AIM To assess the relationship between cognitive status and self-reported symptoms of depression, anxiety and stress of older adults living in an underserved rural South American population. METHODS Community-dwelling Atahualpa residents aged ≥60 years were identified during a door-to-door census, and evaluated with the Depression Anxiety Stress Scale-21(More)
OBJECTIVE To estimate the prevalence of Willis-Ekbom disease (WED) in a racially homogeneous population of adults Amerindians living in rural coastal Ecuador, and to assess the reliability of the International Restless Legs Syndrome Study Group (IRLSSG) questionnaire when used in population-based studies. METHODS Two-phase, door-to-door, population-based(More)
Calcified neurocysticercosis has been associated with hippocampal atrophy in patients with refractory epilepsy, but the relevance of this association in the population at large is unknown. We assessed calcified cysticerci and its association with hippocampal atrophy in elderly persons living in Atahualpa, an Ecuadorian village endemic for(More)
RATIONALE Stroke and cardiovascular diseases will be the next health epidemics in Latin America due to increased life expectancy and changes in the lifestyle and dietary habits of the population. Knowledge of the cardiovascular health status of the inhabitants will allow the implementation of policies directed to reduce the burden of stroke and(More)
All studies attempting to find an association between vitamin D deficiency and cerebrovascular diseases have been conducted at latitudes far away from the Equator, where living conditions, cardiovascular risk factors, and sunshine exposure are different from tropical regions. We aimed to assess cerebrovascular correlates of vitamin D deficiency in(More)
Studies in industrialized nations suggest that severe edentulism correlates with cognitive impairment, but there is little information on this association in underserved populations. We conducted a community-based study to assess whether edentulism associates with cognitive impairment in elders living in rural Ecuador. Atahualpa residents aged ≥60 years(More)
Stroke will be South America's next epidemic. Therefore, information on stroke particularities in the region will help to overcome its impact burden. We evaluated prevalence, pattern of sub-types, and pathogenic mechanisms underlying stroke in Atahualpa, a village representative of rural coastal Ecuador. In a three-phase epidemiologic study, suspected cases(More)

Proper assessment of this condition may be complicated by illiteracy and cross-cultural factors. We conducted a population-based study in elders living in rural Ecuador to evaluate whether the MoCA associated with structural(More)
BACKGROUND Calcified cysticerci share the morphology and signal properties with true cerebral microbleeds, but this condition is neglected at the time of evaluating MRIs for clinical or research purposes. We report our experience with the MRI reading obtained from the Atahualpa Project, a population-based stroke study, conducted in a village endemic for(More)
