As we age, the risk of developing dementia, including Alzheimer’s disease, increases. In fact, research shows that nearly half of people over 55 will develop dementia. While there’s no cure, experts agree that making certain lifestyle changes is important. These changes can greatly lower the risk of cognitive decline.
A recent study, the largest of its kind, found four simple changes that can help prevent dementia in people over 60. This study, called the POINTER trial, was funded by the Alzheimer’s Association and published in the Journal of the American Medical Association (JAMA). It involved 2,111 adults aged 60 to 79 at risk for cognitive decline. The results highlight the importance of regular physical activity, a brain-boosting diet, cognitive exercises, and social engagement to protect brain health.

Key Findings of the POINTER Study
The POINTER study followed participants for two years and provided lifestyle interventions to improve brain health.The participants were split into two groups: a structured group with accountability and guidance. And a self-guided group that received basic education and encouragement. The structured group showed significant cognitive improvement, emphasizing the value of organized interventions in boosting brain function.
The study found that four lifestyle changes were particularly effective in slowing cognitive decline and reducing the risk of dementia:
Regular Physical Exercise
Engaging in moderate to high-intensity physical exercise helps improve cardiovascular health. This is directly linked to brain health. Exercise increases blood flow to the brain and promotes the growth of new brain cells. It can delay or prevent the onset of dementia.
Adherence to the MIND Diet
The MIND diet combines the Mediterranean and DASH diets. It focuses on brain-healthy foods like leafy greens, berries, nuts, and whole grains. Following this diet can reduce the risk of Alzheimer’s and other cognitive impairments by up to 53%, especially when followed strictly.
Cognitive Challenge and Social Engagement
Keeping the brain active is key to maintaining cognitive function. The POINTER study highlighted the importance of mental stimulation, like learning new skills or brain exercises. Staying socially active also helps prevent cognitive decline, keeping the brain engaged and functioning well.
Cardiovascular Health Monitoring
Monitoring and managing cardiovascular health is important for brain health. Regular check-ups, a healthy diet, and exercise all play a role. High blood pressure, high cholesterol, and other cardiovascular issues can increase the risk of dementia, so it’s crucial to manage these factors.

Structured Intervention Makes a Difference
The structured intervention group in the POINTER study performed much better than the self-guided group. This group received in-person coaching, exercise plans, access to cognitive training apps, and regular health check-ups. As a result, they showed greater improvements in memory, attention, and overall cognitive function.
Looking Ahead: The Next Steps
The POINTER trial is not finished yet. Researchers are continuing to follow participants for four more years to track long-term effects. This follow-up study aims to provide more evidence on how these lifestyle interventions can prevent dementia. It also seeks to show how these changes can improve quality of life as we age.
In conclusion, while genetic factors contribute to dementia, adopting four simple lifestyle changes can help. These changes include physical exercise, a brain-healthy diet, cognitive challenges, and monitoring cardiovascular health. Together, they can greatly reduce the risk of developing dementia later in life.
