What if there was a way to detect Alzheimer’s disease before clinical signs and symptoms even appeared? Dr. Reisa Sperling joins Dementia Matters for a two-part series covering her research on detecting and treating Alzheimer’s disease at the earliest possible stage, known as preclinical Alzheimer’s. In this episode, Dr. Sperling goes in-depth on amyloid and tau proteins and the implications on early detection and treatment strategies for Alzheimer’s disease.

An expanding field of research is looking at how the gut affects different parts of people’s health, but how does it affect brain health? Drs. Barb Bendlin and Tyler Ulland join the podcast to talk about their 2023 study, which suggests a link between gut health, aging and changes related to Alzheimer’s disease. They discuss their findings on how gut inflammation could impact brain health, as well as explain what it means to have good gut health and how food, medications, where one lives and other factors can impact the gut microbiome. Guests: Barbara Bendlin, PhD, professor, Division of Geriatrics and Gerontology, deputy director, University of Wisconsin (UW) Center for Health Disparities Research, and Tyler Ulland, PhD, associate professor of pathology and laboratory medicine, UW School of Medicine and Public Health, leader, Ulland Lab Show Notes Learn more about the 2024 Fall Community Conversation: The Impact of Social Connections on Brain Health and register to attend in person on our website.

In this compendium episode, we review some of the best information and research that we’ve shared on the six pillars of brain health. With excerpts highlighting the importance of physical activity, diet, sleep, social engagement and more, our six guests show that there are numerous evidence-based lifestyle interventions that a person can incorporate into their daily lives to improve their brain health and delay the onset of or reduce their risk of developing Alzheimer’s disease.

While genetics and lifestyle can influence one’s risk of developing Alzheimer’s disease, other unexpected factors can shift the possibility. One of these factors is personality. Dr. Emorie Beck joins Dementia Matters to share her research on the link between personality and Alzheimer’s risk. Dr. Beck breaks down the Big Five traits that make up someone’s personality and their effects on a person’s cognitive health.  Guest: Emorie Beck, PhD, assistant professor, University of California, Davis Show Notes Read Dr. Beck’s study, “Personality predictors of dementia diagnosis and neuropathological burden: An individual participant data meta-analysis,” through the Alzheimer’s Association Journals website.
