Nearly half of all dementia cases may be delayed or prevented. Here’s what the latest research says — and how to put it into practice right here in Metro Vancouver.
If you’ve been searching for ways to reduce your risk of dementia, you’re already doing one of the most protective things there is: paying attention. Dementia can feel like something that simply happens to us as we age, decided long before we notice the first missed word or misplaced keys. The research says otherwise.
In 2024, the Lancet Commission on Dementia Prevention, Intervention, and Care — a standing panel of the world’s leading dementia researchers — updated its landmark report with a striking finding: as much as 45% of dementia cases worldwide could potentially be prevented or delayed by addressing 14 modifiable risk factors across a person’s life. Not eliminated entirely, and not a guarantee for any one person — but a real, evidence-backed opportunity to shift the odds.
For families here in Metro Vancouver — from Kitsilano to Coquitlam, North Vancouver to Richmond — that’s genuinely good news. It means brain health isn’t only about waiting for a diagnosis and reacting. It’s about the everyday choices, the walk along the Seawall, the hearing test you’ve been putting off, the coffee with a neighbour, that quietly add up over decades.
This guide breaks down what actually moves the needle, grounded in the latest research, with practical ways to apply it in our own city.
What the Research Actually Says
The Lancet Commission’s 14 modifiable risk factors span three life stages — early life, midlife, and later life — which is part of why prevention is a long game rather than a single New Year’s resolution. The factors include limited early education, hearing loss, high blood pressure, smoking, obesity, depression, physical inactivity, diabetes, excessive alcohol use, traumatic brain injury, air pollution, social isolation, untreated vision loss, and high LDL cholesterol in midlife.
No single factor accounts for the bulk of the risk on its own. Instead, it’s the accumulation — and the good news buried in that is that progress on any one front helps, even if you can’t tackle all fourteen at once.
Seven Brain-Healthy Habits Worth Building
1. Move most days of the week
Regular physical activity supports blood flow to the brain and helps manage several risk factors at once — blood pressure, blood sugar, weight, and mood. It doesn’t need to be intense. A brisk 30-minute walk most days, whether that’s a loop of Trout Lake, a stroll along the Ambleside waterfront in West Vancouver, or a few laps of Burnaby Lake, counts.
2. Get your hearing and vision checked
Hearing loss and untreated vision problems are two of the more surprising entries on the Lancet Commission’s list — and two of the easiest to act on. Uncorrected hearing loss can quietly encourage social withdrawal and reduce the brain’s stimulation, while poor vision limits activity and independence. An annual hearing and vision check, through your family doctor or a local audiologist or optometrist, is a small appointment with outsized long-term value.
3. Keep blood pressure, blood sugar, and cholesterol in range
Midlife hypertension, diabetes, and high LDL cholesterol were all flagged as significant contributors to dementia risk. These are the same numbers your doctor already tracks at your annual physical — ask about them directly, and treat “borderline” readings as worth addressing now rather than later.
4. Stay socially connected
Social isolation is one of the more consistently cited risk factors in dementia research, and it’s one that tends to creep up quietly — especially after retirement, a move, or the loss of a spouse. Metro Vancouver has a strong network of seniors centres and community programs built exactly for this: the West End Seniors’ Network, Kerrisdale and Kitsilano community centres, and the South Vancouver Neighbourhood House all run regular drop-in and social programming for older adults.
5. Protect your head
Traumatic brain injury has a documented link to later dementia risk. Simple precautions — wearing a helmet while cycling the Seawall or skiing at Cypress or Grouse, using a cane or walker if balance has become a concern, and fall-proofing the home (secure rugs, good lighting, grab bars) — genuinely matter more than they get credit for.
6. Keep learning and stay curious
Early-life education is one of the Commission’s life-course factors, but the protective idea behind it — building “cognitive reserve” — applies at any age. Taking a class through Vancouver Community College’s continuing studies program, joining a book club at your local library branch, or picking up a new language or instrument all give the brain fresh material to work with.
7. Rethink alcohol and smoking
Excessive alcohol consumption and smoking both appear on the risk list. If cutting back or quitting has been on your mind, BC’s smoking cessation program offers free support and nicotine replacement therapy through local pharmacies and your family doctor.
Local Resources for Brain Health in Metro Vancouver
You don’t have to figure this out alone, and you don’t have to look far. A few places to start:
- Alzheimer Society of B.C. — First Link Dementia Helpline: 1-800-936-6033, with support available in Punjabi, Hindi, Urdu, and Cantonese. Their Vancouver resource centre at 828 West 8th Avenue holds drop-in hours for anyone with questions about dementia risk, diagnosis, or care.
- Vancouver Coastal Health regional programming: education sessions and support groups for brain health and dementia across Vancouver, Richmond, and the North Shore.
- Community centres: most Metro Vancouver community centres — from Marpole to Port Moody — run seniors’ fitness, social, and lifelong-learning programs that touch on several risk factors at once.
Prevention Is One Part of the Picture — Support Is the Other
Reducing risk is worth doing at any age, but for families already supporting a loved one with early memory changes or a dementia diagnosis, prevention research is only part of the conversation. That’s where LivePeace 24/7 Seniors Home Care comes in.
We provide flat-rate, in-home care for seniors across Metro Vancouver — including Vancouver, Burnaby, Richmond, North and West Vancouver, and New Westminster — built around the same brain-healthy fundamentals in this guide: staying active, staying socially engaged, and staying safe at home. If you’re navigating dementia risk, an early diagnosis, or simply want a second set of hands and eyes at home, we’re happy to talk through what support could look like for your family.

Frequently Asked Questions
Can dementia really be prevented?
Not entirely, and not for everyone — some risk comes from genetics and aging that can’t be changed. But according to the 2024 Lancet Commission, up to 45% of dementia cases worldwide are linked to modifiable risk factors, meaning meaningful prevention is possible for a large share of cases.
What is the biggest risk factor for dementia?
No single factor dominates. The Lancet Commission’s 14 factors — including hearing loss, high blood pressure, high LDL cholesterol, smoking, physical inactivity, and social isolation — each contribute a piece, which is why a broad, whole-lifestyle approach works better than focusing on just one habit.
At what age should I start thinking about dementia prevention?
Earlier than most people expect. Researchers group risk factors into early-life, midlife, and later-life categories, which means habits in your 40s and 50s — like managing blood pressure and staying socially active — carry real weight decades before symptoms would ever appear.
Where can Metro Vancouver seniors get a hearing or vision check?
Most family doctors can refer you to a local audiologist or optometrist, and many Metro Vancouver pharmacies and clinics offer hearing screenings directly. The Alzheimer Society of B.C.’s First Link Helpline (1-800-936-6033) can also point you toward local resources.
Does LivePeace provide care for seniors at risk of or living with dementia?
Yes. LivePeace 24/7 Seniors Home Care provides flat-rate, in-home support across Metro Vancouver for seniors managing dementia risk factors or an existing diagnosis, including companionship, safety supervision, and daily living support.
