How to Reduce Dementia Risk and Protect Your Brain

Dementia prevention strategies include six evidence-based approaches - cardiovascular health monitoring, physical and mental activity, social engagement, nutritious eating, hearing protection, and emotional wellbeing support - that research suggests may reduce cognitive decline risk and protect long-term brain health.

What if protecting yourself against dementia isn't as hopeless as you think? While no approach guarantees prevention, emerging research reveals six evidence-based strategies that may significantly reduce your risk while enhancing your quality of life today.

Can You Prevent Dementia? Protecting Your Brain Health for the Future

Dementia represents one of the most challenging conditions affecting cognitive function and memory. The experience of receiving a dementia diagnosis—or watching someone you love navigate this condition—can feel overwhelming and disorienting.

Scientists continue investigating what causes dementia and which lifestyle factors might lower risk. While much remains unknown, emerging research suggests that how we live today may influence our brain health decades from now. Even as young adults, we can take meaningful steps to support cognitive wellness and potentially reduce dementia risk later in life.

Understanding dementia

Dementia describes a collection of symptoms resulting from damage to brain nerve cells caused by various diseases. According to the American Psychological Association, dementia involves widespread deterioration of memory combined with decline in at least one other cognitive function—such as language, reasoning, or executive function.

These symptoms worsen progressively over time and may include:

• Memory loss that disrupts daily life
• Growing confusion and difficulty completing familiar tasks
• Language and comprehension challenges
• Changes in behavior and personality

While these symptoms sometimes accompany aging, dementia itself is not a normal part of getting older.

Forms of dementia

The term “dementia” encompasses several distinct conditions, each with unique characteristics:

Alzheimer’s disease

The most prevalent form of dementia, Alzheimer’s typically first manifests through difficulties with memory, thinking, language, or perception.

Vascular dementia

The second most common type, vascular dementia presents varied symptoms that often include challenges with planning, organizing, following multi-step processes, and reduced mental processing speed.

Dementia with Lewy bodies (DLB)

DLB develops when protein deposits called Lewy bodies accumulate in brain cells. This buildup progressively affects concentration, movement, sleep patterns, and can cause delusions.

Frontotemporal dementia (FTD)

Sometimes called Pick’s disease or frontal lobe dementia, FTD is less common and primarily impacts personality, behavior, and language abilities.

Additional forms

Approximately 95% of dementia diagnoses fall into one of these four categories. However, other related dementias exist, and some individuals develop mixed dementia, showing symptoms of multiple types simultaneously.

Can we prevent dementia?

Without a definitively identified cause for dementia, predicting and preventing the condition remains extraordinarily challenging. Currently, no approach guarantees complete prevention.

That said, we can take actions that may reduce dementia risk while simultaneously enhancing overall quality of life. Researchers have identified numerous risk factors potentially contributing to various dementia forms—ranging from untreated hearing loss to chronic social isolation. Cultivating healthy habits, maintaining mental engagement, and addressing emotional wellbeing may help mitigate these risks. Such approaches might also slow symptom progression if dementia does develop.

Six strategies for reducing dementia risk

Research from Johns Hopkins School of Medicine suggests that approximately one in three dementia cases may be preventable. Consider these six evidence-informed approaches to supporting brain health and potentially building resilience against dementia.

Monitor cardiovascular health markers

Elevated blood pressure and blood sugar levels correlate with increased dementia risk. High blood pressure raises stroke and vascular dementia risk, while elevated blood sugar increases vulnerability to diabetes, cardiovascular disease, stroke, and dementia.

Many people can improve these health markers through lifestyle modifications:

• Engaging in regular physical activity and prioritizing nutritious foods
• Eliminating tobacco and reducing substance use
• Taking prescribed medications as directed by healthcare providers
• Monitoring glucose levels regularly

If you are struggling with substance use, contact the SAMHSA National Helpline at 1-800-662-HELP (4357) to receive support and resources. Support is available 24/7.

Your primary care provider can assess your blood pressure and blood sugar levels and recommend appropriate interventions for optimizing current and future health.

Nourish body and mind

Research indicates that nutritious eating patterns may slow cognitive decline. What constitutes “nutritious” varies by individual, but standard medical recommendations provide a reasonable starting point. Tuning into your body’s signals, making thoughtful food choices, and discovering movement you enjoy can support dementia prevention while enhancing overall wellbeing.

