Background: Dementia will concern more and more people in the developing countries, but the perception people have of dementia in these areas has not yet been studied.
Method: During a general population survey (EDAC) carried out in Brazzaville (Republic of Congo), 27 elderly persons suspected of having dementia and 31 of their relatives, 90 cognitively impaired elderly persons and 92 of their relatives, as well as 33 hospital workers were interviewed according to the Explanatory Model Interview Catalogue.
Results: Item prominence ratings indicate that the attention was mainly on the emotional and socio-economic consequences (scores >1.0 out of 5 points). Ageing and mental stress are the main perceived causes. Hospital workers are more aware of public stigma.
Conclusion: The socio-cultural components of the dementia phenomenon have to be taken into account to enforce public health and social measures.
