Risk reduction of cognitive decline and dementia | The World Health Organisation

These WHO guidelines provide evidence-based recommendations on lifestyle behaviours and interventions to delay or prevent cognitive decline and dementia. Worldwide, around 50 million people have dementia and, with one new case every three seconds, the number of people with dementia is set to triple by 2050. The increasing numbers of people with dementia, its significant social and economic impact and lack of curative treatment, make it imperative for countries to focus on reducing modifiable risk factors for dementia.
These guidelines are intended as a tool for health care providers, governments, policy-makers and other
stakeholders to strengthen their response to the dementia challenge.
