Your abilities, health and interests should be taken into consideration when making brain-healthy choices. If you have questions, speak to your doctor or healthcare provider, or get in touch with your local Society for some recommendations.

Why brain health is so important

While there are some risk factors you cannot control for dementia, such as age and genetics, reducing the effects of risk factors that can be controlled is possible.

By following these tips and strategies, you're not only reducing your risk of dementia, you're also:

  • Looking after your long-term brain health,
  • Reducing your risk of other cognitive and chronic diseases, and
  • Protecting your overall health

Be physically active

People who exercise regularly are less likely to develop heart disease, stroke and diabetes – all risks associated with dementia.

Physical activity also pumps blood to the brain, which nourishes the cells with nutrients and oxygen. As well, regular exercise helps to reduce stress and improve your mood.

Being physically active can reduce these risk factors for dementia:

  • Depression
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Lack of physical activity

Five tips for being physically active

  1. Start where you can and set reasonable goals. If you feel you have little opportunity to exercise, start by adding a bit of physical activity into your daily routine. Choose a brisk walk or roll to the store rather than driving the car, or take the stairs instead of the escalator or elevator for one or two floors.
  2. Think of it as "activity", not "exercise." Choose activities and sports that you enjoy, and physical activity won't seem like a chore or task to tick off.
  3. Once you get going, aim for at least 150 minutes of moderate-to-vigorous physical activity per week. Moderate activities could be walking a dog or going for a bicycle ride, while vigorous activities include swimming or going for a run. If you have reduced mobility, try activities that can help you maintain your balance and prevent falls, such as gentle yoga or tai chi.
  4. Consider aerobic activities. Aerobic activities, such as walking, swimming, hiking and dancing, can help maintain general fitness. Many experts recommend walking as one of the safest and most effective forms of aerobic exercise.
  5. Plan out your physical activity with someone you know. That way, you are more likely to keep active while you also gain the brain-healthy benefits of social interaction.

Be socially active

Staying connected socially helps you stay connected mentally. Research shows that regularly interacting with others may help reduce your risk of developing dementia.

Having an active social life also can reduce your stress, brighten your mood and keep your relationships strong.

Being socially active can reduce these risk factors for dementia

  • Depression
  • Social isolation

Five tips for being socially active

  1. Make the most of your daily opportunities to socialize. Chat with your taxi driver or store clerk; make conversation in the elevator.
  2. Practice a random act of kindness. It could be as small as smiling at someone else passing by – paying your happiness forward will not only brighten someone else's day, but yours as well!
  3. Find time to volunteer. Whether it's participating in service clubs or joining a hobby group, you'll find that there are many healthy benefits to volunteering. It can build self-esteem and confidence, and it can expand your network of social support.
  4. Combine social interaction with an activity. It could be a physical activity like walking together or a fitness class, or it could be something like a book club or a play. Ask someone to try a brain-challenging game together. Enjoy yourself while you positively impact your brain health.
  5. Maintain old friendships and make new ones. Stay social through work, volunteer activities, travel, hobbies, family and friends. Be open to new experiences – accept invitations and extend a few of your own. Keep up your old and new friendships through talking on the phone, chatting online via email or social media, or even writing a letter.

Follow a healthy diet that you enjoy

We know that healthy eating can reduce the risk of heart disease, stroke and diabetes. These conditions are risk factors for dementia.

Healthy dietary choices not only improve your general health, in the long-term nutritious food helps maintain brain function and fight cognitive decline.

Eating healthily can reduce these risk factors for dementia:

  • Diabetes
  • High alcohol consumption
  • High cholesterol

Five tips for eating healthily

  1. Consider reducing processed foods, meat and sweets. The Mediterranean and MIND diets—the diets most studied so far by major research organizations around dementia—recommend limiting processed foods, meat, sweets and dairy. Instead, those diets emphasize eating more fruit, vegetables, legumes, whole grains, nuts, olive oil and fish. Many other cultures and regions, of course, also have vegetable-, legume-, nut- and fish-focused diets whose principles could apply.
  2. Enjoy a variety of foods in many different colours:
    • Blue and purple fruits and vegetables tend to be packed with anti-oxidants. Blackberries, blueberries, ube, purple cabbage and plums are all great food choices.
    • Go green every day with fruits and vegetables that are good for your brain and also benefit bones, teeth and vision. Green options include avocados, broccoli, celery, cucumbers, peas, spinach, nori, edamame, pears, honeydew melon and many more.
    • Choose white, tan and brown fruits and vegetables such as bananas, cauliflower, potatoes, turnips, daikon, onions and garlic.
    • Add orange and yellow fruits and vegetables such as grapefruit, cantaloupe, butternut squash, peaches, papaya, oranges, sweet potatoes, yellow peppers and lemons to your plate.
    • Reach for reds every day. Beets, raspberries, red grapes, radishes, tomatoes, red peppers, watermelon, rhubarb, pomegranates and cherries are just a few excellent red choices.
  3. Find healthy ways to add flavour to your meals. A healthy diet can be tasty! Herbs, spices, nuts and seeds are all healthy add-on options.
  4. Be mindful of your eating habits. Choose appropriate portion sizes, eat healthy snacks and drink plenty of water – Canada's Food Guide recommends that you make water your drink of choice.
  5. Plan meals in advance. By developing healthy eating patterns, you don't leave your diet to chance. There are meal planning apps and websites that can help you plan ahead, cook your own food and decide what recipes work best even if you have a busy schedule.

