Anyone looking to reduce their risk of dementia will find many promises and even more individual tips for everyday life. A more helpful approach is to take a systematic look at modifiable risk factors, appropriate medical care, and habits that can be sustained over the long term. This does not guarantee that you will never develop dementia. Prevention is meant to open up possibilities for action, not to assign blame.
The World Health Organization updated its guidelines on reducing the risk of cognitive decline and dementia in July 2026. The guidelines combine health-promoting habits with the treatment of relevant medical conditions and consideration of environmental factors. This broad approach makes more sense than searching for a single food, exercise, or product that supposedly offers comprehensive protection. [1]
Reducing the Risk of Dementia: What the Term Actually Means
Dementia refers to impairments in memory, thinking, and daily living skills that can result from various brain disorders. It is not necessarily a part of the aging process. In addition to diseases and lifestyle habits, the WHO also cites social conditions and environmental factors as contributing factors. This means that the risk is only partially within an individual’s control. [2]
Risk reduction changes probabilities. It does not allow for a definitive prediction for any individual. It also follows that if someone becomes ill despite maintaining healthy habits, this does not indicate personal failure. Similarly, a single risk factor does not mean that the disease will inevitably occur. This distinction helps people follow recommendations with confidence while maintaining realistic expectations.
For everyday life, therefore, there’s a question that’s more helpful than „Am I doing everything right?“: What one or two changes make medical sense for me and are practically feasible? For one person, the answer might be better blood pressure management; for another, it might be a hearing evaluation or support to help them participate in shared activities again.
Adapt exercise to your own abilities
According to the WHO, regular physical activity supports physical and mental health and can reduce the risk of several chronic diseases. For adults, the WHO generally recommends at least 150 to 300 minutes of moderate-intensity physical activity per week, as well as muscle-strengthening activities. For older adults, exercises to improve balance and functional abilities should also be included. The exercise regimen should be tailored to the individual’s health status and physical capacity. [3]
A general guideline is not a call to immediately start a comprehensive exercise program. First, consider what kinds of physical activity are already part of your daily routine and which forms are accessible to you. If you have any medical conditions, pain, a risk of falling, or significant physical limitations, discuss suitable options with a specialist. Support with transportation or finding the right group can also be crucial.
Be specific about the next step: schedule a consultation, review a suitable program, or walk a familiar route together. Then check to see if the scope and process are a good fit. It’s more helpful to build a sustainable habit than to choose a plan that fails right from the start due to organizational constraints.
Take Vascular Health and Blood Pressure Seriously
The SPRINT-MIND study found that mild cognitive impairment occurred less frequently in the group receiving more intensive blood pressure treatment. For dementia, the difference was not statistically significant in the initial analysis. In addition, the more intensive treatment was associated with potential side effects. The study supports the importance of well-managed blood pressure control; it does not justify a uniform target value or a blanket change in medication for everyone. [4]
At your next preventive care appointment, you can ask which blood pressure checks are recommended and how the readings should be interpreted. If you take your blood pressure at home, ask for a demonstration of the procedure and clarify when you should consult your doctor. A single, isolated reading is less helpful than a series of readings that can be tracked and interpreted together.
Be sure to include any pre-existing medical conditions in your planning. It is crucial to discuss scheduled checkups, treatment, and potential side effects. A brain health strategy must take your overall health into account. It should not lead you to take medication in higher doses or more frequently than prescribed out of fear of dementia.
Hearing and participation go hand in hand
The ACHIEVE study examined hearing aid use among older adults with untreated hearing loss. Across the entire study group, there was no significant difference in the primary cognitive outcome after three years. However, in a pre-specified analysis, the effects differed between groups with varying baseline risk. The results support a nuanced approach rather than the claim that hearing aids prevent dementia in everyone. [5]
Regardless of an individual risk assessment, it’s worth addressing specific hearing problems. If conversations become difficult, note the situations in which this occurs: in groups, on the phone, or when there is background noise. These examples make the evaluation easier. If a hearing aid is recommended, be sure to ask about the adjustment period, fitting, and follow-up appointments.
