Can Alzheimer's disease be prevented?

Alzheimer's disease, also known as senile dementia, can be prevented, although the effectiveness varies from person to person. Methods for preventing Alzheimer's disease mainly include: 1. Dietary regulation: Maintain a diet low in salt, low in fat, and high in vitamins. Consume more fruits and vegetables, and avoid foods high in oil and salt. 2. Mental training: Engage in appropriate calculation and thinking exercises, such as math problems and intellectual games, which can stimulate brain nerve activity and effectively prevent or delay disease progression. 3. Maintain healthy sleep patterns: Ensure sufficient sleep and avoid excessive fatigue and staying up late, which helps maintain normal metabolic and immune functions. 4. Moderate exercise: Perform appropriate aerobic exercises, such as walking, jogging, and swimming, which can promote blood circulation and improve cardiopulmonary function.
