The causes of dementia have particularities inherent to different regions of the world. Particularly, the low socioeconomic level, low access to health services and ethnic diversity in Brazil and other Latin American countries are risk factors unique to our region when compared to the risk factors for dementia in rich countries. However, much of what we know about the epidemiology of dementia comes from studies using American and European data, which limits the validity of these findings in low- and middle-income countries. Thus, Suemoto Lab is a multidisciplinary and diverse research group that seeks to understand the epidemiology of dementia, with an emphasis on studies that use data from large Brazilian studies and other Latin American countries.
