Beyond Staying Mentally Active: What Research Says About Supporting Brain Health
As life expectancy continues to increase worldwide, maintaining brain health has become an important part of healthy ageing. Many people worry about forgetfulness, slower thinking or the possibility of developing cognitive disorders later in life. Although some age-related changes in thinking are normal, researchers are increasingly discovering that everyday lifestyle choices can influence how well our brains function over time.
For many years, the advice for protecting cognitive health was relatively simple: stay mentally active. Reading books, solving crossword puzzles, playing card games or learning a new hobby were often recommended to keep the brain engaged. While these activities remain beneficial, modern research suggests that maintaining brain health requires a more comprehensive and structured approach.
Recent studies presented at the Alzheimer’s Association International Conference (AAIC), along with findings from large international clinical trials, indicate that combining cognitive training with physical activity, healthy nutrition, social engagement and cardiovascular health management may provide greater benefits than relying on general advice alone.
Although researchers continue to study exactly how these lifestyle factors influence the brain, one message is becoming increasingly clear: supporting cognitive health is not about one activity; it is about developing consistent habits that work together to keep the brain functioning at its best.
What Is Brain Health?
Brain health refers to the ability of the brain to perform its many functions effectively throughout life. These include remembering information, concentrating, learning new skills, solving problems, making decisions and adapting to new situations.
Several cognitive abilities contribute to overall brain health, including:
- Memory
- Attention
- Processing speed
- Executive function
- Language
- Reasoning
- Cognitive flexibility
- Problem-solving
These skills influence almost every aspect of daily life, from managing finances and following conversations to driving safely and maintaining independence.
While ageing naturally affects some cognitive abilities, maintaining a healthy brain is about preserving these functions for as long as possible.
Why Brain Health Matters As We Age
Growing older does not automatically mean experiencing severe memory loss or dementia. In fact, many older adults remain mentally sharp well into their later years.
However, ageing can gradually affect how efficiently the brain processes information. It may take longer to remember names, switch between tasks or learn unfamiliar information. Researchers believe that lifestyle choices including physical activity, diet, sleep, social interaction and cognitive engagement may influence how quickly or slowly these changes occur.
Because conditions such as Alzheimer’s disease and other forms of dementia affect millions of people worldwide, scientists continue to investigate practical ways to support healthy cognitive ageing. While no single intervention can completely prevent cognitive decline, combining several healthy behaviours appears to offer the greatest potential benefit.
Why “Staying Mentally Active” Is No Longer Enough
The phrase “stay mentally active” has been part of public health advice for decades. Although well intentioned, it is relatively broad and offers little guidance about which activities are most effective.
Simply keeping busy does not necessarily challenge the brain in ways that strengthen different cognitive skills. Reading the same type of material every day or repeatedly completing familiar puzzles may eventually require less mental effort as the brain becomes accustomed to those activities.
Structured cognitive training takes a different approach. Rather than providing general mental stimulation, these programmes are designed to systematically challenge specific abilities such as attention, working memory, processing speed and executive function. Many programmes gradually increase difficulty as users improve, encouraging continuous cognitive engagement.
Researchers are therefore shifting their focus from asking whether mental activity is beneficial to identifying which types of cognitive activities produce measurable improvements.
The Alzheimer’s Association International Conference (AAIC)
The Alzheimer’s Association International Conference is one of the world’s largest scientific meetings dedicated to dementia and brain health research. Every year, thousands of neurologists, psychologists, neuroscientists and healthcare professionals present new findings covering topics such as Alzheimer’s disease, cognitive ageing, prevention strategies, brain imaging and emerging treatments.
In recent years, lifestyle interventions have become an increasingly important area of discussion. Scientists are exploring how everyday habits may influence cognitive health long before symptoms of dementia appear.
One of the conference’s most widely discussed presentations highlighted results from the LATAM FINGERS study, which investigated whether a structured lifestyle programme could improve cognitive performance among older adults.
Understanding The Latam Fingers Study
The LATAM FINGERS study forms part of the Worldwide FINGERS network, an international collaboration inspired by the original Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER). Unlike studies that focus on a single intervention, LATAM FINGERS examined whether combining several healthy lifestyle strategies could produce greater cognitive benefits.
Participants followed a structured programme that included:
- Cognitive training
- Regular physical exercise
- A brain-friendly dietary pattern based on the MIND diet
- Social interaction through organised group sessions
- Monitoring of cardiovascular health, including blood pressure
Another group received similar lifestyle advice but followed it more independently without the same level of structured guidance and support. Researchers wanted to determine whether actively participating in an organised programme would be more effective than simply providing recommendations.
What Did The Study Find?
The findings were encouraging. Participants who completed the structured programme demonstrated significantly greater improvements in overall cognitive performance than those who received general advice alone.
Researchers observed improvements across several important areas of cognition, including memory, attention and executive function. Some participants also appeared to benefit more than expected, particularly those who began the programme with lower baseline cognitive scores.
Although the study does not suggest that one intervention alone is responsible for these improvements, it highlights the importance of consistency. Structured programmes may encourage people to maintain healthy habits more effectively than relying on motivation alone.
These findings also reinforce the idea that brain health is influenced by multiple lifestyle factors working together rather than by any single activity.