Developing body awareness might involve:

• Moving regularly while honoring rest when tired or unwell
• Staying adequately hydrated throughout the day
• Recognizing and responding to natural hunger and fullness signals
• Periodically checking in with yourself and addressing emotional, physical, or social needs
• Moderating alcohol consumption

Building trust with your body takes time, but this process offers meaningful benefits that may include reduced dementia risk and improved health across multiple dimensions.

Keep body and brain active

Regular physical activity—whether walking, dancing, swimming, or playing with pets—benefits your cardiovascular system and may help prevent various health conditions. Your brain also thrives on exercise, both physical and mental. Consider incorporating these activities into your routine:

• Learn something new: a musical instrument, a craft like pottery or woodworking, or a foreign language
• Engage with puzzles, board games, or card games
• Pursue creative projects
• Complete daily crosswords or other word games
• Explore diverse reading materials across multiple genres
• Protect your hearing by using ear protection in loud environments and limiting headphone volume and duration
• Prevent head injuries by wearing helmets during activities like cycling or skating

A key principle for both mental and physical exercise is variety. Challenging your mind and body with diverse daily activities creates a foundation for sustained cognitive and physical health.

Cultivate meaningful connections

Your relationships with friends, family, and community may do more than provide emotional comfort—they might actually reduce dementia risk.

Social support networks serve as a powerful buffer against loneliness, which affects people across all age groups. The Centers for Disease Control reports that social isolation associates with a 50% increased dementia risk, based on a 2020 study of loneliness in older adults. While forming new connections can feel intimidating as we age, meaningful friendships can develop at any life stage.

To expand your social world, consider joining clubs or recreational groups, scheduling regular contact with existing friends, or volunteering in your community. You might discover people who share your interests or connect with individuals you never expected to meet. Either way, you combat isolation while potentially lowering dementia risk—a dual benefit worth pursuing.

If hearing difficulties make conversation challenging, discuss hearing aid options with your healthcare provider. Addressing hearing loss may improve both social engagement and cognitive health.

Prioritize your emotional wellbeing

Certain dementia risk factors remain outside our control. According to the National Institute on Aging, unchangeable factors that may increase dementia likelihood include:

• Age: Dementia occurs more frequently in older adults; age represents the single greatest known risk factor
• Racial identity: Research indicates that Black and Hispanic individuals face significantly higher dementia rates compared to white individuals
• Gender: Women experience higher lifetime dementia risk than men

Additional factors with potential dementia connections include air pollution exposure, hearing loss, and traumatic brain injuries.

Ongoing research continues exploring causes and treatments, with some clinical trials showing promise. Further investigation is essential for understanding these patterns and clarifying dementia’s causes so affected individuals receive appropriate support.

Consider therapeutic support

Some people find that therapy helps them navigate health concerns and build coping strategies. Whether you’re processing a recent diagnosis, supporting a loved one with dementia, or simply want to develop healthier daily practices, therapy can become a valuable component of comprehensive wellness.

Counseling provides space to address the emotional dimensions of health concerns, develop stress management techniques, and process the complex feelings that often accompany cognitive health worries. For family members caring for someone with dementia, therapy offers crucial support for managing caregiver stress and maintaining your own wellbeing.

Telehealth therapy as part of your wellness approach

Many people now choose telehealth therapy for its convenience and accessibility. Digital mental health platforms allow you to connect with licensed clinical social workers from home, eliminating travel time and geographical barriers.

At ReachLink, our licensed clinical social workers specialize in helping individuals address a wide range of concerns, including health anxiety, caregiver stress, and the emotional challenges that accompany chronic health conditions.

Research demonstrates that telehealth therapy delivers outcomes comparable to traditional in-person counseling. A 2022 study examined an online Acceptance and Commitment Therapy (ACT) program for family caregivers of people with dementia. The research confirmed that online ACT effectively reduced depressive symptoms, stress, and feelings of burden among dementia caregivers, with results matching those of in-person therapy. These findings suggest that telehealth platforms can make therapeutic support more accessible and affordable for those navigating dementia-related challenges.