Make conscious and safe choices

"Better to be safe than sorry!"

"All things in moderation."

These common sayings have more relevancy than ever when it come to making the right choices for your brain health! Our ability to maintain life-long brain health is very much influenced by the choices we make in our daily lives.

Research has found that, next to aging (and in some cases, genetics), lifestyle and environmental factors are the most influential factors in determining one's risk for dementia.

Therefore, it's important to protect your body, at any age, for lifelong brain health. Make safe choices that protect you from ailments and trauma that would otherwise increase your risk of dementia.

Making conscious and safe choices can reduce these risk factors for dementia:

  • Head injuries
  • Hearing loss
  • High alcohol consumption
  • Smoking

Five tips for making conscious and safe choices

  1. Avoid habits that harm your body. Examples of harmful habits include smoking, listening to music too loudly and excessive drinking. They might be fun in the short-term, but not in the long run!
  2. Protect your head. Wear a helmet if you're engaging in intense physical activity like skating, skiing, skateboarding, scootering, rollerblading or cycling. Set a good example and ensure that children in your care wear appropriate helmets too.
  3. Assess the safety of the environment around you. Do you work or live in an area where you are continually exposed to risks such as loud sounds or vehicle pollution? Does your home have handrails or grab bars installed that improve accessibility and prevent falls? By being aware of potential dangers in your environment, you can take steps to counter them.
  4. Track your numbers. Doing so will make it easier for you to keep your blood pressure, cholesterol, weight and blood sugar levels within recommended ranges. After all, all of these conditions increase your risk for dementia.
  5. See your doctor regularly. This will help you address specific health concerns you may have, including diet, hearing evaluations and physical activity.

Manage stress

Experiencing stress is a part of everyday life, but when it persists over time, it can cause vascular changes and chemical imbalances that are damaging to the brain and other cells in your body.

By managing or lowering your stress, you can improve your brain health and reduce your risk of dementia.

Managing your stress can reduce these risk factors for dementia:

  • Depression
  • High blood pressure

Five tips for managing stress

  1. Recognize the symptoms of chronic stress:
    • Emotional: Depression, tension, anxiety, anger, worry and/or fear.
    • Physical: Headaches, fatigue, insomnia and/or sweating.
    • Mental: Poor concentration, memory loss, indecisiveness and/or confusion.
    • Behavioural: Fidgeting, overeating, alcohol and/or drug abuse.
  2. Take personal time for yourself. Exercise, relaxation, entertainment, hobbies and socializing are essential parts of our health and well-being. Everyone needs to find a balance that limits stress and helps maintain optimal health. Methods could be through meditation, deep breathing, massage or physical exercise – the key is to explore a variety of techniques and find those that work for you.
  3. Set realistic expectations. We often assume our expectations are reasonable, but this isn't always the case. By identifying what you can change and what cannot be changed, you can single out unrealistic expectations. Then, you can focus on what can benefit yourself right away.
  4. Get plenty of sleep. Most people need at least seven hours of sleep per night. Sleep deprivation can significantly impair your memory, mood and function.
  5. Seek and accept support. Reach out to a friend or family member that you trust. Talk about what's giving you stress. If symptoms of stress persist, contact your doctor.

Challenge your brain

A 2020 University of California study showed that maintaining an overall healthy lifestyle—one that includes cognitive and physical activity, a high-quality diet and social engagement—can reduce the risk of developing Alzheimer’s disease.

Some people living with dementia have also reported that challenging their brain helps them live well and manage their daily activities such as finances, cooking or being active.

Five tips for challenging your brain

  1. Pursue life-long learning. Learn new things and take up new hobbies.
  2. Play games. Examples of brain-challenging games can include chess, tabletop games, video games, word and number puzzles, jigsaws, crosswords, sudoku and memory games. For games on your computer, your tablet or your phone, find games where you can play and interact with other people.
  3. Maintain a routine and use reminders. Maintain a routine and continue to take part in activities you always love to do (when possible). Use reminders and other tips and strategies when completing daily activities.
  4. Engage in cultural activities. Check out what's happening in your area, like a community celebration, music event, or art show. After the event, discuss what you saw with a friend.
  5. Cross-train your brain. What's something you're not good at doing? Work to improve it and give your brain some flexibility. Try a variety of challenges instead of sticking to one particular area. Some people living with dementia try to use their non-dominant hand for everyday activities like brushing teeth.