The Worldwide Fingers Network
Following the success of the original Finnish FINGER trial, researchers around the world launched similar studies adapted to different populations, cultures and healthcare systems.
Today, the Worldwide FINGERS network includes studies across Europe, North America, South America, Asia and Australia. While each programme reflects local dietary habits and healthcare practices, they all share the same objective: understanding whether combining healthy lifestyle interventions can help maintain cognitive function and reduce the risk of age-related cognitive decline.
The growing consistency of findings across different countries provides increasing confidence that multidomain lifestyle programmes may play an important role in supporting healthy brain ageing.
Why Structured Cognitive Training Matters
One question often raised by researchers is whether all mentally stimulating activities provide the same benefits.
To explore this, scientists have analysed numerous clinical studies comparing cognitive training, physical exercise and nutrition. While each intervention showed positive effects on cognitive health, structured cognitive training frequently demonstrated some of the strongest improvements in areas such as attention, processing speed and executive function.
Unlike casual mental activities, structured programmes are designed to progressively challenge the brain, encouraging continuous adaptation and learning. Researchers believe this targeted approach may help strengthen the neural networks involved in everyday thinking and decision-making. However, experts also emphasise that cognitive training works best when combined with other healthy lifestyle habits rather than replacing them.
The Role Of Physical Exercise In Brain Health
Regular physical activity benefits much more than the heart and muscles. It also plays an important role in maintaining brain health. Exercise increases blood flow to the brain, ensuring that brain cells receive the oxygen and nutrients they need to function effectively. It also encourages the release of proteins that support the growth and maintenance of neurons and strengthen communication between brain cells.
Research suggests that people who remain physically active throughout life often perform better on tests of memory, attention and executive function than those who lead sedentary lifestyles. Activities such as brisk walking, cycling, swimming and strength training have all been associated with better cognitive outcomes.
Current evidence indicates that combining physical exercise with cognitive training may provide greater benefits than either intervention alone, making exercise an essential part of a brain-healthy lifestyle.
Nutrition And The Mind Diet
The food we eat also influences brain health. Scientists have long studied dietary patterns to understand how nutrition affects cognition, and one eating plan that has attracted considerable attention is the MIND diet
The MIND diet combines elements of the Mediterranean and DASH diets while emphasising foods linked to better brain health. It encourages the regular consumption of:
- Green leafy vegetables
- Other colourful vegetables
- Berries
- Whole grains
- Beans and legumes
- Nuts
- Olive oil
- Fish
- Poultry
At the same time, it recommends limiting processed foods, sugary snacks, fried foods, butter and excessive amounts of red meat.
Although no diet can guarantee the prevention of cognitive decline, following a balanced, nutrient-rich eating pattern may help support healthy brain function as part of an overall healthy lifestyle.
Social Engagement And Heart Health Matter Too
Maintaining social connections is another important aspect of cognitive wellbeing. Meaningful conversations, group activities, volunteering and spending time with family and friends provide mental stimulation while also supporting emotional health.
Cardiovascular health is equally important. Conditions such as high blood pressure, diabetes, obesity and elevated cholesterol can damage blood vessels that supply the brain, increasing the risk of cognitive impairment over time.
This is one reason the lifestyle programmes used in the FINGERS studies include routine monitoring of cardiovascular health alongside cognitive and physical interventions. Looking after the heart often means looking after the brain as well.
Can Digital Cognitive Assessments Help?
Advances in technology are making it easier to monitor cognitive performance. Traditionally, comprehensive cognitive assessments have been conducted by healthcare professionals and may take an hour or more to complete.
Researchers are now evaluating shorter digital assessments that measure abilities such as memory, attention, processing speed and executive function in just a few minutes. While these tools are not designed to replace professional medical evaluations, they may help individuals monitor changes in cognitive performance over time and encourage earlier conversations with healthcare providers if concerns arise. They may also prove particularly valuable in areas where access to specialist services is limited.
What About Brain Biomarkers?
Scientists are also investigating whether lifestyle interventions can influence biological markers associated with brain health. One area of interest involves amyloid-beta proteins, which are linked to Alzheimer’s disease. Early research has explored whether structured cognitive training may affect blood biomarkers related to these proteins. Although some studies have reported promising findings, the evidence is still emerging.
It is important to recognise that changes in biomarkers do not necessarily translate into disease prevention or treatment. Larger, long-term studies are needed before researchers can fully understand how lifestyle interventions influence the biological processes involved in neurodegenerative diseases.
Practical Ways To Support Brain Health
Although research continues to evolve, several evidence-informed habits consistently appear to support cognitive wellbeing:
- Challenge your brain with structured learning or cognitive exercises.
- Engage in regular physical activity appropriate for your age and health.
- Follow a balanced eating pattern rich in vegetables, fruits, whole grains and healthy fats.
- Prioritise seven to nine hours of quality sleep each night.
- Stay socially connected through family, friends or community activities.
- Manage blood pressure, blood sugar and cholesterol.
- Reduce smoking and excessive alcohol consumption.
- Schedule regular health check-ups and discuss any persistent memory concerns with a healthcare professional.
Rather than searching for a single solution, adopting several healthy habits together is likely to provide the greatest long-term benefit.
