BBC News: Nine lifestyle changes can reduce dementia risk, study says

One in three cases of dementia could be prevented if more people looked after their brain health throughout life, according to an international study in the Lancet.

It lists nine key risk factors including lack of education, hearing loss, smoking and physical inactivity.
The study is being presented at the Alzheimer's Association International Conference in London.
By 2050, 131 million people could be living with dementia globally.
There are estimated to be 47 million people with the condition at the moment.

Nine factors that contribute to the risk of dementia

• Mid-life hearing loss - responsible for 9% of the risk
• Failing to complete secondary education - 8%
• Smoking - 5%
• Failing to seek early treatment for depression - 4%
• Physical inactivity - 3%
• Social isolation - 2%
• High blood pressure - 2%
• Obesity - 1%
• Type 2 diabetes - 1%

These risk factors - which are described as potentially modifiable - add up to 35%. The other 65% of dementia risk is thought to be potentially non-modifiable.
