Dementia has many causes, but research has shown that a mixture of factors, including our age, genetics, lifestyle, environment and health all contribute to whether someone will go on to develop dementia.

The 2020 Lancet Commission report found that up to 40% of dementia cases worldwide could be prevented or delayed by addressing 12 health and lifestyle factors.

Looking after our brains has never been more important. With an ageing population and no treatments currently available in the UK to stop or slow the diseases that cause dementia, we need action now to promote good brain health.

Brain health is a new approach to ensure the potential gains from reducing the risk of developing dementia are maximised.

We’re calling for the government to make brain health a top priority in government health policy, and central to wider ambitions for prevention. We’re also calling for more research to strengthen the evidence around risk reduction and good brain health. We have worked with government to enable the roll-out of dementia risk reduction messaging in all NHS Health Checks.

Brain Health: A new way to think about dementia risk reduction

How we can use ‘brain health’ to transform the public’s attitude towards dementia risk reduction and raise awareness of the importance of looking after brain health throughout life.

Eliminating 12 modifiable risk factors could reduce dementia cases by 40%

A new report has estimated that the number of dementia cases worldwide could be reduced by 40% if 12 risk factors for the condition could be completely eliminated.