When engaging in group activities, practical arrangements are helpful. Ask which seat is most suitable and whether people should speak one after another. Avoid making arrangements without consulting the person involved. Planning should take their wishes and capabilities into account, rather than being based solely on an abstract prevention goal.
Making Nutrition a Reliable Foundation
The WHO describes a varied diet that includes vegetables, fruits, legumes, and whole grains as part of a healthy diet. This also includes ensuring an adequate intake of nutrients and limiting the consumption of excessive amounts of salt, free sugars, and certain fats. The exact composition depends, among other things, on one’s life situation, available foods, and health needs. [6]
So start by assessing what makes a healthy diet feasible in everyday life. Are shopping and meal preparation manageable? Are there any difficulties with chewing, swallowing, or eating with others? Is there enough support if someone lives alone? A good plan takes these factors into account rather than simply providing a list of recommended foods.
The updated WHO recommendations advise against using vitamin B or vitamin E supplements, omega-3 supplements, or multivitamin and mineral combinations solely for the prevention of dementia without a diagnosed deficiency. Treating a confirmed deficiency is a separate matter and should be discussed on an individual basis. A prevention claim on the packaging does not replace this assessment. [1]
Fostering intellectual interests and social connections
The WHO includes cognitive stimulation, cognitive training, and social activities in its risk-reduction recommendations. These recommendations are intended for people with normal cognitive function or mild cognitive impairment. This does not imply any guarantee regarding a specific app, puzzle book, or a set daily exercise duration. [1]
Choose something that has meaning beyond the purpose of the exercise: a discussion group, making music together, a class, or exploring a familiar area of interest. Small practical details are often crucial to making this work. Is the location accessible? Is the information easy to read? Is the pace appropriate? Will someone accompany you to the first session?
Staying in touch doesn’t have to be a big undertaking either. A set appointment or a regularly scheduled phone call is often easier to plan than a general resolution to socialize more. If a plan doesn’t work out, it can be adjusted. The value of an encounter doesn’t depend on whether one’s memory can be tested afterward.
Take sleep and rest into account
Adequate sleep time, regular routines, and a suitable sleep environment are among the NHLBI’s recommendations for healthy sleep habits. These guidelines support overall health; they do not prove that any single sleep practice prevents dementia. Persistent sleep problems should be discussed with a healthcare professional rather than simply trying to solve them through a series of self-experiments. [9]
When preparing for your appointment, note whether the main issue is difficulty falling asleep, frequent awakenings, or significant daytime sleepiness. Information from a trusted person can also be helpful, provided you agree to it. Together, you can determine which observations are relevant and whether further testing is necessary.
Have memory changes evaluated early on
The Austrian health portal recommends that individuals experiencing persistent problems with memory, orientation, or other cognitive abilities first consult their family doctor or a primary care facility. The evaluation includes a discussion about the onset and progression of symptoms, physical examinations, and, depending on the situation, tests or laboratory results. A specialist or a specialized memory clinic can then address any further questions. [7]
Provide specific examples: Which familiar tasks have become more difficult, and what changes have you noticed—and since when? If you would like support, discuss in advance what observations this support should complement. A respectful conversation allows the person involved to express their own perspective. The assessment is intended to provide guidance and facilitate appropriate support.
Even after a diagnosis, support remains important
According to the Austrian health portal, Alzheimer's disease is currently incurable. Nevertheless, treatment aims to achieve important goals: slowing the progression of the disease and maintaining independence and quality of life for as long as possible. The specific medical and supportive measures that are appropriate depend on the exact diagnosis, the stage of the disease, and the individual's situation. [8]
Prevention and care should therefore not be pitted against one another. People who are already experiencing symptoms do not need to adopt a stricter lifestyle right away; rather, they need appropriate evaluation and counseling. Work together to determine upcoming appointments, accessible points of contact, and practical assistance. Family members may also need support and relief in this process.
A manageable personal plan
Choose one medical and one everyday next step. For example, you can schedule a blood pressure or hearing checkup and, at the same time, plan a regular social activity. Make a note of what help you’ll need to do this. Check back later to see if the plan was actually feasible.
