Aging Well: How Brain Health Helps Us Stay Engaged in Life

Most people spend very little time thinking about their brains. We notice our hearts when they race, our joints when they ache, our muscles when they feel sore after a long day. But the brain works quietly in the background, helping us navigate nearly every moment of our lives without asking for much attention in return.

It helps us learn new skills, solve problems, build relationships, make decisions, and hold on to the memories that shape who we are. It allows us to adapt to change, navigate challenges, and remain connected to the people and experiences that matter most. For much of life, those abilities are easy to take for granted.

That is one reason June's Alzheimer's & Brain Awareness Month offers an opportunity to think beyond a single disease and consider a broader question: what does it mean to age well?

For many people, aging well means far more than adding years to life. It means maintaining independence, continuing to learn, staying connected to family and friends, and remaining engaged in the activities that bring purpose and enjoyment. Increasingly, researchers and physicians understand that brain health plays an important role in each of those goals.

At the University of Texas Medical Branch (UTMB), physicians and researchers who study aging and neurological health are helping patients better understand the factors that influence brain health throughout life. Their work continues to expand our understanding of how the brain changes with age and what individuals can do to support cognitive health in the years ahead.

Understanding Brain Health

When people hear the phrase "brain health," they often think about memory. But the brain influences nearly every aspect of daily life, from attention and communication to decision-making, emotional well-being, movement, and the ability to carry out everyday tasks.

“Maintaining brain health is essential for aging well and staying engaged in the activities, relationships, and experiences that enrich our lives,” said Dr. Anna Fracassi, Assistant Professor in the UTMB Department of Neurology and faculty member of the Mitchell Center for Neurodegenerative Diseases and the Moody Brain Health Institute. “While aging is often associated with cognitive decline, research has shown that some individuals develop resilience mechanisms that help preserve brain function despite age-related changes or even the presence of Alzheimer’s disease pathology.”

Like the rest of the body, the brain changes over time. Some of those changes are expected. It may take longer to learn new information, multitask, or recall certain details than it did years earlier. These experiences can be a normal part of aging and are often very different from the more significant cognitive decline associated with diseases such as Alzheimer's.

Alzheimer's disease is the most common cause of dementia, a condition that affects memory, thinking, and reasoning abilities. While Alzheimer's often receives significant attention during June's Alzheimer's & Brain Awareness Month, experts increasingly emphasize that conversations about brain health should begin long before symptoms ever appear.

“Alzheimer’s disease is a progressive and irreversible brain disorder that gradually impairs memory, thinking and other cognitive abilities,” stated Dr. Xiang Fang, Professor, UTMB Department of Neurology. “As the disease advances, it can interfere with a person’s ability to perform everyday activities independently. Early diagnosis and treatment can help slow disease progression and maintain cognitive function and quality of life.”

Research over the past several decades has helped reshape how physicians think about cognitive health. While age and genetics remain important factors, scientists have learned that the brain is influenced by many of the same habits and health conditions that affect the rest of the body. As a result, maintaining brain health has become an important part of broader conversations about healthy aging.

The Habits Behind Healthy Aging

For many years, people viewed cognitive decline as an unavoidable consequence of getting older. While no one can eliminate every risk factor associated with Alzheimer's disease or other forms of dementia, research continues to show that certain lifestyle habits may help support cognitive function throughout life.

“Healthy habits such as regular physical activity, quality sleep, social engagement, and a balanced diet can support cognitive health and may strengthen the brain’s natural resilience,” added Dr. Fracassi.

The encouraging news is that many of these habits are already familiar. “The evidence is clear that staying physically active and socially connected supports brain health and helps older adults remain engaged in their lives,” said Dr. Melissa Morrow, Professor, UTMB School of Health Professions and Director, Sealy Center on Aging. “Through our work, we are studying how home-based technologies can help older adults maintain these habits, monitor changes in function over time, and stay connected to their care teams and families.”

Physical activity remains one of the most important contributors to healthy aging. Exercise supports cardiovascular health, helps maintain healthy blood flow throughout the body, and has been associated with improved cognitive function as people grow older. Whether it is walking with neighbors, swimming, cycling, gardening, or simply finding opportunities to move throughout the day, regular activity benefits both the body and the brain.

Nutrition also plays a role. The foods people eat affect many of the systems that support brain function, and growing evidence suggests that dietary patterns emphasizing fruits, vegetables, whole grains, lean proteins, and healthy fats may contribute to better overall health as people age.

Just as important are the connections people maintain with others. Conversations with friends, time spent with family, participation in community activities, volunteer work, and meaningful social relationships challenge the brain in ways that extend beyond simple companionship. Remaining socially engaged has been linked to better emotional well-being and may help support cognitive health throughout life.

