Educational content can help, but significant mood, memory, anxiety, or attention symptoms should be assessed by a qualified professional.
Overview
Dr. Matthew Tenenbaum, associate medical officer of health in Wellington-Dufferin-Guelph, discusses brain health awareness month and what everyone should know about cognitive decline and dementia prevention.
How It Affects People
Dementia currently affects over 700,000 Canadians, and that number is expected to rise as the population lives longer. Early signs include gradual memory difficulties, trouble with planning and judgment, and behavioral changes. Dr. Tenenbaum emphasizes that these symptoms are slowly progressive — beginning as minor issues but worsening over months and years until daily functioning becomes significantly impaired. Not all memory problems indicate dementia, but a pattern of slow, steady decline should not be ignored. The encouraging message is that lifestyle habits adopted at any age can reduce dementia risk later in life. Dr. Tenenbaum outlines five key protective strategies: eating a balanced diet rich in iron, fruits, and vegetables to promote blood flow to the brain. Staying physically active — ideally 150 minutes per week of moderate to high-intensity exercise — which also reduces risk factors like high blood pressure, heart disease, and diabetes that are themselves significant drivers of dementia. Maintaining social connections through community engagement and friendships. Challenging the brain regularly through puzzles, education, and learning new skills. And getting 7–9 hours of quality sleep per night, which plays a direct role in long-term brain protection.
Practical Takeaway
The overarching point: these aren't brain-specific interventions — they're the same general health habits that protect the entire body. By staying healthy overall, you protect your mind as well.
