Dementia and Cognitive Impairment in an Urban Multiethnic Indigenous Community from Amazonas.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.

Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).

Culturally adapted cognitive assessment tool for Indigenous communities in Brazil: Content, construct, and criterion validity.

Introduction: Initial dementia prevalence estimates have revealed a significant burden of the disease in Indigenous communities in Amazonas, Brazil. However, the need for culturally adapted cognitive tools poses a critical challenge when assessing cognitive performance in these communities. This study addressed this issue by culturally adapting and providing validity indicators for the Brazilian Indigenous Cognitive Assessment (BRICA) tool in Manaus, Brazil's urban multiethnic Indigenous community.
