A large-scale international review, by the Lancet Commission on Dementia Prevention, Intervention and Care (LCDPIC), suggests that perhaps one in three cases of dementia could be prevented if people took steps to follow healthier lifestyles and so protect their brain health throughout life. This international study, also presented at the Alzheimer’s Association International Conference in London, lists the nine main potentially modifiable risk factors, ranked by importance:
- Mid-life hearing loss (estimated responsible for 9% of risk).
- Failing to complete secondary education (estimated responsible for 8% of risk).
- Smoking (estimated responsible for 5% of risk).
- Failure to seek early treatment for depression (estimated responsible for 4% of risk).
- Physical inactivity (estimated responsible for 3% of risk; or perhaps not).
- Social isolation (estimated responsible for 2% of risk).
- High blood pressure (estimated responsible for 2% of risk).
- Obesity (estimated responsible for 1% of risk).
- Type 2 diabetes (estimated responsible for 1% of risk).
Alcohol consumption / alcohol abuse and poor diet did not make the top ten; although numerous alternative listings are available.
