The Lancet: Do 12 well to prevent 40% dementia.

There is growing evidence to support the Nine potential modifiable risk factors modeled by the Lancet Commission for dementia prevention, intervention and care in 2017, including low levels of education, high blood pressure, hearing impairment, smoking, obesity, depression, lack of exercise, diabetes and low social exposure.
a recent review published in The Lancet added three new and compellingly documented risk factors, including excessive drinking, traumatic brain injury and air pollution, to the nine previous dementia risk factors.
, based on a review of the latest evidence by 28 of the world's leading dementia researchers, focuses on these 12 modifiable risk factors over the course of an individual's life or can prevent or slow the onset of 40 per cent of dementia worldwide.
"dementia" often ask me what I can do to prevent myself from developing dementia.
," said David Ames of the University of Melbourne in Australia, one of the authors of the review.
e.g., stop smoking; limit your weekly drinking to less than 21 units; keep your body's systolic blood pressure below 130mmHg from age 40; avoid activities that can lead to head injuries; encourage the use of hearing aids to treat hearing loss; maintain a healthy diet, exercise regularly and socialize.
even older people can delay or even prevent dementia by taking steps to improve their lifestyle, Ames said: "It's not too early or too late to think about reducing the risk of dementia at any time."
addition to making recommendations to individuals, the review calls on governments to protect people from the risk of dementia by providing primary and secondary education, improving air quality, promoting healthy behaviour and discouraging smoking and alcohol abuse.
the prevalence of dementia in some high-income countries, such as the UK, the US and France, has fallen in recent decades, possibly due to improvements in education, nutrition and health care.
ames, this suggests that preventive health measures can have an impact on dementia.
, two thirds of dementia cases occur in low- and middle-income countries, where education is often less accessed and where smoking, obesity and diabetes are relatively high.
" means that the potential prevention rate of dementia is even higher than in high-income countries.
," said Adesola Ogunniyi of the University of Ibadan in Nigeria, one of the authors of the review.
Ogunniyi said government interventions, such as increased education and anti-smoking campaigns, could have a greater impact on low- and middle-income countries.
, for example, by reducing these 12 risk factors, about 56 per cent of dementia cases in Latin America can be prevented or delayed.
however, the effectiveness of lifestyle interventions to prevent dementia is limited, as the brain inevitably stops working as we age, especially those who live past 100.
are very good at preventing people from dying from certain diseases, which means that life expectancy is very high now," said Ames, a new president.
but if you live long enough, you'll end up with a disease, and dementia is one of them.
