Protect Your Brain Health: Expert Tips to Reduce Dementia Risk

As Canada observes Alzheimer’s Awareness Month this January, experts stress the importance of prioritizing brain health early in life. Dr. Nicole Anderson, a scientific director at the Kimel Family Centre for Brain Health and Wellness in North York, warns that the rate of dementia is projected to triple by 2050 as the population ages. Currently, over 51,000 individuals in Toronto and more than 300,000 across Ontario have been diagnosed with dementia, according to the Alzheimer’s Society of Toronto.

Urban living, particularly in large cities like Toronto, may heighten the risk of dementia due to increased exposure to environmental pollutants such as wildfire smoke and vehicle emissions. Recent data from Toronto Public Health revealed that Alzheimer’s disease and dementia were the leading causes of death among women in the city in 2023. Dr. Anderson highlighted that for every three people diagnosed with dementia, two are women, underscoring the gender disparity in dementia diagnoses.

While some individuals may face an inevitable risk of dementia, Dr. Anderson emphasizes that lifestyle choices play a significant role in prevention. “People often think, ‘My mother had it, so I will too,’ but that’s not necessarily true,” she stated. “We need to start thinking about brain health before we become older adults.”

Practical Steps for Brain Health

Dr. Anderson suggests that regular physical activity is one of the most effective ways to mitigate dementia risk. The Alzheimer’s Society of Toronto supports this view, noting that individuals who engage in regular exercise are less likely to develop associated conditions such as heart disease, stroke, and diabetes. The organization encourages setting achievable fitness goals, such as opting to walk instead of driving for short errands. Adults should aim for the recommended 150 minutes of moderate to vigorous physical activity each week.

In addition to exercise, Dr. Anderson advocates for a diet rich in “brain foods,” including fruits, vegetables, whole grains, and fatty fish. She advises reducing the intake of processed foods, meats, and sweets while encouraging a colorful variety of foods. Meal planning and mindfulness in eating habits can further enhance cognitive health.

Social engagement is another important aspect of maintaining brain health. The Alzheimer’s Society notes that an active social life can help reduce stress, depression, and feelings of isolation. Participating in community activities, volunteering, and nurturing existing relationships can all contribute positively to mental well-being.

Dr. Anderson also points out that managing stress is crucial for brain health. She explained, “Stress is toxic to the brain,” highlighting the importance of reducing daily stressors, such as long commutes. While individuals may not be able to change the length of their commute, they can make it more enjoyable by listening to music or podcasts during travel.

Culturally Sensitive Care and Disparities

Dr. Anderson emphasizes that the messaging surrounding brain health is often framed from a Western perspective. She advocates for culturally sensitive and personalized care, particularly in diverse cities like Toronto. A report from the Alzheimer’s Society of Canada indicates that rising dementia rates will disproportionately affect racialized individuals, although the condition does not impact all groups equally.

The report highlights that disparities in dementia care may stem from language barriers and a lack of awareness about dementia within various communities. Additionally, racialized individuals may face discrimination in healthcare settings, which can include inadequate communication and unequal access to treatments.

An example of culturally insensitive care is the common recommendation of the Mediterranean diet for brain health. While it promotes fruits and vegetables, Dr. Anderson stresses the importance of recognizing and incorporating traditional foods from different cultures, as they can offer similar health benefits.

As Canada navigates the complexities of dementia care, awareness and proactive measures are essential. By adopting healthier lifestyles and advocating for equitable healthcare, individuals can take significant steps towards preserving their brain health and reducing the risk of dementia.
