To limit this risk
, it is recommended to adopt a balanced diet, practice regular physical activity, reduce salt intake, and limit processed foods. The heart and brain are more connected than we think.

2. Chronic stress and sleep disorders

Stress, often trivialized, is a factor that should not be underestimated. In cases of prolonged stress, cortisol levels (the stress hormone) remain high. However, this hormone damages brain cells and impairs memory. Therefore, poorly managed stress can, in the long term, contribute to the development of Alzheimer’s disease.

Added to this is the issue of sleep. During the night, the brain “cleanses” itself, particularly by eliminating beta-amyloid proteins, which are responsible for the plaques characteristic of the disease. Lack of sleep, whether in quantity or quality, hinders this natural process and weakens the central nervous system.

3. Lack of cognitive stimulation and isolation

Our brain is an organ that needs stimulation. In the absence of regular intellectual activity, neural connections weaken. Reading, learning, playing, debating: all of these help maintain brain circuits and strengthen what is known as “cognitive reserve.”

Alzheimer’s disease affects people who are socially or intellectually isolated more severely. Prolonged loneliness increases the risk of depression, which is recognized as an aggravating factor. Maintaining social connections and stimulating activities is therefore essential at any age.
