Abstract
Background
Data from high‐income countries (HICs) suggest a decline in age‐specific incidence rates of dementia. However, this has happened primarily in HICs, with low‐ and middle‐ income countries (LMICs) facing two main challenges: a higher burden of risk factors and, in general, a faster ageing population. Most people with dementia live in LMICs, and this is set to increase, thus requiring urgent and robust action to prevent, treat and support people with dementia and their families.
Methods
We, in the Lancet Commission, reviewed the most recent literature, and conducted a new metanalysis on worldwide dementia risk. We have calculated worldwide figures, although there may be variation in different ethnic and socioeconomic groups.
Results
Dementia studies are overwhelmingly from HICs, and there is a tendency to recruit people of European origin with higher education and socioeconomic status, with few people from ethnic minority groups. The same applies in respect of worldwide clinical trials, including multicomponent interventions to reduce risk, biomarker research and pharmacological/non‐pharmacological interventions.
Although most interventions are developed in HICs, culturally adapted interventions seem to be as effective in LMICs as in their original context, as long as the interventions’ core components are not compromised in the adaptation process.
Conclusion
Policy interventions can improve dementia prevention, particularly in LMICs and in minority and lower level socio‐economic groups ‐ precisely the people who have the greatest burden of modifiable risk and are more likely to develop dementia.
Dementia prevention efforts should be tailored to the needs of the different countries and different groups within countries. Trials and research databases should aim for sociodemographic diversity to reflect real life populations.
Although evidence‐based interventions developed in HICs can be effective in LMICs, there is often a lack of healthcare infrastructure and resources to deliver them. Moreover, cultural differences can make them inappropriate or less effective. Interventions should be developed in partnership with local communities to ensure their appropriateness in respect of the culture, beliefs and practises which vary within and between countries.
