Alzheimer's - Dementia, Author Interviews, Lipids, Vanderbilt / 18.01.2026

MedicalResearch.com Interview with: [caption id="attachment_72035" align="alignleft" width="200"]Leslie S. Gaynor, PhDClinical Neuropsychologist & Assistant Professor of Medicine Division of Geriatric Medicine Department of Medicine Vanderbilt University Medical Center Nashville, TN 37203 Dr. Gaynor[/caption] Leslie S. Gaynor, PhD Clinical Neuropsychologist & Assistant Professor of Medicine Division of Geriatric Medicine Department of Medicine Vanderbilt University Medical Center Nashville, TN 37203 MedicalResearch.com: What is the background for this study? Response: The US population is rapidly aging, and the oldest members of our population are also the most vulnerable to developing clinical dementia. We are interested in studying older adults ages 80+ who display cognitive resilience despite this increased risk of dementia and actually display exceptional memory performance compared to their same-aged, typically performing peers. These “SuperAgers,”—i.e., 80+-year-old adults with memory performance that is comparable to or surpasses that of adults 20 to 30 years their junior—may hold the key to uncovering genetic factors that predict exceptionally healthy longevity.
Alzheimer's - Dementia, Infections / 19.12.2024

MedicalResearch.com Interview with: [caption id="attachment_65601" align="alignleft" width="200"]Benjamin Readhead PhDResearch Associate Professor Banner Neurodegenerative Disease Research Center Biodesign Institute Arizona State University Dr. Readhead[/caption] Benjamin Readhead PhD Research Associate Professor Banner Neurodegenerative Disease Research Center Biodesign Institute Arizona State University MedicalResearch.com: What is the background for this study? Response: Our study describes a surprising link between an intestinal infection with a common virus, human cytomegalovirus (HCMV), and the development of Alzheimer’s in a subset of people with the disease. In a study published earlier this year in the journal Nature Communications, we found that research participants with Alzheimer’s disease were more likely than those without it to harbor a particular immune cell type (“CD83(+) microglia”) in their brains. While trying to uncover what might be driving the presence of these CD83(+) microglia, we discovered an antibody (IgG4) in the intestine of these same subjects that were suggestive of the possibility that some kind of infection might contribute to this form of the disease.
Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Sleep Disorders / 18.03.2022

MedicalResearch.com Interview with: Peng Li, Ph.D. Assistant Professor of Medicine, Harvard Medical School Research Director, Medical Biodynamics Program (MBP) Division of Sleep and Circadian Disorders Associate Physiologist, Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study?  Response: People commonly see increased sleep during daytime in older adults. In people with Alzheimer’s disease or dementia, daytime drowsiness or sleepiness are even more common. Prior studies have showed protective effects of short naps on cognitive performance and alertness acutely, while also there are studies that have demonstrated more daytime naps are associated with faster cognitive decline in the long-term. We sought to investigate whether daytime napping behavior predicts future development of Alzheimer’s dementia. And we noted that there had been no studies to date that have documented the longitudinal profile of daytime napping during late life objectively.
