Preventing cognitive decline does not mean always being able to avoid it or completely eliminating the risk of it appearing. Many factors influence cognitive health, such as age, genetics, medical history, general health status, and lifestyle. Some of these cannot be modified, but others can be worked on over time.
Therefore, when we talk about how to prevent cognitive decline in older adults, it is most appropriate to think of a global brain care strategy. It is not about a single isolated measure, but about adding sustained habits that help care for physical, mental, and social health.
In this article, we explain what can help reduce the risk of cognitive decline in older adults and what habits should be strengthened.
Can cognitive decline be prevented?
Cognitive decline can manifest with different degrees and intensities, and it does not always evolve in the same way in all people. Although it cannot always be completely prevented, there are modifiable factors that can be acted upon to care for cognitive health in the long term.
There are non-modifiable factors, such as age, genetic predisposition, or certain family history, which can influence the risk of developing cognitive problems. However, there are also factors related to lifestyle habits, cardiovascular health, diet, rest, social life, or the control of chronic diseases that can be part of a preventive strategy.
The World Health Organization has published recommendations on reducing the risk of cognitive decline and dementia, highlighting the importance of acting on modifiable factors related to health and lifestyle.
Therefore, rather than talking about absolute prevention, it is better to talk about reducing risk, caring for cognitive health, and maintaining routines that promote brain well-being over time.
How to prevent cognitive decline in older adults
To understand how to prevent cognitive decline in older adults, one must look at cognitive health broadly. The brain does not function in isolation: it depends on cardiovascular status, rest, nutrition, movement, emotional state, social life, and the control of chronic diseases.
Maintain a physically active life
Regular physical activity can contribute to cognitive health care because it promotes circulation, helps maintain autonomy, improves mood, and is part of healthy aging.
It is not always necessary to approach it as intense sport. In older people, it may be more realistic to talk about adapted movement: walking, doing gentle exercises, staying active at home, climbing stairs if possible, or following routines recommended by a professional.
The WHO recommends regular physical activity as part of its measures to reduce the risk of cognitive decline and dementia.
Take care of cardiovascular health
Cardiovascular health and brain health are closely related. Factors such as hypertension, diabetes, high cholesterol, a sedentary lifestyle, or smoking can affect the functioning of the body and also the brain.
Therefore, an important part of prevention consists of controlling chronic diseases, attending medical check-ups, and following the instructions of healthcare professionals. Managing blood pressure, glucose, cholesterol, and weight can be part of a long-term cognitive protection strategy.
The WHO also includes the control of hypertension, diabetes, cholesterol, and weight among the relevant areas for reducing the risk of cognitive decline and dementia.
Maintain a balanced diet
Diet is also part of cognitive care. A balanced, varied diet adapted to each person's needs can help maintain general health and provide important nutrients for the body's functioning.
In this regard, following healthy eating patterns, ensuring hydration, and paying attention to possible nutritional deficiencies can be part of a long-term prevention strategy. In some cases, food supplements aimed at daily cognitive care, such as FontUp®, formulated with EGCG from green tea extract, may also be appropriate, always within a global approach and accompanied by healthy habits.
To delve deeper into this point, you can consult our article on foods for memory in older adults, where we explain what to eat to care for the brain.
Sleep well and get enough rest
Rest influences concentration, mood, memory, and the ability to function during the day. Continually poor sleep can make a person feel more absent-minded, irritable, or with less mental energy.
In older people, taking care of rest involves maintaining regular schedules, reviewing nighttime habits, avoiding stimulants if they affect sleep, and consulting if there are persistent problems such as insomnia, frequent awakenings, or daytime sleepiness.
The goal is not only to sleep more but to improve the quality of rest and detect possible problems that may be affecting cognitive performance.
Maintain social relationships
Social life is also part of cognitive care. Conversing, participating in activities, maintaining family or community ties, and avoiding isolation can help maintain routines, motivation, and mental stimulation.
It's not about having an intense social calendar, but about maintaining contact with other people and participating, as much as possible, in meaningful activities. Loneliness or isolation can affect emotional well-being and, in some cases, influence cognitive health.
Stimulate the mind in daily life
Keeping the mind active can contribute to cognitive care, especially when activities are varied, adapted, and enjoyable. Reading, conversing, learning something new, listening to music, doing hobbies, cooking following a recipe, or participating in cultural activities can stimulate different abilities.
Here, it is important to avoid understanding cognitive stimulation as an obligation or as a closed list of exercises. The important thing is that the person engages in activities that they find motivating and that pose a certain challenge, without generating frustration.
Review hearing, vision, and emotional state
Hearing, vision, and emotional state can also influence cognitive performance. A person who hears poorly, sees with difficulty, or feels depressed may seem more absent-minded, less participative, or with less capacity for attention.
Therefore, it is important to review these aspects as part of prevention. Correcting auditory or visual problems, addressing symptoms of depression or anxiety, and taking care of emotional well-being can help maintain a better quality of life.
Avoid tobacco and moderate alcohol consumption
Avoiding tobacco and moderating or avoiding alcohol consumption is also part of brain care. These habits can affect cardiovascular health, rest, overall health, and consequently, cognitive function.
The WHO includes not smoking and avoiding harmful alcohol consumption among its recommendations for reducing the risk of cognitive decline and dementia.
Consult a healthcare professional when necessary
Although lifestyle habits can help care for cognitive health, prevention should not replace professional follow-up when there are doubts, previous illnesses, or persistent changes in memory, attention, language, or orientation.
Consulting a healthcare professional allows for individual assessment of each case, review of possible risk factors, detection of treatable causes, and adaptation of recommendations to the age, health status, and needs of each person.
