A recent analysis of two National Institutes of Health–funded studies followed nearly 3,000 adults and uncovered something powerful: those who consistently practiced four or more healthy lifestyle habits had a 60% lower risk of developing Alzheimer’s disease.
These habits weren’t complicated or out of reach—they included staying physically active, not smoking, enjoying alcohol in moderation, eating a high-quality diet, and keeping the mind engaged through cognitive activities. Not a breakthrough drug or cutting-edge treatment. Just a combination of everyday choices that, together, can make a meaningful difference in long-term brain health.
Whether you live in Teaneck, NJ, Hackensack, Englewood, or anywhere across Bergen County, the science is clear: the habits you practice each day have a powerful effect on how your brain ages. And the best part? It's never too late to start.
In honor of Brain Awareness Week, here are six evidence-based habits that support cognitive wellness well into your 70s, 80s, and beyond.
Feed Your Brain With Purpose
Your brain consumes roughly 20% of your body's energy, so what you eat matters more than you might think. The MIND diet—a hybrid of the Mediterranean and DASH diets—was specifically designed by researchers to support brain health. It emphasizes leafy greens, berries, nuts, whole grains, fish, and olive oil while limiting red meat, butter, and processed sugar.
A study published in Alzheimer's & Dementia found that people who closely followed the MIND diet had brains that functioned as though they were 7.5 years younger than their actual age. You don't have to overhaul your entire kitchen overnight. Small changes like swapping white bread for whole grain, adding a handful of blueberries to breakfast, or cooking with olive oil instead of butter add up over time.

Move Your Body to Boost Your Mind
Exercise isn't just about staying physically strong. It's one of the most effective tools for protecting your brain. When you move, blood flow to the brain increases, delivering oxygen and nutrients that help neurons stay healthy and even grow.
The Lancet Commission on Dementia Prevention identified physical inactivity as one of the top modifiable risk factors for cognitive decline. You don't need to run marathons. Walking 30 minutes a day, gentle yoga, swimming at your local pool in Paramus or Fort Lee, or even chair-based exercises all count.
What matters is consistency. Aim for movement most days of the week, and try to mix in activities that raise your heart rate with those that improve balance and flexibility. Our handbook to vibrant living has more ideas for staying active at every fitness level.
Social Connection as Cognitive Medicine
Loneliness doesn't just feel bad—it's a measurable risk factor for dementia. A 2022 study in the journal Neurology found that socially isolated older adults had a 26% higher risk of developing dementia compared to those with regular social contact.
Conversation, laughter, shared meals, and group activities all stimulate different regions of the brain simultaneously. They require you to listen, respond, remember details, read emotions, and think on your feet, all of which keep neural pathways active.
For seniors living in communities like Teaneck, River Edge, Bergenfield, and Leonia, there are many ways to stay connected: volunteering at a local organization, joining a book club at the library, attending a faith community, or simply meeting a neighbor for coffee each week.
Challenge Your Brain, But Make It Fun
There's an important distinction between passive entertainment and active cognitive engagement. Watching television for hours doesn't give your brain much of a workout. But learning a new card game, solving crossword puzzles, picking up a musical instrument, or taking a continuing education class at a community center in Englewood or Ridgefield Park? Those activities build and strengthen neural connections.
The key is novelty and challenge. Your brain benefits most when it encounters something unfamiliar or slightly difficult. Once an activity becomes automatic, its cognitive benefits diminish. So if you've mastered Sudoku, try learning chess. If you've read the same genre for years, explore something new.
Research from the Mayo Clinic found that older adults who engaged in mentally stimulating activities at least once or twice a week had a significantly lower risk of mild cognitive impairment. The activity itself matters less than the effort your brain puts in.
Prioritize Sleep Like It's Medicine
During deep sleep, your brain activates its glymphatic system, essentially a self-cleaning mechanism that flushes out waste products, including beta-amyloid plaques associated with Alzheimer's disease. When you consistently miss quality sleep, that cleaning process gets disrupted.
Most adults over 65 need seven to eight hours of sleep per night, but many get far less. Common culprits include untreated sleep apnea, medication side effects, chronic pain, and poor sleep habits.
Here are a few strategies that can help:
-
Keep a consistent schedule. Go to bed and wake up at the same time every day, including weekends.
-
Limit screens before bed. The blue light from phones and tablets suppresses melatonin production.
-
Create a cool, dark environment. Your bedroom should feel like a cave—quiet, dark, and slightly cool.
-
Talk to your doctor if you snore heavily, wake frequently, or feel unrested despite spending enough time in bed.
Sleep is not a luxury. For brain health, it's essential.
Manage Stress Before It Manages You
Chronic stress floods the brain with cortisol, a hormone that, over time, can shrink the hippocampus, the brain region most critical for memory. A study from the University of Texas Health Science Center found that older adults with elevated cortisol levels performed worse on memory tests and had smaller brain volumes.
Stress management looks different for everyone. For some seniors in Dumont, New Milford, or Bogota, it might be a daily walk through a local park. For others, it could be meditation, deep breathing exercises, gardening, or spending time with grandchildren. The method matters less than the commitment to regular practice.
Mindfulness-based stress reduction (MBSR) programs, widely available across northern New Jersey, have been shown to reduce anxiety and improve attention in older adults. Even five minutes of focused breathing each morning can shift your baseline stress level over time.
Small Steps, Big Impact
Brain health isn't about perfection. It's about patterns. You don't need to adopt all six habits at once. Start with one that feels manageable. Maybe this week you add a daily walk. Next month, you try a new recipe from the MIND diet. Over time, these small choices compound into something powerful.
The science is encouraging: your brain retains the ability to form new connections and adapt throughout your entire life. Neuroplasticity doesn't have an expiration date.
