Fifty-nine organisations and experts from across the dementia and public health community, including practitioners and researchers, have signed a consensus statement calling for steps to be taken to reduce the risk of dementia for the population. The agreement, known as the Blackfriars Consensus Statement, says that the scientific evidence on dementia risk reduction is evolving rapidly and is now sufficient to justify action to incorporate dementia risk reduction into health policies and to raise wider awareness about which factors can reduce the risk of developing dementia.
