The Maracaibo Aging Study is a longitudinal, population-based, one-step multidisciplinary study of age-related diseases, with a particular focus on memory-related disorders, among subjects over 55 years living in a neighborhood of the city of Maracaibo, Venezuela. Three phases were scheduled for this study. First, a door-to-door survey was conducted in(More)
An ongoing longitudinal study in Maracaibo, Venezuela, examined the interaction between apolipoprotein E (APOE) genotypes and Alzheimer's disease (AD) and vascular dementia (VD), evaluating age and gender as potential modifiers of risk. Overall, carriers of at least one epsilon4 allele were at higher risk for AD, not for VD; however, the risk was(More)
OBJECTIVES The present study generated baseline data for total homocysteine (tHcy) in elderly Caribbeans of Hispanic ancestry, residing in Venezuela, their country of origin. DESIGN AND METHODS 2106 participants in the Maracaibo Aging Study (MAS), older than 55 years, underwent standardized clinical and laboratory assessments, including measurement of(More)
BACKGROUND/AIMS People in Caribbean countries are thought to be at particularly high risk for dementia. Basic descriptive epidemiology of dementia is required for populations in the region to determine the validity of this hypothesis. The main objectives of the study were to assess the prevalence, types and severity of dementia among elderly people (>or=55(More)
The relationship between total homocysteine (tHcy) and dementia risk remains controversial, as the association varies among populations and dementia subtypes. We studied a Venezuelan population that has high prevalence of both elevated tHcy and dementia. We tested the hypotheses that (1) elevated tHcy is associated with increased dementia risk, (2) the risk(More)
