Dr. Anna Zamora-Kapoor’s pilot project will improve our knowledge about sex differences in the associations between obesity, vascular brain injury, and cognitive performance in American Indians. She will leverage data from the Cerebrovascular Disease and its Consequences in American Indians (CDCAI), to explore the potential role of two different measures of obesity, body mass index and waist circumference, in vascular brain injury and cognitive performance outcomes, as well as their variability by sex. This is the first study to examine sex differences in the complex associations between obesity and cognitive performance in American Indian elders.
Dr. Luciana Mascarenhas Fonseca’s pilot project aims to characterize the cross-sectional relationship between intraindividual cognitive variability and cerebral magnetic resonance imaging (MRI) correlates of neurodegeneration in American Indians. She will use data collected in the Cerebrovascular Disease and its Consequences in American Indians (CDCAI) Study. The study is particularly novel as it is the first to investigate intraindividual cognitive variability and neuroimaging in American Indians and may help to identify cognitive noninvasive markers of neurodegeneration in this population.
Dr. Jaedon Avey’s pilot project aims to identify clinical factors associated with differences in health service utilization following diagnosis of Alzheimer’s disease and related dementias or mild cognitive impairment. The project will use data collected at Alaska Native Medical Center and Southcentral Foundation in Anchorage Alaska. The project’s results may inform the management of ADRD within the Alaska Native Tribal Healthcare system and in other Tribal healthcare organizations.
Dr. Heehyul Moon’s pilot project seeks (1) to better understand the disparities in dementia prevalence and modifiable risk factors as well as their effects on trends in cognitive impairment among American Indian older adults, and (2) to increase our understanding of trends in prevalence and their associations with changes in functional disabilities (activities of daily living (ADLs) and instrumental activities of daily living (IADLs)) compared to other racial/ethnic groups (Non-Hispanic Whites; Non-Hispanic Blacks; Hispanics). Data for the proposed study will come from a nationally representative study, the National Health, and Aging Trend Study (NHATS), for the years 2011-2018. This is the first study to investigate the prevalence, risk factors, and trajectories of cognitive impairment among American Indian older adults using nationally representative databases.
Dr. Patrik Johansson’s pilot project seeks to better understand cognitive function of and barriers and facilitators for American Indians participating in Alzheimer’s disease and related dementias (ADRD) research in the eastern United States.
