Dementia Prevention: Easy Strategies Families at Genetic Risk Need to Know

Understanding whether there is a predisposition to memory loss can be a concern for those with family members facing dementia. However, there are reasons to feel optimistic, as specific daily routines have the potential to safeguard the brain and help prevent this condition.

Recently, attention has focused on a video featuring Hal Cranmer, an elder care expert who works to reduce hospital admissions through lifestyle choices. He presented a list of 23 practices to protect the brain in the aging process, including what he would do if his parents showed early signs of dementia. This led to a search for other expert recommendations on how to protect individuals with a family history of the disease.

Family history: a risk factor, not an inevitable fate

Although the presence of dementia in the family is a significant risk factor, it does not seal a person’s fate. Rachel Lambert, LPC, neurofeedback specialist and founder of Braincode Centers, assures that although genes may carry the predisposition, daily habits are crucial in determining whether the disease will manifest itself. Many of the controllable risk factors for dementia are related to practices that initially do not seem directly linked to the brain.

Essential measures to preserve the mind and reduce the risk of dementia

Although there is no guaranteed way to avoid dementia, it is possible to take important actions to keep your mind active for many years. To lower your risk of developing the condition long-term, consider incorporating the following smart strategies:

Protect Your Hearing for Brain Well-Being

Starting to protect hearing and sleep is crucial, as they represent underestimated brain problems, as Rachel Lambert warns. Untreated hearing loss puts a strain on the brain and is one of the most overlooked risk factors for dementia. The recommendation is to carry out hearing tests and use hearing aids, if necessary.

Cultivate new interests and challenge your mind

One of the most impactful attitudes for individuals is the development of “cognitive reserve,” which refers to the brain’s resilience, according to Kat Grassetti, clinical social worker and EMDR therapist. The key lies in maintaining an active mental curiosity. Staying cognitively challenged, not just busy, is key. Learning something complex, such as a new language, a musical instrument or a skill, builds this reserve, acting as a buffer that helps the brain maintain its functioning even as we age. Passivity, such as the simple act of scrolling your cell phone screen, does not contribute to this construction.

The priority of sleep in brain cleansing

Sleep deprivation is a critical lifestyle factor that increases the risk of dementia. Sleep should be seen as non-negotiable, as it is during the deep phases that the brain eliminates metabolic waste, including proteins linked to Alzheimer’s, as Lambert explains. This cleansing process, known as the glymphatic system, involves circulating cerebrospinal fluid to eliminate harmful substances. Laura Bojarskaite, neuroscientist at the University of Oslo, reinforces that sleep is one of the most important periods of brain maintenance, where memories are consolidated and neural circuits are reorganized. Neurologist Mill Etienne, who also prioritizes seven to eight hours of quality sleep, uses a smartwatch to monitor her routine and ensure consistency, underlining the unanimity of experts on the importance of rest.

The relationship between healthy fats and cognition

David Perlmutter, neurologist and author, seeks to empower people to prevent dementia with everyday actions. He argues that traditional neurology has focused on symptoms, but it is essential to focus on causes. Researchers have identified that women with Alzheimer’s often have low levels of omega-3s and high levels of saturated fats, indicating a lipid imbalance that can affect cognitive decline. Perlmutter recommends increasing your intake of omega-3 fatty acids through supplements or foods like wild salmon, suggesting that omega-3 levels may be crucial for preventing Alzheimer’s in women.

Protect the heart for brain health

It’s critical to focus on activities that improve cardiovascular function, such as regular exercise, controlling blood pressure, sugar and cholesterol levels, getting adequate sleep, and abstaining from smoking, according to Amy Fitzpatrick, MD, medical director of Bedrock Recovery Center. Rachel Lambert adds, stating that what benefits the heart is also good for the head, as the same blood vessels supply both. She emphasizes that regular aerobic exercise is one of the most effective measures to protect the body and should be seen as a treatment for the brain. This perspective is corroborated by neurologist Mill Etienne, who also highlights the interconnection between heart and brain health, stating that both benefit from the same care, such as controlling high blood pressure, diabetes and cholesterol.

The impact of active social life and mental health

Developing and maintaining robust social bonds, as well as treating conditions like depression, anxiety, or chronic stress, are equally vital to cognitive well-being, explains Dr. Fitzpatrick. She highlights that mental and brain health are intrinsically connected at all stages of life.

Practicing regular physical activity on a daily basis

Dr. Perlmutter suggests that constant movement, such as daily walks, can help combat memory loss associated with aging. He notes that walking 10,000 steps a day has the potential to reduce the risk of developing dementia by 50%. This recommendation is widely supported by neurologists like Mill Etienne, who prioritize including at least 30 minutes of moderate physical activity most days of the week, as well as looking for simple opportunities to move more, such as climbing stairs or parking far away.

Oral health: a gateway to overall body health

Kami Hoss, longevity and preventive dentistry specialist, founder of SuperMouth, defines the mouth as the gateway to overall health. He explains that inflammation in the gums allows bacteria and inflammatory byproducts to reach the bloodstream and, consequently, the brain. Flossing daily goes beyond aesthetics; it is one of the most effective ways to reduce chronic low-grade inflammation that silently contributes to neurodegeneration. For those with a family history of dementia, he advises giving oral health the same priority as controlling blood pressure or blood sugar.

Long-Term Perspectives for a Sharp Mind

Dementia prevention does not focus on a single technique for improving brain function. Both the Cochrane systematic review and the Harvard research on the topic indicate that what is most important is a set of healthy choices throughout life, not a single isolated habit. Hal Cranmer, in turn, advises that it is not necessary to adopt all strategies at once; Choosing three and starting to practice them in the same week can already generate positive results.

An ongoing investment in future brain health

Family history offers information, but does not determine a verdict, reiterates Rachel Lambert. The sooner you begin to see the brain as something trainable and protectable, the greater you will have control over the aging process. Dr. Fitzpatrick adds, stating that the best prevention strategy should be seen as a lifelong investment, and not as a one-off event. Even with genetic predisposition, active decisions made today can have a significant positive impact on developing brain health in the future.
