Family Ties: How Family History Affects Alzheimer’s Risk

Posted on

How important is one’s family history when determining Alzheimer’s risk? Returning guests Drs. Jessica Langbaum and Sterling Johnson discuss the latest research on family history and genetic risk factors and share their perspectives on the topic, specifically focusing on the role of the APOE gene as a risk factor.

Finley Professor of Geriatrics and Dementia, UW School of Medicine and Public Health, and Jessica Langbaum, PhD, senior director of research strategy, Banner Alzheimer’s Institute, overseer, Observational Research Program, Clinical Trials Program, Alzheimer’s Prevention Initiative, director, Alzheimer’s Prevention Registry, director, Arizona Alzheimer’s Disease Research Center

REVEALing APOE Results: Making Genetic Disclosures in Alzheimer’s Research

Posted on

On this episode of Dementia Matters, Dr. Scott Roberts talks about disclosing genetic test results for APOE, a gene that can increase one’s likelihood of developing Alzheimer’s disease. While this information can be concerning, Dr. Roberts shares that it can empower individuals to take the necessary precautions to lower their risk of developing the disease. He discusses the Risk Evaluation and Education for Alzheimer’s Disease (REVEAL) study, walks us through the APOE disclosure process and shares how it is evolving with the development of new Alzheimer’s treatments.

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.

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.
