Dementia Matters

New Study Examines the Effects of Food Insecurity on Dementia Risk

The latest Household Food Security report estimated that 13.7% of U.S. households experienced food insecurity in 2024. This lack of access to a nutritious diet can significantly affect health, so how does it then impact older adults’ health and their risk for cognitive impairment? Dr. Heejin Lee joins the podcast to share what food insecurity means, how it can affect a person’s overall health and what her study found about its effect on dementia and cognitive impairment, as well as resources for those experiencing food insecurity.

Guest: Heejin Lee, PhD, postdoctoral research fellow, department of nutrition, Harvard T.H. Chan School of Public Health

Navigating Difficult Conversations about Driving and Dementia

Driving can be a sensitive topic as a person gets older, and especially so when someone begins experiencing cognitive decline or is diagnosed with dementia. How can family members and care partners discuss their concerns about a loved one’s ability to drive while still respecting their dignity, autonomy and independence? Dr. KJ Hansmann joins the podcast to share strategies for how to talk about a loved one’s driving habits and how to plan to help them stop driving as they navigate cognitive decline, as well as what signs to look out for when assessing their ability to drive and what resources are available for both those living with cognitive decline and their care partners.

On the Pulse: How Resting Heart Rate Improves a Dementia Risk Score’s Accuracy

What if your heartbeat could help determine your dementia risk? The CAIDE dementia risk score has long helped clinicians estimate midlife risk for dementia using cardiovascular health factors, but its accuracy hasn’t been equal across populations. New research suggests that integrating resting heart rate meaningfully improves predictive performance across most racial groups. In this interview, Dr. Newman Sze and Shakiru Alaka join us to dig into how and why resting heart rate enhances CAIDE’s accuracy, what the data shows across different racial groups, and what this could mean for earlier, more equitable identification of dementia risk in both research and clinical settings.

Guests: Newman Sze, PhD, professor of health sciences, Brock University, Canada Research Chair in Mechanisms of Health and Disease, and Shakiru Alaka, MS, senior analyst, Canadian Institute for Health Information, data scientist, Western University

Could Managing Four Common Health Conditions Slow Cognitive Decline from Alzheimer’s?

Alzheimer’s disease isn’t always the only health condition a person faces, so how does treating other diseases impact the progression of Alzheimer’s? Researchers at the University of Arizona focused on four common health conditions – type two diabetes, hypertension, inflammation and dyslipidemia – which are known to increase the risk of developing Alzheimer’s disease, and set out to investigate whether those diagnosed with Alzheimer’s who received treatments for these four conditions also saw a delay in cognitive decline. Dr. Barb Bendlin joins the podcast to break down the findings from this research, as well as discuss the impact of personalized prevention strategies and combination therapies.

Guest: Barbara Bendlin, PhD, professor, Division of Geriatrics and Gerontology, University of Wisconsin (UW) School of Medicine and Public Health, deputy director, UW Center for Health Disparities Research (CHDR)

Taking Steps to Slow Decline: New Study Examines the Role of Physical Activity on Alzheimer’s Progression

10,000 – that’s the magic number of steps often recommended for a healthy lifestyle. With recent research looking into whether that number is an accurate benchmark for health, could the number of steps taken per day have an impact on brain health and, specifically, cognitive decline? That’s precisely what a new study from Harvard Medical School and Mass General Brigham sought to examine, looking at how physical activity, specifically step count, impacted cognitive decline for those living with Alzheimer’s disease. Dr. Bri Breidenbach and Sarah Lose join the podcast to break down the results of this new study, as well as share what current research says about the effect of other kinds of physical activity, such as different intensity exercises, on the brain and Alzheimer’s progression.
