Alzheimer's disease - Prevention (2024)

As the exact cause of Alzheimer's disease is still unknown, there's no certain way to prevent the condition. But a healthy lifestyle can help reduce your risk.

Reducing your risk of cardiovascular disease

Cardiovascular diseasehas been linked with an increased risk of Alzheimer's disease and vascular dementia.

You may be able to reduceyour risk of developing these conditions– as well as other serious problems, such asstrokes and heart attacks– by taking steps to improve your cardiovascular health.

These include:

• stopping smoking
• keeping alcohol to a minimum
• eating a healthy, balanced diet, including at least 5 portions of fruit and vegetables every day
• exercising for at least 150 minutes every week bydoing moderate-intensity aerobic activity (such as cycling or fast walking), or as much as you're able to
• making sure your blood pressure is checked and controlled throughregular health tests
• if you have diabetes, make sure you keep to the diet and takeyour medicine

Other risk factors for dementia

The latest research suggests that other factors are also important, although this does not mean these factors are directly responsible for causing dementia.

These include:

• hearing loss
• untreated depression (although this can also be a symptom of dementia)
• loneliness or social isolation
• a sedentary lifestyle

The research concluded that by modifying all the risk factors we're able to change, our risk of dementia could be significantly reduced.

Staying mentally and socially active

There's some evidence to suggest that rates of dementia are lower in people who remain mentally and socially active throughout their lives.

It may be possible to reduce your risk of Alzheimer's disease and other types of dementia by:

• reading
• learning foreign languages
• playing musical instruments
• volunteering in your local community
• taking part in group sports, such as bowling
• trying new activities or hobbies
• maintaining an active social life

Interventions such as "brain training" computer games have been shown to improve cognition over a short period, but research has not yet demonstrated whether this can help prevent dementia.
