At BrainSavers, we know sleep is a cornerstone of brain+body fitness. It sharpens memory, stabilizes mood, boosts focus, and protects against cognitive decline as we age. Yet sleep deficiency is all too common — and preventable. Sleep deficiency occurs when you get too little sleep, sleep at irregular times, experience poor-quality sleep, or have an untreated sleep disorder. It is not just about feeling groggy; it impairs daily function and raises risks for serious health is

Maintaining physical activity is essential for older adults to preserve independence, improve our quality of life, and support cognitive health. As we age, our bodies and minds require specific types of exercise that address strength, balance, flexibility, and endurance. In this blog post, I share practical insights into effective exercises, supported by scientific research. I will also highlight how these exercises can be safely incorporated into daily routines to promot

Maintaining cognitive health is a priority for many as they age. The brain, like any other organ, requires proper nourishment to function optimally. What we eat can significantly influence memory, focus, and overall brain performance. In this article, I explore the role of nutrition in supporting brain health and highlight specific foods that help prevent cognitive decline. Understanding these dietary choices empowers us to take proactive steps toward preserving mental sharpn

Most of us think of Alzheimer’s as something that “just happens” in our 70s or 80s. In reality, the changes that lead to Alzheimer’s usually begin quietly in midlife—often 20 to 30 years before the first noticeable memory problems. Understanding this earlier timeline is empowering because it means the choices you make in your 40s, 50s, and 60s can meaningfully influence your brain health later on.

A recent study followed U.S. adolescents into adulthood and discovered some important lessons for all of us.  The study found that teens who felt more connected to their families were much more likely to report strong, satisfying social relationships in their 30s and 40s. This study focuses on adolescent experiences, but its message is also important to older adults and those who care for them.

According to an exciting recent study, most older adults can meaningfully extend their healthspan—the years lived free of major chronic disease—by making very small, combined improvements in sleep, movement, and nutrition, rather than dramatic changes in any one area.

Irregular sleep was not good in any study Among all the studies reviewed, irregular sleep was either neutral or harmful; none showed that irregular sleep was good for health or performance In some long‑term studies, each extra hour of fluctuation in sleep timing was linked to notably higher risk of metabolic syndrome and heart events.

I have long advocated that exercise can help reduce symptoms of depression in many adults, especially when done regularly at light to moderate intensity. An updated Cochrane review, just published, further supports my position. It suggests that exercise is generally safe and accessible and can be part of a broader plan to support mood, brain health, and overall well‑being.

The following comparison is designed to help you understand three brain- and heart-healthy eating patterns: the Mediterranean Diet, the DASH Diet, and the MIND Diet.

Harvard Medical School researchers have consistently warned that the brain supplement market is fraught with problems. Dr. Pieter Cohen, a physician and associate professor at Harvard Medical School, identified a disturbing pattern: many over-the-counter brain supplements contain unlisted, unapproved pharmaceutical drugs that aren't legal in the United States.

Artificial intelligence (AI) is a kind of “smart software” that learns from patterns in data so it can answer questions, make suggestions, or even hold a sort of conversation. For older adults, new AI tools can help with health, safety, finances, and staying socially connected—but they also pose risks we should be aware of. What is AI? – In Plain Language AI is computer technology that mimics certain forms of human thinking, such as recognizing speech, understanding language,

A study by Bruce Yankner and colleagues at Harvard, published in  Nature  (August 2025) , may represent a paradigm shift in understanding lithium's role in Alzheimer's disease (AD), demonstrating that lithium deficiency may be an early pathogenic event in AD. The key findings were that: 1) Lithium is the only metal significantly reduced in the brains of individuals with mild cognitive impairment (MCI). 2) Among all metals analyzed, lithium was uniquely decreased in individual

We all know a good night’s sleep feels great, but did you know it might also protect your brain from Alzheimer’s disease and vascular dementia? Recent research is shining a light on how poor sleep — whether from insomnia, sleep apnea, or disrupted brain cleansing during deep sleep — could increase your risk of cognitive decline and dementia over time.   What’s the Connection Between Sleep and Dementia? Your brain has a special system called the glymphatic system that clears o

The term “Japanese Walking” originated from a study done almost twenty years ago in Japan. It involves alternating three minutes of fast walking and three minutes of slower walking for 30 minutes. This type of interval walking helps your heart and muscles become stronger than walking at a single speed. And it is less boring for many. Research has shown that this form of aerobic workout boosts health for older and middle-aged adults, lowers blood pressure, and strengthens leg

There’s some exciting new research about core brain functions we have only recently learned about. As Eric Topol recently explained on Substack , the brain has its own cleaning and defense systems that operate continuously, and these systems become especially important as we age. The brain makes toxic waste products every day that need to be cleared away, like trash from a busy city. Special fluid-filled spaces and tiny channels help wash this waste out of the brain and into

Age-related brain problems like dementia, stroke, and depression are not just the “bad luck” of aging. Many cases are linked to everyday habits that can be changed, and it is never too late to change! A groundbreaking recent study  pulls together data from millions of people and shows which lifestyle choices matter most, so seniors, families, caregivers, friends, educators, and brain and physical fitness instructors can focus their energies where it counts. What the Study Did

Multimodal Lifestyle Program A “multimodal” approach means including several different lifestyle components at the same time to help protect the brain from Alzheimer’s disease and all-cause dementia. Instead of including just one activity, like physical exercise alone, it combines several items that all matter for brain health. What “multimodal” means In a multimodal program, people are usually asked to: Move their bodies regularly (like walking or other physical exercise) Ea

Music is more than just background noise. A recent study in the International Journal of Geriatric Psychiatry  looked at over 10,000 older adults and found that people who regularly listen to music had a lower risk of developing dementia and certain memory problems. The researchers suggest that music could be one simple, low‑cost way to support brain health as we age. Major Conclusion of This Research Study The findings from this study suggest that regular engagement in music

The New York Times recently ran a wonderful article about Dick Van Dyke as he approaches his 100th birthday and shares how he stays healthy and happy. You can read the full story here:  “How to Live to 100, According to Dick Van Dyke” (The New York Times) .  The article describes that a long, healthy, joyful life is not just about luck or genes. It comes from daily engaging habits that keep the body and brain strong: Van Dyke moves his body every day, including going to the
