Cognitive decline is a natural part of aging and is often a significant source of worry for aging individuals¹. However, many people may be unaware of how early detection can help them take preventive measures to protect against cognitive decline. Reduced cognitive ability is linked to the concept of "brain age," which refers to how well your brain functions compared to what’s typical for your actual age². Brain scans produce detailed images of the brain that can identify signs of cognitive decline before noticeable symptoms appear and can help to give an indication of brain age³.

This article will focus on understanding brain age, how imaging tests can detect cognitive decline and practical steps we can take to improve and protect our memory.

How Brain Age Scans Can Help Protect Your Memory

Understanding Brain Age and Cognitive Decline

Cognitive decline is a worrisome change in brain function that naturally occurs as we age. It can significantly impact the quality of life and affect overall health, leading to issues such as memory problems, difficulty thinking clearly, and increased risk of conditions like dementia¹.

What Is Brain Age?

Brain age is a measure of how “old” the brain appears based on cognitive function and structural health as visualized using advanced imaging tests². Many factors influence our brain age, including lifestyle factors, mental health, genetics, and different diseases⁴. For example, high blood pressure is linked to cognitive decline in later life and can be influenced by lifestyle factors like diet and exercise⁵. Exercise is believed to support mental health and help slow cognitive decline, emphasizing the importance of staying physically active for maintaining a healthy brain age⁴. 

Causes of Cognitive Decline

Cognitive decline is a natural part of aging, but it is thought to be caused by other factors such as stress, poor diet, and lack of mental stimulation. Studies have shown that stress can lead directly to cognitive decline⁶. Furthermore, some foodstuffs are thought to contribute to an increased risk of mental decline⁷. This includes fast food, fried foods, and sweets⁸. Fortunately, these factors can be addressed through specific lifestyle changes, providing an opportunity for early intervention to reduce the risk of further decline.

How Brain Age Scans Work

The Technology Behind Brain Age Scans

Magnetic resonance imaging (MRI) is the primary imaging method used to take highly detailed pictures of the brain. An MRI of the brain uses powerful magnets and radio waves to create detailed images of the brain's structure³. It’s a safe, painless way to see inside the brain and detect issues like tumors, injuries, signs of disease, or cognitive decline. Shrinking in some brain areas can indicate the onset of cognitive decline⁹. Recent advances in AI are helping healthcare providers analyze brain scan images, which leads to faster and more accurate diagnoses in some cases¹⁰. While some people may have understandable reservations about AI being used in diagnosis, it’s important to note that AI is used as a tool to aid, not to replace, qualified radiologists.

Identifying Early Signs of Cognitive Decline

MRI brain scans can be used to observe a variety of different changes in brain tissue, such as the shrinking of specific areas like the hippocampus, which is important for memory and other functions¹¹. A trained radiologist can examine subtle changes in brain structure to identify potential early signs of cognitive decline. Repeated brain scans allow for monitoring brain structure over time, providing insights into brain health, tracking the progression of decline, and assessing the effectiveness of preventive strategies. By catching early signs of cognitive decline, individuals can take action to prevent progression.

Benefits of Brain Age Scans

Personalized Health Insights

Scans provide information that is specific to individuals and does not rely on a one-size-fits-all approach to preventive care. Brain scans can identify various issues affecting the brain, which may be underlying causes of cognitive decline³. This means that healthcare providers can generate patient-specific plans for prevention, which can include recommending lifestyle changes like stopping the consumption of tobacco and alcohol or focusing on improving sleep⁴. Some medications can be linked to cognitive decline, and healthcare providers may recommend reducing dosage or switching to alternatives to see if any improvements occur¹².

Proactive Memory Protection

Brain MRIs can highlight the potential for preventive strategies to help individuals protect their memory. Activities that keep the brain active and may help slow down cognitive decline. Social interactions are crucial for overall mental well-being, particularly for older adults who are more prone to social isolation¹³. Increased social interactions may help to reduce the likelihood of certain diseases like dementia¹⁴.

Reducing Anxiety About Cognitive Health

Obsessing over cognitive decline may lead to unnecessary worry when a simple solution is available to address the issue. MRI scans provide a clear view of brain structure and health, helping to alleviate concerns about cognitive issues.

Steps to Protect Your Memory

There are various actions we can take that may help to prevent or slow cognitive decline.

Engage in Cognitive Activities

Engaging in cognitive activities can help to protect memory. Consider taking up brain games and puzzles as a new hobby and enjoy these activities with friends and family. Lifelong learning is important for maintaining cognitive health, and some studies have found that individuals with extended education or who have mastered a second language may have fewer cognitive decline issues in later life^15,16.

Adopt a Brain-Healthy Lifestyle

A growing connection between physical exercise and brain activity is being discovered¹⁷. Regular exercise supports mental health and benefits sleep quality, joint strength, and overall resilience, which become increasingly important as we age. Adopting a healthier lifestyle, including a diet rich in whole foods and leafy green vegetables, promotes physical activity and supports activities that enhance cognition and overall wellness^4,8. Specific nutrients, such as omega-3 oils found in fish like salmon and tuna and seeds like chia and flaxseeds, are closely linked to brain health¹⁸.

Seek Regular Health Assessments

As we age, taking a proactive approach to our health becomes increasingly important. This can include periodic brain age scans to look for any structural changes that can indicate cognitive decline. Brain scans can bring peace of mind about your brain health and can help you and your healthcare provider prepare a long-term plan to monitor and maintain your cognitive well-being.

Summary: Stay Ahead of Cognitive Decline: How Brain Age Scans Protect Memory

Brain age scans are a powerful tool for detecting early signs of cognitive decline, enabling individuals to take proactive steps to protect their memory and overall brain health. By identifying potential issues early, these scans empower targeted lifestyle changes like healthier diets, regular exercise, and cognitive activities, all supporting long-term mental resilience. Early detection not only helps slow the effects of aging on the brain but also provides peace of mind.
