There's no lifestyle factor that's been conclusively shown to reduce your risk of Alzheimer's disease. However, some evidence suggests that the same factors that put you at risk of heart disease may also increase the chance that you'll develop Alzheimer's. Examples include:
Lack of exercise
Smoking
High blood pressure
High blood cholesterol
Poorly controlled diabetes
A diet lacking in fruits and vegetables
Lack of social engagement
These risk factors are also linked to vascular dementia, a type of dementia caused by damaged blood vessels in the brain. Working with your health care team on a plan to control these factors will help protect your heart — and may also help reduce your risk of Alzheimer's disease and vascular dementia.
Lifelong learning and social engagement
Studies have found an association between lifelong involvement in mentally and socially stimulating activities and reduced risk of Alzheimer's disease. Factors that may reduce your risk of Alzheimer's include:
Higher levels of formal education
A stimulating job
Mentally challenging leisure activities, such as reading, playing games or playing a musical instrument
Frequent social interactions
Scientists can't yet explain this link. One theory is that using your brain develops more cell-to-cell connections, which protects your brain against the impact of Alzheimer-related changes. Another theory is that it may be harder to measure cognitive decline in people who exercise their minds frequently or who have more education. Still another explanation is that people with Alzheimer's disease may be less inclined to seek out stimulating activities years before their disease can be diagnosed.
Signs:
1. Memory loss that disrupts daily life. One of the most common signs of Alzheimer’s, especially in the early stages, is forgetting recently learned information. Others include forgetting important dates or events; asking for the same information over and over;
