Dementia prevention, intervention, and care: 2020 report of the Lancet Commission
The number of older people, including those living with dementia, is rising, as younger
age mortality declines. However, the age-specific incidence of dementia has fallen
in many countries, probably because of improvements in education, nutrition, health
care, and lifestyle changes. Overall, a growing body of evidence supports the nine
potentially modifiable risk factors for dementia modelled by the 2017 Lancet Commission
on dementia prevention, intervention, and care: less education, hypertension, hearing
impairment, smoking, obesity, depression, physical inactivity, diabetes, and low social
contact.
