Factors to Reduce Dementia Risk
Research suggests that making certain lifestyle changes can help reduce the risk of dementia. These factors include:
- Drinking less alcohol
- Reducing the risk of type 2 diabetes
- Limited exposure to traffic-related air pollution
Brain Network Vulnerability
Scientists have identified specific areas in the brain that are vulnerable to dementia. These areas are affected by various risk factors, including:
- Blood pressure
- Cholesterol
- Diabetes
- Weight
- Alcohol consumption
- Smoking
- Depressive mood
- Inflammation
- Pollution
- Hearing
- Sleep
- Socialization
- Diet
- Physical activity
- Education
Most Harmful Risk Factors
Among the modifiable risk factors, alcohol intake, diabetes, and traffic-related air pollution are identified as the most harmful for dementia risk.
Preventing Type 2 Diabetes
To lower the risk of developing type 2 diabetes, individuals can:
- Eat a healthier diet
- Maintain a healthy weight and waist size
- Engage in regular physical activity
Genetic and Modifiable Influences
Researchers have studied the genetic and modifiable influences on brain regions by analyzing brain scans of over 40,000 individuals. They found that certain variations in the genome influence the vulnerability of specific brain regions to dementia risk factors.
Significance of the Study
The study sheds light on the importance of promoting good brain health to prevent dementia. With up to 40% of dementia cases potentially preventable, there is a significant opportunity to reduce the impact of this condition on individuals and society.
Political Action for Brain Health
As the research highlights the impact of factors like air pollution on dementia risk, there is a call for political parties to prioritize brain health and address these risk factors across the UK.
