The Alzheimer's Disease Sequencing Project (ADSP) undertook whole exome sequencing in 5,740 late-onset Alzheimer disease (AD) cases and 5,096 cognitively normal controls primarily of European ancestry (EA), among whom 218 cases and 177 controls were Caribbean Hispanic (CH). An age-, sex- and APOE based risk score and family history were used to sel...
Article
Background: Small vessel cerebrovascular dysfunction that manifests on MRI as white matter hyperintensities(WMH), is linked to increased risk and progression of Alzheimer's disease(AD), but there is considerable debate about whether it represents a core feature of the disease. Parental history of dementia is a risk factor for AD, suggesting a stro...

Full-text available
Age at onset of Alzheimer's disease is highly variable, and its modifiers (genetic or environmental) could act through epigenetic changes, such as DNA methylation at CpG sites. DNA methylation is also linked to ageing-the strongest Alzheimer's disease risk factor. DNA methylation age can be calculated using age-related CpGs and might reflect biolog...
Article
Introduction: The associations between self-reported current and past leisure time physical activity (LTPA) and Alzheimer's disease (AD) incidence were determined using data from the multiethnic Washington/Hamilton Heights-Inwood Columbia Aging Project (WHICAP) study. Methods: The metabolic equivalent of LTPA energy expenditure was calculated fo...
Article
To analyze family-based whole-genome sequence (WGS) data for complex traits, we developed a rare variant (RV) non-parametric linkage (NPL) analysis method, which has advantages over association methods. The RV-NPL differs from the NPL in that RVs are analyzed, and allele sharing among affected relative-pairs is estimated only for minor alleles. Ana...

Introduction: The present study sought to determine whether cognitive trajectories differ between men and women across and within racial/ethnic groups. Methods: Participants were 5258 non-Hispanic White (NHW), Black, and Hispanic men and women in the Washington/Hamilton Heights-Inwood Columbia Aging Project who were administered neuropsychologic...
Article
Full-text available
Introduction: This study aimed to determine if later birth year influences trajectory of age-related cognitive decline across racial/ethnic groups and to test whether years of school, childhood socioeconomic status, and cardiovascular disease burden explain such secular trends. Methods: We compared cognitive trajectories of global cognition and...
Article
Introduction: Odor identification deficits characterize Alzheimer's disease and other dementias. We examined if intact performance on brief cognitive and odor identification tests predicts lack of transition to dementia. Methods: In an urban community, 1037 older adults without dementia completed the 40-item University of Pennsylvania Smell Iden...
Article
Objectives: Greater depressive symptoms are associated with cognitive decline in older adulthood, but it is not clear what underlying factors drive this association. One behavioral pathway through which depressive symptoms may negatively influence cognitive functioning is through activity engagement. Prior research has independently linked greater...
