A neurologist explains that brain atrophy begins in the 30s–40s and accelerates with age, but lifestyle changes—such as a Mediterranean-style diet, regular exercise, learning new skills, meditation, and finding purpose—can slow or reverse shrinkage and help preserve memory and cognitive function.
A large study suggests that the optimal nightly sleep is about 6.4 to 7.8 hours. Sleeping too little or too much is associated with accelerated aging across multiple organs, and the piece offers tips to help people hit the “just right” amount.
A six-month randomized trial with 251 adults who had central obesity found no significant cognitive improvements from eating one avocado daily compared to a control group. Memory, processing speed, and executive function showed no meaningful gains, with any minor improvements likely due to practice effects rather than the avocado. Age did not alter the outcome, suggesting that a single nutrient-dense food is not a quick fix for brain health and that effects may depend on weight status or require broader dietary changes.
Dietitians say leafy greens and cruciferous vegetables are the top picks for brain, heart, and gut health thanks to fiber, vitamins, minerals, and anti-inflammatory compounds; broccoli sprouts are highlighted for their sulforaphane content and gut-supporting effects; beets, garlic, and onions are honorable mentions; variety is key—rotating these vegetables broadens the range of beneficial compounds and supports inflammation reduction, blood flow, and gut microbiome health across all three systems.
Neuroscientist Hannah Critchlow argues the brain’s basic structure hasn’t dramatically changed since the Stone Age, but we can cultivate overlooked skills—emotional intelligence, empathy, adaptability, and long‑term thinking—to thrive in the AI era. She highlights bioenergetics (mitochondria) as a foundation, the gut microbiome’s surprising link to altruism, and practical steps: practice self‑compassion, boost gut diversity, engage in daydreaming and nature walks to boost creativity through alpha brain waves, and maintain exercise, sleep, and healthy eating to power mental flexibility and resilience amid rapid change.
Researchers from Baycrest, the University of Toronto, and York University used AI to analyze how people describe complex images and found that patterns like frequent filler words, pauses, and word-finding difficulties can indicate cognitive decline and a higher risk of dementia. While some speech changes are normal aging, red flags include trouble expressing common words, short-term memory lapses, getting lost in familiar places, and repeatedly forgetting appointments. The study also notes lifestyle measures to lower dementia risk—controlling blood pressure, staying physically active, getting quality sleep, following a heart-healthy diet (e.g., Mediterranean), and ensuring good vision and hearing—though results are limited by cultural differences and the study’s cross-sectional design. If worried, consult a doctor.
A study of over 600 older adults found that strong overall brain health buffers the cognitive impact of early Alzheimer’s pathology, suggesting that lifestyle factors like regular exercise, a nutritious diet, good sleep, and new cognitive challenges can help preserve memory and thinking abilities. The research also notes preliminary evidence that higher socioeconomic status may lessen the effect of pathology on memory, underscoring the potential for public-health strategies to boost brain resilience across populations.
A large, multi-year study using the BrainHealth Index tracked about 4,000 adults aged 19–94 and found that consistent brain-healthy habits, cognitive training, and personalized coaching correlate with cognitive gains across the lifespan. Those with lower baseline scores improved the most, younger adults benefited as much as older ones, and the BrainHealth Project supports a personalized, scalable approach to enhancing brain health globally.
A large study of nearly 40,000 older adults (Adventist Health Study 2) found that regular egg consumption is associated with a lower risk of Alzheimer's disease over about 15 years: 17% lower for 1–3 eggs per month and 20% lower for 2–4 eggs per week. While not proving causation, researchers point to yolk nutrients such as choline (and other nutrients like B12, D, omega-3s, and lutein) that may support brain health, suggesting eggs can fit into a brain-healthy dietary pattern (like the MIND diet) but are not a standalone prevention.
Ronda Rousey and Gina Carano, two MMA pioneers who haven’t fought in years, prepare for Netflix’s live bout by undergoing extensive medical screening (CSAC-recommended brain and heart tests) and embracing recovery-focused training—saunas, cold plunges, hyperbaric oxygen and red-light therapy—aiming to counter age and ring rust while delivering a high-profile, durable comeback.
Alzheimer's Association guidance says challenging your mind with novel activities—like chess, learning a new instrument or language—and staying socially connected may help preserve brain health and cognitive reserve as you age; social isolation is linked to about a 70% higher risk of cognitive decline, and more on the 6-Step Challenge at rethinkyourbrain.org.
A long-term study of about 40,000 adults over 15 years links regular egg consumption with a lower risk of developing Alzheimer’s disease. Participants aged 65+ who ate at least one egg daily, five days a week, had up to a 27% lower risk than those who rarely or never ate eggs; even modest intake showed protection. Nutrients in eggs such as choline, omega-3s, lutein, and zeaxanthin are proposed as contributing factors. The study emphasizes eggs can be part of a balanced diet, though findings are observational, and funding included support from the American Egg Board.
A large, long-term study of 131,821 healthcare professionals found that moderate caffeinated coffee or tea intake—about 250–300 mg of caffeine daily (roughly two to three cups of coffee)—is associated with up to a 35% lower risk of dementia, especially before age 75, with benefits leveling off at higher intakes. Decaf users sometimes showed faster memory decline, and tea may offer strong protection at 1–2 cups daily; overall, moderation appears key and results may be influenced by other lifestyle factors.
CBS Mornings, in partnership with the Alzheimer's Association, highlights how diet can support brain health through the MIND diet—rich in fruits, leafy greens, whole grains and lean proteins while limiting processed foods and added sugars. The Alzheimer’s Association's 6-Step Challenge offers practical guidance and a food-log approach to build lasting brain-healthy habits, with resources at rethinkyourbrain.org.
The BBC highlights three enjoyable ways to protect the aging brain: boost spatial skills by navigating without GPS to strengthen the hippocampus; stay socially active to build cognitive reserve and lower dementia risk; and engage in lifelong learning to drive neuroplasticity and resilience.
