limitations, the findings align with a growing body of evidence that healthy living promotes cognitive resilience.
The study provides an encouraging message: lifestyle changes can reverse or stabilize memory decline, reducing the risk of progression to dementia. According to the researchers, these findings offer an “optimistic outlook” for preserving memory and cognitive health.
Experts agree that it’s never too late to adopt healthier habits. Even small changes in physical activity, diet, and social engagement can yield significant benefits.
This comprehensive approach to brain health empowers individuals to take proactive steps toward aging gracefully while maintaining cognitive function.
