The purpose of this Editorial is to summarise the key recommendations of the Lancet Commission on Dementia Prevention, Intervention, and Care, reporting on the best available evidence to date on what we can do to prevent and intervene for dementia. We briefly describe the new life-course model of dementia prevention incorporating nine modifiable risk factors and their potential effect in reducing individuals' risk of dementia. We also summarise the recommendations of the report about which pharmacological, psychological, and social interventions are effective, and improve outcomes for people with dementia and their families. Recent developments highlight that there is good potential for the prevention of dementia. Progress in evidence-based approaches indicate the potential for dementia care to be of high-quality and widely accessible. Acting upon this knowledge now will reduce the global burden of dementia and improve the lives of people living with dementia and their families.
