Introduction: The incidence rate of Alzheimer's disease (AD) was found to be 2 times lower in Yoruba than in African Americans. This study was aimed at identifying the factors associated with increased risk of incident AD in the two communities. Methodology: A two-stage design with initial screening using the CSI’D followed by neuropsychological test(More)
Epidemiologic studies on dementia generally have 2 major interacting objectives: descriptive, where rates of dementia and Alzheimer Disease (AD) are calculated for communities and selected populations, and analytic, which attempt to explain the observed phenotypic variations in communities and populations by identifying disease risk factors. The public(More)
Within the context of the ACTIVE study, the current investigation explored the relationships between objective memory and two components of subjective memory (frequency of forgetting and use of external aids) over a five-year period. Relationships were assessed using parallel process latent growth curve models. Results indicated that changes in objective(More)
The effectiveness of anger assessment in classifying self-report of aggressive behavior was examined using a sample of normal college students. Paper-and-pencil measures of anger (Novaco Anger Inventory and Spielberger's Trait Anger scale) were not effective in accurately classifying subjects high and low in self-report of aggressive behavior.

OBJECTIVES To describe the incidence of cardiovascular risk factors, or race-related disparities in incidence, across the age spectrum in adults. DESIGN Longitudinal cohort. SETTING National sample. PARTICIPANTS Community-dwelling black and white adults recruited between 2003 and 2007. MEASUREMENTS Incident hypertension, diabetes mellitus,(More)
BACKGROUND AND PURPOSE At age 45 years, blacks have a stroke mortality ≈3× greater than their white counterparts, with a declining disparity at older ages. We assess whether this black-white disparity in stroke mortality is attributable to a black-white disparity in stroke incidence versus a disparity in case fatality. METHODS We first assess if(More)
Although cognitive dysfunction is a prevalent and disruptive problem for many breast cancer survivors (BCSs), little research has examined its etiology. One potential mechanism that remains to be explored is serotonin. Serotonin has been implicated in normal and dysfunctional cognitive processes, and serotonin levels are significantly affected by estrogen(More)
