Study Shows APOE Gene Affects Hispanic Populations’ Risk of Cognitive Decline Differently to Non-Hispanic Populations

Posted on

The APOE gene is recognized as a significant genetic risk factor for cognitive decline, with different alleles, like APOE e2, being seen as protective against decline and others, like APOE e4, indicating an increased risk for cognitive decline. However, new studies are looking at whether these trends are universal across different racial and ethnic groups. Dr. Cally Xiao joins the podcast to discuss her study, which focuses on how different APOE alleles affect risk for Alzheimer’s disease within Hispanic populations compared to non-Hispanic populations.

Dr. Natascha Merten joins the podcast to discuss her study focused on trends in cognitive function across generations. Merten also explains her research on the associations between sensory and motor functions and blood-based biomarkers for neurodegeneration and dementia.

Study Shows APOE e4 Not Associated with Alzheimer’s Disease in American Indian Populations

Posted on

Researchers typically recognize the APOE e4 gene as a significant genetic risk factor for cognitive decline and dementia. However, a new study has found that the allele is not linked to neurodegeneration for all races and ethnic groups, specifically for American Indian populations. Dr. Astrid Suchy-Dicey joins the podcast to discuss her study, the importance of representation in Alzheimer’s disease research, hypotheses for why this allele isn’t a risk factor for all populations and what it means for research going forward.

Alzheimer’s Prevention Initiative investigates genetic risk of Alzheimer’s disease

Posted on

Research data collected from participants around the world has grown our understanding of genetic risk for Alzheimer’s disease. Guest Jessica Langbaum, PhD, is the co-director of the Alzheimer’s Prevention Initiative at Banner Alzheimer’s Institute, which conducts clinical trials in people at high risk for developing Alzheimer’s disease. Langbaum discusses some recent findings in genetic predisposition for Alzheimer’s disease, the psychological consequences of learning one’s risk, and testing interventions to delay or prevent the onset of symptoms.

DNA Is Not Your Destiny: Genetics and Alzheimer’s Disease Risk

Posted on

This episode explores genetic risk factors for early- and late-onset Alzheimer’s disease. Host Nathaniel Chin and guest Corinne Engelman discuss the research looking into genetic risk for Alzheimer’s disease and the uncertainty that comes with genetic testing.
