The number of people diagnosed and living with dementia in Canada is rising. By the year 2050, more than 1.7 million people are expected to be living with dementia in our country. But there is hope!

Together, we can take action to reduce our own dementia risk. 

While some risk factors for dementia can’t be changed – like genetics and age- there are many ways you can take action on to reduce your overall risk at any time of life.  

The more actions you take, the better! And if you can’t improve on one factor here, work on improving others – there's always a chance to take action and reduce your risk in one way or another. 

The Alzheimer Society recommends these 10 evidence-based ways to reduce your risk of developing dementia

Physical activity icon

Be physically active each day

Get moving! Walk, roll, jog, dance, swim, bike, garden or do chores or yard work. Any physical activity is better than none at all.  

Hearing icon

Protect, check and support your hearing

Hearing loss in midlife can increase dementia risk by an average of 90%. Use hearing aids if needed – they help reduce that risk. Protect your hearing from loud noises. Get your hearing tested.

Social activity icon

Stay socially active 

Stay connected and engaged with your family, friends and community. Virtual visits and activities count, too! Social isolation in later life can increase dementia risk by an average of 60%.  

Medical conditions icon

Manage your medical conditions and learn more about them  

In collaboration with your health-care provider, try to manage complex conditions such as diabetes and obesity as best you can. These two conditions in particular can increase dementia risk, among others.  

No smoking icon

Quit smoking 

Quitting or reducing smoking, even in later life, can improve your brain health and reduce your dementia risk. Ask your health-care team for support! 

Seek support for depression icon

Seek support for depression 

Depression is more than just feeling sad. Seeking depression treatment and support will help improve your mood and brain functioning, as well as allowing you to take action on other risk factors.  

Drink less alcohol icon

Drink less alcohol 

Research shows that drinking more than 12 standard drinks a week in midlife increases dementia risk by an average of 20%. Try out the growing number of mocktail and alcohol-free drink options instead! And if you need help with limiting alcohol, speak with your health-care provider. 

Protect heart icon

Protect your heart 

Working with your health-care provider, monitor and manage your blood pressure and heart health. What’s good for the heart is also good for the brain!

Brain injury icon

Avoid concussion and traumatic brain injury 

Steer clear of activities where you might put your brain at risk of harm. Follow traffic rules and pedestrian signals. Be aware of your surroundings. Play, travel and work safe! 

Sleep icon

Aim to get quality sleep 

Work toward sleeping well for 6 to 8 hours each night. If you experience sleep apnea or other sleep issues, talk to your health-care provider for treatment options.

The Landmark Study

The Alzheimer Society of Canada's Landmark Study uses data modelling to forecast the nation's dementia future. The study data is being analyzed in three reports. The first report, from 2022, looked at overall dementia numbers. The second report, released in 2024, looks at dementia across demographic groups. The third report, in 2025, will look at the economic impacts of dementia.
