Fight Dementia with Fitness: The Science Behind Brain Health

Dementia, especially Alzheimer's disease, can be a life-altering diagnosis for both patients and their families. In this video, we explore the profound impact dementia has on individuals and their loved ones, while offering hope through prevention strategies, specifically focusing on the role of physical activity.
Dementia often strips away a person’s independence, leaving them dependent on family members or caregivers for day-to-day activities. This can cause emotional and financial strain on families. While memory-care facilities provide support for some, they are not accessible to everyone. This is why prevention of dementia is so critical—not only to reduce the burden on families but to lessen the financial and social impact on society as a whole.
We delve into the science behind dementia, particularly Alzheimer's disease, exploring how changes in the brain, such as beta-amyloid plaques and neurofibrillary tangles, contribute to cognitive decline. The video highlights the shared risk factors between dementia and cardiovascular disease, such as high blood pressure, diabetes, and lack of physical activity. But here's the good news: regular exercise can significantly reduce the risk of developing dementia.
From increasing blood flow to the brain to promoting neuroplasticity and the removal of harmful amyloid beta proteins, exercise is one of the most powerful tools in dementia prevention. Studies have shown that moderate exercise, like walking or aerobic activity, along with balance and coordination exercises, can lower dementia risk. In fact, even lifestyle habits from less developed countries, like those of the Tsimani people of Bolivia, demonstrate that an active lifestyle contributes to lower rates of dementia.
Whether you’re 25 or 75, it’s never too late to start! Simple strategies like the "talk test" can help you gauge your exercise intensity. Discover how just 150 minutes of moderate exercise a week can make a meaningful difference in maintaining brain health.
Join us in understanding how exercise can be your first line of defense against dementia—and how small lifestyle changes today can lead to a healthier, more independent future.
