Cerebrovascular Correlates of Dementia in Rural Communities - The Three Villages Study

This study aims to assess the prevalence and severity of dementia in an established cohort of community-dwelling older adults living in three neighboring rural Ecuadorian villages (Atahualpa, El Tambo, and Prosperidad), as well as to evaluate clinical and neuroimaging correlates of dementia in the study population. By the use of the Clinical Dementia Rating Scale (CDRS), the study also aims to assess the lower cutoff of the MoCA that better correlates with the occurrence of dementia in the study population. In addition, this study will provides grounds for the initiation of a prospective cohort study to assess factors influencing the development of dementia in the follow-up.
