A Simple Change in Thinking Style Could Make a Big Difference for Brain Health

Psychologists and brain scientists continue to study factors that may affect cognitive abilities with age, seeking to understand the relationship between psychological aspects, health, and memory.

In this context, a long-term study was conducted on thousands of people over the age of 50 to explore how mental health interacts with cognitive performance over time.

The study followed more than 10,000 men and women over 16 years, starting in 2002. Participants underwent regular health and memory assessments every two years, for a total of nine assessments.

The researchers found that people who reported higher levels of psychological well-being—such as a sense of control over their lives, independence, and satisfaction—performed better on memory tests, which included recalling ten words immediately and after a period.

Although the relationship between well-being and improved memory was limited in strength, it was statistically significant. This association remained even after accounting for the effect of depressive symptoms, suggesting an independent relationship between mental health and cognitive function.

Professor Joshua Stott, co-author of the study and professor of aging and clinical psychology at University College London, said: "This study is an important step in understanding the complex relationship between well-being and memory over time. It highlights the importance of psychological and social factors in maintaining brain health."

The researchers used questionnaires to measure quality of life, including statements such as "I can do what I want" and "I feel life is full of opportunities."

The results showed that participants with a more positive outlook were more likely to engage in healthy lifestyle habits, such as exercise, which may in turn contribute to memory support.

The researchers also noted that factors such as age, gender, and socioeconomic status may directly or indirectly influence both memory and well-being.

Although there is no clear evidence that memory decline leads to decreased well-being, the researchers haven't completely ruled this possibility out.

Commenting on the findings, Emma Taylor, director of information services at Alzheimer's Research UK, said: "Maintaining a healthy heart, mind, and social connection are important factors in preventing dementia. This study shows that happiness and life satisfaction may be linked to improved memory as we age."

Dr. Emily Willroth, co-author and assistant professor of psychological and brain sciences at Washington University in St. Louis, Missouri, said: "We hope these findings will support the development of strategies to enhance cognitive health in older adults, based on what we know about memory and well-being."

The study was published in the Journal of Aging and Mental Health.
