Physical and nutritional, the foundation for a healthy brain
Medical experts say lifestyle plays a key role in preventing dementia, including Alzheimer's disease. The disease often develops due to a combination of genetics, cardiovascular health and living habits.
Physical activity is a top factor. A study published at the 2025 Alzheimer's Association International Conference shows that regular walking has a protective effect against cognitive decline, even in people with susceptible genes. Suitable forms of exercise include running, swimming, yoga, dancing, or team sports.
In addition, scientific nutrition plays an important role in protecting the brain. The FINGER experiment (France) shows that a diet rich in vegetables, fish, lean meat and few processed foods can reduce the risk of Alzheimer's. Dr Brigid Dwyer, a neurologist at Massachusetts General Hospital (USA), emphasized: The pilot needs stable energy and nutrients. A balanced diet will not only maintain physical health but also strengthen long-term memory".
Manage stress and social cohesion
In addition to physical fitness and nutrition, stress management is key to maintaining alertness. Research shows that prolonged stress can affect brain structure, increasing the risk of mental decline. Effective methods include meditation, deep breathing, interacting with friends, or participating in artistic activities.
Social activities also play a big role. Interacting with the community helps reduce loneliness, improve spirit and thinking ability. People who regularly participate in groups, physical education classes, or community activities are at lower risk of cognitive decline.
In parallel, cognitive training such as learning foreign languages, playing chess, or participating in brain training programs have also been shown to help slow down the aging process of the brain.
Finally, the accountability factor makes the difference. The US POINter experiment in the US shows that participants with lifestyle intervention programs with guidance achieved better cognitive improvement than those in the self-medulation group. This proves that accompanying a coach, nutritionist or exercise group brings sustainable results.
In short, habits such as mobility maintenance, stress management, a scientific diet, social interaction, brain training and accountability are important foundations for preventing dementia and Alzheimer's disease.
