Highlights:
- Regular physical activity, a balanced diet and adequate sleep can support brain health
- Managing blood pressure, diabetes, cholesterol and hearing problems is an important part of protecting cognitive health
- Learning new skills, staying socially connected and avoiding tobacco can contribute to healthier aging
Brain health affects how we think, learn, remember, communicate, move and respond to emotions. Although some changes in brain function can occur with age, cognitive decline is not inevitable for everyone. The World Health Organization (WHO) updated its guidance on reducing cognitive decline and dementia in 2026, emphasising healthy behaviours, management of medical conditions and a life-course approach to brain health (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
While no single habit can guarantee protection against dementia, a combination of healthy lifestyle choices and appropriate medical care may help support cognitive function and reduce the risk of cognitive decline.

What is Brain Health?
Brain health refers to how well the brain performs across several areas, including thinking, memory, learning, movement, emotional responses and sensory processing.
Cognitive health is one part of overall brain health. It involves the ability to think clearly, acquire new information, remember experiences and perform everyday tasks.
Brain function can be influenced by several factors, including age, genetics, sleep, physical activity, nutrition, mental health, medical conditions and environmental exposures. Some factors cannot be changed, but many can be managed to support better health over time (Cognitive Health and Older Adults“,”https://www.nia.nih.gov/health/brain-health/cognitive-health-and-older-adults”]”>2✔).

How Can You Take Care of Your Brain Health?
Brain Health: Myth or Fact?
Educational quiz only. Healthy habits may support cognitive health
but cannot guarantee dementia prevention.
1. Stay Physically Active
Regular physical activity benefits overall health and may help preserve cognitive function. Exercise supports cardiovascular health, helps manage blood pressure and blood sugar, and can contribute to better mood and sleep.
Walking, cycling, swimming, dancing and other activities suited to your ability can help you remain active. Strength training and balance exercises can also support mobility and reduce the risk of falls.
The WHO recommends physical activity as an intervention to help reduce the risk of cognitive decline in adults with normal cognition (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
You do not necessarily need an elaborate workout routine. Consistency matters, and people who have chronic illnesses or mobility limitations can discuss suitable activity levels with their healthcare professional.
2. Eat a Balanced, Nutrient-Rich Diet
The brain requires a steady supply of energy and essential nutrients to function properly. A varied, balanced diet can support brain health as part of an overall healthy lifestyle.
Include a range of vegetables, fruits, whole grains, pulses, nuts, seeds and appropriate protein sources. Fish, where consumed, can provide protein and omega-3 fatty acids. Healthy dietary patterns also help support cardiovascular and metabolic health.
The WHO’s 2026 guidance states that a healthy, balanced dietary pattern may be recommended to adults with normal cognition or mild cognitive impairment as part of efforts to reduce cognitive decline and dementia risk (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
However, no single food can guarantee better memory or prevent dementia. A varied diet is generally more useful than relying on a so-called brain-boosting food or supplement.
3. Get Enough Quality Sleep
Sleep supports several brain functions, including attention, learning and memory. Insufficient or disrupted sleep can affect concentration, reaction time and the ability to process information during the day.
Adults generally benefit from around seven to nine hours of sleep each night, although individual requirements vary.
To support better sleep:
- Maintain a reasonably consistent sleep and wake schedule.
- Reduce caffeine intake later in the day if it affects your sleep.
- Keep your bedroom comfortable, quiet and dark.
- Limit activities that delay bedtime and establish a relaxing bedtime routine.
- Seek medical advice for persistent insomnia, loud snoring or suspected sleep apnoea.
Sleep problems can have several causes. Persistent daytime sleepiness or ongoing difficulty sleeping deserves attention rather than being dismissed as a normal part of aging (Cognitive Health and Older Adults“,”https://www.nia.nih.gov/health/brain-health/cognitive-health-and-older-adults”]”>2✔).
4. Keep Your Mind Active
Reading, learning a language, playing an instrument, solving puzzles and acquiring new skills can provide mental stimulation.
The aim is to engage with activities that are interesting and appropriately challenging. You could learn a new recipe, practise a musical skill, take up a craft or explore a subject you have always wanted to understand.
Cognitive stimulation and engagement are included in the WHO’s updated recommendations for reducing the risk of cognitive decline and dementia in adults with normal cognition or mild cognitive impairment (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
However, enjoying brain-training games does not mean they are proven to prevent dementia. Evidence about the benefits of specific commercial brain-training programmes remains limited, and improvements on a particular task may not translate into better everyday cognitive function.
5. Stay Socially Connected
Conversations, shared activities and meaningful relationships can provide emotional support and opportunities for mental engagement.
Regular contact with family, friends and community groups may help reduce social isolation. Activities such as volunteering, joining a group, participating in community events or speaking with a friend can help people remain connected.
Social engagement is among the factors addressed in current dementia risk-reduction guidance (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
Social connection is not a substitute for treatment when someone experiences depression, anxiety or other mental health concerns. Persistent loneliness or emotional distress may warrant additional support.
6. Manage Blood Pressure, Blood Sugar and Cholesterol
Brain health is closely linked to cardiovascular and metabolic health. High blood pressure, diabetes and abnormal cholesterol levels can contribute to vascular damage, including damage affecting the brain.
Over time, vascular problems can increase the risk of stroke and may contribute to cognitive impairment and dementia.
Steps that can help include:
- Checking blood pressure as recommended.
- Monitoring blood glucose and managing diabetes with appropriate medical care.
- Checking cholesterol when advised and following an appropriate treatment plan.
- Taking prescribed medicines consistently and attending follow-up appointments.
- Seeking medical advice about weight management and other relevant health risks.
The 2024 Lancet Commission report identified several potentially modifiable dementia risk factors, including hypertension, diabetes, high LDL cholesterol, physical inactivity, hearing loss and smoking (Livingston G, Huntley J, Liu K et al.Dementia prevention, intervention, and care: 2024 report of the Lancet standing CommissionThe Lancet, 2024; 404, 572-628.“,”https://doi.org/10.1016/S0140-6736(24)01296-0″]”>3✔).
Managing these conditions benefits overall health and may contribute to reducing the risk of cognitive decline. It does not eliminate the possibility of developing dementia.
7. Protect Your Hearing and Vision
Hearing and vision affect how people communicate, interact with their surroundings and participate in everyday activities.
Untreated hearing loss can make conversations more difficult and contribute to social isolation. Vision problems can also limit mobility, independence and participation in activities.
Arrange hearing or vision assessments when appropriate, use prescribed corrective devices and seek professional advice if you notice changes.
The 2024 Lancet Commission included hearing loss and untreated vision loss among potentially modifiable factors relevant to dementia risk (Livingston G, Huntley J, Liu K et al.Dementia prevention, intervention, and care: 2024 report of the Lancet standing CommissionThe Lancet, 2024; 404, 572-628.“,”https://doi.org/10.1016/S0140-6736(24)01296-0″]”>3✔). Addressing these problems may support communication, daily functioning and quality of life, although it cannot guarantee dementia prevention.
8. Avoid Tobacco and Limit Alcohol
Smoking harms blood vessels and increases the risk of cardiovascular disease and stroke, which can affect brain health. Stopping tobacco use is an important step towards protecting overall health.
Excessive alcohol consumption is also associated with several health risks, including neurological and cardiovascular problems. Reducing harmful alcohol use is part of the WHO’s dementia risk-reduction guidance (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
If you smoke, seek support for quitting. If you drink alcohol, consider reducing consumption and discuss concerns with a healthcare professional, particularly if you have a medical condition or take medicines that may interact with alcohol.

