From pollution to coffee, there are a number of factors believed that raise
or reduce a persons risk of developing dementia. Now scientists have
developed a chart to show which are the most important steps to take.
The scientists, Dr. Ruth Peters, a UK neuropsychologist, and Kaarin J.
Anstey, an Australian expert on aging, evaluated the latest information from
clinical trials and studies on dementia to come up with a chart to show the
different risks.
They particularly focused on the factors that are in our power to change --
such as weight, blood pressure and alcohol intake.
The findings from the latest research shows that eating a large amount of
fatty foods and living in a polluted area may increase dementia risk, whereas
taking regular exercise and keeping cholesterol at healthy levels may lower
risk, they say.
"The evidence is increasingly suggesting that keeping a healthy blood
circulation throughout the body is crucial for lowering dementia risk - in
other words, what is good for your heart is good for your brain, Peters
says.
Factors that raise dementia risk:
- Excess alcohol
- Poor diet
- Smoking
- Unhealthy weight
- High blood pressure
- High cholesterol
- Diabetes
- Stroke
- Air pollution
Factors that lower your risk:
Regular physical activity
Moderate amounts of caffeine
Social engagement
Brain training.
