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.

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.

Talking TBI: The Impact of Traumatic Brain Injuries on Cognitive Decline

Traumatic brain injuries (TBI) like concussions are not uncommon, especially in children and older adults. These injuries can have both short-term and lasting effects on the brain, but what about their impact on cognitive function? Dr. Deling He of UW–Madison’s Cognitive-Communication in Aging and Neurogenic Disorders Laboratory (CCANDL) lab joins the podcast to discuss her research on the connections between TBI, speech pathology and cognition and what her study findings mean for people with a history of TBI.

Taking a Positive Approach to Dementia Care with Strategies from Teepa Snow

Caring for someone living with dementia can be both deeply meaningful and incredibly challenging. Finding effective ways to connect, communicate and provide support often requires shifting how we see and respond to changes in the brain. In honor of National Family Caregivers Month, renowned dementia care specialist Teepa Snow joins the podcast to share her insights on improving life with dementia through empathy and understanding. As the founder of Positive Approach to Care (PAC), Teepa has developed the Snow Approach, a set of practical and compassionate techniques designed to empower care partners. She discusses the philosophy behind her methods, the importance of recognizing retained abilities and strategies that can make daily interactions more positive and meaningful for both care partners and those living with dementia.