Do Brain Health Supplements Really Work?
Supplements marketed for memory, focus or brain health often contain vitamins, minerals, herbal ingredients or omega-3 fatty acids. However, a product being labelled as a brain supplement does not mean it has been shown to prevent cognitive decline.
The WHO’s 2026 guidance does not recommend vitamin B supplements, vitamin E, omega-3 polyunsaturated fatty acids or multivitamin and mineral supplements specifically to reduce cognitive decline or dementia risk in the absence of a diagnosed deficiency, because evidence of benefit is insufficient to outweigh potential harms (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔).
This does not mean that supplements are never appropriate. A person with a confirmed nutritional deficiency or a condition affecting nutrient absorption may require treatment under medical guidance.
Before taking supplements for memory or concentration, consider whether there is an underlying cause for the concern. Unexplained cognitive symptoms may require medical assessment rather than self-treatment.
Can You Prevent Memory Loss as You Age?
Some changes in memory and processing speed can occur with age. However, significant or progressive cognitive difficulties should not automatically be attributed to getting older.
The evidence supports addressing modifiable risk factors, maintaining physical activity, following a balanced diet, managing medical conditions and staying socially and mentally engaged as part of healthy aging (Risk reduction of cognitive decline and dementia: WHO guidelines, second edition“,”https://www.who.int/publications/i/item/9789240123557″]”>1✔, Livingston G, Huntley J, Liu K et al.Dementia prevention, intervention, and care: 2024 report of the Lancet standing CommissionThe Lancet, 2024; 404, 572-628.“,”https://doi.org/10.1016/S0140-6736(24)01296-0″]”>3✔).
These steps may help reduce risk, but they cannot guarantee that memory loss or dementia will be prevented. Age, genetics and other factors also influence brain health.
It is also important to distinguish occasional forgetfulness from persistent changes that interfere with everyday life. Repeatedly forgetting recent conversations, becoming disoriented in familiar places, struggling with familiar tasks or experiencing noticeable changes in judgement may warrant medical assessment.
Some causes of memory difficulties are treatable, including certain medication effects, sleep disorders, depression and nutritional deficiencies. Early evaluation can help identify appropriate care.
When Should You Seek Medical Advice?
Consult a healthcare professional if memory problems, confusion or changes in thinking persist, worsen or begin to affect daily activities.
Sudden confusion, difficulty speaking, facial drooping, weakness on one side of the body or sudden loss of balance may indicate a stroke or another medical emergency. Seek emergency medical care immediately.
What Is the Best Way to Maintain Brain Health?
There is no single food, exercise or supplement that can protect every aspect of brain function. Brain health is supported by a combination of healthy behaviours, appropriate medical care and attention to changing needs throughout life.
Regular movement, adequate sleep, balanced nutrition, mental stimulation, social connection and management of cardiovascular risk factors are practical starting points.
Taking care of your brain is a lifelong process. Small, consistent choices can support overall health and may help reduce the risk of cognitive decline, even though no lifestyle approach can guarantee protection against dementia.
