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.
A study being presented at the Alzheimer's Association International Conference in London lists 9 key lifestyle 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 thought to be modifiable - add up to 35%. The other 65% of dementia risk is beyond the individual's control.
What are everyone's thoughts on the steps you can take to help with the modifiable 35%? Do the results of this study surprise you?
