Alzheimer's - Dementia, Author Interviews, Genetic Research, JAMA, Stanford / 07.11.2023

MedicalResearch.com Interview with: Michael E. Belloy, PhD Department of Neurology and Neurological Sciences Stanford University, Stanford, California MedicalResearch.com: What is the background for this study? Response: Apolipoprotein E (APOE)*2 and APOE*4 are, respectively, the strongest protective and risk-increasing, genetic variants for late-onset Alzheimer disease. As such, one’s APOE genotype is highly relevant towards clinical trial design and Alzheimer’s disease research. However, most insights so far are focused on the associations of these APOE genotypes with Alzheimer’s disease risk in non-Hispanic white individuals. One important aspect of our work is that we really increased sample sizes for non-Hispanic Black, Hispanic, and East Asian individuals, so that we now have better understanding of the associations of APOE genotypes with Alzheimer’s disease risk in these groups. In complement, we also did the largest investigation to date on the role of ancestry on the associations of APOE genotypes with Alzheimer’s disease risk. The scale of our study was thus a critical factor in generating novel insights. (more…)

MedicalResearch.com Interview with: Dr. Claude Alain PhD Senior Scientist Baycrest's Rotman Research Institute  MedicalResearch.com: What is the background for this study? Response: Adults carrying a gene associated with a higher risk of Alzheimer’s disease had a harder time accessing recently acquired knowledge, even though they didn’t show any symptoms of memory problems.  MedicalResearch.com: What are the main findings?  Response: Researchers found that older adults carrying a specific strain of the gene, apolipoprotein E4, otherwise known as APOE4, weren’t able to tap into information they had just learned to assist them on a listening test. These findings suggest greater difficulty for these individuals to access knowledge from their memory to guide their attention in ways that would have improved their performance. This work could lead to the development of new ways to detect individuals at risk. (more…)
