As we age, our thoughts often turn to the quality of our golden years. We ponder the steps we can take to ensure that we live longer and maintain a high quality of life. One of the most significant concerns for Australians over 60 is the risk of dementia—a condition that can profoundly affect one's independence and well-being. A recent study has shed light on how the lifestyle choices we make at 60 can influence our risk of developing dementia decades later.


The study, conducted by the Health and Retirement Study and led by Peter Hudomiet, a PhD-level researcher and economist at the RAND Corporation, analysed over two decades of data from more than 45,000 older adults in the United States. The findings are a wake-up call for seniors to take proactive steps in their 60s to protect their brain health in their 80s and beyond.


According to the study, several factors in your 60s can serve as early predictors of dementia. Low cognitive test scores and poor general health were identified as strong indicators of future dementia risk. However, the study also highlighted some positive news: the protective effect of education, particularly having a high school diploma and the benefits of an active lifestyle.


Engaging in physical activity and mentally stimulating hobbies were associated with a lower risk of cognitive decline. On the flip side, leading a sedentary lifestyle and having few mentally stimulating interests increased the likelihood of developing dementia by age 80. Excessive alcohol use was also flagged as detrimental to brain health.

Chronic health conditions such as diabetes, obesity, and stroke by the age of 60 were strongly linked to a higher chance of dementia later in life. The study also pointed out that certain groups, including those born in Southern states and Black and Hispanic individuals, were at higher risk, potentially due to disparities in access to healthcare.

As Hudomiet points out, the good news is that addressing these disparities could help close the gaps for high-risk groups. While we can't change our genetics or turn back the clock on our age, numerous risk factors are within our control. Regular exercise, finding a hobby, staying socially active, and managing chronic conditions may all contribute to keeping the brain sharp. Additionally, limiting alcohol consumption, eating a healthy diet, and ensuring good sleep quality can all help mitigate the risk of dementia.


Kristine Yaffe, MD, a professor at the University of California at San Francisco, emphasised the importance of genetics, behaviours, and lifestyle factors in promoting brain health. She urged individuals to consider their brain health early, just as they would focus on cardiovascular health across every stage of life.

While the study doesn't conclusively prove that changing lifestyle behaviours can prevent dementia, it does show an association with a lower disease risk. The authors call for further research to explore targeted interventions for various people.

With an estimated 6.9 million Americans currently living with dementia—a number projected to double by 2060, according to the Centers for Disease Control and Prevention—the implications of this study are significant. It's a reminder that the daily habits we choose in our 60s could impact our cognitive health.

So, dear members of the Seniors Discount Club, it's time to reflect on our daily routines. Are we doing enough to stay physically and mentally active? Are we managing our health conditions effectively? Are we engaging in activities that stimulate our minds and bodies? The choices we make today could shape our tomorrow.