The brain also benefits from continued learning. Reading, learning a language, playing an instrument, taking classes, exploring a new hobby, or developing a new skill all encourage the brain to remain active and adaptable. While there is no single activity proven to prevent dementia, experts consistently encourage lifelong learning as part of a healthy lifestyle.

Sleep represents another important piece of the puzzle. Although many people think of sleep primarily as a time for rest, researchers increasingly understand its role in memory, learning, and overall brain function. Consistently poor sleep has been associated with a variety of health concerns, including those that may affect cognitive health over time.

Managing chronic health conditions may be equally important. High blood pressure, diabetes, high cholesterol, hearing loss, and other medical conditions have all been linked to an increased risk of cognitive decline. Addressing these conditions early and working closely with healthcare providers can support both physical and cognitive well-being.

None of these habits offers a guarantee, and researchers continue to study exactly how different factors influence brain health. Together, however, they represent opportunities for individuals to take an active role in supporting their health as they age.

Recognizing When Something Has Changed

Because occasional forgetfulness is a common part of life, it can sometimes be difficult to recognize when memory concerns deserve additional attention.

Many people wonder whether they are experiencing normal age-related changes or something more significant. While there is no single symptom that confirms Alzheimer's disease, persistent changes in memory, reasoning, communication, judgment, or the ability to perform familiar tasks should not be ignored.

Often, family members notice the changes first. A loved one may begin repeating questions, struggling to follow conversations, becoming confused about familiar routines, or having difficulty managing tasks that once felt routine. These changes can emerge gradually, making them easy to dismiss at first.

“Alzheimer’s Disease (AD) is the most prevalent and deadly form of terminal dementia for which there is currently no cure. AD is characterized by signature brain pathology on the one hand and catastrophic cognitive decline on the other hand,” said Dr. Giulio Taglialatela, Vice President and Research Institute Director, UTMB Moody Brain Health Institute. “Treatment of patients that already present with AD clinical symptoms (no matter how mild) has proven to be little to no effective, suggesting that the brain offending events leading to symptomatic AD occur several years before AD can be clinically diagnosed. Targeting those initiating events would thus be critical for developing an effective cure for AD.”

Importantly, not all memory concerns are caused by Alzheimer's disease. Sleep disorders, medication side effects, vitamin deficiencies, depression, and other medical conditions can also affect cognitive function. Early evaluation can help identify potential causes and connect patients with appropriate treatment, support, and resources.

“Because changes in the brain often begin years before symptoms appear, research and early detection are critical,” said Dr. Agenor Limon, Associate Professor and Vice Chair for Research, UTMB Department of Neurology.

As researchers continue to learn more about Alzheimer's disease and other forms of dementia, one message remains consistent: early conversations can lead to earlier support and a better understanding of the resources available to patients and families.

Advancing Care and Research at UTMB

Although Alzheimer's disease remains one of medicine's most complex challenges, significant progress has been made in understanding how the disease develops and how it may be diagnosed and treated.

Researchers continue to study the biological changes that occur in the brain years before symptoms become noticeable, while advances in imaging, biomarkers, and emerging therapies are creating new opportunities for earlier detection and intervention. These developments are helping physicians better understand the disease and identify patients who may benefit from evolving treatment approaches.

At UTMB, faculty members across neurology, geriatrics, and related disciplines contribute to research, education, and patient care focused on aging and cognitive health. Their work reflects a broader commitment to improving quality of life for patients while helping train the next generation of physicians and scientists. Researchers are also working to better understand why some individuals maintain cognitive function despite age-related changes and disease-related pathology. “Our research focuses on understanding the biological processes that support resilience, we hope to develop new strategies to delay or even prevent neurodegenerative diseases, preserve cognitive function, promote independence, and improve the quality of life throughout aging,” Dr. Fracassi stated.

Dr. Limon added “Through participation in research studies and brain donation programs, individuals can make a lasting contribution to science, helping researchers unlock the mysteries of aging and develop better ways to prevent, detect, and treat Alzheimer’s disease for future generations.”

Looking Beyond Awareness

Alzheimer's & Brain Awareness Month encourages conversations about diseases that affect millions of individuals and families. It also provides an opportunity to think more broadly about the habits, relationships, and choices that support brain health throughout life.

Aging well is about far more than avoiding illness. It is about remaining engaged with the people, activities, and experiences that give life meaning. It is about continuing to learn, adapt, contribute, and connect.

While researchers continue to pursue new discoveries, there is growing recognition that brain health is something people can support throughout their lives. The habits that help protect physical health often benefit the brain as well, reinforcing the connection between overall well-being and healthy aging. Dr. Morrow added, “Our goal is to extend the period of healthy, independent living for as long as possible.”

Because when people think about aging well, they often think about something deeper than memory. They are thinking about maintaining the ability to participate fully in life, remain connected to others, and continue creating new experiences and memories for years to come.
